FIELD OF THE INVENTION
[0003] This invention relates generally to antibodies or fragments
thereof which interact with HER family of receptors, e.g., HER3
receptor. In particular, it relates to antibodies or fragments
thereof that recognize a conformational epitope of HER3 receptor
comprising residues from both domains 2 and 4 resulting in
inhibition of both ligand-dependent and ligand-independent signal
transduction; and allow ligand binding (e.g., neuregulin), whilst
preventing ligand-induced activation of signal transduction. These
antibodies or fragments can be used to treat a number of diseases
or disorders characterized by increased levels of HER3 expression
(e.g., esophageal cancer). These antibodies or fragments can be
used to treat a number of diseases or disorders characterized by
the antibodys or fragments ability to decrease tissue weight (e.g.,
prostate or uterine weights) or to induce atrophy of tissue (e.g.,
atrophy of male breast).
BACKGROUND OF THE INVENTION
[0004] The human epidermal growth factor receptor 3 (ErbB3, also
known as HER3) is a receptor protein tyrosine kinase and belongs to
the epidermal growth factor receptor (EGFR) subfamily of receptor
protein tyrosine kinases, which also includes EGFR (HER1, ErbB1),
HER2 (ErbB2, Neu), and HER4 (ErbB4) (Plowman et al., (1990) Proc.
Natl. Acad. Sci. U.S.A. 87:4905-4909; Kraus et al., (1989) Proc.
Natl. Acad. Sci. U.S.A. 86:9193-9197; and Kraus et al., (1993)
Proc. Natl. Acad. Sci. U.S.A. 90:2900-2904). Like the prototypical
epidermal growth factor receptor, the transmembrane receptor HER3
consists of an extracellular ligand-binding domain (ECD), a
dimerization domain within the ECD, a transmembrane domain, an
intracellular protein tyrosine kinase-like domain (TKD) and a
C-terminal phosphorylation domain. Unlike the other HER family
members, the kinase domain of HER3 displays very low intrinsic
kinase activity.
[0005] The ligands neuregulin 1 (NRG) or neuregulin 2 bind to the
extracellular domain of HER3 and activate receptor-mediated
signaling pathway by promoting dimerization with other dimerization
partners such as HER2. Heterodimerization results in activation and
transphosphorylation of HER3's intracellular domain and is a means
not only for signal diversification but also signal amplification.
In addition, HER3 heterodimerization can also occur in the absence
of activating ligands and this is commonly termed
ligand-independent HER3 activation. For example, when HER2 is
expressed at high levels as a result of gene amplification (e.g. in
breast, lung, ovarian or gastric cancer) spontaneous HER2/HER3
dimers can be formed. In this situation the HER2/HER3 is considered
the most active ErbB signaling dimer and is therefore highly
transforming.
[0006] Increased HER3 has been found in several types of cancer
such as breast, lung, gastrointestinal and pancreatic cancers.
Interestingly, a correlation between the expression of HER2/HER3
and the progression from a non-invasive to an invasive stage has
been shown (Alimandi et al., (1995) Oncogene 10:1813-1821; DeFazio
et al., (2000) Cancer 87:487-498; Naidu et al., (1988) Br. J.
Cancer 78:1385-1390). Accordingly, agents that interfere with HER3
mediated signaling are needed.
SUMMARY OF THE INVENTION
[0007] The invention is based on the discovery of antigen binding
proteins (e.g., antibodies or fragments thereof) that bind to a
conformational epitope of HER3 receptor comprising amino acid
residues within domain 2 and domain 4 of HER3. This binding of the
antibodies or fragments thereof with domain 2 and domain 4
stabilizes the HER3 receptor in an inactive or closed conformation
such that HER3 activation is inhibited. Surprisingly, binding of
the antibodies or fragments thereof with this conformational
epitope blocks both ligand-dependent (e.g. neuregulin) and
ligand-independent HER3 signaling pathways. Furthermore, antibody
mediated inhibition of ligand induced signaling occurs without
blocking ligand binding (i.e. both ligand and antibody can bind
HER3) presumably because HER3 cannot undergo the conformational
rearrangements required for activation. Also disclosed are methods
for using the antibodies or fragments thereof to treat a number of
diseases or disorders characterized by increased expression of
HER3; and disease or disorders characterized by the antibodies or
fragments ability to decrease tissue weight (e.g., prostate or
uterine weights) or to induce atrophy of tissue (e.g., atrophy of
male breast).

DETAILED DESCRIPTION OF THE INVENTION
Definitions
[0036] In order that the present invention may be more readily
understood, certain terms are first defined. Additional definitions
are set forth throughout the detailed description.
[0037] The phrase "signal transduction" or "signaling activity" as
used herein refers to a biochemical causal relationship generally
initiated by a protein-protein interaction such as binding of a
growth factor to a receptor, resulting in transmission of a signal
from one portion of a cell to another portion of a cell. For HER3,
the transmission involves specific phosphorylation of one or more
tyrosine, serine, or threonine residues on one or more proteins in
the series of reactions causing signal transduction. Penultimate
processes typically include nuclear events, resulting in a change
in gene expression.
[0038] A "HER receptor" is a receptor protein tyrosine kinase which
belongs to the HER receptor family and includes EGFR, HER2, HER3
and HER4 receptors and other members of this family to be
identified in the future. The HER receptor will generally comprise
an extracellular domain, which may bind an HER ligand; a lipophilic
transmembrane domain; a conserved intracellular tyrosine kinase
domain; and a carboxyl-terminal signaling domain harboring several
tyrosine residues which can be phosphorylated. Preferably the HER
receptor is native sequence human HER receptor.
[0039] The terms "HER1," "ErbB1," "epidermal growth factor
receptor" and "EGFR" are used interchangeably herein and refer to
EGFR as disclosed, for example, in Carpenter et al. Ann. Rev.
Biochem. 56:881-914 (1987), including naturally occurring mutant
forms thereof (e.g. a deletion mutant EGFR as in Humphrey et al.,
(1990) PNAS (USA) 87:4207-4211). erbB1 refers to the gene encoding
the EGFR protein product.
[0040] The terms "HER2" and "ErbB2" and are used interchangeably
herein and refer to human HER2 protein described, for example, in
Semba et al., (1985) PNAS (USA) 82:6497-6501 and Yamamoto et al.
(1986) Nature 319:230-234 (Genebank accession number X03363). The
term "erbB2" refers to the gene encoding human ErbB2 and "neu"
refers to the-gene encoding rat p185.sup.neu.
[0041] The terms "HER4" and "ErbB4" herein refer to the receptor
polypeptide as disclosed, for example, in EP Pat Appln No 599,274;
Plowman et al., (1993) Proc. Natl. Acad. Sci. USA, 90:1746-1750;
and Plowman et al., (1993) Nature, 366:473-475, including isoforms
thereof, e.g., as disclosed in WO99/19488, published Apr. 22,
1999.
[0042] The term "HER3" or "HER3 receptor" also known as "ErbB3" as

refers to mammalian her3 gene. The preferred HER3 protein is human
HER3 protein present in the cell membrane of a cell. The human her3
gene is described in U.S. Pat. No. 5,480,968 and Plowman et al.,
(1990) Proc. Natl. Acad. Sci. USA, 87:4905-4909.

[0044] The term "HER ligand" as used herein refers to polypeptides
which bind and activate HER receptors such as HER1, HER2, HER3 and
HER4. Examples of HER ligands include, but are not limited to
neuregulin 1 (NRG), neuregulin 2, neuregulin 3, neuregulin 4,
betacellulin, heparin-binding epidermal growth factor, epiregulin,
epidermal growth factor, amphiregulin, and transforming growth
factor alpha. The term includes biologically active fragments
and/or variants of a naturally occurring polypeptide.
[0045] The term "HER3 ligand" as used herein refers to polypeptides
which bind and activate HER3. Examples of HER3 ligands include, but
are not limited to neuregulin 1 (NRG) and neuregulin 2,
betacellulin, heparin-binding epidermal growth factor, and
epiregulin. The term includes biologically active fragments and/or
variants of a naturally occurring polypeptide.
[0046] The "HER-HER protein complex" is a noncovalently associated
oligomer containing a HER co-receptors in any combination (e.g.,
HER1-HER2, HER1-HER3, HER1-HER4, HER2-HER3, HER3-HER4, and the
like). This complex can form when a cell expressing both of these
receptors is exposed to a HER ligand e.g., NRG, or when a HER
receptor is active or overexpressed.
[0047] The "HER2-HER3 protein complex" is a noncovalently
associated oligomer containing HER2 receptor and the HER3 receptor.
This complex can form when a cell expressing both of these
receptors is exposed to a HER3 ligand e.g., NRG or when HER2 is
active/overexpressed
[0048] The phrase "HER3 activity" or "HER3 activation" as used
herein refers to an increase in oligomerization (e.g. an increase
in HER3 containing complexes), HER3 phosphorylation, conformational
rearrangements (for example those induced by ligands), and HER3
mediated downstream signaling.
[0049] The term "stabilization" or "stabilized" used in the context
of HER3 refers to an antibody or fragment thereof that directly
maintains (locks, tethers, holds, preferentially binds, favors) the
inactive state or conformation of HER3 without blocking ligand
binding to HER3, such that ligand binding is no longer able to
activate HER3. Assays described in the Examples can be used to
measure ligand binding to a stabilized HER3 receptor, e.g., Biacore
assay.
[0050] The term "ligand-dependent signaling" as used herein refers
to the activation of HER (e.g., HER3) via ligand. HER3 activation
is evidenced by increased oligomerization (e.g. heterodimerization)
and/or HER3 phosphorylation such that downstream signaling pathways
(e.g. PI3K) are activated. The antibody or fragment thereof can
statistically significantly reduce the amount of phosphorylated
HER3 in a stimulated cell exposed to the antigen binding protein
(e.g., an antibody) relative to an untreated (control) cell, as
measured using the assays described in the Examples. The cell which
expresses HER3 can be a naturally occurring cell line (e.g. MCF7)
or can be recombinantly produced by introducing nucleic acids
encoding HER3 protein into a host cell. Cell stimulation can occur
either via the exogenous addition of an activating HER3 ligand or
by the endogenous expression of an activating ligand.
[0051] The antibody or fragment thereof which "reduces
neuregulin-induced HER3 activation in a cell" is one which
statistically significantly reduces HER3 tyrosine phosphorylation
relative to an untreated (control) cell, as measured using the
assays described in the Examples. This can be determined based on
HER3 phosphotyrosine levels following exposure of HER3 to NRG and
the antibody of interest. The cell which expresses HER3 protein can
be a naturally occurring cell or cell line (e.g. MCF7) or can be
recombinantly produced.
[0052] The term "ligand-independent signaling" as used herein
refers to cellular HER3 activity (e.g phosphorylation) in the
absence of a requirement for ligand binding. For example,
ligand-independent HER3 activation can be a result of HER2
overexpression or activating mutations in HER3 heterodimer partners
such as EGFR and HER2. The antibody or fragment thereof can
statistically significantly reduce the amount of phosphorylated
HER3 in a cell exposed to the antigen binding protein (e.g., an
antibody) relative to an untreated (control) cell. The cell which
expresses HER3 can be a naturally occurring cell line (e.g.
SK-Br-3) or can be recombinantly produced by introducing nucleic
acids encoding HER3 protein into a host cell.
[0053] The term "blocks" as used herein refers to stopping or
preventing an interaction or a process, e.g., stopping
ligand-dependent or ligand-independent signaling.
[0054] The term "recognize" as used herein refers to an antibody or
fragment thereof that finds and interacts (e.g., binds) with its
conformational epitope.
[0055] The phrase "concurrently binds" as used herein refers to a
HER ligand that can bind to a ligand binding site on the HER
receptor along with the HER antibody. This means that both the
antibody and antibody can bind to the HER receptor together. For
the sake of illustration only, the HER3 ligand NRG, can bind to the
HER3 receptor along with the HER3 antibody. Assay to measure
concurrent binding of the ligand and antibody are described in the
Examples section (e.g., Biacore).
[0056] The term "fails" as used herein refers to an antibody or
fragment thereof that does not do a particular event. For example,
an antibody or fragment thereof that "fails to activate signal
transduction" is one that does not trigger signal transduction; an
antibody or fragment thereof that "fails to induce a conformational
change" is one that does not cause a structural alteration in the
HER receptor; an antibody or fragment thereof that stabilizes the
HER receptor in an inactive state such that the HER receptor "fails
to dimerize" is one that does not form protein-protein
complexes.
[0057] The term "antibody" as used herein refers to whole
antibodies that interact with (e.g., by binding, steric hindrance,
stabilizing/destabilizing, spatial distribution) an HER3 epitope
and inhibit signal transduction. A naturally occurring "antibody"
is a glycoprotein comprising at least two heavy (H) chains and two
light (L) chains inter-connected by disulfide bonds. Each heavy
chain is comprised of a heavy chain variable region (abbreviated
herein as VH) and a heavy chain constant region. The heavy chain
constant region is comprised of three domains, CH1, CH2 and CH3.
Each light chain is comprised of a light chain variable region
(abbreviated herein as VL) and a light chain constant region. The
light chain constant region is comprised of one domain, CL. The VH
and V.sub.L regions can be further subdivided into regions of
hypervariability, termed complementarity determining regions (CDR),
interspersed with regions that are more conserved, termed framework
regions (FR). Each VH and VL is composed of three CDRs and four FRs
arranged from amino-terminus to carboxy-terminus in the following
order: FR1, CDR1, FR2, CDR2, FR3, CDR3, FR4. The variable regions
of the heavy and light chains contain a binding domain that
interacts with an antigen. The constant regions of the antibodies
may mediate the binding of the immunoglobulin to host tissues or
factors, including various cells of the immune system (e.g.,
effector cells) and the first component (C1q) of the classical
complement system. The term "antibody" includes for example,
monoclonal antibodies, human antibodies, humanized antibodies,
camelised antibodies, chimeric antibodies, single-chain Fvs (scFv),
disulfide-linked Fvs (sdFv), Fab fragments, F (ab') fragments, and
anti-idiotypic (anti-Id) antibodies (including, e.g., anti-Id
antibodies to antibodies of the invention), and epitope-binding
fragments of any of the above. The antibodies can be of any isotype
(e.g., IgG, IgE, IgM, IgD, IgA and IgY), class (e.g., IgG1, IgG2,
IgG3, IgG4, IgA1 and IgA2) or subclass.
[0058] Both the light and heavy chains are divided into regions of
structural and functional homology. The terms "constant" and
"variable" are used functionally. In this regard, it will be
appreciated that the variable domains of both the light (VL) and
heavy (VH) chain portions determine antigen recognition and
specificity. Conversely, the constant domains of the light chain
(CL) and the heavy chain (CH1, CH2 or CH3) confer important
biological properties such as secretion, transplacental mobility,
Fc receptor binding, complement binding, and the like. By
convention the numbering of the constant region domains increases
as they become more distal from the antigen binding site or
amino-terminus of the antibody. The N-terminus is a variable region
and at the C-terminus is a constant region; the CH3 and CL domains
actually comprise the carboxy-terminus of the heavy and light
chain, respectively.
[0059] The phrase "antibody fragment", as used herein, refers to
one or more portions of an antibody that retain the ability to
specifically interact with (e.g., by binding, steric hindrance,
stabilizing/destabilizing, spatial distribution) an HER3 epitope
and inhibit signal transduction. Examples of binding fragments
include, but are not limited to, a Fab fragment, a monovalent
fragment consisting of the VL, VH, CL and CH1 domains; a
F(ab).sub.2 fragment, a bivalent fragment comprising two Fab
fragments linked by a disulfide bridge at the hinge region; a Fd
fragment consisting of the VH and CH1 domains; a Fv fragment
consisting of the VL and VH domains of a single arm of an antibody;
a dAb fragment (Ward et al., (1989) Nature 341:544-546), which
consists of a VH domain; and an isolated complementarity
determining region (CDR).
[0060] Furthermore, although the two domains of the Fv fragment, VL
and VH, are coded for by separate genes, they can be joined, using
recombinant methods, by a synthetic linker that enables them to be
made as a single protein chain in which the VL and VH regions pair
to form monovalent molecules (known as single chain Fv (scFv); see
e.g., Bird et al., (1988) Science 242:423-426; and Huston et al.,
(1988) Proc. Natl. Acad. Sci. 85:5879-5883). Such single chain
antibodies are also intended to be encompassed within the term
"antibody fragment". These antibody fragments are obtained using
conventional techniques known to those of skill in the art, and the
fragments are screened for utility in the same manner as are intact
antibodies.
[0061] Antibody fragments can also be incorporated into single
domain antibodies, maxibodies, minibodies, intrabodies, diabodies,
triabodies, tetrabodies, v-NAR and bis-scFv (see, e.g., Hollinger
and Hudson, (2005) Nature Biotechnology 23:1126-1136). Antibody
fragments can be grafted into scaffolds based on polypeptides such
as Fibronectin type III (Fn3) (see U.S. Pat. No. 6,703,199, which
describes fibronectin polypeptide monobodies).
[0062] Antibody fragments can be incorporated into single chain
molecules comprising a pair of tandem Fv segments (VH-CH1-VH-CH1)
which, together with complementary light chain polypeptides, form a
pair of antigen binding regions (Zapata et al., (1995) Protein Eng.
8:1057-1062; and U.S. Pat. No. 5,641,870).
[0063] The term "epitope" includes any protein determinant capable
of specific binding to an immunoglobulin or otherwise interacting
with a molecule. Epitopic determinants generally consist of
chemically active surface groupings of molecules such as amino
acids or carbohydrate or sugar side chains and can have specific
three-dimensional structural characteristics, as well as specific
charge characteristics. An epitope may be "linear" or
"conformational."
[0064] The term "linear epitope" refers to an epitope with all of
the points of interaction between the protein and the interacting
molecule (such as an antibody) occur linearly along the primary
amino acid sequence of the protein (continuous). Once a desired
epitope on an antigen is determined, it is possible to generate
antibodies to that epitope, e.g., using the techniques described in
the present invention. Alternatively, during the discovery process,
the generation and characterization of antibodies may elucidate
information about desirable epitopes. From this information, it is
then possible to competitively screen antibodies for binding to the
same epitope. An approach to achieve this is to conduct
cross-competition studies to find antibodies that competitively
bind with one another, e.g., the antibodies compete for binding to
the antigen. A high throughput process for "binning" antibodies
based upon their cross-competition is described in International
Patent Application No. WO 2003/48731. As will be appreciated by one
of skill in the art, practically anything to which an antibody can
specifically bind could be an epitope. An epitope can comprises
those residues to which the antibody binds.
[0065] The term "conformational epitope" refers to an epitope in
which discontinuous amino acids that come together in three
dimensional conformation. In a conformational epitope, the points
of interaction occur across amino acid residues on the protein that
are separated from one another. In one embodiment, the epitope is
that described in Examples of this specification. In one
embodiment, the conformational epitope is defined by (i) HER3 amino
acid residues 265-277 and 315 (of domain 2) and (ii) HER3 amino
acid residues 571, 582-584, 596-597, 600-602, 609-615 (of domain 4)
of SEQ ID NO: 1, or a subset thereof. As will be appreciated by one
of skill in the art, the space that is occupied by a residue or
side chain that creates the shape of a molecule helps to determine
what an epitope is.
[0066] Generally, antibodies specific for a particular target
antigen will preferentially recognize an epitope on the target
antigen in a complex mixture of proteins and/or macromolecules.
[0067] Regions of a given polypeptide that include an epitope can
be identified using any number of epitope mapping techniques, well
known in the art. See, e.g., Epitope Mapping Protocols in Methods
in Molecular Biology, Vol. 66 (Glenn E. Morris, Ed., 1996) Humana
Press, Totowa, N.J. For example, linear epitopes may be determined
by e.g., concurrently synthesizing large numbers of peptides on
solid supports, the peptides corresponding to portions of the
protein molecule, and reacting the peptides with antibodies while
the peptides are still attached to the supports. Such techniques
are known in the art and described in, e.g., U.S. Pat. No.
4,708,871; Geysen et al., (1984) Proc. Natl. Acad. Sci. USA
8:3998-4002; Geysen et al., (1985) Proc. Natl. Acad. Sci. USA
82:78-182; Geysen et al., (1986) Mol. Immunol. 23:709-715.
Similarly, conformational epitopes are readily identified by
determining spatial conformation of amino acids such as by, e.g.,
hydrogen/deuterium exchange, x-ray crystallography and
two-dimensional nuclear magnetic resonance. See, e.g., Epitope
Mapping Protocols, supra. Antigenic regions of proteins can also be
identified using standard antigenicity and hydropathy plots, such
as those calculated using, e.g., the Omiga version 1.0 software
program available from the Oxford Molecular Group. This computer
program employs the Hopp/Woods method, Hopp et al., (1981) Proc.
Natl. Acad. Sci USA 78:3824-3828; for determining antigenicity
profiles, and the Kyte-Doolittle technique, Kyte et al., (1982) J.
Mol. Biol. 157:105-132; for hydropathy plots.
[0068] The term "paratope" as used herein refers to the general
structure of a binding region that determines binding to an
epitope. This structure influences whether or not and in what
manner the binding region might bind to an epitope. Paratope can
refer to an antigenic site of an antibody that is responsible for
an antibody or fragment thereof, to bind to an antigenic
determinant. Paratope also refers to the idiotope of the antibody,
and the complementary determining region (CDR) region that binds to
the epitope. In one embodiment, the paratope is the region of the
antibody that binds to the conformational epitope comprising (i)
HER3 amino acid residues 265-277 and 315 (of domain 2), and (ii)
HER3 amino acid residues 571, 582-584, 596-597, 600-602, 609-615
(of domain 4) of SEQ ID NO: 1, or a subset thereof. In one
embodiment, the paratope is the region of the antibody that
comprises the CDR sequences. In one embodiment, the paratope
comprises the sequences listed in Table 1. In one embodiment, the
paratope comprises at least one amino acid residue that binds with
HER3 residues: Asn266, Lys267, Leu268, Thr269, Gln271, Glu273,
Pro274, Asn275, Pro276, His277, Asn315, Asp571, Pro583, His584,
Ala596, Lys597 (residues of SEQ ID NO: 1). In one embodiment, the
paratope comprises at least one amino acid residue that binds with
HER3 residues: Tyr265, Lys267, Leu268, Phe270, Gly582, Pro583,
Lys597, Ile600, Lys602, Glu609, Arg611, Pro612, Cys613, His614,
Glu615 (residues of SEQ ID NO: 1). As will be appreciated by one of
skill in the art, the paratope of any antibody, or variant thereof,
can be determined in the manner set forth by the present
application.
[0069] The phrases "monoclonal antibody" or "monoclonal antibody
composition" as used herein refers to polypeptides, including
antibodies, antibody fragments, bispecific antibodies, etc. that
have substantially identical to amino acid sequence or are derived
from the same genetic source. This term also includes preparations
of antibody molecules of single molecular composition. A monoclonal
antibody composition displays a single binding specificity and
affinity for a particular epitope.
[0070] The phrase "human antibody", as used herein, includes
antibodies having variable regions in which both the framework and
CDR regions are derived from sequences of human origin.
[0071] Furthermore, if the antibody contains a constant region, the
constant region also is derived from such human sequences, e.g.,
human germline sequences, or mutated versions of human germline
sequences or antibody containing consensus framework sequences
derived from human framework sequences analysis, for example, as
described in Knappik et al., (2000) J Mol Biol 296:57-86). The
structures and locations of immunoglobulin variable domains, e.g.,
CDRs, may be defined using well known numbering schemes, e.g., the
Kabat numbering scheme, the Chothia numbering scheme, or a
combination of Kabat and Chothia (see, e.g., Sequences of Proteins
of Immunological Interest, U.S. Department of Health and Human
Services (1991), eds. Kabat et al.; Lazikani et al., (1997) J. Mol.
Bio. 273:927-948); Kabat et al., (1991) Sequences of Proteins of
Immunological Interest, 5th edit., NIH Publication no. 91-3242 U.S.
Department of Health and Human Services; Chothia et al., (1987) J.
Mol. Biol. 196:901-917; Chothia et al., (1989) Nature 342:877-883;
and Al-Lazikani et al., (1997) J. Mol. Biol. 273:927-948.
[0072] The human antibodies of the invention may include amino acid
residues not encoded by human sequences (e.g., mutations introduced
by random or site-specific mutagenesis in vitro or by somatic
mutation in vivo, or a conservative substitution to promote
stability or manufacturing).
[0073] The phrase "human monoclonal antibody" as used herein refers
to antibodies displaying a single binding specificity which have
variable regions in which both the framework and CDR regions are
derived from human sequences. In one embodiment, the human
monoclonal antibodies are produced by a hybridoma which includes a
B cell obtained from a transgenic nonhuman animal, e.g., a
transgenic mouse, having a genome comprising a human heavy chain
transgene and a light chain transgene fused to an immortalized
cell.
[0074] The phrase "recombinant human antibody", as used herein,
includes all human antibodies that are prepared, expressed, created
or isolated by recombinant means, such as antibodies isolated from
an animal (e.g., a mouse) that is transgenic or transchromosomal
for human immunoglobulin genes or a hybridoma prepared therefrom,
antibodies isolated from a host cell transformed to express the
human antibody, e.g., from a transfectoma, antibodies isolated from
a recombinant, combinatorial human antibody library, and antibodies
prepared, expressed, created or isolated by any other means that
involve splicing of all or a portion of a human immunoglobulin
gene, sequences to other DNA sequences. Such recombinant human
antibodies have variable regions in which the framework and CDR
regions are derived from human germline immunoglobulin sequences.
In certain embodiments, however, such recombinant human antibodies
can be subjected to in vitro mutagenesis (or, when an animal
transgenic for human Ig sequences is used, in vivo somatic
mutagenesis) and thus the amino acid sequences of the V.sub.H and
V.sub.L regions of the recombinant antibodies are sequences that,
while derived from and related to human germline V.sub.H and
V.sub.L sequences, may not naturally exist within the human
antibody germline repertoire in vivo.
[0075] Specific binding between two entities means a binding with
an equilibrium constant (K.sub.A) (k.sub.on/k.sub.off) of at least
10.sup.2M.sup.-1, at least 5.times.10.sup.2M.sup.-1, at least
10.sup.3M.sup.-1, at least 5.times.10.sup.3M.sup.-1, at least
10.sup.4M.sup.-1 at least 5.times.10.sup.4M.sup.-1, at least

10.sup.8M.sup.-1, at least 5.times.10.sup.8M.sup.-1, at least
10.sup.9M.sup.-1, at least 5.times.10.sup.9M.sup.-1, at least
10.sup.10M.sup.-1, at least 5.times.10.sup.11M.sup.-1, at least
10.sup.11M.sup.-1, at least 5.times.10.sup.11M.sup.-1, at least
10.sup.12M.sup.-1, at least 5.times.10.sup.12M.sup.-1, at least
10.sup.13M.sup.-1, at least 5.times.10.sup.13 M.sup.-1, at least
10.sup.14M.sup.-1 at least 5.times.10.sup.14M.sup.-1, at least
10.sup.15M.sup.-1, or at least 5.times.10.sup.15M.sup.-1.
[0076] The phrase "specifically (or selectively) binds" to an
antibody (e.g., a HER3 binding antibody) refers to a binding
reaction that is determinative of the presence of a cognate antigen
(e.g., a human HER3) in a heterogeneous population of proteins and
other biologics. In addition to the equilibrium constant (K.sub.A)
noted above, an HER3 binding antibody of the invention typically
also has a dissociation rate constant (K.sub.D)
(k.sub.off/k.sub.on) of less than 5.times.10.sup.-2M, less than
10.sup.-2M, less than 5.times.10.sup.-3M, less than 10.sup.-4M,
less than 5.times.10.sup.-4M, less than 10.sup.4M, less than
5.times.10.sup.-5M, less than 10.sup.-5M, less than
5.times.10.sup.-6M, less than 10.sup.-6M, less than
5.times.10.sup.-7M, less than 10.sup.-7M, less than
5.times.10.sup.-8M, less than 10.sup.-8M, less than
5.times.10.sup.-9M, less than 10.sup.-9M, less than
5.times.10.sup.-10M, less than 10.sup.-10 M, less than
5.times.10.sup.-11M, less than 10.sup.-11M, less than
5.times.10.sup.-12M, less than 10.sup.-12M, less than
5.times.10.sup.-13M, less than 10.sup.-13M, less than
5.times.10.sup.-14M, less than 10.sup.-14M, less than
5.times.10.sup.-15M, or less than 10.sup.-15M or lower, and binds
to HER3 with an affinity that is at least two-fold greater than its
affinity for binding to a non-specific antigen (e.g., HSA).
[0077] In one embodiment, the antibody or fragment thereof has
dissociation constant (K.sub.d) of less than 3000 pM, less than
2500 pM, less than 2000 pM, less than 1500 pM, less than 1000 pM,
less than 750 pM, less than 500 pM, less than 250 pM, less than 200
pM, less than 150 pM, less than 100 pM, less than 75 pM, less than
10 pM, less than 1 pM as assessed using a method described herein
or known to one of skill in the art (e.g., a BIAcore assay, ELISA,
FACS, SET) (Biacore International AB, Uppsala, Sweden). The term
"K.sub.assoc" or "K.sub.a", as used herein, refers to the
association rate of a particular antibody-antigen interaction,
whereas the term "K.sub.dis" or "K.sub.d," as used herein, refers
to the dissociation rate of a particular antibody-antigen
interaction. The term "K.sub.D", as used herein, refers to the
dissociation constant, which is obtained from the ratio of K.sub.d
to K.sub.a (i.e. K.sub.d/K.sub.a) and is expressed as a molar
concentration (M). K.sub.D values for antibodies can be determined
using methods well established in the art. A method for determining
the K.sub.D of an antibody is by using surface plasmon resonance,
or using a biosensor system such as a Biacore.RTM. system.
[0078] The term "affinity" as used herein refers to the strength of
interaction between antibody and antigen at single antigenic sites.
Within each antigenic site, the variable region of the antibody
"arm" interacts through weak non-covalent forces with antigen at
numerous sites; the more interactions, the stronger the
affinity.
[0079] The term "avidity" as used herein refers to an informative
measure of the overall stability or strength of the
antibody-antigen complex. It is controlled by three major factors:
antibody epitope affinity; the valence of both the antigen and
antibody; and the structural arrangement of the interacting parts.
Ultimately these factors define the specificity of the antibody,
that is, the likelihood that the particular antibody is binding to
a precise antigen epitope.
[0080] The term "valency" as used herein refers to the number of
potential target binding sites in a polypeptide. Each target
binding site specifically binds one target molecule or specific
site (i.e, epitope) on a target molecule. When a polypeptide
comprises more than one target binding site, each target binding
site may specifically bind the same or different molecules (e.g.,
may bind to different molecules, e.g., different antigens, or
different epitopes on the same molecule).
[0081] The phrase "antagonist antibody" as used herein refers to an
antibody that binds with HER3 and neutralizes the biological
activity of HER3 signaling, e.g., reduces, decreases and/or
inhibits HER3 induced signaling activity, e.g., in a phospho-HER3
or phospho-Akt assay. Examples of assays are described in more
details in the examples below. Accordingly, an antibody that
"inhibits" one or more of these HER3 functional properties (e.g.,
biochemical, immunochemical, cellular, physiological or other
biological activities, or the like) as determined according to
methodologies known to the art and described herein, will be
understood to relate to a statistically significant decrease in the
particular activity relative to that seen in the absence of the
antibody (e.g., or when a control antibody of irrelevant
specificity is present). An antibody that inhibits HER3 activity
effects such a statistically significant decrease by at least 10%
of the measured parameter, by at least 50%, 80% or 90%, and in
certain embodiments an antibody of the invention may inhibit
greater than 95%, 98% or 99% of HER3 functional activity as
evidenced by a reduction in the level of cellular HER3
phosphorylation.
[0082] The phrase "isolated antibody" refers to an antibody that is
substantially free of other antibodies having different antigenic
specificities (e.g., an isolated antibody that specifically binds
HER3 is substantially free of antibodies that specifically bind
antigens other than HER3). An isolated antibody that specifically
binds HER3 may, however, have cross-reactivity to other antigens.
Moreover, an isolated antibody may be substantially free of other
cellular material and/or chemicals.
[0083] The phrase "conservatively modified variant" applies to both
amino acid and nucleic acid sequences. With respect to particular
nucleic acid sequences, conservatively modified variants refers to
those nucleic acids which encode identical or essentially identical
amino acid sequences, or where the nucleic acid does not encode an
amino acid sequence, to essentially identical sequences. Because of
the degeneracy of the genetic code, a large number of functionally
identical nucleic acids encode any given protein. For instance, the
codons GCA, GCC, GCG and GCU all encode the amino acid alanine.
Thus, at every position where an alanine is specified by a codon,
the codon can be altered to any of the corresponding codons
described without altering the encoded polypeptide. Such nucleic
acid variations are "silent variations," which are one species of
conservatively modified variations. Every nucleic acid sequence
herein which encodes a polypeptide also describes every possible
silent variation of the nucleic acid. One of skill will recognize
that each codon in a nucleic acid (except AUG, which is ordinarily
the only codon for methionine, and TGG, which is ordinarily the
only codon for tryptophan) can be modified to yield a functionally
identical molecule. Accordingly, each silent variation of a nucleic
acid that encodes a polypeptide is implicit in each described
sequence.
[0084] For polypeptide sequences, "conservatively modified
variants" include individual substitutions, deletions or additions
to a polypeptide sequence which result in the substitution of an
amino acid with a chemically similar amino acid. Conservative
substitution tables providing functionally similar amino acids are
well known in the art. Such conservatively modified variants are in
addition to and do not exclude polymorphic variants, interspecies
homologs, and alleles of the invention. The following eight groups
contain amino acids that are conservative substitutions for one
another: 1) Alanine (A), Glycine (G); 2) Aspartic acid (D),
Glutamic acid (E); 3) Asparagine (N), Glutamine (Q); 4) Arginine
(R), Lysine (K); 5) Isoleucine (I), Leucine (L), Methionine (M),
Valine (V); 6) Phenylalanine (F), Tyrosine (Y), Tryptophan (W); 7)
Serine (S), Threonine (T); and 8) Cysteine (C), Methionine (M)
(see, e.g., Creighton, Proteins (1984)). In some embodiments, the
term "conservative sequence modifications" are used to refer to
amino acid modifications that do not significantly affect or alter
the binding characteristics of the antibody containing the amino
acid sequence.
[0085] The terms "cross-compete" and "cross-competing" are used
interchangeably herein to mean the ability of an antibody or other
binding agent to interfere with the binding of other antibodies or
binding agents to HER3 in a standard competitive binding assay.
[0086] The ability or extent to which an antibody or other binding
agent is able to interfere with the binding of another antibody or
binding molecule to HER3, and therefore whether it can be said to
cross-compete according to the invention, can be determined using
standard competition binding assays. One suitable assay involves
the use of the Biacore technology (e.g. by using the BIAcore 3000
instrument (Biacore, Uppsala, Sweden)), which can measure the
extent of interactions using surface plasmon resonance technology.
Another assay for measuring cross-competing uses an ELISA-based
approach.
[0087] The term "optimized" as used herein refers to a nucleotide
sequence has been altered to encode an amino acid sequence using
codons that are preferred in the production cell or organism,
generally a eukaryotic cell, for example, a cell of Pichia, a cell
of Trichoderma, a Chinese Hamster Ovary cell (CHO) or a human cell.
The optimized nucleotide sequence is engineered to retain
completely or as much as possible the amino acid sequence
originally encoded by the starting nucleotide sequence, which is
also known as the "parental" sequence.
[0088] Standard assays to evaluate the binding ability of the
antibodies toward HER3 of various species are known in the art,
including for example, ELISAs, western blots and RIAs. Suitable
assays are described in detail in the Examples. The binding
kinetics (e.g., binding affinity) of the antibodies also can be
assessed by standard assays known in the art, such as by Biacore
analysis, or FACS relative affinity (Scatchard). Assays to evaluate
the effects of the antibodies on functional properties of HER3
(e.g., receptor binding assays, modulating the Her pathway) are
described in further detail in the Examples.
[0089] The phrases "percent identical" or "percent identity," in
the context of two or more nucleic acids or polypeptide sequences,
refers to two or more sequences or subsequences that are the same.
Two sequences are "substantially identical" if two sequences have a
specified percentage of amino acid residues or nucleotides that are
the same (i.e., 60% identity, optionally 65%, 70%, 75%, 80%, 85%,
90%, 95%, or 99% identity over a specified region, or, when not
specified, over the entire sequence), when compared and aligned for
maximum correspondence over a comparison window, or designated
region as measured using one of the following sequence comparison
algorithms or by manual alignment and visual inspection.
Optionally, the identity exists over a region that is at least
about 50 nucleotides (or 10 amino acids) in length, or more
preferably over a region that is 100 to 500 or 1000 or more
nucleotides (or 20, 50, 200 or more amino acids) in length.
[0090] For sequence comparison, typically one sequence acts as a
reference sequence, to which test sequences are compared. When
using a sequence comparison algorithm, test and reference sequences
are entered into a computer, subsequence coordinates are
designated, if necessary, and sequence algorithm program parameters
are designated. Default program parameters can be used, or
alternative parameters can be designated. The sequence comparison
algorithm then calculates the percent sequence identities for the
test sequences relative to the reference sequence, based on the
program parameters.
[0091] A "comparison window", as used herein, includes reference to
a segment of any one of the number of contiguous positions selected
from the group consisting of from 20 to 600, usually about 50 to
about 200, more usually about 100 to about 150 in which a sequence
may be compared to a reference sequence of the same number of
contiguous positions after the two sequences are optimally aligned.
Methods of alignment of sequences for comparison are well known in
the art. Optimal alignment of sequences for comparison can be
conducted, e.g., by the local homology algorithm of Smith and
Waterman, (1970) Adv. Appl. Math. 2:482c, by the homology alignment
algorithm of Needleman and Wunsch, (1970) J. Mol. Biol. 48:443, by
the search for similarity method of Pearson and Lipman, (1988)
Proc. Nat'l. Acad. Sci. USA 85:2444, by computerized
implementations of these algorithms (GAP, BESTFIT, FASTA, and
TFASTA in the Wisconsin Genetics Software Package, Genetics
Computer Group, 575 Science Dr., Madison, Wis.), or by manual
alignment and visual inspection (see, e.g., Brent et al., (2003)
Current Protocols in Molecular Biology).
[0092] Two examples of algorithms that are suitable for determining
percent sequence identity and sequence similarity are the BLAST and
BLAST 2.0 algorithms, which are described in Altschul et al.,
(1977) Nuc. Acids Res. 25:3389-3402; and Altschul et al., (1990) J.
Mol. Biol. 215:403-410, respectively. Software for performing BLAST
analyses is publicly available through the National Center for
Biotechnology Information. This algorithm involves first
identifying high scoring sequence pairs (HSPs) by identifying short
words of length W in the query sequence, which either match or
satisfy some positive-valued threshold score T when aligned with a
word of the same length in a database sequence. T is referred to as
the neighborhood word score threshold (Altschul et al., supra).
These initial neighborhood word hits act as seeds for initiating
searches to find longer HSPs containing them. The word hits are
extended in both directions along each sequence for as far as the
cumulative alignment score can be increased. Cumulative scores are
calculated using, for nucleotide sequences, the parameters M
(reward score for a pair of matching residues; always >0) and N
(penalty score for mismatching residues; always <0). For amino
acid sequences, a scoring matrix is used to calculate the
cumulative score. Extension of the word hits in each direction are
halted when: the cumulative alignment score falls off by the
quantity X from its maximum achieved value; the cumulative score
goes to zero or below, due to the accumulation of one or more
negative-scoring residue alignments; or the end of either sequence
is reached. The BLAST algorithm parameters W, T, and X determine
the sensitivity and speed of the alignment. The BLASTN program (for
nucleotide sequences) uses as defaults a wordlength (W) of 11, an
expectation (E) or 10, M=5, N=-4 and a comparison of both strands.
For amino acid sequences, the BLASTP program uses as defaults a
wordlength of 3, and expectation (E) of 10, and the BLOSUM62
scoring matrix (see Henikoff and Henikoff, (1989) Proc. Natl. Acad.
Sci. USA 89:10915) alignments (B) of 50, expectation (E) of 10,
M=5, N=-4, and a comparison of both strands.
[0093] The BLAST algorithm also performs a statistical analysis of
the similarity between two sequences (see, e.g., Karlin and
Altschul, (1993) Proc. Natl. Acad. Sci. USA 90:5873-5787). One
measure of similarity provided by the BLAST algorithm is the
smallest sum probability (P(N)), which provides an indication of
the probability by which a match between two nucleotide or amino
acid sequences would occur by chance. For example, a nucleic acid
is considered similar to a reference sequence if the smallest sum
probability in a comparison of the test nucleic acid to the
reference nucleic acid is less than about 0.2, more preferably less
than about 0.01, and most preferably less than about 0.001.
[0094] The percent identity between two amino acid sequences can
also be determined using the algorithm of E. Meyers and W. Miller,
(1988) Comput. Appl. Biosci. 4:11-17) which has been incorporated
into the ALIGN program (version 2.0), using a PAM120 weight residue
table, a gap length penalty of 12 and a gap penalty of 4. In
addition, the percent identity between two amino acid sequences can
be determined using the Needleman and Wunsch (1970) J. Mol. Biol.
48:444-453) algorithm which has been incorporated into the GAP
program in the GCG software package (available at www.gcg.com),
using either a Blossom 62 matrix or a PAM250 matrix, and a gap
weight of 16, 14, 12, 10, 8, 6, or 4 and a length weight of 1, 2,
3, 4, 5, or 6.
[0095] Other than percentage of sequence identity noted above,
another indication that two nucleic acid sequences or polypeptides
are substantially identical is that the polypeptide encoded by the
first nucleic acid is immunologically cross reactive with the
antibodies raised against the polypeptide encoded by the second
nucleic acid, as described below. Thus, a polypeptide is typically
substantially identical to a second polypeptide, for example, where
the two peptides differ only by conservative substitutions. Another
indication that two nucleic acid sequences are substantially
identical is that the two molecules or their complements hybridize
to each other under stringent conditions, as described below. Yet
another indication that two nucleic acid sequences are
substantially identical is that the same primers can be used to
amplify the sequence.
[0096] The phrase "nucleic acid" is used herein interchangeably
with the term "polynucleotide" and refers to deoxyribonucleotides
or ribonucleotides and polymers thereof in either single- or
double-stranded form. The term encompasses nucleic acids containing
known nucleotide analogs or modified backbone residues or linkages,
which are synthetic, naturally occurring, and non-naturally
occurring, which have similar binding properties as the reference
nucleic acid, and which are metabolized in a manner similar to the
reference nucleotides. Examples of such analogs include, without
limitation, phosphorothioates, phosphoramidates, methyl
phosphonates, chiral-methyl phosphonates, 2-O-methyl
ribonucleotides, peptide-nucleic acids (PNAs).
[0097] Unless otherwise indicated, a particular nucleic acid
sequence also implicitly encompasses conservatively modified
variants thereof (e.g., degenerate codon substitutions) and
complementary sequences, as well as the sequence explicitly
indicated. Specifically, as detailed below, degenerate codon
substitutions may be achieved by generating sequences in which the
third position of one or more selected (or all) codons is
substituted with mixed-base and/or deoxyinosine residues (Batzer et
al., (1991) Nucleic Acid Res. 19:5081; Ohtsuka et al., (1985) J.
Biol. Chem. 260:2605-2608; and Rossolini et al., (1994) Mol. Cell.
Probes 8:91-98).
[0098] The phrase "operably linked" refers to a functional
relationship between two or more polynucleotide (e.g., DNA)
segments. Typically, it refers to the functional relationship of a
transcriptional regulatory sequence to a transcribed sequence. For
example, a promoter or enhancer sequence is operably linked to a
coding sequence if it stimulates or modulates the transcription of
the coding sequence in an appropriate host cell or other expression
system. Generally, promoter transcriptional regulatory sequences
that are operably linked to a transcribed sequence are physically
contiguous to the transcribed sequence, i.e., they are cis-acting.
However, some transcriptional regulatory sequences, such as
enhancers, need not be physically contiguous or located in close
proximity to the coding sequences whose transcription they
enhance.
[0099] The terms "polypeptide" and "protein" are used
interchangeably herein to refer to a polymer of amino acid
residues. The terms apply to amino acid polymers in which one or
more amino acid residue is an artificial chemical mimetic of a
corresponding naturally occurring amino acid, as well as to
naturally occurring amino acid polymers and non-naturally occurring
amino acid polymer. Unless otherwise indicated, a particular
polypeptide sequence also implicitly encompasses conservatively
modified variants thereof.
[0100] The term "subject" includes human and non-human animals.
Non-human animals include all vertebrates, e.g., mammals and
non-mammals, such as non-human primates, sheep, dog, cow, chickens,
amphibians, and reptiles. Except when noted, the terms "patient" or
"subject" are used herein interchangeably.
[0101] The term "anti-cancer agent" means any agent that can be
used to treat a cell proliferative disorder such as cancer,
including cytotoxic agents, chemotherapeutic agents, radiotherapy
and radiotherapeutic agents, targeted anti-cancer agents, and
immunotherapeutic agents.
[0102] "Tumor" refers to neoplastic cell growth and proliferation,
whether malignant or benign, and all pre-cancerous and cancerous
cells and tissues.
[0103] The term "anti-tumor activity" means a reduction in the rate
of tumor cell proliferation, viability, or metastatic activity. A
possible way of showing anti-tumor activity is show a decline in
growth rate of abnormal cells that arises during therapy or tumor
size stability or reduction. Such activity can be assessed using
accepted in vitro or in vivo tumor models, including but not
limited to xenograft models, allograft models, MMTV models, and
other known models known in the art to investigate anti-tumor
activity.
[0104] The term "malignancy" refers to a non-benign tumor or a
cancer. As used herein, the term "cancer" includes a malignancy
characterized by deregulated or uncontrolled cell growth.
[0105] Exemplary cancers include: carcinomas, sarcomas, leukemias,
and lymphomas. The term "cancer" includes primary malignant tumors
(e.g., those whose cells have not migrated to sites in the
subject's body other than the site of the original tumor) and
secondary malignant tumors (e.g., those arising from metastasis,
the migration of tumor cells to secondary sites that are different
from the site of the original tumor).
[0106] Various aspects of the invention are described in further
detail in the following sections and subsections.
Structure and Mechanism of Activation of the HER Receptors
[0107] All four HER receptors have an extracellular ligand-binding
domain, a single trans-membrane domain and a cytoplasmic tyrosine
kinase-containing domain. The intracellular tyrosine kinase domain
of HER receptors is highly conserved, although the kinase domain of
HER3 contains substitutions of critical amino acids and therefore
lacks kinase activity (Guy et al., (1994): PNAS 91, 8132-8136).
Ligand-induced dimerisation of the HER receptors induces activation
of the kinase, receptor transphosphorylation on tyrosine residues
in the C-terminal tail, followed by recruitment and activation of
intracellular signalling effectors (Yarden and Sliwkowski, (2001)
Nature Rev 2, 127-137; Jorissen et al., (2003) Exp Cell Res 284,
31-53.
[0108] The crystal structures of the extracellular domains of HERs
have provided some insight into the process of ligand-induced
receptor activation (Schlessinger, (2002) Cell 110, 669-672). The
extracellular domain of each HER receptor consists of four
subdomains: Subdomain I and III cooperate in forming the
ligand-binding site, whereas subdomain II (and perhaps also
subdomain IV) participates in receptor dimerisation via direct
receptor-receptor interactions. In the structures of ligand-bound
HER1, a .beta. hairpin (termed the dimerisation loop) in subdomain
II interacts with the dimerisation loop of the partner receptor,
mediating receptor dimerisation (Garrett et al, (2002) Cell 110,
763-773; Ogiso et al., (2002) Cell 110, 775-787). In contrast, in
the structures of the inactive HER1, HER3 and HER4, the
dimerisation loop is engaged in intramolecular interactions with
subdomain IV, which prevents receptor dimerisation in the absence
of ligand (Cho and Leahy, (2002) Science 297, 1330-1333; Ferguson
et al., (2003) Mol Cell 12, 541-552; Bouyan et al., (2005) PNAS
102, 15024-15029). The structure of HER2 is unique among the HERs.
In the absence of a ligand, HER2 has a conformation that resembles
the ligand-activated state of HER1 with a protruding dimerisation
loop, available to interact with other HER receptors (Cho et al.,
(2003) Nature 421, 756-760; Garrett et al., (2003) Mol Cell 11,
495-505). This may explain the enhanced heterodimerisation capacity
of HER2.
[0109] Although the HER receptor crystal structures provide a model
for HER receptor homo- and heterodimerisation, the background for
the prevalence of some HER homo- and heterodimers over others
(Franklin et al., (2004) Cancer Cell 5, 317-328) as well as the
conformational role of each of the domain in receptor dimerisation
and autoinhibition (Burgess et al., (2003) Mol Cell 12, 541-552;
Mattoon et al., (2004) PNAS 101, 923-928) remains somewhat unclear.
As described below, the HER3 X-ray crystal structure provides more
insights.
HER3 Structure and Conformational Epitopes
[0110] A conformational epitope to which antigen binding proteins,
e.g., anti-HER3 antibodies bind is provided herein. For the first
time, the three dimensional structure of a truncated form (residues
20-640) of the extracellular domain of HER3 complexed with an
antibody have been shown. The HER3-MOR09823 Fab complex and the
HER3-MOR09825 have been determined at 3.2 .ANG. and 3.4 .ANG.
resolution, respectively, and shown in FIG. 5A. The disclosure
herein also shows for the first time an antibody or fragment
thereof that binds to an inactive state of HER3 and stabilizes the
receptor in the inactive state. The antibodies of the invention
also permit concurrent binding of a HER3 ligand, such as neuregulin
with the HER3 receptor.
[0111] Although not bound to provide a theory, one possible model
for the mechanism of action is that HER3 typically exists in an
inactive (closed, tethered) or active (open) state. Ligand binding
induces a conformational change such that HER3 exists in the active
(open) state which is capable of binding heterodimer partners
resulting in activation in downstream signaling. Antibodies such as
MOR09823 bind the inactive (tethered) state of HER3 but do not
block the ligand binding site. Antibodies such as MOR09823 inhibit
HER3 by preventing the ligand induced structural rearrangements
required for HER3 to transition to the active conformation, thereby
preventing signal transduction. In one embodiment, the antibodies
of the invention or fragments thereof bind the inactive (tethered)
state of HER3 but do not block the ligand binding site. In another
embodiment, the antibodies or fragments thereof inhibit HER3 by
preventing the ligand-induced structural rearrangements required
for HER3 to transition to the active conformation, thereby
preventing signal transduction. In another embodiment, the antibody
or fragment thereof stabilizes (directly maintains, locks, tethers,
holds, preferentially binds, or favors) HER3 receptor in the
inactive state or conformation. In one embodiment, the inactive
HER3 receptor may be susceptible to preferential internalization or
degradation such that it leads to loss of cell surface HER3
receptors. The biological data presented in the Examples section
supports these embodiments.
[0112] The crystals of HER3 may be prepared by expressing a
nucleotide sequence encoding HER3 or a variant thereof in a
suitable host cell, and then crystallising the purified protein(s)
in the presence of the relevant HER3 targeted Fab. Preferably the
HER3 polypeptide contains the extracellular domain (amino acids 20
to 640 of the human polypeptide or a truncated version thereof,
preferably comprising amino acids 20-640) but lacks the
transmembrane and intracellular domains.
[0113] HER3 polypeptides may also be produced as fusion proteins,
for example to aid in extraction and purification. Examples of
fusion protein partners include glutathione-S-transferase (GST),
histidine (HIS), hexahistidine (6HIS) (SEQ ID NO: 495), GAL4 (DNA
binding and/or transcriptional activation domains) and
beta-galactosidase. It may also be convenient to include a
proteolytic cleavage site between the fusion protein partner and
the protein sequence of interest to allow removal of fusion protein
sequences.
[0114] After expression, the proteins may be purified and/or
concentrated, for example by immobilised metal affinity
chromatography, ion-exchange chromatography, and/or gel
filtration.
[0115] The protein(s) may be crystallised using techniques
described herein. Commonly, in a crystallisation process, a drop
containing the protein solution is mixed with the crystallisation
buffer and allowed to equilibrate in a sealed container.
Equilibration may be achieved by known techniques such as the
"hanging drop" or the "sitting drop" method. In these methods, the
drop is hung above or sitting beside a much larger reservoir of
crystallization buffer and equilibration is reached through vapor
diffusion. Alternatively, equilibration may occur by other methods,
for example under oil, through a semi-permeable membrane, or by
free-interface diffusion (See e.g., Chayen et al., (2008) Nature
Methods 5, 147-153.
[0116] Once the crystals have been obtained, the structure may be
solved by known X-ray diffraction techniques. Many techniques use
chemically modified crystals, such as those modified by heavy atom
derivatization to approximate phases. In practice, a crystal is
soaked in a solution containing heavy metal atom salts, or
organometallic compounds, e.g., lead chloride, gold thiomalate,
thimerosal or uranyl acetate, which can diffuse through the crystal
and bind to the surface of the protein. The location(s) of the
bound heavy metal atom(s) can then be determined by X-ray
diffraction analysis of the soaked crystal. The patterns obtained
on diffraction of a monochromatic beam of X-rays by the atoms
(scattering centres) of the crystal can be solved by mathematical
equations to give mathematical coordinates. The diffraction data
are used to calculate an electron density map of the repeating unit
of the crystal. Another method of obtaining phase information is
using a technique known as molecular replacement. In this method,
rotational and translational algorithms are applied to a search
model derived from a related structure, resulting in an approximate
orientation for the protein of interest (See Rossmann, (1990) Acta
Crystals A 46, 73-82). The electron density maps are used to
establish the positions of the individual atoms within the unit
cell of the crystal (Blundel et al., (1976) Protein
Crystallography, Academic Press).
[0117] The present disclosure describes for the first time, the
three-dimensional structure of HER3 and a Fab of an anti-HER3
antibody. The approximate domain boundaries of extracellular domain
of HER3 are as follows; domain 1: amino acids 20-207; domain 2:
amino acids 208-328; domain 3: amino acids 329-498; and domain 4:
amino acids 499-642. The three-dimensional structure of HER3 and
the antibody also allows the identification of target binding sites
for potential HER3 modulators. Preferred target binding sites are
those involved in the activation of HER3. In one embodiment, the
target binding site is located within domain 2 and domain 4 of
HER3. Thus an antibody or fragment thereof which binds to either
domain 2 or domain 4, and preferably to both domains can modulate
HER3 activation by either preventing the domains from dissociation
from each other or by modifying the relative positions of the
domains. Thus binding an antibody or fragment thereof to amino acid
residues within domain 2 or domain 4 may cause the protein to adopt
a conformation that prevents activation. The disclosure herein also
shows for the first time an antibody or fragment thereof that can
concurrently bind with a HER3 ligand, such as neuregulin.
[0118] In some embodiments, the antibody or fragment thereof
recognize a specific conformational state of HER3 such that the
antibody or fragment thereof prevents HER3 from interacting with a
co-receptor (including, but not limited to, HER1, HER2 and HER4).
In some embodiments, the antibody or fragment thereof prevents HER3
from interacting with a co-receptor by stabilizing the HER3
receptor in an inactive or closed state. In one embodiment, the
antibody or fragment thereof stabilizes the HER3 receptor by
binding to amino acid residues within domain 2 and domain 4 of
HER3. In this inactive state, the dimerization loop located within
domain 2 is not exposed and therefore unavailable for dimerization
with other co-receptors (including, but not limited to, HER1, HER2
and HER4). In some embodiments, the antibody or fragment thereof
binds to human HER3 protein having a conformational epitope
comprising (i) HER3 amino acid residues 265-277 and 315 (of domain
2) and (ii) HER3 amino acid residues 571, 582-584, 596-597,
600-602, 609-615 (of domain 4) of SEQ ID NO: 1, or a subset
thereof. In some embodiments, the antibody or fragment thereof
binds to amino acids within or overlapping amino acid residues
265-277 and 315 (of domain 2) and (ii) HER3 amino acid residues
571, 582-584, 596-597, 600-602, 609-615 (of domain 4) of SEQ ID NO:
1. In some embodiments, the antibody or fragment thereof binds to
amino acids within (and/or amino acid sequences consisting of)
amino acids 265-277 and 315 (of domain 2) and (ii) HER3 amino acid
residues 571, 582-584, 596-597, 600-602, 609-615 (of domain 4) of
SEQ ID NO: 1, or a subset thereof. In some embodiments, the
antibody or fragment thereof binds to the conformational epitope
such that it restricts the mobility of domain 2 and domain 4,
stabilizing it in an inactive or closed conformation. The failure
to form the active conformation results in failure to activate
signal transduction. In some embodiments, the antibody or fragment
thereof binds to the conformational epitope such that it occludes
the dimerization loop within domain 2, thereby rendering it
unavailable for receptor-receptor interaction. The failure to form
homo- or heterodimers results in failure to activate signal
transduction.
[0119] In another aspect, the antibody or fragment thereof binds a
conformational epitope of HER receptor, such as a HER3 receptor. In
one embodiment, the antibody or fragment thereof stabilizes the
HER3 receptor in the inactive state. In another embodiment, the
antibody or fragment thereof binds to the active state of the HER3
receptor and drives it into the inactive state as the inactive
state. Thus, the antibody or fragment thereof can bind to either
the active or inactive state of HER3, but favors the formation of
the inactive state and drives the active state of HER3 into the
inactive state, resulting in a failure to activate signal
transduction.
[0120] In another aspect, the antibody or fragment thereof binds a
conformational epitope of HER receptor, such as a HER3 receptor
where binding of the antibody or fragment thereof stabilizes the
HER3 receptor in an inactive state such that the HER3 receptor
fails to dimerize with a co-receptor to form a receptor-receptor
complex. The failure to form a receptor-receptor complex prevents
activation of both ligand-dependent and ligand-independent signal
transduction.
[0121] In another aspect, the antibody or fragment thereof binds a
conformational epitope of HER receptor such as a HER3 receptor,
where binding of the antibody or fragment thereof to the HER3
receptor allows dimerization with a co-receptor to form an inactive
receptor-receptor complex. The formation of the inactive
receptor-receptor complex prevents activation of ligand-independent
signal transduction. For example, in ligand-independent signal
transduction, HER3 may exists in an inactive state, however the
overexpression of HER2 causes HER2-HER3 complex formation, however
these resulting complexes are inactive and prevent activation of
ligand-independent signal transduction.
[0122] The depicted structure also allows one to identify specific
core HER3 amino acid residues for the interaction interface of an
antibody or fragment thereof (e.g., MOR09823) with HER3. This was
defined as residues that are within 5 .ANG. of the MOR09823 protein
VH chain. The core residues are as follows: Asn266, Lys267, Leu268,
Thr269, Gln271, Glu273, Pro274, Asn275, Pro276, His277, Asn315,
Asp571, Pro583, His584, Ala596, Lys597 (residues of SEQ ID NO:
1).
[0123] The structures can also used to identify boundary HER3 amino
acid residues for the interaction interface with an antibody or
fragment thereof (e.g., MOR09823). These residues can be HER3
residues that were 5-8 .ANG. from the MOR09823 protein VH chain.
The boundary residues are as follows: Pro262, Val264, Tyr265,
Phe270, Leu272, Thr278, Lys314, Gly316, Glu321, Asn566, Ser568,
Gly569, Ser570, Thr572, Arg580, Asp581, Gly582, Gly595, Gly598,
Ile600 (residues of SEQ ID NO: 1).
[0124] The depicted structure also allows one to identify specific
core HER3 amino acid residues for the interaction interface of an
antibody or fragment thereof (e.g., MOR09823) with HER3. This was
defined as residues that are within 5 .ANG. of the MOR09823 protein
VL chain. The core residues are as follows: Tyr265, Lys267, Leu268,
Phe270, Gly582, Pro583, Lys597, Ile600, Lys602, Glu609, Arg611,
Pro612, Cys613, His614, Glu615 (residues of SEQ ID NO: 1).
[0125] The structures were also used to identify boundary HER3
amino acid residues for the interaction interface with an antibody
or fragment thereof (e.g., MOR09823). These residues were HER3
residues that were 5-8 .ANG. from the MOR09823 protein VL chain.
The boundary residues are as follows: Asn266, Thr269, Asp571,
Arg580, Asp581, His584, Pro590, Ala596, Pro599, Tyr601, Tyr603,
Asp605, Gln607, Cys610, Asn616, Cys617, Cys621, Gly623, Pro624
(residues of SEQ ID NO: 1).
[0126] As can be seen in Tables 11 and 12 (MOR09823) and Tables 13
and 14 (MOR09825), respectively, the heavy chain is mainly involved
in the antigen binding protein's binding to amino acid residues
within domain 2 of the epitope with fewer interactions with amino
acid residues of domain 4, while the light chain is mainly involved
with binding to amino acid residues within domain 4 of the epitope
with fewer interactions with amino acid residues within domain
2.
[0127] As such, one of skill in the art, given the present
teachings, can predict which residues and areas of the antigen
binding proteins can be varied without unduly interfering with the
antigen binding protein's ability to bind to HER3.
[0128] Core interaction interface amino acids were determined as
being all amino acid residues with at least one atom less than or
equal to 5 .ANG. from the HER3 partner protein. 5 .ANG. was chosen
as the core region cutoff distance to allow for atoms within a van
der Waals radius plus a possible water-mediated hydrogen bond.
Boundary interaction interface amino acids were determined as all
amino acid residues with at least one atom less than or equal to 8
.ANG. from the HER3 partner protein but not included in the core
interaction list.
[0129] In some embodiments, any antigen binding protein that binds
to, covers, or prevents MOR09823 from interacting with any of the
above residues can be employed to bind to or neutralize HER3. In
some embodiments, the antibodies or fragments thereof binds to or
interacts with at least one of the following HER3 residues (SEQ ID
NO: 1): Asn266, Lys267, Leu268, Thr269, Gln271, Glu273, Pro274,
Asn275, Pro276, His277, Asn315, Asp571, Pro583, His584, Ala596,
Lys597. In some embodiments, the antibodies and fragments thereof
binds to or interacts with at least one of the following HER3
residues (SEQ ID NO: 1): Tyr265, Lys267, Leu268, Phe270, Gly582,
Pro583, Lys597, Ile600, Lys602, Glu609, Arg611, Pro612, Cys613,
His614, Glu615. In some embodiments, the antibodies or fragments
thereof binds to or interacts with at least one of the following
HER3 residues (SEQ ID NO: 1): Asn266, Lys267, Leu268, Thr269,
Gln271, Glu273, Pro274, Asn275, Pro276, His277, Asn315, Asp571,
Pro583, His584, Ala596, Lys597, Tyr265, Lys267, Leu268, Phe270,
Gly582, Pro583, Lys597, Ile600, Lys602, Glu609, Arg611, Pro612,
Cys613, His614, Glu615. In some embodiments, the antibodies or
fragments thereof binds to or interacts with a combination of the
following HER3 residues (SEQ ID NO: 1): Asn266, Lys267, Leu268,
Thr269, Gln271, Glu273, Pro274, Asn275, Pro276, His277, Asn315,
Asp571, Pro583, His584, Ala596, Lys597, Tyr265, Lys267, Leu268,
Phe270, Gly582, Pro583, Lys597, Ile600, Lys602, Glu609, Arg611,
Pro612, Cys613, His614, Glu615. In some embodiments, the antibodies
or fragments thereof binds to or interacts with all of the
following HER3 residues (SEQ ID NO: 1): Asn266, Lys267, Leu268,
Thr269, Gln271, Glu273, Pro274, Asn275, Pro276, His277, Asn315,
Asp571, Pro583, His584, Ala596, Lys597, Tyr265, Lys267, Leu268,
Phe270, Gly582, Pro583, Lys597, Ile600, Lys602, Glu609, Arg611,
Pro612, Cys613, His614, Glu615. In some embodiments, the antibody
or fragment thereof is within 5 angstroms of one or more of the
above residues. In some embodiments, the antibody or fragment
thereof is 5 to 8 angstroms from one or more of the above residues.
In some embodiments, the antibody or fragment thereof interacts,
blocks, or is within 8 angstroms of 1, 2, 3, 4, 5, 6, 7, 8, 9, 10,
11, 12, 13, 14, 15, 20, 25, 30, 35, 40, 45, or 50 of the above
residues.
[0130] The availability of 3D structures for the HER3 and the
complex of HER3:MOR09823, for example, provides the framework to
explore other HER3 antibodies in more detail. The 3D structure of
HER3 allows the epitopes for monoclonal antibodies to be mapped and
their mode of action inferred, since some inhibit, some stimulate
and others have no effect on cell growth. The conformational
epitope for MOR09823 has been located to the domains 2 and 4 of
HER3. The availability of the 3D structures of this receptor will
facilitate the determination of the precise mechanism of action of
these inhibitory agents and the design of new approaches to
interfering with HER3 receptor function. In one embodiment, the
antibodies of the invention bind to the same conformational epitope
as MOR09823.
[0131] In some embodiments, the conformational epitope bound by any
of the antibodies listed in Table 1 is especially useful. In
certain embodiments, a HER3 conformational epitope can be utilized
to isolate antibodies of fragments thereof that bind to HER3. In
certain embodiments, a HER3 conformational epitope can be utilized
to generate antibodies or fragments thereof which bind to HER3. In
certain embodiments, a HER3 conformational epitope can be utilized
as an immunogen to generate antibodies of fragments thereof that
bind to the HER3 conformational epitope. In certain embodiments, a
HER3 conformational epitope can be administered to an animal, and
antibodies that bind to HER3 can subsequently be obtained from the
animal.
[0132] In some embodiments, the domain(s)/region(s) containing
residues that are in contact with or are buried by an antibody can
be identified by mutating specific residues in HER3 (e.g., a
wild-type antigen) and determining whether antibody or fragment
thereof can bind the mutated or variant HER3 protein or measure
changes of affinity from wild-type. By making a number of
individual mutations, residues that play a direct role in binding
or that are in sufficiently close proximity to the antibody such
that a mutation can affect binding between the antibody and antigen
can be identified. From a knowledge of these amino acids, the
domain(s) or region(s) of the antigen (HER3) that contain residues
in contact with the antibody or covered by the antibody can be
elucidated. Mutagenesis using known techniques such as
alanine-scanning can help define functionally relevant epitopes.
Mutagenesis utilizing an arginine/glutamic acid scanning protocol
can also be employed (see, e.g., Nanevicz et al., (1995), J. Biol.
Chem. 270(37):21619-21625 and Zupnick et al., (2006), J. Biol.
Chem. 281(29):20464-20473). In general, arginine and glutamic acids
are substituted (typically individually) for an amino acid in the
wild-type polypeptide because these amino acids are charged and
bulky and thus have the potential to disrupt binding between an
antigen binding protein and an antigen in the region of the antigen
where the mutation is introduced. Arginines that exist in the
wild-type antigen are replaced with glutamic acid. A variety of
such individual mutants can be obtained and the collected binding
results analyzed to determine what residues affect binding. A
series of mutant HER3 antigens can be created, with each mutant
antigen having a single mutation. Binding of each mutant HER3
antigen with various HER3 antibodies or fragments thereof can be
measured and compared to the ability of the selected an antibody or
fragments thereof to bind wild-type HER3 (SEQ ID NO: 1).
[0133] An alteration (for example a reduction or increase) in
binding between an antibody or fragment thereof and a mutant or
variant HER3 as used herein means that there is a change in binding
affinity (e.g., as measured by known methods such as Biacore
testing or the bead based assay described below in the examples),
EC.sub.50, and/or a change (for example a reduction) in the total
binding capacity of the antigen binding protein (for example, as
evidenced by a decrease in B.sub.max in a plot of antigen binding
protein concentration versus antigen concentration). A significant
alteration in binding indicates that the mutated residue is
involved in binding to the antibody or fragment thereof.
[0134] In some embodiments, a significant reduction in binding
means that the binding affinity, EC.sub.50, and/or capacity between
an antibody or fragments thereof and a mutant HER3 antigen is
reduced by greater than 10%, greater than 20%, greater than 40%,
greater than 50%, greater than 55%, greater than 60%, greater than
65%, greater than 70%, greater than 75%, greater than 80%, greater
than 85%, greater than 90% or greater than 95% relative to binding
between the an antibody or fragment thereof and a wild type HER3
(e.g., SEQ ID NO: 1).
[0135] In some embodiments, binding of an antibody or fragments
thereof is significantly reduced or increased for a mutant HER3
protein having one or more (e.g., 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, or
more) mutations as compared to a wild-type HER3 protein (e.g., SEQ
ID NO: 1).
[0136] Although the variant forms are referenced with respect to
the wild-type sequence shown in SEQ ID NO: 1, it will be
appreciated that in an allelic or splice variants of HER3 the amino
acids could differ. Antibodies or fragments thereof showing
significantly altered binding (e.g., lower or higher binding) for
such allelic forms of HER3 are also contemplated.
[0137] In addition to the general structural aspects of antibodies,
the more specific interaction between the paratope and the epitope
may be examined through structural approaches. In one embodiment,
the structure of the CDRs contribute to a paratope, through which
an antibody is able to bind to an epitope. The shape of such a
paratope may be determined in a number of ways. Traditional
structural examination approaches can be used, such as NMR or x-ray
crystallography. These approaches can examine the shape of the
paratope alone, or while it is bound to the epitope. Alternatively,
molecular models may be generated in silico. A structure can be
generated through homology modeling, aided with a commercial
package, such as InsightII modeling package from Accelrys (San
Diego, Calif.). Briefly, one can use the sequence of the antibody
to be examined to search against a database of proteins of known
structures, such as the Protein Data Bank. After one identifies
homologous proteins with known structures, these homologous
proteins are used as modeling templates. Each of the possible
templates can be aligned, thus producing structure based sequence
alignments among the templates. The sequence of the antibody with
the unknown structure can then be aligned with these templates to
generate a molecular model for the antibody with the unknown
structure. As will be appreciated by one of skill in the art, there
are many alternative methods for generating such structures in
silico, any of which may be used. For instance, a process similar
to the one described in Hardman et al., issued U.S. Pat. No.
5,958,708 employing QUANTA (Polygen Corp., Waltham, Mass.) and
CHARM (Brooks et al., (1983), J. Comp. Chem. 4:187) may be used
(hereby incorporated in its entirety by reference).
[0138] Not only is the shape of the paratope important in
determining whether and how well a possible paratope will bind to
an epitope, but the interaction itself, between the epitope and the
paratope is a source of great information in the design of variant
antibodies. As appreciated by one of skill in the art, there are a
variety of ways in which this interaction can be studied. One way
is to use the structural model generated, perhaps as described
above, and then to use a program such as InsightII (Accelrys, San
Diego, Calif.), which has a docking module, which, among other
things, is capable of performing a Monte Carlo search on the
conformational and orientational spaces between the paratope and
its epitope. The result is that one is able to estimate where and
how the epitope interacts with the paratope. In one embodiment,
only a fragment, or variant, of the epitope is used to assist in
determining the relevant interactions. In one embodiment, the
entire epitope is used in the modeling of the interaction between
the paratope and the epitope.
[0139] Through the use of these modelled structures, one is able to
predict which residues are the most important in the interaction
between the epitope and the paratope. Thus, in one embodiment, one
is able to readily select which residues to change in order to
alter the binding characteristics of the antibody. For instance, it
may be apparent from the docking models that the side chains of
certain residues in the paratope may sterically hinder the binding
of the epitope, thus altering these residues to residues with
smaller side chains may be beneficial. One can determine this in
many ways. For example, one may simply look at the two models and
estimate interactions based on functional groups and proximity.
Alternatively, one may perform repeated pairings of epitope and
paratope, as described above, in order to obtain more favorable
energy interactions. One can also determine these interactions for
a variety of variants of the antibody to determine alternative ways
in which the antibody may bind to the epitope. One can also combine
the various models to determine how one should alter the structure
of the antibodies in order to obtain an antibody with the
particular characteristics that are desired.
[0140] The models determined above can be tested through various
techniques. For example, the interaction energy can determined with
the programs discussed above in order to determine which of the
variants to further examine. Also, coulumbic and van der Waals
interactions are used to determine the interaction energies of the
epitope and the variant paratopes. Also site directed mutagenesis
is used to see if predicted changes in antibody structure actually
result in the desired changes in binding characteristics.
Alternatively, changes may be made to the epitope to verify that
the models are correct or to determine general binding themes that
may be occurring between the paratope and the epitope.
[0141] As will be appreciated by one of skill in the art, while
these models will provide the guidance necessary to make the
antibodies and variants thereof of the present embodiments, it may
still be desirable to perform routine testing of the in silico
models, perhaps through in vitro studies. In addition, as will be
apparent to one of skill in the art, any modification may also have
additional side effects on the activity of the antibody. For
instance, while any alteration predicted to result in greater
binding, may induce greater binding, it may also cause other
structural changes which might reduce or alter the activity of the
antibody. The determination of whether or not this is the case is
routine in the art and can be achieved in many ways. For example,
the activity can be tested through an ELISA test. Alternatively,
the samples can be tested through the use of a surface plasmon
resonance device.
HER3 Antibodies The present invention provides antibodies that
recognize a conformational epitope of HER3. The invention is based
on the surprising finding that a class of antibodies against HER3,
block both ligand-dependent and ligand-independent HER3 signal
transduction pathways. A class of antibodies that bind to the
particular conformation epitope of HER3 is disclosed in Table 1. In
one embodiment, the antibodies inhibit both ligand-dependent and
ligand-independent HER3 signalling. In another embodiment, the
antibodies bind to HER3 and do not block HER ligand binding to the
ligand binding site (i.e. both ligand and antibody can bind HER3
concurrently).
[0142] The present invention provides antibodies that specifically
bind a HER3 protein (e.g., human and/or cynomologus HER3), said
antibodies comprising a VH domain having an amino acid sequence of
SEQ ID NO: 15, 33, 51, 69, 87, 105, 123, 141, 159, 177, 195, 213,
231, 249, 267, 285, 303, 321, 339, 357, and 375. The present
invention provides antibodies that specifically bind a HER3 protein
(e.g., human and/or cynomologus HER3), said antibodies comprising a
VL domain having an amino acid sequence of SEQ ID NO: 14, 32, 50,
68, 86, 104, 122, 140, 158, 176, 194, 212, 230, 248, 266, 284, 302,
320, 338, 356, and 374. The present invention also provides
antibodies that specifically bind to a HER3 protein (e.g., human
and/or cynomologus HER3), said antibodies comprising a VH CDR
having an amino acid sequence of any one of the VH CDRs listed in
Table 1, infra. In particular, the invention provides antibodies
that specifically bind to a HER3 protein (e.g., human and/or
cynomologus HER3), said antibodies comprising (or alternatively,
consisting of) one, two, three, four, five or more VH CDRs having
an amino acid sequence of any of the VH CDRs listed in Table 1,
infra.
[0143] Other antibodies of the invention include amino acids that
have been mutated, yet have at least 60, 70, 80, 90, 95, or 98
percent identity in the CDR regions with the CDR regions depicted
in the sequences described in Table 1. In some embodiments, it
includes mutant amino acid sequences wherein no more than 1, 2, 3,
4 or 5 amino acids have been mutated in the CDR regions when
compared with the CDR regions depicted in the sequence described
Table 1, while still maintaining their specificity for the original
antibody's epitope
[0144] Other antibodies of the invention include amino acids that
have been mutated, yet have at least 60, 70, 80, 90, 95, or 98
percent identity in the framework regions with the framework
regions depicted in the sequences described in Table 1. In some
embodiments, it includes mutant amino acid sequences wherein no
more than 1, 2, 3, 4, 5, 6, or 7 amino acids have been mutated in
the framework regions when compared with the framework regions
depicted in the sequence described Table 1, while still maintaining
their specificity for the original antibody's epitope. The present
invention also provides nucleic acid sequences that encode VH, VL,
the full length heavy chain, and the full length light chain of the
antibodies that specifically bind to a HER3 protein (e.g., human
and/or cynomologus HER3).
[0145] The HER3 antibodies of the invention bind to the
conformational epitope of HER3 comprising amino acid residues from
domain 2 and domain 4 of HER3.

[0146] Other antibodies of the invention include those where the
amino acids or nucleic acids encoding the amino acids have been
mutated, yet have at least 60, 70, 80, 90, 95, 96, 97, 98, and 99
percent identity to the sequences described in Table 1. In some
embodiments, it include mutant amino acid sequences wherein no more
than 1, 2, 3, 4 or 5 amino acids have been mutated in the variable
regions when compared with the variable regions depicted in the
sequence described in Table 1, while retaining substantially the
same therapeutic activity.
[0147] Since each of these antibodies or fragments thereof can bind
to HER3, the VH, VL, full length light chain, and full length heavy
chain sequences (amino acid sequences and the nucleotide sequences
encoding the amino acid sequences) can be "mixed and matched" to
create other HER3-binding antibodies of the invention. Such "mixed
and matched" HER3-binding antibodies can be tested using the
binding assays known in the art (e.g., ELISAs, and other assays
described in the Example section). When these chains are mixed and
matched, a VH sequence from a particular VH/VL pairing should be
replaced with a structurally similar VH sequence. Likewise a full
length heavy chain sequence from a particular full length heavy
chain/full length light chain pairing should be replaced with a
structurally similar full length heavy chain sequence. Likewise, a
VL sequence from a particular VH/VL pairing should be replaced with
a structurally similar VL sequence. Likewise a full length light
chain sequence from a particular full length heavy chain/full
length light chain pairing should be replaced with a structurally
similar full length light chain sequence. Accordingly, in one
aspect, the invention provides an isolated monoclonal antibody or
fragment thereof having: a heavy chain variable region comprising
an amino acid sequence selected from the group consisting of SEQ ID
NO: 15, 33, 51, 69, 87, 105, 123, 141, 159, 177, 195, 213, 231,
249, 267, 285, 303, 321, 339, 357, and 375; and a light chain
variable region comprising an amino acid sequence selected from the
group consisting of SEQ ID NOs: 14, 32, 50, 68, 86, 104, 122, 140,
158, 176, 194, 212, 230, 248, 266, 284, 302, 320, 338, 356, and
374; wherein the antibody specifically binds to HER3 (e.g., human
and/or cynomologus).
[0148] In another aspect, the present invention provides
HER3-binding antibodies that comprise the heavy chain and light
chain CDR1s, CDR2s and CDR3s as described in Table 1, or
combinations thereof. The amino acid sequences of the VH CDR's of
the antibodies are shown in SEQ ID NOs: 2, 8, 20, 26, 38, 44, 56,

[0171] As used herein, a human antibody comprises heavy or light
chain variable regions or full length heavy or light chains that
are "the product of" or "derived from" a particular germline
sequence if the variable regions or full length chains of the
antibody are obtained from a system that uses human germline
immunoglobulin genes. Such systems include immunizing a transgenic
mouse carrying human immunoglobulin genes with the antigen of
interest or screening a human immunoglobulin gene library displayed
on phage with the antigen of interest. A human antibody that is
"the product of" or "derived from" a human germline immunoglobulin
sequence can be identified as such by comparing the amino acid
sequence of the human antibody to the amino acid sequences of human
germline immunoglobulins and selecting the human germline
immunoglobulin sequence that is closest in sequence (i.e., greatest
% identity) to the sequence of the human antibody. A human antibody
that is "the product of" or "derived from" a particular human
germline immunoglobulin sequence may contain amino acid differences
as compared to the germline sequence, due to, for example,
naturally occurring somatic mutations or intentional introduction
of site-directed mutations. However, in the VH or VL framework
regions, a selected human antibody typically is at least 90%
identical in amino acids sequence to an amino acid sequence encoded
by a human germline immunoglobulin gene and contains amino acid
residues that identify the human antibody as being human when
compared to the germline immunoglobulin amino acid sequences of
other species (e.g., murine germline sequences). In certain cases,
a human antibody may be at least 60%, 70%, 80%, 90%, or at least
95%, or even at least 96%, 97%, 98%, or 99% identical in amino acid
sequence to the amino acid sequence encoded by the germline
immunoglobulin gene. Typically, a recombinant human antibody will
display no more than 10 amino acid differences from the amino acid
sequence encoded by the human germline immunoglobulin gene in the
VH or VL framework regions. In certain cases, the human antibody
may display no more than 5, or even no more than 4, 3, 2, or 1
amino acid difference from the amino acid sequence encoded by the
germline immunoglobulin gene. Different germlined versions using
the VH and VL germline sequences for a representative number of
HER3 antibodies is shown in Table 2, using Kabat. The CDR positions
are highlighted in boldface. The notation used in the Tables with
germlined sequences is as follows: MOR10701-VH 3-07 means MOR10701
CDR loops in framework regions of VH germline sequence 3-07
(nomenclature is according to Vbase), MOR10703-VK_L1 means CDR from
MOR10703 in germline framework regions from VK_L1, where VK is the
kappa light chain.

10 amino acids.
[0187] The antibodies disclosed herein can be derivatives of single
chain antibodies, diabodies, domain antibodies, nanobodies, and
unibodies. A "single-chain antibody" (scFv) consists of a single
polypeptide chain comprising a VL domain linked to a VH domain,
wherein VL domain and VH domain are paired to form a monovalent
molecule. Single chain antibody can be prepared according to method
known in the art (see, for example, Bird et al., (1988) Science
242:423-426 and Huston et al., (1988) Proc. Natl. Acad. Sci. USA
85:5879-5883). A "disbud" consists of two chains, each chain
comprising a heavy chain variable region connected to a light chain
variable region on the same polypeptide chain connected by a short
peptide linker, wherein the two regions on the same chain do not
pair with each other but with complementary domains on the other
chain to form a bispecific molecule. Methods of preparing diabodies
are known in the art (See, e.g., Holliger et al., (1993) Proc.
Natl. Acad. Sci. USA 90:6444-6448, and Poljak et al., (1994)
Structure 2:1121-1123). Domain antibodies (dAbs) are small
functional binding units of antibodies, corresponding to the
variable regions of either the heavy or light chains of antibodies.
Domain antibodies are well expressed in bacterial, yeast, and
mammalian cell systems. Further details of domain antibodies and
methods of production thereof are known in the art (see, for
example, U.S. Pat. Nos. 6,291,158; 6,582,915; 6,593,081; 6,172,197;
6,696,245; European Patents 0368684 & 0616640; WO05/035572,
WO04/101790, WO04/081026, WO04/058821, WO04/003019 and WO03/002609.
Nanobodies are derived from the heavy chains of an antibody. A
nanobody typically comprises a single variable domain and two
constant domains (CH2 and CH3) and retains antigen-binding capacity
of the original antibody. Nanobodies can be prepared by methods
known in the art (See e.g., U.S. Pat. Nos. 6,765,087, 6,838,254, WO
06/079372). Unibodies consist of one light chain and one heavy
chain of a IgG4 antibody. Unibodies may be made by the removal of
the hinge region of IgG4 antibodies. Further details of unibodies
and methods of preparing them may be found in WO2007/059782.
Homologous Antibodies
[0188] In yet another embodiment, the present invention provides an
antibody or fragment thereof comprising amino acid sequences that
are homologous to the sequences described in Table 1, and said
antibody binds to a HER3 protein (e.g., human and/or cynomologus
HER3), and retains the desired functional properties of those
antibodies described in Table 1.
[0189] For example, the invention provides an isolated monoclonal
antibody (or a functional fragment thereof) comprising a heavy
chain variable region and a light chain variable region, wherein
the heavy chain variable region comprises an amino acid sequence
that is at least 80%, at least 90%, or at least 95% identical to an
amino acid sequence selected from the group consisting of SEQ ID
NOs: 15, 33, 51, 69, 87, 105, 123, 141, 159, 177, 195, 213, 231,
249, 267, 285, 303, 321, 339, 357, and 375; the light chain
variable region comprises an amino acid sequence that is at least
80%, at least 90%, or at least 95% identical to an amino acid
sequence selected from the group consisting of SEQ ID NOs: 14, 32,
50, 68, 86, 104, 122, 140, 158, 176, 194, 212, 230, 248, 266, 284,
302, 320, 338, 356, and 374; the antibody binds to HER3 (e.g.,
human and/or cynomologus HER3) and neutralizes the signaling
activity of HER3, which can be measured in a phosphorylation assay
or other measure of HER signaling (e.g., phospho-HER3 assays,
phospho-Akt assays, cell proliferation, and ligand blocking assays
as described in the Examples). Also includes within the scope of
the invention are variable heavy and light chain parental
nucleotide sequences; and full length heavy and light chain
sequences optimized for expression in a mammalian cell. Other
antibodies of the invention include amino acids or nucleic acids
that have been mutated, yet have at least 60, 70, 80, 90, 95, or
98% percent identity to the sequences described above. In some
embodiments, it include mutant amino acid sequences wherein no more
than 1, 2, 3, 4 or 5 amino acids have been mutated by amino acid
deletion, insertion or substitution in the variable regions when
compared with the variable regions depicted in the sequence
described above.
[0190] In other embodiments, the VH and/or VL amino acid sequences
may be 50%, 60%, 70%, 80%, 90%, 95%, 96%, 97%, 98% or 99% identical
to the sequences set forth in Table 1. In other embodiments, the VH
and/or VL amino acid sequences may be identical except an amino
acid substitution in no more than 1, 2, 3, 4 or 5 amino acid
position. An antibody having VH and VL regions having high (i. e.,
80% or greater) identity to the VH and VL regions of the antibodies
described in Table 1 can be obtained by mutagenesis (e.g.,
site-directed or PCR-mediated mutagenesis), followed by testing of
the encoded altered antibody for retained function using the
functional assays described herein.
[0191] In other embodiments, the variable regions of heavy chain
and/or light chain nucleotide sequences may be 60%, 70%, 80%, 90%,
95%, 96%, 97%, 98% or 99% identical to the sequences set forth
above.
[0192] As used herein, "percent identity" between the two sequences
is a function of the number of identical positions shared by the
sequences (i.e., % identity equals number of identical
positions/total number of positions.times.100), taking into account
the number of gaps, and the length of each gap, which needs to be
introduced for optimal alignment of the two sequences. The
comparison of sequences and determination of percent identity
between two sequences can be accomplished using a mathematical
algorithm, as described in the non-limiting examples below.
[0193] Additionally or alternatively, the protein sequences of the
present invention can further be used as a "query sequence" to
perform a search against public databases to, for example,
identifies related sequences. For example, such searches can be
performed using the BLAST program (version 2.0) of Altschul et al.,
(1990) J. Mol. Biol. 215:403-10.
Antibodies with Conservative Modifications
[0194] In certain embodiments, an antibody of the invention has a
heavy chain variable region comprising CDR1, CDR2, and CDR3
sequences and a light chain variable region comprising CDR1, CDR2,
and CDR3 sequences, wherein one or more of these CDR sequences have
specified amino acid sequences based on the antibodies described
herein or conservative modifications thereof, and wherein the
antibodies retain the desired functional properties of the
HER3-binding antibodies of the invention.
[0195] Accordingly, the invention provides an isolated HER3
monoclonal antibody, or a fragment thereof, consisting of a heavy
chain variable region comprising CDR1, CDR2, and CDR3 sequences and
a light chain variable region comprising CDR1, CDR2, and CDR3
sequences, wherein: the heavy chain variable region CDR1 amino acid

fragment thereof specifically binds to HER3, and neutralizes HER3
activity by inhibiting a HER signaling pathway, which can be
measured in a phosphorylation assay or other measure of HER
signaling (e.g., phospho-HER3 assays, phospho-Akt assays, cell
proliferation, and ligand blocking assays as described in the
Examples).
Antibodies that Bind to the Same Epitope
[0196] The present invention provides antibodies that interacts
with (e.g., by binding, steric hindrance,
stabilizing/destabilizing, spatial distribution) the same epitope
as do the HER3-binding antibodies described in Table 1 and FIG. 7.
Additional antibodies can therefore be identified based on their
ability to cross-compete (e.g., to competitively inhibit the
binding of, in a statistically significant manner) with other
antibodies of the invention in HER3 binding assays. The ability of
a test antibody to inhibit the binding of antibodies of the present
invention to a HER3 protein (e.g., human and/or cynomologus HER3)
demonstrates that the test antibody can compete with that antibody
for binding to HER3; such an antibody may, according to
non-limiting theory, bind to the same or a related (e.g., a
structurally similar or spatially proximal) epitope on the HER3
protein as the antibody with which it competes. In a certain
embodiment, the antibody that binds to the same epitope on HER3 as
the antibodies of the present invention is a human monoclonal
antibody. Such human monoclonal antibodies can be prepared and
isolated as described herein.
[0197] In one embodiment, the antibody or fragments thereof binds
to both domain 2 and domain 4 of HER3 to hold the HER3 in an
inactive conformation which prevents exposure of an dimerization
loop present within domain 2. This prevents heterodimerizaton with
other family members, such as HER1, HER2, and HER4. The antibodies
of fragments thereof inhibit both ligand dependent and
ligand-independent HER3 signal transduction.
[0198] In another embodiment, the antibody or fragment thereof
binds to both domain 2 and domain 4 of HER3 and without blocking
the concurrent binding of a HER3 ligand such as neuregulin. While
not required to provide a theory, it is feasible that the antibody
or fragment thereof binding to both domain 2 and domain 4 of HER3,
holds HER3 in an inactive conformation without blocking the ligand
binding site on HER3. Thus a HER3 ligand (e.g., neuregulin) is able
to bind to HER3 at the same time as the antibody or fragment
thereof.
[0199] The antibodies of the invention or fragments thereof inhibit
both ligand dependent and independent activation of HER3 without
preventing ligand binding. This is considered advantageous for the
following reasons:
[0200] (i) The therapeutic antibody would have clinical utility in
a broad spectrum of tumors than an antibody which targeted a single
mechanism of HER3 activation (i.e. ligand dependent or ligand
independent) since distinct tumor types are driven by each
mechanism.
[0201] (ii) The therapeutic antibody would be efficacious in tumor
types where both mechanisms of HER3 activation are simultaneously
involved. An antibody targeting a single mechanism of HER3
activation (i.e. ligand dependent or ligand independent) would
display little or no efficacy in these tumor types
[0202] (iii) The efficacy of an antibody which inhibits ligand
dependent activation of HER3 without preventing ligand binding
would be less likely to be adversely affected by increasing
concentrations of ligand. This would translate to either increased
efficacy in a tumor type driven by very high concentrations of HER3
ligand or a reduced drug resistance liability where resistance is
mediated by up-regulation of HER3 ligands.
[0203] (iv) An antibody which inhibits HER3 activation by
stabilizing the inactive form would be less prone to drug
resistance driven by alternative mechanisms of HER3 activation.
[0204] Consequently, the antibodies of the invention may be used to
treat conditions where existing therapeutic antibodies are
clinically ineffective.
Engineered and Modified Antibodies
[0205] An antibody of the invention further can be prepared using
an antibody having one or more of the VH and/or VL sequences shown
herein as starting material to engineer a modified antibody, which
modified antibody may have altered properties from the starting
antibody. An antibody can be engineered by modifying one or more
residues within one or both variable regions (i. e., VH and/or VL),
for example within one or more CDR regions and/or within one or
more framework regions. Additionally or alternatively, an antibody
can be engineered by modifying residues within the constant
region(s), for example to alter the effector function(s) of the
antibody.
[0206] One type of variable region engineering that can be
performed is CDR grafting. Antibodies interact with target antigens
predominantly through amino acid residues that are located in the
six heavy and light chain complementarity determining regions
(CDRs). For this reason, the amino acid sequences within CDRs are
more diverse between individual antibodies than sequences outside
of CDRs. Because CDR sequences are responsible for most
antibody-antigen interactions, it is possible to express
recombinant antibodies that mimic the properties of specific
naturally occurring antibodies by constructing expression vectors
that include CDR sequences from the specific naturally occurring
antibody grafted onto framework sequences from a different antibody
with different properties (see, e.g., Riechmann et al., (1998)
Nature 332:323-327; Jones et al., (1986) Nature 321:522-525; Queen
et al., (1989) Proc. Natl. Acad., U.S.A. 86:10029-10033; U.S. Pat.

5,693,762 and 6,180,370 to Queen et al.)
[0207] Accordingly, another embodiment of the invention pertains to

an amino acid sequence selected from the group consisting of SEQ ID
NOs: 4, 10, 22, 28, 40, 46, 58, 64, 76, 82, 94, 100, 112, 118, 130,
136, 148, 154, 166, 172, 184, 190, 202, 208, 220, 226, 238, 244,
256, 262, 274, 280, 292, 298, 310, 316, 328, 334, 346, 352, 364,
and 370, respectively; and a light chain variable region having
CDR1 sequences having an amino acid sequence selected from the
group consisting of SEQ ID NOs: 5, 11, 23, 29, 41, 47, 59, 65, 77,
83, 95, 101, 113, 119, 131, 137, 149, 155, 167, 173, 185, 191, 203,

329, 335, 347, 353, 365, and 371; CDR2 sequences having an amino
acid sequence selected from the group consisting of SEQ ID NOs: 6,
12, 24, 30, 42, 48, 60, 66, 78, 84, 96, 102, 114, 120, 132, 138,
150, 156, 168, 174, 186, 192, 204, 210, 222, 228, 240, 246, 258,
264, 276, 282, 294, 300, 312, 318, 330, 336, 348, 354, 366, and
372; and CDR3 sequences consisting of an amino acid sequence
selected from the group consisting of SEQ ID NOs: 7, 13, 25, 31,
43, 49, 61, 67, 79, 85, 97, 103, 115, 121, 135, 139, 151, 157, 169,

295, 301, 313, 319, 331, 337, 349, 355, 367, and 373, respectively.
Thus, such antibodies contain the VH and VL CDR sequences of
monoclonal antibodies, yet may contain different framework
sequences from these antibodies. Such framework sequences can be
obtained from public DNA databases or published references that
include germline antibody gene sequences. For example, germline DNA
sequences for human heavy and light chain variable region genes can
be found in the "Vase" human germline sequence database (available
on the Internet at www.mrc-cpe.cam.ac.uk/vbase), as well as in
Kabat et al., (1991) Sequences of Proteins of Immunological
Interest, Fifth Edition, U.S. Department of Health and Human
Services, NIH Publication No. 91-3242; Chothia et al., (1987) J.
Mol. Biol. 196:901-917; Chothia et al., (1989) Nature 342:877-883;
and Al-Lazikani et al., (1997) J. Mol. Biol. 273:927-948; Tomlinson
et al., (1992) J. fol. Biol. 227:776-798; and Cox et al., (1994)
Eur. J Immunol. 24:827-836; the contents of each of which are
expressly incorporated herein by reference.
[0208] An example of framework sequences for use in the antibodies
of the invention are those that are structurally similar to the
framework sequences used by selected antibodies of the invention,
e.g., consensus sequences and/or framework sequences used by
monoclonal antibodies of the invention. The VH CDR1, 2 and 3
sequences, and the VL CDR1, 2 and 3 sequences, can be grafted onto
framework regions that have the identical sequence as that found in
the germline immunoglobulin gene from which the framework sequence
derive, or the CDR sequences can be grafted onto framework regions
that contain one or more mutations as compared to the germline
sequences. For example, it has been found that in certain instances
it is beneficial to mutate residues within the framework regions to
maintain or enhance the antigen binding ability of the antibody
(see e.g., U.S. Pat. Nos. 5,530,101; 5,585,089; 5,693,762 and
6,180,370 to Queen et al).
[0209] Another type of variable region modification is to mutate
amino acid residues within the VH and/or VL CDR1, CDR2 and/or CDR3
regions to thereby improve one or more binding properties (e.g.,
affinity) of the antibody of interest, known as "affinity
maturation." Site-directed mutagenesis or PCR-mediated mutagenesis
can be performed to introduce the mutation(s) and the effect on
antibody binding, or other functional property of interest, can be
evaluated in in vitro or in vivo assays as described herein and
provided in the Examples. Conservative modifications (as discussed
above) can be introduced. The mutations may be amino acid
substitutions, additions or deletions. Moreover, typically no more
than one, two, three, four or five residues within a CDR region are
altered.
[0210] Accordingly, in another embodiment, the invention provides
isolated HER3 binding monoclonal antibodies, or fragment thereof,

Grafting Antibody Fragments into Alternative Frameworks or
Scaffolds
[0211] A wide variety of antibody/immunoglobulin frameworks or
scaffolds can be employed so long as the resulting polypeptide
includes at least one binding region which specifically binds to
HER3. Such frameworks or scaffolds include the 5 main idiotypes of
human immunoglobulins, or fragments thereof, and include
immunoglobulins of other animal species, preferably having
humanized aspects. Novel frameworks, scaffolds and fragments
continue to be discovered and developed by those skilled in the
art.
[0212] In one aspect, the invention pertains to generating
non-immunoglobulin based antibodies using non-immunoglobulin
scaffolds onto which CDRs of the invention can be grafted. Known or
future non-immunoglobulin frameworks and scaffolds may be employed,
as long as they comprise a binding region specific for the target
HER3 protein (e.g., human and/or cynomologus HER3). Known
non-immunoglobulin frameworks or scaffolds include, but are not
limited to, fibronectin (Compound Therapeutics, Inc., Waltham,
Mass.), ankyrin (Molecular Partners AG, Zurich, Switzerland),
domain antibodies (Domantis, Ltd., Cambridge, Mass., and Ablynx nv,
Zwijnaarde, Belgium), lipocalin (Pieris Proteolab AG, Freising,
Germany), small modular immuno-pharmaceuticals (Trubion
Pharmaceuticals Inc., Seattle, Wash.), maxybodies (Avidia, Inc.,
Mountain View, Calif.), Protein A (Affibody AG, Sweden), and
affilin (gamma-crystallin or ubiquitin) (Scil Proteins GmbH, Halle,
Germany).
[0213] The fibronectin scaffolds are based on fibronectin type III
domain (e.g., the tenth module of the fibronectin type III (.sup.10
Fn3 domain)). The fibronectin type III domain has 7 or 8 beta
strands which are distributed between two beta sheets, which
themselves pack against each other to form the core of the protein,
and further containing loops (analogous to CDRs) which connect the
beta strands to each other and are solvent exposed. There are at
least three such loops at each edge of the beta sheet sandwich,
where the edge is the boundary of the protein perpendicular to the
direction of the beta strands (see U.S. Pat. No. 6,818,418). These
fibronectin-based scaffolds are not an immunoglobulin, although the
overall fold is closely related to that of the smallest functional
antibody fragment, the variable region of the heavy chain, which
comprises the entire antigen recognition unit in camel and llama
IgG. Because of this structure, the non-immunoglobulin antibody
mimics antigen binding properties that are similar in nature and
affinity to those of antibodies. These scaffolds can be used in a
loop randomization and shuffling strategy in vitro that is similar
to the process of affinity maturation of antibodies in vivo. These
fibronectin-based molecules can be used as scaffolds where the loop
regions of the molecule can be replaced with CDRs of the invention
using standard cloning techniques.
[0214] The ankyrin technology is based on using proteins with
ankyrin derived repeat modules as scaffolds for bearing variable
regions which can be used for binding to different targets. The
ankyrin repeat module is a 33 amino acid polypeptide consisting of
two anti-parallel .alpha.-helices and a .beta.-turn. Binding of the
variable regions is mostly optimized by using ribosome display.
[0215] Avimers are derived from natural A-domain containing protein
such as HER3. These domains are used by nature for protein-protein
interactions and in human over 250 proteins are structurally based
on A-domains. Avimers consist of a number of different "A-domain"
monomers (2-10) linked via amino acid linkers. Avimers can be
created that can bind to the target antigen using the methodology
described in, for example, U.S. Patent Application Publication Nos.
20040175756; 20050053973; 20050048512; and 20060008844.
[0216] Affibody affinity ligands are small, simple proteins
composed of a three-helix bundle based on the scaffold of one of
the IgG-binding domains of Protein A. Protein A is a surface
protein from the bacterium Staphylococcus aureus. This scaffold
domain consists of 58 amino acids, 13 of which are randomized to
generate affibody libraries with a large number of ligand variants
(See e.g., U.S. Pat. No. 5,831,012). Affibody molecules mimic
antibodies, they have a molecular weight of 6 kDa, compared to the
molecular weight of antibodies, which is 150 kDa. In spite of its
small size, the binding site of affibody molecules is similar to
that of an antibody.
[0217] Anticalins are products developed by the company Pieris
ProteoLab AG. They are derived from lipocalins, a widespread group
of small and robust proteins that are usually involved in the
physiological transport or storage of chemically sensitive or
insoluble compounds. Several natural lipocalins occur in human
tissues or body liquids. The protein architecture is reminiscent of
immunoglobulins, with hypervariable loops on top of a rigid
framework. However, in contrast with antibodies or their
recombinant fragments, lipocalins are composed of a single
polypeptide chain with 160 to 180 amino acid residues, being just
marginally bigger than a single immunoglobulin domain. The set of
four loops, which makes up the binding pocket, shows pronounced
structural plasticity and tolerates a variety of side chains. The
binding site can thus be reshaped in a proprietary process in order
to recognize prescribed target molecules of different shape with
high affinity and specificity. One protein of lipocalin family, the
bilin-binding protein (BBP) of Pieris Brassicae has been used to
develop anticalins by mutagenizing the set of four loops. One
example of a patent application describing anticalins is in PCT
Publication No. WO 199916873.
[0218] Affilin molecules are small non-immunoglobulin proteins
which are designed for specific affinities towards proteins and
small molecules. New affilin molecules can be very quickly selected
from two libraries, each of which is based on a different human
derived scaffold protein. Affilin molecules do not show any
structural homology to immunoglobulin proteins. Currently, two
affilin scaffolds are employed, one of which is gamma crystalline,
a human structural eye lens protein and the other is "ubiquitin"
superfamily proteins. Both human scaffolds are very small, show
high temperature stability and are almost resistant to pH changes
and denaturing agents. This high stability is mainly due to the
expanded beta sheet structure of the proteins. Examples of gamma
crystalline derived proteins are described in WO200104144 and
examples of "ubiquitin-like" proteins are described in
WO2004106368.
[0219] Protein epitope mimetics (PEM) are medium-sized, cyclic,
peptide-like molecules (MW 1-2 kDa) mimicking beta-hairpin
secondary structures of proteins, the major secondary structure
involved in protein-protein interactions.
[0220] In some embodiments, the Fabs are converted to silent IgG1
format by changing the Fc region. For example, antibodies in Table
1 can be converted to IgG format.
Human or Humanized Antibodies
[0221] The present invention provides fully human antibodies that
specifically bind to a HER3 protein (e.g., human and/or
cynomologus/mouse/rat HER3). Compared to the chimeric or humanized
antibodies, the human HER3-binding antibodies of the invention have
further reduced antigenicity when administered to human
subjects.
[0222] The human HER3-binding antibodies can be generated using
methods that are known in the art. For example, the humaneering
technology used to converting non-human antibodies into engineered
human antibodies. U.S. Patent Publication No. 20050008625 describes
an in vivo method for replacing a nonhuman antibody variable region
with a human variable region in an antibody while maintaining the
same or providing better binding characteristics relative to that
of the nonhuman antibody. The method relies on epitope guided
replacement of variable regions of a non-human reference antibody
with a fully human antibody. The resulting human antibody is
generally unrelated structurally to the reference nonhuman
antibody, but binds to the same epitope on the same antigen as the
reference antibody. Briefly, the serial epitope-guided
complementarity replacement approach is enabled by setting up a
competition in cells between a "competitor" and a library of
diverse hybrids of the reference antibody ("test antibodies") for
binding to limiting amounts of antigen in the presence of a
reporter system which responds to the binding of test antibody to
antigen. The competitor can be the reference antibody or derivative
thereof such as a single-chain Fv fragment. The competitor can also
be a natural or artificial ligand of the antigen which binds to the
same epitope as the reference antibody. The only requirements of
the competitor are that it binds to the same epitope as the
reference antibody, and that it competes with the reference
antibody for antigen binding. The test antibodies have one
antigen-binding V-region in common from the nonhuman reference
antibody, and the other V-region selected at random from a diverse
source such as a repertoire library of human antibodies. The common
V-region from the reference antibody serves as a guide, positioning
the test antibodies on the same epitope on the antigen, and in the
same orientation, so that selection is biased toward the highest
antigen-binding fidelity to the reference antibody.
[0223] Many types of reporter system can be used to detect desired
interactions between test antibodies and antigen. For example,
complementing reporter fragments may be linked to antigen and test
antibody, respectively, so that reporter activation by fragment
complementation only occurs when the test antibody binds to the
antigen. When the test antibody- and antigen-reporter fragment
fusions are co-expressed with a competitor, reporter activation
becomes dependent on the ability of the test antibody to compete
with the competitor, which is proportional to the affinity of the
test antibody for the antigen. Other reporter systems that can be
used include the reactivator of an auto-inhibited reporter
reactivation system (RAIR) as disclosed in U.S. patent application
Ser. No. 10/208,730 (Publication No. 20030198971), or competitive
activation system disclosed in U.S. patent application Ser. No.
10/076,845 (Publication No. 20030157579).
[0224] With the serial epitope-guided complementarity replacement
system, selection is made to identify cells expresses a single test
antibody along with the competitor, antigen, and reporter
components. In these cells, each test antibody competes one-on-one
with the competitor for binding to a limiting amount of antigen.
Activity of the reporter is proportional to the amount of antigen
bound to the test antibody, which in turn is proportional to the
affinity of the test antibody for the antigen and the stability of
the test antibody. Test antibodies are initially selected on the
basis of their activity relative to that of the reference antibody
when expressed as the test antibody. The result of the first round
of selection is a set of "hybrid" antibodies, each of which is
comprised of the same non-human V-region from the reference
antibody and a human V-region from the library, and each of which
binds to the same epitope on the antigen as the reference antibody.
One of more of the hybrid antibodies selected in the first round
will have an affinity for the antigen comparable to or higher than
that of the reference antibody.
[0225] In the second V-region replacement step, the human V-regions
selected in the first step are used as guide for the selection of
human replacements for the remaining non-human reference antibody
V-region with a diverse library of cognate human V-regions. The
hybrid antibodies selected in the first round may also be used as
competitors for the second round of selection. The result of the
second round of selection is a set of fully human antibodies which
differ structurally from the reference antibody, but which compete
with the reference antibody for binding to the same antigen. Some
of the selected human antibodies bind to the same epitope on the
same antigen as the reference antibody. Among these selected human
antibodies, one or more binds to the same epitope with an affinity
which is comparable to or higher than that of the reference
antibody.
[0226] Using one of the mouse or chimeric HER3-binding antibodies
described above as the reference antibody, this method can be
readily employed to generate human antibodies that bind to human
HER3 with the same binding specificity and the same or better
binding affinity. In addition, such human HER3-binding antibodies
can also be commercially obtained from companies which customarily
produce human antibodies, e.g., KaloBios, Inc. (Mountain View,
Calif.).
Camelid Antibodies
[0227] Antibody proteins obtained from members of the camel and
dromedary (Camelus bactrianus and Calelus dromaderius) family
including new world members such as llama species (Lama paccos,
Lama glama and Lama vicugna) have been characterized with respect
to size, structural complexity and antigenicity for human subjects.
Certain IgG antibodies from this family of mammals as found in
nature lack light chains, and are thus structurally distinct from
the typical four chain quaternary structure having two heavy and
two light chains, for antibodies from other animals. See
PCT/EP93/02214 (WO 94/04678 published 3 Mar. 1994).
[0228] A region of the camelid antibody which is the small single
variable domain identified as VHH can be obtained by genetic
engineering to yield a small protein having high affinity for a
target, resulting in a low molecular weight antibody-derived
protein known as a "camelid nanobody". See U.S. Pat. No. 5,759,808
issued Jun. 2, 1998; see also Stijlemans et al., (2004) J Biol Chem
279:1256-1261; Dumoulin et al., (2003) Nature 424:783-788;
Pleschberger et al., (2003) Bioconjugate Chem 14:440-448;
Cortez-Retamozo et al., (2002) Int J Cancer 89:456-62; and
Lauwereys et al., (1998) EMBO J 17:3512-3520. Engineered libraries
of camelid antibodies and antibody fragments are commercially
available, for example, from Ablynx, Ghent, Belgium. (e.g.,
US20060115470; Domantis (US20070065440, US20090148434). As with
other antibodies of non-human origin, an amino acid sequence of a
camelid antibody can be altered recombinantly to obtain a sequence
that more closely resembles a human sequence, i.e., the nanobody
can be "humanized". Thus the natural low antigenicity of camelid
antibodies to humans can be further reduced.
[0229] The camelid nanobody has a molecular weight approximately
one-tenth that of a human IgG molecule, and the protein has a
physical diameter of only a few nanometers. One consequence of the
small size is the ability of camelid nanobodies to bind to
antigenic sites that are functionally invisible to larger antibody
proteins, i.e., camelid nanobodies are useful as reagents detect
antigens that are otherwise cryptic using classical immunological
techniques, and as possible therapeutic agents. Thus yet another
consequence of small size is that a camelid nanobody can inhibit as
a result of binding to a specific site in a groove or narrow cleft
of a target protein, and hence can serve in a capacity that more
closely resembles the function of a classical low molecular weight
drug than that of a classical antibody.
[0230] The low molecular weight and compact size further result in
camelid nanobodies being extremely thermostable, stable to extreme
pH and to proteolytic digestion, and poorly antigenic. Another
consequence is that camelid nanobodies readily move from the
circulatory system into tissues, and even cross the blood-brain
barrier and can treat disorders that affect nervous tissue.
Nanobodies can further facilitated drug transport across the blood
brain barrier. See U.S. patent application 20040161738 published
Aug. 19, 2004. These features combined with the low antigenicity to
humans indicate great therapeutic potential. Further, these
molecules can be fully expressed in prokaryotic cells such as E.
coli and are expressed as fusion proteins with bacteriophage and
are functional.
[0231] Accordingly, a feature of the present invention is a camelid
antibody or nanobody having high affinity for HER3. In certain
embodiments herein, the camelid antibody or nanobody is naturally
produced in the camelid animal, i.e., is produced by the camelid
following immunization with HER3 or a peptide fragment thereof,
using techniques described herein for other antibodies.
Alternatively, the HER3-binding camelid nanobody is engineered,
i.e., produced by selection for example from a library of phage
displaying appropriately mutagenized camelid nanobody proteins
using panning procedures with HER3 as a target as described in the
examples herein. Engineered nanobodies can further be customized by
genetic engineering to have a half life in a recipient subject of
from 45 minutes to two weeks. In a specific embodiment, the camelid
antibody or nanobody is obtained by grafting the CDRs sequences of
the heavy or light chain of the human antibodies of the invention
into nanobody or single domain antibody framework sequences, as
described for example in PCT/EP93/02214. In one embodiment, the
camelid antibody or nanobody binds to at least one of the following
HER3 residues: Asn266, Lys267, Leu268, Thr269, Gln271, Glu273,
Pro274, Asn275, Pro276, His277, Asn315, Asp571, Pro583, His584,
Ala596, Lys597 (residues of SEQ ID NO: 1). In one embodiment, the
camelid antibody or nanobody binds to at least one of the following
HER3 residues: Tyr265, Lys267, Leu268, Phe270, Gly582, Pro583,
Lys597, Ile600, Lys602, Glu609, Arg611, Pro612, Cys613, His614,
Glu615 (residues of SEQ ID NO: 1).
Bispecific Molecules and Multivalent Antibodies
[0232] In another aspect, the present invention features
biparatopic, bispecific or multispecific molecules comprising an
HER3-binding antibody, or a fragment thereof, of the invention. An
antibody of the invention, or fragments thereof, can be derivatized
or linked to another functional molecule, e.g., another peptide or
protein (e.g., another antibody or ligand for a receptor) to
generate a bispecific molecule that binds to at least two different
binding sites or target molecules. The antibody of the invention
may in fact be derivatized or linked to more than one other
functional molecule to generate biparatopic or multi-specific
molecules that bind to more than two different binding sites and/or
target molecules; such biparatopic or multi-specific molecules. To
create a bispecific molecule of the invention, an antibody of the
invention can be functionally linked (e.g., by chemical coupling,
genetic fusion, non-covalent association or otherwise) to one or
more other binding molecules, such as another antibody, antibody
fragment, peptide or binding mimetic, such that a bispecific
molecule results.
[0233] Further clinical benefits may be provided by the binding of
two or more antigens within one antibody (Coloma et al., (1997);
Merchant et al., (1998); Alt et al., (1999); Zuo et al., (2000); Lu
et al., (2004); Lu et al., (2005); Marvin et al., (2005); Marvin et
al., (2006); Shen et al., (2007); Wu et al., (2007); Dimasi et al.,
(2009); Michaelson et al., (2009)). (Morrison et al., (1997) Nature
Biotech. 15:159-163; Alt et al. (1999) FEBS Letters 454:90-94; Zuo
et al., (2000) Protein Engineering 13:361-367; Lu et al., (2004)

al., (2005) Acta Pharmacologica Sinica 26:649-658; Marvin et al.,

Immun Methods 218:65-74; Wu et al., (2007) Nat Biotechnol.

Michaelson et al., (2009) mAbs 1:128-141.
[0234] The bispecific molecules of the present invention can be
prepared by conjugating the constituent binding specificities,
using methods known in the art. For example, each binding
specificity of the bispecific molecule can be generated separately
and then conjugated to one another. When the binding specificities
are proteins or peptides, a variety of coupling or cross-linking
agents can be used for covalent conjugation. Examples of
cross-linking agents include protein A, carbodiimide,
N-succinimidyl-S-acetyl-thioacetate (SATA),
5,5'-dithiobis(2-nitrobenzoic acid) (DTNB), o-phenylenedimaleimide
(oPDM), N-succinimidyl-3-(2-pyridyldithio)propionate (SPDP), and
sulfosuccinimidyl 4-(N-maleimidomethyl) cyclohaxane-1-carboxylate
(sulfo-SMCC) (see e.g., Karpovsky et al., (1984) J. Exp. Med.
160:1686; Liu et al., (1985) Proc. Natl. Acad. Sci. USA 82:8648).
Other methods include those described in Paulus (1985) Behring Ins.
Mitt. No. 78:118-132; Brennan et al., (1985) Science 229:81-83),
and Glennie et al., (1987) J. Immunol. 139: 2367-2375). Conjugating
agents are SATA and sulfo-SMCC, both available from Pierce Chemical
Co. (Rockford, Ill.).
[0235] When the binding specificities are antibodies, they can be
conjugated by sulfhydryl bonding of the C-terminus hinge regions of
the two heavy chains. In a particularly embodiment, the hinge
region is modified to contain an odd number of sulfhydryl residues,
for example one, prior to conjugation.
[0236] Alternatively, both binding specificities can be encoded in
the same vector and expressed and assembled in the same host cell.
This method is particularly useful where the bispecific molecule is
a mAb.times.mAb, mAb.times.Fab, Fab.times.F(ab').sub.2 or ligand x
Fab fusion protein. A bispecific molecule of the invention can be a
single chain molecule comprising one single chain antibody and a
binding determinant, or a single chain bispecific molecule
comprising two binding determinants. Bispecific molecules may
comprise at least two single chain molecules. Methods for preparing
bispecific molecules are described for example in U.S. Pat. Nos.
5,260,203; 5,455,030; 4,881,175; 5,132,405; 5,091,513; 5,476,786;
5,013,653; 5,258,498; and 5,482,858.
[0237] Binding of the bispecific molecules to their specific
targets can be confirmed by, for example, enzyme-linked
immunosorbent assay (ELISA), radioimmunoassay (REA), FACS analysis,
bioassay (e.g., growth inhibition), or Western Blot assay. Each of
these assays generally detects the presence of protein-antibody
complexes of particular interest by employing a labeled reagent
(e.g., an antibody) specific for the complex of interest.
[0238] In another aspect, the present invention provides
multivalent compounds comprising at least two identical or
different fragments of the antibodies of the invention binding to
HER3. The antibody fragments can be linked together via protein
fusion or covalent or non covalent linkage. Tetravalent compounds
can be obtained for example by cross-linking antibodies of the
antibodies of the invention with an antibody that binds to the
constant regions of the antibodies of the invention, for example
the Fc or hinge region. Trimerizing domain are described for
example in Borean patent EP 1012280B1. Pentamerizing modules are
described for example in PCT/EP97/05897.
[0239] In one embodiment, a biparatopic/bispecific binds to amino
acid residues within domain 2 and domain 4 of HER3.
[0240] In another embodiment, the invention pertains to dual
function antibodies in which a single monoclonal antibody has been
modified such that the antigen binding site binds to more than one
antigen, such as a dual function antibody which binds both HER3 and
another antigen (e.g., HER1, HER2, and HER4). In another
embodiment, the invention pertains to a dual function antibody that
targets antigens having the same conformation, for example an
antigen that has the same conformation of HER3 in the "closed" or
"inactive" state. Examples of antigens with the same conformation
of HER3 in the "closed" or "inactive" state include, but are not
limited to, HER1 and HER4. Thus, a dual function antibody may bind
to both HER3 and HER1; HER3 and HER4, or HER1 and HER4. The dual
binding specificity of the dual function antibody may further
translate into dual activity, or inhibition of activity. (See e.g.,
Jenny Bostrom et al., (2009) Science: 323; 1610-1614).
Antibodies with Extended Half Life
[0241] The present invention provides for antibodies that
specifically bind to HER3 protein which have an extended half-life
in vivo.
[0242] Many factors may affect a protein's half life in vivo. For
examples, kidney filtration, metabolism in the liver, degradation
by proteolytic enzymes (proteases), and immunogenic responses
(e.g., protein neutralization by antibodies and uptake by
macrophages and dentritic cells). A variety of strategies can be
used to extend the half life of the antibodies of the present
invention. For example, by chemical linkage to polyethyleneglycol
(PEG), reCODE PEG, antibody scaffold, polysialic acid (PSA),
hydroxyethyl starch (HES), albumin-binding ligands, and
carbohydrate shields; by genetic fusion to proteins binding to
serum proteins, such as albumin, IgG, FcRn, and transferring; by
coupling (genetically or chemically) to other binding moieties that
bind to serum proteins, such as nanobodies, Fabs, DARPins, avimers,
affibodies, and anticalins; by genetic fusion to rPEG, albumin,
domain of albumin, albumin-binding proteins, and Fc; or by
incorporation into nanocarriers, slow release formulations, or
medical devices.
[0243] To prolong the serum circulation of antibodies in vivo,
inert polymer molecules such as high molecular weight PEG can be
attached to the antibodies or a fragment thereof with or without a
multifunctional linker either through site-specific conjugation of
the PEG to the N- or C-terminus of the antibodies or via
epsilon-amino groups present on lysine residues. To pegylate an
antibody, the antibody, or fragment thereof, typically is reacted
with polyethylene glycol (PEG), such as a reactive ester or
aldehyde derivative of PEG, under conditions in which one or more
PEG groups become attached to the antibody or antibody fragment.
The pegylation can be carried out by an acylation reaction or an
alkylation reaction with a reactive PEG molecule (or an analogous
reactive water-soluble polymer). As used herein, the term
"polyethylene glycol" is intended to encompass any of the forms of
PEG that have been used to derivatize other proteins, such as mono
(C1-C10) alkoxy- or aryloxy-polyethylene glycol or polyethylene
glycol-maleimide. In certain embodiments, the antibody to be
pegylated is an aglycosylated antibody. Linear or branched polymer
derivatization that results in minimal loss of biological activity
will be used. The degree of conjugation can be closely monitored by
SDS-PAGE and mass spectrometry to ensure proper conjugation of PEG
molecules to the antibodies. Unreacted PEG can be separated from
antibody-PEG conjugates by size-exclusion or by ion-exchange
chromatography. PEG-derivatized antibodies can be tested for
binding activity as well as for in vivo efficacy using methods
well-known to those of skill in the art, for example, by
immunoassays described herein. Methods for pegylating proteins are
known in the art and can be applied to the antibodies of the
invention. See for example, EP 0 154 316 by Nishimura et al. and EP
0 401 384 by Ishikawa et al.
[0244] Other modified pegylation technologies include
reconstituting chemically orthogonal directed engineering
technology (ReCODE PEG), which incorporates chemically specified
side chains into biosynthetic proteins via a reconstituted system
that includes tRNA synthetase and tRNA. This technology enables
incorporation of more than 30 new amino acids into biosynthetic
proteins in E. coli, yeast, and mammalian cells. The tRNA
incorporates a nonnative amino acid any place an amber codon is
positioned, converting the amber from a stop codon to one that
signals incorporation of the chemically specified amino acid.
[0245] Recombinant pegylation technology (rPEG) can also be used
for serum half-life extension. This technology involves genetically
fusing a 300-600 amino acid unstructured protein tail to an
existing pharmaceutical protein. Because the apparent molecular
weight of such an unstructured protein chain is about 15-fold
larger than its actual molecular weight, the serum half-life of the
protein is greatly increased. In contrast to traditional
PEGylation, which requires chemical conjugation and repurification,
the manufacturing process is greatly simplified and the product is
homogeneous.
[0246] Polysialytion is another technology, which uses the natural
polymer polysialic acid (PSA) to prolong the active life and
improve the stability of therapeutic peptides and proteins. PSA is
a polymer of sialic acid (a sugar). When used for protein and
therapeutic peptide drug delivery, polysialic acid provides a
protective microenvironment on conjugation. This increases the
active life of the therapeutic protein in the circulation and
prevents it from being recognized by the immune system. The PSA
polymer is naturally found in the human body. It was adopted by
certain bacteria which evolved over millions of years to coat their
walls with it. These naturally polysialylated bacteria were then
able, by virtue of molecular mimicry, to foil the body's defense
system. PSA, nature's ultimate stealth technology, can be easily
produced from such bacteria in large quantities and with
predetermined physical characteristics. Bacterial PSA is completely
non-immunogenic, even when coupled to proteins, as it is chemically
identical to PSA in the human body.
[0247] Another technology include the use of hydroxyethyl starch
("HES") derivatives linked to antibodies. HES is a modified natural
polymer derived from waxy maize starch and can be metabolized by
the body's enzymes. HES solutions are usually administered to
substitute deficient blood volume and to improve the rheological
properties of the blood. Hesylation of an antibody enables the
prolongation of the circulation half-life by increasing the
stability of the molecule, as well as by reducing renal clearance,
resulting in an increased biological activity. By varying different
parameters, such as the molecular weight of HES, a wide range of
HES antibody conjugates can be customized.
[0248] Antibodies having an increased half-life in vivo can also be
generated introducing one or more amino acid modifications (i.e.,
substitutions, insertions or deletions) into an IgG constant
domain, or FcRn binding fragment thereof (preferably a Fc or hinge
Fc domain fragment). See, e.g., International Publication No. WO
98/23289; International Publication No. WO 97/34631; and U.S. Pat.
No. 6,277,375.
[0249] Further, antibodies can be conjugated to albumin in order to
make the antibody or antibody fragment more stable in vivo or have
a longer half life in vivo. The techniques are well-known in the
art, see, e.g., International Publication Nos. WO 93/15199, WO
93/15200, and WO 01/77137; and European Patent No. EP 413,622.
[0250] The HER3 antibody or a fragment thereof may also be fused to
one or more human serum albumin (HSA) polypeptides, or a portion
thereof. HSA, a protein of 585 amino acids in its mature form, is
responsible for a significant proportion of the osmotic pressure of
serum and also functions as a carrier of endogenous and exogenous
ligands. The role of albumin as a carrier molecule and its inert
nature are desirable properties for use as a carrier and
transporter of polypeptides in vivo. The use of albumin as a
component of an albumin fusion protein as a carrier for various
proteins has been suggested in WO 93/15199, WO 93/15200, and EP 413
622. The use of N-terminal fragments of HSA for fusions to
polypeptides has also been proposed (EP 399 666). Accordingly, by
genetically or chemically fusing or conjugating the antibodies or
fragments thereof to albumin, can stabilize or extend the
shelf-life, and/or to retain the molecule's activity for extended
periods of time in solution, in vitro and/or in vivo.
[0251] Fusion of albumin to another protein may be achieved by
genetic manipulation, such that the DNA coding for HSA, or a
fragment thereof, is joined to the DNA coding for the protein. A
suitable host is then transformed or transfected with the fused
nucleotide sequences, so arranged on a suitable plasmid as to
express a fusion polypeptide. The expression may be effected in
vitro from, for example, prokaryotic or eukaryotic cells, or in
vivo e.g. from a transgenic organism. Additional methods pertaining
to HSA fusions can be found, for example, in WO 2001077137 and WO
200306007, incorporated herein by reference. In a specific
embodiment, the expression of the fusion protein is performed in
mammalian cell lines, for example, CHO cell lines. Altered
differential binding of an antibody to a receptor at low or high
pHs is also contemplated to be within the scope of the invention.
For example, the affinity of an antibody may be modified such that
it remains bound to it's receptor at a low pH, e.g., the low pH
within a lyzozome, by modifying the antibody to include additional
amino acids such as a histine in a CDR of the antibody (See e.g.,
Tomoyuki Igawa et al. (2010) Nature Biotechnology; 28,
1203-1207).
Antibody Conjugates
[0252] The present invention provides antibodies or fragments
thereof that specifically bind to a HER3 protein recombinantly
fused or chemically conjugated (including both covalent and
non-covalent conjugations) to a heterologous protein or polypeptide
(or fragment thereof, preferably to a polypeptide of at least 10,
at least 20, at least 30, at least 40, at least 50, at least 60, at
least 70, at least 80, at least 90 or at least 100 amino acids) to
generate fusion proteins. In particular, the invention provides
fusion proteins comprising an antibody fragment described herein
(e.g., a Fab fragment, Fd fragment, Fv fragment, F(ab)2 fragment, a
VH domain, a VH CDR, a VL domain or a VL CDR) and a heterologous
protein, polypeptide, or peptide. Methods for fusing or conjugating
proteins, polypeptides, or peptides to an antibody or an antibody
fragment are known in the art. See, e.g., U.S. Pat. Nos. 5,336,603,
5,622,929, 5,359,046, 5,349,053, 5,447,851, and 5,112,946; European
Patent Nos. EP 307,434 and EP 367,166; International Publication
Nos. WO 96/04388 and WO 91/06570; Ashkenazi et al., (1991) Proc.
Natl. Acad. Sci. USA 88:10535-10539; Zheng et al., (1995) J.
Immunol. 154:5590-5600; and Vil et al., (1992) Proc. Natl. Acad.
Sci. USA 89:11337-11341.
[0253] Additional fusion proteins may be generated through the
techniques of gene-shuffling, motif-shuffling, exon-shuffling,
and/or codon-shuffling (collectively referred to as "DNA
shuffling"). DNA shuffling may be employed to alter the activities
of antibodies of the invention or fragments thereof (e.g.,
antibodies or fragments thereof with higher affinities and lower
dissociation rates). See, generally, U.S. Pat. Nos. 5,605,793,
5,811,238, 5,830,721, 5,834,252, and 5,837,458; Patten et al.,
(1997) Curr. Opinion Biotechnol. 8:724-33; Harayama, (1998) Trends
Biotechnol. 16(2):76-82; Hansson et al., (1999) J. Mol. Biol.
287:265-76; and Lorenzo and Blasco, (1998) Biotechniques
24(2):308-313 (each of these patents and publications are hereby
incorporated by reference in its entirety). Antibodies or fragments
thereof, or the encoded antibodies or fragments thereof, may be
altered by being subjected to random mutagenesis by error-prone
PCR, random nucleotide insertion or other methods prior to
recombination. A polynucleotide encoding an antibody or fragment
thereof that specifically binds to a HER3 protein may be recombined
with one or more components, motifs, sections, parts, domains,
fragments, etc. of one or more heterologous molecules.
[0254] Moreover, the antibodies or fragments thereof can be fused
to marker sequences, such as a peptide to facilitate purification.
In preferred embodiments, the marker amino acid sequence is a
hexa-histidine (SEQ ID NO: 495) peptide, such as the tag provided
in a pQE vector (QIAGEN, Inc., 9259 Eton Avenue, Chatsworth,
Calif., 91311), among others, many of which are commercially
available. As described in Gentz et al., (1989) Proc. Natl. Acad.
Sci. USA 86:821-824, for instance, hexa-histidine (SEQ ID NO: 495)
provides for convenient purification of the fusion protein. Other
peptide tags useful for purification include, but are not limited

[0256] The present invention further encompasses uses of antibodies
or fragments thereof conjugated to a therapeutic moiety. An
antibody or fragment thereof may be conjugated to a therapeutic
moiety such as a cytotoxin, e.g., a cytostatic or cytocidal agent,
a therapeutic agent or a radioactive metal ion, e.g.,
alpha-emitters. A cytotoxin or cytotoxic agent includes any agent
that is detrimental to cells.
[0257] Further, an antibody or fragment thereof may be conjugated
to a therapeutic moiety or drug moiety that modifies a given
biological response. Therapeutic moieties or drug moieties are not
to be construed as limited to classical chemical therapeutic
agents. For example, the drug moiety may be a protein, peptide, or
polypeptide possessing a desired biological activity. Such proteins
may include, for example, a toxin such as abrin, ricin A,
pseudomonas exotoxin, cholera toxin, or diphtheria toxin; a protein
such as tumor necrosis factor, .alpha.-interferon,
.beta.-interferon, nerve growth factor, platelet derived growth
factor, tissue plasminogen activator, an apoptotic agent, an
anti-angiogenic agent; or, a biological response modifier such as,
for example, a lymphokine. In one embodiment, the anti-HER3
antibody, or a fragment thereof, conjugated to a therapeutic
moiety, such as a cytotoxin, a drug (e.g., an immunosuppressant) or
a radiotoxin. Such conjugates are referred to herein as
"immunoconjugates". Immunoconjugates that include one or more
cytotoxins are referred to as "immunotoxins." A cytotoxin or
cytotoxic agent includes any agent that is detrimental to (e.g.,
kills) cells. Examples include taxon, cytochalasin B, gramicidin D,
ethidium bromide, emetine, mitomycin, etoposide, tenoposide,
vincristine, vinblastine, t. colchicin, doxorubicin, daunorubicin,
dihydroxy anthracin dione, mitoxantrone, mithramycin, actinomycin
D, 1-dehydrotestosterone, glucocorticoids, procaine, tetracaine,
lidocaine, propranolol, and puromycin and analogs or homologs
thereof. Therapeutic agents also include, for example,
antimetabolites (e.g., methotrexate, 6-mercaptopurine,
6-thioguanine, cytarabine, 5-fluorouracil decarbazine), ablating
agents (e.g., mechlorethamine, thioepa chloraxnbucil, meiphalan,
carmustine (BSNU) and lomustine (CCNU), cyclothosphamide, busulfan,
dibromomannitol, streptozotocin, mitomycin C, and
cis-dichlorodiamine platinum (II) (DDP) cisplatin, anthracyclines
(e.g., daunorubicin (formerly daunomycin) and doxorubicin),
antibiotics (e.g., dactinomycin (formerly actinomycin), bleomycin,
mithramycin, and anthramycin (AMC)), and anti-mitotic agents (e.g.,
vincristine and vinblastine). (See e.g., Seattle Genetics
US20090304721).
[0258] Other examples of therapeutic cytotoxins that can be
conjugated to an antibody of the invention include duocarmycins,
calicheamicins, maytansines and auristatins, and derivatives
thereof. An example of a calicheamicin antibody conjugate is
commercially available (Mylotarg.TM.; Wyeth-Ayerst).
[0259] Cytoxins can be conjugated to antibodies of the invention
using linker technology available in the art. Examples of linker
types that have been used to conjugate a cytotoxin to an antibody
include, but are not limited to, hydrazones, thioethers, esters,
disulfides and peptide-containing linkers. A linker can be chosen
that is, for example, susceptible to cleavage by low pH within the
lysosomal compartment or susceptible to cleavage by proteases, such
as proteases preferentially expressed in tumor tissue such as
cathepsins (e.g., cathepsins B, C, D).

[0261] Antibodies of the present invention also can be conjugated
to a radioactive isotope to generate cytotoxic
radiopharmaceuticals, also referred to as radioimmunoconjugates.
Examples of radioactive isotopes that can be conjugated to
antibodies for use diagnostically or therapeutically include, but
are not limited to, iodine.sup.131, yttrium.sup.90, and
lutetium.sup.177. Method for preparing radioimmunconjugates are
established in the art. Examples of radioimmunoconjugates are
commercially available, including Zevalin.TM. (DEC Pharmaceuticals)
and Bexxar.TM. (Corixa Pharmaceuticals), and similar methods can be
used to prepare radioimmunoconjugates using the antibodies of the
invention. In certain embodiments, the macrocyclic chelator is
1,4,7,10-tetraazacyclododecane-N,N',N'',N'''-tetraacetic acid
(DOTA) which can be attached to the antibody via a linker molecule.
Such linker molecules are commonly known in the art and described

particularly useful for immunoassays or purification of the target
antigen. Such solid supports include, but are not limited to,

Methods of Producing Antibodies of the Invention
(i) Nucleic Acids Encoding the Antibodies
[0270] The invention provides substantially purified nucleic acid
molecules which encode polypeptides comprising segments or domains
of the HER3-binding antibody chains described above. Some of the
nucleic acids of the invention comprise the nucleotide sequence
encoding the HER3 antibody heavy chain variable region, and/or the
nucleotide sequence encoding the light chain variable region. In a
specific embodiment, the nucleic acid molecules are those
identified in Table 1. Some other nucleic acid molecules of the
invention comprise nucleotide sequences that are substantially
identical (e.g., at least 65, 80%, 95%, or 99%) to the nucleotide
sequences of those identified in Table 1. When expressed from
appropriate expression vectors, polypeptides encoded by these
polynucleotides are capable of exhibiting HER3 antigen binding
capacity.
[0271] Also provided in the invention are polynucleotides which
encode at least one CDR region and usually all three CDR regions
from the heavy or light chain of the HER3-binding antibody set
forth above. Some other polynucleotides encode all or substantially
all of the variable region sequence of the heavy chain and/or the
light chain of the HER3-binding antibody set forth above. Because
of the degeneracy of the code, a variety of nucleic acid sequences
will encode each of the immunoglobulin amino acid sequences.
[0272] The nucleic acid molecules of the invention can encode both
a variable region and a constant region of the antibody. Some of
nucleic acid sequences of the invention comprise nucleotides
encoding a mature heavy chain variable region sequence that is
substantially identical (e.g., at least 80%, 90%, or 99%) to the
mature heavy chain variable region sequence of a HER3 antibody set
forth in Table 1. Some other nucleic acid sequences comprising
nucleotide encoding a mature light chain variable region sequence
that is substantially identical (e.g., at least 80%, 90%, or 99%)
to the mature light chain variable region sequence of a HER3
antibody set forth in Table 1.
[0273] The polynucleotide sequences can be produced by de novo
solid-phase DNA synthesis or by PCR mutagenesis of an existing
sequence (e.g., sequences as described in the Examples below)
encoding an HER3-binding antibody or its binding fragment. Direct
chemical synthesis of nucleic acids can be accomplished by methods
known in the art, such as the phosphotriester method of Narang et
al., (1979) Meth. Enzymol. 68:90; the phosphodiester method of
Brown et al., (1979) Meth. Enzymol. 68:109; the
diethylphosphoramidite method of Beaucage et al., (1981) Tetra.
Lett., 22:1859; and the solid support method of U.S. Pat. No.
4,458,066. Introducing mutations to a polynucleotide sequence by
PCR can be performed as described in, e.g., PCR Technology:
Principles and Applications for DNA Amplification, H. A. Erlich
(Ed.), Freeman Press, NY, NY, 1992; PCR Protocols: A Guide to
Methods and Applications, Innis et al. (Ed.), Academic Press, San
Diego, Calif., 1990; Manila et al., (1991) Nucleic Acids Res.
19:967; and Eckert et al., (1991) PCR Methods and Applications
1:17.
[0274] Also provided in the invention are expression vectors and
host cells for producing the HER3-binding antibodies described
above. Various expression vectors can be employed to express the
polynucleotides encoding the HER3-binding antibody chains or
binding fragments. Both viral-based and nonviral expression vectors
can be used to produce the antibodies in a mammalian host cell.
Nonviral vectors and systems include plasmids, episomal vectors,
typically with an expression cassette for expressing a protein or
RNA, and human artificial chromosomes (see, e.g., Harrington et
al., (1997) Nat Genet 15:345). For example, nonviral vectors useful
for expression of the HER3-binding polynucleotides and polypeptides
in mammalian (e.g., human) cells include pThioHis A, B & C,
pcDNA3.1/His, pEBVHis A, B & C, (Invitrogen, San Diego,
Calif.), MPSV vectors, and numerous other vectors known in the art
for expressing other proteins. Useful viral vectors include vectors
based on retroviruses, adenoviruses, adenoassociated viruses,
herpes viruses, vectors based on SV40, papilloma virus, HBP Epstein
Barr virus, vaccinia virus vectors and Semliki Forest virus (SFV).
See, Brent et al., (1995) supra; Smith, Annu. Rev. Microbiol.
49:807; and Rosenfeld et al., (1992) Cell 68:143.
[0275] The choice of expression vector depends on the intended host
cells in which the vector is to be expressed. Typically, the
expression vectors contain a promoter and other regulatory
sequences (e.g., enhancers) that are operably linked to the
polynucleotides encoding an HER3-binding antibody chain or
fragment. In some embodiments, an inducible promoter is employed to
prevent expression of inserted sequences except under inducing
conditions. Inducible promoters include, e.g., arabinose, lacZ,
metallothionein promoter or a heat shock promoter. Cultures of
transformed organisms can be expanded under noninducing conditions
without biasing the population for coding sequences whose
expression products are better tolerated by the host cells. In
addition to promoters, other regulatory elements may also be
required or desired for efficient expression of an HER3-binding
antibody chain or fragment. These elements typically include an ATG
initiation codon and adjacent ribosome binding site or other
sequences. In addition, the efficiency of expression may be
enhanced by the inclusion of enhancers appropriate to the cell
system in use (see, e.g., Scharf et al., (1994) Results Probl. Cell
Differ. 20:125; and Bittner et al., (1987) Meth. Enzymol.,
153:516). For example, the SV40 enhancer or CMV enhancer may be
used to increase expression in mammalian host cells.
[0276] The expression vectors may also provide a secretion signal
sequence position to form a fusion protein with polypeptides
encoded by inserted HER3-binding antibody sequences. More often,
the inserted HER3-binding antibody sequences are linked to a signal
sequences before inclusion in the vector. Vectors to be used to
receive sequences encoding HER3-binding antibody light and heavy
chain variable domains sometimes also encode constant regions or
parts thereof. Such vectors allow expression of the variable
regions as fusion proteins with the constant regions thereby
leading to production of intact antibodies or fragments thereof.
Typically, such constant regions are human.
[0277] The host cells for harboring and expressing the HER3-binding
antibody chains can be either prokaryotic or eukaryotic. E. coli is
one prokaryotic host useful for cloning and expressing the
polynucleotides of the present invention. Other microbial hosts
suitable for use include bacilli, such as Bacillus subtilis, and
other enterobacteriaceae, such as Salmonella, Serratia, and various
Pseudomonas species. In these prokaryotic hosts, one can also make
expression vectors, which typically contain expression control
sequences compatible with the host cell (e.g., an origin of
replication). In addition, any number of a variety of well-known
promoters will be present, such as the lactose promoter system, a
tryptophan (trp) promoter system, a beta-lactamase promoter system,
or a promoter system from phage lambda. The promoters typically
control expression, optionally with an operator sequence, and have
ribosome binding site sequences and the like, for initiating and
completing transcription and translation. Other microbes, such as
yeast, can also be employed to express HER3-binding polypeptides of
the invention. Insect cells in combination with baculovirus vectors
can also be used.
[0278] In some preferred embodiments, mammalian host cells are used
to express and produce the HER3-binding polypeptides of the present
invention. For example, they can be either a hybridoma cell line
expressing endogenous immunoglobulin genes (e.g., the 1D6.C9
myeloma hybridoma clone as described in the Examples) or a
mammalian cell line harboring an exogenous expression vector (e.g.,
the SP2/0 myeloma cells exemplified below). These include any
normal mortal or normal or abnormal immortal animal or human cell.
For example, a number of suitable host cell lines capable of
secreting intact immunoglobulins have been developed including the
CHO cell lines, various Cos cell lines, HeLa cells, myeloma cell
lines, transformed B-cells and hybridomas. The use of mammalian
tissue cell culture to express polypeptides is discussed generally
in, e.g., Winnacker, FROM GENES TO CLONES, VCH Publishers, N.Y.,
N.Y., 1987. Expression vectors for mammalian host cells can include
expression control sequences, such as an origin of replication, a
promoter, and an enhancer (see, e.g., Queen et al., (1986) Immunol.
Rev. 89:49-68), and necessary processing information sites, such as
ribosome binding sites, RNA splice sites, polyadenylation sites,
and transcriptional terminator sequences. These expression vectors
usually contain promoters derived from mammalian genes or from
mammalian viruses. Suitable promoters may be constitutive, cell
type-specific, stage-specific, and/or modulatable or regulatable.
Useful promoters include, but are not limited to, the
metallothionein promoter, the constitutive adenovirus major late
promoter, the dexamethasone-inducible MMTV promoter, the SV40
promoter, the MRP polIII promoter, the constitutive MPSV promoter,
the tetracycline-inducible CMV promoter (such as the human
immediate-early CMV promoter), the constitutive CMV promoter, and
promoter-enhancer combinations known in the art.
[0279] Methods for introducing expression vectors containing the
polynucleotide sequences of interest vary depending on the type of
cellular host. For example, calcium chloride transfection is
commonly utilized for prokaryotic cells, whereas calcium phosphate
treatment or electroporation may be used for other cellular hosts.
(See generally Sambrook, et al., supra). Other methods include,
e.g., electroporation, calcium phosphate treatment,
liposome-mediated transformation, injection and microinjection,
ballistic methods, virosomes, immunoliposomes, polycation:nucleic
acid conjugates, naked DNA, artificial virions, fusion to the
herpes virus structural protein VP22 (Elliot and O'Hare, (1997)
Cell 88:223), agent-enhanced uptake of DNA, and ex vivo
transduction. For long-term, high-yield production of recombinant
proteins, stable expression will often be desired. For example,
cell lines which stably express HER3-binding antibody chains or
binding fragments can be prepared using expression vectors of the
invention which contain viral origins of replication or endogenous
expression elements and a selectable marker gene. Following the
introduction of the vector, cells may be allowed to grow for 1-2
days in an enriched media before they are switched to selective
media. The purpose of the selectable marker is to confer resistance
to selection, and its presence allows growth of cells which
successfully express the introduced sequences in selective media.
Resistant, stably transfected cells can be proliferated using
tissue culture techniques appropriate to the cell type.
(ii) Generation of Monoclonal Antibodies of the Invention
[0280] Monoclonal antibodies (mAbs) can be produced by a variety of
techniques, including conventional monoclonal antibody methodology
e.g., the standard somatic cell hybridization technique of Kohler
and Milstein, (1975) Nature 256:495. Many techniques for producing
monoclonal antibody can be employed e.g., viral or oncogenic
transformation of B lymphocytes.
[0281] An animal system for preparing hybridomas is the murine
system. Hybridoma production in the mouse is a well established
procedure. Immunization protocols and techniques for isolation of
immunized splenocytes for fusion are known in the art. Fusion
partners (e.g., murine myeloma cells) and fusion procedures are
also known.
[0282] Chimeric or humanized antibodies of the present invention
can be prepared based on the sequence of a murine monoclonal
antibody prepared as described above. DNA encoding the heavy and
light chain immunoglobulins can be obtained from the murine
hybridoma of interest and engineered to contain non-murine (e.g.,
human) immunoglobulin sequences using standard molecular biology
techniques. For example, to create a chimeric antibody, the murine
variable regions can be linked to human constant regions using
methods known in the art (see e.g., U.S. Pat. No. 4,816,567 to
Cabilly et al.). To create a humanized antibody, the murine CDR
regions can be inserted into a human framework using methods known
in the art. See e.g., U.S. Pat. No. 5,225,539 to Winter, and U.S.
Pat. Nos. 5,530,101; 5,585,089; 5,693,762 and 6,180,370 to Queen et
al.
[0283] In a certain embodiment, the antibodies of the invention are
human monoclonal antibodies. Such human monoclonal antibodies
directed against HER3 can be generated using transgenic or
transchromosomic mice carrying parts of the human immune system
rather than the mouse system. These transgenic and transchromosomic
mice include mice referred to herein as HuMAb mice and KM mice,
respectively, and are collectively referred to herein as "human Ig
mice."
[0284] The HuMAb Mouse.RTM. (Medarex, Inc.) contains human
immunoglobulin gene miniloci that encode un-rearranged human heavy
(.mu. and .gamma.) and .kappa. light chain immunoglobulin
sequences, together with targeted mutations that inactivate the
endogenous .mu. and .kappa. chain loci (see e.g., Lonberg et al.,
(1994) Nature 368(6474): 856-859). Accordingly, the mice exhibit
reduced expression of mouse IgM or .kappa., and in response to
immunization, the introduced human heavy and light chain transgenes
undergo class switching and somatic mutation to generate high
affinity human IgG.kappa. monoclonal (Lonberg et al., (1994) supra;
reviewed in Lonberg, (1994) Handbook of Experimental Pharmacology
113:49-101; Lonberg and Huszar, (1995) Intern. Rev. Immunol.
13:65-93, and Harding and Lonberg, (1995) Ann. N. Y. Acad. Sci.
764:536-546). The preparation and use of HuMAb mice, and the
genomic modifications carried by such mice, is further described in

[0285] In another embodiment, human antibodies of the invention can
be raised using a mouse that carries human immunoglobulin sequences
on transgenes and transchomosomes such as a mouse that carries a
human heavy chain transgene and a human light chain
transchromosome. Such mice, referred to herein as "KM mice", are
described in detail in PCT Publication WO 02/43478 to Ishida et
al.
[0286] Still further, alternative transgenic animal systems
expressing human immunoglobulin genes are available in the art and
can be used to raise HER3-binding antibodies of the invention. For
example, an alternative transgenic system referred to as the
Xenomouse (Abgenix, Inc.) can be used. Such mice are described in,
e.g., U.S. Pat. Nos. 5,939,598; 6,075,181; 6,114,598; 6, 150,584
and 6,162,963 to Kucherlapati et al.
[0287] Moreover, alternative transchromosomic animal systems
expressing human immunoglobulin genes are available in the art and
can be used to raise HER3-binding antibodies of the invention. For
example, mice carrying both a human heavy chain transchromosome and
a human light chain tranchromosome, referred to as "TC mice" can be
used; such mice are described in Tomizuka et al., (2000) Proc.
Natl. Acad. Sci. USA 97:722-727. Furthermore, cows carrying human
heavy and light chain transchromosomes have been described in the
art (Kuroiwa et al., (2002) Nature Biotechnology 20:889-894) and
can be used to raise HER3-binding antibodies of the invention.
[0288] Human monoclonal antibodies of the invention can also be
prepared using phage display methods for screening libraries of
human immunoglobulin genes. Such phage display methods for
isolating human antibodies are established in the art or described
in the examples below. See for example: U.S. Pat. Nos. 5,223,409;
5,403,484; and U.S. Pat. No. 5,571,698 to Ladner et al.; U.S. Pat.
Nos. 5,427,908 and 5,580,717 to Dower et al.; U.S. Pat. Nos.
5,969,108 and 6,172,197 to McCafferty et al.; and U.S. Pat. Nos.
5,885,793; 6,521,404; 6,544,731; 6,555,313; 6,582,915 and 6,593,081
to Griffiths et al.
[0289] Human monoclonal antibodies of the invention can also be
prepared using SCID mice into which human immune cells have been
reconstituted such that a human antibody response can be generated
upon immunization. Such mice are described in, for example, U.S.
Pat. Nos. 5,476,996 and 5,698,767 to Wilson et al.
(iii) Framework or Fc Engineering
[0290] Engineered antibodies of the invention include those in
which modifications have been made to framework residues within VH
and/or VL, e.g. to improve the properties of the antibody.
Typically such framework modifications are made to decrease the
immunogenicity of the antibody. For example, one approach is to
"backmutate" one or more framework residues to the corresponding
germline sequence. More specifically, an antibody that has
undergone somatic mutation may contain framework residues that
differ from the germline sequence from which the antibody is
derived. Such residues can be identified by comparing the antibody
framework sequences to the germline sequences from which the
antibody is derived. To return the framework region sequences to
their germline configuration, the somatic mutations can be
"backmutated" to the germline sequence by, for example,
site-directed mutagenesis. Such "backmutated" antibodies are also
intended to be encompassed by the invention.
[0291] Another type of framework modification involves mutating one
or more residues within the framework region, or even within one or
more CDR regions, to remove T cell-epitopes to thereby reduce the
potential immunogenicity of the antibody. This approach is also
referred to as "deimmunization" and is described in further detail
in U.S. Patent Publication No. 20030153043 by Carr et al.
[0292] In addition or alternative to modifications made within the
framework or CDR regions, antibodies of the invention may be
engineered to include modifications within the Fc region, typically
to alter one or more functional properties of the antibody, such as
serum half-life, complement fixation, Fc receptor binding, and/or
antigen-dependent cellular cytotoxicity. Furthermore, an antibody
of the invention may be chemically modified (e.g., one or more
chemical moieties can be attached to the antibody) or be modified
to alter its glycosylation, again to alter one or more functional
properties of the antibody. Each of these embodiments is described
in further detail below. The numbering of residues in the Fc region
is that of the EU index of Kabat.
[0293] In one embodiment, the hinge region of CH1 is modified such
that the number of cysteine residues in the hinge region is
altered, e.g., increased or decreased. This approach is described
further in U.S. Pat. No. 5,677,425 by Bodmer et al. The number of
cysteine residues in the hinge region of CH1 is altered to, for
example, facilitate assembly of the light and heavy chains or to
increase or decrease the stability of the antibody.
[0294] In another embodiment, the Fc hinge region of an antibody is
mutated to decrease the biological half-life of the antibody. More
specifically, one or more amino acid mutations are introduced into
the CH2-CH3 domain interface region of the Fc-hinge fragment such
that the antibody has impaired Staphylococcyl protein A (SpA)
binding relative to native Fc-hinge domain SpA binding. This
approach is described in further detail in U.S. Pat. No. 6,165,745
by Ward et al.
[0295] In yet other embodiments, the Fc region is altered by
replacing at least one amino acid residue with a different amino
acid residue to alter the effector functions of the antibody. For
example, one or more amino acids can be replaced with a different
amino acid residue such that the antibody has an altered affinity
for an effector ligand but retains the antigen-binding ability of
the parent antibody. The effector ligand to which affinity is
altered can be, for example, an Fc receptor or the C1 component of
complement. This approach is described in further detail in U.S.
Pat. Nos. 5,624,821 and 5,648,260, both by Winter et al.
[0296] In another embodiment, one or more amino acids selected from
amino acid residues can be replaced with a different amino acid
residue such that the antibody has altered C1q binding and/or
reduced or abolished complement dependent cytotoxicity (CDC). This
approach is described in further detail in U.S. Pat. No. 6,194,551
by Idusogie et al.
[0297] In another embodiment, one or more amino acid residues are
altered to thereby alter the ability of the antibody to fix
complement. This approach is described further in PCT Publication
WO 94/29351 by Bodmer et al.
[0298] In yet another embodiment, the Fc region is modified to
increase the ability of the antibody to mediate antibody dependent
cellular cytotoxicity (ADCC) and/or to increase the affinity of the
antibody for an Fc.gamma. receptor by modifying one or more amino
acids. This approach is described further in PCT Publication WO
00/42072 by Presta. Moreover, the binding sites on human IgG1 for
Fc.gamma.RI, Fc.gamma.RII, Fc.gamma.RIII and FcRn have been mapped
and variants with improved binding have been described (see Shields
et al., (2001) J. Biol. Chen. 276:6591-6604).
[0299] In still another embodiment, the glycosylation of an
antibody is modified. For example, an aglycoslated antibody can be
made (i.e., the antibody lacks glycosylation). Glycosylation can be
altered to, for example, increase the affinity of the antibody for
"antigen`. Such carbohydrate modifications can be accomplished by,
for example, altering one or more sites of glycosylation within the
antibody sequence. For example, one or more amino acid
substitutions can be made that result in elimination of one or more
variable region framework glycosylation sites to thereby eliminate
glycosylation at that site. Such aglycosylation may increase the
affinity of the antibody for antigen. Such an approach is described
in further detail in U.S. Pat. Nos. 5,714,350 and 6,350,861 by Co
et al.
[0300] Additionally or alternatively, an antibody can be made that
has an altered type of glycosylation, such as a hypofucosylated
antibody having reduced amounts of fucosyl residues or an antibody
having increased bisecting GlcNac structures. Such altered
glycosylation patterns have been demonstrated to increase the ADCC
ability of antibodies. Such carbohydrate modifications can be
accomplished by, for example, expressing the antibody in a host
cell with altered glycosylation machinery. Cells with altered
glycosylation machinery have been described in the art and can be
used as host cells in which to express recombinant antibodies of
the invention to thereby produce an antibody with altered
glycosylation. For example, EP 1,176,195 by Hang et al. describes a
cell line with a functionally disrupted FUT8 gene, which encodes a
fucosyl transferase, such that antibodies expressed in such a cell
line exhibit hypofucosylation. PCT Publication WO 03/035835 by
Presta describes a variant CHO cell line, Lec13 cells, with reduced
ability to attach fucose to Asn(297)-linked carbohydrates, also
resulting in hypofucosylation of antibodies expressed in that host
cell (see also Shields et al., (2002) J. Biol. Chem.
277:26733-26740). PCT Publication WO 99/54342 by Umana et al.
describes cell lines engineered to express glycoprotein-modifying
glycosyltransferases (e.g., beta(1,4)-N
acetylglucosaminyltransferase III (GnTIII)) such that antibodies
expressed in the engineered cell lines exhibit increased bisecting
GlcNac structures which results in increased ADCC activity of the
antibodies (see also Umana et al., (1999) Nat. Biotech.
17:176-180).
[0301] In another embodiment, the antibody is modified to increase
its biological half-life. Various approaches are possible. For
example, one or more of the following mutations can be introduced:
T252L, T254S, T256F, as described in U.S. Pat. No. 6,277,375 to
Ward. Alternatively, to increase the biological half life, the
antibody can be altered within the CH1 or CL region to contain a
salvage receptor binding epitope taken from two loops of a CH2
domain of an Fc region of an IgG, as described in U.S. Pat. Nos.
5,869,046 and 6,121,022 by Presta et al.
(iv) Methods of Engineering Altered Antibodies
[0302] As discussed above, the HER3-binding antibodies having VH
and VL sequences or full length heavy and light chain sequences
shown herein can be used to create new HER3-binding antibodies by
modifying full length heavy chain and/or light chain sequences, VH
and/or VL sequences, or the constant region(s) attached thereto.
Thus, in another aspect of the invention, the structural features
of a HER3-binding antibody of the invention are used to create
structurally related HER3-binding antibodies that retain at least
one functional property of the antibodies of the invention, such as
binding to human HER3 and also inhibiting one or more functional
properties of HER3 For example, one or more CDR regions of the
antibodies of the present invention, or mutations thereof, can be
combined recombinantly with known framework regions and/or other
CDRs to create additional, recombinantly-engineered, HER3-binding
antibodies of the invention, as discussed above. Other types of
modifications include those described in the previous section. The
starting material for the engineering method is one or more of the
VH and/or VL sequences provided herein, or one or more CDR regions
thereof. To create the engineered antibody, it is not necessary to
actually prepare (i.e., express as a protein) an antibody having
one or more of the VH and/or VL sequences provided herein, or one
or more CDR regions thereof. Rather, the information contained in
the sequence(s) is used as the starting material to create a
"second generation" sequence(s) derived from the original
sequence(s) and then the "second generation" sequence(s) is
prepared and expressed as a protein.
[0303] Accordingly, in another embodiment, the invention provides a
method for preparing a HER3-binding antibody consisting of: a heavy
chain variable region antibody sequence having a CDR1 sequence
selected from the group consisting of SEQ ID NOs: 2, 8, 20, 26, 38,
44, 56, 62, 74, 80, 92, 98, 110, 116, 128, 134, 146, 152, 164, 170,
182, 188, 200, 206, 218, 224, 236, 242, 254, 260, 272, 278, 290,
296, 308, 314, 326, 332, 344, 350, 362, and 368; a CDR2 sequence
selected from the group consisting of SEQ ID NOs: 3, 9, 21, 27, 39,
45, 57, 63, 75, 81, 93, 99, 111, 117, 129, 135, 147, 153, 165, 171,
183, 189, 201, 207, 219, 225, 237, 243, 255, 261, 273, 279, 291,
297, 309, 315, 327, 333, 345, 351, 363, and 369; and/or a CDR3
sequence selected from the group consisting of SEQ ID NOs: 4, 10,
22, 28, 40, 46, 58, 64, 75, 82, 94, 100, 112, 118, 130, 136, 148,
154, 166, 172, 184, 190, 202, 208, 220, 226, 238, 244, 256, 262,
274, 280, 292, 298, 310, 316, 328, 334, 346, 352, 364, and 370; and
a light chain variable region antibody sequence having a CDR1
sequence selected from the group consisting of SEQ ID NOs: 5, 11,
23, 29, 41, 47, 59, 65, 77, 83, 95, 101, 113, 119, 131, 137, 149,
155, 167, 173, 185, 191, 203, 209, 221, 227, 239, 245, 257, 263,
275, 281, 293, 299, 311, 317, 329, 335, 347, 353, 365, and 371; a
CDR2 sequence selected from the group consisting of SEQ ID NOs: 6,
12, 24, 30, 42, 48, 60, 66, 78, 84, 96, 102, 114, 120, 132, 138,
150, 156, 168, 174, 186, 192, 204, 210, 222, 228, 240, 246, 258,
264, 276, 282, 294, 300, 312, 318, 330, 336, 348, 354, 366, and
372; and/or a CDR3 sequence selected from the group consisting of
SEQ ID NOs: 7, 13, 25, 31, 43, 49, 61, 67, 79, 85, 97, 103, 115,
121, 133, 139, 151, 157, 169, 175, 187, 193, 205, 211, 223, 229,
241, 247, 259, 265, 277, 283, 295, 301, 313, 319, 331, 337, 349,
355, 367, and 373; altering at least one amino acid residue within
the heavy chain variable region antibody sequence and/or the light
chain variable region antibody sequence to create at least one
altered antibody sequence; and expressing the altered antibody
sequence as a protein. The altered antibody sequence can also be
prepared by screening antibody libraries having fixed CDR3
sequences or minimal essential binding determinants as described in
US20050255552 and diversity on CDR1 and CDR2 sequences. The
screening can be performed according to any screening technology
appropriate for screening antibodies from antibody libraries, such
as phage display technology.
[0304] Standard molecular biology techniques can be used to prepare
and express the altered antibody sequence. The antibody encoded by
the altered antibody sequence(s) is one that retains one, some or
all of the functional properties of the HER3-binding antibodies
described herein, which functional properties include, but are not
limited to, specifically binding to human and/or cynomologus HER3;
the antibody binds to HER3 and neutralizes HER3 biological activity
by inhibiting the HER signaling activity in a phospho-HER
assay.
[0305] The functional properties of the altered antibodies can be
assessed using standard assays available in the art and/or
described herein, such as those set forth in the Examples (e.g.,
ELISAs).
[0306] In certain embodiments of the methods of engineering
antibodies of the invention, mutations can be introduced randomly
or selectively along all or part of an HER3-binding antibody coding
sequence and the resulting modified HER3-binding antibodies can be
screened for binding activity and/or other functional properties as
described herein. Mutational methods have been described in the
art. For example, PCT Publication WO 02/092780 by Short describes
methods for creating and screening antibody mutations using
saturation mutagenesis, synthetic ligation assembly, or a
combination thereof. Alternatively, PCT Publication WO 03/074679 by
Lazar et al. describes methods of using computational screening
methods to optimize physiochemical properties of antibodies.
Characterization of the Antibodies of the Invention
[0307] The antibodies of the invention can be characterized by
various functional assays. For example, they can be characterized
by their ability to neutralize biological activity by inhibiting
HER signaling in a phospho-HER assay as described herein, their
affinity to a HER3 protein (e.g., human and/or cynomologus HER3),
the epitope binning, their resistance to proteolysis, and their
ability to block HER3 downstream signaling. Various methods can be
used to measure HER3-mediated signaling. For example, the HER
signaling pathway can be monitored by (i) measurement of
phospho-HER3; (ii) measurement of phosphorylation of HER3 or other
downstream signaling proteins (e.g. Akt), (iii) ligand blocking
assays as described herein, (iv) heterodimer formation, (v) HER3
dependent gene expression signature, (vi) receptor internalization,
and (vii) HER3 driven cell phenotypes (e.g. proliferation).
[0308] The ability of an antibody to bind to HER3 can be detected
by labelling the antibody of interest directly, or the antibody may
be unlabelled and binding detected indirectly using various
sandwich assay formats known in the art.
[0309] In some embodiments, the HER3-binding antibodies of the
invention block or compete with binding of a reference HER3-binding
antibody to a HER3 polypeptide or protein. These can be fully human
HER3-binding antibodies described above. They can also be other
mouse, chimeric or humanized HER3-binding antibodies which bind to
the same epitope as the reference antibody. The capacity to block
or compete with the reference antibody binding indicates that a
HER3-binding antibody under test binds to the same or similar
epitope as that defined by the reference antibody, or to an epitope
which is sufficiently proximal to the epitope bound by the
reference HER3-binding antibody. Such antibodies are especially
likely to share the advantageous properties identified for the
reference antibody. The capacity to block or compete with the
reference antibody may be determined by, e.g., a competition
binding assay. With a competition binding assay, the antibody under
test is examined for ability to inhibit specific binding of the
reference antibody to a common antigen, such as a HER3 polypeptide
or protein. A test antibody competes with the reference antibody
for specific binding to the antigen if an excess of the test
antibody substantially inhibits binding of the reference antibody.
Substantial inhibition means that the test antibody reduces
specific binding of the reference antibody usually by at least 10%,
25%, 50%, 75%, or 90%.
[0310] There are a number of known competition binding assays that
can be used to assess competition of a HER3-binding antibody with
the reference HER3-binding antibody for binding to a HER3 protein.
These include, e.g., solid phase direct or indirect
radioimmunoassay (RIA), solid phase direct or indirect enzyme
immunoassay (EIA), sandwich competition assay (see Stahli et al.,
(1983) Methods in Enzymology 9:242-253); solid phase direct
biotin-avidin EIA (see Kirkland et al., (1986) J. Immunol.
137:3614-3619); solid phase direct labeled assay, solid phase
direct labeled sandwich assay (see Harlow & Lane, supra); solid
phase direct label RIA using I-125 label (see Morel et al., (1988)
Molec. Immunol. 25:7-15); solid phase direct biotin-avidin EIA
(Cheung et al., (1990) Virology 176:546-552); and direct labeled
RIA (Moldenhauer et al., (1990) Scand. J. Immunol. 32:77-82).
Typically, such an assay involves the use of purified antigen bound
to a solid surface or cells bearing either of these, an unlabelled
test HER3-binding antibody and a labelled reference antibody.
Competitive inhibition is measured by determining the amount of
label bound to the solid surface or cells in the presence of the
test antibody. Usually the test antibody is present in excess.
Antibodies identified by competition assay (competing antibodies)
include antibodies binding to the same epitope as the reference
antibody and antibodies binding to an adjacent epitope sufficiently
proximal to the epitope bound by the reference antibody for steric
hindrance to occur.
[0311] To determine if the selected HER3-binding monoclonal
antibodies bind to unique epitopes, each antibody can be
biotinylated using commercially available reagents (e.g., reagents
from Pierce, Rockford, Ill.). Competition studies using unlabeled
monoclonal antibodies and biotinylated monoclonal antibodies can be
performed using a HER3 polypeptide coated-ELISA plates.
Biotinylated MAb binding can be detected with a
strep-avidin-alkaline phosphatase probe. To determine the isotype
of a purified HER3-binding antibody, isotype ELISAs can be
performed. For example, wells of microtiter plates can be coated
with 1 .mu.g/ml of anti-human IgG overnight at 4.degree. C. After
blocking with 1% BSA, the plates are reacted with 1 .mu.g/ml or
less of the monoclonal HER3-binding antibody or purified isotype
controls, at ambient temperature for one to two hours. The wells
can then be reacted with either human IgG1 or human IgM-specific
alkaline phosphatase-conjugated probes. Plates are then developed
and analyzed so that the isotype of the purified antibody can be
determined.
[0312] To demonstrate binding of monoclonal HER3-binding antibodies
to live cells expressing a HER3 polypeptide, flow cytometry can be
used. Briefly, cell lines expressing HER3 (grown under standard
growth conditions) can be mixed with various concentrations of a
HER3-binding antibody in PBS containing 0.1% BSA and 10% fetal calf
serum, and incubated at 4.degree. C. for 1 hour. After washing, the
cells are reacted with Fluorescein-labeled anti-human IgG antibody
under the same conditions as the primary antibody staining. The
samples can be analyzed by FACScan instrument using light and side
scatter properties to gate on single cells. An alternative assay
using fluorescence microscopy may be used (in addition to or
instead of) the flow cytometry assay. Cells can be stained exactly
as described above and examined by fluorescence microscopy. This
method allows visualization of individual cells, but may have
diminished sensitivity depending on the density of the antigen.
[0313] HER3-binding antibodies of the invention can be further
tested for reactivity with a HER3 polypeptide or antigenic fragment
by Western blotting. Briefly, purified HER3 polypeptides or fusion
proteins, or cell extracts from cells expressing HER3 can be
prepared and subjected to sodium dodecyl sulfate polyacrylamide gel
electrophoresis. After electrophoresis, the separated antigens are
transferred to nitrocellulose membranes, blocked with 10% fetal
calf serum, and probed with the monoclonal antibodies to be tested.
Human IgG binding can be detected using anti-human IgG alkaline
phosphatase and developed with BCIP/NBT substrate tablets (Sigma
Chem. Co., St. Louis, Mo.).
[0314] A number of readouts can be used to assess the efficacy, and
specificity, of HER3 antibodies in cell-based assays of
ligand-induced heterodimer formation. Activity can be assessed by
one or more of the following:
[0315] (i) Inhibition of ligand-induced heterodimerisation of HER2
with other EGF family members in a target cell line, for example
MCF-7 breast cancer cells. Immunoprecipitation of HER2 complexes
from cell lysates can be performed with a receptor-specific
antibody, and the absence/presence of other EGF receptors and their
biologically relevant ligands within the complex can be analysed
following electrophoresis/Western transfer by probing with
antibodies to other EGF receptors.
[0316] (ii) Inhibition of the activation of signaling pathways by
ligand-activated heterodimers. Association with HER3 appears key
for other members of the EGF family of receptors to elicit maximal
cellular response following ligand binding. In the case of the
kinase-defective HER3, HER2 provides a functional tyrosine kinase
domain to enable signaling to occur following binding of growth
factor ligands. Thus, cells co-expressing HER2 and HER3 can be
treated with ligand, for example heregulin, in the absence and
presence of inhibitor and the effect on HER3 tyrosine
phosphorylation monitored by a number of ways including
immunoprecipitation of HER3 from treated cell lysates and
subsequent Western blotting using anti-phosphotyrosine antibodies
(see Agus op. cit. for details). Alternatively, a high-throughput
assay can be developed by trapping HER3 from solubilized lysates
onto the wells of a 96-well plate coated with an anti-HER3 receptor
antibody, and the level of tyrosine phosphorylation measured using,
for example, europium-labelled anti-phosphotyrosine antibodies, as
embodied by Waddleton et al., (2002) Anal. Biochem.
309:150-157.
[0317] In a broader extension of this approach, effector molecules
known to be activated downstream of activated receptor
heterodimers, such as mitogen-activated protein kinases (MAPK) and
Akt, may be analysed directly, by immunoprecipitation from treated
lysates and blotting with antibodies that detect the activated
forms of these proteins, or by analysing the ability of these
proteins to modify/activate specific substrates.
[0318] (iii) Inhibition of ligand-induced cellular proliferation. A
variety of cell lines are known to co-express combinations of ErbB
receptors, for example many breast and prostate cancer cell lines.
Assays may be performed in 24/48/96-well formats with the readout
based around DNA synthesis (tritiated thymidine incorporation),
increase in cell number (crystal violet staining) etc.
[0319] A number of readouts can be used to assess the efficacy, and
specificity, of HER3 antibodies in cell-based assays of
ligand-independent homo- and heterodimer formation. For example,
HER2 overexpression triggers ligand-independent activation of the
kinase domain as a result of spontaneous dimer formation. Over
expressed HER2 generates either homo- or heterodimers with other
HER molecules such as HER1, HER3 and HER4.
[0320] Ability of antibodies or fragments thereof to block in vivo
growth of tumour xenografts of human tumour cell lines whose
tumorigenic phenotype is known to be at least partly dependent on
ligand activation of HER3 heterodimer cell signaling e.g. BxPC3
pancreatic cancer cells etc. This can be assessed in
immunocompromised mice either alone or in combination with an
appropriate cytotoxic agent for the cell line in question. Examples
of functional assays are also described in the Example section
below.

the antibodies of the invention. In some embodiments, the present
invention provides methods of treating or preventing cancers
associated with a HER signaling pathway by administering to a
subject in need thereof an effective amount of the antibodies of
the invention.
[0322] In a specific embodiment, the present invention provides
methods of treating cancers associated with a HER signaling pathway
that include, but are not limited to breast cancer, colorectal
cancer, lung cancer, multiple myeloma, ovarian cancer, liver
cancer, gastric cancer, pancreatic cancer, acute myeloid leukemia,
chronic myeloid leukemia, osteosarcoma, squamous cell carcinoma,
peripheral nerve sheath tumors schwannoma, head and neck cancer,
bladder cancer, esophageal cancer, Barretts esophageal cancer,
glioblastoma, clear cell sarcoma of soft tissue, malignant
mesothelioma, neurofibromatosis, renal cancer, melanoma, prostate
cancer, benign prostatic hyperplasia (BPH), gynacomastica, and
endometriosis.
[0323] In one embodiment, the invention pertains to treating
esophageal cancer using the HER3 antibodies or fragments
thereof.
[0324] In one embodiment, the invention pertains to treating benign
prostatic hyperplasia (BPH) using the HER3 antibodies or fragments
thereof. BHP is a common disease in aging males that is
characterized by a non-neoplastic enlargement of the prostate
leading to pressure on the urethra and resulting in urination and
bladder problems (Mahapokail W, van Sluijs F J & Schalken J A.
2000 Prostate Cancer and Prostatic Diseases 3, 28-33). Anatomic or
microscopic evidence of BPH is present at autopsy in approximately
55% of men aged 60-70 years. Transurethal resection of the prostate
has been the treatment of choice for many years. Consequently, BPH
is one of the most common reasons for surgical intervention among
elderly men. Less invasive methods of treatment include:
[0325] (i) Alpha 1-blockers (doxazosin, prazosin, tamsulosin,
terazosin, and alfuzosin) are a class of medications also used to
treat high blood pressure. These medications relax the muscles of
the bladder neck and prostate thus allowing easier urination.
[0326] (ii) Finasteride and dutasteride lower androgen levels thus
reducing the size of the prostate gland, increasing urine flow
rate, and decreasing symptoms of BPH. It may take 3 to 6 months
before improvement in symptoms is observed. Potential side effects
related to the use of finasteride and dutasteride include decreased
sex drive and impotence
[0327] The results in the Experiments section demonstrate for the
first time that BPH is a neuregulin-dependent indication. The
finding also show that MOR10703 significantly reduced prostate size
in sexually mature rats without affecting hormone levels suggests
that MOR10703 could be useful for the treatment of BPH.
[0328] To further test MOR10703 and other HER3 antibodies as
therapeutics for BPH, primary human BPH surgical specimens can be
transplanted into athymic mice or rats and effect of the Her3
antibodies studied using models (Otto U et al. Urol Int 1992; 48:
167-170). Alternatively, aspects of BPH can be induced in castrated
dogs via the long-term administration of
5.alpha.-Androstane-3.alpha., 17.beta.-diol plus estradiol and the
HER3 antibodies tested in these canine models (Walsh P C, Wilson J
D. J Clin Invest 1976; 57: 1093-1097).
[0329] In one embodiment, the invention pertains to treating
gynecomastia using the HER3 antibodies or fragments thereof. The
physical manifestation of gynecomastia is breast enlargement in
males, it normally occurs in both breasts but can sometimes be in
one only, known as asymmetrical or unilateral gynecosmastia.
Gynecomastia is commonly caused by:
[0330] (i) Elevated estrogen levels resulting in the ratio of
testosterone to oestrogen becoming unbalanced.
[0331] (ii) Androgen antagonists or anti-androgens used in the
treatment of prostate cancer or BPH. These drugs suppress
testosterone but by suppressing testosterone, oestrogen begins to
rise.
[0332] Although a number of experimental drugs are currently being
evaluated there are currently no approved treatments for
gynecomastia. Consequently gynecomastia is treated via surgical
removal of the breast tissue. The observation that MOR10703 induced
irreversible atrophy of the male mammary gland indicates that it
may be of benefit in the treatment of gynecomastia.
[0333] To further test MOR10703 and other HER3 antibodies for
treating human gynecomastia, transgenic mouse models of
gynecomastia can be used. These models have been developed by
expressing human aromatase in the mouse mammary gland and
recapitulate many aspects of human gynecomastia (Li et al.,
Endocrinology 2002; 143:4074-4083; Tekmal et al., Cancer Res 1996;
56:3180-318).
[0334] In one embodiment, the invention pertains to treating
gynecomastia using the HER3 antibodies or fragments thereof.
MOR10703 and other HER3 antibodies can also be examined for
treating endometriosis, a gynecological condition in which cells
from the lining of the uterus (endometrium) appear and flourish
outside the uterine cavity. The main, but not universal, symptom of
endometriosis is pelvic pain in various manifestations. Although
the underlying causes of endometriosis are not well characterized
is thought to be dependent on the presence of estrogen. Since
MOR10703 induced endometrial atrophy in female mice resulting in a
decrease in uterus weight, it may be used to treat endometriosis.
To further study the effects of MOR10703 and other HER3 antibodies
on endometriosis, human endometrium in the proliferative phase can
be implanted into the peritoneal cavity of normal cycling and
ovariectomized athymic mice or cycling non-obese diabetic
(NOD)-severe combined immuno-deficiency (SCID) mice, and these SCID
mice used as models (Grummer et al., 2001. Human Reproduction; 16;
1736-1743).
[0335] HER3 antibodies can also be used to treat or prevent other
disorders associated with aberrant or defective HER signaling,
including but are not limited to respiratory diseases,
osteoporosis, osteoarthritis, polycystic kidney disease, diabetes,
schizophrenia, vascular disease, cardiac disease, non-oncogenic
proliferative diseases, fibrosis, and neurodegenerative diseases
such as Alzheimer's disease.
[0336] Suitable agents for combination treatment with HER3-binding
antibodies include standard of care agents known in the art that
are able to modulate the ErbB signaling pathway. Suitable examples
of standard of care agents for HER2 include, but are not limited to
Herceptin and Tykerb. Suitable examples of standard of care agents
for EGFR include, but are not limited to Iressa, Tarceva, Erbitux
and Vectibix. Other agents that may be suitable for combination
treatment with HER3-binding antibodies include, but are not limited
to those that modulate receptor tyrosine kinases, G-protein coupled
receptors, growth/survival signal transduction pathways, nuclear
hormone receptors, apoptotic pathways, cell cycle and
angiogenesis.
Diagnostic Uses
[0337] In one aspect, the invention encompasses diagnostic assays
for determining HER3 protein and/or nucleic acid expression as well
as HER3 protein function, in the context of a biological sample
(e.g., blood, serum, cells, tissue) or from individual afflicted
with cancer, or is at risk of developing cancer.
[0338] Diagnostic assays, such as competitive assays rely on the
ability of a labelled analogue (the "tracer") to compete with the
test sample analyte for a limited number of binding sites on a
common binding partner. The binding partner generally is
insolubilized before or after the competition and then the tracer
and analyte bound to the binding partner are separated from the
unbound tracer and analyte. This separation is accomplished by
decanting (where the binding partner was preinsolubilized) or by
centrifuging (where the binding partner was precipitated after the
competitive reaction). The amount of test sample analyte is
inversely proportional to the amount of bound tracer as measured by
the amount of marker substance. Dose-response curves with known
amounts of analyte are prepared and compared with the test results
in order to quantitatively determine the amount of analyte present
in the test sample. These assays are called ELISA systems when
enzymes are used as the detectable markers. In an assay of this
form, competitive binding between antibodies and HER3-binding
antibodies results in the bound HER3 protein, preferably the HER3
epitopes of the invention, being a measure of antibodies in the
serum sample, most particularly, neutralizing antibodies in the
serum sample.
[0339] A significant advantage of the assay is that measurement is
made of neutralizing antibodies directly (i.e., those which
interfere with binding of HER3 protein, specifically, epitopes).
Such an assay, particularly in the form of an ELISA test has
considerable applications in the clinical environment and in
routine blood screening.
[0340] Another aspect of the invention provides methods for
determining HER3 nucleic acid expression or HER3 protein activity
in an individual to thereby select appropriate therapeutic or
prophylactic agents for that individual (referred to herein as
"pharmacogenomics"). Pharmacogenomics allows for the selection of
agents (e.g., drugs) for therapeutic or prophylactic treatment of
an individual based on the genotype of the individual (e.g., the
genotype of the individual examined to determine the ability of the
individual to respond to a particular agent.)
[0341] Yet another aspect of the invention pertains to monitoring
the influence of agents (e.g., drugs) on the expression or activity
of HER3 protein in clinical trials.
Pharmaceutical Compositions
[0342] To prepare pharmaceutical or sterile compositions including
a HER3-binding antibodies (intact or binding fragments), the
HER3-binding antibodies (intact or binding fragments) is mixed with
a pharmaceutically acceptable carrier or excipient. The
compositions can additionally contain one or more other therapeutic
agents that are suitable for treating or preventing cancer (breast
cancer, colorectal cancer, lung cancer, multiple myeloma, ovarian
cancer, liver cancer, gastric cancer, pancreatic cancer, acute
myeloid leukemia, chronic myeloid leukemia, osteosarcoma, squamous
cell carcinoma, peripheral nerve sheath tumors schwannoma, head and
neck cancer, bladder cancer, esophageal cancer, Barretts esophageal
cancer, glioblastoma, clear cell sarcoma of soft tissue, malignant
mesothelioma, neurofibromatosis, renal cancer, melanoma, prostate
cancer, benign prostatic hyperplasia (BPH), gynacomastica, and
endometriosis).
[0343] Formulations of therapeutic and diagnostic agents can be
prepared by mixing with physiologically acceptable carriers,
excipients, or stabilizers in the form of, e.g., lyophilized
powders, slurries, aqueous solutions, lotions, or suspensions (see,
e.g., Hardman et al., (2001) Goodman and Gilman's The
Pharmacological Basis of Therapeutics, McGraw-Hill, New York, N.Y.;
Gennaro (2000) Remington: The Science and Practice of Pharmacy,
Lippincott, Williams, and Wilkins, New York, N.Y.; Avis, et al.
(eds.) (1993) Pharmaceutical Dosage Forms: Parenteral Medications,
Marcel Dekker, NY; Lieberman, et al. (eds.) (1990) Pharmaceutical
Dosage Forms: Tablets, Marcel Dekker, NY; Lieberman, et al. (eds.)
(1990) Pharmaceutical Dosage Forms: Disperse Systems, Marcel
Dekker, NY; Weiner and Kotkoskie (2000) Excipient Toxicity and
Safety, Marcel Dekker, Inc., New York, N.Y.).
[0344] Selecting an administration regimen for a therapeutic
depends on several factors, including the serum or tissue turnover
rate of the entity, the level of symptoms, the immunogenicity of
the entity, and the accessibility of the target cells in the
biological matrix. In certain embodiments, an administration
regimen maximizes the amount of therapeutic delivered to the
patient consistent with an acceptable level of side effects.
Accordingly, the amount of biologic delivered depends in part on
the particular entity and the severity of the condition being
treated. Guidance in selecting appropriate doses of antibodies,
cytokines, and small molecules are available (see, e.g.,
Wawrzynczak (1996) Antibody Therapy, Bios Scientific Pub. Ltd,
Oxfordshire, UK; Kresina (ed.) (1991) Monoclonal Antibodies,
Cytokines and Arthritis, Marcel Dekker, New York, N.Y.; Bach (ed.)
(1993) Monoclonal Antibodies and Peptide Therapy in Autoimmune
Diseases, Marcel Dekker, New York, N.Y.; Baert et al., (2003) New
Engl. J. Med. 348:601-608; Milgrom et al., (1999) New Engl. J. Med.
341:1966-1973; Slamon et al., (2001) New Engl. J. Med. 344:783-792;
Beniaminovitz et al., (2000) New Engl. J. Med. 342:613-619; Ghosh
et al., (2003) New Engl. J. Med. 348:24-32; Lipsky et al., (2000)
New Engl. J. Med. 343:1594-1602).
[0345] Determination of the appropriate dose is made by the
clinician, e.g., using parameters or factors known or suspected in
the art to affect treatment or predicted to affect treatment.
Generally, the dose begins with an amount somewhat less than the
optimum dose and it is increased by small increments thereafter
until the desired or optimum effect is achieved relative to any
negative side effects. Important diagnostic measures include those
of symptoms of, e.g., the inflammation or level of inflammatory
cytokines produced.
[0346] Actual dosage levels of the active ingredients in the
pharmaceutical compositions of the present invention may be varied
so as to obtain an amount of the active ingredient which is
effective to achieve the desired therapeutic response for a
particular patient, composition, and mode of administration,
without being toxic to the patient. The selected dosage level will
depend upon a variety of pharmacokinetic factors including the
activity of the particular compositions of the present invention
employed, or the ester, salt or amide thereof, 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 compositions employed, the age,
sex, weight, condition, general health and prior medical history of
the patient being treated, and like factors known in the medical
arts.

the invention can be provided by continuous infusion, or by doses
at intervals of, e.g., one day, one week, or 1-7 times per week.
Doses may be provided intravenously, subcutaneously, topically,
orally, nasally, rectally, intramuscular, intracerebrally, or by
inhalation. A specific dose protocol is one involving the maximal

[0353] An effective amount for a particular patient may vary
depending on factors such as the condition being treated, the
overall health of the patient, the method route and dose of
administration and the severity of side affects (see, e.g., Maynard
et al., (1996) A Handbook of SOPs for Good Clinical Practice,
Interpharm Press, Boca Raton, Fla.; Dent (2001) Good Laboratory and
Good Clinical Practice, Urch Publ., London, UK).
[0354] The route of administration may be by, e.g., topical or
cutaneous application, injection or infusion by intravenous,
intraperitoneal, intracerebral, intramuscular, intraocular,
intraarterial, intracerebrospinal, intralesional, or by sustained
release systems or an implant (see, e.g., Sidman et al., (1983)
Biopolymers 22:547-556; Langer et al., (1981) J. Biomed. Mater.
Res. 15:167-277; Langer (1982) Chem. Tech. 12:98-105; Epstein et
al., (1985) Proc. Natl. Acad. Sci. USA 82:3688-3692; Hwang et al.,
(1980) Proc. Natl. Acad. Sci. USA 77:4030-4034; U.S. Pat. Nos.
6,350,466 and 6,316,024). Where necessary, the composition may also
include a solubilizing agent and a local anesthetic such as
lidocaine to ease pain at the site of the injection. In addition,
pulmonary administration can also be employed, e.g., by use of an
inhaler or nebulizer, and formulation with an aerosolizing agent.
See, e.g., U.S. Pat. Nos. 6,019,968, 5,985,320, 5,985,309,

98/31346, and WO 99/66903, each of which is incorporated herein by
reference their entirety.
[0355] A composition of the present invention may also be
administered via one or more routes of administration using one or
more of a variety of methods known in the art. As will be
appreciated by the skilled artisan, the route and/or mode of
administration will vary depending upon the desired results.
Selected routes of administration for antibodies or fragments
thereof of the invention include intravenous, intramuscular,
intradermal, intraperitoneal, subcutaneous, spinal or other
parenteral routes of administration, for example by injection or
infusion. Parenteral administration may represent modes of
administration other than enteral and topical administration,
usually by injection, and includes, without limitation,
intravenous, intramuscular, intraarterial, intrathecal,
intracapsular, intraorbital, intracardiac, intradermal,
intraperitoneal, transtracheal, subcutaneous, subcuticular,
intraarticular, subcapsular, subarachnoid, intraspinal, epidural
and intrasternal injection and infusion. Alternatively, a
composition of the invention can be administered via a
non-parenteral route, such as a topical, epidermal or mucosal route
of administration, for example, intranasally, orally, vaginally,
rectally, sublingually or topically. In one embodiment, the
antibodies or fragments thereof of the invention is administered by
infusion. In another embodiment, the multispecific epitope binding
protein of the invention is administered subcutaneously.
[0356] If the antibodies or fragments thereof of the invention are
administered in a controlled release or sustained release system, a
pump may be used to achieve controlled or sustained release (see
Langer, supra; Sefton, (1987) CRC Crit. Ref Biomed. Eng. 14:20;
Buchwald et al., (1980), Surgery 88:507; Saudek et al., (1989) N.
Engl. J. Med. 321:574). Polymeric materials can be used to achieve
controlled or sustained release of the therapies of the invention
(see e.g., Medical Applications of Controlled Release, Langer and
Wise (eds.), CRC Pres., Boca Raton, Fla. (1974); Controlled Drug
Bioavailability, Drug Product Design and Performance, Smolen and
Ball (eds.), Wiley, New York (1984); Ranger and Peppas, (1983) J.

Publication No. WO 99/15154; and PCT Publication No. WO 99/20253.
Examples of polymers used in sustained release formulations
include, but are not limited to, poly(2-hydroxy ethyl
methacrylate), poly(methyl methacrylate), poly(acrylic acid),
poly(ethylene-co-vinyl acetate), poly(methacrylic acid),
polyglycolides (PLG), polyanhydrides, poly(N-vinyl pyrrolidone),
poly(vinyl alcohol), polyacrylamide, poly(ethylene glycol),
polylactides (PLA), poly(lactide-co-glycolides) (PLGA), and
polyorthoesters. In one embodiment, the polymer used in a sustained
release formulation is inert, free of leachable impurities, stable
on storage, sterile, and biodegradable. A controlled or sustained
release system can be placed in proximity of the prophylactic or
therapeutic target, thus requiring only a fraction of the systemic
dose (see, e.g., Goodson, in Medical Applications of Controlled
Release, supra, vol. 2, pp. 115-138 (1984)).
[0357] Controlled release systems are discussed in the review by
Langer, (1990), Science 249:1527-1533). Any technique known to one
of skill in the art can be used to produce sustained release
formulations comprising one or more antibodies or fragments thereof
of the invention. See, e.g., U.S. Pat. No. 4,526,938, PCT

[0358] If the antibodies or fragments thereof of the invention are
administered topically, they can be formulated in the form of an
ointment, cream, transdermal patch, lotion, gel, shampoo, spray,
aerosol, solution, emulsion, or other form well-known to one of
skill in the art. See, e.g., Remington's Pharmaceutical Sciences
and Introduction to Pharmaceutical Dosage Forms, 19th ed., Mack
Pub. Co., Easton, Pa. (1995). For non-sprayable topical dosage
forms, viscous to semi-solid or solid forms comprising a carrier or
one or more excipients compatible with topical application and
having a dynamic viscosity, in some instances, greater than water
are typically employed. Suitable formulations include, without
limitation, solutions, suspensions, emulsions, creams, ointments,
powders, liniments, salves, and the like, which are, if desired,
sterilized or mixed with auxiliary agents (e.g., preservatives,
stabilizers, wetting agents, buffers, or salts) for influencing
various properties, such as, for example, osmotic pressure. Other
suitable topical dosage forms include sprayable aerosol
preparations wherein the active ingredient, in some instances, in
combination with a solid or liquid inert carrier, is packaged in a
mixture with a pressurized volatile (e.g., a gaseous propellant,
such as freon) or in a squeeze bottle. Moisturizers or humectants
can also be added to pharmaceutical compositions and dosage forms
if desired. Examples of such additional ingredients are well-known
in the art.
[0359] If the compositions comprising antibodies or fragments
thereof are administered intranasally, it can be formulated in an
aerosol form, spray, mist or in the form of drops. In particular,
prophylactic or therapeutic agents for use according to the present
invention can be conveniently delivered in the form of an aerosol
spray presentation from pressurized packs or a nebuliser, with the
use of a suitable propellant (e.g., dichlorodifluoromethane,
trichlorofluoromethane, dichlorotetrafluoroethane, carbon dioxide
or other suitable gas). In the case of a pressurized aerosol the
dosage unit may be determined by providing a valve to deliver a
metered amount. Capsules and cartridges (composed of, e.g.,
gelatin) for use in an inhaler or insufflator may be formulated
containing a powder mix of the compound and a suitable powder base
such as lactose or starch.
[0360] Methods for co-administration or treatment with a second
therapeutic agent, e.g., a cytokine, steroid, chemotherapeutic
agent, antibiotic, or radiation, are known in the art (see, e.g.,
Hardman et al., (eds.) (2001) Goodman and Gilman's The
Pharmacological Basis of Therapeutics, 10.sup.th ed., McGraw-Hill,
New York, N.Y.; Poole and Peterson (eds.) (2001)
Pharmacotherapeutics for Advanced Practice: A Practical Approach,
Lippincott, Williams & Wilkins, Phila., Pa.; Chabner and Longo
(eds.) (2001) Cancer Chemotherapy and Biotherapy, Lippincott,
Williams & Wilkins, Phila., Pa.). An effective amount of
therapeutic may decrease the symptoms by at least 10%; by at least
20%; at least about 30%; at least 40%, or at least 50%.
[0361] Additional therapies (e.g., prophylactic or therapeutic
agents), which can be administered in combination with the
antibodies or fragments thereof of the invention may be
administered less than 5 minutes apart, less than 30 minutes apart,
1 hour apart, at about 1 hour apart, at about 1 to about 2 hours
apart, at about 2 hours to about 3 hours apart, at about 3 hours to
about 4 hours apart, at about 4 hours to about 5 hours apart, at
about 5 hours to about 6 hours apart, at about 6 hours to about 7
hours apart, at about 7 hours to about 8 hours apart, at about 8
hours to about 9 hours apart, at about 9 hours to about 10 hours
apart, at about 10 hours to about 11 hours apart, at about 11 hours
to about 12 hours apart, at about 12 hours to 18 hours apart, 18
hours to 24 hours apart, 24 hours to 36 hours apart, 36 hours to 48
hours apart, 48 hours to 52 hours apart, 52 hours to 60 hours
apart, 60 hours to 72 hours apart, 72 hours to 84 hours apart, 84
hours to 96 hours apart, or 96 hours to 120 hours apart from the
antibodies or fragments thereof of the invention. The two or more
therapies may be administered within one same patient visit.
[0362] The antibodies or fragments thereof of the invention and the
other therapies may be cyclically administered. Cycling therapy
involves the administration of a first therapy (e.g., a first
prophylactic or therapeutic agent) for a period of time, followed
by the administration of a second therapy (e.g., a second
prophylactic or therapeutic agent) for a period of time,
optionally, followed by the administration of a third therapy
(e.g., prophylactic or therapeutic agent) for a period of time and
so forth, and repeating this sequential administration, i.e., the
cycle in order to reduce the development of resistance to one of
the therapies, to avoid or reduce the side effects of one of the
therapies, and/or to improve the efficacy of the therapies.
[0363] In certain embodiments, the antibodies or fragments thereof
of the invention can be formulated to ensure proper distribution in
vivo. For example, the blood-brain barrier (BBB) excludes many
highly hydrophilic compounds. To ensure that the therapeutic
compounds of the invention cross the BBB (if desired), they can be
formulated, for example, in liposomes. For methods of manufacturing
liposomes, see, e.g., U.S. Pat. Nos. 4,522,811; 5,374,548; and
5,399,331. The liposomes may comprise one or more moieties which
are selectively transported into specific cells or organs, thus
enhance targeted drug delivery (see, e.g., Ranade, (1989) J. Clin.
Pharmacol. 29:685). Exemplary targeting moieties include folate or
biotin (see, e.g., U.S. Pat. No. 5,416,016 to Low et al);
mannosides (Umezawa et al., (1988) Biochem. Biophys. Res. Commun.
153:1038); antibodies (Bloeman et al., (1995) FEBS Lett. 357:140;
Owais et al., (1995) Antimicrob. Agents Chemother. 39:180);
surfactant protein A receptor (Briscoe et al., (1995) Am. J.
Physiol. 1233:134); p 120 (Schreier et al, (1994) J. Biol. Chem.
269:9090); see also K. Keinanen; M. L. Laukkanen (1994) FEBS Lett.

[0364] The invention provides protocols for the administration of
pharmaceutical composition comprising antibodies or fragments
thereof of the invention alone or in combination with other
therapies to a subject in need thereof. The therapies (e.g.,
prophylactic or therapeutic agents) of the combination therapies of
the present invention can be administered concomitantly or
sequentially to a subject. The therapy (e.g., prophylactic or
therapeutic agents) of the combination therapies of the present
invention can also be cyclically administered. Cycling therapy
involves the administration of a first therapy (e.g., a first
prophylactic or therapeutic agent) for a period of time, followed
by the administration of a second therapy (e.g., a second
prophylactic or therapeutic agent) for a period of time and
repeating this sequential administration, i.e., the cycle, in order
to reduce the development of resistance to one of the therapies
(e.g., agents) to avoid or reduce the side effects of one of the
therapies (e.g., agents), and/or to improve, the efficacy of the
therapies.
[0365] The therapies (e.g., prophylactic or therapeutic agents) of
the combination therapies of the invention can be administered to a
subject concurrently. The term "concurrently" is not limited to the
administration of therapies (e.g., prophylactic or therapeutic
agents) at exactly the same time, but rather it is meant that a
pharmaceutical composition comprising antibodies or fragments
thereof of the invention are administered to a subject in a
sequence and within a time interval such that the antibodies of the
invention can act together with the other therapy(ies) to provide
an increased benefit than if they were administered otherwise. For
example, each therapy may be administered to a subject at the same
time or sequentially in any order at different points in time;
however, if not administered at the same time, they should be
administered sufficiently close in time so as to provide the
desired therapeutic or prophylactic effect. Each therapy can be
administered to a subject separately, in any appropriate form and
by any suitable route. In various embodiments, the therapies (e.g.,
prophylactic or therapeutic agents) are administered to a subject
less than 15 minutes, less than 30 minutes, less than 1 hour apart,
at about 1 hour apart, at about 1 hour to about 2 hours apart, at
about 2 hours to about 3 hours apart, at about 3 hours to about 4
hours apart, at about 4 hours to about 5 hours apart, at about 5
hours to about 6 hours apart, at about 6 hours to about 7 hours
apart, at about 7 hours to about 8 hours apart, at about 8 hours to
about 9 hours apart, at about 9 hours to about 10 hours apart, at
about 10 hours to about 11 hours apart, at about 11 hours to about
12 hours apart, 24 hours apart, 48 hours apart, 72 hours apart, or
1 week apart. In other embodiments, two or more therapies (e.g.,
prophylactic or therapeutic agents) are administered to a within
the same patient visit.
[0366] The prophylactic or therapeutic agents of the combination
therapies can be administered to a subject in the same
pharmaceutical composition. Alternatively, the prophylactic or
therapeutic agents of the combination therapies can be administered
concurrently to a subject in separate pharmaceutical compositions.
The prophylactic or therapeutic agents may be administered to a
subject by the same or different routes of administration.
[0367] The invention having been fully described, it is further
illustrated by the following examples and claims, which are
illustrative and are not meant to be further limiting.
EXAMPLES
Example 1: Methods, Materials and Screening for Antibodies
(i) Cell Lines
[0368] BXPC-3, SK-Br-3, BT-474, MDA-MB-453, FaDu and MCF-7 cell
lines were purchased from ATCC and routinely maintained in growth
media supplemented with 10% fetal bovine serum (FBS).
(ii) Generation of Recombinant Human, Cyno, Mouse and Rat HER3
Vectors
[0369] Murine HER3 extracellular domain was PCR amplified from
mouse brain cDNA (Clontech) and sequence verified by comparison
with Refseq NM_010153. Rat HER3 ECD was reverse transcribed from
Rat-2 cell mRNA and sequence verified by comparison with NM_017218.
Cynomolgus HER3 cDNA template was generated using RNA from various
cyno tissues (Zyagen Laboratories), and the RT-PCR product cloned
into pCR.RTM.-TOPO-XL (Invitrogen) prior to sequencing of both
strands. Human HER3 was derived from a human fetal brain cDNA
library (Source) and sequence verified by comparison with
NM_001982.
[0370] To generate tagged recombinant proteins, human, mouse, rat
and cyno HER3 was PCR amplified using Pwo Taq polymerase (Roche
Diagnostics). Amplified PCR products were gel purified and cloned
into a pDonR201 (Invitrogen) gateway entry vector that had
previously been modified to include an in-frame N-terminal CD33
leader sequence and a C-terminal TAG, e.g., FLAG TAG. The TAG
allows purification of monomeric proteins via an anti-TAG
monoclonal antibody. The target genes were flanked with AttB1 and
AttB2 allowing recombination into Gateway adapted proprietary
destination vectors (e.g., pcDNA3.1) using the Gateway.RTM. cloning
technology (Invitrogen). Recombination reactions were performed
using a Gateway LR reaction with proprietary destination vectors
containing a CMV promoter to create the TAG expression vectors,
although any commercially available vector can be used.
[0371] Further recombinant HER3 proteins were generated that fused
the HER3 ECD upstream of a C-terminal Factor X cleavage site and
the human IgG hinge and Fc domain to create an Fc-tagged protein.
To achieve this, the various HER3 ECD's were PCR amplified and
cloned into a vector (e.g., pcDNA3.1) modified to contain an
in-frame C-terminal fusion of Factor X site-Hinge-hFc. The
generated open reading frame was flanked with AttB1 and AttB2 sites
for further cloning with the Gateway.RTM. recombinant cloning
technology (Invitrogen). An LR Gateway reaction was used to
transfer HER3-Fc into a destination expression construct containing
a CMV promoter. HER3 point mutation expression constructs were
generated using standard site directed mutagenesis protocols and
the resultant vectors sequence verified.

(iii) Expression of Recombinant HER3 Proteins
[0372] The desired HER3 recombinant proteins were expressed in
HEK293 derived cell lines previously adapted to suspension culture
and grown in a Novartis proprietary serum-free medium. Small scale
expression verification was undertaken in transient 6-well-plate
transfection assays on the basis of lipofection. Large-scale
protein production via transient transfection and was performed at
the 10-20 L scale in the Wave.TM. bioreactor system (Wave Biotech).
DNA Polyethylenimine (Polysciences) was used as a plasmid carrier
at a ratio of 1:3 (w:w). The cell culture supernatants were
harvested 7-10 days post transfection and concentrated by
cross-flow filtration and diafiltration prior to purification.
(iv) Tagged Protein Purification
[0373] Recombinant tagged HER3 proteins (e.g., TAG-HER3) were
purified by collecting the cell culture supernatant and
concentrating 10-fold by cross-flow filtration with a 10 kDa cut
off filter (Fresenius). An anti-TAG column was prepared by coupling
an anti-TAG monoclonal antibody to CNBr activated Sepharose 4B at a
final ratio of 10 mg antibody per mL of resin. Concentrated
supernatant was applied to a 35 ml anti-Tag column at a flow rate
of 1-2 mL/minute. After base-line washing with PBS, bound material
was eluted with 100 mM glycine (pH 2.7), neutralized and sterile
filtered. Protein concentrations were determined by measuring the
absorbance at 280 nm and converting using a theoretical factor of
0.66 AU/mg. The purified protein was finally characterized by
SDS-PAGE, N-terminal sequencing and LCMS.
(v) Fc Tag Purification
[0374] Concentrated cell culture supernatant was applied to a 50 ml
Protein A Sepharose Fast Flow column at a flow rate of 1 ml/min.
After baseline washing with PBS, the column was washed with 10
column volumes of 10 mM NaH.sub.2PO.sub.4/30% (v/v) Isopropanol, pH
7.3 followed by 5 column volumes of PBS. Finally, bound material
was eluted with 50 mM Citrate/140 mM NaCl (pH 2.7), neutralized and
sterile filtered.
(vi) Generation of Over-Expressing Cell Lines
[0375] To generate a cell line that expresses high levels of HER3
on the cell surface, a mammalian expression vector was constructed
containing an insert coding for a CD33 leader sequence upstream of
amino acid residues 20-667 of human HER3 fused in-frame to amino
acid residues 669-1210 of human EGFR. When expressed in mammalian
cells the resultant chimeric protein contains an N-terminal HER3
extracellular and transmembrane domain and a C-terminal EGFR
cytoplasmic domain. The HER3/1 vector was transfected into CHO-S
cells (Invitrogen) and stable pools generated following antibiotic
selection. The resultant cell line (CHO HER3/1) expressed high
levels of HER3 extracellular domain on its cell surface.
(vii) HuCAL GOLD.RTM. Pannings
[0376] For the selection of antibodies recognizing human HER3
multiple panning strategies were employed. Therapeutic antibodies
against human HER3 protein were generated by selection of clones
having high binding affinities, using as the source of antibody
variant proteins a commercially available phage display library,
the MorphoSys HuCAL GOLD.RTM. library. The phagemid library is
based on the HuCAL.RTM. concept (Knappik et al., (2000) J Mol Biol
296:57-86) and employs the CysDisplay.RTM. technology for
displaying the Fab on the phage surface (WO01/05950 to
Lohning).
[0377] For the isolation of anti-HER3 antibodies, standard as well
as RapMAT panning strategies were performed using solid phase,
solution, whole cell and differential whole cell panning
approaches.
(viii) Solid Phase Panning
[0378] To identify anti-HER3 antibodies a variety of solid phase
panning strategies were performed using differing recombinant HER3
proteins. To perform each round of solid phase panning, Maxisorp
plates (Nunc) were coated with HER3 protein. Tagged proteins were
either captured using plates previously coated with anti-Fc (goat
or mouse anti-human IgG, Jackson Immuno Research), anti-Tag
antibody or via passive adsorption. The coated plates were washed
with PBS and blocked. Coated plates were washed twice with PBS
prior to the addition of HuCAL GOLD.RTM. phage-antibodies for 2
hours at room temperature on a shaker. Bound phages were eluted
were added to E. coli TG-land incubated for phage infection.
Subsequently infected bacteria were isolated and plated on agar
plates. Colonies were scraped off the plates and phages were
rescued and amplified. Each HER3 panning strategy comprised of
individual rounds of panning and contained unique antigens, antigen
concentrations and washing stringency.
(ix) Solution Phase Panning
[0379] Each round of solution phase panning was performed using
various biotinylated recombinant HER3 proteins in the presence or
absence of neuregulin 1431 (R&D Systems). Proteins were
biotinylated using the EZ-link sulfo-NHS-LC biotinylation kit
(Pierce) according to the manufacturers instructions. 800 .mu.l of
Streptavidin linked magnetic beads (Dynabeads, Dynal) were washed
once with PBS and blocked overnight with Chemiblocker (Chemicon).
HuCAL GOLD.RTM. phage-antibodies and the appropriate biotinylated
HER3 were incubated in a reaction tube. Streptavidin magnetic beads
were added for 20 minutes and were collected with a magnetic
particle separator (Dynal). Bound phages were eluted from the
Dynabeads by adding DTT containing buffer to each tube and added to
E. coli TG-1. Phage infection was performed in an identical manner
to that described in solid phase panning. Each HER3 panning
strategy comprised of individual rounds of panning and contained
unique antigens, antigen concentrations and washing stringency.
(x) Cell Based Panning
[0380] For cell pannings, HuCAL GOLD.RTM. phage-antibodies were
incubated with approximately 10.sup.7 cells on a rotator for 2
hours at room temperature, followed by centrifugation. The cell
pellet was isolated phages were eluted from the cells The
supernatant was collected and added to E. coli TG-1 culture
continued by the process described above. Two cell based strategies
were employed to identify anti-HER3 antibodies: [0381] a) Whole
cell panning: In this strategy a variety of intact cell lines were
used as the antigens. [0382] b) Differential whole cell panning: In
this strategy the antigens sequentially consisted of cells and
recombinant HER3 proteins (see 1981.09 as an example). The cell
based pannings were performed as described above whilst solid phase
panning protocols were employed when recombinant proteins were
utilized as antigens. The washes were conducted using PBS
(2-3.times.) and PBST (2-3.times.).
(xi) RapMAT.TM. Library Generation and Pannings
[0383] In order to increase antibody binding affinity whilst
maintaining library diversity the second round output of both
solution and solid phase pannings were entered into the RapMAT.TM.
process whilst the third round output of the whole cell and
differential whole cell panning strategies were entered (Prassler
et al., (2009) Immunotherapy; 1: 571-583. RapMAT.TM. libraries were
generated by sub-cloning Fab-encoding inserts of phages selected
via panning into the display vector pMORPH.RTM.25_bla_LHCand were
further digested to either generate H-CDR2 RapMAT.TM. libraries and
L-CDR3 RapMAT.TM. libraries by using specific restriction enzymes.
The inserts were replaced with TRIM maturation cassettes (Virnekas
et al., (1994) Nucleic Acids Research 22:5600-5607) for H-CDR2 or
L-CDR3 according to pool composition. Library sizes were estimated
to range between 8.times.10.sup.6-1.times.10.sup.8 clones. RapMAT
antibody-phage were produced and subjected to two further rounds of
solution, solid phase or cell based panning using the experimental
methods described previously.
Example 2: Transient Expression of Anti-HER3 IgG's
[0384] Suspension adapted HEK293-6E cells were cultivated in a
BioWave20 to a density of approximately 2.times.10.sup.6 viable
cells/mL. The cells were transiently transfected with the relevant
sterile DNA: PEI-MIX and further cultivated. Seven days after
transfection, cells were removed by crossflow filtration using
Fresenius filters (0.2 .mu.m). The cell free material was
concentrated with crossflow filtration using a 10 kDa cut off
filter (Fresenius) and the concentrate was sterile filtered through
a stericup filter (0.22 .mu.m). The sterile supernatant was stored
at 4.degree. C.
Example 3: Purification of Anti-HER3 IgG
[0385] The purification of IgG was performed on a AKTA 100 explorer
Air chromatography system at 6.degree. C. in a cooling cabinet,
using a XK16/20 column with 25 mL of self-packed MabSelect SuRe
resin (all GE Healthcare). All flow rates were 3.5 mL/min, except
for loading, at a pressure limit of 5 bar. The column was
equilibrated with 3 column volumes of PBS prior to loading the
filtered fermentation supernatant at 2.0 mL/min. The column was
washed with 8 column volumes of PBS. IgG was eluted with a pH
gradient, starting at 50 mM citrate/70 mM NaCl (pH 4.5), going
linearly down in 12 Column volumes to 50 mM citrate/70 mM NaCl (pH
2.5), followed by a 2 column volume constant step of the same pH
2.5 buffer. The IgG containing fractions were pooled and
immediately neutralized and sterile filtered (Millipore Steriflip,
0.22 um). OD.sub.280 was measured and the protein concentration
calculated based on the sequence data. The pools were separately
tested for aggregation (SEC-MALS) and purity (SDS-PAGE and MS).
Example 4: Expression and Purification of HuCAL.RTM.-Fab Antibodies
in E. coli
[0386] Expression of Fab fragments encoded by pMORPH.RTM. X9_Fab_MH
in TG-1 cells was carried out in shaker flask cultures using 500 mL
of 2.times.YT medium supplemented with 34 .mu.g/mL chloramphenicol.
Cultures were shaken at 30.degree. C. until the OD600 nm reached
0.5. Expression was induced by addition of 0.75 mM IPTG (isopropyl-
-D-thiogalactopyranoside) for 20 hours at 30.degree. C. Cells were
disrupted using lysozyme. His6-tagged ("His6" disclosed as SEQ ID
NO: 495) Fab fragments were isolated via IMAC (Bio-Rad). Buffer
exchange to 1.times.Dulbecco's PBS (pH 7.2) was performed using
PD10 columns. Samples were sterile filtered (0.2 .mu.m). Protein
concentrations were determined by UV-spectrophotometry. The purity
of the samples was analyzed in denaturing, reducing 15% SDS-PAGE.
The homogeneity of Fab preparations was determined in native state
by size exclusion chromatography (HP-SEC) with calibration
standards
Example 5: HER3 Antibody Affinity (K.sub.D) Measurements by
Solution Equilibrium Titration (SET)
[0387] Affinity determination in solution was essentially performed
as previously described (Friguet et al., (1985) J Immunol Methods
77:305-19). In order to improve the sensitivity and accuracy of the
SET method, it was transferred from classical ELISA to ECL based
technology (Haenel et al., (2005) Anal biochem 339:182-84).
[0388] Unlabeled HER3-Tag (human, rat, mouse or cyno) described
previously was used for affinity determination by SET.
[0389] The data was evaluated with XLfit software (ID Business
Solutions) applying customized fitting models. For K.sub.D
determination of each IgG the following model was used (modified
according to Piehler, et al (Piehler et al., (1997) J Immunol
Methods 201:189-206).
y = 2 B max [ IgG ] ( [ IgG ] 2 - ( x + [ IgG ] + K D 2 - ( x + [
IgG ] + K D ) 2 4 - x [ IgG ] ) 2 2 [ IgG ] ) ##EQU00001##
[0390] [IgG]: applied total IgG concentration
[0391] x: applied total soluble antigen concentration (binding
sites)
[0392] B.sub.max: maximal signal of IgG without antigen
[0393] K.sub.D: affinity
Example 6: Antibody Cell Binding Determination by FACS
[0394] The binding of antibodies to endogenous human antigen
expressed on human cancer cells was accessed by FACS. In order to
determine antibody EC.sub.50 values SK-Br-3 cells were harvested
with accutase and diluted to 1.times.10.sup.6 cells/mL in FACS
buffer (PBS/3% FBS/0.2% NaN.sub.3). 1.times.10.sup.5 cells/well
were added to each well of a 96-well plate (Nunc) and centrifuged
at 210 g for 5 minutes at 4.degree. C. before removing the
supernatant. Serial dilutions of test antibodies (diluted in 1:4
dilution steps with FACS buffer) were added to the pelleted cells
and incubated for 1 hour on ice. The cells were washed and pelleted
three times with 100 .mu.L FACS buffer. PE conjugated goat
anti-human IgG (Jackson ImmunoResearch) diluted 1/200 with FACS
buffer were added to the cells and incubated on ice for 1 hour.
Additional washing steps were performed three times with 100 .mu.L
FACS buffer followed by centrifugation steps at 210 g for 5 minutes
at 4.degree. C. Finally, cells were resuspended in 200 .mu.L FACS
buffer and fluorescence values were measured with a FACSArray (BD
Biosciences). The amount of cell surface bound anti-HER3 antibody
was assessed by measuring the mean channel fluorescence.
Example 7: HER3 Domain and Mutant Binding
[0395] 96-well Maxisorp plates (Nunc) were coated overnight at
4.degree. C. with 200 ng of the appropriate recombinant human
protein (HER3-Tag, D1-2-Tag, D2-Tag, D3-4-Tag, D4-Tag, HER3
K267A-Tag, HER3 L268A-Tag, HER3 K267A/L268A and a tagged irrelevant
control). All wells were then washed three times with PBS/0.1%
Tween-20, blocked for one hour with PBS/1% BSA/0.1% Tween-20 and
washed three times with PBS/0.1% Tween-20. Anti-HER3 antibodies
were added to the relevant wells up to a final concentration of 10
.mu.g/mL were added to the appropriate wells and incubated at room
temperature for two hours. Plates were washed three times with
PBS/0.1% Tween-20 prior to the addition of the appropriate
peroxidase linked detection antibody diluted 1/10000 in PBS/1%
BSA/0.1% Tween-20. The detection antibodies used were goat
anti-mouse (Pierce, 31432), rabbit anti-goat (Pierce, 31402) and
goat anti-human (Pierce, 31412). Plates were incubated at room
temperature for one hour before washing three times with PBS/0.1%
Tween-20. 100 .mu.l TMB (3,3', 5,5' tetramethyl benzidine)
substrate solution (BioFx) was added to all wells for 6 minutes
before stopping the reaction with 50 .mu.l 2.5% H.sub.2SO.sub.4.
The extent of HER3 antibody binding to each recombinant protein was
determined by measuring the OD.sub.450 using a SpectraMax plate
reader (Molecular Devices). Where appropriate, dose response curves
were analyzed using Graphpad Prism.
Example 8: HER3 Epitope Mapping Using Hydrogen/Deuterium Exchange
Mass Spectrometry
Materials
[0396] D.sub.2O buffer was made by dissolving 25 mM TBS (pH
7.5)/500 mM NaCl in heavy water (Sigma). The reduction solution was
50 mM formate buffer (pH 4) 500 mM TCEP and the quenching solution
0.5% (v/v) trifluoroacetic acid (TFA) in water. Buffer A was 0.25%
formic acid/10% methanol/10% ethylene glycol in water, and buffer B
was 0.25% formic acid in acetonitrile. All chemicals were purchased
from Sigma, and HPLC grade solvents were from Fisher
Scientific.
Liquid Handling and Chromatography
[0397] Automated hydrogen-deuterium exchange mass spectrometry (HDX
MS) experiments were designed based upon methods and equipment
described by Wales et al., (2006) Anal. Chem. 78:1005-1014). In
short, all liquid handling operations used a Pal HTS liquid-handler
(LEAP Technologies) housed in a refrigerated enclosure maintained
at 2.degree. C. A 6-port injection valve and a wash station were
mounted on the liquid-handler rail and facilitated sample injection
into the chromatographic system and syringe washing. The
chromatographic system, consisted of an additional 10-port valve, a
2.1 mm.times.30 mm Poroszyme pepsin column (Applied Biosystems), a
reverse-phase 0.5 mm.times.2 mm Cap Trap cartridge (Michrom
Bioresources), and a self-packed electrospray emitter as analytical
column (100 .mu.m.times..about.60 mm, Kinetex 2.6 .mu.m C18,
Phenomenex). The 10-port valve head, the trap cartridge and the
analytical column were housed in a separate enclosure constructed
from aluminum and maintained at -5.degree. C. by peltier stacks.
Valves and columns were configured in such a way as to allow
in-line protein digestion, peptide desalting, and reversed-phase
chromatography prior to introduction of the sample into the
electrospray ionization (ESI) source of the mass spectrometer
(LTQ-Orbitrap, Thermo Scientific).
[0398] The fluid streams required for operation were provided by
two separate HPLC pumps. The first HPLC (Surveyor MS pump, Thermo
Scientific) delivered buffer A at a constant flow rate of 125
.mu.L/min and was used to transfer sample through the immobilized
pepsin cartridge onto the reversed-phase trap cartridge mounted
across the 10-port valve. After the loading and desalting period,
the 10-port valve was switched to elute the sample with the help of
a gradient pump (AQUITY UPLC, Waters) from the reversed-phase trap
cartridge, through the analytical column and into the ion source of
the mass spectrometer. The immobilized enzyme cartridge was
isolated to waste during gradient elution. The gradient pump
delivered linear gradient segments of 0 to 40% mobile phase B over
35 minutes at 5 .mu.L/min and 40 to 95% mobile phase B at 5
.mu.L/min over 10 minutes. The gradient flow from the pump was
split at the 10-port valve using a passive splitter so that the
actual flow through the trap cartridge and analytical column for
gradient elution was .about.1 .mu.L/min. The entire chromatographic
run was 70 minutes long including washing and equilibration
steps.
Mass Spectrometry
[0399] For the purpose of identification of proteolytic fragments
resulting from online digestion several data-dependent MS/MS
experiments were performed. For these acquisitions, tandem MS
spectra were acquired with the LTQ analyzer of the LTQ-Orbitrap
hybrid mass spectrometer. Precursor mass selection was based on MS
scans acquired by the Orbitrap analyzer. Single stage MS
acquisitions performed for the purpose of deuteration level
determination were acquired at a resolution of 60,000 by the
Orbitrap (over m/z 400-2000) analyzer.
Preparation of Protein and Protein:Fab Complexes
[0400] HER3 protein was prepared by diluting 50 .mu.g HER3-Tag with
25 mM TBS (pH 7.5)/500 mM NaCl to yield a final volume of 50 .mu.L.
Protein:Fab complexes were prepared by mixing 50 .mu.g HER3-Tag in
a 1:1 molar ratio with the Fab's studied. Protein:Fab mixtures were
then diluted to a final volume of 50 .mu.L with 25 mM TBS (pH
7.5)/500 mM NaCl.
[0401] Protein:Fab complexes were prepared and allowed to incubate
for at least 2 hours at 4.degree. C. Four 96-well plates containing
sample, diluent, quench, and reduction solutions were loaded into
the liquid-handler before the start of each experimental. For
on-exchange experiments 50 .mu.L of HER3 or HER3:Fab complex was
diluted with 150 .mu.L D.sub.2O buffer. The mixture was reduced by
adding 200 .mu.L reduction buffer for 1 minute before quenching
with 600 .mu.L of quench buffer. The total volume after all liquid
handling steps was .about.1 mL. Once mixed, the quenched solution
was injected into the chromatographic system where it was
automatically digested, separated and analyzed by LCMS. The average
change in deuteration between sample and control was calculated as
the difference between the deuterium uptake levels of the sample
and control.
Data Processing
[0402] The Orbitrap RAW files were converted into mzXML files using
an in-house program (RawXtract). Subsequently, tandem MS
acquisitions were searched using SEQUEST (Yates Lab, Scripps
Research Institute, La Jolla, Calif.) and search results were
automatically filtered using DTASelect 2.0 (Yates Lab, Scripps
Research Institute, La Jolla, Calif.). Using the peptide sequence
identifications, an in-house written program was used to
automatically extract single-ion chromatograms for each identified
sequence and generate average spectra across the chromatographic
peak. Average spectra were smoothed and centroided. The level of
deuterium uptake was taken as the difference in mass between a
deuterated sample and non-deuterated reference. Processed data was
manually validated and adjusted to correct inaccuracies and errors
from automated processing steps. Deuterium uptake levels were
assigned to each residue of the protein sequence by delocalizing
the deuterium content across each peptide (i.e., dividing the
observed deuteration level by the number of amino acids in that
peptide). If a residue was covered by more than one peptide, the
normalized deuterium uptakes of all peptides covering that residue
were averaged.
Example 9: X-Ray Crystallographic Structure Determination of the
Human HER3/MOR09823 Fab and Human HER3/MOR09825 Fab Complexes
[0403] The present example presents the crystal structure of full
length HER3 bound to the Fab fragment of MOR09823 and the Fab
fragment of MOR09825, determined at 3.2 .ANG. and 3.4 .ANG.
resolution, respectively. Tagged human HER3 was further purified on
a HiLoad 26/60 Superdex 200 PrepGrade column (GE Healthcare)
equilibrated in PBS (pH 7.3). E. coli expressed MOR09823 and
MOR09825 Fabs were isolated by lysing cells with lysozyme and
His6-tagged ("His.sub.6" disclosed as SEQ ID NO: 495) Fab fragments
were captured on a HisTrap_HP (GE Healthcare) column. MOR09823
Fab-fragments were further purified by gel filtration
chromatography using a Superdex 75 16/60 column (GE Healthcare)
equilibrated in 25 mM Tris (pH 7.5), 150 mM NaCl.
[0404] HER3 Fab complexes were prepared by mixing excess Fab with
tagged HER3 in a molar ratios of 1.3-1.8:1 (concentration estimated
by absorbance at 280 nm using calculated extinction coefficients of
0.9 and 1.4 (mg/ml).sup.-1 cm.sup.-1 for HER3 and Fab,
respectively) and purifying the complexes on a Superdex 200 10/300
column (GE Healthcare) equilibrated in 25 mM Tris (pH 7.5), 150 mM
NaCl. Peak fractions were analyzed by SDS-PAGE and LCMS. For each
complex, fractions containing both HER3 and Fab in an approximate
equimolar ratio were pooled and concentrated. HER3/MOR09823
crystals were grown at 293K by sitting drop vapor diffusion from
drops containing 150 nl HER3/MOR09823 complex and 150 nl of
reservoir solution (100 mM sodium citrate pH 5.6, 20% PEG 4000 and
20% isopropanol). Crystals were transferred to reservoir solution
containing additional 8% glycerol and flash cooled in liquid
nitrogen. HER3/MOR09825 crystals were grown at 293K by sitting drop
vapor diffusion from drops containing 150 nl HER3/MOR09825 complex
and 150 nl of reservoir solution (100 mM bis-tris pH 6.5, 16% PEG
10,000). Crystals were transferred to 100 mM bis-tris pH 6.5, 18%
PEG 10,000 and 22% glycerol and flash cooled in liquid
nitrogen.
[0405] Data were collected at beamline 17-ID at the Advanced Photon
Source (Argonne National Laboratory). HER3/MOR09823 Fab complex
data were processed and scaled at 3.2 .ANG. using HKL2000 (HKL
Research Inc) in space group 1222 with cell dimensions a=124.16,
b=139.44, c=180.25 .ANG., with good statistics. The HER3/MOR09823
Fab structure was solved by molecular replacement using Phaser
(McCoy et al., (2007) J. Appl. Cryst. 40:658-674) with fragments of
a Fab and the published HER3 ECD structure 1mb6 as search models.
The final model, which contains 1 molecule of the HER3/MOR09823 Fab
complex per asymmetric unit, was built in COOT (Emsley & Cowtan
(2004) Acta Cryst. 60:2126-2132) and refined to R and R.sub.free
values of 19.0 and 24.5%, respectively, with an rmsd of 0.010 .ANG.
and 1.37.degree. for bond lengths and bond angles, respectively,
using BUSTER (Global Phasing, LTD). Residues of HER3 that contain
atoms within 5 .ANG. of any atom in MOR09823 Fab as identified in
PyMOL (Schrodinger, LLC) are listed in Tables 11 and 12.
HER3/MOR09825 Fab complex data were processed and scaled at 3.4
.ANG. using autoPROC (Global Phasing, LTD) in space group 1222 with
cell dimensions a=124.23, b=140.94, c=180.25 .ANG., with good
statistics. The HER3/MOR09825 Fab structure was solved by molecular
replacement using Phaser (McCoy et al., (2007) J. Appl. Cryst.
40:658-674) with the HER3/MOR09823 Fab structure as a search model.
The final model, which contains 1 molecule of the HER3/MOR09825 Fab
complex per asymmetric unit, was built in COOT (Emsley & Cowtan
(2004) Acta Cryst. 60:2126-2132) and refined to R and R.sub.free
values of 18.8 and 24.9%, respectively, with an rmsd of 0.009 .ANG.
and 1.21.degree. for bond lengths and bond angles, respectively,
using BUSTER (Global Phasing, LTD). Residues of HER3 that contain
atoms within 5 .ANG. of any atom in MOR09825 Fab as identified in
PyMOL (Schrodinger, LLC) are listed in Tables 13 and 14.

Systems) prepared in 1% BSA/1.times. Tris/0.1% Tween-20 by
incubating with shaking at room temperature for 1 hour. The wells
were washed four times with 1.times. Tris/0.1% Tween-20 and
biotinylated proteins were detected by incubating with S-Tag
labelled Streptavidin (Mesoscale Discovery) diluted in 1%
BSA/1.times. Tris/0.1% Tween-20 for one hour at room temperature.
Each well was aspirated and washed four times with 1.times.
Tris/0.1% Tween-20 before adding 20 .mu.L of Read buffer T with
surfactant (Mesoscale Discovery) and the signal quantified using a
Mesoscale Sector Imager. Antibodies MOR06391 or MOR03207 were
included in signalling experiments as isotype controls.
Example 11: Phospho-Akt (S473) In Vitro Cell Assays
[0408] Sub-confluent SK-Br-3 and BT-474 cells grown in complete
media were harvested with accutase (PAA Laboratories) and
resuspended in the appropriate growth media at a final
concentration of 5.times.10.sup.5 cells/mL. 100 .mu.L of cell

NP-40/1 mM sodium orthovanadate/Aprotinin (10 .mu.g/mL)/Leupeptin
(10 .mu.g/mL)) and incubated on ice with shaking for 30 minutes.
Lysates were then collected and spun at 1800 g for 15 minutes at
4.degree. C. to remove cell debris. 20 .mu.L of lysate was added to
a multi-spot 384-well Phospho-Akt carbon plate (Mesoscale
Discovery) that had previously been blocked with 3% BSA/1.times.
Tris/0.1% Tween-20. The plate was incubated at room temperature for
two hours with shaking before the lysate was aspirated and the
wells washed four times with 1.times. Tris buffer (Mesoscale
Discovery)/0.1% Tween-20. Phosphorylated Akt was detected using 20

Example 12: Cell-Line Proliferation Assays
[0409] SK-Br-3 cells were routinely cultured in McCoy's 5 .ANG.
medium modified, supplemented with 10% fetal bovine serum and
BT-474 cells were cultured in DMEM supplemented with 10% FBS.
Sub-confluent cells were trypsinized, washed with PBS, diluted to
5.times.10.sup.4 cells/mL with growth media and plated in 96-well
clear bottom black plates (Costar 3904) at a density of 5000
cells/well. The cells were incubated overnight at 37.degree. C.
before adding the appropriate concentration of HER3 antibody
(typical final concentrations of 10 or 1 .mu.g/mL). The plates were
returned to the incubator for 6 days before assessing cell
viability using CellTiter-Glo (Promega). 100 .mu.L of CellTiter-Glo
solution was added to each well and incubated at room temperature
with gentle shaking for 10 minutes. The amount of luminescence was
determined using a SpectraMax plate reader (Molecular Devices). The
extent of growth inhibition obtained with each antibody was
calculated by comparing the luminescence values obtained with each
HER3 antibody to a standard isotype control antibody
(MOR06391).
[0410] For proliferation assays MCF-7 cells were routinely cultured
in DMEM/F12 (1:1) containing 4 mM L-Glutamine/15 mM HEPES/10% FBS.
Sub-confluent cells were trypsinized, washed with PBS and diluted
to 1.times.10.sup.5 cells/mL with DMEM/F12 (1:1) containing 4 mM
L-Glutamine/15 mM HEPES/10 .mu.g/mL Human Transferrin/0.2% BSA.
Cells were plated in 96-well clear bottom black plates (Costar) at
a density of 5000 cells/well. The appropriate concentration of HER3
antibody (typical final concentrations of 10 or 1 .mu.g/mL) was
then added. 10 ng/mL of NRG1-.beta.1 EGF domain (R&D Systems)
was also added to the appropriate wells to stimulate cell growth.
The plates were returned to the incubator for 6 days before
assessing cell viability using CellTiter-Glo (Promega). The extent
of growth inhibition obtained with each antibody was calculated by
subtracting the background (no neuregulin) luminescence values and
comparing the resulting values obtained with each anti-HER3
antibody to a standard isotype control antibody (MOR06391).
Example 13: Ligand Blocking Cell Assays
[0411] MCF-7 cells cultured in MEM supplemented with 10% FBS and 1
.mu.g/mL insulin (Sigma) were rinsed and collected in a small
volume of FACSmax cell dissociation buffer (Genlantis) prior to the
addition of 5 mL of FACS buffer (PBS/1% FBS/0.1% sodium azide). The
cell density was counted and adjusted to a final concentration of
1.times.10.sup.6 cells/mL. 100 .mu.l of cell suspension was added
to each well of a 96-well plate and the cells pelleted via
centrifugation (220 g, 3 minutes, 4.degree. C.). Cell pellets were
resuspended in 100 .mu.L of the appropriate test antibodies diluted
in FACS buffer (typical final antibody concentrations ranged from
100 to 0.1 nM) and the plate incubated on ice for 45 minutes. The
ligand blocking antibody MAB3481 (R&D Systems) was included as
a positive control. Cells were washed twice with staining buffer
prior to adding 10 nM NRG1-.beta.1 EGF domain (R&D Systems)
diluted in FACS buffer and incubating on ice for 45 minutes. Cells
were washed twice with staining buffer and bound neuregulin
detected by incubating the cells with 10 nM anti-human NRG1-131 EGF
domain antibody (R&D Systems) on ice for 45 minutes. Cells were
washed twice with staining buffer and incubated on ice for 45
minutes with PE-linked anti-goat antibody (Jackson ImmunoResearch)
diluted 1/500 with FACS buffer. Cells were then pelleted via
centrifugation and the pellet resuspended in 200 .mu.L FACS buffer.
To quantify each sample 10,000 live cells were counted on a LSR II
Flow Cytometer (BD Biosciences) and the amount of cell surface
bound neuregulin was assessed by measuring the mean channel
fluorescence.
Example 14: Ligand Blocking Biochemical Assay
[0412] The present method includes utility of a Surface plasmon
resonance (SPR)-based biosensor (Biacore.TM. GE Healthcare,
Uppsala, Sweden) to examine the ability of HER3/antibody complexes
to bind neuregulin.
[0413] Biacore.TM. utilizes the phenomenon of surface plasmon
resonance (SPR) to detect and measure binding interactions. In a
typical Biacore experiment, one of the interacting molecules
(neuregulin) is immobilized on a matrix while the interacting
partner (HER3) is flowed over the surface. A binding interaction
results in an increase in mass on the sensor surface and a
corresponding direct change in the refractive index of the medium
in the vicinity of the sensor surface. Changes in refractive index
or signal are recorded in resonance units (R.U.) Signal changes due
to association and dissociation of complexes are monitored in a
non-invasive manner, continuously and in real-time, the results of
which are reported in the form of a sensorgram.
[0414] Biacore.TM. T100 (GE Healthcare, Uppsala, Sweden) was used
to conduct all experiments reported herein. Sensor surface
preparation and interaction analyses were performed at 25.degree.
C. Buffer and Biacore reagents were purchased from GE Healthcare.
Running buffer containing 10 mM Hepes, pH7.4/150 mM NaCl, 0.05%
P20, 0.5% BSA was utilized throughout the assay.
[0415] NRG-1.beta.1 extracellular domain (R&D Systems) was
incubated on ice for 45 minutes with EZ-link Sulfo-NHS-LC-LC-Biotin
(Pierce) at a molar ratio of 5:1. The reaction was quenched via the
addition excess ethanolamine and uncoupled biotin removed from the
biotinylated-NRG using desalt spin columns (Zeba). Biotinylated-NRG
was captured onto a sensor chip CAP pre-immobilized with
approximately 3000 R.U. of ssDNA-streptavidin (Biotin CAPture kit)
to yield neuregulin surface densities in the range 400-600 R.U. A
reference flowcell was generated by omitting biotinylated-NRG from
the injection steps such that only ssDNA-streptavidin was present
on the flowcell surface.
[0416] HER3/antibody complexes were generated by incubating 10 nM
human HER3-Fc with increasing concentrations (0-50 nM) of the
appropriate test antibody for 15 minutes at room temperature prior
to incubating in the Biacore.TM. at 10.degree. C. Interaction
analyses were performed by injecting HER3/antibody complexes over
reference and neuregulin surfaces in series for 180 seconds at a
flow-rate of 60 .mu.L/min. Complex dissociation was monitored for
180 seconds at a flow rate of 60 .mu.L/min. Surface regeneration
was performed at the end of each analysis cycle using a 120 second
injection of 8M guanidine: 1M NaOH (3:1) followed by a 120 second
injection of 30% acetonitrile/0.25M NaOH at a flow rate of 30
.mu.L/min.
Example 15: In Vivo PD Studies
[0417] BxPC3 and BT-474 cells were cultured and implanted in female
athymic nu/nu Balb/C mice (Harlan Laboratories) as described in
Examples 16 and 17.
[0418] Once tumors had reached an appropriate size, animals were
examined for tumor quality. Animals with ulcerated tumors or animal
with fluid-filled tumors were excluded from the study. The
remaining animals were dosed intravenously with antibody via
lateral tail vein injection. At the given time points, animals were
euthanized via CO.sub.2 asphyxiation and whole blood was collected
via cardiac puncture and placed into a 1.5 mL Eppendorf collection
tube. Tumor tissue was immediately dissected, placed into a
screw-top polypropylene sample tube and snap frozen in liquid
nitrogen. Tissue was stored at -80.degree. C. until lysates were
prepared.
Example 16: In Vivo BT-474 Efficacy Studies
[0419] BT-474 cells were cultured in DMEM containing 10%
heat-inactivated fetal bovine serum without antibiotics until the
time of implantation.
[0420] One day before cell inoculation, female athymic nu/nu Balb/C
mice (Harlan Laboratories) were implanted subcutaneously with a
sustained release 17.beta.-estradiol pellet (Innovative Research of
America) to maintain serum estrogen levels. One day after
17.beta.-estradiol pellet implantation, 5.times.10.sup.6 cells were
injected orthotopically into the 4.sup.th mammary fatpad in a
suspension containing 50% phenol red-free matrigel (BD Biosciences)
in Hank's balanced salt solution. The total injection volume
containing cells in suspension was 200 .mu.L. 20 days following
cell implantation animals with a tumor volume of approximately 200
mm.sup.3 were enrolled in the efficacy study. In general, a total
of 10 animals per group were enrolled in efficacy studies.
[0421] For single-agent studies, animals were dosed intravenously
via lateral tail vein injection with either MOR10701 or MOR10703.
An initial loading dose of 40 mg/kg was given for the first dose.
After the initial dose, animals were on a 20 mg/kg, every other day
schedule for the duration of the study. For combination studies,
animals were dosed with either MOR10701 or MOR10703 (20 mg/kg, iv,
q2d) and a sub-optimal dose of trastuzumab (1 mg/kg, iv, 2qw).
[0422] For the duration of the studies, tumor volume was measured
by calipering twice per week. Percent treatment/control (T/C)
values were calculated using the following formula:
% T/C=100.times..DELTA.T/.DELTA.C if .DELTA.T>0
[0423] where:
[0424] T=mean tumor volume of the drug-treated group on the final
day of the study;
[0425] .DELTA.T=mean tumor volume of the drug-treated group on the
final day of the study-mean tumor volume of the drug-treated group
on initial day of dosing;
[0426] C=mean tumor volume of the control group on the final day of
the study; and
[0427] .DELTA.C=mean tumor volume of the control group on the final
day of the study-mean tumor volume of the control group on initial
day of dosing.
[0428] Body weight was measured twice per week and dose was body
weight adjusted. The % change in body weight was calculated as
(BW.sub.current-BW.sub.initial)/(BW.sub.initial).times.100. Data is
presented as percent body weight change from the day of treatment
initiation.
[0429] All data were expressed as mean.+-.standard error of the
mean (SEM). Delta tumor volume and body weight were used for
statistical analysis. Between groups comparisons were carried out
using a one-way ANOVA followed by a post hoc Tukey. For all
statistical evaluations the level of significance was set at
p<0.05. Significance compared to the vehicle control group is
reported.
Example 17: In Vivo BxPC3 Efficacy Studies
[0430] BxPC3 cells were cultured in RPMI-1640 medium containing 10%
heat-inactivated fetal bovine serum without antibiotics until the
time of implantation.
[0431] Female athymic nu/nu Balb/C mice (Harlan Laboratories) were
implanted subcutaneously with 10.times.10.sup.6 cells in a mixture
of 50% phosphate buffered saline with 50% matrigel. The total
injection volume containing cells in suspension was 200 .mu.L. Once
tumors had reached approximately 200 mm.sup.3 in size, animals were
enrolled in the efficacy study. In general, a total of 10 animals
per group were enrolled in studies. Animals were excluded from
enrollment if they exhibited unusual tumor growth characteristics
prior to enrollment.
[0432] Animals were dosed intravenously via lateral tail vein
injection. An initial loading dose of 40 mg/kg was given for the
first dose. After the initial dose, animals were on a 20 mg/kg,
every other day schedule for the duration of the study (25 days
under treatment). Tumor volume and T/C values were calculated as
previously detailed.
Example 18: Phospho-Akt (S473) In Vivo PD Assays
[0433] Approximately 50 mm.sup.3 frozen tumor (e.g. BT-474 or
BXPC-3) tissue was thawed on ice and 100-300 .mu.L of T-PER buffer
(Pierce) containing phosphatase (Roche) and protease inhibitors
(Roche) was added to each sample. The volume of lysis buffer added
was dependent upon the size of the tumor sample. The tissue was
broken down using a 1.5 mL pestle (Fisher Scientific) and the
resultant suspensions were incubated on ice for 15 minutes before
being frozen overnight at -80.degree. C. Samples were thawed and
spun for 15 minutes at 13000 g, 4.degree. C. prior to quantifying
the supernatant protein concentration by BCA assay (Thermo
Scientific). Tissue supernatants were diluted with lysis buffer
(Mesoscale Discovery) and 25 .mu.g added to a multi-spot 96-well
Phospho-Akt carbon plate (Mesoscale Discovery) that had previously
been blocked with Blocking Solution-A (Mesoscale Discovery). The
plate was incubated at room temperature for one hour with shaking
before the lysate was aspirated and the wells washed four times
with Tris Wash buffer (Mesoscale Discovery). Phosphorylated Akt was
detected using 25 .mu.L, of SULFO-TAG anti-phospho-Akt (S473)
antibody (Mesoscale Discovery) diluted in antibody dilution buffer
by incubating with shaking at room temperature for one hour. The
wells were washed four times with Tris Wash buffer before adding
150 .mu.L of Read buffer T (with surfactant) (Mesoscale Discovery)
and the signal quantified using a Mesoscale Sector Imager.
Example 19: Phospho HER3 (Y1197) In Vivo PD Assays
[0434] Approximately 50 mm.sup.3 frozen tumor (e.g. BXPC-3) tissue
was thawed on ice and 100-300 .mu.L of T-PER buffer (Pierce)
containing phosphatase (Roche) and protease inhibitors (Roche) was
added to each sample. The tissue was broken down using a 1.5 mL
pestle (Fisher Scientific) and the resultant suspensions were
incubated on ice for 15 minutes before being frozen overnight at
-80.degree. C. Samples were thawed and spun for 15 minutes at 13000
g, 4.degree. C. prior to quantifying the supernatant protein
concentration by BCA assay (Thermo Scientific). Tissue supernatants
were diluted with lysis buffer and 150 .mu.g added to a multi-spot
96-well carbon plate (Mesoscale Discovery) that had previously been
coated overnight with 4 .mu.g/mL MAB3481 (R&D Systems) and
blocked with 3% milk. The plate was incubated at room temperature
for two hours with shaking before the lysate was aspirated and the
wells washed four times with Tris Wash buffer (Mesoscale
Discovery). Phosphorylated HER3 was bound using anti-HER3 pY1197
diluted 1/8000 with blocking buffer. Following incubation at room
temperature for one hour the wells were washed with Tris Wash
buffer and the anti-pY1197 antibody detected using S-Tag labelled
anti-rabbit antibody (Mesoscale Discovery) diluted 1/1000 in
blocking buffer by incubating with shaking at room temperature for
one hour. The wells were washed four times with Tris Wash buffer
before adding 150 .mu.l of 1/4 diluted Read buffer T (with
surfactant) (Mesoscale Discovery) and the signal quantified using a
Mesoscale Sector Imager.
Example 20: In Vitro Drug Combination Studies
[0435] To assess the ability of HER3-targeted antibodies to combine
with targeted therapies MOR09825 or MOR10703 were combined with
trastuzumab, lapatinib, BEZ235, BKM120, BYL719, RAD001, erlotinib
and cetuximab in cell viability assays. Approximately 1000-1500
SK-Br-3 (McCoy's), MDA-MB-453 (RPMI), FaDu (EMEM) or L3.3 (RPMI)
cells were seeded into 384-well plates in the appropriate culture
media supplemented with 2% FBS and allowed to adhere overnight at
37.degree. C. The appropriate drug combinations (typical final drug
concentrations for lapatinib, BKM120, and BYL719 ranged from 3
.mu.M to 13 nM; for RAD001 ranged from 27 nM to 0.0041 nM; for
erlotinib ranged from 1 .mu.M to 0.0025 nM; for MOR1073 ranged from
100 nm to 0.01 nm; for cetuximab ranged from 100 nM to 0.0015 nM;
and for trastuzumab ranged from 300 nM to 0.046 nM)) were
subsequently added to the wells such that each plate contained a
dose response curve of each drug in a two-dimensional matrix. The
plates were returned to the incubator for 3-6 days before assessing
cell viability using CellTiter-Glo (Promega). CellTiter-Glo
solution was added to each well and incubated at room temperature
with gentle shaking for 10 minutes. The amount of luminescence was
determined using a SpectraMax plate reader (Molecular Devices). The
extent of growth inhibition obtained with each combination was
calculated and combination activity highlighted using the Loewe
additivity model.
Example 21: In Vivo Drug Combination Studies in L3.3 Cells
[0436] Pancreatic L3.3 cells were cultured in DMEM medium
containing 10% heat-inactivated fetal bovine serum until the time
of implantation. Female Foxn1 nude mice (Harlan Laboratories) were
implanted subcutaneously with 3.times.10.sup.6 cells in FBS free
DMEM. The total injection volume containing cells in suspension was
100 .mu.L. 12 days following cell implantation, animals were
enrolled in the efficacy study with a mean tumor volume of
approximately 100 mm.sup.3 for all groups. In general, a total of 8
animals per group were enrolled in studies. Animals were excluded
from enrollment if they exhibited unusual tumor growth
characteristics prior to enrollment.
[0437] Animals were dosed intravenously with MOR10703 via lateral
tail vein injection on a 20 mg/kg, every other day schedule for the
duration of the study (14 days under treatment).
[0438] Erlotinib was dosed at 50 mg/kg (PO) on a daily schedule
either as a single-agent or in combination with MOR10703. Tumor
volume and T/C values were calculated as previously detailed.
Results and Discussion
[0439] Collectively, these results show that a class of antibodies
bind to amino acid residues within domain 2 and domain 4 of a
conformational epitope of HER3 and stabilizes HER3 in an inactive
or closed conformation. Binding of these antibodies inhibits both
ligand-dependent and ligand-independent signaling. These antibodies
are also able to bind concurrently with a HER3 ligand.
(i) Affinity Determination
[0440] Antibody affinity was determined by solution equilibrium
titration (SET) as described above. The results are summarized in
Table 9 and example titration curves for MOR10701 are contained in
FIG. 1. The data indicate that a number of antibodies were
identified that tightly bound human, cyno, rat and murine HER3.

(ii) SK-Br-3 Cell EC.sub.50 Determination
[0441] The ability of the identified antibodies to bind HER3
expressing cells was determined by calculating EC.sub.50 values for
their binding to the HER2 amplified cell line SK-Br-3 (see FIG. 2
and Table 10).

(iii) HER3 Domain Binding
[0442] A subset of anti-HER3 antibodies were characterized for
their ability to bind the various extracellular domains of human
HER3 in an ELISA assay. To achieve this, the extracellular domain
of HER3 was divided into its four constitutive domains and various
combinations of these domains were cloned, expressed and purified
as independent proteins as described above. Using this strategy the
following domains were successfully generated as soluble proteins:
domains 1 and 2 (D1-2), domain 2 (D2), domains 3 and 4 (D3-4) and
domain 4 (D4). A number of internally generated mouse anti-human
HER3 antibodies (8D7, 1F5 and 8P2) were also tested as positive
controls to demonstrate the integrity of each isolated domain.
[0443] As shown in FIG. 3 MOR09823 and MOR09825 were both observed
to successfully bind the HER3 extracellular domain, but little
binding to the isolated domains was observed in this assay with
these antibodies. There are several possible explanations for this
binding pattern:
[0444] a) MOR09823 and MOR09825 may bind a linear epitope that
spans a domain boundary thus part of the binding epitope would be
lost when the domains were expressed as isolated proteins.
[0445] b) MOR09823 and MOR09825 may bind a non-linear epitope that
bridges multiple domains. Consequently, separation of HER3 into its
component units may destroy the binding site.
[0446] c) The shape/conformation of HER3 may be a component of the
binding of MOR09823 and MOR09825 to HER3 such that only the
full-length extracellular domain of HER3 is capable of adopting
this shape/conformation whilst the isolated domains cannot fully
assume this conformation.
(vi) HER3 Epitope Mapping Using Hydrogen/Deuterium Exchange Mass
Spectrometry
[0447] The HER3 epitope was further explored by HDX-MS analysis of
HER3 ECD in the presence and absence of Fab versions of MOR09823,
MOR09824, MOR09825 and MOR09974. FIG. 4A shows that in the absence
of bound Fab, approximately 69% of the HER3 ECD sequence was
covered by at least one peptide. Gaps in coverage may be due to
glycosylation of residues within these regions or insufficient
reduction of disulphide bonds in cysteine rich regions, which is
particularly apparent in domain 2. Interestingly, although each Fab
yielded individual protection patterns, one region of strong
protection was consistently observed with MOR09823, MOR09824,
MOR09825 and MOR09974 (see FIG. 4B) indicating that these highly
related family of antibodies bind HER3 in an identical manner. The
strongest protection was observed for domain 2 residues 269-286
(TFQLEPNPHTKYQYGGVC) (SEQ ID NO: 496) indicating that residues in
this vicinity may be important for mAb binding. Mapping of the Fab
protected residues onto the published HER3 crystal structure (Cho
& Leahy, (2002) Science 297:1330-1333) highlights that residues
269-286 are within and proximal to a functionally important
.beta.-hairpin loop within domain 2 (see FIG. 4C).
(vii) HER3/MOR09823 Crystal Structure
[0448] The 3.2 .ANG. resolution x-ray crystal structure of MOR09823
Fab fragment bound to the HER3 extracellular domain was solved to
further define the HER3 epitope that is recognized by this family
of related antibodies (see FIG. 5A). In addition, the 3.4 .ANG.
structure of MOR09825 Fab fragment bound to human HER3 was
resolved. In both the MOR09823/HER3 and MOR09825/HER3 crystal
structures, HER3 is in the tethered (inactive) conformation (see
FIGS. 5A, B, C and D). This conformation is characterized by a
significant interaction interface between domains 2 and 4 mediated
by a .beta.-hairpin dimerization loop in domain 2. The observed
conformation of HER3 is similar to that previously described by Cho
et al. (Cho & Leahy, (2002), Science 297:1330-1333) who
published the crystal structure of the HER3 extra-cellular domain
in the absence of neuregulin. Since neuregulin can activate HER3,
the tethered conformation of HER3 is presumed to be inactive.
Similar tethered conformations have also been observed when the
related EGFR family members HER4 (Bouyain et al., (2005) Proc.
Natl. Acad. Sci. USA, 102:15024-15029) and HER1 (Ferguson et al.,
(2003) Molec. Cell 11:507-517) have been crystallized.
[0449] The spatial relationships between domains 1 to 4 of HER3 in
the inactive (tethered) state are significantly different from that
of the extended (active) state. This finding is based upon the
crystal structures of the related EGFR family members HER2 and
ligand-bound HER1 (Cho et al., (2003) Nature 421:756-760; Ogiso et
al., (2002) Cell 110:775-787; Garrett et al., (2002) Cell
110:763-773) both of which are in an extended (active) state. In
the extended state, the domain 2 .beta.-hairpin dimerization loop
is released from its inhibitory interaction with 4 and is thus free
to interact with its dimerization partner proteins. Thus, the
domain 2 .beta.-hairpin dimerization loop is functionally important
both in maintaining the tethered (inactive) state and in mediating
dimerization of EGF receptors in the extended state, leading to
activation of the intracellular kinase domain. The MOR09823/HER3
and MOR09825/HER3 crystal structures (see FIG. 5) therefore suggest
that both MOR09823 and MOR09825 function by stabilizing the
inactive conformation of HER3.
[0450] The crystal structure also revealed that the HER3 epitope
recognized by both MOR09823 and MOR09825 is a non-linear epitope
that includes residues from both domains 2 and 4 (see FIGS. 5C and
D, Tables 11, 12, 13 and 14). The HER3 epitope recognized by this
family of highly related antibodies can therefore be defined
as:
[0451] Domain 2: residues 265-277, 315
[0452] Domain 4 residues: 571, 582-584, 596-597, 600-602,
609-615
[0453] Binding of both domains 2 and 4 by MOR09823 or MOR09825
would consequently stabilize the tethered conformation of HER3 thus
antagonizing its ability to signal.
[0454] The MOR09823/MOR09825 binding mode observed in the crystal
structure is consistent with our other epitope mapping studies.
Specifically, the ELISA domain binding experiments demonstrate that
the affinity of MOR09823 and MOR09825 are significantly greater for
the intact HER3 extracellular protein than for any isolated domains
(e.g. D1, D1-D2, D3, or D3-D4 fragments) (see FIG. 3). There is
also agreement with the HER3 HDX-MS data (see FIG. 4B), which
identifies domain 2 .beta.-hairpin as part of the antibody
recognition epitope. Finally, both crystal structures indicate that
the ligand-binding surface of HER3, which has been mapped by
analogy to HER1 to domains 1 and 3 (Ogiso et al., (2002) Cell,
110:775-787; Garrett et al., (2002) Cell, 110:763-773) is not
occluded by either MOR09823 or MOR09825 binding (see FIG. 5B). This
is consistent with our findings that neither MOR09823 nor MOR09825
block neuregulin binding to MCF7 cells (see FIG. 9) and that
HER3/MOR09823 complexes can bind to immobilized neuregulin in
biacore studies (see FIG. 10).

[0455] Visual inspection of the MOR09823/MOR09825 crystal
structures highlighted that HER3 residues Lys267 and Leu268 formed
multiple interactions with various antibody CDR's suggesting that
they may be important for antibody binding. Consequently, Lys267
and/or Leu268 were mutated to alanine, expressed and the resultant
recombinant proteins purified in order to assess their impact upon
antibody binding. ELISA binding assays indicated that mutation of
either Lys267 or Leu268 abolished MOR10703 binding to HER3 (FIG.
5F) suggesting that both residues are an integral part of the HER3
epitope and thus supporting the proposed interactions between
MOR09823/MOR09825 and HER3.
(viii) Inhibition of Cell Signaling
[0456] To ascertain the effect of anti-HER3 antibodies upon ligand
dependent HER3 activity MCF7 cells were incubated with IgG prior to
stimulation with neuregulin. Example inhibition curves are
illustrated in FIG. 6A and summarized in Table 15. The effect of
anti-HER3 antibodies upon HER2-mediated HER3 activation was also
studied using the HER2 amplified cell line SK-Br-3 (FIG. 6B and
Table 15).

[0457] To determine whether inhibition of HER3 activity impacted
downstream cell signaling Akt, phosphorylation was also measured in
HER2 amplified cells following treatment with anti-HER3 antibodies
(see FIG. 7 and Table 16).

[0458] In summary MOR09823, MOR09824, MOR09825, MOR09974, MOR10701,
MOR10702 MOR10703, MOR12609 and MOR12610 are each capable of
inhibiting cellular HER3 activity in both a ligand-dependent and
ligand-independent manner.
(ix) Inhibition of Proliferation
[0459] Since MOR09823, MOR09824, MOR09825, MOR09974, MOR10701,
MOR10702 and MOR10703 all inhibited HER3 activity and downstream
signaling they were tested for their ability to block ligand
dependent and independent in vitro cell growth (Example data is
shown in FIG. 8 and summarized in Table 17). The anti-HER3
antibodies tested were all effective inhibitors of cell
proliferation.

(x) Ligand Blocking Assessment
[0460] The ability of the described anti-HER3 antibodies to block
ligand binding was assessed by examining the binding of neuregulin
to MCF7 cells previously treated with either MOR09823 or MOR09825.
The presence of either MOR09823 or MOR09825 had no significant
effect upon the ability of neuregulin to bind MCF7 cells whilst the
positive control used in the experiment (Mab3481) was capable of
profoundly interfering with neuregulin binding (see FIG. 9). These
results are consistent with the crystal structure since MOR09823
interacts with domains 2 and 4 whilst the major contact points for
HER3's interaction with neuregulin are hypothesized to be primarily
clustered within domains 1 and 3. Given that neuregulin is capable
of binding the inactive conformation of HER3 (Kani et al., (2005)
Biochemistry 44: 15842-15857) it is probable that MOR09823 and
MOR09825 function by preventing the HER3 domain rearrangements
necessary for signaling or by interfering with receptor
dimerization.
(xi) Ligand Blocking Assessment (Biochemical)
[0461] To explore whether MOR09823 and neuregulin can bind HER3
concurrently a biochemical assay was established using Biacore.TM.
technology. Interaction analyses were performed by capturing
biotinylated neuregulin on the surface of a Biacore.TM. sensor chip
CAP (GE Healthcare) utilizing a Biotin CAPture kit (GE Healthcare).
HER3 complexes were generated by incubating human HER3-Fc with
increasing concentrations of either MOR09823, 105.5 (Thermo
Scientific) or human IgG. Preformed HER3/antibody complexes were
injected over reference and active surfaces and the interaction of
HER3 with neuregulin observed.
[0462] Control IgG had no effect upon HER3/neuregulin complex
formation whilst 105.5 was observed to significantly inhibit the
ability of HER3 to bind neuregulin confirming its description as a
ligand blocking antibody (FIG. 10). In contrast HER3/MOR09823
complexes were capable of binding neuregulin demonstrating that
MOR09823 does not prevent ligand binding. Interestingly, a
dose-dependent increase in RU values was uniquely observed when
MOR09823/HER3 complexes were injected. This data indicates that a
trimeric complex containing neuregulin, HER3 and MOR09823 is
generated on the chip surface. The ability of this trimeric complex
to form is predicted by the HER3/MOR09823 crystal structure since
MOR09823 binding does not occlude the ligand binding site of HER3
suggesting that binding of neuregulin and MOR09823 are not mutually
exclusive.
[0463] In another embodiment, the antibody or fragment thereof
binds to both domain 2 and domain 4 of HER3 and without blocking
the concurrent binding of a HER3 ligand such as neuregulin. While
not required to provide a theory, it is feasible that the antibody
or fragment thereof binding to both domain 2 and domain 4 of HER3,
holds HER3 in an inactive conformation without blocking the ligand
binding site on HER3. Thus a HER3 ligand (e.g., neuregulin) is able
to bind to HER3 at the same time as the antibody.
[0464] The antibodies of the invention or fragments thereof inhibit
both ligand dependent and independent activation of HER3 without
preventing ligand binding. This is considered advantageous for the
following reasons:
[0465] (i) The therapeutic antibody would have clinical utility in
a broad spectrum of tumors than an antibody which targeted a single
mechanism of HER3 activation (i.e. ligand dependent or ligand
independent) since distinct tumor types are driven by each
mechanism.
[0466] (ii) The therapeutic antibody would be efficacious in tumor
types where both mechanisms of HER3 activation are simultaneously
involved. An antibody targeting a single mechanism of HER3
activation (i.e. ligand dependent or ligand independent) would
display little or no efficacy in these tumor types
[0467] (iii) The efficacy of an antibody which inhibits ligand
dependent activation of HER3 without preventing ligand binding
would be less likely to be adversely affected by increasing
concentrations of ligand. This would translate to either increased
efficacy in a tumor type driven by very high concentrations of HER3
ligand or a reduced drug resistance liability where resistance is
mediated by up-regulation of HER3 ligands.
[0468] (iv) An antibody which inhibits HER3 activation by
stabilizing the inactive form would be less prone to drug
resistance driven by alternative mechanisms of HER3 activation.
[0469] Consequently, the antibodies of the invention may be used to
treat conditions where existing therapeutic antibodies are
clinically ineffective.
(xii) In Vivo Inhibition of HER3 Activity and Effect Upon Tumor
Growth
[0470] To determine the in vivo activity of the described anti-HER3
antibodies, MOR09823 was tested in both BxPC-3 and BT-474 tumor
models. MOR09823 was demonstrated to inhibit HER3 activity as
evidenced by a significant reduction in tumor pHER3 levels (FIG.
11). Signaling downstream of HER3 was similarly inhibited as
demonstrated by reduced pAkt levels in both BxPC-3 and BT-474 (FIG.
11). In a HER2 driven BT-474 efficacy study, repeated MOR10701
treatment yielded a 74% inhibition of tumor growth (see FIG. 12A)
whilst MOR10703 yielded 83% inhibition. In the BxPC3 tumor growth
model, both MOR10701 and MOR10703 very effectively inhibited ligand
driven tumor growth (see FIG. 13).
(xiii) In Vitro Drug Combinations and Impact Upon Cell Growth.
[0471] Since tumor cell growth is frequently driven by multiple
signaling pathways we assessed whether combinations of MOR09823 or
MOR10703 with various targeted agents would be of benefit in
blocking cell proliferation. The targeted agents chosen primarily
inhibited HER2 (trastuzumab, lapatinib) EGFR (cetuximab,
erlotinib), PI3K/mTOR (BEZ235), PI3K (BKM120), PIK3CA (BYL719) and
mTOR (RAD001) since these targets are commonly activated in human
tumors. Isobologram analysis (see FIG. 14) indicated that MOR09823
and MOR10703 displayed synergistic drug combinations with
trastuzumab, lapatinib, erlotinib, cetuximab, BEZ235, BKM120,
BYL719 and RAD001. This data suggests that inhibition of HER3
signaling is of particular benefit to inhibitors that target
receptor tyrosine kinases or the PI3K signaling pathway.
(xiv) In Vivo MOR10703 Drug Combinations
[0472] Since HER3 inhibition combined with receptor tyrosine kinase
targeted agents in vitro we assessed the impact of either MOR10701
or MOR10703 in combination with trastuzumab and erlotinib in vivo.
In BT-474 xenografts (see FIG. 15A), combination of either MOR10701
or MOR10703 (20 mg/kg) with a sub-optimal dose of trastuzumab (1
mg/kg) was sufficient to induce tumor regressions (% T/C=-50 and
-37 respectively). In L3.3 pancreatic xenografts, combination of
MOR10703 (20 mg/kg) with daily erlotinib (50 mg/kg) resulted in
tumor stasis (% T/C=3, see FIG. 15B). In both models, the
combination of two drugs was significantly more efficacious than
either drug alone thus supporting our earlier in vitro finding of
the benefit of combining HER3-targeted antibodies with
ErbB-targeted agents.
[0473] In summary, the unique ability of this family of antibodies
to stabilize the inactive conformation of HER3 results in
significant in vivo efficacy in models where HER3 is activated in
either a ligand dependent or independent manner. Furthermore, HER3
inhibition by this family of antibodies appears beneficial in
combination with a wide variety of targeted therapies.
Example 22: HER3 Antibodies for Benign Prostatic Hyperplasia (BPH),
Gynecomastia, and Endometriosis
Experimental Procedure
[0474] Sexually mature IGS Wistar Hannover rats of approximately 9
weeks of age were dosed via intravenous injection on a twice weekly
schedule with 30, 75 and 200 mg/kg MOR10703. Following completion
of the 13 week dosing period, 10 rats from each dose group were
sacrificed and major organs collected for further analysis. In
addition, 6 rats from the 200 mg/kg dose group were allowed to
recover from MOR10703 for 10 weeks prior to sacrifice in order to
determine the reversibility of any observed changes. Post animal
sacrifice, organ weights were recorded prior to fixation in 10%
neutral-buffered formalin. Tissue sections were prepared and
assessed by microscopic examination.
Results
[0475] In male rats, decreased prostate weight was observed at all
doses, which correlated with reduced secretion in the prostate and
seminal vesicles (Table 18). These effects were reversible after 10
weeks of recovery. Differences in absolute mean vs. control were as
follows: 30 mg/kg: -31%, 75 mg/kg: -40%, and 200 mg/kg: -35%.
Mammary gland atrophy, mostly moderate or marked, was present in
all dosed males and was not reversible after 10 weeks recovery.
This change was characterized by the absence of the normally
abundant acinar and lobular development seen in the male mammary
gland. By contrast to the controls, sparse ductular elements were
present in the mammary glands of all treated males.

[0476] In females, decreased uterus weight was observed at all
doses, which was reversible after 10 weeks of recovery (Table 19).
Absolute mean vs. control differences were 30 mg/kg: -24%, 75
mg/kg: -27%, and 200 mg/kg: -19%. Endometrial atrophy, observed as
a profound decrease in glandular epithelium in the uterus at all
doses >30 mg/kg/day correlated with the decrease in uterus
weights observed at the end of treatment. This was slightly
reversible after 10 weeks of recovery in that an increased amount
of glandular epithelium was present although not as much as in
control animals. Other reproductive organs: ovaries, oviducts,
cervix and vagina appeared to be within normal limits, considering
the different stages of the cycle that can be observed.

Discussion
[0477] Benign prostatic hyperplasia (BPH) is a common disease in
aging males that is characterized by a non-neoplastic enlargement
of the prostate leading to pressure on the urethra and resulting in
urination and bladder problems {Mahapokail W, van Sluijs F J &
Schalken J A. 2000 Prostate Cancer and Prostatic Diseases 3,
28-33}. Anatomic or microscopic evidence of BPH is present at
autopsy in approximately 55% of men aged 60-70 years. Transurethal
resection of the prostate has been the treatment of choice for many
years. Consequently, BPH is one of the most common reasons for
surgical intervention among elderly men. Less invasive methods of
treatment include:
[0478] (i) Alpha 1-blockers (doxazosin, prazosin, tamsulosin,
terazosin, and alfuzosin) are a class of medications also used to
treat high blood pressure. These medications relax the muscles of
the bladder neck and prostate thus allowing easier urination.
[0479] (ii) Finasteride and dutasteride lower androgen levels thus
reducing the size of the prostate gland, increasing urine flow
rate, and decreasing symptoms of BPH. It may take 3 to 6 months
before improvement in symptoms is observed. Potential side effects
related to the use of finasteride and dutasteride include decreased
sex drive and impotence
[0480] The results in the Experiments section demonstrate for the
first time that BPH is a neuregulin-dependent indication. The
finding that MOR10703 significantly reduced prostate size in
sexually mature rats without affecting hormone levels suggests that
MOR10703 could be useful for the treatment of BPH.
[0481] To further test MOR10703 and other HER3 antibodies as
therapeutics for BPH, primary human BPH surgical specimens can be
transplanted into athymic mice or rats and effect of the Her3
antibodies studied using models (Otto U et al. Urol Int 1992; 48:
167-170). Alternatively, aspects of BPH can be induced in castrated
dogs via the long-term administration of 5.alpha.-Androstane-3a,
170-diol plus estradiol and the HER3 antibodies tested in these
canine models (Walsh P C, Wilson J D. J Clin Invest 1976; 57:
1093-1097).
[0482] The physical manifestation of gynecomastia is breast
enlargement in males, it normally occurs in both breasts but can
sometimes be in one only, known as asymmetrical or unilateral
gynecosmastia. Gynecomastia is commonly caused by:
[0483] (i) Elevated estrogen levels resulting in the ratio of
testosterone to oestrogen becoming unbalanced.
[0484] (ii) Androgen antagonists or anti-androgens used in the
treatment of prostate cancer or BPH. These drugs suppress
testosterone but by suppressing testosterone, oestrogen begins to
rise.
[0485] Although a number of experimental drugs are currently being
evaluated there are currently no approved treatments for
gynecomastia. Consequently gynecomastia is treated via surgical
removal of the breast tissue. The observation that MOR10703 induced
irreversible atrophy of the male mammary gland indicates that it
may be of benefit in the treatment of gynecomastia.
[0486] To further test MOR10703 and other HER3 antibodies for
treating human gynecomastia, transgenic mouse models of
gynecomastia can be used. These models have been developed by
expressing human aromatase in the mouse mammary gland and
recapitulate many aspects of human gynecomastia (Li et al.,
Endocrinology 2002; 143:4074-4083; Tekmal et al., Cancer Res 1996;
56:3180-318).
[0487] MOR10703 and other HER3 antibodies can also be examined for
treating endometriosis, a gynecological condition in which cells
from the lining of the uterus (endometrium) appear and flourish
outside the uterine cavity. The main, but not universal, symptom of
endometriosis is pelvic pain in various manifestations. Although
the underlying causes of endometriosis are not well characterized
is thought to be dependent on the presence of estrogen. Since
MOR10703 induced endometrial atrophy in female mice resulting in a
decrease in uterus weight, it may be used to treat endometriosis.
To further study the effects of MOR10703 and other HER3 antibodies
on endometriosis, human endometrium in the proliferative phase can
be implanted into the peritoneal cavity of normal cycling and
ovariectomized athymic mice or cycling non-obese diabetic
(NOD)-severe combined immuno-deficiency (SCID) mice, and these SCID
mice used as models (Grummer et al., 2001. Human Reproduction; 16;
1736-1743).
Example 23: In Vitro Studies to Assess HER3 Antibodies for
Esophageal Cancer
In Vitro Esophageal Drug Combination Studies
[0488] To assess the ability of HER3-targeted antibodies to combine
with targeted therapies MOR10703 was combined with cetuximab or
BYL719 in cell viability assays. Approximately 1000-1200 KYSE140
and KYSE180 cells were seeded into 384-well plates in the
appropriate culture media supplemented with 2% FBS and allowed to
adhere overnight at 37.degree. C. The appropriate drug combinations
(typical final drug concentrations for BYL719 ranged from 2.8 .mu.M
to 3.8 nM; for cetuximab ranged from 93 nM to 0.13 nM; for MOR10703
100 nM to 4.1 nM) were subsequently added to the wells such that
each plate contained a dose response curve of each drug in a
two-dimensional matrix. Treated cells were subsequently incubated
for 96-120 hours. At the end of the drug treatment, CellTiter-Glo
regent were added to each well to lyse the cells, and luminescence
signals were recorded using an Envision plate reader. The extent of
growth inhibition obtained with each combination was calculated and
combination activity highlighted using the Loewe additivity
model.
Esophageal In Vitro Drug Combinations and Impact Upon Cell
Growth
[0489] Since tumor cell growth is frequently driven by multiple
signaling pathways, combinations of MOR10703 with cetuximab or
BYL719 were assessed to determine whether they would be of benefit
in blocking proliferation of esophageal cancer cell lines. The
targeted agents chosen primarily inhibited EGFR (cetuximab) and
PIK3CA (BYL719) since these targets are commonly activated in human
tumors. Isobologram analysis (see FIG. 16) indicated that MOR10703
displayed synergistic drug combinations with cetuximab and BYL719.
This data shows that inhibition of HER3 signaling is of particular
benefit to inhibitors that target receptor tyrosine kinases or the
PI3K signaling pathway.
Example 24: In Vivo Studies to Assess HER3 Antibodies for
Esophageal Cancer
[0490] To assess the in vivo ability of HER3-targeted antibodies to
combine with targeted therapies MOR10703 was combined with
cetuximab or BYL719 and tested in two in vivo xenograft models.
(i) In Vivo KYSE140 Xenografts
[0491] KYSE140 cells were cultured in RPMI 1640 medium containing
10% heat-inactivated fetal bovine serum without antibiotics until
the time of implantation. KYSE140 cells were harvested in
exponential growth. Ten million cells were mixed with PBS/Matrigel
(50:50) were subcutaneously implanted into the upper right flank of
SCID-Beige mice. On Day 28, tumors were measured and animals with a
tumor volume of approximately 200 mm.sup.3 were enrolled in the
efficacy study. In general, a total of 10 animals per group were
enrolled in efficacy studies. For single-agent and combination
studies, animals were dosed intravenously via lateral tail vein
injection with MOR10703 or cetuximab. BYL719 was formulated in 0.5%
methylcellulose and dosed via oral gavage.
(ii) In Vivo KYSE180 Xenografts
[0492] KYSE180 cells were cultured in RPMI 1640 medium containing
10% heat-inactivated fetal bovine serum without antibiotics until
the time of implantation. KYSE180 cells were harvested in
exponential growth. Five million cells were subcutaneously
implanted into the upper right flank of nude mice. On Day 18,
tumors were measured and animals with a tumor volume of
approximately 200 mm.sup.3 were enrolled in the efficacy study. In
general, a total of 10 animals per group were enrolled in efficacy
studies. For single-agent and combination studies, animals were
dosed intravenously via lateral tail vein injection with MOR10703
or cetuximab. BYL719 was formulated in 0.5% methylcellulose and
dosed via oral gavage.
(iii) In Vivo Primary Esophageal Xenografts
[0493] Human esophageal primary tumors were passaged in mice. When
tumor size reached approximately 150 mm.sup.3 in size, animals were
enrolled in the efficacy study. For single-agent and combination
studies, animals were dosed intravenously via lateral tail vein
injection with MOR10703 or cetuximab. BYL719 was formulated in 0.5%
methylcellulose and dosed via oral gavage.
In Vivo Inhibition of HER3 and Effect Upon Esophageal Tumor
Growth
[0494] To determine the in vivo activity of the described anti-HER3
antibodies, MOR10703 was tested in both KYSE140 and KYSE180
esophageal tumor models, as well as two primary esophageal tumor
models, CHES007 and CHES015. In both KYSE140 and KYSE180 in vivo
models, treatment with single-agent MOR10703 was demonstrated to
effectively inhibit tumor growth (FIG. 17). In KYSE180, the
combination of MOR10703 and BYL719 was sufficient to induce
significant tumor regressions. These findings were extended to the
primary esophageal tumor models, where a combination of MOR10703
with either cetuximab or BYL719 also induced potent tumor
regressions (FIG. 18). Together, these data further support our
earlier in vitro finding of the benefit of combining HER3-targeted
antibodies with wither EGFR or PI3K-targeted agents.
Example 25: In Vivo Studies to Assess HER3 Combinations with BYL719
in Gastric Cancer
[0495] To assess the in vivo ability of HER3-targeted antibodies to
combine with targeted therapies in gastric cancer, MOR10703 was
combined with BYL719 and tested in an in vivo xenograft model.
(i). In Vivo NCI-N87 Xenograft
[0496] NCI-N87 cells were grown in DMEM culture medium containing
4.5 g/l glucose supplemented with 10% heat-inactivated FCS, 2 mM
L-glutamine, 1 mM sodium pyruvate until the point of implantation.
NCI-N87 tumors were established by injecting 8.times.106 to
1.times.107 cells (in HBSS containing 50% v/v Matrigel)
subcutaneously. On Day 10, tumors were measured and animals with a
tumor volume of approximately 250 mm.sup.3 were enrolled in the
efficacy study. For single-agent and combination arms, animals were
dosed intravenously via lateral tail vein injection with MOR10703.
BYL719 was formulated in 0.5% methylcellulose and dosed via oral
gavage.
Effect of Combination Treatment on N87 Gastric Tumor Growth
[0497] As seen was seen for esophageal tumors, the combination of
MOR10703 and BYL719 was sufficient to induce significant, prolonged
tumor regressions in the N87 gastric tumor model thus further
supporting the benefit of combining HER3-targeted antibodies with
PI3K-targeted agents (see FIG. 19).
Example 26: In Vivo Studies to Assess HER3 Combinations with
Cetuximab in Squamous Cell Cancer of the Head and Neck (SCCHN)
[0498] To assess the in vivo ability of HER3-targeted antibodies to
combine with targeted therapies in SCCHN, MOR10703 was combined
with cetuximab and tested in an in vivo xenograft model.
(i). In Vivo A253 Xenograft
[0499] A253 cells were cultured in DMEM containing 10%
heat-inactivated fetal bovine serum without antibiotics until the
time of implantation. A253 cells were harvested in exponential
growth. Five million cells in 200 .mu.l PBS were subcutaneously
implanted into the upper right flank of nude mice. On Day 25,
tumors were measured and animals with a tumor volume of
approximately 200 mm3 were enrolled in the efficacy study. In
general, a total of 9 animals per group were enrolled in efficacy
studies. For single-agent and combination studies, animals were
dosed intravenously via lateral tail vein injection with MOR10703
or cetuximab.
Effect of Combination Treatment on A253 SCCHN Tumor Growth
[0500] In the A253 SCCHN model, treatment with either MOR10703 or
cetuximab as a single agent resulted in tumor stasis. Combination
of MOR10703 with cetuximab was significantly more active and
resulted in tumor regression (see FIG. 20).
[0501] Collectively, these results show MOR10703 as a single agent
can inhibit tumor growth. The results also show there is a
synergistic effect on tumor regression when MOR10703 is combined
with inhibitors that target other receptor tyrosine kinases or the
PI3K signaling pathway.
