FIELD OF THE INVENTION
[0004] The present invention relates to the detection and treatment
of rheumatoid arthritis (RA). The invention involves use of a
binding member that binds the ED-A isoform of fibronectin,
especially a binding member that binds domain ED-A of
fibronectin.
[0005] Rheumatoid arthritis (RA) is a chronic inflammatory and
destructive joint disease that affects 0.5-1% of the population in
the industrialized world and commonly leads to significant
disability and a consequent reduction in quality of life.
[0006] Angiogenesis in the synovial membrane of patients with RA is
considered to be an important early step in pathogenesis and in the
perpetuation of disease (Taylor, 2002). As in neoplastic disease,
angiogenesis feeds the expanding synovium (Walsh et al., 1998).
Blood vessel growth probably contributes to the proliferation of
the inflammatory synovial pannus as well as to the ingress of
inflammatory leukocytes into the synovial tissue. Synovium of
patients with RA contained increased amounts of fibroblast growth
factor-2 (FGF-2) and of vascular endothelial growth factor (VEGF)
(Koch, 2003). Serum VEGF concentrations correlate with disease
activity and fall, when synovitis is successfully suppressed by
therapy (Taylor, 2002).
[0007] Fibronectin (FN) is a glycoprotein and is widely expressed
in a variety of normal tissues and body fluids. It is a component
of the extracellular matrix (ECM), and plays a role in many
biological processes, including cellular adhesion, cellular
migration, haemostasis, thrombosis, wound healing, tissue
differentiation and oncogenic transformation.
[0008] Different FN isoforms are generated by alternative splicing
of three regions (ED-A, ED-B, IIICS) of the primary transcript FN
pre-mRNA, a process that is modulated by cytokines and
extracellular pH (Balza 1988; Carnemolla 1989; Borsi 1990; Borsi
1995). Fibronectin contains two type-III globular extra-domains
which may undergo alternative splicing: ED-A and ED-B
(ffrench-Constant 1995, Hynes 1990, Kaspar et al. 2006). The ED-As
of mouse fibronectin and human fibronectin are 96.7% identical
(only 3 amino acids differ between the two 90 amino acid sequences,
see FIG. 2).
[0009] Expression of the ED-A of fibronectin has been reported in
tumour cells and in solid tumours at the mRNA level in breast
cancer (Jacobs et al. 2002, Matsumoto et al. 1999) and liver cancer
(Oyama et al. 1989, Tavian et al. 1994) and at the level of
isolated protein in fibrosarcoma, rhabdomyosarcoma and melanoma
(Borsi et al. 1987).
[0010] At the immunohistochemical level, the presence of ED-A has
been detected in the extracellular matrix (ECM) of odontogenic
tumours (Heikinheimo et al. 1991) and hepatocellular carcinoma
(Koukoulis et al. 1995). In contrast, ED-A has been detected in the
stroma of malignant breast neoplasms (Koukoulis et al. 1993), and
in the blood vessels and basement membranes of well-differentiated
renal cell carcinoma (Lohi et al. 1995). However, in
less-differentiated renal cell carcinoma (Lohi et al. 1995) and
papillary carcinoma of the thyroid (Scarpino et al. 1999) ED-A has
been detected in the blood vessels, basement membranes and tumour
stroma. The presence of ED-A in the vasculature of gliomas has also
been reported (Borsi et al. 1998). Thus, the pattern of ED-A
expression reported for different types of tumours is highly
variable.
[0011] Antibody-based targeted delivery of bioactive agents to
sites of angiogenesis is an attractive therapeutic strategy for
cancer treatment, but is largely unexplored for chronic
inflammatory diseases. We have previously demonstrated that the
ED-B domain of fibronectin, a marker of angiogenesis, is expressed
in psoriatic lesions in patients and in a mouse model of psoriasis
as well as in arthritic paws in the collagen-induced mouse model of
rheumatoid arthritis. Using both radioactive and fluorescent
techniques, the human monoclonal antibody L19, specific to EDB, was
found to selectively localize at sites of inflammation in vivo,
following intravenous administration. These results suggest a
therapeutic potential for the L19-based selective delivery of
bioactive compounds to sites of inflammation (Trachsel, 2007;
PCT/EP2007/004044).
[0012] It has been shown before by in-situ-hybridisation that other
than ED-B also the ED-A domain of fibronectin can be present in
human arthritic specimens (Berndt et al., 1998; Kriegsmann et al.,
2004).
BACKGROUND OF THE INVENTION
[0013] We show herein that anti-EDA antibody, such as the F8
antibody disclosed herein, is able to give a stronger staining
pattern on human arthritic specimens compared with the
anti-EDB-antibody L19 and the anti-tenascin-C antibodies F16 and
G11.
[0014] Furthermore, using both radioactive and fluorescent
techniques, the human monoclonal antibody F8, specific to ED-A, was
found to selectively localize at sites of inflammation in vivo,
following intravenous administration.
[0015] Accordingly, ED-A of fibronectin is indicated as a vascular
marker of rheumatoid arthritis.
[0016] Binding molecules such as antibody molecules that bind the
A-FN and/or the ED-A of fibronectin represent novel agents which
may be used for the preparation of a medicament for the treatment
of rheumatoid arthritis (RA).
[0017] This invention provides the use of a binding member, e.g. an
antibody molecule, that binds the Extra Domain-A (ED-A) isoform of
fibronectin (A-FN), for the preparation of a medicament for the
treatment of rheumatoid arthritis. The invention also provides the
use of a binding member, e.g. an antibody molecule, that binds the
ED-A of fibronectin for the preparation of a medicament for the
treatment of rheumatoid arthritis.
[0018] The invention further provides the use of a binding member,
e.g. an antibody molecule, that binds the ED-A isoform of
fibronectin for delivery, to sites of rheumatoid arthritis, of a
molecule conjugated to the binding member. The invention also
provides the use of a binding member, e.g. an antibody molecule,
that binds the ED-A of fibronectin for delivery, to sites of
rheumatoid arthritis, of a molecule conjugated to the binding
member. The binding member may be used for the manufacture of a
medicament for delivery of such a molecule.
[0019] The invention provides the use of a binding member, e.g. an
antibody molecule, that binds the ED-A isoform of fibronectin for
the manufacture of a diagnostic product for use in diagnosing
rheumatoid arthritis. The invention also provides the use of a
binding member, e.g. an antibody molecule, that binds the ED-A of
fibronectin for the manufacture of a diagnostic product for use in
diagnosing rheumatoid arthritis.
[0020] The invention further provides a method of detecting or

[0022] (b) determining the presence or absence of the binding
member in sites of rheumatoid arthritis of the human or animal
body; wherein localisation of the binding member to sites of
rheumatoid arthritis indicates the presence of rheumatoid
arthritis.
[0023] The present invention provides a method of treating
rheumatoid arthritis in an individual comprising administering to
the individual a therapeutically effective amount of a medicament
comprising a binding member, e.g. an antibody molecule, which binds

isoform of fibronectin, for use in a method of treating rheumatoid
arthritis in an individual comprising administering to the
individual a therapeutically effective amount of a medicament

a method of treating rheumatoid arthritis in an individual
comprising administering to the individual a therapeutically

[0025] The invention provides a method of delivering a molecule to
the neovasculature of sites of rheumatoid arthritis in a human or
animal comprising administering to the human or animal a binding
member, e.g. an antibody molecule, which binds the ED-A isoform of
fibronectin, wherein the binding member is conjugated to the
molecule. The invention also provides a method of delivering a
molecule to the neovasculature of sites of rheumatoid arthritis in
a human or animal comprising administering to the human or animal a

E5, C8, F8, F1, B7, E8 or G9 with ten or fewer, e.g. one, two,
three, four, or five, amino acid substitutions within the disclosed
set of H and/or L CDRs. Preferably, a binding member for use in the
invention comprises a set of H and/or L CDRs of antibody B2, C5,
D5, C8, F8, B7 or G9 with ten or fewer, e.g. one, two, three, four,

substitutions within the disclosed set of H and/or L CDRs.
[0028] Substitutions may potentially be made at any residue within
the set of CDRs, and may be within CDR1, CDR2 and/or CDR3.
[0029] For example, a binding member for use in the invention may
comprise one or more CDRs as described herein, e.g. a CDR3, and
optionally also a CDR1 and CDR2 to form a set of CDRs.
[0030] A binding member for use in the invention may also comprise
an antibody molecule, e.g. a human antibody molecule. The binding
member normally comprises an antibody VH and/or VL domain. VH
domains of binding members are also provided for use in the
invention. Within each of the VH and VL domains are complementarity
determining regions, ("CDRs"), and framework regions, ("FRs"). A VH
domain comprises a set of HCDRs, and a VL domain comprises a set of
LCDRs. An antibody molecule may comprise an antibody VH domain
comprising a VH CDR1, CDR2 and CDR3 and a framework. It may
alternatively or also comprise an antibody VL domain comprising a
VL CDR1, CDR2 and CDR3 and a framework. The VH and VL domains and
CDRs of antibodies H1, B2, C5, D5, E5, C8, F8, F1, B7, E8 and G9
are described herein. All VH and VL sequences, CDR sequences, sets
of CDRs and sets of HCDRs and sets of LCDRs disclosed herein
represent embodiments of a binding member for use in the invention.

Preferably, the HCDR1 is SEQ ID NO: 23, 33, 43, 53, 73, 83 or 103.
Most preferably, the HCDR1 is SEQ ID NO: 83.
[0032] Typically, a VH domain is paired with a VL domain to provide
an antibody antigen-binding site, although as discussed further
below a VH or VL domain alone may be used to bind antigen. Thus, a
binding member for use in the invention may further comprise an
antibody VL domain comprising complementarity determining regions
LCDR1, LCDR2 and LCDR3 and a framework, wherein LCDR1 is SEQ ID NO:
6, 26, 36, 46, 56, 66, 76, 86, 96, 106 or 116 and wherein

[0040] One or more CDRs or a set of CDRs of an antibody may be
grafted into a framework (e.g. human framework) to provide an
antibody molecule for use in the invention. Framework regions may
comprise human germline gene segment sequences. Thus, the framework
may be germlined, whereby one or more residues within the framework
are changed to match the residues at the equivalent position in the
most similar human germline framework. A binding member for use in
the invention may be an isolated antibody molecule having a VH
domain comprising a set of HCDRs in a human germline framework,
e.g. DP47. Normally the binding member also has a VL domain
comprising a set of LCDRs, e.g. in a human germline framework. The
human germline framework of the VL domain may be DPK22.
[0041] A VH domain for use in the invention may have amino acid
sequence SEQ ID NO: 1, 21, 31, 41, 51, 61, 71, 81, 91, 101 or 111.
Preferably, a VH domain for use in the invention has amino acid
sequence SEQ ID NO: 21, 31, 41, 51, 71, 81 or 101. Most preferably,
a VH domain for use in the invention has amino acid sequence SEQ ID
NO: 81. A VL domain for use in the invention may have the amino
acid SEQ ID NO: 2, 22, 32, 42, 52, 62, 72, 82, 92, 102 or 112.
Preferably, a VL domain for use in the invention has amino acid SEQ
ID NO: 22, 32, 42, 52, 72, 82 or 102. Most preferably, a VL domain
for use in the invention has amino acid SEQ ID NO: 82.
[0042] A binding member for use in the invention may be or comprise
a single chain Fv (scFv), comprising a VH domain and a VL domain
joined via a peptide linker. The skilled person may select an
appropriate length and sequence of linker, e.g. at least 5 or 10
amino acids in length, up to about 15, 20 or 25 amino acids in
length. The linker may have the amino acid sequence GSSGG (SEQ ID
NO: 28). The scFv may consist of or comprise amino acid sequence
SEQ ID NO: 9.
[0043] A single chain Fv (scFv) may be comprised within a
mini-immunoglobulin or small immunoprotein (SIP), e.g. as described
in (Li et al., 1997). A sip may comprise an scFv molecule fused to
the CH4 domain of the human IgE secretory isoform IgE-S2
(.epsilon..sub.s2-CH4; Batista et al., 1996) forming an
homo-dimeric mini-immunoglobulin antibody molecule.
[0044] Alternatively, a binding member for use in the invention may
comprise an antigen-binding site within a non-antibody molecule,
normally provided by one or more CDRs e.g. a set of CDRs in a
non-antibody protein scaffold. Binding members, including
non-antibody and antibody molecules, are described in more detail
elsewhere herein.
[0045] A binding member for use in the invention may be conjugated
to a molecule that has biocidal, cytotoxic immunosuppressive or
anti-inflammatory activity. Interleukin-10 is an advantageous
molecule for conjugation with a binding member in accordance with
the present invention, and useful in treatment of rheumatoid
arthritis. Furthermore, a binding member for use in the invention
may be conjugated to a radioisotope, a detectable lable or a
photosensitizer.
[0046] These and other aspects of the invention are described in
further detail below.

DETAILED DESCRIPTION OF THE INVENTION
Terminology
[0063] Fibronectin
[0064] Fibronectin is an antigen subject to alternative splicing,
and a number of alternative isoforms of fibronectin are known, as
described elsewhere herein. Extra Domain-A (EDA or ED-A) is also
known as ED, extra type III repeat A (EIIIA) or EDI. The sequence
of human ED-A has been published by Kornblihtt et al. (1984),
Nucleic Acids Res. 12, 5853-5868 and Paolella et al. (1988),
Nucleic Acids Res. 16, 3545-3557. The sequence of human ED-A is
also available on the SwissProt database as amino acids 1631-1720
(Fibronectin type-III 12; extra domain 2) of the amino acid
sequence deposited under accession number P02751. The sequence of
mouse ED-A is available on the SwissProt database as amino acids
1721-1810 (Fibronectin type-III 13; extra domain 2) of the amino
acid sequence deposited under accession number P11276.
[0065] The ED-A isoform of fibronectin (A-FN) contains the Extra
Domain-A (ED-A). The sequence of the human A-FN can be deduced from
the corresponding human fibronectin precursor sequence which is
available on the SwissProt database under accession number P02751.
The sequence of the mouse A-FN can be deduced from the
corresponding mouse fibronectin precursor sequence which is
available on the SwissProt database under accession number P11276.
The A-FN may be the human ED-A isoform of fibronectin. The ED-A may
be the Extra Domain-A of human fibronectin.
[0066] ED-A is a 90 amino acid sequence which is inserted into
fibronectin (FN) by alternative splicing and is located between
domain 11 and 12 of FN (Borsi et al., 1987, J. Cell Biol., 104,
595-600). ED-A is mainly absent in the plasma form of FN but is
abundant during embryogenesis, tissue remodelling, fibrosis,
cardiac transplantation and solid tumour growth.
[0067] Alternative Splicing
[0068] Alternative splicing refers to the occurrence of different
patterns of splicing of a primary RNA transcript of DNA to produce
different mRNAs. After excision of introns, selection may determine
which exons are spliced together to form the mRNA. Alternative
splicing leads to production of different isoforms containing
different exons and/or different numbers of exons. For example one
isoform may comprise an additional amino acid sequence
corresponding to one or more exons, which may comprise one or more
domains.
[0069] Binding Member
[0070] This describes one member of a pair of molecules that bind
one another. The members of a binding pair may be naturally derived
or wholly or partially synthetically produced. One member of the
pair of molecules has an area on its surface, or a cavity, which
binds to and is therefore complementary to a particular spatial and
polar organization of the other member of the pair of molecules.
Examples of types of binding pairs are antigen-antibody,
biotin-avidin, hormone-hormone receptor, receptor-ligand,
enzyme-substrate. The present invention is concerned with
antigen-antibody type reactions.
[0071] A binding member normally comprises a molecule having an
antigen-binding site. For example, a binding member may be an
antibody molecule or a non-antibody protein that comprises an
antigen-binding site.
[0072] An antigen binding site may be provided by means of
arrangement of complementarity determining regions (CDRs) on
non-antibody protein scaffolds such as fibronectin or cytochrome B
etc. (Haan & Maggos, 2004; Koide 1998; Nygren 1997), or by
randomising or mutating amino acid residues of a loop within a
protein scaffold to confer binding specificity for a desired
target. Scaffolds for engineering novel binding sites in proteins
have been reviewed in detail by Nygren et al. (1997). Protein
scaffolds for antibody mimics are disclosed in WO/0034784, which is
herein incorporated by reference in its entirety, in which the
inventors describe proteins (antibody mimics) that include a
fibronectin type III domain having at least one randomised loop. A
suitable scaffold into which to graft one or more CDRs, e.g. a set
of HCDRs, may be provided by any domain member of the
immunoglobulin gene superfamily. The scaffold may be a human or
non-human protein. An advantage of a non-antibody protein scaffold
is that it may provide an antigen-binding site in a scaffold
molecule that is smaller and/or easier to manufacture than at least
some antibody molecules. Small size of a binding member may confer
useful physiological properties such as an ability to enter cells,
penetrate deep into tissues or reach targets within other
structures, or to bind within protein cavities of the target
antigen. Use of antigen binding sites in non-antibody protein
scaffolds is reviewed in Wess, 2004. Typical are proteins having a
stable backbone and one or more variable loops, in which the amino
acid sequence of the loop or loops is specifically or randomly
mutated to create an antigen-binding site that binds the target
antigen. Such proteins include the IgG-binding domains of protein A
from S. aureus, transferrin, tetranectin, fibronectin (e.g. 10th
fibronectin type III domain) and lipocalins. Other approaches
include synthetic "Microbodies" (Selecore GmbH), which are based on
cyclotides--small proteins having intra-molecular disulphide
bonds.
[0073] In addition to antibody sequences and/or an antigen-binding
site, a binding member for use in the present invention may
comprise other amino acids, e.g. forming a peptide or polypeptide,
such as a folded domain, or to impart to the molecule another
functional characteristic in addition to ability to bind antigen.
Binding members for use in the invention may carry a detectable
label, or may be conjugated to a toxin or a targeting moiety or
enzyme (e.g. via a peptidyl bond or linker). For example, a binding
member may comprise a catalytic site (e.g. in an enzyme domain) as
well as an antigen binding site, wherein the antigen binding site
binds to the antigen and thus targets the catalytic site to the
antigen. The catalytic site may inhibit biological function of the
antigen, e.g. by cleavage.
[0074] Although, as noted, CDRs can be carried by non-antibody
scaffolds, the structure for carrying a CDR or a set of CDRs will
generally be an antibody heavy or light chain sequence or
substantial portion thereof in which the CDR or set of CDRs is
located at a location corresponding to the CDR or set of CDRs of
naturally occurring VH and VL antibody variable domains encoded by
rearranged immunoglobulin genes. The structures and locations of
immunoglobulin variable domains may be determined by reference to
Kabat 1987, and updates thereof, now available on the Internet (at
immuno.bme.nwu.edu or find "Kabat" using any search engine).
[0075] By CDR region or CDR, it is intended to indicate the
hypervariable regions of the heavy and light chains of the
immunoglobulin as defined by Kabat et al. (1987), (Kabat 1991a, and
later editions). An antibody typically contains 3 heavy chain CDRs
and 3 light chain CDRs. The term CDR or CDRs is used here in order
to indicate, according to the case, one of these regions or
several, or even the whole, of these regions which contain the
majority of the amino acid residues responsible for the binding by
affinity of the antibody for the antigen or the epitope which it
recognizes.
[0076] Among the six short CDR sequences, the third CDR of the
heavy chain (HCDR3) has a greater size variability (greater
diversity essentially due to the mechanisms of arrangement of the
genes which give rise to it). It can be as short as 2 amino acids
although the longest size known is 26. Functionally, HCDR3 plays a
role in part in the determination of the specificity of the
antibody (Segal 1974; Amit 1986; Chothia 1987; Chothia 1989; Caton
1990; Sharon 1990a; Sharon 1990b; Kabat et al., 1991b).
[0077] Antibody Molecule
[0078] This describes an immunoglobulin whether natural or partly
or wholly synthetically produced. The term also relates to any
polypeptide or protein comprising an antibody antigen-binding site.
It must be understood here that the invention does not relate to
the antibodies in natural form, that is to say they are not in
their natural environment but that they have been able to be
isolated or obtained by purification from natural sources, or else
obtained by genetic recombination, or by chemical synthesis, and
that they can then contain unnatural amino acids as will be
described later. Antibody fragments that comprise an antibody
antigen-binding site include, but are not limited to, antibody
molecules such as Fab, Fab', Fab'-SH, scFv, Fv, dAb, Fd; and
diabodies.
[0079] It is possible to take monoclonal and other antibodies and
use techniques of recombinant DNA technology to produce other
antibodies or chimeric molecules that bind the target antigen. Such
techniques may involve introducing DNA encoding the immunoglobulin
variable region, or the CDRs, of an antibody to the constant
regions, or constant regions plus framework regions, of a different
immunoglobulin. See, for instance, EP-A-184187, GB 2188638A or
EP-A-239400, and a large body of subsequent literature. A hybridoma
or other cell producing an antibody may be subject to genetic
mutation or other changes, which may or may not alter the binding
specificity of antibodies produced.
[0080] As antibodies can be modified in a number of ways, the term
"antibody molecule" should be construed as covering any binding
member or substance having an antibody antigen-binding site with
the required specificity and/or binding to antigen. Thus, this term
covers antibody fragments and derivatives, including any
polypeptide comprising an antibody antigen-binding site, whether
natural or wholly or partially synthetic. Chimeric molecules
comprising an antibody antigen-binding site, or equivalent, fused
to another polypeptide (e.g. derived from another species or
belonging to another antibody class or subclass) are therefore
included. Cloning and expression of chimeric antibodies are
described in EP-A-0120694 and EP-A-0125023, and a large body of
subsequent literature.
[0081] Further techniques available in the art of antibody
engineering have made it possible to isolate human and humanised
antibodies. For example, human hybridomas can be made as described
by Kontermann & Dubel (2001). Phage display, another
established technique for generating binding members has been
described in detail in many publications such as WO92/01047
(discussed further below) and U.S. Pat. Nos. 5,969,108, 5,565,332,
5,733,743, 5,858,657, 5,871,907, 5,872,215, 5,885,793, 5,962,255,
6,140,471, 6,172,197, 6,225,447, 6,291,650, 6,492,160, 6,521,404
and Kontermann & Dubel (2001). Transgenic mice in which the
mouse antibody genes are inactivated and functionally replaced with
human antibody genes while leaving intact other components of the
mouse immune system, can be used for isolating human antibodies
(Mendez 1997).
[0082] Synthetic antibody molecules may be created by expression
from genes generated by means of oligonucleotides synthesized and
assembled within suitable expression vectors, for example as
described by Knappik et al. (2000) or Krebs et al. (2001).
[0083] It has been shown that fragments of a whole antibody can
perform the function of binding antigens. Examples of binding
fragments are (i) the Fab fragment consisting of VL, VH, CL and CH1
domains; (ii) the Fd fragment consisting of the VH and CH1 domains;
(iii) the Fv fragment consisting of the VL and VH domains of a
single antibody; (iv) the dAb fragment (Ward 1989; McCafferty 1990;
Holt 2003), which consists of a VH or a VL domain; (v) isolated CDR
regions; (vi) F(ab')2 fragments, a bivalent fragment comprising two
linked Fab fragments (vii) single chain Fv molecules (scFv),
wherein a VH domain and a VL domain are linked by a peptide linker
which allows the two domains to associate to form an antigen
binding site (Bird 1988; Huston 1988); (viii) bispecific single
chain Fv dimers (PCT/US92/09965) and (ix) "diabodies", multivalent
or multispecific fragments constructed by gene fusion (WO94/13804;
Holliger 1993a). Fv, scFv or diabody molecules may be stabilized by
the incorporation of disulphide bridges linking the VH and VL
domains (Reiter 1996). Minibodies comprising a scFv joined to a CH3
domain may also be made (Hu 1996). Other examples of binding
fragments are Fab', which differs from Fab fragments by the
addition of a few residues at the carboxyl terminus of the heavy
chain CH1 domain, including one or more cysteines from the antibody
hinge region, and Fab'-SH, which is a Fab' fragment in which the
cysteine residue(s) of the constant domains bear a free thiol
group.
[0084] Antibody fragments for use in the invention can be obtained
starting from any of the antibody molecules described herein, e.g.
antibody molecules comprising VH and/or VL domains or CDRs of any
of antibodies described herein, by methods such as digestion by
enzymes, such as pepsin or papain and/or by cleavage of the
disulfide bridges by chemical reduction. In another manner,
antibody fragments of the present invention may be obtained by
techniques of genetic recombination likewise well known to the
person skilled in the art or else by peptide synthesis by means of,
for example, automatic peptide synthesizers such as those supplied
by the company Applied Biosystems, etc., or by nucleic acid
synthesis and expression.
[0085] Functional antibody fragments according to the present
invention include any functional fragment whose half-life is
increased by a chemical modification, especially by PEGylation, or
by incorporation in a liposome.
[0086] A dAb (domain antibody) is a small monomeric antigen-binding
fragment of an antibody, namely the variable region of an antibody
heavy or light chain (Holt 2003). VH dAbs occur naturally in
camelids (e.g. camel, llama) and may be produced by immunizing a
camelid with a target antigen, isolating antigen-specific B cells
and directly cloning dAb genes from individual B cells. dAbs are
also producible in cell culture. Their small size, good solubility
and temperature stability makes them particularly physiologically
useful and suitable for selection and affinity maturation. A
binding member of the present invention may be a dAb comprising a
VH or VL domain substantially as set out herein, or a VH or VL
domain comprising a set of CDRs substantially as set out
herein.
[0087] As used herein, the phrase "substantially as set out" refers
to the characteristic(s) of the relevant CDRs of the VH or VL
domain of binding members described herein will be either identical
or highly similar to the specified regions of which the sequence is
set out herein. As described herein, the phrase "highly similar"
with respect to specified region(s) of one or more variable
domains, it is contemplated that from 1 to about 5, e.g. from 1 to
4, including 1 to 3, or 1 or 2, or 3 or 4, amino acid substitutions
may be made in the CDR and/or VH or VL domain.
[0088] Bispecific or bifunctional antibodies form a second
generation of monoclonal antibodies in which two different variable
regions are combined in the same molecule (Holliger 1999). Their
use has been demonstrated both in the diagnostic field and in the
therapy field from their capacity to recruit new effector functions
or to target several molecules on the surface of tumor cells. Where
bispecific antibodies are to be used, these may be conventional
bispecific antibodies, which can be manufactured in a variety of
ways (Holliger 1993b), e.g. prepared chemically or from hybrid
hybridomas, or may be any of the bispecific antibody fragments
mentioned above. These antibodies can be obtained by chemical
methods (Glennie 1987; Repp 1995) or somatic methods (Staerz 1986;
Suresh 1986) but likewise by genetic engineering techniques which
allow the heterodimerization to be forced and thus facilitate the
process of purification of the antibody sought (Merchand 1998).
Examples of bispecific antibodies include those of the BiTE.TM.
technology in which the binding domains of two antibodies with
different specificity can be used and directly linked via short
flexible peptides. This combines two antibodies on a short single
polypeptide chain. Diabodies and scFv can be constructed without an
Fc region, using only variable domains, potentially reducing the
effects of anti-idiotypic reaction.
[0089] Bispecific antibodies can be constructed as entire IgG, as
bispecific Fab'2, as Fab'PEG, as diabodies or else as bispecific
scFv. Further, two bispecific antibodies can be linked using
routine methods known in the art to form tetravalent
antibodies.
[0090] Bispecific diabodies, as opposed to bispecific whole
antibodies, may also be particularly useful because they can be
readily constructed and expressed in E. coli. Diabodies (and many
other polypeptides such as antibody fragments) of appropriate
binding specificities can be readily selected using phage display
(WO94/13804) from libraries. If one arm of the diabody is to be
kept constant, for instance, with a specificity directed against a
target antigen, then a library can be made where the other arm is
varied and an antibody of appropriate specificity selected.
Bispecific whole antibodies may be made by alternative engineering
methods as described in Ridgeway 1996.
[0091] Various methods are available in the art for obtaining
antibodies against a target antigen. The antibodies may be
monoclonal antibodies, especially of human, murine, chimeric or
humanized origin, which can be obtained according to the standard
methods well known to the person skilled in the art.
[0092] In general, for the preparation of monoclonal antibodies or
their functional fragments, especially of murine origin, it is
possible to refer to techniques which are described in particular
in the manual "Antibodies" (Harlow and Lane 1988) or to the
technique of preparation from hybridomas described by Kohler and
Milstein, 1975.
[0093] Monoclonal antibodies can be obtained, for example, from an
animal cell immunized against A-FN, or one of its fragments
containing the epitope recognized by said monoclonal antibodies,
e.g. a fragment comprising or consisting of ED-A, or a peptide
fragment of ED-A. The A-FN, or one of its fragments, can especially
be produced according to the usual working methods, by genetic
recombination starting with a nucleic acid sequence contained in
the cDNA sequence coding for A-FN or fragment thereof, by peptide
synthesis starting from a sequence of amino acids comprised in the
peptide sequence of the A-FN and/or fragment thereof.
[0094] Monoclonal antibodies can, for example, be purified on an
affinity column on which A-FN or one of its fragments containing
the epitope recognized by said monoclonal antibodies, e.g. a
fragment comprising or consisting of ED-A or a peptide fragment of
ED-A, has previously been immobilized. Monoclonal antibodies can be
purified by chromatography on protein A and/or G, followed or not
followed by ion-exchange chromatography aimed at eliminating the
residual protein contaminants as well as the DNA and the LPS, in
itself, followed or not followed by exclusion chromatography on
Sepharose gel in order to eliminate the potential aggregates due to
the presence of dimers or of other multimers. The whole of these
techniques may be used simultaneously or successively.
[0095] Antigen-Binding Site
[0096] This describes the part of a molecule that binds to and is
complementary to all or part of the target antigen. In an antibody
molecule it is referred to as the antibody antigen-binding site,
and comprises the part of the antibody that binds to and is
complementary to all or part of the target antigen. Where an
antigen is large, an antibody may only bind to a particular part of
the antigen, which part is termed an epitope. An antibody
antigen-binding site may be provided by one or more antibody
variable domains. An antibody antigen-binding site may comprise an
antibody light chain variable region (VL) and an antibody heavy
chain variable region (VH).
[0097] Isolated
[0098] This refers to the state in which binding members for use in
the invention or nucleic acid encoding such binding members, will
generally be in accordance with the present invention. Thus,
binding members, VH and/or VL domains of the present invention may
be provided isolated and/or purified, e.g. from their natural
environment, in substantially pure or homogeneous form, or, in the
case of nucleic acid, free or substantially free of nucleic acid or
genes of origin other than the sequence encoding a polypeptide with
the required function. Isolated members and isolated nucleic acid
will be free or substantially free of material with which they are
naturally associated such as other polypeptides or nucleic acids
with which they are found in their natural environment, or the
environment in which they are prepared (e.g. cell culture) when
such preparation is by recombinant DNA technology practised in
vitro or in vivo. Members and nucleic acid may be formulated with
diluents or adjuvants and still for practical purposes be
isolated--for example the members will normally be mixed with
gelatin or other carriers if used to coat microtitre plates for use
in immunoassays, or will be mixed with pharmaceutically acceptable
carriers or diluents when used in diagnosis or therapy. Binding
members may be glycosylated, either naturally or by systems of
heterologous eukaryotic cells (e.g. CHO or NS0 (ECACC 85110503)
cells, or they may be (for example if produced by expression in a
prokaryotic cell) unglycosylated.
[0099] Heterogeneous preparations comprising antibody molecules may
also be used in the invention. For example, such preparations may
be mixtures of antibodies with full-length heavy chains and heavy
chains lacking the C-terminal lysine, with various degrees of
glycosylation and/or with derivatized amino acids, such as
cyclization of an N-terminal glutamic acid to form a pyroglutamic
acid residue.
[0100] One or more binding members for an antigen, e.g. the A-FN or
the ED-A of fibronectin, may be obtained by bringing into contact a
library of binding members according to the invention and the
antigen or a fragment thereof, e.g. a fragment comprising or
consisting of ED-A or a peptide fragment of ED-A and selecting one
or more binding members of the library able to bind the
antigen.
[0101] An antibody library may be screened using Iterative Colony
Filter Screening (ICFS). In ICFS, bacteria containing the DNA
encoding several binding specificities are grown in a liquid medium
and, once the stage of exponential growth has been reached, some
billions of them are distributed onto a growth support consisting
of a suitably pre-treated membrane filter which is incubated until
completely confluent bacteriae colonies appear. A second trap
substrate consists of another membrane filter, pre-humidified and
covered with the desired antigen.
[0102] The trap membrane filter is then placed onto a plate
containing a suitable culture medium and covered with the growth
filter with the surface covered with bacterial colonies pointing
upwards. The sandwich thus obtained is incubated at room
temperature for about 16 h. It is thus possible to obtain the
expression of the genes encoding antibody fragments scFv having a
spreading action, so that those fragments binding specifically with
the antigen which is present on the trap membrane are trapped. The
trap membrane is then treated to point out bound antibody fragments
scFv with colorimetric techniques commonly used to this
purpose.
[0103] The position of the coloured spots on the trap filter allows
to go back to the corresponding bacterial colonies which are
present on the growth membrane and produced the antibody fragments
trapped. Such colonies are gathered and grown and the bacteria-a
few millions of them are distributed onto a new culture membrane
repeating the procedures described above. Analogous cycles are then
carried out until the positive signals on the trap membrane
correspond to single positive colonies, each of which represents a
potential source of monoclonal antibody fragments directed against
the antigen used in the selection. ICFS is described in e.g.
WO0246455, which is incorporated herein by reference. A library may
also be displayed on particles or molecular complexes, e.g.
replicable genetic packages such bacteriophage (e.g. T7) particles,
or other in vitro display systems, each particle or molecular
complex containing nucleic acid encoding the antibody VH variable
domain displayed on it, and optionally also a displayed VL domain
if present. Phage display is described in WO92/01047 and e.g. U.S.
Pat. Nos. 5,969,108, 5,565,332, 5,733,743, 5,858,657, 5,871,907,
5,872,215, 5,885,793, 5,962,255, 6,140,471, 6,172,197, 6,225,447,
6,291,650, 6,492,160 and 6,521,404, each of which is herein
incorporated by reference in its entirety.
[0104] Following selection of binding members able to bind the
antigen and displayed on bacteriophage or other library particles
or molecular complexes, nucleic acid may be taken from a
bacteriophage or other particle or molecular complex displaying a
said selected binding member. Such nucleic acid may be used in
subsequent production of a binding member or an antibody VH or VL
variable domain by expression from nucleic acid with the sequence
of nucleic acid taken from a bacteriophage or other particle or
molecular complex displaying a said selected binding member.
[0105] An antibody VH variable domain with the amino acid sequence
of an antibody VH variable domain of a said selected binding member
may be provided in isolated form, as may a binding member
comprising such a VH domain.
[0106] Ability to bind the A-FN or the ED-A of fibronectin or other
target antigen or isoform may be further tested, e.g. ability to
compete with e.g. any one of anti-ED-A antibodies H1, B2, C5, D5,
E5, C8, F8, F1, B7, E8 or G9 for binding to the A-FN or a fragment
of the A-FN, e.g. the ED-A of fibronectin.
[0107] A binding member for use in the invention may bind the A-FN
and/or the ED-A of fibronectin specifically. A binding member of
the present invention may bind the A-FN and/or the ED-A of
fibronectin with the same affinity as anti-ED-A antibody H1, B2,
C5, D5, E5, C8, F8, F1, B7, E8 or G9, e.g. in scFv format, or with
an affinity that is better. A binding member for use in the
invention may bind the A-FN and/or the ED-A of fibronectin with a
K.sub.D of 3.times.10.sup.-8 M or an affinity that is better.
Preferably, a binding member for use in the invention binds the
A-FN and/or the ED-A of fibronectin with a K.sub.D of
2.times.10.sup.-8 M or an affinity that is better. More preferably,
a binding member for use in the invention binds the A-FN and/or the
ED-A of fibronectin with a K.sub.D of 1.7.times.10.sup.-8 M or an
affinity that is better. Yet more preferably, a binding member for
use in the invention binds the A-FN and/or the ED-A of fibronectin
with a K.sub.D of 1.4.times.10.sup.-8 M or an affinity that is
better. Most preferably, a binding member for use in the invention
binds the A-FN and/or the ED-A of fibronectin with a K.sub.D of
3.times.10.sup.-9 M or an affinity that is better.
[0108] A binding member of the present invention may bind to the
same epitope on A-FN and/or the ED-A of fibronectin as anti-ED-A
antibody H1, B2, C5, D5, E5, C8, F8, F1, B7, E8 or G9.
[0109] A binding member for use in the invention may not show any
significant binding to molecules other than the A-FN and/or the
ED-A of fibronectin. In particular the binding member may not bind
other isoforms of fibronectin, for example the ED-B isoform and/or
the IIICS isoform of fibronectin.
[0110] Variants of antibody molecules disclosed herein may be
produced and used in the present invention. The techniques required
to make substitutions within amino acid sequences of CDRs, antibody
VH or VL domains and binding members generally are available in the
art. Variant sequences may be made, with substitutions that may or
may not be predicted to have a minimal or beneficial effect on
activity, and tested for ability to bind A-FN and/or the ED-A of
fibronectin and/or for any other desired property.
[0111] Variable domain amino acid sequence variants of any of the
VH and VL domains whose sequences are specifically disclosed herein
may be employed in accordance with the present invention, as
discussed. Particular variants may include one or more amino acid
sequence alterations (addition, deletion, substitution and/or
insertion of an amino acid residue), may be less than about 20
alterations, less than about 15 alterations, less than about 10
alterations or less than about 5 alterations, maybe 5, 4, 3, 2 or
1. Alterations may be made in one or more framework regions and/or
one or more CDRs. The alterations normally do not result in loss of
function, so a binding member comprising a thus-altered amino acid
sequence may retain an ability to bind A-FN and/or the ED-A of
fibronectin. For example, it may retain the same quantitative
binding as a binding member in which the alteration is not made,
e.g. as measured in an assay described herein. The binding member
comprising a thus-altered amino acid sequence may have an improved
ability to bind A-FN and/or the ED-A of fibronectin.
[0112] Novel VH or VL regions carrying CDR-derived sequences for
use in the invention may be generated using random mutagenesis of
one or more selected VH and/or VL genes to generate mutations
within the entire variable domain. In some embodiments one or two
amino acid substitutions are made within an entire variable domain
or set of CDRs. Another method that may be used is to direct
mutagenesis to CDR regions of VH or VL genes.
[0113] As noted above, a CDR amino acid sequence substantially as
set out herein may be carried as a CDR in a human antibody variable
domain or a substantial portion thereof. The HCDR3 sequences
substantially as set out herein represent embodiments of the
present invention and for example each of these may be carried as a
HCDR3 in a human heavy chain variable domain or a substantial
portion thereof.
[0114] Variable domains employed in the invention may be obtained
or derived from any germ-line or rearranged human variable domain,
or may be a synthetic variable domain based on consensus or actual
sequences of known human variable domains. A variable domain can be
derived from a non-human antibody. A CDR sequence for use in the
invention (e.g. CDR3) may be introduced into a repertoire of
variable domains lacking a CDR (e.g. CDR3), using recombinant DNA
technology. For example, Marks et al. (1992) describe methods of
producing repertoires of antibody variable domains in which
consensus primers directed at or adjacent to the 5' end of the
variable domain area are used in conjunction with consensus primers
to the third framework region of human VH genes to provide a
repertoire of VH variable domains lacking a CDR3. Marks et al.
further describe how this repertoire may be combined with a CDR3 of
a particular antibody. Using analogous techniques, the CDR3-derived
sequences of the present invention may be shuffled with repertoires
of VH or VL domains lacking a CDR3, and the shuffled complete VH or
VL domains combined with a cognate VL or VH domain to provide
binding members for use in the invention. The repertoire may then
be displayed in a suitable host system such as the phage display
system of WO92/01047, which is herein incorporated by reference in
its entirety, or any of a subsequent large body of literature,
including Kay, Winter & McCafferty (1996), so that suitable
binding members may be selected. A repertoire may consist of from
anything from 10.sup.4 individual members upwards, for example at
least 10.sup.5, at least 10.sup.6, at least 10.sup.7, at least
10.sup.8, at least 10.sup.9 or at least 10.sup.10 members.
[0115] Similarly, one or more, or all three CDRs may be grafted
into a repertoire of VH or VL domains that are then screened for a
binding member or binding members for the A-FN and/or the ED-A of
fibronectin.
[0116] One or more of the HCDR1, HCDR2 and HCDR3 of antibody H1,
B2, C5, D5, E5, C8, F8, F1, B7, E8 or G9, or the set of HCDRs may
be employed, and/or one or more of the X LCDR1, LCDR2 and LCDR3 of
antibody H1, B2, C5, D5, E5, C8, F8, F1, B7, E8 or G9 or the set of
LCDRs of antibody H1, B2, C5, D5, E5, C8, F8, F1, B7, E8 or G9 may
be employed.
[0117] Similarly, other VH and VL domains, sets of CDRs and sets of
HCDRs and/or sets of LCDRs disclosed herein may be employed.
[0118] The A-FN and/or the ED-A of fibronectin may be used in a
screen for binding members, e.g. antibody molecules, for use in the
preparation of a medicament for the treatment of rheumatoid
arthritis. The screen may a screen of a repertoire as disclosed
elsewhere herein.
[0119] A substantial portion of an immunoglobulin variable domain
may comprise at least the three CDR regions, together with their
intervening framework regions. The portion may also include at
least about 50% of either or both of the first and fourth framework
regions, the 50% being the C-terminal 50% of the first framework
region and the N-terminal 50% of the fourth framework region.
[0120] Additional residues at the N-terminal or C-terminal end of
the substantial part of the variable domain may be those not
normally associated with naturally occurring variable domain
regions. For example, construction of binding members of the
present invention made by recombinant DNA techniques may result in
the introduction of N- or C-terminal residues encoded by linkers
introduced to facilitate cloning or other manipulation steps. Other
manipulation steps include the introduction of linkers to join
variable domains disclosed elsewhere herein to further protein
sequences including antibody constant regions, other variable
domains (for example in the production of diabodies) or
detectable/functional labels as discussed in more detail elsewhere
herein.
[0121] Although binding members may comprise a pair of VH and VL
domains, single binding domains based on either VH or VL domain
sequences may also be used in the invention. It is known that
single immunoglobulin domains, especially VH domains, are capable
of binding target antigens in a specific manner. For example, see
the discussion of dAbs above.
[0122] In the case of either of the single binding domains, these
domains may be used to screen for complementary domains capable of
forming a two-domain binding member able to bind A-FN and/or the
ED-A of fibronectin. This may be achieved by phage display
screening methods using the so-called hierarchical dual
combinatorial approach as disclosed in WO92/01047, herein
incorporated by reference in its entirety, in which an individual
colony containing either an H or L chain clone is used to infect a
complete library of clones encoding the other chain (L or H) and
the resulting two-chain binding member is selected in accordance
with phage display techniques such as those described in that
reference. This technique is also disclosed in Marks 1992.
[0123] Binding members for use in the present invention may further
comprise antibody constant regions or parts thereof, e.g. human
antibody constant regions or parts thereof. For example, a VL
domain may be attached at its C-terminal end to antibody light
chain constant domains including human C.kappa. or C.lamda. chains,
e.g. C.lamda.. Similarly, a binding member based on a VH domain may
be attached at its C-terminal end to all or part (e.g. a CH1
domain) of an immunoglobulin heavy chain derived from any antibody
isotype, e.g. IgG, IgA, IgE and IgM and any of the isotype
sub-classes, particularly IgG1 and IgG4. Any synthetic or other
constant region variant that has these properties and stabilizes
variable regions is also useful in embodiments of the present
invention.
[0124] Binding members for use in the invention may be labelled
with a detectable or functional label. A label can be any molecule
that produces or can be induced to produce a signal, including but
not limited to fluorescers, radiolabels, enzymes, chemiluminescers
or photosensitizers. Thus, binding may be detected and/or measured
by detecting fluorescence or luminescence, radioactivity, enzyme
activity or light absorbance. Detectable labels may be attached to
antibodies for use in the invention using conventional chemistry
known in the art.
[0125] There are numerous methods by which the label can produce a
signal detectable by external means, for example, by visual
examination, electromagnetic radiation, heat, and chemical
reagents. The label can also be bound to another binding member
that binds the antibody for use in the invention, or to a
support.
[0126] Labelled binding members, e.g. scFv labelled with a
detectable label, may be used diagnostically in vivo, ex vivo or in
vitro, and/or therapeutically.
[0127] For example, radiolabelled binding members (e.g. binding
members conjugated to a radioisotope) may be used in radiodiagnosis
and radiotherapy. Radioisotopes which may be conjugated to a
binding member for use in the invention include isotopes such as
.sup.94mTc, .sup.99mTc, .sup.186Re, .sup.188Re, .sup.203Pb,
.sup.67Ga, .sup.68Ga, .sup.47Sc, .sup.111In, .sup.97Ru, .sup.62Cu,
.sup.64Cu, .sup.86Y, .sup.88Y, .sup.90Y, .sup.121Sn, .sup.161Tb,
.sup.153Sm, .sup.166Ho, .sup.105Rh, .sup.177Lu, .sup.123I,
.sup.124I, .sup.125I and .sup.131I.
[0128] For example, a binding member for use in the invention
labelled with a detectable label may be used to detect, diagnose or
monitor rheumatoid arthritis in a human or animal.
[0129] A binding member of the present invention may be used for
the manufacture of a diagnostic product for use in diagnosing
rheumatoid arthritis.
[0130] The present invention provides a method of detecting or
diagnosing rheumatoid arthritis in a human or animal comprising:
[0131] (a) administering to the human or animal a binding member of
the present invention, for example labelled with a detectable
label, which binds the ED-A isoform of fibronectin and/or the ED-A
of fibronectin, and [0132] (b) determining the presence or absence
of the binding member in neovasculature of the human or animal
body;
[0133] wherein localisation of the binding member to neovasculature
in the human or animal is indicative of the presence of rheumatoid
arthritis.
[0134] Where the binding member is labelled with a detectable
label, the presence or absence of the detectable label may be
determined by detecting the label.
[0135] A conjugate or fusion between a binding member for use in
the invention and a molecule that exerts a biocidal, cytotoxic
immunosuppressive or anti-inflammatory effect on target cells in
the lesions and an antibody directed against an extracellular
matrix component which is present in such lesions may be employed
in the present invention. For example, the conjugated molecule may
be inter alia interleukin-10, an anti-inflammatory or other drug, a
photosensitizer or a radionuclide. Such conjugates may be used
therapeutically, e.g. for treatment of rheumatoid arthritis as
referred to herein.
[0136] Production and use of fusions or conjugates of binding
members with biocidal or cytotoxic molecules is described for
example in WO01/62298, which is incorporated by reference
herein.
[0137] The invention provides a method of treating rheumatoid
arthritis, the method comprising administering to an individual a
therapeutically effective amount of a medicament comprising a
binding member for use in the invention.
[0138] The binding member may be a conjugate of (i) a molecule
which exerts an anti-inflammatory effect on target cells by
cellular interaction, an anti-inflammatory molecule, IL-10, TGF
beta, or other drug, and (ii) a binding member for the ED-A isoform
of fibronectin and/or the ED-A of fibronectin.
[0139] The binding member may be a conjugate of (i) a molecule
which exerts an immunosuppressive or anti-inflammatory effect and
(ii) a binding member for the ED-A isoform of fibronectin and/or
the ED-A of fibronectin.
[0140] The binding member may be a conjugate of (i) interleukin-10
(IL10) or TGF beta and (ii) a binding member for the ED-A isoform
of fibronectin and/or the ED-A of fibronectin. Such a binding
member is useful in aspects of the invention disclosed herein
relating to treatment of rheumatoid arthritis.
[0141] The invention provides the use of a binding member for use
in the invention for the preparation of a medicament for the
treatment of rheumatoid arthritis.
[0142] The binding member may be a conjugated or fused to a
molecule that exerts a biocidal, cytotoxic, immunosuppressive or
anti-inflammatory effect as described herein. The binding member
may be a conjugate of (i) a molecule which exerts a biocidal or
cytotoxic effect on target cells by cellular interaction or has an
immunosuppressive or anti-inflammatory effect and (ii) a binding
member for human fibronectin according to the present
invention.
[0143] Also described herein is a conjugate of (i) a molecule which
exerts a biocidal or cytotoxic effect on target cells by cellular
interaction, or an immunosuppressive or anti-inflammatory effect
and (ii) a binding member for human fibronectin according for use
in the present invention. Such a conjugate preferably comprises a
fusion protein comprising the biocidal, cytotoxic,
immunosuppressive or anti-inflammatory molecule and a said binding
member, or, where the binding member is two-chain or multi-chain, a
fusion protein comprising the biocidal, cytotoxic,
immunosuppressive or anti-inflammatory molecule and a polypeptide
chain component of said binding member. Preferably the binding
member is a single-chain polypeptide, e.g. a single-chain antibody
molecule, such as scFv.
[0144] A fusion protein comprising the immunosuppressive or
anti-inflammatory molecule and a single-chain Fv antibody molecule
may be used in the invention.
[0145] The immunosuppressive or anti-inflammatory molecule that
exerts its effect on target cells by cellular interaction, may
interact directly with the target cells, may interact with a
membrane-bound receptor on the target cell or perturb the
electrochemical potential of the cell membrane. In an exemplary
preferred embodiment the molecule is IL-10.
[0146] As discussed further below, the specific binding member is
preferably an antibody or comprises an antibody antigen-binding
site. Conveniently, the specific binding member may be a
single-chain polypeptide, such as a single-chain antibody. This
allows for convenient production of a fusion protein comprising
single-chain antibody and immunosuppressive or anti-inflammatory
molecule (e.g. interleukin-10 or TGF beta. An antibody
antigen-binding site may be provided by means of association of an
antibody VH domain and an antibody VL domain in separate
polypeptides, e.g. in a complete antibody or in an antibody
fragment such as Fab or diabody. Where the specific binding member
is a two-chain or multi-chain molecule (e.g. Fab or whole antibody,
respectively), the immunosuppressive or anti-inflammatory molecule
may be conjugated as a fusion polypeptide with one or more
polypeptide chains in the specific binding member.
[0147] The binding member may be conjugated with the
immunosuppressive or anti-inflammatory molecule by means of a
peptide bond, i.e. within a fusion polypeptide comprising said
molecule and the specific binding member or a polypeptide chain
component thereof (see e.g. Trachsel et al.). Other means for
conjugation include chemical conjugation, especially cross-linking
using a bifunctional reagent (e.g. employing DOUBLE-REAGENTS.TM.
Cross-linking Reagents Selection Guide, Pierce).
[0148] Also described herein is isolated nucleic acid encoding a
binding member for use in the present invention. Nucleic acid may
include DNA and/or RNA. A nucleic acid may code for a CDR or set of
CDRs or VH domain or VL domain or antibody antigen-binding site or
antibody molecule, e.g. scFv or IgG, e.g. IgG1, as defined above.
The nucleotide sequences may encode the VH and/or VL domains
disclosed herein.
[0149] Further described herein are constructs in the form of
plasmids, vectors, transcription or expression cassettes which
comprise at least one polynucleotide as described above.
[0150] A recombinant host cell that comprises one or more
constructs as above are also described. A nucleic acid encoding any
CDR or set of CDRs or VH domain or VL domain or antibody
antigen-binding site or antibody molecule, e.g. scFv or IgG1 or
IgG4 as provided, is described, as is a method of production of the
encoded product, which method comprises expression from encoding
nucleic acid. Expression may conveniently be achieved by culturing
under appropriate conditions recombinant host cells containing the
nucleic acid. Following production by expression a VH or VL domain,
or binding member may be isolated and/or purified using any
suitable technique, then used as appropriate.
[0151] A nucleic acid may comprise DNA or RNA and may be wholly or
partially synthetic. Reference to a nucleotide sequence as set out
herein encompasses a DNA molecule with the specified sequence, and
encompasses a RNA molecule with the specified sequence in which U
is substituted for T, unless context requires otherwise.
[0152] A method of production of an antibody VH variable domain,
the method including causing expression from encoding nucleic acid
is also described. Such a method may comprise culturing host cells
under conditions for production of said antibody VH variable
domain.
[0153] A method of production may comprise a step of isolation
and/or purification of the product. A method of production may
comprise formulating the product into a composition including at
least one additional component, such as a pharmaceutically
acceptable excipient.
[0154] Systems for cloning and expression of a polypeptide in a
variety of different host cells are well known. Suitable host cells
include bacteria, mammalian cells, plant cells, filamentous fungi,
yeast and baculovirus systems and transgenic plants and animals.
The expression of antibodies and antibody fragments in prokaryotic
cells is well established in the art. For a review, see for example
Pluckthun 1991. A common bacterial host is E. coli.
[0155] Expression in eukaryotic cells in culture is also available
to those skilled in the art as an option for production of a
binding member for example Chadd & Chamow (2001), Andersen
& Krummen (2002), Larrick & Thomas (2001). Mammalian cell
lines available in the art for expression of a heterologous
polypeptide include Chinese hamster ovary (CHO) cells, HeLa cells,
baby hamster kidney cells, NS0 mouse melanoma cells, YB2/0 rat
myeloma cells, human embryonic kidney cells, human embryonic retina
cells and many others.
[0156] Suitable vectors can be chosen or constructed, containing
appropriate regulatory sequences, including promoter sequences,
terminator sequences, polyadenylation sequences, enhancer
sequences, marker genes and other sequences as appropriate. Vectors
may be plasmids e.g. phagemid, or viral e.g. `phage, as
appropriate. For further details see, for example, Sambrook &
Russell (2001). Many known techniques and protocols for
manipulation of nucleic acid, for example in preparation of nucleic
acid constructs, mutagenesis, sequencing, introduction of DNA into
cells and gene expression, and analysis of proteins, are described
in detail in Ausubel 1999.
[0157] A host cell may contain a nucleic acid as described herein.
Such a host cell may be in vitro and may be in culture. Such a host
cell may be in vivo. In vivo presence of the host cell may allow
intracellular expression of a binding member for use in the present
invention as "intrabodies" or intracellular antibodies. Intrabodies
may be used for gene therapy.
[0158] A method comprising introducing a nucleic acid disclosed
herein into a host cell is also described. The introduction may
employ any available technique. For eukaryotic cells, suitable
techniques may include calcium phosphate transfection,
DEAE-Dextran, electroporation, liposome-mediated transfection and
transduction using retrovirus or other virus, e.g. vaccinia or, for
insect cells, baculovirus. Introducing nucleic acid in the host
cell, in particular a eukaryotic cell may use a viral or a plasmid
based system. The plasmid system may be maintained episomally or
may be incorporated into the host cell or into an artificial
chromosome. Incorporation may be either by random or targeted
integration of one or more copies at single or multiple loci. For
bacterial cells, suitable techniques may include calcium chloride
transformation, electroporation and transfection using
bacteriophage.
[0159] The introduction may be followed by causing or allowing
expression from the nucleic acid, e.g. by culturing host cells
under conditions for expression of the gene. The purification of
the expressed product may be achieved by methods known to one of
skill in the art.
[0160] The nucleic acid may be integrated into the genome (e.g.
chromosome) of the host cell. Integration may be promoted by
inclusion of sequences that promote recombination with the genome,
in accordance with standard techniques.
[0161] A method that comprises using a construct as stated above in
an expression system in order to express a binding member or
polypeptide as above is also described.
[0162] Binding members for use in the present invention are
designed to be used in methods of diagnosis or treatment in human
or animal subjects, e.g. human. Binding members for use in the
invention may be used in diagnosis or treatment of rheumatoid
arthritis.
[0163] Accordingly, the invention provides methods of treatment
comprising administration of a binding member as provided,
pharmaceutical compositions comprising such a binding member, and
use of such a binding member in the manufacture of a medicament for
administration, for example in a method of making a medicament or
pharmaceutical composition comprising formulating the binding
member with a pharmaceutically acceptable excipient.
Pharmaceutically acceptable vehicles are well known and will be
adapted by the person skilled in the art as a function of the
nature and of the mode of administration of the active compound(s)
chosen.
[0164] Binding members for use in the present invention will
usually be administered in the form of a pharmaceutical
composition, which may comprise at least one component in addition
to the binding member. Thus pharmaceutical compositions according
to the present invention, and for use in accordance with the
present invention, may comprise, in addition to active ingredient,
a pharmaceutically acceptable excipient, carrier, buffer,
stabilizer or other materials well known to those skilled in the
art. Such materials should be non-toxic and should not interfere
with the efficacy of the active ingredient. The precise nature of
the carrier or other material will depend on the route of
administration, which may be oral, inhaled or by injection, e.g.
intravenous.
[0165] Pharmaceutical compositions for oral administration such as
for example nanobodies etc are also envisaged in the present
invention. Such oral formulations may be in tablet, capsule,
powder, liquid or semi-solid form. A tablet may comprise a solid
carrier such as gelatin or an adjuvant. Liquid pharmaceutical
compositions generally comprise a liquid carrier such as water,
petroleum, animal or vegetable oils, mineral oil or synthetic oil.
Physiological saline solution, dextrose or other saccharide
solution or glycols such as ethylene glycol, propylene glycol or
polyethylene glycol may be included.
[0166] For intravenous injection, or injection at the site of
affliction, the active ingredient will be in the form of a
parenterally acceptable aqueous solution which is pyrogen-free and
has suitable pH, isotonicity and stability. Those of relevant skill
in the art are well able to prepare suitable solutions using, for
example, isotonic vehicles such as Sodium Chloride Injection,
Ringer's Injection, Lactated Ringer's Injection. Preservatives,
stabilizers, buffers, antioxidants and/or other additives may be
employed, as required. Many methods for the preparation of
pharmaceutical formulations are known to those skilled in the art.
See e.g. Robinson, 1978.
[0167] A composition may be administered alone or in combination
with other treatments, concurrently or sequentially or as a
combined preparation with another therapeutic agent or agents,
dependent upon the condition to be treated.
[0168] A binding member for use in the present invention may be
used as part of a combination therapy in conjunction with an
additional medicinal component. Combination treatments may be used
to provide significant synergistic effects, particularly the
combination of a binding member for use in the present invention
with one or more other drugs. A binding member for use in the
present invention may be administered concurrently or sequentially
or as a combined preparation with another therapeutic agent or
agents, for the treatment of one or more of the conditions listed
herein.
[0169] For example, a binding member for use in the invention may
be used in combination with an existing therapeutic agent for the
treatment of rheumatoid arthritis.
[0170] Existing therapeutic agents for the treatment of rheumatoid
arthritis include IL-10, TGFbeta, photosensitizers and cytotoxic
drugs.
[0171] A binding member for use in the invention and one or more of
the above additional medicinal components may be used in the
manufacture of a medicament. The medicament may be for separate or
combined administration to an individual, and accordingly may
comprise the binding member and the additional component as a
combined preparation or as separate preparations. Separate
preparations may be used to facilitate separate and sequential or
simultaneous administration, and allow administration of the
components by different routes e.g. oral and parenteral
administration.
[0172] In accordance with the present invention, compositions
provided may be administered to mammals. Administration may be in a
"therapeutically effective amount", this being sufficient to show
benefit to a patient. Such benefit may be at least amelioration of
at least one symptom. Thus "treatment of rheumatoid arthritis"
refers to amelioration of at least one symptom. The actual amount
administered, and rate and time-course of administration, will
depend on the nature and severity of what is being treated, the
particular mammal being treated, the clinical condition of the
individual patient, the cause of the disorder, the site of delivery
of the composition, the type of binding member, the method of
administration, the scheduling of administration and other factors
known to medical practitioners. Prescription of treatment, e.g.
decisions on dosage etc, is within the responsibility of general
practitioners and other medical doctors, and may depend on the
severity of the symptoms and/or progression of a disease being
treated. Appropriate doses of antibody are well known in the art
(Ledermann 1991 and Bagshawe 1991. Specific dosages indicated
herein, or in the Physician's Desk Reference (2003) as appropriate
for the type of medicament being administered, may be used. A
therapeutically effective amount or suitable dose of a binding
member for use in the invention can be determined by comparing its
in vitro activity and in vivo activity in an animal model. Methods
for extrapolation of effective dosages in mice and other test
animals to humans are known. The precise dose will depend upon a
number of factors, including whether the antibody is for diagnosis,
prevention or for treatment, the size and location of the area to
be treated, the precise nature of the antibody (e.g. whole
antibody, fragment or diabody), and the nature of any detectable
label or other molecule attached to the antibody. A typical
antibody dose will be in the range 100 .mu.g to 1 g for systemic
applications, and 1 .mu.g to 1 mg for topical applications. An
initial higher loading dose, followed by one or more lower doses,
may be administered. An antibody may be a whole antibody, e.g. the
IgG1 or IgG4 isotype. This is a dose for a single treatment of an
adult patient, which may be proportionally adjusted for children
and infants, and also adjusted for other antibody formats in
proportion to molecular weight. Treatments may be repeated at
daily, twice-weekly, weekly or monthly intervals, at the discretion
of the physician. Treatments may be every two to four weeks for
subcutaneous administration and every four to eight weeks for
intravenous administration. In some embodiments of the present
invention, treatment is periodic, and the period between
administrations is about two weeks or more, e.g. about three weeks
or more, about four weeks or more, or about once a month. In other
embodiments of the invention, treatment may be given before, and/or
after surgery, and may be administered or applied directly at the
anatomical site of surgical treatment.
[0173] Further aspects and embodiments of the invention will be
apparent to those skilled in the art given the present disclosure
including the following experimental exemplification.
[0174] Experimental
[0175] Results
[0176] Histochemical Analysis of Human Arthritic Specimens
[0177] Expression of fibronectin domains EDA and EDB as well as
tenascin-C domains A1 and C were investigated by
immunohistochemistry on human arthritic specimens using the F8,
L19, F16 and G11 antibodies respectively.
[0178] In FIG. 1 darker staining indicates expression of the
respective antigens (indicated with white arrows). The anti-EDA
antibody F8 led to the strongest staining, therefore all further
experiments were performed with this antibody.
[0179] Immunofluorescence experiments with the F8 antibody were
performed which showed a nice perivascular staining (visible as
white structures in FIG. 2).
[0180] The Human Monoclonal Antibody F8 Selectively Accumulates at
Sites of Arthritis in Mice
[0181] We studied the in vivo targeting performance of F8 in
mini-antibody format (SIP) (Borsi et al. 2002) in the CIA mouse
model (Courtney et al. 1980) using both fluorescence and
radioactivity for antibody detection. The SIP format consists of a
scFv antibody fragment linked to the CH4 domain of human IgE giving
rise to a homodimeric protein of 80 kDa in size.
[0182] Arthritic mice were injected with SIP(F8) labelled with the
near-infrared dye Alexa 750. Twenty-four hours after intravenous
injection, animals were imaged using an infrared fluorescence
imager (Birchler et al., 1999), revealing a strong and selective
antibody accumulation in the lesions present in the arthritic limb,
visible as white lighting paws, with some grade 2 swelling in front
paws of the mice.
[0183] Twenty-four hours after intravenous injection of SIP(F8)
radioactively labelled with .sup.125I, mice were sacrificed and
paws imaged by autoradiography (phosphorimaging). A preferential
accumulation of radioactivity was observed in the inflamed
extremities of mice injected with SIP(F8), visible as black
staining in autoradiography. One paw showed an arthritic score of 2
(swelling of the whole paw). Another paw was classified as grade 1
arthritis (swelling of single fingers).
[0184] Activity of Anti-ED-A Antibody-Interleukin-10 Fusion
[0185] Antibody molecule F8 in scFv format was conjugated within a
fusion protein with interleukin-10 (IL-10). Biological activity of
the fusion protein was compared with that of human IL-10 in an
assay determining ability to induce IL-4 dependent proliferation of
MC/9 cells (Thompson et al., 1991). The results are shown in FIG.
8(d).
[0186] Materials and Methods
[0187] Immunohistochemical Analysis on Human Arthritic
Specimens
[0188] Frozen sections of human arthritic specimens were fixed in
ice-cold acetone for 10', blocked with Fetal Bovine Serum for 30'
and stained for markers of neovasculature (Fibronectin ED-A and
ED-B, Tenascin-C domain A1 and C). The F8, L19, F16 and G11
antibodies were used as myc-tagged scFvs in a concentration of 10
ug/ml and incubated for 1 h. The primary antibodies were
coincubated with the anti-myc antibody 9E10 in concentration of 7
ug/ml. As tertiary detection antibody a rabbit anti-mouse IgG
antibody (Dako, Denmark) and APAAP Mouse Monoclonal (Dako, Denmark)
were used in concentrations of 5 and 50 ug/ml respectively for 1 h
each. Fast Red Tablets (Sigma, Switzerland) were used to develop
the staining incubating for 15'. Slides were counterstained with
hematoxylin for 2', washed with water, mounted with Glycergel
mounting medium (Dako, Denmark) and analyzed with a Axiovert 5100
TV microscope (Zeiss, Switzerland).
[0189] Immunofluorescence Analysis on Human Arthritic Specimens
[0190] Frozen sections of human arthritic specimens were fixed in
ice-cold acetone for 10', blocked with Fetal Bovine Serum for 30'
and stained for the EDA domain of fibronectin. The F8 antibody was
used as a myc-tagged scFv in a concentration of 10 ug/ml and
incubated for 1 h. The primary antibody was coincubated with the
anti-myc antibody 9E10 in a concentration of 7 ug/ml. As tertiary
detection antibody a fluorescent anti-mouse-Alexa 596 antibody
(Molecular Probes, Denmark) was used in a concentration of 10 ug/ml
for 1 h each. Slides were counterstained with Hoechst 33342,
mounted with Glycergel mounting medium (Dako, Denmark) and analyzed
with a AxioScop 2MOT+ microscope (Zeiss, Switzerland).
[0191] Animal Model
[0192] Male DBA/1 mice (8-12 weeks old) were immunized by
intradermal injection at the base of the tail of 200 .mu.g of
bovine type II collagen (MD Biosciences) emulsified with equal
volumes of Freund's complete adjuvant (MD Biosciences). 2 weeks
after the first immunization the procedure was repeated but
incomplete Freund's adjuvant (MD Biosciences) was used to emulsify
the collagen. Mice were inspected daily and each mouse that
exhibited erythema and/or paw swelling in 1 or more limbs was
assigned for imaging or treatment studies.
[0193] Arthritis was monitored using 2 disease indices (clinical
score and paw swelling). For the clinical score each limb was
graded daily in a not blinded fashion. (0=normal, 1=swelling of 1
or more fingers of the same limb, 2=swelling of the whole paw),
resulting in a maximum possible score of 8 per animal. Paw swelling
was assessed every second day using a calliper to measure the
thickness of each limb under isoflurane anaesthesia. The mean value
of all 4 paws was assigned as paw thickness to each animal.
[0194] Near-Infrared-Imaging of Arthritic Paws
[0195] The selective accumulation of SIP(F8) in arthritic mice was
tested by Near-Infrared-Imaging analysis as described by Birchler
et al. (1999). Briefly, purified SIP(F8) was labelled with Alexa750
(MolecularProbes, Leiden, The Netherlands) according to the
manufacturer's recommendations and 100 ug of labelled protein were
injected into the tail vein of arthritic mice. Mice were
anesthetized with Ketamin 80 mg/kg and Medetomidin 0.2 mg/kg and
imaged in a near-infrared-mouseimager 24 hr after injection
(Trachsel et al. 2007; Birchler et al. 1999).
[0196] Biodistribution Experiments
[0197] The in vivo targeting performance of SIP(F8) in arthritic
mice was evaluated by biodistribution analysis as described before
(Borsi et al. 2002; Tarli et al., 1999). Briefly, purified SIP(F8)
was radioiodinated and 10 ug of protein, corresponding to 11 uCi
.sup.125I, were injected into the tail vein of arthritic mice. Mice
were sacrificed 24 hr after injection and paws were exposed for 1
hour and read in a phosphorimager (Fujifilm BAS-5000) as described
before (Trachsel et al. 2007).
[0198] Antibodies
[0199] The isolation of the anti-ED-B antibody fragment scFv(L19)
has been previously described (Pini et al. 1998). The parent
anti-ED-A antibody was isolated from the ETH-2 library using
published procedures (Giovannoni, Nucleic. Acid Research, 2001,
29(5):E27). The affinity maturation of the parent anti-ED-A
antibody, yielding the high affinity anti-ED-A antibodies, is
described in the following section.
[0200] Affinity Maturation of the Parent Anti-ED-A Antibody
[0201] The parent anti-ED-A antibody (an ETH-2-derived antibody)
was used as template for the construction of an affinity maturation
library.
[0202] Sequence variability in the VH CDR1 (DP47 germline) and VL
CDR1 (DPK22 germline) of the library was introduced by PCR using
partially degenerate primers
5'-CTGGAGCCTGGCGGACCCAGCTCATMNNMNNMNNGCTAAAGGTGAAT CCAGA-3' (SEQ ID
NO: 17) for VH and 5'-CCAGGTTTCTGCTGGTACCAGGCTAA
MNNMNNMNNGCTAACACTCTGACTGGCCCTGC-3' (SEQ ID NO: 18) for VL (all
oligonucleotides were purchased from Operon Biotechnologies,
Cologne, Germany), in a process that generates random mutations at
positions 31, 32 and 33 of the VH CDR1 and at positions 31, 31a and
32 of the VL CDR1. VHVL combinations were assembled in scFv format
by PCR assembly using the primers LMB3long
(5'-CAGGAAACAGCTATGACCATGATTAC-3') (SEQ ID NO: 19) and fdseqlong
(5'-GACGTTAGTAAATGAATTTTCTGTATGAGG-3') (SEQ ID NO: 20), using
gel-purified VH and VL segments as templates. The assembled VH-VL
fragments were doubly digested with NcoI/NotI and cloned into
NcoI/NotI-digested pHEN1 phagemid vector (Hoogenboom et al., 1991).
The resulting ligation product was electroporated into
electrocompetent E. coli TG-1 cells according to (Viti et al.,
2000), giving rise to a library containing 1.5.times.10.sup.7
individual antibody clones, which was screened for antibodies which
bind ED-A with improved affinity.
[0203] Selection of Anti-ED-A Antibodies
[0204] The antibody library described above was screened for
antibodies which bound ED-A with a greater affinity than the parent
anti-ED-A antibody using BIAcore analysis. The antigen (11A12) used
in the BIAcore analysis contained the ED-A domain of human
fibronectin and has the following amino acid sequence (SEQ ID NO:
120):

[0205] The nucleotide sequence of antigen (11A12) (SEQ ID NO: 121)
is as follows:

[0206] The nucleotide sequence of the antigen was amplified by PCR
using primers containing BamHI and BglII restriction sites at the
5' and 3' respectively. The resulting PCR product and the vector
pQE12 (QIAGEN) were digested with BamHI and BglII restriction
endonuclease and subsequently ligated in a reaction containing a
ratio of insert to vector of 3:1. The resulting vector was
sequenced to check that the sequence was correct.
[0207] Antigen Preparation
[0208] A TG1 electrocompetent Preculture in 10 ml 2TY, Amp, 1%
Glucose was electroporated in the presence of 1 .mu.l of a DNA
miniprep of 11A12. The pre-culture was then diluted 1:100 (8 ml in
800 ml of 2TY, Amp, 0.1% Glucose) and grown to an OD600 of 0.4-0.6
and then induced with IPTG over night. The following day the cells
were spun down and the supernatant filtered (Millipore 0.22 .mu.m).
After centrifugation and clarification of the culture broth, 11A12
was purified using a Hitrap column on FPLC. The Ni/column was
regenerated as follows: the column was rinsed with 5 column volumes
(CV) H.sub.2O followed by application of 3CV 0.5 M EDTA/0.2 M Tris
pH 8 to wash the old Nickel out from the column. This was followed
by rinsing of the column with 5CV H2O. The column was then reloaded
with 2CV 100 mM NiSO4 followed by rinsing of the column with
several CVs H2O. The column was then equilibrated with 5CV lysis
buffer (20 mM imidazol/250 mM NaCl/PBS pH 7.4). The cell lysate was
filtered (Millipore 0.45 .mu.m) and loaded onto the column
(manually). The column was then put back on FPLC and the lysis
buffer left to flow until the UV signal was stable (constant),
about 3 CV. The elution program was then started: Gradient from 0%
to 100% of Elution Buffer (400 mM imidazol/250 mM NaCl/PBS pH 7.4)
in 5CV. The fractions containing the eluted antigen were pooled and
dialysed in PBS over night.
[0209] Expression and Purification of the Anti-ED-A Antibodies
[0210] The anti-ED-A antibodies were expressed and purified as
follows: A TG1 electrocompetent Preculture in 10 ml 2TY, Amp, 1%
Glucose was electroporated in the presence of 1 .mu.l of a DNA
miniprep of one of the anti-ED-A antibodies. The pre-culture was
then diluted 1:100 (8 ml in 800 ml of 2TY, Amp, 0.1% Glucose) and
grown to an OD600 of 0.4-0.6 and then induced with IPTG over night.
The following day the cells were spun down and the supernatant
filtered (Millipore 0.22 .mu.m). The scFv were purified on a
Protein A-Sepharose column and Triethylemmine was used to elute the
scFvs from the column. The fractions containing the eluted scFvs
were dialysed in PBS over night at 4.degree. C. The scFv fractions
were then put on a Superdex 75 column with PBS flowing at 0.5
ml/min and 0.25 ml fractions collected. The monomeric fractions
were used for BIAcore analysis.
[0211] BIAcore.TM. Analysis 1
[0212] The BIAcorem Chip was flushed overnight at a flow rate of 5
.mu.l/min with HBS-EP buffer BIACORE.TM., 0.01 M Hepes pH 7.4, 0.15
M NaCl, 3 mM EDTA, 0.005% surfactant P20 (same buffer used for the
assay). The antigen (11A12) was diluted to a concentration of 50
.mu.g/ml in acetate buffer (pH 4.0) and the COOH groups on the chip
were activated by injection of 50 .mu.l of a mix of N-Hydroxy
Succinimmide (NHS) and ethyl-N-(dimethylaminopropyl)-carbodiimide
(EDC). 40 .mu.l of the 11A12 antigen were injected onto the chip
and the residual free COOH groups were blocked with 30 .mu.l of
ethanolamine. After a 0.22 .mu.m filtration, 20 .mu.l of each
individual bacterial supernatant were injected onto the chip and
interaction with the antigen was monitored in real time.
[0213] BIAcore.TM. Analysis 2
[0214] The k.sub.on, k.sub.off and K.sub.D of the parent anti-ED-A
antibody and anti-ED-A antibodies B2, C5, D5, C8, F8, B7 and G9
were evaluated using
[0215] Surface Plasmon Resonance. The chip was equilibrated over
night with the same buffer used during the assay at a buffer flow
rate of 5 .mu.l/min. The whole coating procedure was performed at
this flow rate. The antigen 11A12 was diluted 1:25 with acetate
buffer pH 4.00 (provided by BIACORE.TM.) to a final concentration
of 20 .mu.g/ml. The NHS and EDC were then mixed and 50 .mu.l
injected to activate the COOH groups on the CM5 chip. This was
followed by injection of 40 .mu.l of the antigen (this lasts about
40''). Then 30 .mu.l of Ethanolammine were injected in order to
block the reactivity of eventual free COOH.
[0216] Each sample was assayed at a flow rate 20 .mu.l/min. 20
.mu.l of undiluted monomeric protein (as it comes out from the gel
filtration) was injected. The dissociation time was left to run for
about 200''. Then 10 .mu.l of HCl 10 mM was injected to regenerate
the chip. The injection of monomeric protein was repeated at
different dilutions, i.e. 1:2 dilution (in PBS) followed by
regeneration with HCl. This was followed by a third injection of
the protein, at a dilution of 1:4 followed again by regenartion
with HCl. The k.sub.on, k.sub.off and KD values for each anti-ED-A
antibody were evaluated using the BIAevaluation software.
[0217] Selection of Anti-ED-A Antibodies
[0218] BIAcore.TM. Analysis 1
[0219] The BIAcore.TM. analysis produced a graph for each anti-ED-A
antibody which was analysed to deduce the affinity of an antibody
for the antigen as follows: The x axis of each graph corresponds to
time and the y axis corresponds to Resonance Units (a measure which
indicates the binding affinity of the tested antibody for the
antigen coated onto the BIAcore.TM. chip). Each graph showed 3
peaks and 1 dip which correspond to changes of buffer and are
therefore irrelevant for the interpretation of the results.
[0220] The ascending part of each graph represents the association
phase. The steeper is the curve in this part of the graph, the
faster is the association of the antibody with the antigen. The
descending part of each graph represents the dissociation phase of
the antibody from the antigen. The flatter the curve in this part
of the graph is, the slower is the dissociation of the antibody
from the antigen.
[0221] Anti-ED-A antibodies H1, B2, C5, D5, E5, C8, F8, F1, B7, E8
and G9 all showed a flatter dissociation curve than the parent
anti-ED-A antibody from which they were derived, indicating that
they bind ED-A, and hence also A-FN, with a greater affinity than
the parent anti-ED-A antibody. The graphs for antibodies E5, F1, F8
and H1 showed the flattest dissociation curves of all the anti-ED-A
antibodies tested. The association curves of antibodies H1, C5, D5,
E5, C8, F8 and F1 were flatter than that observed for the parent
anti-ED-A antibody while the association curve observed for
antibodies B2, B7, E8 and G9 was as steep as the association curve
observed for the parent anti-ED-A antibody. However, as bacterial
supernatants of IPTG-induced E. coli TG-1 cells were used for the
BIAcore.TM. analysis of antibodies H1, B2, C5, D5, E5, C8, F8, F1,
B7, E8 and G9, the concentration of the tested antibody samples was
unknown but most probably lower than the concentration of the
parent anti-ED-A antibody sample used for comparison. Consequently,
the association curve of antibodies H1, B2, C5, D5, E5, C8, F8, F1,
B7, E8 and G9 may be artificially low due to the low concentration
of antibody in the samples used for the BIAcore.TM. analysis.
However, as concentration does not significantly affect the
dissociation of an antibody from its target antigen in BIAcorem
analysis, the flat dissociation curves observed for antibodies H1,
B2, C5, D5, E5, C8, F8, F1, B7, E8 and G9 show that these
antibodies bind ED-A with at least an equal, and probably a higher
affinity, than the parent anti-ED-A antibody.
[0222] BIAcore Analysis 2
[0223] The k.sub.on, k.sub.off and KD values for each anti-ED-A
antibody were evaluated using the BIAevaluation software. The
k.sub.on, k.sub.off and KD values of the parent anti-ED-A antibody
and anti-ED-A antibodies B2, C5, D5, C8, F8, B7 and G9 for antigen
11A12 are detailed in Table 2. Anti-ED-A antibodies B2, C5, D5, C8,
F8, B7 and G9 all have a better K.sub.D values for antigen 11A12
than the parent anti-ED-A antibody from which they were derived,
indicating that they bind ED-A, and hence also A-FN, with a greater
affinity than the parent anti-ED-A antibody.
[0224] Sequences
[0225] Anti-ED-A antibodies H1, B2, C5, D5, E5, C8, F8, F1, B7, E8
and G9 are all scFv antibodies and were sequenced using
conventional methods. The nucleotide sequence of the anti-ED-A

chain CDR1s listed in Table 1 for anti-ED-A antibody F8, and the
amino acid sequence of the linker in H1 is substituted with the
linker amino acid sequence GSSGG (SEQ ID NO: 28).
[0229] The amino acid sequence of the anti-ED-A antibody B2 VH

[0250] Cloning, Production and Characterization of F8-IL10
[0251] The human IL-10 gene was amplified by PCR using the
following primer sequences:
TABLE-US-00003 a backward antisense primer,
5'-TCGGGTAGTAGCTCTTCCGGCTCATCGTCCAGCGGCAGCCCAGGCCA GGGCACC-3'; and
a forward sense primer,
5'-TTTTCCTTTTGCGGCCGCtcattaGTTTCGTATCTTCATTGTCATGT A-3',
[0252] which appended part of a 15 amino acid linker (SSSSG).sub.3
at its N-terminal and stop codon and NotI restriction site at its
C-terminal.
[0253] DNA encoding the single-chain variable fragment (F8) was
amplified with a signal peptide using the following primer
pairs:
TABLE-US-00004 a backward antisense primer,
5'-CCCAAGCTTGTCGACCATGGGCTGGAGCC-3' and a forward sense primer,
5'-GAGCCGGAAGAGCTACTACCCGATGAGGAAGAGAATTOTTTGATTTC
CACCTTGGTCCCTTG-3'.
[0254] Using this strategy, a HindIII restriction site was inserted
at the N-terminal and a complementary part of the linker sequence
was inserted at the C-terminal.
[0255] The single-chain Fv and IL-10 fragments were then assembled
using PCR and cloned into the HindIII and NotI restriction sites of
the mammalian cell-expression vector pcDNA3.1(+).
[0256] CHO--S cells were stably transfected with the previously
described plasmids and selection was carried out in the presence of
G418 (0.5 g/l).
[0257] Clones of G418-resistant cells were screened for expression
of the fusion protein by ELISA using a recombinant EDA of human
fibronectin as antigens and Protein A for detection.
[0258] The fusion proteins were purified from the cell-culture
medium by affinity chromatography over Protein A columns.
[0259] The size of the fusion proteins was analysed in reducing and
nonreducing conditions on SDS-PAGE and in native conditions by FPLC
gel filtration on a Superdex S-200 exclusion column (Amersham
Pharmacia Biotech, Dubendorf, Switzerland).
[0260] Activity Assay
[0261] Biological activity of hIL10 was determined by its ability
to induce the IL-4 dependent proliferation of MC/9 cells
(Thompson-et al., 1991) using the colorimetric MTT dye-reduction
assay. 10.000 MC/9 (ATCC, Manassas, USA) cells/well in 200 .mu.l of
medium containing 5 .mu.g (0.05 Units) of murine IL4/ml
(eBiosciences) in a 96-well microtiter plate were treated for 48 hr
with varying amounts of human IL10. The hIL10 standard and the
F8-IL10 fusion protein were used at a maximum of 100 ng/ml IL10
equivalents and serially diluted. 10 .mu.l of 5 mg/ml MTT (Sigma)
was added and incubated for 3-5 hr. The cells were then
centrifuged, lysed with DMSO and read for absorbance at 570 nm.
