BACKGROUND OF THE INVENTION
[0003] Cancer is a serious public health problem in the United
States and other developed countries. Currently, one in four deaths
in the United States is due to cancer. Cancer therapy involves
treating patients with chemotherapeutic drugs to kill tumor cells.
However, subsets of tumor cells are frequently resistant to drug
therapy and survive to re-populate at sites of origin and at
distant metastatic sites, leading to detectable disease recurrence
and morbidity. Many carcinoma tumor cells that have the properties
of increased invasive and metastatic capacity, and altered drug
resistance, are thought to have undergone a morphological
transformation encompassing or similar to EMT
(epithelial-mesenchymal transition). Cells undergoing EMT lose the
normal adhesive properties of epithelial cells and undergo a
spectrum of changes including loss of E-cadherin expression and
expression of mesenchymal markers, increased motility, increased
invasiveness, and increased resistance to cell death.
[0004] The leading therapies for cancer are currently surgery,
radiation and chemotherapy. Chemotherapeutic approaches such as
anti-tumor antibiotics, alkylating agents, nitrosourea compounds,
vinca alkaloids, steroid hormones, and anti-metabolites form the
bulk of therapies available to oncologists. Despite advances in the
field of cancer treatment, cancer remains a major health
problem.
[0005] Angiogenesis, the formation of new blood vessels out of
pre-existing capillaries, is a sequence of events that is of key
importance in a broad array of physiologic and pathologic
processes. Normal tissue growth, such as in embryonic development,
wound healing, and the menstrual cycle, is characterized by
dependence on new vessel formation for the supply of oxygen and
nutrients as well as removal of waste products. A large number of
different and unrelated diseases are also associated with formation
of new vasculature. Among certain pathologies are conditions in
which angiogenesis is low, and should be enhanced to improve
disease conditions. More frequently, however, excessive
angiogenesis is an important characteristic of various pathologies,
including pathologies characterized or associated with an abnormal
or uncontrolled proliferation of cells. Pathologies which involve
excessive angiogenesis include, for example, cancer (both solid and
hematologic tumors), cardiovascular diseases (such as
atherosclerosis and restenosis), chronic inflammation (rheumatoid
arthritis, Crohn's disease), diabetes (diabetic retinopathy),
psoriasis, endometriosis, neovascular glaucoma and adiposity (3).
These conditions may benefit from chemotherapeutic inhibition of
angiogenesis.
[0006] Generally speaking, the angiogenic process entails the
proliferation and migration of a normally quiescent endothelium,
the controlled proteolysis of the pericellular matrix, and the
synthesis of new extracellular matrix components by developing
capillaries. The establishment of new intra- and intercellular
contacts and the morphological differentiation of endothelial cells
to capillary-like tubular networks provide support for their
subsequent maturation, branching, remodeling and selective
regression to form a highly organized, functional microvascular
network. The autocrine, paracrine and amphicrine interactions of
the vascular endothelium with its surrounding stromal components,
as well as with the pro-angiogenic and angiostatic cytokines and
growth factors orchestrating physiologic angiogenesis, are normally
tightly regulated both spatially and temporally.
[0007] Angiogenesis is crucial to the growth of neoplastic tissues.
For more than 100 years, tumors have been observed to be more
vascular than normal tissues. Several experimental studies have
suggested that both primary tumor growth and metastasis require
neovascularization. In contrast to the well orchestrated process
described above for normal tissue growth, the pathologic
angiogenesis necessary for active tumor growth is generally
sustained and persistent, with the initial acquisition of the
angiogenic phenotype being a common mechanism for the development
of a variety of solid and hematopoietic tumor types. Tumors that
are unable to recruit and sustain a vascular network typically
remain dormant as asymptomatic lesions in situ. Metastasis is also
angiogenesis-dependent: for a tumor cell to metastasize
successfully, it generally must gain access to the vasculature in
the primary tumor, survive the circulation, arrest in the
microvasculature of the target organ, exit from this vasculature,
grow in the target organ, and induce angiogenesis at the target
site. Thus, angiogenesis appears to be necessary at the beginning
as well as the completion of the metastatic cascade.
[0008] The criticality of angiogenesis to the growth and metastasis
of neoplasms thus provides an optimal potential target for
chemotherapeutic efforts. Appropriate anti-angiogenic agents may
act directly or indirectly to influence tumor-associated
angiogenesis either by delaying its onset (i.e., blocking an
"angiogenic switch") or by blocking the sustained and focal
neovascularization that is characteristic of many tumor types.
Anti-angiogenesis therapies directed against the tumor-associated
endothelium and the multiple molecular and cellular processes and
targets implicated in sustained pathologic angiogenesis are being
actively evaluated for their safety and efficacy in multiple
clinical trials. However, there has been limited success to date
with the discovery and/or identification of safe and/or effective
anti-angiogenic agents.
[0009] Fibrosis is the abnormal accumulation of fibrous tissue that
can occur as a part of the wound-healing process in damaged tissue.
Such tissue damage may result from physical injury, inflammation,
infection, exposure to toxins, and other causes.
[0010] Liver (hepatic) fibrosis, for example, occurs as a part of
the wound-healing response to chronic liver injury. Fibrosis occurs
as a complication of haemochromatosis, Wilson's disease,
alcoholism, schistosomiasis, viral hepatitis, bile duct
obstruction, exposure to toxins, and metabolic disorders. This
formation of scar tissue is believed to represent an attempt by the
body to encapsulate the injured tissue. Liver fibrosis is
characterized by the accumulation of extracellular matrix that can
be distinguished qualitatively from that in normal liver. Left
unchecked, hepatic fibrosis progresses to cirrhosis (defined by the
presence of encapsulated nodules), liver failure, and death.
[0011] As summarized by Li and Friedman (Gastroenterol. Hepatol.
14:618-633, 1999), actual and proposed therapeutic strategies for
liver fibrosis include removal of the underlying cause (e.g., toxin
or infectious agent), suppression of inflammation (using, e.g.,
corticosteroids, IL-1 receptor antagonists, or other agents),
down-regulation of stellate cell activation using, e.g., gamma
interferon or antioxidants), promotion of matrix degradation, or
promotion of stellate cell apoptosis. Despite recent progress, many
of these strategies are still in the experimental stage, and
existing therapies are aimed at suppressing inflammation rather
than addressing the underlying biochemical processes. Thus, there
remains a need in the art for materials and methods for treating
fibrosis, including liver and lung fibrosis.
[0012] Fibrotic tissues accumulate in the heart and blood vessels
as a result of hypertension, hypertensive heart disease,
atherosclerosis, and myocardial infarction. High blood pressure, or
hypertension, can be cause by a variety of factors and often leads
to the development of Hypertensive Heart Disease (HHD) with
progression to cardiac arrest and myocardial infarction. Similarly,
atherosclerosis and other ischemic heart diseases often also result
in cardiac arrest. These cardiovascular diseases all exhibit an
accumulation of extra-cellular matrix or fibrotic deposition which
results in stiffening of the vasculature and stiffening of the
cardiac tissue itself. This deposition of fibrotic material is a
response to the damage induced by the hypertensive and/or sclerotic
state, but the effects of this response also result in the negative
effects of vascular and cardiac stiffening as well as ventricle
enlargement. Additionally, it is believed that the increased
cardiac fibrosis seen in cardiovascular disease disrupts or alters
the signals transmitted to cardiomyocytes via the tissue
scaffolding of the heart, further leading to disruption of
efficient cardiac function and promoting cardiac arrest and
myocardial infarction.
SUMMARY OF THE INVENTION
[0013] Epithelial-to-Mesenchymal Transition (EMT) refers to the
process whereby a cell with a gene expression/phenotype
characteristic of epithelial cell (i.e., expressing specific
proteins, factors, and molecules) changes or alters the genes or
their level of expression which results in a change in the
phenotype of the cell as exhibited by the alteration or change in
the genes expressed.
[0014] Compositions are needed which prevent EMT and which are
effective in blocking the activity of enzymes such as LOX and
LOXL2. Such inhibitors are useful in treating diseases and
disorders associated with aberrant levels of LOX and LOXL2.
[0015] Antibodies that bind to enzymes can be competitive
inhibitors, uncompetitive inhibitors or non-competitive inhibitors.
With respect to competitive inhibition, an inhibitor usually bears
structural similarity to substrate. Inhibition will be noticeable
at low substrate concentrations, but can be overcome at high
substrate concentrations. With respect to uncompetitive inhibition,
an inhibitor binds at a site that becomes available after substrate
is bound at the active site. Inhibition will be most noticeable at
high substrate concentration. With respect to non-competitive
inhibition, an inhibitor binds at site away from substrate binding
site and relative inhibition will generally be the same at all
substrate concentrations. In one embodiment, an antibody or antigen
binding fragment thereof, described herein specifically binds both
full-length and processed LOX or LOXL2. In one aspect, both
full-length and processed LOX or LOXL2 are active forms of the
enzyme.
[0016] Provided herein is an isolated antibody or antigen binding
fragment thereof, that specifically binds to an epitope having an
amino acid sequence set forth as SEQ ID NO: 6. The antibody or
antigen binding fragment thereof, comprises a variable heavy chain
having at least 75% amino acid sequence identity to an amino acid
sequence set forth as SEQ ID NO: 1 and a variable light chain
having at least 75% amino acid sequence identity to an amino acid
sequence set forth as SEQ ID NO: 2.
[0017] Provided herein is an isolated antibody or antigen binding
fragment thereof, comprising a variable heavy chain having at least
75% amino acid sequence identity to an amino acid sequence set
forth as SEQ ID NO: 1, and a variable light chain having at least
75% amino acid sequence identity to an amino acid sequence set
forth as SEQ ID NO: 2. In one embodiment, an isolated antibody or
antigen binding fragment thereof, comprises a variable heavy chain
having at least 75% amino acid sequence identity to an amino acid
sequence set forth as SEQ ID NO: 1. In another embodiment, an
isolated antibody or antigen binding fragment thereof, comprises a
variable light chain having at least 75% amino acid sequence
identity to an amino acid sequence set forth as SEQ ID NO: 2. In
yet another embodiment, an isolated antibody or antigen binding
fragment thereof, competes with, or specifically binds to, any of
the anti-LOXL2 antibodies or antigen binding fragments thereof
described herein for binding to LOXL2. Antibodies or antigen
binding fragments thereof can specifically bind to LOXL2 with a
binding affinity of at least 2, 5, 10, 50, 100, 500 or 1000 times
greater than to at least one of LOX, LOXL1, LOXL3 or LOXL4.
[0018] Provided herein are humanized anti-LOXL2 antibodies. A
humanized antibody or antigen binding fragment thereof, can
specifically binds to an epitope having an amino acid sequence set
forth as SEQ ID NO: 6. In one embodiment, the humanized antibody or
antigen binding fragment thereof, comprises a variable heavy chain
having at least 75% amino acid sequence identity to an amino acid
sequence set forth as SEQ ID NO: 25, 26, 27 or 28 and a variable
light chain having at least 75% amino acid sequence identity to an
amino acid sequence set forth as SEQ ID NO: 30, 31 or 32.
[0019] A humanized isolated antibody or antigen binding fragment
thereof, can comprise a variable heavy chain having at least 75%
amino acid sequence identity to an amino acid sequence set forth as
SEQ ID NO: SEQ ID NO: 25, 26, 27 or 28, and a variable light chain
having at least 75% amino acid sequence identity to an amino acid
sequence set forth as SEQ ID NO: 30, 31 or 32.
[0020] A humanized antibody or antigen binding fragment thereof,
can comprise a variable heavy chain having at least 75% amino acid
sequence identity to an amino acid sequence set forth as SEQ ID NO:
25, 26, 27 or 28.
[0021] A humanized antibody or antigen binding fragment thereof,
can comprise a variable light chain having at least 75% amino acid
sequence identity to an amino acid sequence set forth as SEQ ID NO:
30, 31 or 32. Combinations of variable heavy chains and variable
light chains can be made to assess binding affinity.
[0022] Provided herein is a humanized antibody or antigen binding
fragment thereof, that competes with, or specifically binds to, an
antibody or antigen binding fragment thereof described herein for
binding to LOXL2.
[0023] Provided herein is a humanized antibody, or antigen-binding

DETAILED DESCRIPTION OF THE INVENTION
[0107] The present invention relates to the field of medicine,
including cancer diagnosis and treatment. One aspect of the
invention relates to LOX and LOXL2 as indicators of disease
progression and a target for therapeutic agents.
[0108] The present invention provides innovative methodology and
related composition and kits for diagnosing or monitoring various
diseases associated with abnormal cell proliferation, angiogenesis
and fibrosis, by using agents that specifically recognize active or
mature forms of lysyl oxidase (LOX) or lysyl oxidase-like (LOXL)
proteins.
[0109] Methods are provided for diagnosing or monitoring cancer
metastasis in a subject, comprising: assessing active LOX or LOXL2
levels or activity in the blood or in a tumor, whereby a change in
active LOX or LOXL2 levels or activity in the blood or in the tumor
in comparison with a reference sample, indicates the presence of
metastatic tumor growth.
[0110] As described in more detail below, levels of active LOX or
LOXL2 can be assessed by various methods including but are not
limited to immunohistochemistry by using antibodies that
specifically bind to the active or mature form of LOX or LOXL2.
Enzymatic activity of active LOX or LOXL2 can be measured by using
various methods including but not limited to chromogenic and
fluorometric assays.
[0111] Also provided herein are antibodies or antigen-binding
fragments thereof, that specifically recognize active forms of LOX
or LOXL2, methods for generating antibodies against active forms of
LOX or LOXL2, and method of using the antibodies to treat abnormal
cell proliferation, angiogenesis and fibrosis.
I. General Definitions
[0112] Unless defined otherwise, all technical and scientific terms
used herein have the same meaning as is commonly understood by one
of ordinary skill in the art to which this invention belongs. All
patents, applications, published applications and other
publications referred to herein are incorporated by reference in
their entirety. If a definition set forth in this section is
contrary to or otherwise inconsistent with a definition set forth
in the patents, applications, published applications and other
publications that are herein incorporated by reference, the
definition set forth in this section prevails over the definition
that is incorporated herein by reference. The headings provided
herein are for convenience only and do not limit the invention in
any way.
[0113] As used herein, "a" or "an" means "at least one" or "one or
more."
[0114] The phrase "conservative amino acid substitution" refers to
grouping of amino acids on the basis of certain common properties.
A functional way to define common properties between individual
amino acids is to analyze the normalized frequencies of amino acid
changes between corresponding proteins of homologous organisms
(Schulz, G. E. and R. H. Schirmer, Principles of Protein Structure,
Springer-Verlag). According to such analyses, groups of amino acids
may be defined where amino acids within a group exchange
preferentially with each other, and therefore resemble each other
most in their impact on the overall protein structure (Schulz, G.
E. and R. H. Schirmer, Principles of Protein Structure,
Springer-Verlag). Examples of amino acid groups defined in this
manner include: [0115] (i) a charged group, consisting of Glu and
Asp, Lys, Arg and His, [0116] (ii) a positively-charged group,
consisting of Lys, Arg and His, [0117] (iii) a negatively-charged
group, consisting of Glu and Asp, [0118] (iv) an aromatic group,
consisting of Phe, Tyr and Trp, [0119] (v) a nitrogen ring group,
consisting of His and Trp, [0120] (vi) a large aliphatic non-polar
group, consisting of Val, Leu and Ile, [0121] (vii) a
slightly-polar group, consisting of Met and Cys, [0122] (viii) a
small-residue group, consisting of Ser, Thr, Asp, Asn, Gly, Ala,
Glu, Gln and Pro, [0123] (ix) an aliphatic group consisting of Val,
Leu, Ile, Met and Cys, and [0124] (x) a small hydroxyl group
consisting of Ser and Thr.
[0125] In addition to the groups presented above, each amino acid
residue may form its own group, and the group formed by an
individual amino acid may be referred to simply by the one and/or
three letter abbreviation for that amino acid commonly used in the
art as described above.
[0126] A "conserved residue" is an amino acid that is relatively
invariant across a range of similar proteins. Often conserved
residues will vary only by being replaced with a similar amino
acid, as described above for "conservative amino acid
substitution".
[0127] The letter "x" or "xaa" as used in amino acid sequences
herein is intended to indicate that any of the twenty standard
amino acids may be placed at this position unless specifically
noted otherwise. For the purposes of peptidomimetic design, an "x"
or an "xaa" in an amino acid sequence may be replaced by a mimic of
the amino acid present in the target sequence, or the amino acid
may be replaced by a spacer of essentially any form that does not
interfere with the activity of the peptidomimetic.
[0128] "Homology" or "identity" or "similarity" refers to sequence
similarity between two peptides or between two nucleic acid
molecules. Homology and identity can each be determined by
comparing a position in each sequence which may be aligned for
purposes of comparison. When an equivalent position in the compared
sequences is occupied by the same base or amino acid, then the
molecules are identical at that position; when the equivalent site
occupied by the same or a similar amino acid residue (e.g., similar
in steric and/or electronic nature), then the molecules can be
referred to as homologous (similar) at that position. Expression as
a percentage of homology/similarity or identity refers to a
function of the number of identical or similar amino acids at
positions shared by the compared sequences. A sequence which is
"unrelated" or "non-homologous" shares less than 40% identity,
though preferably less than 25% identity with a sequence of the
present invention. In comparing two sequences, the absence of
residues (amino acids or nucleic acids) or presence of extra
residues also decreases the identity and homology/similarity.
[0129] The term "homology" describes a mathematically based
comparison of sequence similarities which is used to identify genes
or proteins with similar functions or motifs. The nucleic acid
(nucleotide, oligonucleotide) and amino acid (protein) sequences of
the present invention may be used as a "query sequence" to perform
a search against public databases to, for example, identify other
family members, related sequences or homologs. Such searches can be
performed using the NBLAST and XBLAST programs (version 2.0) of
Altschul, et al. (1990) J. Mol. Biol. 215:403-10. BLAST nucleotide
searches can be performed with the NBLAST program, score=100,
wordlength=12 to obtain nucleotide sequences homologous to nucleic
acid molecules of the invention. BLAST amino acid searches can be
performed with the XBLAST program, score=50, wordlength=3 to obtain
amino acid sequences homologous to protein molecules of the
invention. To obtain gapped alignments for comparison purposes,
Gapped BLAST can be utilized as described in Altschul et al.,
(1997) Nucleic Acids Res. 25(17):3389-3402. When utilizing BLAST
and Gapped BLAST programs, the default parameters of the respective
programs (e.g., XBLAST and BLAST) can be used (see,
ncbi.nlm.nih.gov).
[0130] As used herein, "identity" means the percentage of identical
nucleotide or amino acid residues at corresponding positions in two
or more sequences when the sequences are aligned to maximize
sequence matching, i.e., taking into account gaps and insertions.
Identity can be readily calculated by known methods, including but
not limited to those described in Computational Molecular Biology,
Lesk, A. M., ed., Oxford University Press, New York, 1988;
Biocomputing: Informatics and Genome Projects, Smith, D. W., ed.,
Academic Press, New York, 1993; Computer Analysis of Sequence Data,
Part I, Griffin, A. M., and Griffin, H. G., eds., Humana Press, New
Jersey, 1994; Sequence Analysis in Molecular Biology, von Heinje,
G., Academic Press, 1987; and Sequence Analysis Primer, Gribskov,
M. and Devereux, J., eds., M Stockton Press, New York, 1991; and
Carillo, H., and Lipman, D., SIAM J. Applied Math., 48: 1073
(1988). Methods to determine identity are designed to give the
largest match between the sequences tested. Moreover, methods to
determine identity are codified in publicly available computer
programs. Computer program methods to determine identity between
two sequences include, but are not limited to, the GCG program
package (Devereux, J., et al., Nucleic Acids Research 12(1): 387
(1984)), BLASTP, BLASTN, and FASTA (Altschul, S. F. et al., J.
Molec. Biol. 215: 403-410 (1990) and Altschul et al. Nuc. Acids
Res. 25: 3389-3402 (1997)). The BLAST X program is publicly
available from NCBI and other sources (BLAST Manual, Altschul, S.,
et al., NCBI NLM NIH Bethesda, Md. 20894; Altschul, S., et al., J.
Mol. Biol. 215: 403-410 (1990). The well known Smith Waterman
algorithm may also be used to determine identity.
[0131] The term "substantially identical" means identity between a
first amino acid sequence that contains a sufficient or minimum
number of amino acid residues that are i) identical to, or ii)
conservative substitutions of aligned amino acid residues in a
second amino acid sequence such that the first and second amino
acid sequences can have a common structural domain and/or common
functional activity. For example, amino acid sequences
substantially identical to LOX contain a common structural domain
having at least about 60%, or 65% identity, likely 75% identity,
more likely 85%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98% or 99%
identity to LOX. For example, amino acid sequences that contain a
common structural domain having at least about 60%, or 65%
identity, likely 75% identity, more likely 85%, 90%, 91%, 92%, 93%,
94%, 95%, 96%, 97%, 98% or 99% identity to LOXL2 are termed
sufficiently or substantially identical. In the context of
nucleotide sequence, the term "substantially identical" is used
herein to refer to a first nucleic acid sequence that contains a
sufficient or minimum number of nucleotides that are identical to
aligned nucleotides in a second nucleic acid sequence such that the
first and second nucleotide sequences encode a polypeptide having
common functional activity, or encode a common structural
polypeptide domain or a common functional polypeptide activity. For
example, nucleotide sequences having at least about 60%, or 65%
identity, likely 75% identity, more likely 85%, 90%, 91%, 92%, 93%,
94%, 95%, 96%, 97%, 98% or 99% identity to nucleic acid sequences
provided herein are termed substantially identical.
II. Lysyl Oxidase (LOX) and Lysyl Oxidase-Like (LOXL) Proteins
[0132] Typically, solid tumors contain areas of low oxygen tension
(hypoxia). Hypoxic cells present a great problem in the treatment
of cancer because these cells are highly aggressive, metastatic and
resistant to therapy. The underlying mechanisms contributing to
these features are poorly understood. Metastasis poses a particular
problem in breast cancer because there is no effective treatment
for the majority of patients with detectable metastatic breast
cancer (Steeg, P S. Br. Can. Res. 2(6): 396-9 (2000)).
[0133] The extracellular matrix (ECM) can have a major influence on
tumor cells (Chang and Werb. Trends Cell. Biol. 11: S37-43 (2001);
and Radisky et al. Semin. Cancer Bio. 11: 87-95 (2001)). Mice
exposed to hypoxia exhibit tissue specific increases in lysyl
oxidase (LOX) activity, an amine oxidase that plays an essential
role in the formation and maintenance of the ECM (Brody et al. Am.
Rev. Respir. Dis. 120: 1289-95 (2001)). A recent microarray study
confirmed LOX to be a hypoxia-induced gene in a variety of cell
lines (Denko, N C. Oncogene 22: 5907-14 (2003)). However, a
biological role of LOX under hypoxic conditions was not identified.
LOX initiates the covalent cross-linking of collagens and elastin
in the ECM, increasing insoluble matrix deposition and tensile
strength (Kagan and Li. J. Cell. Biochem. 88: 660-72 (2003)). LOX
expression is essential for wound healing and normal connective
tissue function, and knock-out mice die soon after parturition due
to cardiovascular instability (Hornstra et al. J. Biol. Chem. 278:
14387-93 (2003)). Decreased LOX activity is associated with
diseases such as Ehler-Danlos syndrome (Pinnell, S R. J. Invest.
Dermatol. 79(Supp 1): 90S-92S (1982); Royce et al. Biochem. J. 192:
579-86 (1980); and Khakoo et al. Clin. Genet. 51: 109-14 (1997)).
Increased LOX activity contributes to fibrotic and tissue
remodeling diseases, such as liver cirrhosis (Kagan, H M. Pathol.
Res. Pract. 190: 910-0 (1994); Chanki et al. Br. J. Dermatol. 133:
710-5 (1995); and Ooshima and Midorikawa. Jpn. Circ. J. 41: 1337-40
(1977)).
[0134] Elevated expression of LOX correlates with increased staging
in renal cell cancer (Stassar et al. Br. J. Cancer, 85: 1372-82
(2001)), and increased LOX expression is observed in highly
metastatic and/or invasive breast cancer cell lines (Kirschmann et
al. Breast Cancer Res. Treat. 55: 127-36 (1999); and Kirschmann et
al. Cancer Res. 62: 4478-83 (2002)). In contrast. LOX acts as a
tumor suppressor in non-tumorgenic revertants of ras-transformed
fibroblasts (Smith-Mungo and Kagan. Matrix Biol. 16: 387-98
(1998)). Loss of LOX is associated with tumorigenesis in several
cancer types such as gastric, colon and prostate cancers (Ren et
al. Cancer Res. 58: 1285-90 (1998); Cxiszar et al. Int. J. Cancer
97: 636-42 (2002); and Kaneda et al. Cancer Res. 64: 6410-5
(2004)). It would, thus, seem that LOX's tumor suppressive role
depends on cell type and transformation status. The propeptide
domain (and not the active enzyme) was recently shown to be
responsible for the tumor suppressor activities. In breast cancer,
increased LOX expression is associated with the early stromal
reaction (Decitre et al. Lab. Invest. 78: 143-51 (1998)), and
treatment with antisense LOX in this cancer cell type prevents in
vitro invasion (Kirschmann et al. Cancer Res. 62: 4478-83
(2002)).
[0135] The amino acid sequence of LOXL2 shares extensive sequence
homology with the conserved copper-binding and catalytic domains of
both LOX and LOXL. These conserved domains are encoded by five
consecutive exons within the LOX, LOXL, and LOXL2 genes that also
maintain exon-intron structure conservation. Conservation of the
nucleotide and deduced amino acid sequence within the
carboxyl-terminal end of LOXL2, LOX, and LOXL include the
copper-binding domain (WEWHSCHQHYH (SEQ ID NO: 66)) in LOX and LOXL
and WIWHDCHRHYH (SEQ ID NO: 67) in LOXL2 with the four histidines
that supply the nitrogen ligands for the copper coordination
complex specific for lysyl oxidase proteins (Krebs and Krawetz,
Biochim. Biophys. Acta 1202: 7-12 (1993)). The active site in LOX
(DIDCQWVDITDVPPPGDY (SEQ ID NO: 68)) and in LOXL2
(DIDCQWVDITDVPPPGDY (SEQ ID NO: 69)) contains, in each, a Tyr
residue (Y) at the COOH-terminal end, which participates together
with a Lys residue in the formation of the quinone co-factor that
is present in these proteins. Ten cysteines characteristic of LOX
and LOXL are similarly conserved in LOXL2 (Kagan et al., (1994) in
Molecular Biology and Pathology of Elastic Tissue (Mecham, R. P.,
and Roberts, L., eds), Ciba Foundation Symposium Series, Wiley,
Chichester, UK). A growth factor and cytokine receptor domain
present in the LOX and LOXL proteins has also been identified
within the LOXL2-derived amino acid sequence. Four repeats of the
scavenger receptor cysteine-rich domain are also present of LOXL2
(Saito et al., J. Biol. Chem. 272: 8157-8160 (1997), Resnick et
al., Trends Biochem. Sci. 19: 5-8 (1994)).
[0136] Three major transcription termination sites have been noted
within 3'-UTR domains of LOXL2 cDNA. The first termination site is
690 bp 3' of the termination codon, the second site is 740 bp, and
the final transcription termination site is 900 bp 3' of the
termination codon. These mRNAs all have 3'-UTRs differing slightly
in size. Most exon-intron boundaries of the LOXL2 gene show the
consensus sequence (C/T)AG-exon-GT(A/G). The sizes of the 11 exons
of the LOXL2 gene range from 112 to 940 bp. Although the LOXL2 gene
has 11 exons, five consecutive exons (exons 6-10), which encode the
copper-binding and catalytic domains, exhibit 84% sequence
similarity, and exon sizes are very similar to the corresponding
exons of the LOX and LOXL genes. All the other exons in the LOXL2
gene are divergent in both sequence and size. LOXL2 has been
identified in all tissues with the exception of blood leukocytes.
LOXL2 mRNA has been detected in heart, liver, and pancreas;
expression is significantly higher in placenta, prostate, uterus,
and pancreas (ratios between 2 and 3) compared with lower
expression in brain, lung, skeletal muscle, thymus, and kidney
(ratios below 0.5). (Jourdan-Le Saux, et al. J. Biol. Chem.,
274(18): 12939-12944 (1999)).
[0137] The expression of LOX and the different LOXL proteins varies
in different diseases. This may be due to a number of reasons, such
as the difference in tissue distribution, processing, domains,
regulation of activity, as well as other differences between the
proteins. For example, LOX and LOXL are implicated in fibrotic
diseases as both LOX and LOXL are highly expressed in
myo-fibroblasts around fibrotic areas (Kagen, Pathol. Res. Pract.
190:910-919 (1994); Murawaki et al., Hepatology 14:1167-1173
(1991); Siegel et al., Proc. Natl. Acad. Sci. USA 75:2945-2949
(1978); Jourdan Le-Saux et al., Biochem. Biophys. Res. Comm.
199:587-592 (1994); Kim et al., J. Cell Biochem. 72:181-188
(1999)). LOX and the various LOXL are also implicated in a number
of cancers. For example, LOXL and LOXL4 have been shown to be
epigenetically silenced and can inhibit ras/extracellular
signal-regulated kinase signaling pathway in human bladder cancer
(Wu et al., Cancer Res. 67:4123-4129 (2007)). Others have shown
selective upregulation and amplification of the LOXL4 gene in head
and neck squamous cell carcinoma (Gorough et al., J. Pathol.
212:74-82 (2007)). LOX and LOXL2 have also been implicated in a
number of tumors, such as colon and esophageal cancers (Csiszar,
Prog. Nucl. Acid Res. 70:1-32 (2001)). In breast cancer, LOX and
the LOXL family members have been linked to the cancer (Kirschmann
et al., Cancer Res. 62:448-4483 (2002)).
[0138] Lysyl oxidase catalyzes oxidative deamination of peptidyl
lysine and hydroxylysine residues in collagens, and peptidyl lysine
residues in elastin. The resulting peptidyl aldehydes spontaneously
condense and undergo oxidation reactions to form the lysine-derived
covalent cross-links required for the normal structural integrity
of the extracellular matrix. In the reaction of lysyl oxidase with
its substrates, hydrogen peroxide (H2O2) and ammonium are released
in quantities stoichiometric with the peptidyl aldehyde product.
See, e.g., Kagan et al., J. Cell. Biochem. 88:660-72 (2003).
[0139] Lysyl oxidase is secreted into the extracellular environment
where it is then processed by proteolytic cleavage to a functional
30 kDa enzyme and an 18 kDa propeptide. The 30 kDa lysyl oxidase is
enzymatically active whereas the 50 kDa proenzyme is not.
Procollagen C-proteinases process pro-lysyl oxidase to its active
form and are products of the Bmp1, TII1 and TII2 genes. The
localization of the enzyme is mainly extracellular, although
processed lysyl oxidase also localizes intracellularly and
nuclearly. Sequence coding for the propeptide is moderately
(60-70%) conserved among LOX and the LOXL proteins, whereas the
sequence coding for the C-terminal 30 kDa region of the proenzyme
in which the active site is located is highly conserved
(approximately 95%). See Kagan et al., J. Cell Biochem. 59:329-38
(1995). LOX is induced by a number of growth factors and steroids
such as TGF-.beta., TNF-.alpha. and interferon (Csiszar, Prog.
Nucl. Acid Res. 70:1-32 (2001)).
[0140] Five different lysyl oxidases are known to exist in both
humans and mice, LOX and four LOX related, or LOX-like proteins
(LOXL, LOXL2, LOXL3, LOXL4). LOX and the LOX-like proteins are
referred to collectively as "LOX/LOXL" for the purposes of the
present disclosure. The five forms of lysyl oxidases reside on five
different chromosomes. These family members show some overlap in
structure and function, but appear to have distinct functions as
well. For example, although the main activity of LOX is the
oxidation of specific lysine residues in collagen and elastin
outside of the cell, it may also act intracellularly, where it may
regulate gene expression. In addition, LOX induces chemotaxis of
monocytes, fibroblasts and smooth muscle cells. Further, a deletion
of LOX in knockout mice appears to be lethal at parturition
(Hornstra et al., J. Biol. Chem. 278:14387-14393 (2003)), whereas
LOXL deficiency causes no severe developmental phenotype (Bronson
et al., Neurosci. Lett. 390:118-122 (2005)).
[0141] The main activity of LOX is the oxidation of specific lysine
residues in collagen and elastin outside of the cell, however, it
may also act intracellularly, where it may regulate gene expression
(Li et al., Proc. Natl. Acad. Sci. USA 94:12817-12822 (1997),
Giampuzzi et al., J. Biol. Chem. 275:36341-36349 (2000)) In
addition, LOX induces chemotaxis of monocytes, fibroblasts and
smooth muscle cells (Lazarus et al., Matrix Biol. 14:727-731 (1995)
Nelson et al., Proc. Soc. Exp. Biol. Med. 188:346-352 (1988)). LOX
itself is induced by a number of growth factors and steroids such
as TGF-.beta., TNF-.alpha. and interferon (Csiszar, Prog. Nucl.
Acid Res. 70:1-32 (2001)). Recent studies have attributed other
roles to LOX in diverse biological functions such as developmental
regulation, tumor suppression, cell motility, and cellular
senescence. The diverse role of LOX, and its recently discovered
amino oxidase family, LOX-like (LOXL), may play important roles
with their intracellular and extracellular localization.
[0142] As used herein, the term "lysyl oxidase" refers to an enzyme
that catalyzes the following reaction:
peptidyl-L-lysyl-peptide+O2+H2O.fwdarw.peptidyl-allysyl-peptide+NH3+H2O2.
Other synonyms for lysyl oxidase (EC 1.4.3.13) include
protein-lysine 6-oxidase and protein-L-lysine:oxygen
6-oxidoreductase (deaminating). See, e.g., Harris et al., Biochim.
Biophys. Acta 341:332-44 (1974); Rayton et al., J. Biol. Chem.
254:621-26 (1979); Stassen, Biophys. Acta 438:49-60 (1976). A
copper-containing quinoprotein with a lysyl adduct of tyrosyl
quinone at its active center, LOX catalyzes the oxidation of
peptidyl lysine to result in the formation of peptidyl
alpha-aminoadipic-delta-semialdehyde. Once formed, this
semialdehyde can spontaneously condense with neighboring aldehydes
or with other lysyl groups to from intra-and interchain
cross-links. See, e.g., Rucker et al., Am. J. Clin. Nutr.
67:996S-1002S (1998).
[0143] The term "LOX" refers to an enzyme having an amino acid
sequence substantially identical to a polypeptide expressed or
translated from one of the following sequences: EMBL/GenBank
accession numbers: M94054 (SEQ ID NO: 10); AAA59525.1 (SEQ ID NO:
11)--mRNA; S45875 (SEQ ID NO: 12); AAB23549.1 (SEQ ID NO:
13)--mRNA; S78694 (SEQ ID NO: 14); AAB21243.1 (SEQ ID NO:
15)--mRNA; AF03929 I (SEQ ID NO: 16); AAD02130.1 (SEQ ID NO:
17)--mRNA; BC074820 (SEQ ID NO: 18); AAH74820.1 (SEQ ID NO:
19)--mRNA; BC074872 (SEQ ID NO: 20); AAH74872.1 (SEQ ID NO:
21)--mRNA; M84150 (SEQ ID NO: 22); AAA59541.1 (SEQ ID NO:
23)--Genomic DNA. One embodiment of LOX is human lysyl oxidase
(hLOX) preproprotein having an amino acid sequence (SEQ ID NO: 7),
a secreted hLOX after cleavage of the signal peptide such as SEQ ID
NO: 8 or a mature hLOX after proteolytic processing such as SEQ ID
NO: 9.
[0144] LOX has highly conserved protein domains, conserved in
several species including human, mouse, rat, chicken, fish and
Drosophila. The human LOX family has a highly conserved C-terminal
region containing the 205 amino acid LOX catalytic domain. The
conserved region contains the copper binding (Cu), conserved
cytokine receptor like domain (CRL), and the lysyl-tyrosylquinone
cofactor site (LTQ). The predicted extracellular signal sequences
are represented by the hatched boxes (See FIG. 7 of U.S.
Provisional Application No. 60/963,249, which is incorporated
herein by reference). Twelve cysteine residues are also similarly
conserved, wherein two of them reside within the prepropeptide
region and ten are in the catalytically active processed form of
LOX (Csiszar, Prog. Nucl. Acid Res. 70:1-32 (2001)). The conserved
region also includes a fibronectin binding domain.
[0145] The prepropeptide region of LOX contains the signal peptide,
and is cleaved, the cleavage site predicted to be between
Cys21-Ala22, to generate a signal sequence peptide and a 48 kDa
amino acid propeptide form of LOX, which is still inactive. The
propeptide is N-glycosylated during passage through the Golgi that
is secreted into the extracellular environment where the proenzyme,
or propeptide, is cleaved between Gly168-Asp169 by a
metalloendoprotease, a procollagen C-proteinase, which are products
of the Bmp1, TII1 and TII2 genes. BMP I (bone morphogenetic protein
I) is a procollagen C-proteinase that processes the propeptide to
yield a functional 30 kDa enzyme and an 18 kDa propeptide. The
sequence coding for the propeptide is moderately (60-70%)
conserved, whereas the sequence coding for the C-terminal 30 kDa
region of the proenzyme in which the active site is located is
highly conserved (approximately 95%). (Kagan and Li, J. Cell.
Biochem. 88:660-672 (2003); Kagan et al., J. Cell Biochem.
59:329-38 (1995)). The N-glycosyl units are also subsequently
removed. LOX occurs in unprocessed and/or processed (mature) forms.
The mature form of LOX is typically active although, in some
embodiments, unprocessed LOX is also active.
[0146] Particular examples of a LOXL enzyme or protein are
described in Molnar et al., Biochim Biophys Acta. 1647:220-24
(2003); Csiszar, Prog. Nucl. Acid Res. 70:1-32 (2001); and in WO
01/83702 published on Nov. 8, 2001, all of which are herein
incorporated by reference. (It is noted that in these 3
publications, "LOXL1" was referred to as "LOXL" whereas in the
present invention "LOXL" is used to refer to a lysyl oxidase-like
proteins in general, not just LOXL1.) These enzymes include LOXL1,
encoded by mRNA deposited at GenBank/EMBL BC015090; AAH15090.1;
LOXL2, encoded by mRNA deposited at GenBank/EMBL U89942; LOXL3,
encoded by mRNA deposited at GenBank/EMBL AF282619; AAK51671.1; and
LOXL4, encoded by mRNA deposited at GenBank/EMBL AF338441;
AAK71934.1.
[0147] Similar potential signal peptides as those described above
for LOX have been predicted at the amino terminus of LOXL, LOXL2,
LOXL3, and LOXL4. The predicted signal cleavage sites are between
Gly25-Gln26 for LOXL, between Ala25-Gln26, for LOXL2, and between
Gly25-Ser26 for LOXL3. The consensus for BMP-1 cleavage in
pro-collagens and pro-LOX is between Ala/Gly-Asp, and often
followed by an acidic or charged residue. A potential cleavage site
to generate active LOXL is Gly303-Asp304, however, it is then
followed by an atypical Pro. LOXL3 also has a potential cleavage
site at Gly447-Asp448, which is followed by an Asp, processing at
this site may yield an active peptide of similar size to active
LOX. A potential cleavage site of BMP-I was also identified within
LOXL4, at residues Ala569-Asp570 (Kim et al., J. Biol. Chem.
278:52071-52074 (2003)). LOXL2 may also be proteolytically cleaved
analogously to the other members of the LOXL family and secreted
(Akiri et al., Cancer Res. 63:1657-1666 (2003)).
[0148] LOX and LOXL enzymes act via a ping-pong mechanism which can
be described by Michaelis-Menten kinetics (see FIG. 1).
[0149] An example of LOX or LOXL protein include the enzyme having
an amino acid sequence substantially identical to a polypeptide
expressed or translated from one of the following sequences :
EMBL/GenBank accessions: M94054; AAA59525.1--mRNA; S45875;
AAB23549.1--mRNA; S78694; AAB21243.1--mRNA; AF039291;
AAD02130.1--mRNA; BC074820; AAH74820.1--mRNA; BC074872;
AAH74872.1--mRNA; M84150; AAA59541.1--Genomic DNA.
[0150] The terms "LOX" and "LOXL" also encompass functional
fragments or derivatives that substantially retain enzymatic
activity catalyzing the deamination of lysyl residues. Typically, a
functional fragment or derivative retains at least 50% of 60%, 70%,
80%, 90%, 95%, 99% or 100% of its lysyl oxidation activity. It is
also intended that a LOX or a LOXL2 protein can include
conservative amino acid substitutions that do not substantially
alter its activity. Suitable conservative substitutions of amino
acids are known to those of skill in this art and may be made
generally without altering the biological activity of the resulting
molecule. Those of skill in this art recognize that, in general,
single amino acid substitutions in non-essential regions of a
polypeptide do not substantially alter biological activity. See,
e.g., Watson, et al., Molecular Biology of the Gene, 4th Edition,
1987, The Benjamin/Cummings Pub. Co., p. 224. Conservative and
non-conservative amino acid substitutions have been described
above.
[0151] A feature not known to be common amongst the LOX and LOXL
proteins is the scavenger receptor cysteine rich (SRCR) domains.
LOX and LOXL lack SRCR domains, whereas LOXL2, LOXL3, and LOXL4
each have four SRCR domains at the N-terminus. SRCR domains are
found in secreted, transmembrane, or extracellular matrix proteins.
SRCR domains are also known to mediate ligand binding in a number
of secreted and receptor proteins (Hoheneste et al., Nat. Struct.
Biol. 6:228-232 (1999); Sasaki et al., EMBO J. 17:1606-1613
(1998)). Another domain unique to LOXL is the presence of a proline
rich domain (Molnar et al., Biochimica Biophsyica Acta 1647:220-224
(2003)).
[0152] Tissue distribution may also differ amongst LOX and the
various LOXL. LOX is highly expressed in the heart, placenta,
testis, lung, kidney and uterus, but marginally in the brain and
liver. LOXL I is expressed in the placenta, kidney, muscle, heart,
lung, and pancreas, and as with LOX, has much lower expressing in
the brain and liver (Kim et al., J. Biol. Chem. 270:7176-7182
(1995)). LOXL2 is highly expressed in the uterus, placenta, and
other organs, but similar to LOX and LOXL, lowly expressed in the
brain and liver (Jourdan Le-Saux et al., J. Biol. Chem.
274:12939:12944 (1999)). LOXL3 is highly expressed in the testis,
spleen, and prostate, moderately in placenta, and not in the liver,
whereas LOXL4 is highly expressed in the liver (Huang et al.,
Matrix Biol. 20:153-157 (2001); Maki and Kivirikko, Biochem. J.
355:381-387 (2001); Jourdan Le-Saux et al., Genomics 74:211-218
(2001); Asuncion et al., Matrix Biol. 20:487-491 (2001)).
[0153] The expression, or implication of LOX and the different LOXL
proteins, in diseases may also vary. This may be due to a number of
reasons, such as the difference in tissue distribution, processing,
domains, regulation of activity, as well as other differences
between the proteins. For example, LOX and LOXL are implicated in
fibrotic diseases as both LOX and LOXL are highly expressed in
myo-fibroblasts around fibrotic areas (Kagen, Pathol. Res. Pract.
190:910-919 (1994); Murawaki et al., Hepatology 14:1167-1173
(1991); Siegel et al., Proc. Natl. Acad. Sci. USA 75:2945-2949
(1978); Jourdan Le-Saux et al., Biochem. Biophys. Res. Comm.
199:587-592 (1994); Kim et al., J. Cell Biochem. 72:181-188
(1999)). LOX and the various LOXL are also implicated in a number
of cancers. For example, LOXL and LOXL4 have been shown to be
epigenetically silenced and can inhibit ras/extracellular
signal-regulated kinase signaling pathway in human bladder cancer
(Wu et al., Cancer Res. 67:4123-4129 (2007)). Others have shown
selective upregulation and amplification of the LOXL4 gene in head
and neck squamous cell carcinoma (Gorough et al., J. Pathol.
212:74-82 (2007)). LOX and LOXL2 have also been implicated in a
number of tumors, such as colon and esophageal cancers (Csiszar,
Prog. Nucl. Acid Res. 70:1-32 (2001)). In breast cancer, LOX and
the LOXL family members have been linked to the cancer (Kirschmann
et al., Cancer Res. 62:448-4483 (2002)).
III. Epithelial--Mesenchymal Transition
[0154] Epithelial-to-Mesenchymal Transition (EMT) refers to the
process whereby a cell with a gene expression/phenotype
characteristic of epithelial cell (i.e., expressing specific
proteins, factors, and molecules) changes or alters the genes or
their level of expression which results in a change in the
phenotype of the cell as exhibited by the alteration or change in
the genes expressed.
[0155] Epithelial and mesenchymal cells represent distinct
lineages, each with a unique gene expression profile that imparts
attributes specific to each cell type. Conversion of an epithelial
cell into a mesenchymal cell requires alterations in morphology,
cellular architecture, adhesion, and/or migration capacity.
Advanced tumor cells frequently exhibit a conspicuous
down-regulation of epithelial markers and a loss of intercellular
junctions, resulting in a loss of epithelial polarity and reduced
intercellular adhesion. The loss of epithelial features is often
accompanied by increased cell motility and expression of
mesenchymal genes. EMT can include loss of contact inhibition,
altered growth control, and/or enhanced invasiveness (Christiansen
and Rajasekaran, Cancer Res., 66(17): 8319-8326 (2006); and Thiery
et al., Curr. Opin. Cell. Biol., 15: 740-6 (2003)). Molecular and
morphologic features indicative of EMT correlate with poor
histologic differentiation, destruction of tissue integrity, and
metastasis. EMT provides mechanisms for epithelial cells to
overcome the physical constraints imposed on them by intercellular
junctions and adopt a motile phenotype (Burdsal et al. Development,
118:829-44 (1993); and Nieto et al., Mech, Dev., 105:27-35
(2001)).
[0156] Commonly used molecular markers for EMT include increased
expression of N-cadherin and vimentin, nuclear localization of
.beta.-catenin, and increased production of the transcription
factors such as Snail1 (Snail), Snail2 (Slug), Twist, EF1/ZEB1,
SIP1/ZEB2, and/or E47 that inhibit E-cadherin production.
Phenotypic Markers for an EMT include, but are not limited to, an
increased capacity for migration and three-dimensional invasion, as
well as resistance to apoptosis. These markers have further been
correlated with induction of EMT and an association with cancerous
phenotypes.
[0157] The occurrence of EMT during tumor progression allows tumor
cells to acquire the capacity to infiltrate surrounding tissue and
ultimately to metastasize to distant sites. Changes in gene
expression within tumor cells can indicate a progression from
epithelial or epithelial-like gene expression pattern to a
mesenchymal or mesenchymal-like gene expression pattern. By way of
example, the identification of loss of E-cadherin is correlated
with metastatic carcinoma as well as resistance to cancer therapies
such as EGFR inhibitors and IGF-R1 inhibitors. Analysis of many
different types of cancer reveals that circulating tumor cells, or
those found as micrometastases, evidence mesenchymal conversion
based on changes of expression in a set of markers. These markers
include, but are not limited to, EGFR, E-cadherin, ErbB3, RAB25,
integrin beta 6, cadherin-2, fibroblast growth factor binding
protein I, distal-less homeo box 1, ZEB1 (transcription factor 8),
SIP1, and vimentin.
[0158] By way of example, an epithelial-like gene expression
profile includes expression, or increase expression of genes such
as E-cadherin, ErbB3, or EGFR. An epithelial-like gene expression
profile can include the expression of one or more of these genes,
at least two, or at least three of these genes.
[0159] As with the previously described therapy-resistant cancers,
the expression levels of E-cadherin, ErbB3, RAB25, integrin beta 6,
cadherin-2, fibroblast growth factor binding protein 1, distal-less
homeo box 1, ZEB1 (transcription factor 8), SIP1,TGF-.beta., FOXC2,
GSK-313, Smad-3, Pez, Snail1, Snail2, and ILK, and vimentin
represent genes that are common to EMT characteristics as well as
with those epithelial-based tumor cells/cancers that develop
resistance to their respective therapies. The present invention
also generally relates to a method to treat a patient with cancer,
and particularly a cancer that has experienced EMT. The inventors
have discovered that cancers that have experienced EMT or have
switched from an epithelial-like gene expression pattern to a
mesenchymal-like gene expression pattern are responsive to LOX/LOXL
inhibitors.
[0160] For assessment of tumor cell epithelial or mesenchymal
biomarker expression, patient samples containing tumor cells, or
proteins or nucleic acids produced by these tumor cells, can be
used in methods described, for example, in U.S. patent application
Publication Number 20070065858, which is incorporated in its
entirety by reference herein. Briefly, the level of expression of
the biomarker can be assessed by assessing the amount (e.g.,
absolute amount or concentration) of the marker in a tumor cell
sample, e.g., a tumor biopsy obtained from a patient, or other
patient sample containing material derived from the tumor (e.g.,
blood, serum, urine, or other bodily fluids or excretions as
described herein above). The cell sample can, of course, be
subjected to a variety of well-known post-collection preparative
and storage techniques (e.g., nucleic acid and/or protein
extraction, fixation, storage, freezing, ultrafiltration,
concentration, evaporation, centrifugation, etc.) prior to
assessing the amount of the marker in the sample. Likewise, tumor
biopsies can also be subjected to post-collection preparative and
storage techniques, e.g., fixation.
[0161] One can detect expression of biomarker proteins having at
least one portion which is displayed on the surface of tumor cells
which express it. It is a simple matter for the skilled artisan to
determine whether a marker protein, or a portion thereof, is
exposed on the cell surface. For example, immunological methods can
be used to detect such proteins on whole cells, or well known
computer-based sequence analysis methods can be used to predict the
presence of at least one extracellular domain (i.e., including both
secreted proteins and proteins having at least one cell-surface
domain). Expression of a marker protein having at least one portion
which is displayed on the surface of a cell which expresses it can
be detected without necessarily lysing the tumor cell (e.g., using
a labeled antibody which binds specifically with a cell-surface
domain of the protein).
[0162] Expression of biomarkers can be assessed by any of a wide
variety of well known methods for detecting expression of a
transcribed nucleic acid or protein. Non-limiting examples of such
methods include, for example, immunological methods for detection
of secreted, cell-surface, cytoplasmic, or nuclear proteins,
protein purification methods, protein function or activity assays,
nucleic acid hybridization methods, nucleic acid reverse
transcription methods, and nucleic acid amplification methods.
[0163] Expression of a biomarker can be assessed using an antibody
(e.g., a radio-labeled, chromophore-labeled, fluorophore-labeled,
or enzyme-labeled antibody), an antibody derivative (e.g., an
antibody conjugated with a substrate or with the protein or ligand
of a protein-ligand pair (e.g., biotin-streptavidin), or an
antibody fragment (e.g., a single-chain antibody, an isolated
antibody hypervariable domain, etc.) which binds specifically with
a biomarker protein or fragment thereof, including a biomarker
protein which has undergone either all or a portion of
post-translational modifications to which it is normally subjected
in the tumor cell (e.g., glycosylation, phosphorylation,
methylation etc.).
[0164] Expression of a biomarker can also be assessed by preparing
mRNA/cDNA (i.e., a transcribed polynucleotide) from cells in a
patient sample, and by hybridizing the mRNA/cDNA with a reference
polynucleotide which is a complement of a biomarker nucleic acid,
or a fragment thereof. cDNA can, optionally, be amplified using any
of a variety of polymerase chain reaction methods prior to
hybridization with the reference polynucleotide. Expression of one
or more biomarkers can likewise be detected using quantitative PCR
to assess the level of expression of the biomarker(s).
Alternatively, any of the many known methods of detecting mutations
or variants (e.g., single nucleotide polymorphisms, deletions,
etc.) of a biomarker can be used to detect occurrence of a
biomarker in a patient.
[0165] A mixture of transcribed polynucleotides obtained from the
sample can be contacted with a substrate having fixed thereto a
polynucleotide complementary to or homologous with at least a
portion (e.g., at least 7, 10, 15, 20, 25, 30, 40, 50, 100, 500, or
more nucleotide residues) of a biomarker nucleic acid. If
polynucleotides complementary to, or homologous with, are
differentially detectable on the substrate (e.g., detectable using
different chromophores or fluorophores, or fixed to different
selected positions), then the levels of expression of a plurality
of biomarkers can be assessed simultaneously using a single
substrate (e.g., a "gene chip" microarray of polynucleotides fixed
at selected positions). When a method of assessing biomarker
expression is used which involves hybridization of one nucleic acid
with another, hybridization can be performed under stringent
hybridization conditions.
[0166] When a plurality of biomarkers of the invention are used in
the methods of the invention, the level of expression of each
biomarker in a patient sample can be compared with the normal level
of expression of each of the plurality of biomarkers in
non-cancerous samples of the same type, either in a single reaction
mixture (i.e., using reagents, such as different fluorescent
probes, for each biomarker) or in individual reaction mixtures
corresponding to one or more of the biomarkers.
[0167] The level of expression of a biomarker in normal (i.e.,
non-cancerous) human tissue can be assessed in a variety of ways.
This normal level of expression can be assessed by assessing the
level of expression of the biomarker in a portion of cells which
appears to be non-cancerous, and then comparing the normal level of
expression with the level of expression in a portion of the tumor
cells. As further information becomes available as a result of
routine performance of the methods described herein,
population-average values for normal expression of the biomarkers
can be used. Alternatively, the normal level of expression of a
biomarker can be determined by assessing expression of the
biomarker in a patient sample obtained from a non-cancer-afflicted
patient, from a patient sample obtained from a patient before the
suspected onset of cancer in the patient, from archived patient
samples, and the like.
[0168] An exemplary method for detecting the presence or absence of
a biomarker protein or nucleic acid in a biological sample involves
obtaining a biological sample (e.g., a tumor-associated body fluid)
from a test subject and contacting the biological sample with a
compound or an agent capable of detecting the polypeptide or
nucleic acid (e.g., mRNA, genomic DNA, or cDNA). The detection
methods can, thus, be used to detect mRNA, protein, cDNA, or
genomic DNA, for example, in a biological sample in vitro as well
as in vivo. In vitro techniques for detection of mRNA include, for
example, Northern hybridizations and in situ hybridizations. In
vitro techniques for detection of a biomarker protein include, but
are not limited to, enzyme linked immunosorbent assays (ELISAs),
Western blots, immunoprecipitation and immunofluorescence. In vitro
techniques for detection of genomic DNA include, for example,
Southern hybridizations. In vivo techniques for detection of mRNA
include, for example, polymerase chain reaction (PCR), Northern
hybridizations and in situ hybridizations. Furthermore, in vivo
techniques for detection of a biomarker protein include introducing
into a subject a labeled antibody directed against the protein or
fragment thereof. For example, the antibody can be labeled with a
radioactive marker whose presence and location in a subject can be
detected by standard imaging techniques.
[0169] A general principle of such diagnostic and prognostic assays
involves preparing a sample or reaction mixture that may contain a
biomarker, and a probe, under appropriate conditions and for a time
sufficient to allow the biomarker and probe to interact and bind,
thus forming a complex that can be removed and/or detected in the
reaction mixture. These assays can be conducted in a variety of
ways.
[0170] For example, one method to conduct such an assay involves
anchoring the biomarker or probe onto a solid phase support, also
referred to as a substrate, and detecting target biomarker/probe
complexes anchored on the solid phase at the end of the reaction.
In one embodiment of such a method, a sample from a subject, which
is to be assayed for presence and/or concentration of biomarker,
can be anchored onto a carrier or solid phase support. In another
embodiment, the reverse situation is possible, in which the probe
can be anchored to a solid phase and a sample from a subject can be
allowed to react as an unanchored component of the assay.
[0171] There are several established methods for anchoring assay
components to a solid phase. These include, without limitation,
biomarker or probe molecules which are immobilized through
conjugation of biotin and streptavidin. Such biotinylated assay
components can be prepared from biotin-NHS (N-hydroxy-succinimide)
using techniques known in the art (e.g., biotinylation kit, Pierce
Chemicals, Rockford, Ill.), and immobilized in the wells of
streptavidin-coated 96 well plates (Pierce Chemical). In certain
embodiments, the surfaces with immobilized assay components can be
prepared in advance and stored. Other suitable Carriers or solid
phase supports for such assays include any material capable of
binding the class of molecule to which the biomarker or probe
belongs. Well-known supports or carriers include, but are not
limited to, glass, polystyrene, nylon, polypropylene, nylon,
polyethylene, dextran, amylases, natural and modified celluloses,
polyacrylamides, gabbros, and magnetite. In order to conduct assays
with the above mentioned approaches, the non-immobilized component
is added to the solid phase upon which the second component is
anchored. After the reaction is complete, uncomplexed components
can be removed (e.g., by washing) under conditions such that any
complexes formed will remain immobilized upon the solid phase. The
detection of biomarker/probe complexes anchored to the solid phase
can be accomplished in a number of methods outlined herein. In one
embodiment, the probe, when it is the unanchored assay component,
can be labeled for the purpose of detection and readout of the
assay, either directly or indirectly, with detectable labels
discussed herein and which are well-known to one skilled in the
art.
[0172] It is also possible to directly detect biomarker/probe
complex formation without further manipulation or labeling of
either component (biomarker or probe), for example by utilizing the
technique of fluorescence energy transfer (i.e., FET, see for
example, Lakowicz et al., U.S. Pat. No. 5,631,169; Stavrianopoulos,
et al., U.S. Pat. No. 4,868,103). A fluorophore label on the first,
donor molecule is selected such that, upon excitation with incident
light of appropriate wavelength, its emitted fluorescent energy
will be absorbed by a fluorescent label on a second acceptor
molecule, which in turn is able to fluoresce due to the absorbed
energy. Alternately, the donor protein molecule can simply utilize
the natural fluorescent energy of tryptophan residues. Labels are
chosen that emit different wavelengths of light, such that the
acceptor molecule label can be differentiated from that of the
donor. Since the efficiency of energy transfer between the labels
is related to the distance separating the molecules, spatial
relationships between the molecules can be assessed. In a situation
in which binding occurs between the molecules, the fluorescent
emission of the acceptor molecule label in the assay should be
maximal. An FET binding event can be conveniently measured through
standard fluorometric detection means well known in the art (e.g.,
using a fluorimeter).
[0173] In another embodiment, determination of the ability of a
probe to recognize a biomarker can be accomplished without labeling
either assay component (probe or biomarker) by utilizing a
technology such as real-time Biomolecular Interaction Analysis
(BIA) (see, e.g., Sjolander, S. and Urbaniczky, C., 1991, Anal.
Chem. 63:2338-2345 and Szabo et al., 1995, Curr. Opin. Struct.
Biol. 5:699-705). As used herein, "BIA" or "surface plasmon
resonance" is a technology for studying biospecific interactions in
real time, without labeling any of the interactants (e.g.,
BIAcore). Changes in the mass at the binding surface (indicative of
a binding event) result in alterations of the refractive index of
light near the surface (the optical phenomenon of surface plasmon
resonance (SPR)), resulting in a detectable signal which can be
used as an indication of real-time reactions between biological
molecules.
[0174] Alternatively, in another embodiment, analogous diagnostic
and prognostic assays can be conducted with biomarker and probe as
solutes in a liquid phase. In such an assay, the complexed
biomarker and probe are separated from uncomplexed components by
any of a number of standard techniques, including but not limited
to: differential centrifugation, chromatography, electrophoresis
and immunoprecipitation. In differential centrifugation,
biomarker/probe complexes can be separated from uncomplexed assay
components through a series of centrifugal steps, due to the
different sedimentation equilibria of complexes based on their
different sizes and densities (see, for example, Rivas, G., and
Minton, A. P., 1993, Trends Biochem Sci. 18(8):284-7). Standard
chromatographic techniques can also be utilized to separate
complexed molecules from uncomplexed ones. For example, gel
filtration chromatography separates molecules based on size, and
through the utilization of an appropriate gel filtration resin in a
column format; for example, the relatively larger complex can be
separated from the relatively smaller uncomplexed components.
Similarly, the relatively different charge properties of the
biomarker/probe complex as compared to the uncomplexed components
can be exploited to differentiate the complex from uncomplexed
components, for example through the utilization of ion-exchange
chromatography resins. Such resins and chromatographic techniques
are well known to one skilled in the art (see, e.g., Heegaard, N.
H., 1998, J. Mol. Recognit. Winter 11(1-6):141-8; Hage, D. S., and
Tweed, S. A. J. Chromatogr B Biomed Sci Appl Oct. 10, 1997;
699(1-2):499-525). Gel electrophoresis can also be employed to
separate complexed assay components from unbound components (see,
e.g., Ausubel et al., ed., Current Protocols in Molecular Biology,
John Wiley & Sons, New York, 1987-1999). In this technique,
protein or nucleic acid complexes are separated based on size or
charge, for example. In order to maintain the binding interaction
during the electrophoretic process, non-denaturing gel matrix
materials and conditions in the absence of reducing agent are
typically used. Appropriate conditions to the particular assay and
components thereof will be well known to one skilled in the
art.
[0175] In another embodiment, the level of biomarker mRNA can be
determined both by in situ and by in vitro formats in a biological
sample using methods known in the art. The term "biological sample"
is intended to include tissues, cells, biological fluids and
isolates thereof, isolated from a subject, as well as tissues,
cells and fluids present within a subject. Many expression
detection methods use isolated RNA. For in vitro methods, any RNA
isolation technique that does not select against the isolation of
mRNA can be utilized for the purification of RNA from tumor cells
(see, e.g., Ausubel et al., ed., Current Protocols in Molecular
Biology, John Wiley & Sons, New York 1987-1999). Additionally,
large numbers of tissue samples can readily be processed using
techniques well known to those of skill in the art, such as, for
example, the single-step RNA isolation process of Chomczynski
(1989, U.S. Pat. No. 4,843,155).
[0176] The isolated mRNA can be used in hybridization or
amplification assays that include, but are not limited to, Southern
or Northern analyses, polymerase chain reaction analyses and probe
arrays. One diagnostic method for the detection of mRNA levels
involves contacting the isolated mRNA with a nucleic acid molecule
(probe) that can hybridize to the mRNA encoded by the gene being
detected. The nucleic acid probe can be, for example, a full-length
cDNA, or a portion thereof, such as an oligonucleotide of at least
7, 15, 30, 50, 100, 250 or 500 nucleotides in length and sufficient
to specifically hybridize under stringent conditions to a mRNA or
genomic DNA encoding a biomarker of the present invention. Other
suitable probes for use in the diagnostic assays of the invention
are described herein. Hybridization of an mRNA with the probe
indicates that the biomarker in question is being expressed.
[0177] In one format, the mRNA is immobilized on a solid surface
and contacted with a probe, for example by running the isolated
mRNA on an agarose gel and transferring the mRNA from the gel to a
membrane, such as nitrocellulose. In an alternative format, the
probe(s) are immobilized on a solid surface and the mRNA is
contacted with the probe(s), for example, in an Affymetrix gene
chip array. A skilled artisan can readily adapt known mRNA
detection methods for use in detecting the level of mRNA encoded by
the biomarkers of the present invention.
[0178] An alternative method for determining the level of mRNA
biomarker in a sample involves the process of nucleic acid
amplification, e.g., by RT-PCR (the experimental embodiment set
forth in Mullis, 1987, U.S. Pat. No. 4,683,202), ligase chain
reaction (Barany, 1991, Proc. Natl. Acad. Sci. USA, 88:189-193),
self sustained sequence replication (Guatelli et al., 1990, Proc.
Natl. Acad. Sci. USA 87:1874-1878), transcriptional amplification
system (Kwoh et al., 1989, Proc. Natl. Acad. Sci. USA
86:1173-1177), Q-Beta Replicase (Lizardi et al., 1988,
Bio/Technology 6:1197), rolling circle replication (Lizardi et al.,
U.S. Pat. No. 5,854,033) or any other nucleic acid amplification
method, followed by the detection of the amplified molecules using
techniques well known to those of skill in the art. These detection
schemes are especially useful for the detection of nucleic acid
molecules if such molecules are present in very low numbers. As
used herein, amplification primers are defined as being a pair of
nucleic acid molecules that can anneal to 5' or 3' regions of a
gene (plus and minus strands, respectively, or vice-versa) and
contain a short region in between. In general, amplification
primers are from about 10 to 30 nucleotides in length and flank a
region from about 50 to 200 nucleotides in length. Under
appropriate conditions and with appropriate reagents, such primers
permit the amplification of a nucleic acid molecule comprising the
nucleotide sequence flanked by the primers.
[0179] For in situ methods, mRNA does not need to be isolated from
the tumor cells prior to detection. In such methods, a cell or
tissue sample is prepared and/or processed using known histological
methods. The sample is then immobilized on a support, typically a
glass slide, and then contacted with a probe that can hybridize to
mRNA that encodes the biomarker.
[0180] As an alternative to making determinations based on the
absolute expression level of the biomarker, determinations can be
based on the normalized expression level of the biomarker.
Expression levels are normalized by correcting the absolute
expression level of a biomarker by comparing its expression to the
expression of a gene that is not a biomarker, e.g., a housekeeping
gene that is constitutively expressed. Suitable genes for
normalization include housekeeping genes such as the actin gene, or
epithelial cell-specific genes. This normalization allows the
comparison of the expression level in one sample, e.g., a patient
sample, to another sample, e.g., a non-tumor sample, or between
samples from different sources.
[0181] Alternatively, the expression level can be provided as a
relative expression level. To determine a relative expression level
of a biomarker (e.g., a mesenchymal biomarker), the level of
expression of the biomarker is determined for 10 or more, 20 or
more, 30 or more, 40 or more, or 50 or more samples of normal
versus cancer cell isolates prior to the determination of the
expression level for the sample in question. The mean expression
level of each of the genes assayed in the larger number of samples
is determined and this is used as a baseline expression level for
the biomarker. The expression level of the biomarker determined for
the test sample (absolute level of expression) is then divided by
the mean expression value obtained for that biomarker. This
provides a relative expression level.
[0182] In another embodiment of the present invention, a biomarker
protein is detected. One type of agent for detecting biomarker
protein of the invention is an antibody capable of binding to such
a protein or a fragment thereof such as, for example, a detectably
labeled antibody. Antibodies can be polyclonal or monoclonal. An
intact antibody, or an antigen binding fragment thereof (e.g., Fab,
F(ab')2, Fv, scFv, single binding chain polypeptide) can be used.
The term "labeled," with regard to the probe or antibody, is
intended to encompass direct labeling of the probe or antibody by
coupling (i.e., physically linking) a detectable substance to the
probe or antibody, as well as indirect labeling of the probe or
antibody by reactivity with another reagent that is directly
labeled. Examples of indirect labeling include detection of a
primary antibody using a fluorescently labeled secondary antibody
and end-labeling of a DNA probe with biotin such that it can be
detected with fluorescently labeled streptavidin.
[0183] Proteins from tumor cells can be isolated using techniques
that are well known to those of skill in the art. The protein
isolation methods employed can, for example, be such as those
described in Harlow and Lane (Harlow and Lane, 1988, Antibodies: A
Laboratory Manual, Cold Spring Harbor Laboratory Press, Cold Spring
Harbor, N.Y.).
[0184] A variety of formats can be employed to determine whether a
sample contains a protein that binds to a given antibody. Examples
of such formats include, but are not limited to, enzyme immunoassay
(EIA), radioimmunoassay (RIA), Western blot analysis and enzyme
linked immunoabsorbant assay (ELISA). A skilled artisan can readily
adapt known protein/antibody detection methods for use in
determining whether tumor cells express a biomarker of the present
invention.
[0185] In one format, antibodies, or antibody fragments or
derivatives, can be used in methods such as Western blots or
immunofluorescence techniques to detect the expressed proteins. In
such uses, either the antibody or proteins can be immobilized on a
solid support. Suitable solid phase supports or carriers include
any support capable of binding an antigen or an antibody.
Well-known supports or carriers include glass, polystyrene,
polypropylene, polyethylene, dextran, nylon, amylases, natural and
modified celluloses, polyacrylamides, gabbros, and magnetite. One
skilled in the art will know many other suitable carriers for
binding antibody or antigen, and will be able to adapt' such
support for use with the present invention. For example, protein
isolated from tumor cells can be run on a polyacrylamide gel
electrophoresis and immobilized onto a solid phase support such as
nitrocellulose. The support can then be washed with suitable
buffers followed by treatment with the detectably labeled antibody.
The solid phase support can then be washed with the buffer a second
time to remove unbound antibody. The amount of bound label on the
solid support can then be detected by conventional means.
[0186] For ELISA assays, specific binding pairs can be of the
immune or non-immune type. Immune specific binding pairs are
exemplified by antigen-antibody systems or hapten/anti-hapten
systems. There can be mentioned fluorescein/anti-fluorescein,
dinitrophenyl/anti-dinitrophenyl, biotin/anti-biotin,
peptide/anti-peptide and the like. The antibody member of the
specific binding pair can be produced by customary methods familiar
to those skilled in the art. Such methods involve immunizing an
animal with the antigen member of the specific binding pair. If the
antigen member of the specific binding pair is not immunogenic,
e.g., a hapten, it can be covalently coupled to a carrier protein
to render it immunogenic. Non-immune binding pairs include systems
wherein the two components share a natural affinity for each other
but are not antibodies. Exemplary non-immune pairs are
biotin-streptavidin, intrinsic factor-vitamin B12, folic
acid-folate binding protein and the like.
[0187] A variety of methods are available to covalently label
antibodies with members of specific binding pairs. Methods are
selected based upon the nature of the member of the specific
binding pair, the type of linkage desired, and the tolerance of the
antibody to various conjugation chemistries. Biotin can be
covalently coupled to antibodies by utilizing commercially
available active derivatives. Some of these are
biotin-N-hydroxy-succinimide which binds to amine groups on
proteins; biotin hydrazide which binds to carbohydrate moieties,
aldehydes and carboxyl groups via a carbodiimide coupling; and
biotin maleimide and iodoacetyl biotin which bind to sulfhydryl
groups. Fluorescein can be coupled to protein amine groups using
fluorescein isothiocyanate. Dinitrophenyl groups can be coupled to
protein amine groups using 2,4-dinitrobenzene sulfate or
2,4-dinitrofluorobenzene. Other standard methods of conjugation can
be employed to couple monoclonal antibodies to a member of a
specific binding pair including dialdehyde, carbodiimide coupling,
homofunctional cross-linking, and heterobifunctional cross-linking.
Carbodiimide coupling is an effective method of coupling carboxyl
groups on one substance to amine groups on another. Carbodiimide
coupling is facilitated by using the commercially available reagent
1-ethyl-3-(dimethyl-aminopropyl)-carbodiimide (EDAC).
[0188] Homobifunctional cross-linkers, including the bifunctional
imidoesters and bifunctional N-hydroxysuccinimide esters, are
commercially available and are employed for coupling amine groups
on one substance to amine groups on another. Heterobifunctional
cross-linkers are reagents which possess different functional
groups. The most common commercially available heterobifunctional
cross-linkers have an amine reactive N-hydroxysuccinimide ester as
one functional group, and a sulfhydryl reactive group as the second
functional group. The most common sulfhydryl reactive groups are
maleimides, pyridyl disulfides and active halogens. One of the
functional groups can be a photoactive aryl nitrene, which upon
irradiation reacts with a variety of groups.
[0189] The detectably-labeled antibody or detectably-labeled member
of the specific binding pair is prepared by coupling to a reporter,
which can be a radioactive isotope, enzyme, fluorogenic,
chemiluminescent or electrochemical materials. Two commonly used
radioactive isotopes are 125I and 3H. Standard radioactive isotopic
labeling procedures include the chloramine T, lactoperoxidase and
Bolton-Hunter methods for 125I and reductive methylation for 3H.
The term "detectably-labeled" refers to a molecule labeled in such
a way that it can be readily detected by the intrinsic enzymatic
activity of the label or by the binding to the label of another
component, which can itself be readily detected.
[0190] Enzymes suitable for use in this invention include, but are
not limited to, horseradish peroxidase, alkaline phosphatase,
.beta.-galactosidase, glucose oxidase, luciferases, including
firefly and renilla, .beta.-lactamase, urease, green fluorescent
protein (GFP) and lysozyme. Enzyme labeling is facilitated by using
dialdehyde, carbodiimide coupling, homobifunctional cross-linkers
and heterobifunctional cross-linkers as described above for
coupling an antibody with a member of a specific binding pair.
[0191] The labeling method chosen depends on the functional groups
available on the enzyme and the material to be labeled, and the
tolerance of both to the conjugation conditions. The labeling
method used in the present invention can be one of, but not limited
to, any conventional methods currently employed including those
described by Engvall and Pearlmann, Immunochemistry 8, 871 (1971),
Avrameas and Temynck, Immunochemistry 8, 1175 (1975), Ishikawa et
al., J. Immunoassay 4(3):209-327 (1983) and Jablonski, Anal.
Biochem. 148:199 (1985).
[0192] Labeling can be accomplished by indirect methods such as
using spacers or other members of specific binding pairs. An
example of this is the detection of a biotinylated antibody with
unlabeled streptavidin and biotinylated enzyme, with streptavidin
and biotinylated enzyme being added either sequentially or
simultaneously. Thus, according to the present invention, the
antibody used to detect can be detectably-labeled directly with a
reporter or indirectly with a first member of a specific binding
pair. When the antibody is coupled to a first member of a specific
binding pair, then detection is effected by reacting the
antibody-first member of a specific binding complex with the second
member of the binding pair that is labeled or unlabeled as
mentioned above.
[0193] Moreover, the unlabeled detector antibody can be detected by
reacting the unlabeled antibody with a labeled antibody specific
for the unlabeled antibody. In this instance "detectably-labeled"
as used above is taken to mean containing an epitope by which an
antibody specific for the unlabeled antibody can bind. Such an
anti-antibody can be labeled directly or indirectly using any of
the approaches discussed above. For example, the anti-antibody can
be coupled to biotin which is detected by reacting with the
streptavidin-horseradish peroxidase system discussed above. Thus,
in one embodiment, biotin is utilized. The biotinylated antibody is
in turn reacted with streptavidin-horseradish peroxidase complex.
Orthophenylenediamine, 4-chloro-naphthol, tetramethylbenzidine
(TMB), ABTS, BTS or ASA can be used for chromogenic detection.
[0194] In one immunoassay format for practicing this invention, a
forward sandwich assay is used in which the capture reagent has
been immobilized, using conventional techniques, on the surface of
a support. Suitable supports used in assays include synthetic
polymer supports, such as polypropylene, polystyrene, substituted
polystyrene, e.g., aminated or carboxylated polystyrene,
polyacrylamides, polyamides, polyvinylchloride, glass beads,
agarose, or nitrocellulose.
[0195] IV. Anti-LOX Antibodies and Anti-LOXL2 Antibodies
[0196] Provided herein are antibodies that can be used to diagnose
angiogenesis and associated diseases, fibrosis and associated
diseases, tumors or metastasis. Provided herein are antibodies that
inhibit angiogenesis and associated diseases, inhibit fibrosis and
associated diseases, and treat tumors or metastasis. Provided
herein are antibodies that can be used to monitor efficacy of
treatment regimens and protocols and the like as described
throughout the present application and known in the art. Antibodies
and antigen binding fragments useful in such methods are those, for
example, that specifically bind LOX or LOXL2.
[0197] The disclosure also describes cell lines which produce the
antibodies or functional fragments thereof, methods for producing
the cell lines, and methods for producing the antibodies or
functional fragments thereof.
[0198] The term "antibody" or "antibody molecule" in the various
grammatical forms is used herein as a collective noun that refers
to a population of immunoglobulin molecules and/or immunologically
active portions of immunoglobulin molecules, i.e., molecules that
contain an antibody combining site or paratope. Thus, reference to
an "antibody" also includes reference to any of the antigen binding
fragments of antibodies.
[0199] As used herein, "immunoreactive" refers to antibodies or
fragments thereof that are specific to a sequence of amino acid
residues ("binding site" or "epitope"), yet if are cross-reactive
to other peptides/proteins, are not toxic at the levels at which
they are formulated for administration to human use. "Epitope"
refers to that portion of an antigen capable of forming a binding
interaction with an antibody or antigen binding fragment thereof.
Such binding interaction can be manifested as an intermolecular
contact with one or more amino acid residues of a CDR. Antigen
binding can involve a CDR3 or a CDR3 pair. An epitope can be a
linear peptide sequence (i.e., "continuous") or can be composed of
noncontiguous amino acid sequences (i.e., "conformational" or
"discontinuous"). The term "preferentially binds" means that the
binding agent binds to the binding site with greater affinity than
it binds unrelated amino acid sequences.
[0200] As used herein, the term "affinity" refers to the
equilibrium constant for the reversible binding of two agents and
is expressed as a dissociation constant (Kd). Affinity can be at
least 1-fold greater, at least 2-fold greater, at least 3-fold
greater, at least 4-fold greater, at least 5-fold greater, at least
6-fold greater, at least 7-fold greater, at least 8-fold greater,
at least 9-fold greater, at least 10-fold greater, at least 20-fold
greater, at least 30-fold greater, at least 40-fold greater, at
least 50-fold greater, at least 60-fold greater, at least 70-fold
greater, at least 80-fold greater, at least 90-fold greater, at
least 100-fold greater, or at least 1000-fold greater, or more,
than the affinity of an antibody for unrelated amino acid
sequences. Affinity of an antibody to a target protein can be, for
example, from about 100 nanomolar (nM) to about 0.1 nM, from about
100 nM to about 1 picomolar (pM), or from about 100 nM to about 1
femtomolar (fM) or more. As used herein, the term "avidity" refers
to the resistance of a complex of two or more agents to
dissociation after dilution. The terms "immunoreactive" and
"preferentially binds" are used interchangeably herein with respect
to antibodies and/or antigen-binding fragments.
[0201] The term "antibody" also includes molecules which have been
engineered through the use of molecular biological technique to
include only portions of the native molecule as long as those
molecules have the ability to bind a particular antigen or sequence
of amino acids with the required specificity. Such alternative
antibody molecules include classically known portions of the
antibody molecules, single chain antibodies, and single chain
binding molecules.
[0202] An "antibody combining site" is that structural portion of
an antibody molecule comprised of heavy and light chain variable
and hypervariable regions that specifically binds antigen.
[0203] As used herein, the term "CDR" or "complementarity
determining region" is intended to mean the non-contiguous antigen
combining sites found within the variable region of both heavy and
light chain polypeptides. These particular regions have been
described by Kabat et al., J. Biol. Chem. 252:6609-6616 (1977);
Kabat et al., U.S. Dept. of Health and Human Services, "Sequences
of proteins of immunological interest" (1991); by Chothia et al.,
J. Mol. Biol. 196:901-917 (1987); and MacCallum et al., J. Mol.
Biol. 262:732-745 (1996), where the definitions include overlapping
or subsets of amino acid residues when compared against each other.
Nevertheless, application of either definition to refer to a CDR of
an antibody or grafted antibodies or variants thereof is intended
to be within the scope of the term as defined and used herein. The
amino acid residues which encompass the CDRs as defined by each of
the above cited references are set forth below in Table 1 as a
comparison.

[0204] As used herein, the term "framework" when used in reference
to an antibody variable region is intended to mean all amino acid
residues outside the CDR regions within the variable region of an
antibody. A variable region framework is generally a discontinuous
amino acid sequence between about 100-120 amino acids in length but
is intended to reference only those amino acids outside of the
CDRs. As used herein, the term "framework region" is intended to
mean each domain of the framework that is separated by the
CDRs.
[0205] "An inhibitor of LOX activity" or "an inhibitor of LOXL2
activity" can be an antibody or an antigen binding fragment thereof
that directly or indirectly inhibits activity of lysyl oxidase,
including but not limited to gene expression, post-translation
modification, enzymatic processing or cleavage, binding to a
modulator of LOX/LOXL2, enzymatic activity of LOX/LOXL2 or any
other activity described herein.
[0206] As used herein, the term "antibody" refers to an isolated or
recombinant binding agent that comprises the necessary variable
region sequences to specifically bind an antigenic epitope.
Therefore, an antibody is any form of antibody or fragment thereof
that exhibits the desired biological activity, e.g., binding the
specific target antigen. Thus, it is used in the broadest sense and
specifically covers monoclonal antibodies (including full length
monoclonal antibodies), polyclonal antibodies, human antibodies,
humanized antibodies, chimeric antibodies, diabodies, multispecific
antibodies (e.g., bispecific antibodies), and antibody fragments
including but not limited to single chain binding polypeptides, VH,
VL, Fv, scFv, Fab, and Fab2, etc., so long as they exhibit the
desired biological activity. The term "human antibody" therefore
refers to antibodies containing sequences of human origin, except
for possible non-human CDR regions, and does not imply that the
full structure of an Ig molecule be present, only that the antibody
has minimal immunogenicity in a human.
[0207] The term "binding" refers to a direct association between
two molecules, due to, for example, covalent, electrostatic,
hydrophobic, and ionic and/or hydrogen-bond interactions, including
interactions such as salt bridges and water bridges. The term
"specific binding" is applicable to a situation in which an
antibody or antigen binding fragment thereof does not show any
significant binding to molecules other than its epitope. In one
embodiment, an antibody or antigen binding fragment thereof
specifically binds to a human LOX or to human LOXL2 with a
dissociation constant Kd equal to or lower than about 100 nM, lower
than about 10 nM, lower than about 1 nM, lower than about 0.5 nM,
lower than about 0.1 nM, lower than about 0.01 nM, or lower than
about 0.005 nM measured at a temperature of about 4.degree. C.,
25.degree. C., 37.degree. C. or 42.degree. C.
[0208] Conventional methods can be used to prepare antibodies. For
example, by using a peptide or full length lysyl oxidase protein,
polyclonal antisera or monoclonal antibodies can be made using
standard methods. A mammal, (e.g., a mouse, hamster, or rabbit) can
be immunized with an immunogenic form of the peptide that elicits
an antibody response in the mammal. Techniques for conferring
enhanced immunogenicity on a peptide include conjugation to
carriers or other techniques well known in the art. For example,
the protein or peptide can be administered in the presence of
adjuvant. The progress of immunization can be monitored by
detection of antibody titers in plasma or serum. Standard ELISA or
other immunoassay procedures can be used with the immunogen as
antigen to assess the levels of antibodies. Following immunization,
antisera can be obtained and, if desired, polyclonal antibodies
isolated from the sera.
[0209] The antibodies can be generated in cell culture, in phage,
or in various animals, including but not limited to cows, rabbits,
goats, mice, rats, hamsters, guinea pigs, sheep, dogs, cats,
monkeys, chimpanzees, apes. Therefore, an antibody useful in the
present methods is typically a mammalian antibody. Phage techniques
can be used to isolate an initial antibody or to generate variants
with altered specificity or avidity characteristics. Such
techniques are routine and well known in the art. In one
embodiment, the antibody is produced by recombinant means known in
the art. For example, a recombinant antibody can be produced by
transfecting a host cell with a vector comprising a DNA sequence
encoding the antibody. One or more vectors can be used to transfect
the DNA sequence expressing at least one VL and one VH region in
the host cell. Exemplary descriptions of recombinant means of
antibody generation and production include Delves, Antibody
Production: Essential Techniques (Wiley, 1997); Shephard, et al.,
Monoclonal Antibodies (Oxford University Press, 2000); and Goding,
Monoclonal Antibodies: Principles and Practice (Academic Press,
1993).
[0210] Antibodies also can be made according to the protocol
described by in Kenney, et al. ("Production of monoclonal
antibodies using a secretion capture report web." Biotechnology
13:787-790, 1995). Briefly, mice are injected subcutaneously
(s.c.), with antigen in an adjuvant formulation. For peptide
antigens, peptides are conjugated to bovine serum albumin and
formulated in Freund's Adjuvant (FA) prior to immunization. For
protein antigens, the protein is formulated in Alhydrogel-Muramyl
Dipeptide (ALD/MDP) adjuvant. Cells from the spleen and lymph nodes
of the mice are isolated and fused with appropriate cells and
cultured. A hybridoma library of HAT-selected cells is isolated and
is cloned. Cells are sorted and sera and supernatants are screened
for the presence of antibodies.
[0211] "Antibody fragments" comprise a portion of an intact
antibody, and can include the antigen binding or variable region of
an intact antibody. Examples of antibody fragments include Fab,
Fab', F(ab')2, Fv fragments, scFv fragments, diabodies, linear
antibodies (Zapata et al., Protein Eng. 8(10): 1057-1062 (1995)),
single-chain antibody molecules, single chain binding polypeptides,
and multispecific antibodies formed from antibody fragments. Papain
digestion of antibodies produces two identical antigen-binding
fragments, called "Fab" fragments, each with a single
antigen-binding site, and a residual "Fc" fragment, a designation
reflecting the ability to crystallize readily. Pepsin treatment
yields an F(ab')2 fragment that has two antigen combining sites and
is still capable of cross-linking antigen.
[0212] A "single chain binding polypeptide" refers to a polypeptide
having a heavy chain variable region, a light chain variable region
and, optionally, an immunoglobulin Fc region. Such a molecule is a
single chain variable fragment optionally having effector function
through the presence of the immunoglobulin Fc region. Methods of
preparing single chain binding polypeptides are known in the art
(e.g., US. Patent Application 2005/0238646).
[0213] "Fv" refers to an antibody fragment which contains a
complete antigen-recognition and -binding site. This region
consists of a dimer of one heavy- and one light chain variable
domain in tight, non-covalent association. It is in this
configuration that the three CDRS of each variable domain interact
to define an antigen-binding site on the surface of the VH-VL
dimer. Collectively, the six CDRs confer antigen-binding
specificity to the antibody. However, even a single variable domain
(or half of an Fv comprising only three CDRs specific for an
antigen) has the ability to recognize and bind antigen, although at
a lower affinity than the entire binding site.
[0214] A "Fab" fragment contains a "Fv" and also contains the
constant domain of the light chain and the first constant domain
(CH1) of the heavy chain. Fab fragments differ from Fab' fragments
by the addition of a few residues at the carboxy terminus of the
heavy chain CH1 domain including one or more cysteines from the
antibody hinge region. Fab'-SH is the designation herein for Fab'
in which the cysteine residue(s) of the constant domains bear a
free thiol group. F(ab')2 antibody fragments originally were
produced as pairs of Fab' fragments which have hinge cysteines
between them. Other chemical couplings of antibody fragments are
also known.
[0215] The "light chains" of antibodies (immunoglobulins) from any
vertebrate species can be assigned to one of two clearly distinct
types, called kappa and lambda, based on the amino acid sequences
of their constant domains.
[0216] Depending on the amino acid sequence of the constant domain
of their heavy chains, immunoglobulins can be assigned to different
classes. There are five major classes of immunoglobulins: IgA, IgD,
IgE, IgG, and IgM, and several of these can be further divided into
subclasses (isotypes), e.g., IgG1, IgG2, IgG3, IgG4, IgA1, and
IgA2. The heavy-chain constant domains (Fc) that correspond to the
different classes of immunoglobulins are called .alpha., .delta.,
.epsilon., .gamma., and .mu., respectively. The subunit structures
and three-dimensional configurations of different classes of
immunoglobulins are well known.
[0217] The "light chains" of antibodies (immunoglobulins) from any
vertebrate species can be assigned to one of two clearly distinct
types, called kappa or (".kappa.") and lambda or (".lamda."), based
on the amino acid sequences of their constant domains.
[0218] "Single-chain Fv" or "sFv" antibody fragments comprise the
VH and VL domains of antibody, wherein these domains are present in
a single polypeptide chain. A Fv polypeptide can further include,
if needed, a polypeptide linker between the VH and VL domains,
which enables the sFv to form a desired structure for antigen
binding. For a review of sFv, see Pluckthun in The Pharmacology of
Monoclonal Antibodies, vol. 113, Rosenburg and Moore eds.,
Springer-Verlag, New York, pp. 269-315 (1994).
[0219] The term "diabodies" refers to small antibody fragments with
two antigen-binding sites, which fragments contain a heavy-chain
variable domain (VH) connected to a light-chain variable domain
(VL) in the same polypeptide chain (VH-VL). By using a linker that
is too short to allow pairing between the two domains on the same
chain, the domains are forced to pair with the complementary
domains of another chain and create two antigen-binding sites.
Diabodies are described more fully in, for example, EP 404,097; WO
93/11161; and Hollinger et al., Proc. Natl. Acad. Sci. USA,
90:6444-6448 (1993).
[0220] An antibody can also be a bispecific antibody. Bispecific
antibodies are monoclonal, chimeric, human or humanized antibodies
that have binding specificities for at least two different
antigens. In the present case, one of the binding specificities is,
for example, LOX or LOXL2, the other one is for any other antigen,
such as, for example, a cell-surface protein or receptor or
receptor subunit. In additional embodiments, a bispecific antibody
is specific for LOX and LOXL2.
[0221] Methods for making bispecific antibodies are known in the
art. Traditionally, the recombinant production of bispecific
antibodies is based on the co-expression of two immununoglobulin
heavy-chain/light-chain pairs, where the two heavy chains have
different specificities (Milstein and Cuello, Nature, 305:537 539
(1983)). Because of the random assortment of immunoglobulin heavy
and light chains, these hybridomas (quadromas) produce a potential
mixture of ten different antibody molecules, of which only one has
the correct bispecific structure. The purification of the correct
molecule is usually accomplished by affinity chromatography steps.
Similar procedures are disclosed in WO 93/08829, published 13 May
1993, and in Traunecker et al., EMBO J., 10:3655-3659 (1991).
[0222] Antibody variable domains with the desired binding
specificities (antibody-antigen combining sites) can be fused to
immunoglobulin constant domain sequences using conventional methods
known in the art. The fusion is, generally, with an immunoglobulin
heavy-chain constant domain, containing at least part of the hinge,
CH2, and CH3 regions. In one embodiment, the first heavy-chain
constant region (CH1) containing the site necessary for light-chain
binding is present in at least one of the fusions. DNAs encoding
the immunoglobulin heavy-chain fusions and, if desired, the
immunoglobulin light chain, can be inserted into separate
expression vectors, and can be co-transfected into a suitable host
organism. For further details of generating bispecific antibodies
see, for example, Suresh et al., Methods in Enzymology, 121:210
(1986).
[0223] According to another approach described in WO 96/27011, the
interface between a pair of antibody molecules can be engineered to
maximize the percentage of heterodimers that are recovered from
recombinant cell culture. The interface can comprise at least a
part of the CH3 region of an antibody constant domain. In this
method, one or more small amino acid side chains from the interface
of the first antibody molecule are replaced with larger side chains
(e.g., tyrosine or tryptophan). Compensatory "cavities" of
identical or similar size to the large side chain(s) are created on
the interface of the second antibody molecule by replacing large
amino acid side chains with smaller ones (e.g., alanine or
threonine). This provides a mechanism for increasing the yield of
the heterodimer over other unwanted end-products such as
homodimers.
[0224] Bispecific antibodies can be prepared as full length
antibodies or antibody fragments (e.g., F(ab')2 bispecific
antibodies). Techniques for generating bispecific antibodies from
antibody fragments have been described in the literature. For
example, bispecific antibodies can be prepared can be prepared
using chemical linkage. Brennan et al., Science 229:81 (1985)
describe a procedure wherein intact antibodies are proteolytically
cleaved to generate F(ab')2 fragments. These fragments are reduced
in the presence of the dithiol complexing agent sodium arsenite to
stabilize vicinal dithiols and prevent intermolecular disulfide
formation. The Fab' fragments generated are then converted to
thionitrobenzoate (TNB) derivatives. One of the Fab'-TNB
derivatives is then reconverted to the Fab'-thiol by reduction with
mercaptoethylamine and is mixed with an equimolar amount of the
other Fab'-TNB derivative to form the bispecific antibody. The
bispecific antibodies produced can be used as agents for the
selective immobilization of enzymes.
[0225] Fab' fragments may be directly recovered from E. coli and
chemically coupled to form bispecific antibodies. Shalaby et al.,
J. Exp. Med. 175:217-225 (1992) describe the production of a fully
humanized bispecific antibody F(ab')2 molecule. Each Fab' fragment
was separately secreted from E. coli and subjected to directed
chemical coupling in vitro to form the bispecific antibody. The
bispecific antibody thus formed was able to bind to cells
over-expressing the ErbB2 receptor and normal human T cells, as
well as trigger the lytic activity of human cytotoxic lymphocytes
against human breast tumor targets.
[0226] Various techniques for making and isolating bispecific
antibody fragments directly from recombinant cell culture have also
been described. For example, bispecific antibodies have been
produced using leucine zippers. Kostelny et al., J. Immunol.
148(5):1547-1553 (1992). The leucine zipper peptides from the Fos
and Jun proteins were linked to the Fab' portions of two different
antibodies by gene fusion. The antibody homodimers were reduced at
the hinge region to form monomers and then re-oxidized to form the
antibody heterodimers. This method can also be utilized for the
production of antibody homodimers. The "diabody" technology
described by Hollinger et al., Proc. Natl. Acad. Sci. USA
90:6444-6448 (1993) has provided an alternative mechanism for
making bispecific antibody fragments. The fragments comprise a
heavy-chain variable domain (VH) connected to a light-chain
variable domain (VL) by a linker that is too short to allow pairing
between the two domains on the same chain. Accordingly, the VH and
VL domains of one fragment are forced to pair with the
complementary VL and VH domains of another fragment, thereby
forming two antigen-binding sites. Another strategy for making
bispecific antibody fragments by the use of single-chain Fv (sFv)
dimers has also been reported. See, Gruber et al., J. Immunol.
152:5368 (1994).
[0227] Antibodies with more than two valencies are contemplated.
For example, trispecific antibodies can be prepared. Tutt et al.,
J. Immunol. 147:60 (1991).
[0228] Exemplary bispecific antibodies may bind to two different
epitopes on a given LOX or LOXL2 polypeptide herein. Alternatively,
an anti-LOX or anti-LOXL2 polypeptide arm may be combined with an
arm which binds to a triggering molecule on a leukocyte such as a
T-cell receptor molecule (e.g., CD2, CD3, CD28, or B7), or Fc
receptors for IgG (Fc.gamma.R), such as Fc.gamma.RI (CD64),
Fc.gamma.RII (CD32) and Fc.gamma.RIII (CD16) so as to focus
cellular defense mechanisms to the cell expressing a particular
target polypeptide. Bispecific antibodies can also be used to
localize cytotoxic agents to cells that express a particular target
polypeptide. These antibodies possess a target binding arm and an
arm that binds a cytotoxic agent or a radionuclide chelator, such
as EOTUBE, DPTA, DOTA, or TETA. Another bispecific antibody of
interest binds the target polypeptide and further binds tissue
factor (TF).
[0229] The anti-LOX antibody or anti-LOXL2 antibody can also be a
heteroconjugate antibody. Heteroconjugate antibodies are composed
of two covalently joined antibodies. Such antibodies have, for
example, been proposed to target immune system cells to unwanted
cells (U.S. Pat. No. 4,676,980) and for treatment of HIV infection
(WO 91/00360 and WO 92/200373). Antibodies can be prepared in vitro
using known methods in synthetic protein chemistry, including those
involving cross-linking agents. For example, immunotoxins can be
constructed using a disulfide exchange reaction or by forming a
thioether bond. Examples of suitable reagents for this purpose
include, but are not limited to, iminothiolate and
methyl-4-mercaptobutyrimidate and those disclosed, for example, in
U.S. Pat. No. 4,676,980.
[0230] It may be desirable to modify an anti-LOX antibody or
anti-LOXL2 antibody with respect to effector function, so as to
enhance, e.g., the effectiveness of the antibody in treating or
preventing cancer metastasis. For example, cysteine residue(s) may
be introduced into the Fc region, thereby allowing interchain
disulfide bond formation in this region. The homodimeric antibody
thus generated can have improved internalization capability and/or
increased complement-mediated cell killing and antibody-dependent
cellular cytotoxicity (ADCC). See Caron et al., J. Exp Med., 176:
1191-1195 (1992) and Shopes, J. Immunol., 148: 2918-2922 (1992).
Homodimeric antibodies with enhanced anti-tumor activity can also
be prepared using heterobifunctional cross-linkers as described in
Wolff et al. Cancer Research, 53: 2560-2565'(1993). Alternatively,
an antibody can be engineered that has dual Fc regions and may
thereby have enhanced complement lysis and ADCC capabilities. See
Stevenson et al., Anti-Cancer Drug Design, 3: 219-230 (1989).
[0231] An "isolated antibody" is one that has been identified and
separated and/or recovered from a component of its natural
environment. Contaminant components of its natural environment are
materials that would interfere with diagnostic or therapeutic uses
for the antibody, and can include, for example, enzymes, hormones,
and other proteinaceous or non-proteinaceous solutes. In one
embodiment, an antibody will be purified (1) to greater than 80%,
85%, 90%, 95%, or 99% by weight of antibody as determined by the
Lowry method, (2) to a degree sufficient to obtain at least 15
residues of N-terminal or internal amino acid sequence by use of a
spinning cup sequenator, and/or (3) to homogeneity by SDS-PAGE
under reducing or non-reducing conditions using Coomassie blue or
silver stain. The term "isolated antibody" includes within its
scope an antibody in situ within recombinant cells since at least
one component of the antibody's natural environment will not be
present. Generally, isolation of an antibody or antigen binding
fragment thereof will include at least one purification step.
[0232] An antibody can be a humanized antibody or a human antibody.
Humanized forms of non-human (e.g., murine) antibodies include, for
example, chimeric immunoglobulins, immunoglobulin chains or
fragments thereof (such as Fv, scFv, Fab, Fab', F(ab')2, single
chain binding polypeptide, VH, VL, or other antigen-binding
subsequences of antibodies) which contain minimal sequence derived
from non-human immunoglobulin. Chimeric antibodies include those in
which the heavy and light chain variable regions are combined with
human constant regions (Fe). Humanized antibodies include human
immunoglobulins (recipient antibody) in which residues from a
complementary determining region (CDR) of the recipient are
replaced by residues from a CDR of a non-human species (donor
antibody) such as mouse, rat or rabbit having the desired
specificity, affinity and capacity. In some instances, Fv framework
residues of the human immunoglobulin are replaced by corresponding
non-human residues. Humanized antibodies may also comprise residues
that are found neither in the recipient antibody nor in the
imported CDR or framework sequences. In general, the humanized
antibody will comprise substantially all of at least one, and
typically two, variable domains, in which all or substantially all
of the CDR regions correspond to those of a non-human
immunoglobulin and all or substantially all of,the FR regions are
those of a human immunoglobulin consensus sequence.
[0233] A humanized antibody can also contain at least a portion of
an immunoglobulin constant region (Fc), typically that of a human
immunoglobulin (Jones et al., Nature, 321:522-525 (1986); Riechmann
et al., Nature, 332:323-329(1988); and Presta, Curr. Op. Struct.
Biol. 2:593-596 (1992)).
[0234] Methods for humanizing non-human antibodies are well known
in the art. Generally, a humanized antibody has one or more amino
acid residues introduced into it from a source that is non-human.
These non-human amino acid residues are often referred to as
"import" or "donor" residues, which are typically taken from an
"import" or "donor" variable domain. Humanization can be
essentially performed following the method of Winter and co-workers
(Jones et al., Nature, 321:522 525 (1986); Riechmann et al.,
Nature, 332:323 327 (1988)); Verhoeyen et al. Science, 239:1534
1536 (1988)), by substituting rodent CDRs or CDR sequences for the
corresponding sequences of a human antibody. Accordingly, such
"humanized" antibodies include chimeric antibodies (U.S. Pat. No.
4,816,567), wherein substantially less than an intact human
variable domain has been substituted by the corresponding sequence
from a non-human species. In practice, humanized antibodies are
typically human antibodies in which some CDR residues and possibly
some FR residues are substituted by residues from analogous sites
in rodent antibodies.
[0235] Human antibodies can also be produced using various
techniques known in the art, including phage display libraries
(Hoogenboom and Winter, J. Mol. Biol., 227:381 (1991); Marks et
al., J. Mol. Biol., 222:581 (1991)). The techniques of Cole et al.
and Boerner et al. are also available for the preparation of human
monoclonal antibodies (Cole et al., Monoclonal Antibodies and
Cancer Therapy, Alan R. Liss, p. 77 (1985) and Boerner et al., J.
Immunol., 147(1):86-95 (1991)). Similarly, human antibodies can be
made by introducing human immunoglobulin loci into transgenic
animals, e.g., mice in which the endogenous immunoglobulin genes
have been partially or completely inactivated. Upon challenge,
human antibody production is observed, which closely resembles that
seen in humans in all respects, including gene rearrangement,
assembly, and antibody repertoire. This approach is described, for
example, in U.S. Pat. Nos. 5,545,807; 5,545,806; 5,569,825;
5,625,126; 5,633,425; 5,661,016, and in the following scientific

[0236] Murine monoclonal antibodies have been developed that bind
LOX or LOXL2 and block the enzymatic activity thereof. Humanized
antibodies and antigen-binding fragments thereof described herein
are created by humanization of the VL and VH sequences of the
murine monoclonal anti-LOX and anti-LOXL2 antibodies.
[0237] Humanized immunoglobulins, including humanized antibodies,
have been constructed by means of genetic engineering. Most
humanized immunoglobulins that have been previously described have
comprised a framework that is identical to the framework of a
particular human immunoglobulin chain (i.e., an acceptor or
recipient), and three CDRs from a non-human (donor) immunoglobulin
chain. As described herein, humanization can also include criteria
by which a limited number of amino acids in the framework of a
humanized immunoglobulin chain are identified and chosen to be the
same as the amino acids at those positions in the donor rather than
in the acceptor, in order to increase the affinity of an antibody
comprising the humanized immunoglobulin chain.
[0238] The present invention is based in part on the model that two
contributing causes of the loss of affinity in prior means of
producing humanized antibodies (using as examples mouse antibodies
as the source of CDRs) are: (1) when the mouse CDRs are combined
with a human framework, the amino acids in the frameworks close to
the CDRs become human instead of mouse. Without intending to be
bound by theory, these changed amino acids may slightly distort the
CDRs (e.g., they may create different electrostatic or hydrophobic
forces than in the donor mouse antibody, and the distorted-CDRs may
not make as effective contacts with the antigen as the CDRs did in
the donor antibody); (2) also, amino acids in the original mouse
antibody that are close to, but not part of, the CDRs (i.e., still
part of the framework), may make contacts with the antigen that
contribute to affinity. These amino acids are lost when the
antibody is humanized because, generally, all framework amino acids
are made human. To circumvent these issues, and to produce
humanized antibodies that have a very strong affinity for a desired
antigen, humanized antibodies and antigen-binging fragments thereof
can be constructed using one or more of the following
principles.
[0239] One principle is that as acceptor, a framework is used from
a particular human immunoglobulin that is unusually homologous to
the donor immunoglobulin to be humanized, or use a consensus
framework from many human antibodies is used as an acceptor. For
example, comparison of the sequence of a mouse heavy (or light)
chain variable region against human heavy (or light) variable
regions in a data bank (for example, the National Biomedical
Research Foundation Protein Identification Resource or the protein
sequence database of the National Center for Biotechnology
Information--NCBI) shows that the extent of homology to different
human regions can vary greatly, for example from about 40% to about
60%, about 70%, about 80%, or higher. By choosing as the acceptor
immunoglobulin one of the human heavy chain variable regions that
is most homologous to the heavy chain variable region of the donor
immunoglobulin, fewer amino acids will be changed in going from the
donor immunoglobulin to the humanized immunoglobulin. By choosing
as the acceptor immunoglobulin one of the human light chain
variable regions that is most homologous to the light chain
variable region of the donor immunoglobulin, fewer amino acids will
be changed in going from the donor immunoglobulin to the humanized
immunoglobulin. Generally, using such techniques, there is a
reduced chance of changing an amino acid near one or more of the
CDRs that distorts their conformation. Moreover, the precise
overall shape of a humanized antibody comprising the humanized
immunoglobulin chain may more closely resemble the shape of the
donor antibody, thereby also reducing the chance of distorting the
CDRS.
[0240] One can also use light and heavy chains from the same human
antibody as acceptor sequences, to improve the likelihood that the
humanized light and heavy chains will make favorable contacts with
each other. Alternatively, one can also use light and heavy chains
from different human antibody germline sequences as acceptor
sequences; when such combinations are used, one can readily
determine whether the VH and VL bind an epitope of interest using
conventional assays (e.g., an ELISA). In one example, the human
antibody will be chosen in which the light and heavy chain variable
regions sequences, taken together, are overall most homologous to
the donor light and heavy chain variable region sequences.
Sometimes greater weight will be given to the heavy chain sequence.
Regardless of how the acceptor immunoglobulin is chosen, higher
affinity can, in some cases, be achieved by selecting a small
number of amino acids in the framework of the humanized
immunoglobulin chain to be the same as the amino acids at those
positions in the donor rather than in the acceptor. Methods of
affinity maturation are known in the art.
[0241] Humanized antibodies generally have at least three potential
advantages over mouse or chimeric antibodies for use in human
therapy. Because the effector portion of an antibody is human, it
is believed to interact better with the other parts of the human
immune system (e.g., destroy the target cells more efficiently by
complement-dependent cytotoxicity (CDC) or antibody-dependent
cellular cytotoxicity (ADCC)). Additionally, the human immune
system should not recognize the framework or constant region of the
humanized antibody as foreign, and therefore the antibody response
against such an injected antibody should be less than against a
totally foreign mouse antibody or a partially foreign chimeric
antibody. Finally, mouse antibodies are known to have a half-life
in the human circulation that is much shorter than the half-life of
human antibodies. Humanized antibodies can, presumably, have a
half-life more similar to naturally-occurring human antibodies,
allowing smaller and less frequent doses to be given.
[0242] Humanization of antibodies and antigen-binding fragments
thereof, can be accomplished via a variety of methods known in the
art and described herein. Similarly, production of humanized
antibodies can also be accomplished via methods known in the art
and described herein.
[0243] Methods for modifications of framework regions are known in
the art and are contemplated herein. Selection of one or more
relevant framework amino acid positions to be altered depends on a
variety of criteria. One criterion for selecting relevant framework
amino acids to change can be the relative differences in amino acid
framework residues between the donor and acceptor molecules.
Selection of relevant framework positions to alter using this
approach has the advantage of avoiding any subjective bias in
residue determination or any bias in CDR binding affinity
contribution by the residue.
[0244] Another criterion that can be used for determining the
relevant amino acid positions to change can be, for example,
selection of framework residues that are known to be important or
to contribute to CDR conformation. For example, canonical framework
residues are important for CDR conformation and/or structure.
Targeting of a canonical framework residue as a relevant position
to change can be used to identify a more compatible amino acid
residue in context with its associated donor CDR sequence.
[0245] The frequency of an amino acid residue at a particular
framework position is another criterion which can be used for
selecting relevant framework amino acid positions to change. For
example, comparison of the selected framework with other framework
sequences within its subfamily can reveal residues that occur at
minor frequencies at a particular position or positions. Positions
harboring less abundant residues are similarly applicable for
selection as a position to alter in the acceptor variable region
framework.
[0246] The relevant amino acid positions to change also can be
selected, for example, based on proximity to a CDR. In certain
contexts, FR residues can participate in CDR conformation and/or
antigen binding. Moreover, this criterion can similarly be used to
prioritize relevant positions selected by other criteria described
herein. Therefore, differentiating between residues proximal and
distal to one or more CDRs represents one way to reduce the number
of relevant positions to change.
[0247] Other criteria for selecting relevant amino acid framework
positions to alter include, for example, residues that are known or
predicted to reside in a three dimensional space near the
antigen-CDR interface or predicted to modulate CDR activity.
Similarly, framework residues that are known to, or predicted to,
form contacts between the heavy (V.sub.H) and light (V.sub.L) chain
variable region interface can be selected. Such framework positions
can affect the conformation and/or affinity of a CDR by modulating
the CDR binding pocket, antigen (epitope) interaction or the
V.sub.H and V.sub.L interaction. Therefore, selection of these
amino acid positions for constructing a diverse population for
screening of binding activity can be used to identify framework
changes which replace residues having detrimental effects on CDR
conformation or compensate for detrimental effects of residues
occurring elsewhere in the framework.
[0248] Other framework residues that can be selected for alteration
include amino acid positions that are inaccessible to solvent. Such
residues are generally buried in the variable region and are,
therefore, capable of influencing the conformation of the CDR or
V.sub.H and V.sub.L interactions. Solvent accessibility can be
predicted, for example, from the relative hydrophobicity of the
environment created by the amino acid side chains of the
polypeptide and/or by known three-dimensional structural data.
[0249] Following selection of relevant amino acid positions in the
donor CDRs, as well as any relevant amino acid positions in the
framework regions desired to be varied, amino acid changes at some
or all of the selected positions can be incorporated into encoding
nucleic acids for the acceptor variable region framework and donor
CDRs. Altered framework or CDR sequences can be individually made
and tested, or can be sequentially or simultaneously combined and
tested.
[0250] The variability at any or all of the altered positions can
range from a few to a plurality of different amino acid residues,
including all twenty naturally occurring amino acids or functional
equivalents and analogues thereof. In some cases, non-naturally
occurring amino acids may also be considered and are known in the
art.
[0251] Selection of the number and location of the amino acid
positions to vary is flexible and can depend on the intended use
and desired efficiency for identification of the altered variable
region having a desirable activity such as substantially the same
or greater binding affinity compared to the donor variable region.
In this regard, the greater the number of changes that are
incorporated into an altered variable region population, the more
efficient it is to identify at least one species that exhibits a
desirable activity, for example, substantially the same or greater
binding affinity as the donor. Alternatively, where the user has
empirical or actual data to the affect that certain amino acid
residues or positions contribute disproportionally to binding
affinity, then it can be desirable to produce a limited population
of altered variable regions which focuses on changes within or
around those identified residues or positions.
[0252] For example, if CDR grafted variable regions are desired, a
large, diverse population of altered variable regions can include
all the non-identical framework region positions between the donor
and acceptor framework and all single CDR amino acid position
changes. Alternatively, a population of intermediate diversity can
include subsets, for example, of only the proximal non-identical
framework positions to be incorporated together with all single CDR
amino acid position changes to, for example, increase affinity of
the humanized antibodies or antigen binding fragments. The
diversity of the above populations can be further increased by, for
example, additionally including all pair-wise CDR amino acid
position changes. In contrast, populations focusing on
predetermined residues or positions which incorporate variant
residues at as few as one framework and/or one CDR amino acid
position can similarly be constructed for screening and
identification of an altered antibody variable region. As with the
above populations, the diversity of such focused populations can be
further increased by additionally expanding the positions selected
for change to include other relevant positions in either or both of
the framework and CDR regions. There are numerous other
combinations ranging from few changes to many changes in either or
both of the framework regions and CDRs that can additionally be
employed, all of which will result in a population of altered
variable regions that can be screened for the identification of at
least one CDR grafted altered variable region having desired
activity, for example, binding activity to LOX/LOXL2. Those skilled
in the art will know, or can determine, which selected residue
positions in the framework or donor CDRs, or subsets thereof, can
be varied to produce a population for screening and identification
of an altered antibody of the invention given the teachings and
guidance provided herein. Codons encoding amino acids are known in
the art.
[0253] Humanized antibodies and antigen-binding fragments can be
made using conventional techniques known in the art. In addition,
recombinantly prepared antibodies can often be produced in large
quantities, particularly when utilizing high level expression
vectors.
[0254] Antibodies can be sequenced using conventional techniques
known in the art and the amino acid sequences of the
complementarity determining regions (CDRs) determined. In one
aspect, the amino acid sequences of one or more of the CDRs is
inserted into a synthetic sequence of, for example, a human
antibody (or antigen-binding fragment thereof) framework to create
a human antibody that could limit adverse side reactions of
treating a human patient with a non-human antibody. The amino acid
sequences of one or more of the CDRs can also be inserted into a
synthetic sequence of, for example, into a binding protein such as
an Avimer.TM. to create a construct for administration to a human
patient. Such techniques can be modified depending on the species
of animal to be treated. For example, for veterinary uses, an
antibody, antigen-binding fragment or binding protein can be
synthesized for administration of a primate, a cow, a horse,
etc.
[0255] In another aspect, using art-recognized techniques such as
those provided and incorporated herein, nucleotides encoding amino
acid sequences of one or more of the CDRs can inserted, for
example, by recombinant techniques in restriction endonuclease
sites of an existing polynucleotide that encodes an antibody,
antigen-binding fragment or binding protein.
[0256] For high level production, the most widely used mammalian
expression system is one which utilizes the gene amplification
procedure offered by dihydrofolate reductase deficient ("dhfr-")
Chinese hamster ovary cells. The system is well known to the
skilled artisan. The system is based upon the dihydrofolate
reductase "dhfr" gene, which encodes the DHFR enzyme, which
catalyzes conversion of dihydrofolate to tetrahydrofolate. In order
to achieve high production, dhfr-CHO cells are transfected with an
expression vector containing a functional dhfr gene, together with
a gene that encodes a desired protein. In this case, the desired
protein is recombinant antibody heavy chain and/or light chain.
[0257] By increasing the amount of the competitive DHFR inhibitor
methotrexate (MTX), the recombinant cells develop resistance by
amplifying the dhfr gene. In standard cases, the amplification unit
employed is much larger than the size of the dhfr gene, and as a
result the antibody heavy chain is co-amplified.
[0258] When large scale production of the protein, such as the
antibody chain, is desired, both the expression level and the
stability of the cells being employed are taken into account. In
long term culture, recombinant CHO cell populations lose
homogeneity with respect to their specific antibody productivity
during amplification, even though they derive from a single,
parental clone.
[0259] The present application provides an isolated polynucleotide
(nucleic acid) encoding an antibody or antigen-binding fragment as
described herein, vectors containing such polynucleotides, and host
cells and expression systems for transcribing and translating such
polynucleotides into polypeptides.
[0260] The present application also provides constructs in the form
of plasmids, vectors, transcription or expression cassettes which
comprise at least one polynucleotide as above.
[0261] The present application also provides a recombinant host
cell which comprises one or more constructs as above. A nucleic
acid encoding any antibody or antigen-binding fragments thereof
described herein as provided itself forms an aspect of the present
application, as does a method of production of the antibody or
antigen-binding fragments thereof described herein which method
comprises expression from encoding nucleic acid therefrom.
Expression can conveniently be achieved by culturing under
appropriate conditions recombinant host cells containing the
nucleic acid. Following production by expression, an antibody or
antigen-binding fragment can be isolated and/or purified using any
suitable technique, then used as appropriate.
[0262] Specific antibodies, antigen-binding fragments, and encoding
nucleic acid molecules and vectors described herein can be provided
isolated and/or purified, e.g., from their natural environment, in
substantially pure or homogeneous form, or, in the case of nucleic
acid, free or substantially free of nucleic acid or genes origin
other than the sequence encoding a polypeptide with the required
function. Nucleic acid can comprise DNA or RNA and can be wholly or
partially synthetic.
[0263] Systems for cloning and expression of a polypeptide in a
variety of different host cells are well known. Suitable host cells
include bacteria, mammalian cells, yeast and baculovirus systems.
Mammalian cell lines available in the art for expression of a
heterologous polypeptide include Chinese hamster ovary cells, HeLa
cells, baby hamster kidney cells, NSO mouse melanoma cells and many
others. A common bacterial host is E. coli.
[0264] The expression of antibodies and antibody fragments in
prokaryotic cells such as E. coli is well established in the art.
For a review, see for example Pluckthun, A. Bio/Technology 9:
545-551 (1991). Expression in eukaryotic cells in culture is also
available to those skilled in the art as an option for production
of the antibodies and antigen-binding fragments described herein,
see for recent reviews, for example Raff, M. E. (1993) Curr.
Opinion Biotech. 4: 573-576; Trill J. J. et al. (1995) Curr.
Opinion Biotech 6: 553-560, each of which is which is incorporated
herein by reference in its entirety.
[0265] Suitable vectors can be chosen or constructed, containing
appropriate regulatory sequences, including promoter sequences,
terminator sequences, polyadenylation sequences, enhancer
sequences, marker genes and other sequences as appropriate. Vectors
can be plasmids, viral e.g. `phage, or phagemid, as appropriate.
For further details see, for example, Molecular Cloning: a
Laboratory Manual: 2nd edition, Sambrook et al., 1989, Cold Spring
Harbor Laboratory Press. Many known techniques and protocols for
manipulation of nucleic acid, for example in preparation of nucleic
acid constructs, mutagenesis, sequencing, introduction of DNA into
cells and gene expression, and analysis of proteins, are described
in detail in Short Protocols in Molecular Biology, Second Edition,
Ausubel et al. eds., John Wiley & Sons, 1992. The disclosures
of Sambrook et al. and Ausubel et al. are incorporated herein by
reference in their entirety.
[0266] Thus, a further aspect provides a host cell containing
nucleic acid as disclosed herein. A still further aspect provides a
method comprising introducing such nucleic acid into a host cell.
The introduction can employ any available technique. For eukaryotic
cells, suitable techniques can include, for example, calcium
phosphate transfection, DEAE Dextran, electroporation, biolistics,
liposome-mediated transfection and transduction using retrovirus or
other virus, e.g., vaccinia or, for insect cells, baculovirus. For
bacterial cells, suitable techniques can include, for example,
calcium chloride transformation, electroporation and transfection
using bacteriophage.
[0267] The introduction can be followed by causing or allowing
expression from the nucleic acid, e.g. by culturing host cells
under conditions for expression of the gene.
[0268] In one embodiment, the nucleic acid is integrated into the
genome (e.g. chromosome) of the host cell. Integration can be
promoted by inclusion of sequences which promote recombination with
the genome, in accordance with standard techniques.
[0269] The present application also provides a method which
comprises using a construct as stated above in an expression system
in order to express the antibodies or antigen-binding fragments
thereof as above.
[0270] The present application also relates to isolated nucleic
acids, such as recombinant DNA molecules or cloned genes, or
degenerate variants thereof, mutants, analogs, or fragments
thereof, which encode an antibody or antigen-binding sequence that
binds LOX or LOXL2 described herein.
[0271] In one aspect, the present application provides a nucleic
acid which codes for an antibody or antigen-binding fragment
thereof which binds LOX or LOXL2 as described herein.
[0272] In a further embodiment, the full DNA sequence of the
recombinant DNA molecule or cloned gene of an antibody or
antigen-binding fragment described herein can be operatively linked
to an expression control sequence which can be introduced into an
appropriate host. The application accordingly extends to
unicellular hosts transformed with the cloned gene or recombinant
DNA molecule comprising a DNA sequence encoding the V.sub.H and/or
V.sub.L, or portions thereof, of the antibody.
[0273] Another feature is the expression of the DNA sequences
disclosed herein. As is well known in the art, DNA sequences can be
expressed by operatively linking them to an expression control
sequence in an appropriate expression vector and employing that
expression vector to transform an appropriate unicellular host.
[0274] Such operative linking of a DNA sequence to an expression
control sequence, of course, includes, if not already part of the
DNA sequence, the provision of an initiation codon, ATG, in the
correct reading frame upstream of the DNA sequence.
[0275] Polynucleotides and vectors can be provided in an isolated
and/or a purified form (e.g., free or substantially free of
polynucleotides of origin other than the polynucleotide encoding a
polypeptide with the required function). As used herein,
"substantially pure" and "substantially free," refer to a solution
or suspension containing less than, for example, 20% or less
extraneous material, 10% or less extraneous material, 5% or less
extraneous material, 4% or less extraneous material, 3% or less
extraneous material, 2% or less extraneous material, or 1% or less
extraneous material.
[0276] A wide variety of host/expression vector combinations can be
employed in expressing the DNA sequences of this invention. Useful
expression vectors, for example, can consist of segments of
chromosomal, non-chromosomal and synthetic DNA sequences. Suitable
vectors include derivatives of SV40 and known bacterial plasmids,
e.g., E. coli plasmids col El, Per1, Pbr322, Pmb9 and their
derivatives, plasmids such as RP4; phage DNAs, e.g., the numerous
derivatives of phage .lamda., e.g., NM989, and other phage DNA,
e.g., M13 and filamentous single stranded phage DNA; yeast plasmids
such as the 2u plasmid or derivatives thereof; vectors useful in
eukaryotic cells, such as vectors useful in insect or mammalian
cells; vectors derived from combinations of plasmids and phage
DNAs, such as plasmids that have been modified to employ phage DNA
or other expression control sequences; and the like.
[0277] Also provided herein is a recombinant host cell which
comprises one or more polynucleotide constructs. A polynucleotide
encoding an antibody or antigen-binding fragment as provided herein
forms an aspect of the present application, as does a method of
production of the antibody or antigen-binding fragment which method
comprises expression from the polynucleotide. Expression can be
achieved, for example, by culturing under appropriate conditions
recombinant host cells containing the polynucleotide. An antibody
or antigen-binding fragment can then be isolated and/or purified
using any suitable technique, and used as appropriate.
[0278] Any of a wide variety of expression control
sequences--sequences that control the expression of a DNA sequence
operatively linked to it--can be used in these vectors to express
the DNA sequences. Such useful expression control sequences
include, for example, the early or late promoters of SV40, CMV,
vaccinia, polyoma or adenovirus, the lac system, the trp system,
the TAC system, the TRC system, the LTR system, the major operator
and promoter regions of phage .lamda., the control regions of fd
coat protein, the promoter for 3-phosphoglycerate kinase or other
glycolytic enzymes, the promoters of acid phosphatase (e.g., Pho5),
the promoters of the yeast -mating factors, and other sequences
known to control the expression of genes of prokaryotic or
eukaryotic cells or their viruses, and various combinations
thereof.
[0279] Systems for cloning and expression of a polypeptide in a
variety of different host cells are well known. Suitable host cells
include bacteria, mammalian cells, yeast and baculovirus systems.
Mammalian cell lines available in the art for expression of a
heterologous polypeptide include Chinese hamster ovary (CHO) cells,
HeLa cells, baby hamster kidney cells, NSO mouse melanoma cells and
many others. A common, bacterial host can be, for example, E.
coli.
[0280] The expression of antibodies or antigen-binding fragments in
prokaryotic cells, such as E. coli, is well established in the art.
For a review, see for example Pluckthun, A. Bio/Technology 9:
545-551 (1991). Expression in eukaryotic cells in culture is also
available to those skilled in the art (Raff, M. E. (1993) Curr.
Opinion Biotech. 4: 573-576; Trill J. J. et al. (1995) Curr.
Opinion Biotech 6: 553-560).
[0281] A wide variety of unicellular host cells are also useful in
expressing the DNA sequences. These hosts include well-known
eukaryotic and prokaryotic hosts, such as strains of E. coli,
Pseudomonas, Bacillus, Streptomyces, fungi such as yeasts, and
animal cells, such as CHO, YB/20, NSO, SP2/0, R1.1, B-W and L-M
cells, African Green Monkey kidney cells (e.g., COS 1, COS 7, BSC1,
BSC40, and BMT10), insect cells (e.g., Sf9), and human cells and
plant cells in tissue culture.
[0282] It will be understood that not all vectors, expression
control sequences and hosts will function equally well to express
the DNA sequences. Neither will all hosts function equally well
with the same expression system. However, one skilled in the art
will be able to select the proper vectors, expression control
sequences, and hosts without undue experimentation to accomplish
the desired expression without departing from the scope of this
application. For example, in selecting a vector, the host must be
considered because the vector must function in it. The vector's
copy number, the ability to control that copy number, and the
expression of any other proteins encoded by the vector, such as
antibiotic markers, will also be considered. One of ordinary skill
in the art can select the proper vectors, expression control
sequences, and hosts to accomplish the desired expression without
departing from the scope of this application. For example, in
selecting a vector, the host is considered because the vector
functions in it. The vector's copy number, the ability to control
that copy number, and the expression of any other proteins encoded
by the vector, such as antibiotic markers, can also be
considered.
[0283] The present application also provides constructs in the form
of plasmids, vectors, transcription or expression cassettes as
described elsewhere herein which comprise at least one
polynucleotide as above. Suitable vectors can be chosen or
constructed, containing appropriate regulatory sequences, including
promoter sequences, terminator sequences, polyadenylation
sequences, enhancer sequences, selectable markers and other
sequences as appropriate. Vectors can be plasmids, viral e.g.,
phage, phagemid, etc., as appropriate; For further details see, for
example, Molecular Cloning: a Laboratory Manual: 2nd edition,
Sambrook et al., 1989, Cold Spring Harbor Laboratory Press. Many
known techniques and protocols for manipulation of nucleic acid,
for example in preparation of nucleic acid constructs, mutagenesis,
sequencing, introduction of DNA into cells and gene expression, and
analysis of proteins, are described in detail in Short Protocols in
Molecular Biology, Second Edition, Ausubel et al. eds., John Wiley
& Sons, 1992. The disclosures of Sambrook et al. and Ausubel et
al. are incorporated herein by reference.
[0284] In selecting an expression control sequence, a variety of
factors will normally be considered. These include, for example,
the relative strength of the system, its controllability, and its
compatibility with the particular DNA sequence or gene to be
expressed, particularly as regards potential secondary structures.
Suitable unicellular hosts will be selected by consideration of,
e.g., their compatibility with the chosen vector, their secretion
characteristics, their ability to fold proteins correctly, and
their fermentation requirements, as well as the toxicity to the
host of the product encoded by the DNA sequences to be expressed,
and the ease of purification of the expression products.
[0285] A further aspect provides a host cell containing one or more
polynucleotides as disclosed herein. Yet a further aspect provides
a method of introducing such one or more polynucleotides into a
host cell, any available technique. For eukaryotic cells, suitable
techniques can include, for example, calcium phosphate
transfection, DEAEDextran, electroporation, liposome-mediated
transfection and transduction using retrovirus or other virus (e.g.
vaccinia) or, for insect cells, baculovirus. For bacterial cells,
suitable techniques can include, for example calcium chloride
transformation, electroporation and transfection using
bacteriophages.
[0286] The introduction can be followed by causing or allowing
expression from the one or more polynucleotides, e.g. by culturing
host cells under conditions for expression of one or more
polypeptides from one or more polynucleotides. Inducible systems
can be used and expression induced by addition of an activator.
[0287] In one embodiment, the polynucleotides can be integrated
into the genome (e.g., chromosome) of the host cell. Integration
can be promoted by inclusion of sequences which promote
recombination with the genome, in accordance with standard
techniques. In another embodiment, the nucleic acid is maintained
on an episomal vector in the host cell.
[0288] Methods are provided herein which include using a construct
as stated above in an expression system in order to express a
specific polypeptide.
[0289] Considering these and other factors, a person skilled in the
art will be able to construct a variety of vector/expression
control sequence/host combinations that will express the DNA
sequences on fermentation or in large scale animal culture.
[0290] A polynucleotide encoding an antibody, antigen-binding
fragment, or a binding protein can be prepared
recombinantly/synthetically in addition to, or rather than, cloned.
The polynucleotide can be designed with the appropriate codons for
the antibody, antigen-binding fragment, or a binding protein. In
general, one will select preferred codons for an intended host if
the sequence will be used for expression. The complete
polynucleotide can be assembled from overlapping oligonucleotides
prepared by standard methods and assembled into a complete coding
sequence. See, e.g., Edge, Nature, 292:756 (1981); Nambair et al.,
Science, 223:1299 (1984); Jay et al., J. Biol. Chem., 259:6311
(1984).
[0291] A general method for site-specific incorporation of
unnatural amino acids into proteins is described in Christopher J.
Noren, Spencer J. Anthony-Cahill, Michael C. Griffith, Peter G.
Schultz, Science, 244:182-188 (April 1989). This method can be used
to create analogs with unnatural amino acids.
[0292] As mentioned above, a DNA sequence encoding an antibody or
antigen-binding fragment thereof can be prepared synthetically
rather than cloned. The DNA sequence can be designed with the
appropriate codons for the antibody or antigen-binding fragment
amino acid sequence. In general, one will select preferred codons
for the intended host if the sequence will be used for expression.
The complete sequence is assembled from overlapping
oligonucleotides prepared by standard methods and assembled into a
complete coding sequence. See, e.g., Edge, Nature, 292:756 (1981);
Nambair et al., Science, 223:1299 (1984); Jay et al., J. Biol.
Chem., 259:6311 (1984), each of which is which is incorporated

[0293] The term "adjuvant" refers to a compound or mixture that
enhances the immune response, particularly to an antigen. An
adjuvant can serve as a tissue depot that slowly releases the
antigen and also as a lymphoid system activator that
non-specifically enhances the immune response (Hood et al.,
Immunology, Second Ed., 1984, Benjamin/Cummings: Menlo Park,
Calif., p. 384). Often, a primary challenge with an antigen alone,
in the absence of an adjuvant, will fail to elicit a humoral or
cellular immune response. Previously known and utilized adjuvants
include, but are not limited to, complete Freund's adjuvant (CFA),
incomplete Freund's adjuvant (IFA), saponin, mineral gels such as
aluminum hydroxide, surface active substances such as lysolecithin,
pluronic polyols, polyanions, peptides, oil or hydrocarbon
emulsions, keyhole limpet hemocyanins, dinitrophenol, and
potentially useful human adjuvant such as BCG (Bacille
Calmette-Guerin) and Corynebacterium parvum. Mineral salt adjuvants
include but are not limited to: aluminum hydroxide, aluminum
phosphate, calcium phosphate, zinc hydroxide and calcium hydroxide.
Preferably, the adjuvant composition further comprises a lipid of
fat emulsion comprising about 10% (by weight) vegetable oil and
about 1-2% (by weight) phospholipids. Preferably, the adjuvant
composition further optionally comprises an emulsion form having
oily particles dispersed in a continuous aqueous phase, having an
emulsion forming polyol in an amount of from about 0.2% (by weight)
to about 49% (by weight), optionally a metabolizable oil in an
emulsion-forming amount of up to 15% (by weight), and optionally a
glycol ether-based surfactant in an emulsion-stabilizing amount of
up to about 5% (by weight).
[0294] Antibodies can also be affinity matured using known
selection and/or mutagenesis methods as described above. Affinity
matured antibodies can have an affinity which is two times, five
times, 10 times, 20 times, 30 times or more greater than the
starting antibody (generally murine, rabbit, chicken, humanized or
human) from which the matured antibody is prepared. Apparent
affinities can be determined by methods such as an enzyme linked
immunosorbent assay (ELISA) or any other technique familiar to one
of skill in the art. Avidities can be determined by methods such as
a Scatchard analysis or any other technique familiar to one of
skill in the art. Another technique for measuring apparent binding
affinity familiar to those of skill in the art is a surface plasmon
resonance technique (analyzed on a BIACORE 2000 system) (Liljeblad,
et al., Glyco. J. 2000, 17:323-329). Standard measurements and
traditional binding assays are described by Heeley, R. P., Endocr.
Res. 2002, 28:217-229.
[0295] In one embodiment, an antibody specifically and selectively
binds to the mature or active form of LOX after proteolytic
processing, with a greater binding affinity (e.g., at least about 5
times, at least about 10 times, at least about 50 times, at least
about 100 times, at least about 500 times, or at least about 1000
times greater), than the binding affinity to at least one of: the
preproprotein of human LOX, the secreted human LOX, or other lysyl
oxidase-like or lysyl oxidase-related proteins (e.g., LOXL1, LOXL2,
LOXL3, and LOXL4). In one embodiment, the antibody specifically and
selectively binds to LOX in unprocessed and/or processed (mature)
forms. The mature form of LOX is typically active although, in some
embodiments, unprocessed LOX is also active.
[0296] In another embodiment, an antibody specifically and
selectively binds to the secreted form of LOX, such as a secreted
human LOX after cleavage of the signal peptide, with a greater
binding affinity (e.g., at least about 5 times, at least about 10
times, at least about 50 times, at least about 100 times, at least
about 500 times, or at least about 1000 times greater), than the
binding affinity to at least one of: the preproprotein of human
LOX, the mature or active human LOX, or other lysyl oxidase-like or
lysyl oxidase-related proteins (e.g., LOXL1, LOXL2, LOXL3, and
LOXL4).
[0297] In yet another embodiment, an antibody specifically and
selectively binds to LOXL2 with a greater binding affinity (e.g.,
at least about 5 times, at least about 10 times, at least about 50
times, at least about 100 times, at least about 500 times, or at
least about 1000 times greater) than the binding affinity to at
least one of: human LOX, the mature or active human LOX, the
secreted form of LOX or other lysyl oxidase-like (LOL) or lysyl
oxidase-related proteins (e.g., LOXL1, LOXL3, and LOXL4) in
unprocessed, mature, active and/or secreted products. In one
embodiment, the antibody specifically and selectively binds to
LOXL2 in unprocessed and/or processed (mature) forms. The mature
form of LOXL2 is typically active although, in some embodiments,
unprocessed LOXL2 is also active.
[0298] An antibody can bind to both human LOX or human LOXL2, with
a greater binding affinity (e.g., at least about 5 times, at least
about 10 times, at least about 50 times, at least about 100 times,
at least about 500 times, or at least about 1000 times greater),
than the binding affinity to at least one of: other lysyl
oxidase-like or lysyl oxidase-related proteins (e.g., LOXL1, LOXL3,
and LOXL4).
[0299] Antibodies that bind to enzymes can be competitive
inhibitors, uncompetitive inhibitors or non-competitive inhibitors.
With respect to competitive inhibition, an inhibitor usually bears
structural similarity to substrate. Inhibition will be noticeable
at low substrate concentrations, but can be overcome at high
substrate concentrations. With respect to uncompetitive inhibition,
an inhibitor binds at site that becomes available after substrate
is bound at the active site. Inhibition will be most noticeable at
high substrate concentration. With respect to non-competitive
inhibition, an inhibitor binds at site away from substrate binding
site. Relative inhibition will generally be the same at all
substrate concentrations. The mechanism of action antibodies that
act as competitive inhibitors, uncompetitive inhibitors and
non-competitive inhibitors is illustrated in FIG. 4. Antibodies
described herein can be competitive inhibitors, uncompetitive
inhibitors or non-competitive inhibitors. In one aspect, antibodies
described herein can be non-competitive inhibitors.
[0300] In one aspect, antibodies described herein are
non-competitive inhibitors; that is the antibodies block enzymatic
activity of LOX or LOXL2 regardless of whether or not the enzymes
are bound to substrate (collagen).
[0301] Binding of an antibody to LOX/LOXL2 can (1) reduce or
inhibit uptake or internalization of LOX/LOXL2 (e.g., via integrin
beta 1 or other cellular receptors or proteins) and/or (2) reduce
or inhibit the enzymatic activity of LOX or LOXL2. It is believed
that such an antibody could reduce EMT and thus is useful for the
applications disclosed herein. An antibody described herein can
bind to the proteolytic cleavage site of LOX or LOXL2, thereby
effectively blocking (inhibiting) processing of the LOX or LOXL2 to
reduce the level of active LOX or LOXL2. Such inhibition can occur
through direct binding to LOX or LOXL2 or through indirect
interference including steric hindrance, enzymatic alteration of
LOX or LOXL2, inhibition of transcription or translation,
destabilization of mRNA transcripts, impaired export, processing,
or localization of LOX or LOXL2, and the like.
[0302] Binding of LOX/LOXL2 with other proteins, such as cellular
receptors (e.g., uptake receptor integrin beta1), BTK (burton
agammagloublinemia tyrosine kinase), or other integrins is also
performed using the aforementioned assay, wherein instead of ECM
proteins, cellular receptors (e.g., uptake receptor integrin
beta1), BTK (burton agammagloublinemia tyrosine kinase), or other
integrins are used.
[0303] Those anti-LOX/LOXL2 antibodies that inhibit LOX/LOXL2
binding to ECM proteins, cellular receptors, and integrins, are
selected as candidates for further development. In one embodiment,
anti-LOX/LOXL2 antibodies that inhibit LOX/LOXL2 binding to ECM
proteins, cellular receptors, and integrins, are non-competitive
inhibitors.
[0304] In one embodiment, an antibody described herein specifically
binds to the catalytic domain of LOX. This domain, in the
C-terminal region, contains the elements required for catalytic
activity (the copper binding site, tyrosyl and lysyl residues that
contribute to the carbonyl cofactor, and 10 cysteine residues. See,
Thomassin et al. "The Pro-regions of lysyl oxidase and lysyl
oxidase-like 1 are required for deposition onto elastic fibers," J
Biol. Chem. 2005 Dec. 30; 280(52):42848-55 for further details.
[0305] Provided herein are antibodies or antigen binding fragments
thereof that bind to LOX and/or inhibit the activity of LOX.
Anti-LOX antibodies and antigen binding fragments thereof that bind
and/or inhibit LOX have use in the purification, diagnostic, and
therapeutic methods described herein. Antibodies can bind both
full-length and/or processed LOX/LOXL2.
[0306] Provided herein is an isolated antibody or antigen binding
fragment thereof, comprising a variable heavy chain having at least
75% amino acid sequence identity to an amino acid sequence set
forth as SEQ ID NO: 3 and a variable light chain having at least
75% amino acid sequence identity to an amino acid sequence set
forth as SEQ ID NO: 4 or 5.
[0307] In one aspect, provided herein is an isolated antibody or
antigen binding fragment thereof, comprising a variable heavy chain
having at least 75% amino acid sequence identity to an amino acid
sequence set forth as SEQ ID NO: 3. In another aspect, provided
herein is an isolated antibody or antigen binding fragment thereof,
comprising a variable light chain having at least 75% amino acid
sequence identity to an amino acid sequence set forth as SEQ ID NO:
4 or 5.
[0308] Further provided herein are antibodies or antigen binding
fragments thereof, that compete with, or specifically bind to, an
anti-LOX antibody or antigen binding fragment thereof described
herein for binding to LOX. In one embodiment, anti-LOX antibodies
described herein are non-competitive inhibitors.
[0309] Any of such antibodies or antigen binding fragments can
specifically bind to LOX with a binding affinity of at least 2, 5,
10, 50, 100, 500 or 1000 times greater than to at least one of
LOXL1, LOXL2, LOXL3 or LOXL4.
[0310] In one embodiment, an antibody or antigen binding fragment
thereof, described herein specifically binds both full-length and
processed LOX. In one aspect, both full-length and processed LOX
are active forms of the enzyme.
[0311] Provided herein are antibodies or antigen binding fragments
thereof that bind to LOXL2 and/or inhibit the activity of LOXL2.
Anti-LOXL2 antibodies and antigen binding fragments thereof that
bind and/or inhibit LOXL2 have use in the purification, diagnostic,
and therapeutic methods described herein.
[0312] Provided herein is an isolated antibody or antigen binding
fragment thereof, that specifically binds to an epitope having an
amino acid sequence set forth as SEQ ID NO: 6. The antibody or
antigen binding fragment thereof, can comprise a variable heavy
chain having at least 75% amino acid sequence identity to an amino
acid sequence set forth as SEQ ID NO: 1 and a variable light chain
having at least 75% amino acid sequence identity to an amino acid
sequence set forth as SEQ ID NO: 2.
[0313] Also provided herein is an isolated antibody or antigen
binding fragment thereof, comprising a variable heavy chain having
at least 75% amino acid sequence identity to an amino acid sequence
set forth as SEQ ID NO: 1, and a variable light chain having at
least 75% amino acid sequence identity to an amino acid sequence
set forth as SEQ ID NO: 2.
[0314] In one aspect, provided herein is a variable heavy chain
having at least 75% amino acid sequence identity to an amino acid
sequence set forth as SEQ ID NO: 1. In another aspect, provided
herein is a variable light chain having at least 75% amino acid
sequence identity to an amino acid sequence set forth as SEQ ID NO:
2.
[0315] Further provided herein are antibodies or antigen binding
fragments that compete with, or specifically bind to, any of the
preceding antibodies or antigen binding fragments thereof for
binding to LOXL2.
[0316] Any of such antibodies or antigen binding fragments can
specifically bind to LOXL2 with a binding affinity of at least 2,
5, 10, 50, 100, 500 or 1000 times greater than to at least one of
LOX, LOXL1, LOXL3 or LOXL4.
[0317] In one embodiment, an antibody or antigen binding fragment
thereof, described herein specifically binds to the SRCR3-4 region
of LOXL2 and, thus, binds both full-length and processed LOXL2. In
one aspect, both full-length and processed LOXL2 are active forms
of the enzyme. An antibody can, for example, specifically bind to
an epitope having an amino acid sequence set forth as SEQ ID NO: 6.
Such antibodies can serve as an uncompetitive partial inhibitor of
enzymatic activity in vitro, inhibiting approximately half the
enzymatic activity against a 1,5-diaminopentane substrate with an
apparent IC.sub.50 of 20-30 nM. Such antibodies can serve as
non-competitive inhibitors.
[0318] When humanizing antibodies, simultaneous incorporation of
all of the FR and/or CDR encoding nucleic acids and all of the
selected amino acid position changes can be accomplished by a
variety of methods known to those skilled in the art, including for
example, recombinant and chemical synthesis. For example,
simultaneous incorporation can be accomplished by, for example,
chemically synthesizing the nucleotide sequence for the acceptor
variable region, fused together with the donor CDR encoding nucleic
acids, and incorporating at the positions selected for harboring
variable amino acid residues a plurality of corresponding amino
acid codons.
[0319] Provided herein are antibodies and antigen-binding fragments
thereof that bind to LOX or LOXL2. Antibodies and antigen-binding
fragments thereof that bind LOX or LOXL2 can inhibit (partially or
fully) or manage/treat (partially or fully) symptoms associated
with and/or caused by aberrant LOX or LOXL2 expression. The
application also provides cell lines which can be used to produce
the antibodies, methods for producing the cell lines, methods for
expressing antibodies or antigen-binding fragments and purifying
the same.
[0320] One can recognize that the antibodies and antigen-binding
fragments thereof that specifically bind LOX or LOXL2 generated
using the methods described herein can be tested using the assays
provided herein or known in the art for the ability to bind to LOX
or LOXL2 (e.g., ELISA) as well as affinity (e.g., Biacore or
Surface Plasmon Resonance).
[0321] Humanized versions of anti-LOX and anti-LOXL2 antibodies
have one ore more of the following characteristics: retention of
the inhibitory function of murine monoclonal antibodies, equivalent
or increased binding affinity with a slow off rate (e.g., Kd 0.1-1
nM), binding to full length and/or processed LOX / LOXL2,
non-competitive partial inhibition of enzymatic activity,
equivalent or better Ic50 (e.g., about 30 nM), inhibitory activity
in cell-based migration/invasion assays, inhibition of an EMT-like
change induced by secreted LOX/LOXL2 in conditioned media of tumor
cells, binding to matrix-associated LOX/LOXL2 generated by live
human tumor cells, cross-reactivity of binding of human LOX/LOXL2
with murine LOX/LOXL2, therapeutic effectiveness (e.g., partial or
reduction in tumor size and/or symptoms), reduced toxicity and
reduced immunogenicity.
[0322] Provided herein are humanized antibodies that bind to hLOX,
humanized antibodies that bind to hLOX and mLOX (murine LOX),
humanized antibodies that bind to hLOXL2, and humanized antibodies
that bind to hLOXL2 and mLOXL2 (murine LOXL2). In one aspect, the
humanized antibodies are non-competitive inhibitors.
[0323] In one embodiment, a humanized anti-LOXL2 antibody has VH
chain having an amino acid sequence of SEQ ID NO: 25, SEQ ID NO:
26, SEQ ID NO: 27 or SEQ ID NO: 28. One would understand that
conservative amino acid modifications can be made using the methods
described herein in one or more CDR or framework regions for
affinity maturation of the antibody. Antibodies modified by such
methods can be tested with respect to function using any of the
assays described herein or known in the art.
[0324] In another embodiment, a humanized anti-LOXL2 antibody has
VL chain having an amino acid sequence of SEQ ID NO: 30, SEQ ID NO:
31 dr SEQ ID NO: 32. One would understand that conservative amino
acid modifications can be made using the methods described herein
in one or more CDR or framework regions for affinity maturation of
the antibody. Antibodies modified by such methods can be tested
with respect to function using any of the assays described herein
or known in the art.
[0325] Provided herein is a humanized antibody, or antigen-binding
fragment thereof, which binds LOXL2, comprising a heavy chain
variable region and a light chain variable region, [0326] wherein

[0365] In one embodiment, the antibody, or antigen-binding fragment
thereof, comprises a heavy chain variable region FR1 having an
amino acid sequence as set forth in SEQ ID NO: 33, 37 or 44; a
heavy chain variable region FR2 having an amino acid sequence as
set forth in SEQ ID NO: 34, 38 or 45; a heavy chain variable region
FR3 having an amino acid sequence as set forth in SEQ ID NO: 35,
39, 46, 47 or 48; a heavy chain variable region FR4 having an amino
acid sequence as set forth in SEQ ID NO: 36 or 40; a light chain
variable region FR1 having an amino acid sequence as set forth in
SEQ ID NO: 49 or 53; a light chain variable region FR2 having an

light chain variable region FR3 having an amino acid sequence as
set forth in SEQ ID NO: 51, 55 or 61; and a light chain variable
region FR4 having an amino acid sequence as set forth in SEQ ID NO:
52 or 56.
[0366] Encompassed within the scope of the present application are
variable heavy chains and variable light chains that are at least
50%, 60%, 70%, 75%, 80%,85%, 90%, 95% or up to 100% identical to
the variable heavy chains and variable light chains described
herein.
[0367] Conservative substitutions are minor modification of these
nucleotide sequences and/or amino acids are intended to be included
as heavy and light chain encoding nucleic acids and their
functional fragments. Such minor modifications include, for
example, those which do not change the encoded amino acid sequence
due to the degeneracy of the genetic code as well as those which
result in only a conservative substitution of the encoded amino
acid sequence or those that do not substantially alter the binding
capacity of the antibody. Conservative substitutions of encoded
amino acids include, for example, amino acids which belong within
the following groups: (1) non-polar amino acids (Gly, Ala, Val,
Leu, and Ile); (2) polar neutral amino acids (Cys, Met, Ser, Thr,
Asn, and Gln); (3) polar acidic amino acids (Asp and Glu); (4)
polar basic amino acids (Lys, Arg and His); and (5) aromatic amino
acids (Phe, Trp, Tyr, and His). Other minor modifications are
included within the nucleic acids encoding heavy and light chain
polypeptides of the invention so long as the nucleic acid or
encoded polypeptides retain some, or all, of their function as
described herein and which have use in the methods described
herein. Non-conservative substitutions are those that are not
identified as conservative substitutions. Using the methods
described herein, one can ascertain whether it would be possible to
substitute a non-conservative amino acid for a framework amino acid
residue and test the function of the modified antibody using the
assays described elsewhere herein.
[0368] Modified variable heavy chains and variable light chains can
be screened for binding and activity using methods known in the art
and described herein.
[0369] A substantial portion of a variable domain will include
three CDR regions, together with their intervening framework
regions. The portion can also include at least about 50% of either
or both of the first and fourth framework regions, the 50% being
the C-terminal 50% of the first framework region and the N-terminal
50% of the fourth framework region. Additional residues at the
N-terminal or C-terminal end of the substantial part of the
variable domain may be those not normally associated with naturally
occurring variable domain regions. For example, construction of
humanized anti-LOX or anti-LOXL2 antibodies and antigen-binding
fragments described herein made by recombinant DNA techniques can
result in the introduction of N- or C-terminal residues encoded by
linkers introduced to facilitate cloning or other manipulation
steps. Other manipulation steps include the introduction of linkers
to join variable domains to further protein sequences including
immunoglobulin heavy chains, other variable domains (for example in
the production of diabodies) or protein labels as discussed in more
detail below.
[0370] Antibodies encompassed within the present application,
including, for example, those having variable heavy or light chains
that have at least 50% identity to those described herein can be
assessed for anti-LOX or anti-LOXL2 activity.
[0371] Provided herein is a method for identifying an antibody that
inhibits metastatic tumor cell growth, comprising contacting LOX or
LOXL2 or a cell expressing LOX or LOXL2 with a candidate antibody;
and determining the expression or activity of the LOX or LOXL2,
whereby the candidate antibody that reduces the expression or
activity of LOX or LOXL2 compared to the expression or activity
detected in the absence of the antibody is identified as the
compound that inhibits metastatic tumor cell growth. In particular
embodiments, the antibody is contacted with LOX or LOXL2 or a cell
expressing LOX or LOXL2 under hypoxic conditions. In one aspect,
antibodies described herein can be non-competitive inhibitors.
[0372] Also provided herein is method for identifying an antibody
that increases the efficacy of chemotherapeutic agents, comprising
contacting LOX or LOXL2 or a cell expressing LOX or LOXL2 with a
candidate antibody; and determining the expression or activity of
the LOX or LOXL2, whereby the candidate antibody that reduces the
expression or activity of LOX or LOXL2 compared to the expression
or activity detected in the absence of the antibody is identified
as the antibody that increases the efficacy of chemotherapeutic
agents in inhibiting or reducing metastatic tumor growth.
[0373] Any suitable source of LOX or LOXL2 can be employed as an
antibody target in the present method. The enzyme can be derived,
isolated, or recombinantly produced from any source known in the
art, including yeast, microbial, and mammalian, that will permit
the generation of a suitable product that can generate a detectable
reagent or will be biologically active in a suitable assay.
[0374] The enzymatic activity of LOX or LOXL2 can be assessed by
any suitable method described herein or known in the art. Exemplary
methods of assessing LOX or LOXL2 activity include that of Trackman
et al., Anal. Biochem. 113:336-342 (1981); Kagan, et al., Methods
Enzymol. 82A:637-49 (1982); Palamakumbura et al., Anal. Biochem.
300:245-51 (2002); Albini et al., Cancer Res. 47: 3239-45 (1987);
Kamath et al, Cancer Res. 61:5933-40 (2001); U.S. Pat. No.
4,997,854; and U.S. Patent Application No. 2004/0248871. For
example, enzymatic activity can be assessed by detecting and/or
quantitating "lysyl oxidase byproducts," such as H.sub.2O.sub.2
production; collagen pyridinium residues, ammonium production;
aldehyde product production; lysyl oxidation, deoxypyridinoline
(Dpd)--discussed below. One may also detect and quantitate cellular
invasive capacity in vitro; cellular adhesion and growth in vitro;
and metastatic growth in vivo. In vivo models include, but are not
limited to suitable syngeneic models, human tumor xenograft models,
orthotopic models, metastatic models, transgenic models, and gene
knockout models (see, e.g., Teicher, Tumors Models in Cancer
Research (Humana Press 2001)).
[0375] Hypoxic conditions can be induced or naturally occurring.
Hypoxic areas frequently occur in the interior of solid tumor.
Hypoxia can also be induced in vivo, particularly in experimental
animal models, using diminution or cessation of arterial blood flow
to tumor or the administration of vasoconstrictive compounds. See,
e.g., U.S. Pat. No. 5,646,185. Exemplary vasoconstrictive compounds
include adrenergic direct and indirect agonists such as
norepinephrine, epinephrine, phenylephrine, and cocaine. The
presence of a hypoxic region in a solid tumor present in a subject
can be observed by a number of methods currently known in the art,
including nuclear magnetic resonance (NMR) and oxygen electrode
pO.sub.2 histography. Such methods may be used in the context of
the present invention (as described below), to identify hypoxic
treatment target regions and to guide in administering treatment
compositions to such regions. In vitro, hypoxic conditions can be
induced using any suitable method. For example, cells can be
maintained under anoxic (<0.1% O.sub.2) conditions at 37.degree.
C. within an anaerobic chamber or under hypoxic (1 to 2% O.sub.2)
conditions at 37.degree. C. within a modular incubator chamber
filled with 5% CO.sub.2 and 1 to 2% O.sub.2 balanced with N.sub.2.
See, e.g., Erler et al., Mol. Cell. Biol. 24:2875-89 (2004).
[0376] The LOX or LOXL2 enzymes or LOX- or LOXL2-expressing cell
can be contacted with a compound (e.g., a LOX/LOXL inhibitor such
as an antibody) in any suitable manner for any suitable length of
time. For tumor regions that are accessible to hypodermic delivery
of agent, it may be desirable to inject the compound directly into
the hypoxic region. The cells can be contacted with the compound
more than once during incubation or treatment. Typically, the dose
required for an antibody is in the range of about 1 micro-g/ml to
1000 micro-g/ml, more typically in the range of about 100 .mu.g/ml
to about 800 .mu.g/ml. The exact dose can be readily determined
from in vitro cultures of the cells and exposure of the cell to
varying dosages of the compound. Typically, the length of time the
cell is contacted with the compound is about 5 minutes, about 15
minutes, about 30 minutes, about 1 hour, about 4 hours, about 12
hours, about 36 hours, about 48 hours to about 3 days or more, even
indefinitely, more typically for about 24 hours. For in vitro
invasion assays, any suitable matrix may be used. In one
embodiment, the matrix is reconstituted basement membrane
Matrigel.TM. matrix (BD Sciences).
[0377] Screening methods can also include a step of measuring FAK
levels. As described below, FAK (Focal Adhesion Kinase [p125FAK])
is activated as part of the cell motility process. When LOX is
inhibited, FAK phosphorylation is not increased under hypoxic
conditions. In a compound-screening assay, a secondary step can
include the detection of phospho-FAK levels both with and without
addition of the test antibody. A test inhibitory antibody will also
reduce levels of phospho-FAK.
[0378] An antibody is an inhibitor of LOX or LOXL2 expression or
biological activity when the antibody reduces the expression or
activity or LOX or LOXL2 relative to that observed in the absence
of the antibody. In one embodiment, an antibody is an inhibitor of
LOX or LOXL2 when it reduces the incidence of metastasis relative
to the observed in the absence of the antibody and, in further
testing, inhibits metastatic tumor growth. In one aspect,
antibodies described herein are non-competitive inhibitors. Tumor
inhibition can be quantified using any convenient method of
measurement. The incidence of metastasis can be assessed by
examining relative dissemination (e.g., number of organ systems
involved) and relative tumor burden in these sites. Metastatic
growth can be ascertained by microscopic or macroscopic analysis,
as appropriate. Tumor metastasis can be reduced by about 10%, 20%,
30%, 40%, 50%, 60%, 70%, 80%, 90%, 95% or greater. In some
embodiments, the antibody can be assessed relative to other
antibodies or compounds that do not impact LOX or LOXL2 expression
or biological activity. The test antibodies can be administered at
the time of tumor inoculation, after the establishment of primary
tumor growth, or after the establishment of local and/or distant
metastases. Single or multiple administration of the test antibody
can be given using any convenient mode of administration including,
but not limited to, intravenous, intraperitoneal, intratumoral,
subcutaneous and intradermal.
[0379] Any suitable cell expressing LOX or LOXL2 can be employed
with the present methods. As used herein, the term "cell" includes
a biological cell (e.g., CHO, HeLa, etc.). The cell can be human or
nonhuman. The cell can be freshly isolated (i.e., primary) or
derived from a short term- or long term-established cell line.
Exemplary biological cell lines include MDA-MB 231 human breast
cancer cells, MDA-MB 435 human breast cancer cells, U-87 MG glioma,
SCL1 squamous cell carcinoma cells, CEM, HeLa epithelial carcinoma,
and Chinese hamster ovary (CHO) cells. Such cell lines are
described, for example, in the Cell Line Catalog of the American
Type Culture Collection (ATCC, Rockville, Md.).
[0380] A cell can express the LOX or LOXL2 or its promoter
endogenously or exogenously (e.g., as a result of the stable
transfer of genes). Endogenous expression by a cell as provided
herein can result from constitutive or induced expression of
endogenous genes.
[0381] Exogenous expression by a cell as provided herein can result
from the introduction of the nucleic acid sequences encoding LOX or
LOXL2 or a biologically active fragment thereof, or LOX or LOXL2
promoter nucleic acid sequence. Transformation may be achieved
using viral vectors, calcium phosphate, DEAE-dextran,
electroporation, biolistics, cationic lipid reagents, or any other
convenient technique known in the art. The manner of transformation
useful in the present invention is conventional and is exemplified
in Current Protocols in Molecular Biology (Ausubel, et al., eds.
2000). Exogenous expression of the lysyl oxidase or its promoter
can be transient, stable, or some combination thereof. Exogenous
expression of the enzyme can be achieved using constitutive
promoters, e.g., SV40, CMV, and the like, and inducible promoters
known in the art. Suitable promoters are those that will function
in the cell of interest.
[0382] The methods described herein are non-limiting and any other
methods known in the art can also be used to test the activity of
anti-LOX antibodies and anti-LOXL2 antibodies. Additional assays
are described below in the Examples.
[0383] It may be necessary in some instances to introduce an
unstructured polypeptide linker region between a label of the
present invention and portions of the antibodies. The linker can
facilitate enhanced flexibility, and/or reduce steric hindrance
between any two fragments. The linker can also facilitate the
appropriate folding of each fragment to occur. The linker can be of
natural origin, such as a sequence determined to exist in random
coil between two domains of a protein. An exemplary linker sequence
is the linker found between the C-terminal and N-terminal domains
of the RNA polymerase a subunit. Other examples of naturally
occurring linkers include linkers found in the ICI and LexA
proteins.
[0384] Within the linker, the amino acid sequence may be varied
based on the preferred characteristics of the linker as determined
empirically or as revealed by modeling. Considerations in choosing
a linker include flexibility of the linker, charge of the linker,
and presence of some amino acids of the linker in the
naturally-occurring subunits. The linker can also be designed such
that residues in the linker contact DNA, thereby influencing
binding affinity or specificity, or to interact with other
proteins. In some cases, particularly when it is necessary to span
a longer distance between subunits or when the domains must be held
in a particular configuration, the linker may optionally contain an
additional folded domain.
[0385] In some embodiments it is preferable that the design of a
linker involve an arrangement of domains which requires the linker
to span a relatively short distance, preferably less than about 10
Angstroms (.ANG.). However, in certain embodiments, linkers span a
distance of up to about 50 .ANG..
[0386] Antibodies provided herein such that they are conjugated or
linked to therapeutic and/or imaging/detectable moieties. Methods
for conjugating or linking antibodies are well known in the art.
Associations between antibodies and labels include any means known
in the art including, but not limited to, covalent and non-covalent
interactions.
[0387] In one non-limiting embodiment, antibodies can be associated
with a toxin, a radionuclide, an iron-related compound, a dye, an
imaging reagent, a fluorescent label or a chemotherapeutic agent
that would be toxic when delivered to a cancer cell.
[0388] Alternatively, the antibodies can be associated with
detectable label, such as a radionuclide, iron-related compound, a
dye, an imaging agent or a fluorescent agent for immunodetection of
target antigens.
[0389] Non-limiting examples of radiolabels include, for example,
.sup.32P, .sup.33P, .sup.43K, .sup.52Fe, .sup.57Co, .sup.64Cu,
.sup.67Ga, .sup.67Cu, .sup.68Ga, .sup.71Ge, .sup.75Br, .sup.76Br,

[0390] Non-limiting examples of toxins include, for example,
diphtheria A chain, nonbinding active fragments of diphtheria
toxin, exotoxin A chain (from Pseudomonas aeruginosa), ricin A
chain, abrin A chain, modeccin A chain, alpha-sarcin, Aleurites
fordii proteins, dianthin proteins, Phytolaca americana proteins

perfringens phospholipase C (PLC), bovine pancreatic ribonuclease
(BPR), antiviral protein (PAP), abrin, cobra venom factor (CVF),
gelonin (GEL), saporin (SAP) viscumin.
[0391] Non-limiting examples of iron-related compounds include, for
example, magnetic iron-oxide particles, ferric or ferrous
particles, Fe.sup.203 and Fe.sup.304. Iron-related compounds and
methods of labeling polypeptides, proteins and peptides can be
found, for example, in U.S. Pat. Nos. 4,101,435 and 4,452,773, and
U.S. published applications 20020064502 and 20020136693, all of
which are hereby incorporated by reference in their entirety.
[0392] In certain embodiments, the subject antibodies can be
covalently or non-covalently coupled to a cytotoxin or other cell
proliferation inhibiting compound, in order to localize delivery of
that agent to a tumor cell. For instance, the agent can be selected
from the group consisting agents, enzyme inhibitors, proliferation
inhibitors, lytic agents, DNA or RNA synthesis inhibitors, membrane
permeability modifiers, DNA metabolites, dichloroethylsulfide
derivatives, protein production inhibitors, ribosome inhibitors,
inducers of apoptosis, and neurotoxins.
[0393] In certain embodiments, the subject antibodies can be
coupled with an agent useful in imaging tumors. Such agents
include: metals; metal chelators; lanthanides; lanthanide
chelators; radiometals; radiometal chelators; positron-emitting
nuclei; microbubbles (for ultrasound); liposomes; molecules
microencapsulated in liposomes or nanosphere; monocrystalline iron
oxide nanocompounds; magnetic resonance imaging contrast agents;
light absorbing, reflecting and/or scattering agents; colloidal
particles; fluorophores, such as near-infrared fluorophores. In
many embodiments, such secondary functionality/moiety will be
relatively large, e.g., at least 25 amu in size, and in many
instances can be at least 50,100 or 250 amu in size.
[0394] In certain embodiments, the secondary functionality is a
chelate moiety for chelating a metal, e.g., a chelator for a
radiometal or paramagnetic ion. In additional embodiments, it is a
chelator for a radionuclide useful for radiotherapy or imaging
procedures.
[0395] Radionuclides useful within the present invention include
gamma-emitters, positron-emitters, Auger electron-emitters, X-ray
emitters and fluorescence-emitters, with beta-or alpha-emitters
preferred for therapeutic use. Examples of radionuclides useful as
toxins in radiation therapy include: .sup.32P, .sup.33P, .sup.43K,
.sup.52Fe, .sup.57Co, .sup.64Cu, .sup.67Ga, .sup.67Cu, .sup.68Ga,
.sup.71Ge, .sup.75Br, .sup.76Br, .sup.77Br, .sup.77As, .sup.77Br,
.sup.81Rb/.sup.81MKr, .sup.87MSr, .sup.90Y, .sup.97Ru, .sup.99Tc,
.sup.100Pd, .sup.101Rh, .sup.103Pb, .sup.105Rh, .sup.109Pd,
.sup.111Ag, .sup.111In, .sup.113In, .sup.119Sb, .sup.121Sn,
.sup.123I, .sup.125I, .sup.127Cs, .sup.128Ba, .sup.129Cs,

.sup.199Au, .sup.203Pb, .sup.211At, .sup.212Pb, .sup.212Bi and
.sup.213Bi. Preferred therapeutic radionuclides include .sup.188Re,
.sup.186Re, .sup.203Pb, .sup.212Pb, .sup.212Bi, .sup.109Pd,
.sup.64Cu, .sup.67Cu, .sup.90Y, .sup.125I, .sup.131I, .sup.77Br,
.sup.211At, .sup.97Ru, .sup.105Rh, .sup.198Au and .sup.199Ag,
.sup.166Ho or .sup.177Lu. Conditions under which a chelator will
coordinate a metal are described, for example, by Gasnow et al.
U.S. Pat. Nos. 4,831,175, 4,454,106 and 4,472,509, each of which is
incorporated herein by reference. Within the present invention,
"radionuclide" and "radiolabel" are interchangeable.
[0396] .sup.99Tc is a particularly attractive radioisotope for
diagnostic applications, as it is readily available to all nuclear
medicine departments, is inexpensive, gives minimal patient
radiation doses, and has ideal nuclear imaging properties. It has a
half-life of six hours which means that rapid targeting of a
technetium-labeled antibody is desirable. Accordingly, in certain
preferred embodiments, the modified antibodies include a chelating
agent for technium.
[0397] In still other embodiments, the secondary functionality can
be a radiosensitizing agent, e.g., a moiety that increases the
sensitivity of cells to radiation. Examples of radiosensitizing
agents include nitroimidazoles, metronidazole and misonidazole
(see: DeVita, V. T. in Harrison's Principles of Internal Medicine,
p. 68, McGraw-Hill Book Co., NY, 1983, which is incorporated herein
by reference). The modified antibodies that comprise a
radiosensitizing agent as the active moiety are administered and
localize at the target cell. Upon exposure of the individual to
radiation, the radiosensitizing agent is "excited" and causes the
death of the cell.
[0398] There are a wide range of moieties which can serve as
chelators and which can be derivatized to the antibodies of the
present invention. For instance, the chelator can be a derivative
of 1,4,7,10-tetraazacyclododecanetetraacetic acid (DOTA),
ethylenediaminetetraacetic acid (EDTA),
diethylenetriaminepentaacetic acid (DTPA) and
1-p-Isothiocyanato-benzyl-methyl-diethylenetriaminepentaacetic acid
(ITC-MX). These chelators typically have groups on the side chain
by which the chelator can be used for attachment to subject
antagonists. Such groups include, e.g., benzylisothiocyanate, by
which the DOTA, DTPA or EDTA can be coupled to, e.g., an amine
group.
[0399] In one embodiment, the chelate moiety is an "NxSy" chelate
moiety. As defined herein, the "NxSy chelates" include bifunctional
chelators that are capable of coordinately binding a metal or
radiometal and, preferably, have N2S2 or N3S cores. Exemplary NxSy
chelates are described, e.g., in Fritzberg et al. (1998) PNAS 85:
4024-29; and Weber et al. (1990) Chem. 1: 431-37; and in the
references cited therein.
[0400] Jacobsen et al. (PCT application WO 98/12156) provides
methods and compositions, i.e., synthetic libraries of binding
moieties, for identifying compounds which bind to a metal atom. The
approach described in that publication can be used to identify
binding moieties which can subsequently be added to the antibodies
to derive the modified antibodies.
[0401] One problem frequently encountered with the use of
conjugated proteins in and radiodiagnostic applications is a
potentially dangerous accumulation of the radiolabeled moiety
fragments in the kidney. When the conjugate is formed using an
acid-or base-labile linker, cleavage of the radioactive chelate
from the protein can advantageously occur. If the chelate is of
relatively low molecular weight, as most of the subject modified
antibodies, antigen binding fragments and peptides are expected to
be, it is not retained in the kidney and is excreted in the urine,
thereby reducing the exposure of the kidney to radioactivity.
However, in certain instances, it may be advantageous to utilize
acid- or base-labile in the subject ligands for the same reasons
they have been used in labeled proteins.
[0402] Accordingly, certain of the subject labeled/modified
antibodies can be synthesized, by standard methods in the art, to
provide reactive functional groups which can form acid-labile
linkages with, e.g., a carbonyl group of the ligand. Examples of
suitable acid-labile linkages include hydrazone and
thiosemicarbazone functions. These are formed by reacting the
oxidized carbohydrate with chelates bearing hydrazide,
thiosemicarbazide, and functions, respectively.
[0403] Alternatively, base-cleavable which have been used for the
enhanced clearance of the radiolabel from the kidneys, can be used.
See, for example, Weber et al. 1990 Bioconig. Chem. 1:431. The
coupling of a bifunctional chelate to an antibody via a hydrazide
linkage can incorporate base-sensitive ester moieties in a linker
spacer arm. Such an ester-containing linker unit is exemplified by
ethylene glycolbis (succinimidyl succinate), (EGS, available from
Pierce Chemical Co., Rockford, Ill.), which has two terminal
N-hydroxysuccinimide (NHS) ester derivatives of two 1,4-dibutyric
acid units, each of which are linked to a single ethylene glycol
moiety by two alkyl esters. One NHS ester may be replaced with a
suitable amine-containing BFC (for example 2-aminobenzyl DTPA),
while the other NHS ester is reacted with a limiting amount of
hydrazine. The resulting hyrazide is used for coupling to the
antagonists, forming an ligand-BFC linkage containing two alkyl
ester functions. Such a conjugate is stable at physiological pH,
but readily cleaved at basic pH.
[0404] Antibodies labeled by chelation of radioisotopes are subject
to radiation-induced scission of the chelator and to loss of
radioisotope by dissociation of the coordination complex. In some
instances, metal dissociated from the complex can be re-complexed,
providing more rapid clearance of non-specifically localized
isotope and therefore less toxicity to non-target tissues. For
example, chelator compounds such as EDTA or DTPA can be infused
into patients to provide a pool of chelator to bind released
radiometal and facilitate excretion of free radioisotope in the
urine.
[0405] In still other embodiments, the antibodies are coupled to a
Boron addend, such as a carborane. For example, carboranes can be
prepared with carboxyl functions on pendant side chains, as is well
known in the art. Attachment of such carboranes to amine peptides
can be achieved by activation of the carboxyl groups of the
carboranes and condensation with the amine group to produce the
conjugate. Such modified antibodies can be used for neutron capture
therapy.
[0406] The present invention also contemplates the modification of
the subject antagonists with dyes, for example, useful in therapy,
and used in conjunction with appropriate non-ionizing radiation.
The use of light and porphyrins in methods of the present invention
is also contemplated and their use in cancer therapy has been
reviewed by van den Bergh, Chemistry in Britain, 22: 430-437
(1986), which is incorporated by reference herein in its
entirety.
[0407] One embodiment of the present invention includes antagonists
labeled with a fluorescent label. Common fluorescent labels
include, for example, FITC, PE, Texas Red, cytochrome c, etc.
Techniques for labeling polypeptides and fragments thereof, such as
those provided herein, are well-known in the art.
[0408] The term "anticancer agent" also includes the
chemotherapeutic agents described below. The term anticancer agent
also includes treatment with a substance that reduces hypoxia in a
cell, when such agent is combined with LOX inhibition. Such a
substance may include, e.g., p53. See, e.g., Matoba et al., "p53
Regulates Mitochondrial Respiration," Science 16 Jun. 2006 312:
1650-1653; published online 24 May 2006, and references cited
there. A substance that drives cancer cells towards the respiratory
pathway and away from the glycolytic pathway would be used
advantageously with a LOX inhibitor insofar as LOX would not be
up-regulated in this case.
[0409] Chemotherapeutics useful as active moieties which when
conjugated to antagonists thereof of the present invention are
specifically delivered to cells are typically, small chemical
entities produced by chemical synthesis. Chemotherapeutics include
cytotoxic and cytostatic drugs. Chemotherapeutics may include those
which have other effects on cells such as reversal of the
transformed state to a differentiated state or those which inhibit
cell replication. Examples of known cytotoxic agents useful in the
present invention are listed, for example, in Goodman et al., "The
Pharmacological Basis of Therapeutics," Sixth Edition, A. B. Gilman
et al., eds./Macmillan Publishing Co. New York, 1980. These include
taxanes, such as paclitaxel and docetaxel; nitrogen such as
mechlorethamine, melphalan, uracil mustard and chlorambucil;
ethylenimine derivatives, such as thiotepa; alkyl sulfonates; such
as busulfan; nitrosoureas, such as lomustine, semustine and
streptozocin; triazenes, such as dacarbazine; folic acid analogs,
such as methotrexate; pyrimidine analogs, such as fluorouracil,
cytarabine and azaribine; purine analogs, such as mercaptopurine
and thioguanine; vinca alkaloids, such as vinblastine and
vincristine; antibiotics, such as dactinomycin, daunorubicin,
doxorubicin, and mitomycin; enzymes, such as platinum coordination
complexes, such as cisplatin; substituted urea, such as
hydroxyurea; methyl hydrazine derivatives, such as procarbazine;
adrenocortical suppressants, such as mitotane; hormones and
antagonists, such as adrenocortisteroids (prednisone), progestins
(hydroxyprogesterone caproate, acetate and megestrol acetate),
estrogens (diethylstilbestrol and ethinyl estradiol), and androgens
(testosterone propionate and fluoxymesterone).
[0410] Drugs that interfere with protein synthesis can also be
used; such drugs are known to those skilled in the art and include
puromycin, cycloheximide, and ribonuclease.
[0411] Most of the chemotherapeutic agents currently in use in
treating cancer possess functional groups that are amenable to
chemical cross-linking directly with an amine or carboxyl group of
an agent of the present invention. For example, free amino groups
are available on methotrexate, doxorubicin, daunorubicin,
cytosinarabinoside, bleomycin, fludarabine, and cladribinc while
free carboxylic acid groups are available on methotrexate,
melphalan and chlorambucil.
[0412] These functional groups, that is free amino and carboxylic
acids, are targets for a variety of homobifunctional and
heterobifunctional chemical cross-linking agents which can
crosslink these drugs directly to a free amino group of an
antagonist.
[0413] Chemotherapeutic agents contemplated by the present
invention also include other chemotherapeutic drugs that are
commercially available. Merely to illustrate, the chemotherapeutic
can be an inhibitor of chromatin function, a inhibitor, a
inhibiting drug, a DNA damaging agent, an antimetabolite (such as
folate antagonists, pyrimidine analogs, purine analogs, and
sugar-modified analogs), a DNA synthesis inhibitor, a DNA
interactive agent (such as an intercalating agent), a DNA repair
inhibitor.
[0414] Chemotherapeutic agents may be categorized by their
mechanism of action into, for example, the following groups:
anti-metabolites/anti-cancer agents, such as pyrimidine analogs
floxuridine, capecitabine, and cytarabine) and purine analogs,
folate antagonists and related inhibitors
antiproliferative/antimitotic agents including natural products
such as vinca alkaloid (vinblastine, vincristine, and microtubule
such as taxane (paclitaxel, docetaxel), vinblastin, nocodazole,
epothilones and navelbine, epidipodophyllotoxins (etoposide,
teniposide), DNA damaging agents (actinomycin, amsacrine, busulfan,

melphalan, merchlorehtamine, mitomycin, mitoxantrone, nitrosourea,
procarbazine, taxol, taxotere, teniposide,
triethylenethiophosphoramide and etoposide; antibiotics such as
dactinomycin (actinomycin D), daunorubicin, doxorubicin

plicamycin (mithramycin) and mitomycin; enzymes (L-asparaginase
which systemically metabolizes L-asparagine and deprives cells
which do not have the capacity to synthesize their own asparagine);
antiplatelet agents; antiproliferative/antimitotic alkylating
agents such as nitrogen mustards cyclophosphamide and analogs,
melphalan, chlorambucil), and (hexamethylmelamine and thiotepa),
alkyl nitrosoureas (BCNU) and analogs, streptozocin),
trazenes-dacarbazinine (DTIC); antiproliferative/antimitotic
antimetabolites such as folic acid analogs (methotrexate); platinum
coordination complexes (cisplatin, oxiloplatinim, carboplatin),
procarbazine, hydroxyurea, mitotane, aminoglutethimide; hormones,
hormone analogs (estrogen, tamoxifen, goserelin, bicalutamide,
nilutamide) and aromatase inhibitors (letrozole, anastrozole);
anticoagulants (heparin, synthetic heparin salts and other
inhibitors of thrombin); fibrinolytic agents (such as tissue
plasminogen activator, streptokinase and urokinase), aspirin,
dipyridamole, ticlopidine, clopidogrel; antimigratory agents;
antisecretory agents (breveldin); immunosuppressives tacrolimus
sirolimus azathioprine, mycophenolate; compounds (TNP-470,
genistein) and growth factor inhibitors (vascular endothelial
growth factor inhibitors, fibroblast growth factor inhibitors);
angiotensin receptor blocker, nitric oxide donors; anti-sense
oligonucleotides; antibodies (trastuzumab, rituximab); cell cycle
inhibitors and differentiation inducers (tretinoin); inhibitors,
topoisomerase inhibitors (doxorubicin (adriamycin), daunorubicin,
dactinomycin, eniposide, epirubicin, etoposide, idarubicin,
irinotecan and mitoxantrone, topotecan, irinotecan),
corticosteroids (cortisone, dexamethasone, hydrocortisone,
methylpednisolone, prednisone, and prenisolone); growth factor
signal transduction kinase inhibitors; dysfunction inducers, toxins
such as Cholera toxin, ricin, Pseudomonas exotoxin, Bordetella
pertussis adenylate cyclase toxin, or diphtheria toxin, and caspase
activators; and chromatin. Preferred dosages of the
chemotherapeutic agents are consistent with currently prescribed
dosages.
[0415] Additionally, other labels, such as biotin followed by
streptavidin-alkaline phosphatase (AP), horseradish peroxidase are
contemplated by the present invention.
[0416] As used herein, the terms "nucleic acid damaging treatment"
and "nucleic acid damaging agent" refer to any treatment regimen
that directly or indirectly damages nucleic acid (e.g., DNA, cDNA,
genomic DNA, mRNA, tRNA or rRNA). Examples of such agents include
alkylating agents, nitrosoureas, anti-metabolites, plant alkaloids,
plant extracts and radioisotopes. Examples of agents also include
nucleic acid damaging drugs, for example, 5-fluorouracil (5-FU),
capecitabine, S-1 (Tegafur, 5-chloro-2,4-dihydroxypyridine and
ozonic acid), 5-ethynyluracil, arabinosyl cytosine (ara-C),
5-azacytidine (5-AC), 2',2'-difluoro-2'-deoxycytidine (dFdC),
purine antimetabolites (mercaptopurine, azathiopurine,
thioguanine), gemcitabine hydrochloride (Gemzar), pentostatin,
allopurinol, 2-fluoro-arabinosyl-adenine (2F-ara-A), hydroxyurea,
sulfur mustard (bischloroetyhylsulfide), mechlorethamine,
melphalan, chlorambucil, cyclophosphamide, ifosfamide, thiotepa,
AZQ, mitomycin C, dianhydrogalactitol, dibromoducitol, alkyl
sulfonate (busulfan), nitrosoureas (BCNU, CCNU, 4-methyl CCNU or
ACNU), procarbazine, decarbazine, rebeccamycin, anthracyclins such
as doxorubicin (adriamycin; ADR), daunorubibcin (Cerubicine),
idarubicin (Idamycin) and epirubicin (Ellence), anthracyclin
analogues such as mitoxantrone, actinomycin D, non intercalating
topoisomerase inhibitors such as epipodophyllotoxins
(etoposide=VP16, teniposide=VM-26), podophylotoxin, bleomycin
(Bleo), pepleomycin, compounds that form adducts with nucleic acid
including platinum derivatives (e.g., cisplatin (CDDP), trans
analogue of cisplatin, carboplatin, iproplatin, tetraplatin and
oxaliplatin), camptothecin, topotecan, irinotecan (CPT-11), and
SN-38. Specific examples of nucleic acid damaging treatments
include radiation (e.g., focused microwaves, ultraviolet (UV),
infrared (IR), or alpha-, beta- or gamma-radiation) and
environmental shock (e.g., hyperthermia).
[0417] As used herein, the terms "anti-proliferative treatment" and
"anti-proliferative agent" means any treatment regimen that
directly or indirectly inhibits proliferation of a cell, virus,
bacteria or other unicellular or multicellular organism regardless
of whether or not the treatment or agent damages nucleic acid.
Particular examples of anti-proliferative agents are anti-tumor and
anti-viral drugs, which inhibit cell proliferation or virus
proliferation or replication. Examples include, inter alia,
cyclophosphamide, azathioprine, cyclosporin A, prednisolone,
melphalan, chlorambucil, mechlorethamine, busulphan, methotrexate,
6-mercaptopurine, thioguanine, cytosine arabinoside, taxol,
vinblastine, vincristine, doxorubicin, actinomycin D, mithramycin,
carmustine, lomustine, semustine, streptozotocin, hydroxyurea,
cisplatin, mitotane, procarbazine, dacarbazine and dibromomannitol.
Anti proliferative agents that cause nucleic acid replication
errors or inhibit nucleic acid replication are those such as
nucleoside and nucleotide analogues (e.g., AZT or 5-AZC).
[0418] In another embodiment, the anti-LOX antibody can be
conjugated to a "receptor" (such streptavidin) for utilization in
tumor pre-targeting wherein the antibody-receptor conjugate is
administered to the patient, followed by removal of unbound
conjugate from the circulation using a clearing agent and then
administration of a "ligand" (e.g., avidin) that is conjugated to a
cytotoxic agent (e.g., a radionuclide).
[0419] Methodology for labeling polypeptides and fragments thereof
including, but not limited to,.those provided herein are well known
in the art. When the antibodies of the present invention are
labeled with a radiolabel or toxin, the antibodies can be prepared
as pharmaceutical compositions which are useful for therapeutic
treatment of patients where the pharmaceutical compositions are
administered to the patient in an effective amount. When the
antibodies of the present invention are labeled with a label that
can be visualized, the antibodies can be prepared as pharmaceutical
compositions which are useful for diagnostic of patients where the
pharmaceutical compositions are administered to the patient in an
effective amount for in vivo imaging or where the pharmaceutical
compositions are tested in an in vitro assay.
V. Compositions
[0420] Each of the antibodies of the present invention can be used
as a composition when combined with a pharmaceutically acceptable
carrier or excipient. Such pharmaceutical compositions are useful
for administration to a subject in vivo or ex vivo, and for
diagnosing and/or treating a subject with the disclosed antibodies,
for example.
[0421] Pharmaceutically acceptable carriers are physiologically
acceptable to the administered patient and retain the therapeutic
properties of the antibodies or peptides with which it is
administered. Pharmaceutically-acceptable carriers and their
formulations are and generally described in, for example,
Remington' pharmaceutical Sciences (18.sup.th Edition, ed. A.
Gennaro, Mack Publishing Co., Easton, Pa. 1990). One exemplary
pharmaceutical carrier is physiological saline. The phrase
"pharmaceutically acceptable carrier" as used herein means a
pharmaceutically acceptable material, composition or vehicle, such
as a liquid or solid filler, diluent, excipient, solvent or
encapsulating material, involved in carrying or transporting the
subject antibodies or peptides from the administration site of one
organ, or portion of the body, to another organ, or portion of the
body. Each carrier must be "acceptable" in the sense of being
compatible with the other ingredients of the formulation and not
injurious to the patient. Nor should a pharmaceutically acceptable
carrier alter the specific activity of the antagonists. Exemplary
carriers and excipients have been provided elsewhere herein.
[0422] In one aspect, the present invention provides
pharmaceutically acceptable or physiologically acceptable
compositions including solvents (aqueous or non-aqueous),
solutions, emulsions, dispersion media, coatings, isotonic and
absorption promoting or delaying agents, compatible with
pharmaceutical administration. Pharmaceutical compositions or
pharmaceutical formulations therefore refer to a composition
suitable for pharmaceutical use in a subject. The pharmaceutical
compositions and formulations include an amount of an invention
compound, for example, an effective amount of an antagonist of the
invention, and a pharmaceutically or physiologically acceptable
carrier.
[0423] Pharmaceutical compositions can be formulated to be
compatible with a particular route of administration, systemic or
local. Thus, pharmaceutical compositions include carriers,
diluents, or excipients suitable for administration by various
routes.
[0424] In a further invention, the compositions of the present
invention further comprise a pharmaceutically acceptable additive
in order to improve the stability of the antagonist in composition
and/or to control the release rate of the composition.
Pharmaceutically acceptable additives of the present invention do
not alter the specific activity of the subject antagonist. A
preferable pharmaceutically acceptable additive is a sugar such as
mannitol, sorbitol, glucose, xylitol, trehalose, sorbose, sucrose,
galactose, dextran, dextrose, fructose, lactose and mixtures
thereof. Pharmaceutically acceptable additives of the present
invention can be combined with pharmaceutically acceptable carriers
and/or excipients such as dextrose. Alternatively, a preferable
pharmaceutically acceptable additive is a surfactant such as
polysorbate 20 or polysorbate 80 to increase stability of the
peptide and decrease gelling of the pharmaceutical solution. The
surfactant can be added to the composition in an amount of 0.01% to
5% of the solution. Addition of such pharmaceutically acceptable
additives increases the stability and half-life of the composition
in storage.
[0425] The formulation and delivery methods will generally be
adapted according to the site and the disease to be treated.
Exemplary formulations include, but are not limited to, those
suitable for parenteral administration, e.g., intravenous,
intra-arterial, intramuscular, or subcutaneous administration,
including formulations encapsulated in micelles, liposomes or
drug-release capsules (active agents incorporated within a
biocompatible coating designed for slow-release); ingestible
formulations; formulations for topical use, such as creams,
ointments and gels; and other formulations such as inhalants,
aerosols and sprays. The dosage of the compounds of the invention
will vary according to the extent and severity of the need for
treatment, the activity of the administered composition, the
general health of the subject, and other considerations well known
to the skilled artisan.
[0426] Formulations or enteral (oral) administration can be
contained in a tablet (coated or uncoated), capsule (hard or soft),
microsphere, emulsion, powder, granule, crystal, suspension, syrup
or elixir. Conventional nontoxic solid carriers which include, for
example, pharmaceutical grades of mannitol, lactose, starch,
magnesium stearate, sodium saccharin, talcum, cellulose, glucose,
sucrose, magnesium carbonate, can be used to prepare solid
formulations. Supplementary active compounds (e.g., preservatives,
antibacterial, antiviral and antifungal agents) can also be
incorporated into the formulations. A liquid formulation can also
be used for enteral administration. The carrier can be selected
from various oils including petroleum, animal, vegetable or
synthetic, for example, peanut oil, soybean oil, mineral oil,
sesame oil. Suitable pharmaceutical excipients include e.g.,
starch, cellulose, talc, glucose, lactose, sucrose, gelatin, malt,
rice, flour, chalk, silica gel, magnesium stearate, sodium
stearate, glycerol monostearate, sodium chloride, dried skim milk,
glycerol, propylene glycol, water, ethanol.
[0427] Pharmaceutical compositions for enteral, parenteral, or
transmucosal delivery include, for example, water, saline,
phosphate buffered saline, Hank's solution, Ringer's solution,
dextrose/saline, and glucose solutions. The formulations can
contain auxiliary substances to approximate physiological
conditions, such as buffering agents, tonicity adjusting agents,
wetting agents, detergents and the like. Additives can also include
additional active ingredients such as bactericidal agents, or
stabilizers. For example, the solution can contain sodium acetate,
sodium lactate, sodium chloride, potassium chloride, calcium
chloride, sorbitan monolaurate or triethanolamine oleate.
Additional parenteral formulations and methods are described in Bai
(1997) J. Neuroimmunol. 80:65 75; Warren (1997) J. Neurol. Sci.
152:31 38; and Tonegawa (1997) J. Exp. Med. 186:507 515. The
parenteral preparation can be enclosed in ampules, disposable
syringes or multiple dose vials made of glass or plastic.
[0428] Pharmaceutical compositions for intradermal or subcutaneous
administration can include a sterile diluent, such as water, saline
solution, fixed oils, polyethylene glycols, glycerine, propylene
glycol or other synthetic solvents; antibacterial agents such as
benzyl alcohol or methyl parabens; antioxidants such as ascorbic
acid, glutathione or sodium bisulfite; chelating agents such as
ethylenediaminetetraacetic acid; buffers such as acetates, citrates
or phosphates and agents for the adjustment of tonicity such as
sodium chloride or dextrose.
[0429] Pharmaceutical compositions for injection include aqueous
solutions (where water soluble) or dispersions and sterile powders
for the extemporaneous preparation of sterile injectable solutions
or dispersion. For intravenous administration, suitable carriers
include physiological saline, bacteriostatic water, Cremophor
EL.TM. (BASF, Parsippany, N.J.) or phosphate buffered saline (PBS).
The carrier can be a solvent or dispersion medium containing, for
example, water, ethanol, polyol (for example, glycerol, propylene
glycol, and liquid polyetheylene glycol, and the like), and
suitable mixtures thereof. Fluidity can be maintained, for example,
by the use of a coating such as lecithin, by the maintenance of the
required particle size in the case of dispersion and by the use of
surfactants. Antibacterial and antifungal agents include, for
example, parabens, chlorobutanol, phenol, ascorbic acid and
thimerosal. Isotonic agents, for example, sugars, polyalcohols such
as manitol, sorbitol, and sodium chloride may be included in the
composition. The resulting solutions can be packaged for use as is,
or lyophilized; the lyophilized preparation can later be combined
with a sterile solution prior to administration.
[0430] Pharmaceutically acceptable carriers can contain a compound
that stabilizes, increases or delays absorption or clearance. Such
compounds include, for example, carbohydrates, such as glucose,
sucrose, or dextrans; low molecular weight proteins; compositions
that reduce the clearance or hydrolysis of peptides; or excipients
or other stabilizers and/or buffers. Agents that delay absorption
include, for example, aluminum monostearate and gelatin. Detergents
can also be used to stabilize or to increase or decrease the
absorption of the pharmaceutical composition, including liposomal
carriers. To protect from digestion the compound can be complexed
with a composition to render it resistant to acidic and enzymatic
hydrolysis, or the compound can be complexed in an appropriately
resistant carrier such as a liposome. Means of protecting compounds
from digestion are known in the art (see, e.g., Fix (1996) Pharm
Res. 13:1760 1764; Samanen (1996) J. Pharm. Pharmacol. 48:119 135;
and U.S. Pat. No. 5,391,377, describing lipid compositions for oral
delivery of therapeutic agents).
[0431] For transmucosal or transdermal administration, penetrants
appropriate to the barrier to be permeated are used in the
formulation. Such penetrants are generally known in the art, and
include, for example, for transmucosal administration, detergents,
bile salts, and fusidic acid derivatives. Transmucosal
administration can be through nasal sprays or suppositories (see,
e.g., Sayani (1996) "Systemic delivery of peptides and proteins
across absorptive mucosae" Crit. Rev. Ther. Drug Carrier Syst.
13:85 184). For transdermal administration, the active compound can
be formulated into ointments, salves, gels, or creams as generally
known in the art. Transdermal delivery systems can also be achieved
using patches.
[0432] For inhalation delivery, the pharmaceutical formulation can
be administered in the form of an aerosol or mist. For aerosol
administration, the formulation can be supplied in finely divided
form along with a surfactant and propellant. In another embodiment,
the device for delivering the formulation to respiratory tissue is
in which the formulation vaporizes. Other delivery systems known in
the art include dry powder aerosols, liquid delivery systems,
inhalers, air jet nebulizers and propellant systems (see, e.g.,
Patton (1998) Biotechniques 16:141 143; Dura Pharmaceuticals, San
Diego, Calif.; Aradigm, Hayward, Calif.; Aerogen, Santa Clara,
Calif.; and Inhale Therapeutic Systems, San Carlos, Calif.).
[0433] Biodegradable, biocompatible polymers can be used, such as
ethylene vinyl acetate, polyanhydrides, polyglycolic acid,
collagen, polyorthoesters, and polylactic acid. Methods for
preparation of such formulations are known to those skilled in the
art. The materials can also be obtained commercially from Alza
Corporation and Nova Pharmaceuticals, Inc. Liposomal suspensions
(including liposomes targeted to cells or tissues using antibodies
or viral coat proteins) can also be used as pharmaceutically
acceptable carriers. These can be prepared according to methods
known in the art, for example, as described in U.S. Pat. Nos.
4,235,871; 4,501,728; 4,522,811; 4,837,028; 6,110,490; 6,096,716;
5,283,185; 5,279,833; Akimaru (1995) Cytokines Mol. Ther. 1:197
210; Alving (1995) Immunol. Rev. 145:5 31; and Szoka (1980) Ann.
Rev. Biophys. Bioeng. 9:467). Biodegradable microspheres or
capsules or other biodegradable polymer configurations capable of
sustained delivery of small molecules including peptides are known
in the art (see, e.g., Putney (1998) Nat. Biotechnol. 16:153 157).
Compounds of the invention can be incorporated within micelles
(see, e.g., Suntres (1994) J. Pharm. Pharmacol. 46:23 28; Woodle
(1992) Pharm. Res. 9:260 265). Antagonists can be attached to the
surface of the lipid monolayer or bilayer. For example, antagonists
can be attached to hydrazide-PEG-(distearoylphosphatidy-1)
ethanolamine-containing liposomes (see, e.g., Zalipsky (1995)
Bioconjug. Chem. 6: 705 708). Alternatively, any form of lipid
membrane, such as a planar lipid membrane or the cell membrane of
an intact cell, e.g., a red blood cell, can be used. Liposomal and
lipid-containing formulations can be delivered by any means,
including, for example, intravenous, transdermal (see, e.g., Vutla
(1996) J. Pharm. Sci. 85:5 8), transmucosal, or oral
administration.
[0434] Compositions of the present invention can be combined with
other therapeutic moieties or imaging/diagnostic moieties as
provided herein. Therapeutic moieties and/or imaging moieties can
be provided as a separate composition, or as a conjugated moiety.
Linkers can be included for conjugated moieties as needed and have
been described elsewhere herein.
[0435] The antibodies disclosed herein may also be formulated as
immunoliposomes. Liposomes containing the antibody are prepared by
methods known in the art, such as described in Epstein et al.,
Proc. Natl. Acad. Sci. USA, 82: 3688 (1985); Hwang et al., Proc.
Natl Acad. Sci. USA, 77: 4030 (1980); and U.S. Pat. Nos. 4,485,045
and 4,544,545. Liposomes with enhanced circulation time are
disclosed in U.S. Pat. No. 5,013,556.
[0436] Particularly useful liposomes can be generated by the
reverse-phase evaporation method with a lipid composition
comprising phosphatidylcholine, cholesterol, and PEG-derivatized
phosphatidylethanolamine (PEG-PE). Liposomes are extruded through
filters of defined pore size to yield liposomes with the desired
diameter. Fab' fragments of the antibody of the present invention
can be conjugated to the liposomes as described in Martin et al.,
J. Biol. Chem., 257: 286 288 (1982) via a disulfide-interchange
reaction. A chemotherapeutic agent (such as Doxorubicin) is
optionally contained within the liposome. See Gabizon et al., J.
National Cancer Inst., 81(19): 1484 (1989).
[0437] Lipofections or liposomes can also be used to deliver the
anti-LOX antibody, or an antibody fragment, into cells. Where
antibody fragments are used, the smallest inhibitory fragment that
specifically binds to the binding domain of the target protein can
be used. For example, based upon the variable-region sequences of
an antibody, peptide molecules can be designed that retain the
ability to bind the target protein sequence. Such peptides can be
synthesized chemically and/or produced by recombinant DNA
technology. See, e.g., Marasco et al., Proc. Natl. Acad. Sci. USA,
90: 7889 7893 (1993). The formulation herein can also contain more
than one active compound as necessary for the particular indication
being treated, including, for example, those with complementary
activities that do not adversely affect each other. Alternatively,
or in addition, the composition can comprise an agent that enhances
its function, such as, for example, a cytotoxic agent, cytokine,
chemotherapeutic agent, or growth-inhibitory agent. Such molecules
are suitably present in combination in amounts that are effective
for the purpose intended. The active ingredients can also be
entrapped in microcapsules prepared, for example, by coacervation
techniques or by interfacial polymerization, for example,
hydroxymethylcellulose or gelatin-microcapsules and
poly-(methylmethacylate) microcapsules, respectively, in colloidal
drug delivery systems (for example, liposomes, albumin
microspheres, microemulsions, nano-particles, and nanocapsules) or
in macroemulsions. Such techniques are disclosed in Remington's
Pharmaceutical Sciences, supra.
[0438] Formulations for in vivo administration are sterile.
Sterilization can be readily accomplished via filtration through
sterile filtration membranes.
[0439] Sustained-release preparations can be prepared. Suitable
examples of sustained-release preparations include semipermeable
matrices of solid hydrophobic polymers containing the antibody,
which matrices are in the form of shaped articles, e.g., films, or
microcapsules. Examples of sustained-release matrices include
polyesters, hydrogels (for example,
poly(2-hydroxyethyl-methacrylate), or poly(vinylalcohol)),
polylactides (U.S. Pat. No. 3,773,919), copolymers of L-glutamic
acid and .gamma.-ethyl-L-glutamate, non-degradable ethylene-vinyl
acetate, degradable lactic acid-glycolic acid copolymers such as
the LUPRON DEPOT.RTM. (injectable microspheres composed of lactic
acid-glycolic acid copolymer and leuprolide acetate), and
poly-D-(-)-3-hydroxybutyric acid. While polymers such as
ethylene-vinyl acetate and lactic acid-glycolic acid enable release
of molecules for over 100 days, certain hydrogels release proteins
for shorter time periods. When encapsulated antibodies remain in
the body for a long time, they may denature or aggregate as a
result of exposure to moisture at 37.degree. C., resulting in a
loss of biological activity and possible changes in immunogenicity.
Rational strategies can be devised for stabilization depending on
the mechanism involved. For example, if the aggregation mechanism
is discovered to be intermolecular S--S bond formation through
thio-disulfide interchange, stabilization may be achieved by
modifying sulfhydryl residues, lyophilizing from acidic solutions,
controlling moisture content, using appropriate additives, and
developing specific polymer matrix compositions.
[0440] Various other pharmaceutical compositions and techniques for
their preparation and use will be known to those of skill in the
art in light of the present disclosure. For a detailed listing of
suitable pharmacological compositions and associated administrative
techniques one can refer to the detailed teachings herein, which
can be further supplemented by texts such as Remington: The Science
and Practice of Pharmacy 20th Ed. (Lippincott, Williams &
Wilkins 2003).
[0441] Pharmaceutical compositions contemplated by the present
invention have been described above. In one embodiment of the
present invention, the pharmaceutical compositions are formulated
to be free of pyrogens such that they are acceptable for
administration to human patients. Testing pharmaceutical
compositions for pyrogens and preparing pharmaceutical compositions
free of pyrogens are well understood to one of ordinary skill in
the art.
[0442] One embodiment of the present invention contemplates the use
of any of the pharmaceutical compositions of the present invention
to make a medicament for treating a disorder of the present
invention. Medicaments can be formulated based on the physical
characteristics of the patient/subject needing treatment, and can
be formulated in single or multiple formulations based on the stage
of the cancerous tissue. Medicaments of the present invention can
be packaged in a suitable pharmaceutical package with appropriate
labels for the distribution to hospitals and clinics wherein the
label is for the indication of treating a disorder as described
herein in a subject. Medicaments can be packaged as a single or
multiple units. Instructions for the dosage and administration of
the pharmaceutical compositions of the present invention can be
included with the pharmaceutical packages and kits described
below.
VI. Affinity Purification
[0443] Anti-LOX antibodies and anti-LOXL2 antibodies described
herein are useful for affinity purification of LOX of LOXL2 from
recombinant cell culture, natural sources or tissue biopsy samples
(tissue and/or serum). In this process, antibodies against LOX or
LOXL2 are immobilized on a suitable support, such a Sephadex resin
or filter paper, using methods well known in the art. The
immobilized antibody then is contacted with a sample containing the
LOX or LOXL2 to be purified, and thereafter the support is washed
with a suitable solvent that will remove substantially all the
material in the sample except the LOX or LOXL2, which is bound to
the immobilized antibody. Finally, the support is washed with
another suitable solvent that will release the LOX or LOXL2 from
the antibody.
VII. Packages and Kits
[0444] One embodiment of the present application includes a
pharmaceutical package or kit useful for the methods provided
herein. One embodiment of such pharmaceutical packages or kits
includes preparations (compositions) of the antagonists as provided
herein.
[0445] One aspect of the present invention relates to kits for
carrying out the administration of a LOX/LOXL2 inhibitor. Another
aspect of the present invention relates to kits for carrying out
the combined administration of the LOX/LOXL2 inhibitor with one or
more other therapeutic agent. In one embodiment, the kit comprises
a LOX/LOXL2 inhibitor formulated in a pharmaceutical carrier or
excipient, and at least one therapeutic agent that is not said
LOX/LOXL2 inhibitor, formulated as appropriate, in one or more
separate pharmaceutical preparations.
[0446] Pharmaceutical packages and kits can additionally include an
excipient, a carrier, a buffering agent, a preservative or a
stabilizing agent in a pharmaceutical formulation. Each component
of the kit can be enclosed within an individual container and all
of the various containers can be within a single package. Invention
kits can be designed for room temperature or cold storage.
[0447] Additionally, the preparations can contain stabilizers to
increase the shelf-life of the kits and include, for example,
bovine serum albumin (BSA) or other known conventional stabilizers.
Where the compositions are lyophilized, the kit can contain further
preparations of solutions to reconstitute the preparations.
Acceptable solutions are well known in the art and include, for
example, pharmaceutically acceptable phosphate buffered saline
(PBS).
[0448] Additionally, the pharmaceutical packages or kits provided
herein can further include any of the other moieties provided
herein such as, for example, a chemotherapeutic agent as described
elsewhere in more detail.
[0449] Pharmaceutical packages and kits of the present invention
can further include the components for an assay provided herein,
such as, for example, an ELISA assay. Alternatively, preparations
of the kits are used in immunoassays, such as immunohistochemistry
to test patient tissue biopsy sections. Pharmaceutical packages and
kits of the present invention can further include the components
for collection of a sample.
[0450] Pharmaceutical packages and kits of the present invention
can further include a label specifying, for example, a product
description, mode of administration and indication of treatment.
Pharmaceutical packages provided herein can include any of the
compositions as described herein. The pharmaceutical package can
further include a label for preventing, reducing the risk of, or
treating any of the disease indications described herein.
[0451] The term "packaging material" refers to a physical structure
housing the components of the kit. The packaging material can
maintain the components sterilely, and can be made of material
commonly used for such purposes (e.g., paper, corrugated fiber,
glass, plastic, foil, ampules, etc.). The label or packaging insert
can include appropriate written instructions. Kits of the invention
therefore can additionally include labels or instructions for using
the kit components in any method of the invention. A kit can
include an invention compound in a pack, or dispenser together with
instructions for administering the compound in a method of the
invention.
[0452] Instructions can include instructions for practicing any of
the methods of the invention described herein including treatment,
detection, monitoring or diagnostic methods. Instructions may
additionally include indications of a satisfactory clinical
endpoint or any adverse symptoms that may occur, or additional
information required by regulatory agencies such as the Food and
Drug Administration for use on a human subject.
[0453] The instructions may be on "printed matter," e.g., on paper
or cardboard within or affixed to the kit, or on a label affixed to
the kit or packaging material, or attached to a vial or tube
containing a component of the kit. Instructions may additionally be
included on a computer readable medium, such as a disk (floppy
diskette or hard disk), optical CD such as CD- or DVD-ROM/RAM,
magnetic tape, electrical storage media such as RAM and ROM, IC tip
and hybrids of these such as magnetic/optical storage media.
[0454] The compositions of the kit of the present invention can be
formulated in single or multiple units for either a single test or
multiple tests.
[0455] In preferred embodiments, the preparations of the kit are
free of pyrogens. Methods for testing for the presence of, and/or
specific levels of, pyrogens are routine in the art and kits are
commercially available for such purpose.
[0456] Provided herein is a kit for treating a condition associated
with LOX or LOXL2, containing a composition of an antibody or
antigen binding fragment thereof described herein and a
pharmaceutically acceptable carrier or excipient. A condition
associated with LOX or LOXL2 can be, for example, a tumor, a
metastasis, angiogenesis, or fibrosis. In one embodiment,
antibodies in such kits can comprise a detectable label, a
therapeutic label or both. In another embodiment, antibodies in
such kits can be lyophilized.
[0457] Another aspect of the present invention relates to kits for
carrying out the combined administration of the LOX or LOXL2
inhibitor with other therapeutic compounds. In one embodiment, the
kit comprises a LOX or LOXL2 inhibitor formulated in a
pharmaceutical carrier, and at least one cytotoxic agent,
formulated as appropriate, in one or more separate pharmaceutical
preparations.
VIII. Diagnostic Methods
[0458] The present invention also provides methods for diagnosing,
monitoring, staging or detecting the diseases described above by
using agents that recognize different forms of LOX or LOXL2. For
example, as described above, antibodies against different forms of
LOX or LOXL2, the preproprotein, secreted, mature or active form,
can be used for these purposes. Methods of diagnosing, monitoring,
staging or detecting the diseases described above by using agents
that recognize different forms of LOX or LOXL2 are intended to
encompass all of the diseases and indications described herein.
[0459] As described above, active LOX or LOXL2 is cleaved and can
be detected by virtue of its change in molecular weight
(immunoblot) or by use of antibodies that detect the uncleaved vs.
cleaved form of LOX/LOXL, along with cellular localization by using
various detection methods such as immunohistochemistry (IHC).
[0460] It is believed that the extracellular matrix and conditioned
medium should contain proteolytically processed, active LOX or LOXL
whereas uncleaved, inactive LOX/LOXL should be localized
intracellularly. Some active, cleaved LOX/LOXL can also be detected
inside the cell as a consequence of uptake from the extracellular
space.
[0461] Samples from individuals can be collected and analyzed by
determining inactive or active LOX levels. This analysis can be
performed prior to the initiation of treatment using lysyl
oxidase-specific therapy to identify tumors having elevated active
LOX/LOXL expression or activity. Such diagnosis analysis can be
performed using any sample, including but not limited to cells,
protein or membrane extracts of cells, biological fluids such as
sputum, blood, serum, plasma, or urine, or biological samples such
as tissue samples, formalin-fixed or frozen tissue sections.
[0462] Any suitable method for detection and analysis of inactive
and/or active LOX/LOXL can be employed. As used herein, the term
"sample" refers to a sample from a human, animal, or to a research
sample, e.g., a cell, tissue, organ, fluid, gas, aerosol, slurry,
colloid, or coagulated material. Samples also include, but are not
limited to, protein or membrane extracts of cells, biological
fluids such as sputum, blood, serum, plasma, or urine, or
biological samples such as formalin-fixed or frozen tissue sections
employing antibodies described herein. The term "sample" can also
refer to a cell, tissue, organ, or fluid that is freshly taken from
a human or animal, or to a cell, tissue, organ, or fluid that is
processed or stored. The sample can be tested in vivo, e.g.,
without removal from the human or animal, or it can be tested in
vitro. The sample can be tested after processing, e.g., by
histological methods.
[0463] Various diagnostic assay techniques known in the art can be
used, such as competitive binding assays, direct or indirect
sandwich assays and immunoprecipitation assays conducted in either
heterogeneous or homogeneous phases (Zola, Monoclonal Antibodies: A
Manual of Techniques, CRC Press, Inc. (1987) pp. 147-158). The
antibodies used in the diagnostic assays can be labeled with a
detectable moiety. The detectable moiety directly or indirectly
produces a detectable signal. For example, the detectable moiety
can be any of those described herein such as, for example, a
radioisotope, such as .sup.3H, .sup.14C, .sup.32P, .sup.35S, or
.sup.125I, a fluorescent or chemiluminescent compound, such as
fluorescein isothiocyanate (FITC), Texas red, cyanin, photocyan,
rhodamine, or luciferin, or an enzyme, such as alkaline
phosphatase, .beta.-galactosidase or horseradish peroxidase. Any
method known in the art for conjugating the antibody to the
detectable moiety can be employed, including those methods
described by Hunter et al., Nature, 144:945 (1962); David et al.,
Biochemistry, 13:1014 (1974); Pain et al., J. Immunol. Meth.,
40:219 (1981); and Nygren, J. Histochem. and Cytochem., 30:407
(1982).
[0464] Provided herein is a method of diagnosing a condition
associated with LOX or LOXL2 comprising assessing a level of LOX
and/or LOXL2 in a sample of a subject, wherein a change in level of
LOX and/or LOXL2 in the sample in comparison with a reference
sample indicates the presence or increase of a tumor or metastasis.
In one aspect, the condition associated with LOX or LOXL2 is a
tumor, a metastasis, angiogenesis, or fibrosis. An increase in LOX
and/or LOXL2 levels in the sample in comparison with a reference
sample can indicate the presence of a tumor or metastasis or an
increase in tumor or metastatic growth. The reference sample can be
a sample taken from the subject at an earlier time point or a
sample from another individual. The level of LOX and/or LOXL2
levels in the sample can be detected by contacting the sample with
an antibody or antigen binding fragment thereof described herein.
In one embodiment, the antibody or antigen binding fragment thereof
is detectably labeled.
[0465] In one embodiment, a method is provided for diagnosing
cancer metastasis in a subject, comprising: assessing active LOX or
LOXL2 levels or activity in the blood, whereby a change in active
LOX or LOXL2 levels or activity (e.g., in gene expression,
enzymatic activity, etc.) in the blood in comparison with a
reference sample, indicates the presence of metastatic tumor
growth. In some instances, the active LOX or LOXL2 levels or
activities in the blood can be lower than those when measured
earlier, which can indicate that the subject is at a greater risk
of cancer metastasis; that the cancer has metastasized; or that
cancer metastasis has increased. The reference sample may derive
from the same subject, taken from the same tumor at a different
time point or from other site of the body, or from another
individual.
[0466] In another embodiment, a method is provided for diagnosing
cancer metastasis in a subject having a tumor, comprising:
assessing active LOX or LOXL2 levels or activity in the tumor,
whereby a change in active LOX or LOXL2 levels or activity in the
tumor in comparison with a reference sample indicates the presence
of metastatic tumor growth. In some instances, the active LOX or
LOXL2 levels or activities in the tumor can be higher than those
when measured earlier, which can indicate that the subject is at a
greater risk of cancer metastasis; that the cancer has
metastasized; or that cancer metastasis has increased. The
reference sample can derive from the same subject, taken from the
same tumor at a different time point or from other site of the
body, or from another individual.
[0467] Also provided herein is a method for staging tumor growth or
metastasis in a subject, comprising assessing LOX and/or LOXL2
(e.g., hLOX or hLOXL2) levels in a tumor of the subject, whereby a
change in LOX and/or LOXL2 level (e.g., in gene expression or
enzymatic activity) in the tumor in comparison with a reference
sample, indicates the presence of metastatic tumor growth. In some
instances, the LOX and/or LOXL2 levels or activities in the tumor
may be higher than those when measured earlier for the same
subject, or higher than those in a reference sample taken from a
normal tissue, which may indicate that the patient is at a greater
risk of tumor metastasis; that the tumor has metastasized; or that
tumor metastasis has increased.
[0468] Staging of solid tumor cancers is well known. The TNM system
is one of the most commonly used staging systems. This system has
been accepted by the International Union Against Cancer (UICC) and
the American Joint Committee on Cancer (ADCC). Most medical
facilities use the TNM system as their main method for cancer
reporting. PDQ.RTM., the NCI's comprehensive cancer database, also
uses the TNM system. The TNM system, referred to herein as
"staging," is based on the extent of the tumor, the extent of
spread to the lymph nodes, and the presence of metastasis.
[0469] Also provided here is a method for monitoring a subject's
response to a therapy including a modulator of LOX/LOXL2 such as
the treatment of cancer, tumors, and fibrotic diseases. The method
comprises: detecting a change in the level of C-reactive protein in
the subject after administration of a modulator of LOX or LOXL2 to
the subject, wherein the change indicates that the LOX or LOXL2
modulator has a therapeutic effect on the subject. A C-reactive
protein is an important pharmacodynamic marker for systemic
inflammation. It is believed that a reduced level of C-reactive
protein (e.g., in the blood sample of the subject) as compared to
that prior to the administration of the LOX or LOXL2 inhibitor is
indicative of the subject's response to the therapy using an
inhibitor of LOX or LOXL2.
[0470] Measurement of active LOX or LOXL2 levels can take the form
of an immunological assay, which detects the presence of an active
LOX or LOXL2 protein with an antibody to the protein, preferably an
antibody specifically binding to active LOX or LOXL2.
Antigen-binding fragments of anti-LOX/LOXL antibodies can also be
used.
[0471] Immunoassays also can be used in conjunction with laser
induced fluorescence (see, for example, Schmalzing and Nashabeh,
Electrophoresis 18:2184-93 (1997); and Bao, J. Chromatogr. B.
Biomed. Sci. 699:463-80 (1997), each of which is incorporated
herein by reference). Liposome immunoassays, such as flow-injection
liposome immunoassays and liposome immunosensors also can be used
to determine active LOX or LOXL levels according to a method of the
invention (Rongen et al., J. Immunol. Methods 204:105-133 (1997).
Immunoassays, such as enzyme-linked immunosorbent assays (ELISAs),
can be particularly useful in a method of the invention. A
radioimmunoassay also can be useful for determining whether a
sample is positive for active LOX or LOXL2 or for determining the
level of active LOX or LOXL2. A radioimmunoassay using, for
example, an iodine-125 labeled secondary antibody, can be used.
[0472] In addition, one can measure the activity of active LOX or
LOXL2, thus ignoring the amount of inactive enzyme. Enzymatic
activity of active LOX or LOXL2 can be measured in a number of
ways, using a soluble elastin or soluble collagen with labeled
lysine as a substrate. Details of an activity assay are given in
Royce et al., "Copper metabolism in mottled mouse mutants. The
effect of copper therapy on lysyl oxidase activity in brindled
(Mobr) mice," Biochem J. 1982 Feb. 15; 202(2): 369-371. An
exemplary assay is a chromogenic assay, such as that described by
Palamakumbura, et al. "A fluorometric assay for detection of lysyl
oxidase enzyme activity in biological samples," Anal Biochem. 2002
Jan. 15; 300(2):245-51.
[0473] In addition to measuring the level of LOX or LOXL2 in the
blood (or urine), one can measure secondary products of LOX or
LOXL2 activity. For example, deoxypyridinoline (Dpd) is formed by
the enzymatic action of lysyl oxidase on lysine residues. Dpd is
released into the circulation as a result of osteoclastic
degradation of bone. It cannot be re-used, is cleared by the kidney
and is excreted unchanged in urine. Thus, a test based on the
Immunodiagnostic Systems (IDS) Gamma BCT Dpd assay, using a coated
tube RIA using an anti-Dpd monoclonal antibody can be used to
measure enzymatic activity.
[0474] Anti-LOX antibodies and anti-LOXL2 antibodies described
herein can also be used in the diagnosis of diseases or conditions
associated with aberrant collagen metabolism such as various
fibrotic conditions, for example, lung fibrosis, as well as in
proliferative vitreous retinopathy, surgical scarring, systemic
sclerosis, scleroderma, wound contraction, hypertrophic scars,
fibromatosis (especially Dupuytren's disease), and keloids.
IX. Therapeutic Methods
[0475] The pharmaceutical formulations according to the present
invention can be used to treat a wide variety of diseases and
disorders such as, for example, cancer, metastasis, fibrosis and
aberrant angiogenesis.
[0476] Provided herein is a method of inhibiting LOXL2 by
contacting a sample,or a cellular tissue with any of the anti-LOXL2
antibodies or antigen binding fragments thereof described herein.
Binding of said antibody or antigen binding fragment thereof to
LOXL2 inhibits enzymatic activity of LOXL2.
[0477] Also provided herein is a method of inhibiting LOX by
contacting a sample or cellular tissue with any of the anti-LOX
antibodies or antigen binding fragments thereof described herein.
Binding of said antibody or antigen binding fragment thereof to LOX
inhibits enzymatic activity of LOX.
[0478] In either of such methods, contacting can occur in vitro, in
vivo or ex vivo.
[0479] Inhibition of LOX or LOXL2 can have one or more effects in a
subject such as, for example, reduction in tumor growth, reduction
in angiogenesis, reduction in a fibrotic disease, and/or decreasing
extracellular matrix formation. Fibrotic diseases include, but are
not limited to liver fibrosis, lung fibrosis, kidney fibrosis,
cardiac fibrosis, and scleroderma.
[0480] Provided herein are methods of treating diseases and
disorders associated with aberrant expression of LOX or LOXL2.
Diseases and disorder include, but are not limited to tumors (e.g.,
primary or metastatic), angiogenesis related conditions and
fibrotic conditions.
[0481] As used herein, "prevention" refers to prophylaxis,
prevention of onset of symptoms, prevention of progression of a
disease or disorder associated with fibrosis or correlated with
LOX/LOXL2 activity. As used herein, "treat" or "treatment" means
stasis or a postponement of development of the symptoms associated
a disease or disorder described herein. The terms further include
ameliorating existing uncontrolled or unwanted symptoms, preventing
additional symptoms, and ameliorating or preventing the underlying
metabolic causes of symptoms. Thus, the terms denote that a
beneficial result has been conferred on a mammalian subject with a
disease or symptom, or with the potential to develop such disease
or symptom. A response is achieved when the patient experiences
partial or total alleviation, or reduction of signs or symptoms of
illness, and specifically includes, without limitation,
prolongation of survival. The expected progression-free survival
times can be measured in months to years, depending on prognostic
factors including the number of relapses, stage of disease, and
other factors. Prolonging survival includes without limitation
times of at least 1 month (mo), about at least 2 months (mos.),
about at least 3 mos., about at least 4 mos., about at least 6
mos., about at least 1 year, about at least 2 years, about at least
3 years, or more. Overall survival can also be measured in months
to years. The patient's symptoms can remain static or can
decrease.
[0482] Pharmaceutical compositions of the present invention are
administered in therapeutically effective amounts which are
effective for producing some desired therapeutic effect at a
reasonable benefit/risk ratio applicable to any medical treatment.
For the administration of the present pharmaceutical compositions
to human patients, the pharmaceutical compositions of the present
invention can be formulated by methodology known by one of ordinary
skill in the art to be substantially free of pyrogens such that
they do not induce an inflammatory response.
[0483] As used herein, the term "therapeutically effective amount"
or "effective amount" refers to an amount of a therapeutic agent
that when administered alone or in combination with another
therapeutic agent to a cell, tissue, or subject is effective to
prevent or ameliorate the disease condition or the progression of
the disease. A therapeutically effective dose further refers to
that amount of the compound sufficient to result in amelioration of
symptoms, e.g., treatment, healing, prevention or amelioration of
the relevant medical condition, or an increase in rate of
treatment, healing, prevention or amelioration of such conditions.
When applied to an individual active ingredient administered alone,
a therapeutically effective dose refers to that ingredient alone.
When applied to a combination, a therapeutically effective dose
refers to combined amounts of the active ingredients that result in
the therapeutic effect, whether administered in combination,
serially or simultaneously. For example, when in vivo
administration of an anti-LOX/anti-LOXL2 antibody is employed,
normal dosage amounts can vary from about 10 ng/kg to up to 100
mg/kg of mammal body weight or more per day, preferably about 1
.mu.g/kg/day to 50 mg/kg/day, optionally about 100 .mu.g/kg/day to
20 mg/kg/day, 500 .mu.g/kg/day to 10 mg/kg/day, or 1 mg/kg/day to
10 mg/kg/day, depending upon the route of administration.
[0484] An effective response of the present invention is achieved
when the patient experiences partial or total alleviation or
reduction of signs or symptoms of illness, and specifically
includes, without limitation, prolongation of survival. The
expected progression-free survival times may be measured in months
to years, depending on prognostic factors including the number of
relapses, stage of disease, and other factors. Prolonging survival
includes without limitation times of at least 1 month (mo), about
at least 2 mos., about at least 3 mos., about at least 4 mos.,
about at least 6 mos., about at least 1 year, about at least 2
years, about at least 3 years, or more. Overall survival is also
measured in months to years. The patient's symptoms may remain
static, and the tumor burden may not increase.
[0485] A physician or veterinarian having ordinary skill in the art
can readily determine and prescribe the effective amount (ED50) of
the pharmaceutical composition required. For example, the physician
or veterinarian can start doses of the compounds of the invention
employed in the pharmaceutical composition at levels lower than
that required in order to achieve the desired therapeutic effect
and gradually increase the dosage until the desired effect is
achieved.
[0486] As used herein, the term "subject" means mammalian subjects.
Exemplary subjects include, but are not limited to humans, monkeys,
dogs, cats, mice, rats, cows, horses, goats and sheep. In some
embodiments, the subject has cancer and can be treated with the
agent of the present invention as described below.
[0487] Regardless of the route of administration selected, the
compounds of the present invention, which are used in a suitably
hydrated form, and/or the pharmaceutical compositions of the
present invention are formulated into pharmaceutically acceptable
dosage forms such as described below or by other conventional
methods known to those of skill in the art.
[0488] Actual dosage levels of the active ingredients in the
pharmaceutical compositions of this invention may be varied so as
to obtain an amount of the active ingredient that is effective to
achieve the desired therapeutic response for a particular patient,
composition, and mode of administration, without being toxic to the
patient.
[0489] The selected dosage level will depend upon a variety of
factors including the activity of the particular compound of the
present invention employed, the route of administration, the time
of administration, the rate of excretion of the particular compound
being employed, the duration of the treatment, other drugs,
compounds and/or materials used in combination with the particular
composition employed, the age, sex, weight, condition, general
health and prior medical history of the patient being treated, and
like factors well known in the medical arts.
[0490] In one aspect provided herein, administration of the
antibodies results in an improvement the subject's condition. In
another aspect, administration of the antibodies prevents the
subject's condition from worsening and/or prolongs survival of the
patient.
[0491] The patient can be a mammal such as a human or a non-human.
Such a patient can be symptomatic or asymptomatic.
[0492] Compositions can be administered locally, regionally or
systemically by any suitable route provided herein.
[0493] In one aspect, symptoms of the patient are ameliorated.
Amelioration can be manifested as, for example, reduction in pain,
reduced tumor size, elimination of tumors, prevention of increases
in tumor size or progression or of disease, prevention of formation
of metastasis, or inhibition of metastatic growth, inhibition of
fibrosis, inhibition of angiogenesis, or a combination thereof.
[0494] If needed, for cancer treatments, methods can further
include surgical removal of the cancer and/or administration of an
anti-cancer agent or treatment. Administration of such an
anti-cancer agent or treatment can be concurrent with
administration of the compositions disclosed herein. Anti-cancer
agents have been provided elsewhere herein.
[0495] In one aspect, administration of any of the antibodies
provided herein reduces or eliminates the need for the patient to
undergo surgery or treatment with one or more anti-cancer agents or
treatments.
[0496] Indications that can be treated using the pharmaceutical
formulations of the present invention include those involving
undesirable or uncontrolled cell proliferation. Such indications
include benign tumors, various types of cancers such as primary
tumors and tumor metastasis, restenosis (e.g., coronary, carotid,
and cerebral lesions), hematological disorders, abnormal
stimulation of endothelial cells (atherosclerosis), insults to body
tissue due to surgery, abnormal wound healing, abnormal
angiogenesis, diseases that produce fibrosis of tissue, macular
degeneration, glaucoma; age-related macular degeneration (wet AMD
and dry AMD), atherosclerosis, rheumatoid arthritis, multiple
sclerosis, liver fibrosis, kidney fibrosis, lung fibrosis,
scleroderma, atherosclerosis, and Alzheimer's disease, repetitive
motion disorders, disorders of tissues that are not highly
vascularized, and proliferative responses associated with organ
transplants.
[0497] Liver fibrosis includes, but is not limited to, cirrhosis,
and associated conditions such as chronic viral hepatitis,
non-alcoholic fatty liver disease (NAFLD), alcoholic
steatohepatitis (ASH), non-alcoholic steatohepatitis (NASH),
primary biliary cirrhosis (PBC), biliary cirrhosis, and autoimmune
hepatitis.
[0498] Lung fibrosis includes, but is not limited to, idiopathic
pulmonary fibrosis (IPF) or cryptogenic fibrosing alveolitis,
chronic fibrosing interstitial pneumonia, interstitial lung disease
(ILD), diffuse parenchymal lung disease (DPLD), emphysema and
chronic obstructive pulmonary disease (COPD), and chronic
asthma.
[0499] Cardiac fibrosis includes, but is not limited to, congestive
heart failure, cardiomyopathy, and post-myocardial infarction
defects in heart function.
[0500] Kidney fibrosis includes, but is not limited to, diabetic
nephropathy, vesicoureteral reflux, tubulointerstitial renal
fibrosis; glomerulonephritis or glomerular nephritis, including
focal segmental glomerulosclerosis and membranous
glomerulonephritis, and Mesangiocapillary glomerular nephritis.
[0501] Generally, cells in a benign tumor retain their
differentiated features and do not divide in a completely
uncontrolled manner. A benign tumor is usually localized and
non-metastatic. Specific types benign tumors that can be treated
using the present invention include hemangiomas, hepatocellular
adenoma, cavernous haemangioma, focal nodular hyperplasia, acoustic
neuromas, neurofibroma, bile duct adenoma, bile duct cystanoma,
fibroma, lipomas, leiomyomas, mesotheliomas, teratomas, myxomas,
nodular regenerative hyperplasia, trachomas, pyogenic granulomas,
moles, uterine fibroids, thyroid adenomas, adrenocortical adenomas,
and pituitary adenomas.
[0502] In a malignant tumor cells become undifferentiated, do not
respond to the body's growth control signals, and multiply in an
uncontrolled manner. The malignant tumor is invasive and capable of
spreading to distant sites (metastasizing). Malignant tumors are
generally divided into two categories: primary and secondary.
Primary tumors arise directly from the tissue in which they are
found. A secondary tumor, or metastasis, is a tumor which is
originated elsewhere in the body but has now spread to a distant
organ. The common routes for metastasis are direct growth into
adjacent structures, spread through the vascular or lymphatic
systems, and tracking along tissue planes and body spaces
(peritoneal fluid, cerebrospinal fluid, etc.)
[0503] Specific types of cancers or malignant tumors, either
primary or secondary, that can be treated using this invention
include, but are not limited to, lung cancer (including lung
adenocarcinoma, squamous cell carcinoma, large cell carcinoma,
bronchioloalveolar carcinoma, non-small-cell carcinoma, small cell
carcinoma, mesothelioma); breast cancer (including ductal
carcinoma, lobular carcinoma, inflammatory breast cancer, clear
cell carcinoma, mucinous carcinoma,); colorectal cancer (colon
cancer, rectal cancer); anal cancer; pancreatic cancer (including
pancreatic adenocarcinoma, islet cell carcinoma, neuroendocrine
tumors); prostate cancer; ovarian carcinoma (ovarian epithelial
carcinoma or surface epithelial-stromal tumour including serous
tumour, endometrioid tumor and mucinous cystadenocarcinoma,
sex-cord-stromal tumor); liver and bile duct carcinoma (including
hepatocelluar carcinoma, cholangiocarcinoma, hemangioma);
esophageal carcinoma (including esophageal adenocarcinoma and
squamous cell carcinoma); non-Hodgkin's lymphoma; bladder
carcinoma; carcinoma of the uterus (including endometrial
adenocarcinoma, uterine papillary serous carcinoma, uterine
clear-cell carcinoma, uterine sarcomas and leiomyosarcomas, mixed
mullerian tumors); glioma, glioblastoma, medullablastoma, and other
tumors of the brain; kidney cancers (including renal cell
carcinoma, clear cell carcinoma, Wilm's tumor); cancer of the head
and neck (including squamous cell carcinomas); cancer of the
stomach (stomach adenocarcinoma, gastrointestinal stromal tumor);
multiple myeloma; testicular cancer; germ cell tumor;
neuroendocrine tumor; cervical cancer; carcinoids of the
gastrointestinal tract, breast, and other organs; signet ring cell
carcinoma; mesenchymal tumors including sarcomas, fibrosarcomas,
haemangioma, angiomatosis, haemangiopericytoma, pseudoangiomatous
stromal hyperplasia, myofibroblastoma, fibromatosis, inflammatory
myofibroblastic tumour, lipoma, angiolipoma, granular cell tumour,
neurofibroma, schwannoma, angiosarcoma, liposarcoma,
rhabdomyosarcoma, osteosarcoma, leiomyoma or a leiomysarcoma.
[0504] The term "metastasis" means the ability of tumor cells to
invade host tissues and metastasize to distant, often specific
organ sites. As is known, this is the salient feature of lethal
tumor growths. Metastasis formation occurs via a complex series of
unique interactions between tumor cells and normal host tissues and
cells. In the context of the present invention, lysyl oxidase
activity is critical in the metastatic growth of tumors, i.e., the
growth of metastases, particularly under hypoxic conditions. As
hypoxic tumors are also the most aggressive and resistant to
traditional chemotherapy, agents modulating lysyl oxidase
expression and/or function provide a novel therapy against
metastatic tumors, particularly chemo-resistant tumors.
"Metastasis" is distinguished from invasion. As described in
"Understanding Cancer Series: Cancer," in the world wide web site:
cancer.gov/cancertopics/understandingcancer/cancer; invasion refers
to the direct migration and penetration by cancer cells into
neighboring tissues.
[0505] Hematologic disorders include abnormal growth of blood cells
which can lead to dysplastic changes in blood cells and hematologic
malignancies such as various leukemias. Examples of hematologic
disorders include but are not limited to acute myeloid leukemia,
acute promyelocytic leukemia, acute lymphoblastic leukemia, chronic
myelogenous leukemia, the myelodysplastic syndromes, and sickle
cell anemia.
[0506] Acute myeloid leukemia (AML) is the most common type of
acute leukemia that occurs in adults. Several inherited genetic
disorders and immunodeficiency states are associated with an
increased risk of AML. These include disorders with defects in DNA
stability, leading to random chromosomal breakage, such as Bloom's
syndrome, Fanconi's anemia, Li-Fraumeni kindreds,
ataxia-telangiectasia, and X-linked agammaglobulinemia.
[0507] Acute promyelocytic leukemia (APML) represents a distinct
subgroup of AML. This subtype is characterized by promyelocytic
blasts containing the 15; 17 chromosomal translocation. This
translocation leads to the generation of the fusion transcript
comprised of the retinoic acid receptor and a sequence PML.
[0508] Acute lymphoblastic leukemia (ALL) is a heterogenerous
disease with distinct clinical features displayed by various
subtypes. Reoccurring cytogenetic abnormalities have been
demonstrated in ALL. The most common cytogenetic abnormality is the
9; 22 translocation. The resultant Philadelphia chromosome
represents poor prognosis of the patient.
[0509] Chronic myelogenous leukemia (CML) is a clonal
myeloproliferative disorder of a pluripotent stem cell. CML is
characterized by a specific chromosomal abnormality involving the
translocation of chromosomes 9 and 22, creating the Philadelphia
chromosome. Ionizing radiation is associated with the development
of CML.
[0510] The myelodysplastic syndromes (MDS) are heterogeneous clonal
hematopoietic stem cell disorders grouped together because of the
presence of dysplastic changes in one or more of the hematopoietic
lineages including dysplastic changes in the myeloid, erythroid,
and megakaryocytic series. These changes result in cytopenias in
one or more of the three lineages. Patients afflicted with MDS
typically develop complications related to anemia, neutropenia
(infections), or thrombocytopenia (bleeding). Generally, from about
10% to about 70% of patients with MDS develop acute leukemia.
[0511] Administration of LOX or LOX2 inhibitors has been found to
reduce the size of existing tumors, to prevent metastases, and to
reduce the size of (or even eliminate) existing metastases (see,
e.g., Molnar et al. (2003) Biochim Biophys. Acta.
1647:220-224).
[0512] Provided herein is a method of reducing tumor growth in a
subject, by administering any of the anti-LOX or anti-LOXL2
antibodies or antigen binding fragments thereof described herein.
In one embodiment, a tumor is a primary tumor. In another
embodiment, a tumor is a metastatic tumor. Metastatic tumor burden
of a subject can stabilized by administering antibodies as
described herein. Tumor in the subject can be reduced by at least
10%, 25%, 50%, 70%, 90%, 95%, or more as compared to the tumor in
the subject prior to treatment.
[0513] When an antibody or antigen binding fragment thereof
specifically binds to LOXL2, examples of tumors include, but are
not limited to, a colon tumor, an esophageal tumor, a breast tumor,
a prostate tumor, a squamous carcinoma or a spindle cell
carcinoma.
[0514] When an antibody or antigen binding fragment thereof
specifically binds to LOX, examples of tumors include, but are not
limited to, a breast tumor, a lung tumor, a kidney tumor, a uterine
tumor, a liver tumor, or a head and neck tumor.
[0515] Provided herein is a method for preventing or reducing tumor
growth, metastatic tumor growth, in a subject in vivo, comprising
administering to a subject in need thereof an effective amount of
an inhibitor of LOX or LOXL2 activity; and optionally, a
pharmaceutically acceptable carrier or excipient, thereby
preventing or reducing tumor growth, for example by at least 25%,
50%, 75%, 90%, or 95%, in the subject treated. A detailed
description of suitable compositions for use in the present
treatment methods is given above. Such methods are useful, for
example, when the tumor is hypoxic. Hypoxic tumors can be readily
identified using routine methods in the art. See, e.g., U.S. Pat.
No. 5,674,693.
[0516] Also, provided herein is a method of treating metastasis in
a subject with cancer in vivo, comprising administering to a
subject in need thereof an effective amount of a LOX or LOXL2
inhibitor, thereby inhibiting metastasis, for example, by at least
25%, 50%, 75%, 90%, or 95%, in the subject treated. In one
embodiment, inhibitors specifically inhibit human LOX or human
LOXL2. Antibodies to be used in these methods have been described
above. The antibody may be desirable to minimize cross-reactions
with other members of the LOX or LOXL2 families and, thus, reduce
the potential adverse side effects due to complications and normal
tissue toxicity.
[0517] Also provided herein is a method of increasing or enhancing
the chances of survival of a subject with metastatic tumor,
comprising administering to a subject in need thereof an effective
amount of an anti-LOX antibody or an anti-LOXL2 antibody, thereby
increasing or enhancing the chances of survival of the subject
treated by a certain period of time, for example, by at least 10
days, 1 month, 3 months, 6 months, 1 year, 1.5 years, 2 years, 3
years, 4 years, 5 years, 8 years, 10 years, or more. The increase
in survival of a subject can be defined, for example, as the
increase in survival of a preclinical animal model of cancer
metastases (e.g., a mouse with metastatic cancer), by a certain
period of time, for example, by at least 10 days, 1 month, 3
months, 6 months, or 1 year, or at least 2 times, 3 times, 4 times,
5 times, 8 times, or 10 times, more than a control animal model
(that has the same type of metastatic cancer) without the treatment
with the inventive method. Alternatively, the increase in survival
of a mammal can also be defined, for example, as the increase in
survival of a patient with cancer metastases by a certain period of
time, for example, by at least 10 days, 1 month, 3 months, 6
months, 1 year, 1.5 years, 2 years, 3 years, 4 years, 5 years, 8
years, 10 years or more than a patient with the same type of
metastatic cancer but without the treatment with the inventive
method. The control patient may be on a placebo or treated with
supportive standard care such as chemical therapy, biologics and/or
radiation that do not include the inventive method as a part of the
therapy.
[0518] Also provided herein is a method of stabilizing metastatic
tumor burden of a subject, comprising administering to a subject in
need thereof an effective amount of an anti-LOX antibody or an
anti-LOXL2 antibody, thereby stabilizing metastatic tumor burden of
a subject for a certain period of time, for example, for at least
10 days, 1 month, 3 months, 6 months, 1 year, 1.5 years, 2 years, 3
years, 4 years, 5 years, 8 years, 10 years or more. Stabilization
of the metastatic tumor burden of a subject can be defined as
stabilization of metastatic tumor burden of a preclinical animal
model with metastatic tumor burden (e.g., a mouse with metastatic
tumor) for a certain period of time, for example, for at least 10
days, 1 month, 3 months, 6 months, or 1 year more than a control
animal model (that has the same type of metastatic tumor) without
the treatment with the inventive method.
[0519] The present treatment methods also include a method to
increase the efficacy of chemotherapeutic agents, comprising
administering to a subject in need thereof an effective amount of
an anti-LOX antibody or an anti-LOXL2 antibody: and optionally, a
pharmaceutically acceptable carrier or excipient, thereby
increasing the efficacy of chemotherapeutic agents (which are
described in more detail above). Also contemplated are methods
involving the delivery of LOX inhibitory formulations in
combination with radiation therapy. Radiation therapy may be used
to treat almost every type of solid tumor, including cancers of the
brain, breast, cervix, larynx, lung, pancreas, prostate, skin,
spine, stomach, uterus, or soft tissue sarcomas. Radiation can also
be used to treat leukemia and lymphoma (cancers of the
blood-forming cells and lymphatic system, respectively). Radiation
dose to each site depends on a number of factors, including the
type of cancer and whether there are tissues and organs nearby that
may be damaged by radiation. Radiation will typically be delivered
as X-rays, where the dosage is dependent on the tissue being
treated. Radiopharmaceuticals, also known as radionucleotides, may
also be used to treat cancer, including thyroid cancer, cancer that
recurs in the chest wall, and pain caused by the spread of cancer
to the bone (bone metastases). Radionuclides have been described in
more detail above.
[0520] The subject to be treated or diagnosed by the present
methods includes a subject having or being at risk of having
metastatic tumor growth. Such tumors can be a In one aspect, a
tumor is, for example, Lung cancer (including lung adenocarcinoma,
squamous cell carcinoma, large cell carcinoma, bronchioloalveolar
carcinoma, non-small-cell carcinoma, small cell carcinoma,
mesothelioma); breast cancer (including ductal carcinoma, lobular
carcinoma, inflammatory breast cancer, clear cell carcinoma,
mucinous carcinoma,); colorectal cancer (colon cancer, rectal

neuroendocrine tumor; cervical cancer; carcinoids of the
gastrointestinal tract, breast, and other organs; signet ring cell
carcinoma; mesenchymal tumors including sarcomas, fibrosarcomas,
haemangioma, angiomatosis, haemangiopericytoma, pseudoangiomatous
stromal hyperplasia, myofibroblastoma, fibromatosis, inflammatory
myofibroblastic tumour, lipoma, angiolipoma, granular cell tumour,
neurofibroma, schwannoma, angiosarcoma, liposarcoma,
rhabdomyosarcoma, osteosarcoma, leiomyoma or a leiomysarcoma. In
one non-limiting embodiment, the tumor is a breast tumor, a
pancreas tumor, a lung tumor, a cervical tumor, a colon tumor or a
head and neck tumor.
[0521] The present invention also provides a method for preventing
or reducing the risk of tumor metastasis in a subject, comprising
administering to a subject in need thereof an effective amount of
an anti-LOX antibody or an anti-LOXL2 antibody; and optionally, a
pharmaceutically acceptable carrier or excipient, thereby
preventing or reducing preventing or reducing the risk of tumor
metastasis. The inhibitor can be an antibody or an antigen binding
fragment thereof. The subject in need of such a prophylactic can be
an individual who is genetically predisposed to cancer or at a high
risk of developing cancer due to various reasons such as family
history of cancer and carcinogenic environment.
[0522] Examples of the human gene that is involved in the onset or
development of cancer include, but are not limited to, VHL (the Von
Hippon Landau gene involved in Renal Cell Carcinoma); P16/INK4A
(involved in lymphoma); E-cadherin (involved in metastasis of
breast, thyroid, gastric cancer); hMLH1 (involved in DNA repair in
colon, gastric, and endometrial cancer); BRCA1 (involved in DNA
repair in breast and ovarian cancer); LKB1 (involved in colon and
breast cancer); P15/INK4B (involved in leukemia such as AML and
ALL); ER (estrogen receptor, involved in breast, colon cancer and
leukemia); 06-MGMT (involved in DNA repair in brain, colon, lung
cancer and lymphoma); GST-pi (involved in breast, prostate, and
renal cancer); TIMP-3 (tissue metalloprotease, involved in colon,
renal, and brain cancer metastasis); DAPK1 (DAP kinase, involved in
apoptosis of B-cell lymphoma cells); P73 (involved in apoptosis of
lymphomas cells); AR (androgen receptor, involved in prostate

Intern. Med. 134:573-586, which is herein incorporated by reference
in its entirety. Nucleotide sequences of these genes can be
retrieved from the website of the National Center for Biotechnology
Information (NCBI).
[0523] It should be noted that, although leukemia is a cancer of
the blood, it might affect other organs, or, in effect,
metastasize. In acute leukemias, the abnormal cells may collect in
the central nervous system, the testicles, the skin and any other
organ in the body. Because leukemia already involves all of the
bone marrow in the body, and in many cases, has spread to other
organs such as the liver, spleen, and lymph nodes, the staging of
leukemia depends on other information that reflects the patient's
outlook for survival. Leukemias include, for example, Acute
lymphoblastic leukemia (ALL), Chronic lymphocytic leukemia (CLL),
Acute myelogenous leukemia (AML), Chronic myelogenous leukemia
(CML) and Hairy cell leukemia (HCL). Different staging systems are
used for different types of chronic leukemia. Some types do not
have any staging system. Methods of staging are described in more
detail below.
[0524] Treatment of abnormal cell proliferation due to insults to
body tissue during surgery can be possible for a variety of
surgical procedures, including joint surgery, bowel surgery, and
keloid scarring. Diseases that produce fibrotic tissue include
emphysema. Repetitive motion disorders that can be treated using
the present invention include carpal tunnel syndrome. An example of
cell proliferative disorders that can be treated using the
invention is a bone tumor. Provided herein is a method for
preventing or reducing the risk of abnormal cell proliferation due
to insults to body tissue during surgery or a disease that produces
fibrotic tissue in a subject, comprising administering to a subject
in need thereof an effective amount of an anti-LOX antibody or an
anti-LOXL2 antibody; and optionally, a pharmaceutically acceptable
carrier or excipient, thereby preventing or reducing abnormal cell
proliferation due to insults to body tissue during surgery. The
inhibitor can be an antibody or an antigen binding fragment
thereof. The subject in need of such a prophylactic can be an
individual who is genetically predisposed to cancer or at a high
risk of developing cancer due to various reasons such as family
history of cancer and carcinogenic environment. In one embodiment,
the disease can be, for example, joint surgery, bowel surgery,
keloid scarring, a disease that produces fibrotic tissue,
repetitive motion disorders of a bone tumor.
[0525] The proliferative responses associated with organ
transplantation that can be treated using this invention include
those proliferative responses contributing to potential organ
rejections or associated complications. Specifically, these
proliferative responses can occur during transplantation of the
heart, lung, liver, kidney, and other body organs or organ systems.
Provided herein is a method of treating an abnormal proliferative
response associated with organ transplantation, comprising
administering to a subject in need thereof an effective amount of
an anti-LOX antibody or an anti-LOXL2 antibody; and optionally, a
pharmaceutically acceptable carrier or excipient, thereby
preventing or reducing abnormal cell proliferation due to organ
transplantation. Transplantation can include, for example,
transplant of heart, lung, liver, kidney, and other body organs or
organ systems.
[0526] The indication for the inventive composition also includes
fibrosis. Fibrosis results from abnormal accumulation of fibrous
tissue that can occur as a part of the wound-healing process in
damaged tissue. Such tissue damage may result from physical injury,
inflammation, infection, exposure to toxins, and other causes.
Examples of fibrosis include liver fibrosis, lung fibrosis, kidney
fibrosis, cardiac fibrosis and scleroderma. The compounds and
agents of the described invention are also contemplated for the
treatment, prevention, and/or amelioration of fibrotic
conditions.
[0527] Fibrotic tissues accumulate in the heart and blood vessels
as a result of hypertension, hypertensive heart disease,
atherosclerosis, and myocardial infarction. High blood pressure,
or.sub.shypertension, can be cause by a variety of factors and
often leads to the development of Hypertensive Heart Disease (HHD)
with progression to cardiac arrest and myocardial infarction.
Similarly, atherosclerosis and other ischemic heart diseases often
also result in cardiac arrest. These cardiovascular diseases all
exhibit an accumulation of extra-cellular matrix or fibrotic
deposition which results in stiffening of the vasculature and
stiffening of the cardiac tissue itself. This deposition of
fibrotic material is a response to the damage induced by the
hypertensive and/or sclerotic state, but the effects of this
response also result in the negative effects of vascular and
cardiac stiffening as well as ventricle enlargement. Additionally,
it is believed that the increased cardiac fibrosis seen in
cardiovascular disease disrupts or alters the signals transmitted
to cardiomyocytes via the tissue scaffolding of the heart, further
leading to disruption of efficient cardiac function and promoting
cardiac arrest and myocardial infarction. Given the identified role
of increased extracellular matrix deposition in cardiac fibroses,
the compounds of the present invention are useful for the
prevention, treatment, and/or amelioration of cardiac fibroses by
the inhibition of LOX/LOXL2.
[0528] The prevent invention also provides compositions, methods,
systems, medical devices or kits for the treatment or prevention of
cardiac fibrosis associated with cardiovascular diseases such as
hypertensive heart disease (HHD), myocardial infarction (MI),
atherosclerosis, restenosis (e.g. coronary, carotid, and cerebral
lesions), and heart disease associated with cardiac ischemic
events.
[0529] The post MI-healing response can induce expression of
LOX/LOXL2 but if this process continues unchecked, excessive
cross-linking leads to extracellular matrix remodeling or fibrosis
that results in cardiac dysfunction. The enzymes that break down
matrices and cross-linked collagen or elastin appear to function
more slowly or less efficiently and are outpaced by the
cross-linking events. As LOX/LOXL2 also plays a role in
epithelial-mesenchymal transition (EMT), this contributes further
to cardiomyocyte remodeling and cardiomyocyte hypertrophy, in
addition to matrix remodeling.
[0530] Initial reparative fibrosis induced by the MI may be helpful
(e.g., prevents aneurysm and related damage) and can be allowed to
proceed unhindered. However, while not wishing to be bound to a
particular theory or mechanism of action, the inventors believe
that anti-LOX/LOXL2 treatment initiated following this reparative
fibrosis phase could attenuate reactive (mal-adaptive) fibrosis
that leads to cardiac dysfunction. For example, anti-LOX/LOXL2
treatment can be initiated 2, 4, 6, 8, 10, 12, 14, 16, 16, 20, 22,
24, 36, or 48 hours after MI, inclusive of all integers in-between.
Additionally, anti-LOX/LOXL2 treatment can be initiated 2, 3, 4, 5,
6, 7, 8, 9, 10, 11, 12, 13, or 14 days after MI. Similarly,
increases in blood pressure (hypertension) result in increased
collagen deposition and reduced protein degradation in cardiac
tissue. (Berk et al., J. Clin. Invest., 117(3): 568-575 (2007)).
Anti-LOX/LOXL2 treatment initiated following diagnosis and/or
establishment of Hypertensive Heart Disease or hypertension can
prevent, reduce, or ameliorate fibrosis associated with
hypertension. Such anti-LOX/LOXL2 treatment is initiated 2, 3, 4,
5, 6, 7, 8, 9, 10, 11, 12, 13 or 14 days after increases in
hypertension or systemic blood pressure are diagnosed or
detected.
[0531] As another example, biomarkers may be used to determine when
an inappropriate level of cross-linking might be occurring: for
example, LOX levels have been shown to correlate with C reactive
protein (CRP), a commonly used biomarker, and treatment could begin
when CRP levels are elevated above appropriate normal levels. More
directly, methods and test kits exist to measure the release of
cross-linked collagen telopeptides in urine or blood. Elevated
levels of these collagen fragments could indicate a transition from
reparative fibrosis to reactive (mal-adaptive) fibrosis. In
addition, measures of cardiac function and output, including those
associated with efficient contraction of the ventricle, can be
made.
[0532] An inhibitor of LOX/LOXL2 can be delivered to a subject
prior to, concurrently, or post a pathological cardiac condition or
disease, such as hypertension, hypertensive heart disease (HHD),
myocardial infarction (MI), atherosclerosis, and restenosis, to
prevent the onset of, to reduce the risk of, or to retreat
pathological fibrosis associated with such a pathological cardiac
condition or disease. For example, an inhibitor of LOX/LOXL2 can be
administered at least 1 hr, 2 hrs, 3 hrs, 5 hrs, or 10 hrs, or 1,
2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, or 14 days after the onset
of such a pathological cardiac condition or disease.
[0533] Additionally, a limited duration of treatment is envisioned.
Treatment should be sustained only long enough to prevent or
attenuate reactive fibrosis to prevent or reduce cardiac
dysfunction. For example, short-lived FAB antibody fragments are
used when shorter durations of treatment are desired.
Alternatively, full-length antibodies that have a longer half-life
in serum can be used, with limited dosing over 1, 2, 3, 4, 5, 6, 7,
8, 9, 10, 11, or 12 weeks, inclusive of all days in-between.
Standard tests of cardiac function can be used to monitor progress
and adjust dosing as necessary, along with assessment of relevant
biomarkers discussed above. Limited duration of treatment adds to
the safety of this approach.
[0534] Fibrosis of the liver is implicated in the pathology of
numerous hepatic diseases. As previously noted, fibrosis occurs as
a complication of haemochromatosis, Wilson's disease, alcoholism,
schistosomiasis, viral hepatitis, bile duct obstruction, exposure
to toxins, and metabolic disorders. Left unchecked, hepatic
fibrosis progresses to cirrhosis (defined by the presence of
encapsulated nodules), liver failure, and death. The chronic
insults to the liver from such sources as parasites and viral
infection (e.g. HBV, HCV, HIV, schistosomiasis) or the long term
stress from alcohol consumption inevitably result in remodeling of
the liver, presumably to encapsulate the damaged area and protect
the remaining liver tissue from damage. (Li and Friedman,
Gastroenterol. Hepatol. 14:618-633, 1999). Liver fibrosis results
in extracellular matrix changes, including 3-10 fold increases in
total collagen content and replacement of the low density basement
membrane with high-density matrix, which impair the metabolic and
synthesis function of hepatocytes, hepatic stellate cells and
endothelial cells. (Girogescu, M., Non-invasive Biochemical Markers
of Liver Fibrosis, J. Gastrointestin. Liver Dis., 15(2): 149-159
(2006)). The compounds of the instant invention are thus useful for
the prevention, treatment, and/or amelioration of fibrotic liver
diseases, and such use is contemplated herein by inhibition of
LOX/LOXL2.
[0535] Like liver fibrosis, kidney fibrosis can result from various
diseases and insults to the kidneys. Examples of such diseases and
insults include chronic kidney disease, metabolic syndrome,
diabetes and resultant glomerular nephritis. It has become
recognized that metabolic syndrome is a cluster of abnormalities
including diabetic hallmarks such as insulin resistance as well as
central or visceral obesity and hypertension. In nearly all cases,
dysregulation of glucose results in the stimulation of cytokine
release and upregulation of extracellular matrix deposition.
Additional factors contributing to chronic kidney disease,
diabetes, metabolic syndrome, and glomerular nephritis include
hyperlipidemia, hypertension, and proteinuria, all of which result
in further damage to the kidneys and further stimulate the
extracellular matrix deposition. Thus, regardless of the primary
cause, insults to the kidneys result in kidney fibrosis and the
concomitant loss of kidney function. (Schena, F. and Gesualdo, L.,
Pathogenic Mechanisms of Diabetic Nephropathy, J. Am. Soc.
Nephrol., 16: S30-33 (2005); Whaley-Connell, A., and Sower, J. R.,
Chronic Kidney Disease and the Cardiometabolic Syndrome, J. Clin.
Hypert., 8(8): 546-48 (2006)). The compounds of the instant
invention are thus useful for the prevention, treatment, and/or
amelioration of fibrotic kidney diseases (chronic kidney disease,
diabetic nephropathy, glomerular nephritis, metabolic syndrome),
and such use is contemplated herein.
[0536] Fibrosis of the lung includes many syndromes and diseases.
Exemplary diseases include Idiopathic pulmonary fibrosis (IPF),
Idiopathic Interstitial Pneumonia, and Acute Respiratory Distress
Syndrome (ARDS). The pathogenesis of most lung fibroses, including
the aforementioned diseases are not well understood, however all
are characterized by an influx of inflammatory cells and a
subsequent increase in the synthesis and deposition of
collagen-rich extracellular matrix. (Chua et al., Am J. Respir.
Cell. Mol. Biol., 33:9-13 (2005); Tzortzaki et al., J. Histochem.
& Cytochem., 54(6): 693-700 (2006); Armstrong et al., Am. J.
Respir. Crit. Care Med., 160: 1910-1915 (1999)). Given the
identified role of increased collagen and extracellular matrix
deposition in lung fibroses, the compounds of the present invention
are useful for the prevention, treatment, and/or amelioration of
lung fibroses by the inhibition of LOX/LOXL2.
[0537] Scleroderma is an autoimmune disorder, in which there is an
overproduction of abnormal collagen. This excess collagen
accumulates throughout the body, causing hardening (sclerosis),
scarring (fibrosis), and other damage. The damage may affect the
appearance of the skin, or it may involve only the internal organs.
The symptoms and severity of scleroderma vary from person to
person. Given the identified role of increased collagen in
scleroderma, the compounds of the present invention are useful for
the prevention, treatment, and/or amelioration of scleroderma by
the inhibition of LOX/LOXL2.
[0538] Abnormal angiogenesis that can be treated or prevented by
using this invention include those abnormal angiogenesis
accompanying rheumatoid arthritis, ischemic-reperfusion related
brain edema and injury, cortical ischemia, ovarian hyperplasia and
hypervascularity, (polycystic ovary syndrome), endometriosis,
psoriasis, diabetic retinopaphy, and other ocular angiogenic
diseases such as retinopathy of prematurity (retrolental
fibroplastic), muscular degeneration, corneal graft rejection,
neuroscular glaucoma and Oster Webber syndrome.
[0539] Diseases associated with abnormal angiogenesis require or
induce vascular growth. For example, corneal angiogenesis involves
three phases: a pre-vascular latent period, active
neovascularization, and vascular maturation and regression. The
identity and mechanism of various angiogenic factors, including
elements of the inflammatory response, such as leukocytes,
platelets, cytokines, and eicosanoids, or unidentified plasma
constituents have yet to be revealed.
[0540] Anti-LOX antibodies and anti-LOXL2 antibodies described
herein can be used for treating diseases associated with undesired
or abnormal angiogenesis. The method comprises administering to a
patient suffering from undesired or abnormal angiogenesis a
LOX/LOXL inhibitor in combination with anti-neoplastic agent or
anti-angiogenic agent that is not said LOX/LOXL inhibitor. The
particular dosage of these agents required to inhibit (partially or
completely) angiogenesis and/or angiogenic diseases can depend on
the severity of the condition, the route of administration, and
related factors that can be decided by the attending physician.
Generally, accepted and effective daily doses are the amount
sufficient to effectively inhibit angiogenesis and/or angiogenic
diseases.
[0541] According to this embodiment, the pharmaceutical
formulations of the present invention can be used to treat a
variety of diseases associated with undesirable angiogenesis such
as retinal/choroidal neuvascularization and corneal
neovascularization. Examples of retinal/choroidal
neuvascularization include, but are not limited to, Bests diseases,
myopia, optic pits, Stargarts diseases, Pagets disease, vein
occlusion, artery occlusion, sickle cell anemia, sarcoid, syphilis,
pseudoxanthoma elasticum carotid abostructive diseases, chronic
uveitis/vitritis, mycobacterial infections, Lyme's disease,
systemic lupus erythematosis, retinopathy of prematurity, Eales
disease, diabetic retinopathy, macular degeneration, Bechets
diseases, infections causing a retinitis or chroiditis, presumed
ocular histoplasmosis, pars planitis, chronic retinal detachment,
hyperviscosity syndromes, toxoplasmosis, trauma and post-laser
complications, diseases associated with rubesis (neovascularization
of the angle) and diseases caused by the abnormal proliferation of
fibrovascular or fibrous tissue including all forms of
proliferative vitreoretinopathy. Examples of corneal
neuvascularization include, but are not limited to, epidemic
keratoconjunctivitis, Vitamin A deficiency, contact lens overwear,
atopic keratitis, superior limbic keratitis, pterygium keratitis
sicca, sjogrens, acne rosacea, phylectenulosis, diabetic
retinopathy, retinopathy of prematurity, corneal graft rejection,
Mooren ulcer, Terrien's marginal degeneration, marginal
keratolysis, polyarteritis, Wegener sarcoidosis, Scleritis,
periphigoid radial keratotomy, neovascular glaucoma and retrolental
fibroplasia, syphilis, Mycobacteria infections, lipid degeneration,
chemical burns, bacterial ulcers, fungal ulcers, Herpes simplex
infections, Herpes zoster infections, protozoan infections and
Kaposi sarcoma.
[0542] In yet another embodiment, the pharmaceutical formulations
of the present invention can be used for treating chronic
inflammatory diseases associated with abnormal angiogenesis. The
method comprises administering to a patient suffering from a
chronic inflammatory disease associated with abnormal angiogenesis
a LOX/LOXL2 inhibitor in combination with anti-neoplastic agent or
anti-angiogenic agent that is not said LOX/LOXL2 inhibitor. The
chronic inflammation depends on continuous formation of capillary
sprouts to maintain an influx of inflammatory cells. The influx and
presence of the inflammatory cells produce granulomas and thus,
maintains the chronic inflammatory state. Inhibition of
angiogenesis using the compounds described herein can prevent the
formation of the granulosmas, thereby alleviating the disease.
Examples of chronic inflammatory disease include, but are not
limited to, inflammatory bowel diseases such as Crohn's disease and
ulcerative colitis, psoriasis, sarcoidois, and rheumatoid
arthritis.
[0543] Inflammatory bowel diseases such as Crohn's disease and
ulcerative colitis are characterized by chronic inflammation and
angiogenesis at various sites in the gastrointestinal tract. For
example, Crohn's disease occurs as a chronic transmural
inflammatory disease that most commonly affects the distal ileum
and colon but may also occur in any part of the gastrointestinal
tract from the mouth to the anus and perianal area. Patients with
Crohn's disease generally have chronic diarrhea associated with
abdominal pain, fever, anorexia, weight loss and abdominal
swelling. Ulcerative colitis is also a chronic, nonspecific,
inflammatory and ulcerative disease arising in the colonic mucosa
and is characterized by the presence of bloody diarrhea. These
inflammatory bowel diseases are generally caused by chronic
granulomatous inflammation throughout the gastrointestinal tract,
involving new capillary sprouts surrounded by a cylinder of
inflammatory cells. Inhibition of angiogenesis by the
pharmaceutical formulations of the present invention should inhibit
the formation of the sprouts and prevent the formation of
granulomas. The inflammatory bowel diseases also exhibit extra
intestinal manifestations, such as skin lesions. Such lesions are
characterized by inflammation and angiogenesis and can occur at
many sites other the gastrointestinal tract. Inhibition of
angiogenesis by the pharmaceutical formulations of the present
invention should reduce the influx of inflammatory cells and
prevent the lesion formation. Therefore, provided herein is a
method of treating an inflammatory bowel disease, comprising
administering to a subject in need thereof an effective amount of
an anti-LOX antibody or an anti-LOXL2 antibody; and optionally, a
pharmaceutically acceptable carrier or excipient.
[0544] Sarcoidois, another chronic inflammatory disease, is
characterized as a multisystem granulomatous disorder. The
granulomas of this disease can form anywhere in the body and, thus,
the symptoms depend on the site of the granulomas and whether the
disease is active. The granulomas are created by the angiogenic
capillary sprouts providing a constant supply of inflammatory
cells. By using the pharmaceutical formulations of the present
invention to inhibit angiogenesis, such granulomas formation can be
inhibited. Psoriasis, also a chronic and recurrent inflammatory
disease, is characterized by papules and plaques of various sizes.
Treatment using the pharmaceutical formulations of the present
invention should prevent the formation of new blood vessels
necessary to maintain the characteristic lesions and provide the
patient relief from the symptoms. Therefore, provided herein is a
method of prevent the formation of new blood vessels necessary to
maintain the characteristic lesions and provide the patient relief
from the symptoms, comprising administering to a subject in need
thereof an effective amount of an anti-LOX antibody or an
anti-LOXL2 antibody; and optionally, a pharmaceutically acceptable
carrier or excipient.
[0545] Rheumatoid arthritis (RA) is also a chronic inflammatory
disease characterized by non-specific inflammation of the
peripheral joints. It is believed that the blood vessels in the
synovial lining of the joints undergo angiogenesis. In addition to
forming new vascular networks, the endothelial cells release
factors and reactive oxygen species that lead to pannus growth and
cartilage destruction. The factors involved in angiogenesis can
actively contribute to, and help maintain, the chronically inflamed
state of rheumatoid arthritis. Treatment using the pharmaceutical
formulations of the present invention alone or in conjunction with
other anti-RA agents may prevent the formation of new blood vessels
necessary to maintain the chronic inflammation and provide the RA
patient relief from the symptoms. Other anti-RA agents are
conventional and known in the art. Therefore, provided herein is a
method of preventing or treating RA, comprising administering to a
subject in need thereof an effective amount of an anti-LOX antibody
or an anti-LOXL2 antibody; and optionally, one or more other
anti-RA agents.
[0546] In addition to the use of the anti-LOX antibodies or
anti-LOXL2 antibodies alone in the treatment of the indications
described above, combination therapy is also contemplated herein.
The methods provided herein can further include administering an
anti-cancer agent or treatment to the patient.
[0547] Provided herein is a method of treating any of the
indications described above by administering an anti-LOX antibody
and an anti-LOXL2 antibody.
[0548] In one aspect, this invention features methods for
inhibiting the invasiveness and metastasis of tumor cells, by
contacting the cells with at least one cytotoxic agent and at least
one anti-LOX antibody or anti-LOX2 antibody. In general, the method
includes a step of contacting metastatic tumor cells with an amount
of at least one cytotoxic agent and at least one anti-LOX antibody
or anti-LOX2 antibody, which, in combination, is effective to
reduce or inhibit the invasiveness or metastatic potential of the
cell. Alternatively, according to the present invention, an
anti-LOX antibody or an anti-LOXL2 antibody can be combined with a
chemotherapeutic agent to sensitize tumor cells (e.g., transition
from the EMT state to the MET state) to killed by the
chemotherapeutic agent, thus not only preventing or inhibiting
tumor invasion and metastasis but also inhibiting primary tumor
growth.
[0549] Any suitable anticancer agent may also be employed in the
present methods.
[0550] As used herein the term "chemotherapeutic agent" or
"chemotherapeutic" (or "chemotherapy," in the case of treatment
with a chemotherapeutic agent) is meant to encompass any
non-proteinaceous (i.e., non-peptidic) chemical compound useful in
the treatment of cancer. Examples of chemotherapeutic agents
include alkylating agents such as thiotepa and cyclophosphamide
(CYTOXAN.TM.); alkyl sulfonates such as busulfan, improsulfan and
piposulfan; aziridines such as benzodopa, carboquone, meturedopa,
and uredopa; ethylenimines and methylamelamines including
altretamine, triethylenemelamine, triethylenephosphoramide,
triethylenethiophosphoramide and trimethylolomelamine; acetogenins
(especially bullatacin and bullatacinone); a camptothecin
(including synthetic analogue topotecan); bryostatin; callystatin;
CC-1065 (including its adozelesin, carzelesin and bizelesin
synthetic analogues); cryptophycins (articularly cryptophycin 1 and
cryptophycin 8); dolastatin; duocarmycin (including the synthetic
analogues, KW-2189 and CBI-TMI); eleutherobin; pancratistatin; a
sarcodictyin; spongistatin; nitrogen mustards such as chlorambucil,
chlornaphazine, cholophosphamide, estramustine, ifosfamide,
mechlorethamine, mechlorethamine oxide hydrochloride, melphalan,
novembichin, phenesterine, prednimustine, trofosfamide, uracil
mustard; nitrosoureas such as carmustine, chlorozotocin,
foremustine, lomustine, nimustine, ranimustine; antibiotics such as

anti-androgens such as flutamide, nilutamide, bicalutamide,

[0551] In one non-limiting example, this invention includes methods
for synergistically inhibiting the invasiveness and metastasis of
tumor cells, by contacting the cells with at least cisplatin and at
least one anti-LOX antibody (see FIG. 18). One practicing methods
described herein would understand that an anti-LOX2 antibody could
be used in such methods.
[0552] In one embodiment, the anti-neoplastic agent in combination
with the LOX/LOXL modulator is a tyrosine kinase inhibitor. For
example, ZD1839 (Iressa.TM. of AstraZeneca K.K.) shows a
competitive effect for ATP in ATP binding site of EGFR (epidermal
growth factor receptor) tyrosine kinase, and inhibits tyrosine
kinase activity by inhibiting autophosphorylation of tyrosine
kinase. As a result, the anticancer effect is expressed by blocking
an EGFR-equipping signal transduction (ligands such as epidermal
growth factor (EGF) are bound to the extracellular domain of EGFR,
followed by activation of EGFR tyrosine kinase in the intracellular
domain, causing not only autophosphorylation of EGFR but also
phosphorylation of various intracellular target proteins, then
transducing a proliferation signal from the cell surface to
nucleus, then transducing the proliferation signals from the cancer
cell surface to nucleus, and resulting in proliferation,
infiltration, metastasis, angiogenesis of cancer cells), in
association with proliferation, infiltration, differentiation and
metastasis. IMC-C225 or cetuximab (Erbitux.TM.) which is an
EGFR-targeting monoclonal antibody) recognizes the receptor part of
EGFR on a cell membrane surface and inhibits the
autophosphorylation of EGFR thereby inhibiting the tyrosine kinase
activity. Herceptin is a monoclonal antibody against Her2/Neu which
is homologous to EGFR, and imatinib mesylate (GLEEVEC.TM., formerly
STI-571) can inhibit both tyrosine kinase activities of BCR-Abl and
c-kit (non-patent document No. 2). Sorafenib (Nexavar.TM.) is a
small molecular inhibitor of Raf kinase, PDGF (platelet-derived
growth factor), VEGF receptor 2 & 3 kinases and c-Kit.
[0553] As used herein, monoclonal antibodies against tumor antigens
are antibodies elicited against antigens expressed by tumors and
leukemic cells, preferably tumor-specific antigens. The monoclonal
antibody also includes fully human and humanized antibody.
[0554] Other examples of therapeutic antibodies for cancer therapy
include Trastuzumab (HERCEPTIN.TM.; Overexpression of HER2 protein
is associated with more aggressive disease and poorer prognosis in
the clinic); Rituximab (RITUXAN.TM.) that is raised against CD20 on
lymphoma cells and selectively deplete normal and maligant CD20+
pre-B and mature B cells; Alemtuzumab (CAMPATH.TM.), a monoclonal
antibody that specifically targets CD52 antigen that is found on B
and T lymphocytes and used for the treatment of chronic lymphocytic
leukemia (CLL) and lymphoma; and Gemtuzumab zogamicin
(MYLOTARG.TM.), an antibody conjugate that combines a specific
antibody against CD33 with a chemotherapeutic drug (zogamicin) and
is indicated for the treatment of relapsed adult acute myelocytic
leukemia.
[0555] In another embodiment, anti-angiogenic agent is combined
with a LOX/LOXL inhibitor to treat cancer and other diseases
associated with abnormal or undesirable angiogenesis. Examples of
anti-angiogenic agents include, but are not limited to, retinoid
acid and derivatives thereof, 2-methoxyestradiol, ANGIOSTATIN.TM.,
ENDOSTATIN.TM., suramin, squalamine, tissue inhibitor of
metalloproteinase-I, tissue inhibitor of metalloproteinase-2,
plasminogen activator inhibitor-1, plasminogen activator
inhibitor-2, cartilage-derived inhibitor, paclitaxel, platelet
factor 4, protamine sulphate (clupeine), sulphated chitin
derivatives (prepared from queen crab shells), sulphated

Example 1
Methods of Generating Murine Monoclonal Anti-LOX and Anti-LOXL2
Antibodies
[0559] Mice (BALB/c (00467)) were injected subcutaneously (s.c.), 5
times at 2-3 week intervals with 0.05 mg antigen (Ag) in an
adjuvant formulation. For peptide Ags, peptides were conjugated to
bovine serum albumin and formulated in Freunds Adjuvant (FA) prior
to immunization. For protein Ags, the protein was formulated in
Alhydrogel-Muramyl Dipeptide (ALD/MDP) adjuvant.
[0560] Mice were injected with Ag formulated in PBS, each day for 3
days via a combination of s.c., intraperitoneally (i.p.) and
intravenous (i.v.) routes, 0.05 to 0.1 mg/route.
[0561] Cells from the spleen and lymph nodes of the mice were
isolated and fused with P3X63-Ag8.653 myeloma cells using 50%
polyethylene glycol.
[0562] Cells were cultured and a hybridoma library of HAT-selected
cells was isolated essentially as described in Kenney, et al.
("Production of monoclonal antibodies using a secretion capture
report web." Biotechnology 13:787-790, 1995).
[0563] The hybridoma library was cloned using a fluorescent
activated cell sorter with automatic cell deposition unit.
[0564] Single viable cells were sorted into 96-well plates based
upon the analysis criteria of forward-scatter, side-scatter and
propidium iodide fluorescence as described by Kenney et al.
[0565] Sera and supernatants were screened by enzyme linked
immunosorbant assay (ELISA) using Ag-coated microtiter plate wells,
which were then incubated with mouse plasma or hybridoma
supernatant, followed by goat mouse IgG (Fc-specific) antibody-HRP
conjugate, followed by TMB substrate solution and stop reagent.
[0566] The plate wells were washed to remove unbound antibody or
antigen between all incubations and results determined.
[0567] VH and VL amino acid sequences of an anti-LOXL2 murine
monoclonal antibody identified using the described methods are
provided in FIG. 6A and FIG. 6B, respectively. For each variable
region, signal peptides are shown in italics, CDRs are underlined
and the beginning of the constant framework is shown in bold
font.
[0568] A VH amino acid sequence of an anti-LOX murine monoclonal
antibody identified using the described methods is provided in FIG.
7A. Two VL amino acid sequences of anti-LOX murine monoclonal
antibodies identified using the described methods are provided in
FIGS. 7B and 7C. For each variable region, signal peptides are
shown in italics, CDRs are underlined.
Example 2
[0569] Anti-LOXL2 antibodies were screened using a protein screen B
update to assess enzymatic activity of LOXL2.
[0570] Antibody candidates were initially chosen based on ELISA
point tests. ELISA on multiple antigens was performed by Antibody
Solutions and antibodies showing strong ELISA signal in the antigen
of interest were selected for further characterization in enzymatic
assays. LOXL2 produces hydrogen peroxide when the substrate
1,5-diaminopentane is deaminated and the enzyme regenerated.
[0571] Antibodies were assessed for their ability to inhibit
enzymatic activity using a biochemical assay that couples the
production of peroxide (liberated by LOXL2) to HRP and measuring
the conversion of amplex red to a fluorescent product. Antibody
hybridoma supernatant (10 .mu.L) was added to 40 .mu.L enzyme
mixture (62.5 mM sodium borate pH 8.0, 5 units/mL HRP, 125 nM
LOXL2, 10 ppm antifoam) and incubated at room temperature for 1
hour in a 96 well full area black plate. Enzymatic reaction was
started with the addition of 50 .mu.L of substrate solution (50 mM
sodium borate, 100 .mu.M amplex red reagent, 20 mM
1,5-diaminopentane (DAP), 10 ppm antifoam) and read in a Molecular
Devices M5 plate reader at 37.degree. C. The plate reader was
configured to read fluorescence (ex=544 nm, em=590 nm) in kinetics
mode for 1 hour. Data was recorded as the slope of the fluorescence
response to time. These slopes were compared to a control in which
hydridoma media was added to the enzyme mixture. Slopes less than
that of control were considered inhibitors.
[0572] Antibodies M1 (asc), M4, M11, M1, M13, M22, M16, M19, M20,
M20 (asc) and M25 test antibodies were tested against BAPN (a
competitive inhibitor of LOXL2) as a positive control and LOXL2 as
a negative control (see FIG. 8).
[0573] One anti-LOXL2 antibody was designated AB0023. Anti-LOXL2
antibodies repeated inhibitory activity observed in 10 ml
preparation materials in the enzymatic assay. Inhibition was also
repeated in cell-based assays (see below). Sequence analysis
confirmed that the amino acid sequences of M01, M16, M19 and M20
are identical.
Example 3
Anti-LOXL2 Antibody AB0023 and Enzymatic Activity
[0574] Enzymatic Activity of anti-LOXL2 antibodies can be assessed
and IC50s determined.
[0575] M1, M1 (asc), M20 and M20 (asc) were assessed in the
presence of 25 nM LOXL2 and 15 mM 1.5 DAP over increasing
concentrations of antibody.
IC50 Determinations
[0576] Dose responses on selected antibodies were carried out
against LOXL2 using the coupled enzymatic assay described above. A
dilution series of antibody was created in PBST (0.01% tween-20)
and 10 .mu.L of this was added to 40 .mu.L of enzyme mixture (62.5
mM sodium borate pH 8.0, 5 units/mL HRP, 125 nM LOXL2, 10 ppm
antifoam) and incubated at room temperature for 1 hour in a 96 well
full area black plate. Enzymatic reaction was started with the
addition of 50 .mu.L of substrate solution (50 mM sodium borate,
100 .mu.M amplex red reagent, 20 mM 1,5-diaminopentane, 10 ppm
antifoam) and read in an M5 plate reader using conditions described
above. The slopes of the fluorescence response as a function of
time were plotted against antibody concentration and the data was
fit to a four parameter fit using GraFit. The midpoint of this plot
is the apparent IC50 and is the concentration at which fifty
percent of the total response is inhibited.
[0577] Ab0023 was found to be a partial inhibitor of LOXL2
enzymatic activity with an apparent IC50 of approximately 30 nM
(see FIG. 9).
[0578] Based upon the use of a partial inhibitor in clinic for
therapeutic treatment (i.e., Nevirapine--an approved HIV-1 drug
described by Spence et al. (1995) Science 267), a partial inhibitor
of LOXL2 can also be used in therapeutic applications.
Example 4
Anti-LOXL2 Antibody AB0023 is a Non-Competitive Inhibitor
[0579] The activity of anti-LOXL2 antibody AB0023 was assessed over
increasing concentrations of 1.5 DAP and over increasing
concentrations of antibody (1 .mu.M, 0.005 .mu.M, 0.050 .mu.M, and
0.300 .mu.M).
Mode of Inhibition
[0580] Mode of inhibition of antibodies against LOXL2 was conducted
using the model described below. In these experiments, the
dependence of the steady state rate on the concentration of
1,5-diaminopentane was monitored under increasing concentrations of
antibody. The purpose was to assess whether the K.sub.m for
substrate, k.sub.eat or both change in the presence of antibody.
Collected data was analyzed globally with Grafit using the model
shown in figure below. E represents enzyme, S represents substrate,
A represents antibody, and P represents product. Parameter .alpha.
describes the effect of the compound on substrate affinity. An
.alpha. value equal to one describes a situation in which the
compound binds equally well the free enzyme and the
enzyme-substrate complex (non-competitive inhibition like). Values
less than one describe an interaction in which the compound binds
the enzyme-substrate complex (uncompetitive inhibition like).
Values greater than one correspond to the compound binding the free
enzyme better than the enzyme-substrate complex (competitive
inhibition like). The .beta. value describes the effect of the
modulator on the rate of the enzyme. Inhibitors have values less
than one (for a complete inhibitor (.beta.=0) and activators have
values greater than one. K.sub.A is the dissociation constant of
the compound, K.sub.s is the Michaelis constant for the substrate
and k is the catalytic rate of the enzyme. The steady state rates
were determined from the slope of the fluorescence response as a
function of time as described above (IC50 determination). Data was
plotted as the dependence of steady state rate on the concentration
of substrate (1,5-diaminopentane) at several fixed concentrations
of antibody and analyzed with GraFit.
##STR00001##
[0581] Anti-LOXL2 antibody AB0023 was determined to be a
non-competitive inhibitor based on the following results:
.alpha.=1, K.sub.i=0.067 and .beta.=0.5 (see FIG. 10).
Example 5
Kinetic Measurement of AB0023 Antibody Binding to LOXL2 by Surface
Plasmon Resonance
[0582] Binding affinity and off-rate of AB0023 were assessed via
Surface Plasmon Resonance (SPR).
[0583] Binding affinities were measured using a Bio-Rad ProteOn
instrument thermostated to 25.degree. C. The binding affinities
were determined using two methods, using amine coupling; one in
which the antibody was immobilized and the antigen (LOXL2) was
added, and another in which the antigen (LOXL2) was immobilized and
antibody was added. Antibody or antigen was immobilized on a GLC
chip using at 1:1 ratio of NHS to EDC provided with the ProteOn
immobilization kit. Chip was first activated with NHS/EDC a mixture
and then antigen or antibody at 1 .mu.g/mL in acetate buffer pH 4.5
was flowed over activated surface to couple. This typically yielded
a coupling of about 500 RU's. The activated chip surface was then
capped with the addition of 1M ethanolamine. Coupled chips were
stored at 4.degree. C. and regenerated with 50 mM sodium
hydroxide.
[0584] Dissociation constants were determined by probing the
coupled chip with a dilution series of antibody or antigen in PBST
(0.05% Tween-20). Data was acquired on all six channels available
on the ProteOn using a non-coupled channel as a reference.
Collected data was analyzed using ProteOn manager software from
Bio-Rad.
[0585] AB0023 was found to bind tightly to LOXL2 and release
slowly. Kd was estimated to be 0.1-1.0 nM. Furthermore, AB0023 was
found to have the following characteristics:
k.sub.on=1.68.times.10.sup.6 M.sup.-1s.sup.-1,
k.sub.off=1.17.times.10.sup.-4s.sup.-1, K.sub.D=0.69 nM and
t.sub.1/2=98.7 minutes. See FIG. 11.
Example 6
[0586] Domain mapping was conducted and AB0023 was found to bind to
the SRCR3-4 domain.
Materials and Methods
[0587] All plates were obtained from Corning. Secondary antibody
and Pico substrate were obtained from Pierce. Horse radish
peroxidase (HRP) was obtained from Sigma. All ProteOn reagents were
obtained from Bio-Rad. LOXL2 was obtained from R&D systems.
Antibodies used in this study were produced at Antibody Solution or
via ascites from Aragen Biosciences. All other reagents were of the
highest quality possible.
Binding via ELISA
[0588] Binding of antibody to LOXL2 was determined using a
luminescence based ELISA. White Corning plates were coated with 0.1
.mu.g/mL of LOXL2 or antigen of interest in 50 mM borate buffer (pH
8.0) overnight at 4.degree. C. Plates were washed using BioTek
plate washer and blocked with 5% skim milk in PBST (0.05% tween-20)
for 1 hour at room temperature. Plates were washed with PBST (0.05%
tween-20) and then used immediately or stored at 4.degree. C. in
dessicator for future use. The antibody body to be tested was
serially diluted in PBST (0.01% tween-20) and 100 .mu.L of each
dilution was added per well. Plates were incubated with test
article for 1 hour at room temperature and then washed with PBST
(0.05% Tween-20). Detection antibody (anti-mouse HRP conjugate) was
diluted 16,000 fold in 5% skim milk in PBST (0.05% Tween-20) and
100 .mu.L was applied per well. Plates were incubated for 1 hour
with detection antibody and then washed with PBST (0.05% PBST).
Signal was detected using the SuperSignal ELISA pico
chemiluminescent substrate from Pierce following the manufacturer's
instructions. Luminescence was measure using a Molecular Devices M5
plate reader with an integration time of 500 ms capturing all
wavelengths. Data was background corrected and the dependence of
luminescence signal to antibody concentration was fit using the
Langmuir isotherm equation using the GraFit program. In instances
where the antigen concentration was similar to the dissociation
constant the quadratic equation of tight binding was used. Reported
dissociation values were obtained from the fits to these equations;
were PL represents the signal of the bound complex, B.sub.max is
that maximal binding, K.sub.D is the dissociation constant and L is
the ligand concentration.
[0589] Langmuir Isotherm equation:
[ PL ] = B ma x * [ L ] K D * [ L ] ##EQU00001##
[0590] Tight binding equation:
[ PL ] = B ma x * ( [ P ] T + [ L ] T + K D ) - ( [ P ] T + [ L ] T
+ K D ) 2 - 4 [ P ] T [ L ] T 2 [ P ] T . ##EQU00002##
[0591] AB0023 was tested against MCD-LOXL2, LOXL2 (R&D),
SRCR1-2 and SRCR 1-4. AB0023 was found to bind to the SRCR3-4
domain (see FIG. 12).
Example 7
Inhibition of Migration/Invasion in Collagen I and Collagen IV and
Inhibition of Cell Growth
[0592] Cell based assays were conducted to assess binding of AB0023
to bind substrate (i.e., collagen).
[0593] Briefly, AB0023 was scaled up from various samples prior to
testing.
[0594] Cultrex 96-well collagen I and collagen IV cell invasion
kits (Trevigen, Gaithersburg, Md.) were used for anti-sera/antibody
supernatant screenings. MDA MB 231 cells were serum-deprived 24
hours prior to assay set up. On day of set up, collagen I and
collagen IV coated plates were made at least 4 hours prior to
invasion assay set up (not longer than 8 hours prior). Collagen I
and collagen IV plates were coated according to manufacturer's
instructions. Cells were plated at 20,000 cells per well in 95
.mu.ls serum-free media in the upper chamber of the plate. One
hundred fifty (150) .mu.ls of media containing 10% FBS and 1.times.
L-glutamine was aliquoted into the lower chambers of the plate.
Using a multi-channel pipette, 5 .mu.ls of each anti-sera was
placed in the upper chambers of the plate. The anti-sera and cell
mixture was carefully mixed up and down once with the pipette.
Plates were incubated at 37.degree. C. with 5% CO.sub.2 for 48
hours.
[0595] After 48 hours, the plates were ready to be read. The cell
dissociation solution containing calcein AM was made according to
manufacturer's instructions. The plates were also washed and
disassembled according to manufacturer's instructions. 125 .mu.ls
of cell dissociation solution containing calcein AM was added to
the lower chambered wells and the plates were placed at 37.degree.
C. for 30 minutes. After 30 minutes the sides of the plates were
tapped to loosen the cells, and the plates were placed in incubator
for another 30 minutes at 37.degree. C. The plates were then
disassembled and the lower plate was placed into the plate reader
(SpectraMax M5, Molecular Devices, Sunnyvale, Calif.) with
settings: Flourescence, 485-520 emission, top read, black opaque
plate, sensitivity at 30.
[0596] Consistent inhibition of migration/invasion was observed in
collagen I (FIG. 13) and collagen IV, from supernatents through 10
mL preparation material and scaled up 100 mL preparations and
ascites.
Cell Adhesion Assays
[0597] MDA-MB231 cells were plated in 15 cm.sup.2 plates and grown
in 4.5 g/L glucose containing DMEM (10% FBS and 2 mM L-Glutamine)
so that they were confluent on the day of the assay. The media was
aspirated and the cells were washed 2 times with 10 ml 1 mM EDTA
PBS per plate. Cells were removed from plates by incubating with
another 10 ml 1 mM EDTA PBS for 5 minutes at 37.degree. C. in a
biosafety cabinet and subsequently pipetting the cells off of the
plate in the EDTA PBS solution. Cell concentration was determined
and enough cells for assay (50 k/well plus extra for pipetting)
were spun-down in 15 ml conical tube. Cell pellet was dispersed in
pre-warmed serum-free DMEM to 500K cells/ml and CuCl.sub.2 was
added to 1 .mu.M final concentration. One hundred (100) .mu.l/well
of cell suspension was pipetted into a U-bottom style 96 well
tissue culture plate containing 10 .mu.l of appropriate mAb
dilution. The cell suspension/mAb mixture was left to incubate for
10 minutes at room temperature in the dark. One hundred (100)
.mu.l/well of re-suspended cells/mAb mixture was then transferred
to collagen IV coated 96 well plates (BD Biocoat, BD Biosciences).
Plates were incubated at 37.degree. C. in a biosafety cabinet for 1
hour. Wells were then aspirated and washed gently two times with
200 .mu.l DPBS (Mediatech) to remove cell that had not adhered. One
hundred (100) .mu.l of 10 .mu.M final concentration Calcein-AM (BD
Biosciences) in DPBS was then added to each well to stain the cells
that remained. Plates were incubated at 37.degree. C. in a
biosafety cabinet for 1 hour. Plates were read on a Molecular
Devices M5 plate reader at 494/517 (excitation/emission). Percent
(%) adhesion was calculated by normalizing to PBS or un-related
antibody controls.
[0598] Using this assay, partial inhibition of adhesion was
observed upon exposure of cells to AB0023 antibody.
Cell Growth
[0599] Anti-LOXL2 antibodies inhibited cell growth of four cell
lines: 231 is a breast cancer cell line, BT549 is a breast cancer
cell line, HT1080 is a fibrosacrcoma, and BxPC3 is a prostate
cancer cell line (FIG. 17). Thus, the antibody is effective in
inhibiting growth of cancers of different origins.
Example 8
AB0023 Inhibition of EMT-Like Change
[0600] Epithelial to Mesenchymal changes were assessed using
immunohistochemistry.
[0601] To detect whether a cell is in an EMT or
mesenchymal-to-epithelial transition (MET) state, cells were
stained with antibodies specific to cellular protein markers for
epithelial or mesenchymal states such as E-cadherin, vimentin,
fibronectin, and phalloidin to detect F-actin.
Rhodamine Phalloidin Staining Protocol
[0602] Cells were seeded 24 hours prior to day of staining; cells
were approximately 80% confluent 24 hours later in an 8-chambered
slide. The next day, the media was aspirated and the chambers were
rinsed with 1.times. PBS. Cells were then fixed with 4%
Parafomaldehyde (PFA) for 20 minutes at room temperature and then
rinsed once with 1.times. Phosphate Buffered Saline (PBS). For
permeabilization, the cells were treated with 0.5 Saponin (JT
Baker, Phillipsburg, N.J.) in PBS for 5 minutes at room
temperature. The chambers were carefully rinsed once with 1.times.
PBS, and a 1:100 dilution of rhodamine phalloidin (Invitrogen,
Carlsbad, Calif.) in PBS was added to the cells and incubated for
15 minutes at room temperature. The chambers were rinsed two times
with 1.times. PBS and the slides were mounted with Vectashield
(Vector Laboratories, Burlingame, Calif.).
E-Cadherin Staining Protocol
[0603] Cells were seeded 24 hours prior to day of staining; cells
were approximately 80% confluent the next day in an 8-chambered
slide. The next day, the media was aspirated and the chambers were
rinsed with 1.times. PBS. Cells were then fixed with ice cold
methanol and then incubated for 2 minutes in -20.degree. C. The
cells were rinsed once with 1.times. PBX and 1 .mu.g/ml of
E-cadherin Ab (Calbiochem, Gibbstown, N.J.) was added to the slide
chambers. The slides were then incubated at 37.degree. C. for 1
hour. After carefully rinsing the chambers one time with 1.times.
PBS, the secondary Ab (anti-mouse IgG cy3 conjugated, Jackson
Immuno Research, West Grove, Pa.) was added and incubated at room
temperature for 30-45 minutes. The chambers were rinsed two times
with 1.times. PBS and mounted with Vectashield (Vector
Laboratories, Burlingame, Calif.).
[0604] Conditioned media from HS-578t cells (LOXL2 high) applied to
MCF-7 cells (LOXL2 low/negative). Cells were stained with
rhodamine-phalloidin (F-actin, red) and Dapi (nuclei, blue).
[0605] AB0023 was found to inhibit EMT-like changes induced by
conditioned media from tumor cells that express LOXL2 (data not
shown).

Internalization and Ab Uptake Studies in Hs578t Cells.
[0607] Hs578t cells were cultured in DMEM containing 10% FBS and
1.times. glutamine. The cells were seeded in an 8 chamber glass
slide (BD Falcon, Franklin Lakes, N.J.) and allowed to adhere
overnight. For low confluency, cells were seeded at 30-40,000 cells
per slide. Low confluency was used for detection of Lox in the
cytosol 24 hours later. For high confluency, cells were seeded at
100,000 cells per slide. High confluency was used for detection of
Lox associated with the matrix and collagen approximately 48-72
hours later.
[0608] The following day, 1 .mu.g/ml (final concentration in
regular growth medium) of anti-Lox M64 or anti-Lox12 M20 monoclonal
Ab (mAb) was added to the chambers. For continuous uptake, the mAbs
were incubated with cells at different time points: for example, 3
hours, 8 hours, or 24 hours (overnight). After appropriate amount
of continuous uptake, the media was removed and the chambers were
rinsed with 1.times. PBS. The cells were fixed in 4% PFA
(paraformaldehyde) at room temperature for 20 minutes. After
fixation, the cells were washed with IX PBS at room temperature for
5 minutes and then quenched in 50 mM ammonium chloride at room
temperature for 10 minutes. The cells were washed again with
1.times. PBS at room temperature for 5 minutes.
[0609] The cells were permeabilized by adding saponin buffer (0.5%
Saponin/1% BSA in PBS) at room temperature for 20 minutes. The
secondary detection Ab (Alexa Fluor 488 donkey anti-mouse IgG,
Invitrogen, Carlsbad, Calif.) was added at room temperature in
saponin buffer and the cells were incubated for 30-45 minutes. The
cells were then washed 3.times. in saponin buffer. The slides were
mounted with vectashield (Vector Laboratories, Burlingame,
Calif.).
[0610] For detection of collagen detection, cells were incubated
with anti-collagen antibody (1:50, Calbiochem anti- collagen type I
Rabbit polyclonal, Gibbstown, N.J.), one hour prior to fixing the
cells with 4% PFA. Secondary Ab for collagen used is donkey
anti-rabbit Cy3 (ImmunoJackson Labs, West Grove, Pa.).
[0611] Analysis by immunoblotting and immunofluorescence (data not
shown) indicated that LOXL2 was predominantly intracellular at low
density but was secreted at high cell density (confluent cells).
LOXL2 was detected in the media of confluent cells and also on the
extracellular matrix. Immunofluorescence on live cells indicated
that AB0023 bound LOXL2 associated with the collagen matrix.
Example 10
Anti-LOX Antibody M64 Binds LOX
[0612] The activity of anti-LOX antibody M64 was assessed over
increasing concentrations of 1.5 DAP and over increasing
concentrations of antibody (see FIG. 15).
Materials and Methods
[0613] All plates were obtained from Corning. Secondary antibody
and Pico substrate were from Pierce. Amplex red reagent was from
Invitrogen. Horse radish peroxidase (HRP), 1,5-diaminopentane,
antifoam were from Sigma. All ProteOn reagents were from Bio-Rad.
LOX was produced in house at Arresto Biosciences. Antibodies used
in this study were produced at Antibody Solution or via ascites
(asc) from Aragen Biosciences. All other reagents were of the
highest quality possible.
Binding via ELISA
[0614] Binding of antibody to LOX was determined using a
luminescence based ELISA. White Corning plates were coated with 0.1
ug/mL of LOX or antigen of interest in 50 mM borate buffer (pH 8.0)
overnight at 4.degree. C. Plates were washed using a BioTek plate
washer and blocked with 5% skim milk in PBST (0.05% tween-20) for 1
hour at room temperature. Plates were washed with PBST (0.05%
tween-20) and then used immediately or stored at 4.degree. C. in a
dessicator for future use. The antibody to be tested was serially
diluted in PBST (0.01% tween-20) and 100 uL of each dilution was
added per well. Plates were incubated with test material for 1 hour
at room temperature and then washed with PBST (0.05% tween-20).
Detection antibody (anti-mouse HRP conjugate) was diluted 16000
fold in 5% skim milk in PBST (0.05% tween-20) and 100 uL was
applied per well. Plates were incubated for 1 hour with detection
antibody and then washed with PBST (0.05% PBST). Signal was
detected using the SuperSignal ELISA pico chemiluminescent
substrate from Pierce following the manufacturer's instructions.
Luminescence was measured using a Molecular Devices M5 plate reader
with an integration time of 500 ms capturing all wavelengths. Data
was background corrected and the dependence of luminescence signal
to antibody concentration was fit using the Langmuir isotherm
equation using the GraFit program. In instances where the antigen
concentration was similar to the dissociation constant the
quadratic equation of tight binding was used. Reported dissociation
values were obtained from the fits to these equations; were PL
represents the signal of the bound complex, B.sub.max is that
maximal binding, K.sub.D is the dissociation constant and L is the
ligand concentration.
Langmuir Isotherm Equation
[0615] Langmuir Isotherm equation:
[ PL ] = B ma x * [ L ] K D * [ L ] . ##EQU00003##
[0616] Tight binding equation:
[ PL ] = B ma x * ( [ P ] T + [ L ] T + K D ) - ( [ P ] T + [ L ] T
+ K D ) 2 - 4 [ P ] T [ L ] T 2 [ P ] T . ##EQU00004##
[0617] Anti-LOX antibody M64 was tested in three batches and was
found to have a KD of 6.6 nM, 5.0 nM and 5.7 nM for Batch 3, Batch
4 and Batch 5, respectively (FIG. 15).
Example 11
Kinetic Measurement of M64 Antibody Binding to LOX by Surface
Plasmon Resonance
[0618] Binding affinity of M64 was assessed via Surface Plasmon
Resonance (SPR).
[0619] Binding affinities were measured using a Bio-Rad ProteOn
instrument thermostated to 25.degree. C. The binding affinities
were determined using two methods, using amine coupling; one in
which the antibody was immobilized and the antigen (LOX) was added,
and another in which the antigen (LOX) was immobilized and antibody
was added. Antibody or antigen was immobilized on a GLC chip using
at 1:1 ratio of NHS to EDC provided with the ProteOn immobilization
kit. Chip was first activated with NHS/EDC a mixture and then
antigen or antibody at 1 .mu.g/mL in acetate buffer pH 4.5 was
flowed over activated surface to couple. This typically yielded a
coupling of about 500 RU's. The activated chip surface was then
capped with the addition of 1M ethanolamine. Coupled chips were
stored at 4.degree. C. and regenerated with 50 mM sodium
hydroxide.
[0620] Dissociation constants were determined by probing the
coupled chip with a dilution series of antibody or antigen in PBST
(0.05% tween-20). Data was acquired on all six channels available
on the ProteOn using a non-coupled channel as a reference.
Collected data was analyzed using ProteOn manager software from
Bio-Rad.
[0621] M64 was found to have a K.sub.D of 7 nM (FIG. 16).

[0624] This amino acid sequence contains the amino acid sequence of
V.sub.K variant 2.pro in FIG. 14. The sequence of the nucleic acid
encoding SEQ ID NO:71 is provided in FIG. 19 as SEQ ID NO:72. FIG.
19 further provides the amino acid sequence and encoding nucleic
acid sequence for the signal peptide sequence (indicated by a
single underline), the variable region framework (indicated by a
dashed underline), the CDR regions (indicated by a double
underline); and the constant region framework (provided as
unformatted text). It is understood that, due to the degeneracy of
the genetic code, nucleic acids that encode all or a portion of SEQ
ID NO:71, but that differ in sequence from that shown in FIG. 19
are also contemplated by the present disclosure.
As shown in FIG. 19, the above sequence includes a signal peptide
having the amino acid sequence: MRVPAQLLGLLLLWLPGARC (SEQ ID NO:
73). Thus, the amino acid sequence of the light chain polypeptide
without the signal peptide is:

Example 15
Constructs
[0632] As disclosed above, the present disclosure provides for a
variety of constructs that incorporate at least antigen binding
portions of an anti-LOXL2 antibody, e.g., an anti-human LOXL2
antibody. In one embodiment, the present disclosure provides light
chain polypeptide and heavy chain polypeptides, which may be
provided with or without signal peptides, and which may be provided
in a variety of constructs. The constant region of the heavy chain
polypeptide may be optionally modified to provide for a desired
feature. For example, where the heavy chain constant region
comprises the amino acid sequence of a human heavy chain constant
region polypeptide, it may be modified at the hinge region (e.g.,
by substitution of a naturally occurring serine with a proline). In
one embodiment, a polypeptide is provided that includes, from N- to
C-terminus, a first light chain polypeptide, a first heavy chain
polypeptide, a second light chain polypeptide, and a second heavy
chain polypeptide.
[0633] The amino acid sequences of the light chain polypeptide and
of the heavy chain polypeptide can have the amino acid sequence of
the CDRs of the light chain and heavy chain variable regions
described herein, and further may contain the amino acid sequences
of any of the light chain variable regions, light chain constant
regions, heavy chain variable regions, and/or heavy chain constant
regions as disclosed herein. In one example, the light chain
variable region comprises the CDRs of A130023 as set out in FIG.
14. In one example, the heavy chain variable region comprises the
CDRs of AB0023 as set out in FIG. 14.
[0634] The present disclosure also provides nucleic acid
constructs, such as expression constructs, and recombinant host
cells containing such constructs. For example, a nucleic acid
comprising a sequence encoding a heavy chain polypeptides disclosed
herein (or an antigen binding portion thereof, e.g., SEQ ID NO:79,
or antigen binding portion thereof) can be provided in an
expression construct where the DNA encoding the heavy chain
polypeptide is positioned 3' of a promoter that is capable of
facilitating expression of the heavy chain polypeptide. In another
example, a nucleic acid comprising a sequence encoding a light
chain polypeptide disclosed herein (or an antigen binding portion
thereof, e.g., SEQ ID NO:74, or antigen binding portion thereof)
can be provided in an expression construct where the DNA encoding
the light chain polypeptide is positioned 3' of a promoter that is
capable of facilitating expression of the light chain polypeptide.
In another example, the expression consruct includes a both a heavy
chain polypeptide coding sequence (or antigen binding portion
thereof, e.g., SEQ ID NO:79. or antigen binding portion thereof) or
a light chain polypeptide coding sequence (or antigen binding
portion thereof, e.g., SEQ ID NO:74, or antigen binding portion
thereof). In such constructe the two coding sequences can be under
the control of the same or different promoters. The present
disclosure also provides recombinant host cells containing such
constructs
[0635] In all constructs contemplated by the present disclosure,
the heavy chain and/or light chain coding sequences can include a
sequence encoding a signal peptide. Thus, the present disclosure
provides, for example, an expression construct containing a coding
sequence for a signal peptide and a heavy chain polypeptide
disclosed herein (or an antigen binding portion thereof, e.g., SEQ
ID NO:78, or antigen binding portion thereof), where the coding
sequence is positioned 3' of a promoter that is capable of
facilitating expression of the coding sequence. In another example,
the present disclosure provides an expression construct containing
a coding sequence for a signal peptide and a light chain
polypeptide disclosed herein (or an antigen binding portion
thereof, e.g., SEQ ID NO:71, or antigen binding portion thereof)
where the coding sequence is positioned 3' of a promoter that is
capable of facilitating expression of the coding sequence. In
another example, the expression construct includes both a heavy
chain and a light chain polypeptide coding sequences (or antigen
binding portions thereof), each having a signal peptide. In such
constructs the two coding sequences can be under the control of the
same or different promoters. The present disclosure also provides
recombinant host cells containing such constructs.
[0636] The present disclosure provides a polypeptide composed of
the light chain polypeptide of Example 14 ("kappa") and a modified
heavy chain polypeptide of IgG4 ("IgG4") of Example 14. The amino
acid sequence of the polypeptide is as follows (where the light
chain amino acid sequence is underlined):
