Definitions

  • the present invention relates to engineered antibody polypeptides. More particularly, the present invention provides antibody polypeptides comprising an antigen binding site, wherein the antigen binding site comprises a human variable domain having at least one New World Primate CDR. In particular the present invention relates to antibody polypeptides directed against TNF- ⁇ .
  • TNF- ⁇ Tumor Necrosis Factor- ⁇
  • RA rheumatoid arthritis
  • Crohn's disease Crohn's disease
  • ulcerative colitis and other bowel disorders
  • psoriasis toxic shock
  • graft versus host disease and multiple sclerosis.
  • the pro-inflammatory actions of TNF- ⁇ result in tissue injury, such as inducing procoagulant activity on vascular endothelial cells (Pober, et al., 1986, J.
  • TNF- ⁇ is synthesized as a 26 kD transmembrane precursor protein with an intracellular tail that is cleaved by a TNF- ⁇ -converting metalloproteinase enzyme and then secreted as a 17 kD soluble protein.
  • the active form consists of a homotrimer of the 17 kD monomers which interacts with two different cell surface receptors, p55 TNFR1 and p75 TNFR2.
  • p55 TNFR1 and p75 TNFR2 cell surface receptors
  • p75 receptor is implicated in triggering lymphocyte proliferation
  • the p55 receptor is implicated in TNF-mediated cytotoxicity, apoptosis, antiviral activity, fibroblast proliferation and NT- ⁇ B activation (see Locksley et al., 2001, Cell 104: 487-501).
  • the TNF receptors are members of a family of membrane proteins including the NGF receptor, Fas antigen, CD27, CD30, CD40, Ox40 and the receptor for the lymphotoxin ⁇ / ⁇ heterodimer. Binding of receptor by the homotrimer induces aggregation of receptors into small clusters of two or three molecules of either p55 or p75.
  • TNF- ⁇ is produced primarily by activated macrophages and T lymphocytes, but also by neutrophils, endothelial cells, keratinocytes and fibroblasts during acute inflammatory reactions. TNF- ⁇ is at the apex of the cascade of pro-inflammatory cytokines (Reviewed in Feldmann & Maini, 2001, Ann. Rev. Immunol.
  • This cytokine induces the expression or release of additional proinflammatory cytokines, particularly IL-1 und IL-6 (see, for example, Rutgeerts et al., 2004, Gastroenterology 126: 1593-1610). Inhibition of TNF- ⁇ inhibits the production of inflammatory cytokines including IL-1, IL-6, IL-8 and GM-CSF (Brennan et al., 1989, Lancet 2: 244-247). Because of its role in inflammation, TNF- ⁇ has emerged as an important inhibition target in efforts to reduce the symptoms of inflammatory disorders.
  • soluble TNF- ⁇ receptors and antibodies specific for TNF- ⁇ .
  • Commercial products approved for clinical use include, for example, the antibody products RemicadeTM (infliximab; Centocor, Malvern, Pa.; a chimeric monoclonal IgG antibody bearing human IgG1 constant and mouse variable regions), HumiraTM (adalimumab or D2E7; Abbott Laboratories, described in U.S. Pat. No. 6,090,382) and the soluble receptor product EnbrelTM (etancrcept, a soluble p75 TNFR2 Fc fusion protein; Immunex).
  • RemicadeTM infliximab
  • Centocor Centocor, Malvern, Pa.
  • HumiraTM adalimumab or D2E7
  • soluble receptor product EnbrelTM etancrcept, a soluble p75 TNFR2 Fc fusion protein
  • TNF- ⁇ is highly expressed in inflamed synovium, particularly at the cartilage-pannus junction (DiGiovine et al., 1988, Ann. Rheum. Dis. 47: 768-772; Firestein et al., 1990, J. Immunol. 144: 3347-3353; and Saxne et al., 1988, Arthritis Rheum. 31: 1041-1045).
  • TNF- ⁇ increases the levels of inflammatory cytokines IL-1, IL-6, IL-8 and GM-CSF
  • TNF- ⁇ can alone trigger joint inflammation and proliferation of fibroblast-like synoviocytes (Gitter et al., 1989, Immunology 66: 196-200), induce collagenase, thereby triggering cartilage destruction (Dayer et al., 1985, J. Exp. Med. 162: 2163-2168; Dayer et al., 1986, J. Clin. Invest.
  • TNF- ⁇ induces increased release of CD14+ monocytes by the bone marrow.
  • Such monocytes can infiltrate joints and amplify the inflammatory response via the RANK (Receptor Activator of NF- ⁇ B)-RANKL signaling pathway, giving rise to osteoclast formation during arthritic inflammation (reviewed in Anandarajah & Richlin, 2004, Curr. Opin. Rheumatol. 16: 338-343).
  • TNF- ⁇ is an acute phase protein which increases vascular permeability through its induction of IL-8, thereby recruiting macrophage and neutrophils to a site of infection. Once present, activated macrophages continue to produce TNF- ⁇ , thereby maintaining and amplifying the inflammatory response.
  • TNF- ⁇ Titration of TNF- ⁇ by the soluble receptor construct etanercept has proved effective for the treatment of RA, but not for treatment of Crohn's disease.
  • the antibody TNF- ⁇ antagonist infliximab is effective to treat both RA and Crohn's disease.
  • the mere neutralization of soluble TNF- ⁇ is not the only mechanism involved in anti-TNF-based therapeutic efficacy. Rather, the blockade of other pro-inflammatory signals or molecules that are induced by TNF- ⁇ also plays a role (Rutgeerts et al., supra).
  • the administration of infliximab apparently decreases the expression of adhesion molecules, resulting in a decreased infiltration of neutrophils to sites of inflammation.
  • infliximab therapy results in the disappearance of inflammatory cells from previously inflamed bowel mucosa in Crohn's disease.
  • This disappearance of activated T cells in the lamina propria is mediated by apoptosis of cells carrying membrane-bound TNF- ⁇ following activation of caspases 8,9 and then 3 in a Fas dependent manner (see Lugering et al., 2001, Gastroenterology 121: 1145-1157).
  • membrane- or receptor-bound TNF- ⁇ is an important target for anti-TNF- ⁇ therapeutic approaches.
  • infliximab binds to activated peripheral blood cells and lamina intestinal cells and induces apoptosis through activation of caspase 3 (sec Van den Brando et al., 2003, Gastroenterology 124: 1774-1785).
  • TNF- ⁇ Intracellularly, the binding of trimeric TNF- ⁇ to its receptor triggers a cascade of signaling events, including displacement of inhibitory molecules such as SODD (silencer of death domains) and binding of the adaptor factors FADD, TRADD, TRAF2, c-IAP, RAIDD and TRIP plus the kinase RIP1 and certain caspases (reviewed by Chen & Goeddel, 2002, Science 296: 1634-1635, and by Muzio & Saccani in :Methods in Molecular Medicine: Tumor Necrosis Factor, Methods and Protocols,” Corti and Ghezzi, eds. (Humana Press, New Jersey; 2004), pp. 81 -99).
  • SODD semiconductor of death domains
  • the assembled signalling complex can activate either a cell survival pathway, through NF- ⁇ B activation and subsequent downstream gene activation, or an apoptotic pathway through caspase activation. Similar extracellular downstream cytokine cascades and intracellular signal transduction pathways can be induced by TNF- ⁇ in other diseases. Thus, for other diseases or disorders in which the TNF- ⁇ molecule contributes to the pathology, inhibition of TNF- ⁇ presents an approach to treatment.
  • Angiogenesis plays an important role in the active proliferation of inflammatory synovial tissue. RA synovial tissue, which is highly vascularized, invades the periarticular cartilage and bone tissue and leads to joint destruction.
  • VEGF Vascular endothelial growth factor
  • VEGF is a secreted, heparin-binding, homodimeric glycoprotein existing in several alternate forms due to alternative splicing of its primly transcript (Leung et al., 1989, Science 246: 1306-1309).
  • VEGF is also known as vascular permeability factor (VPF) due to its ability to induce vascular leakage, a process important in inflammation.
  • VPF vascular permeability factor
  • VEGF expression in the joints increased upon induction of the disease, and the administration of anti-VEGF antisera blocked the development of arthritic disease and ameliorated established disease (Sone et al., 2001, Biochem. Biophys. Res. Comm. 281: 562-568; Lu et al., 2000, J. Immunol. 164: 5922-5927).
  • Antibodies are highly specific for their binding targets and although they are derived from nature's own defence mechanisms, antibodies face several challenges when applied to the treatment of disease inhuman patients.
  • Conventional antibodies are large multi-subunit protein molecules comprising at least four polypeptide chains.
  • human IgG has two heavy chains and two light chains that are disulfide bonded to form the functional antibody.
  • the size of a conventional IgG is about 150 kD. Because of their relatively large size, complete antibodies (e.g., IgG, IgA, IgM, etc.) are limited in their therapeutic usefulness due to problems in, for example, tissue penetration. Considerable efforts have focused on identifying and producing smaller antibody fragments that retain antigen binding function and solubility.
  • the heavy and light polypeptide chains of antibodies comprise variable (V) regions that directly participate in antigen interactions, and constant (C) regions that provide structural support and function in non-antigen-specific interactions with immune effectors.
  • the antigen binding domain of a conventional antibody is comprised of two separate domains: a heavy chain variable domain (VH) and a light chain variable domain (VL: which can be either V ⁇ or V ⁇ ).
  • VH heavy chain variable domain
  • VL light chain variable domain
  • the antigen binding site itself is formed by six polypeptide loops: three from the VH domain (H1, H2 and H3) and three from the VL domain (L1, L2 and L3). In vivo, a diverse primary repertoire of V genes that encode the VH and VL domains is produced by the combinatorial rearrangement of gene segments.
  • C regions include the light chain C regions (referred to as CL regions) and the heavy chain C regions (referred to as CH1, CH2 and CH3 regions).
  • CL regions the light chain C regions
  • CH1, CH2 and CH3 regions the heavy chain C regions
  • a number of smaller antigen binding fragments of naturally occurring antibodies have been identified following protease digestion. These include, for example, the “Fab fragment” (VL-CL-CH1-VH), “Fab′ fragment” (a Fab with the heavy chain hinge region) and “F(ab′)2 fragment” (a dimer of Fab′ fragments joined by the heavy chain hinge region).
  • Recombinant methods have been used to generate even smaller antigen-binding fragments, referred to as “single chain Fv” (variable fragment) or “scFv,” consisting of VL and VH joined by a synthetic peptide linker.
  • VHH domains VHH domains and retain the ability, when isolated as fragments of the VH chain, to bind antigen with high specificity
  • Antigen binding single VH domains have also been identified from, for example, a library of murine VH genes amplified from genomic DNA from the spleens of immunized mice and expressed in E. coli (Ward et al, 1989, Nature 341: 544-546). Ward et al. named the isolated single VH domains “dAbs,” for “domain antibodies”.
  • the term “dAb” will refer herein to a single immunoglobulin variable domain (VH, VHH or VL) polypeptide that specifically binds antigen.
  • a “dAb” binds antigen independently of other V domains; however, as the term is used herein, a “dAb” can be present in a homo- or heteromultimer with other VH or VL domains where the other domains are not required for antigen binding by the dAb, i.e., where the dAb binds antigen independently of the additional VH, VHH or VL domains.
  • Single immunoglobulin variable domains for example, VHH, are the smallest antigen-binding antibody unit known.
  • human antibodies are preferred, primarily because they are not as likely to provoke an immune response when administered to a patient. Isolated non-camelid VH domains tend to be relatively insoluble and are often poorly expressed.
  • WO 03/035694 (Muyldermans) reports that a Trp 103 Arg mutation improves the solubility of non-camelid VH domains, Davies & Riechmann, (1995, Biotechnology N.Y. 13: 475-479) also report production of a phage-displayed repertoire of camelized human VH domains and selection of clones that bind hapten with affinities in the range of 100-400 nM, but clones selected for binding to protein antigen had weaker affinities.
  • the antigen binding domain of an antibody comprises two separate regions: a heavy chain variable domain (VH) and a light chain variable domain (VL: which can be either V ⁇ or V ⁇ ).
  • the antigen binding site itself is formed by six polypeptide loops: three from VH domain (H1, H2 and H3) and three from VL domain (L1, L2 and L3).
  • VH domain H1, H2 and H3
  • VL domain L1, L2 and L3
  • a diverse primary repertoire of V genes that encode the VH and VL domains is produced by the combinatorial rearrangement of gene segments.
  • the VH gene is produced by the recombination of three gene segments, VH, D and JH. In humans, there are approximately 51 functional VH segments (Cook and Tomlinson, 1995, Immunol. Today, 16: 237), 25 functional D segments (Corbett et al., 1997 J. Mol.
  • VH segment encodes the region of the polypeptide chain which forms the first and second antigen binding loops of the VH domain (H1 and H2), whilst the VH, D and JH segments combine to form the third antigen binding loop of the VH domain (H3).
  • the VL gene is produced by the recombination of only two gene segments, VL and JL. In humans, there are approximately 40 functional V ⁇ segments (Schable and Zachau (1993) Biol. Chem.
  • the VL segment encodes the region of the polypeptide chain which forms the first and second antigen binding loops of the VL domain (L1 and L2), whilst the VL and JL segments combine to form the third antigen binding loop of the VL domain (L3).
  • Antibodies selected from this primary repertoire are believed to be sufficiently diverse to bind almost all antigens with at least moderate affinity.
  • High affinity antibodies are produced by “affinity maturation” of the rearranged genes, in which point mutations are generated and selected by the immune system on the basis of improved binding. Analysis of the structures and sequences of antibodies has shown that five of the six antigen binding loops (H1, H2, L1, L2, L3) possess a limited number of main-chain conformations or canonical structures (Chothia and Lesk, 1987, Mol. Biol., 196; 901-917; Chothia al., 1989, Nature, 342: 877-883).
  • the main-chain conformations are determined by (i) the length of the antigen binding loop, and (ii) particular residues, or types of residue, at certain key position in the antigen binding loop and the antibody framework. Analysis of the loop lengths and key residues has enabled us to predict the main-chain conformations of H1, H2, L1, L2 and L3 encoded by the majority of human antibody sequences (Chothia et al., 1992, J. Mol. Biol., 227: 799-817; Tomlinson et al., 1995, EMBO J., 14; 4628-4638; Williams et al., 1996, J. Mol. Biol., 264: 220-232).
  • H3 region is much more diverse in terms of sequence, length and structure (due to the use of D segments), it also forms a limited number of main-chain conformations for short loop lengths which depend on the length and the presence of particular residues, or types of residue, at key positions in the loop and the antibody framework (Martin et al., 1996, J. Mol. Biol, 263: 800-815; Shirai et al., 1996, FEBS Letters, 399: 1-8).
  • Bispecific antibodies comprising complementary pairs of VH and VL regions are known in the art. These bispecific antibodies must comprise two pairs of VH and VLs, each VH/VL pair binding to a single antigen or epitope.

  • each antibody species comprises two antigen-binding sites, each fashioned by a complementary pair of VH and VL domains. Each antibody is thereby able to bind to two different antigens or epitopes at the same time, with the binding to EACH antigen or epitope mediated by a VH and its complementary VL domain.
  • cross-reactive antibodies have been so described, usually where the two antigens are related in sequence and structure, such as hen egg white lysozyme and turkey lysozyme (McCafferty et al., WO 92/01047) or to free hapten and to hapten conjugated to carrier (Griffiths et al., 1994, EMBO J 13:14 3245-60).
  • WO 02/02773 (Abbott Laboratories) describes antibody molecules with “dual specificity”.
  • the antibody molecules referred to are antibodies raised or selected against multiple antigens, such that their specificity spans more than a single antigen.
  • Each complementary VH/VL pair in the antibodies of WO 02/02773 specifies a single binding specificity for two or more structurally related antigens; the VH and VL domains in such complementary pairs do not each possess a separate specificity.
  • the antibodies thus have a broad single specificity which encompasses two antigens, which are structurally related.
  • natural autoantibodies have been described that are polyreactive (Casali & Nolkins, 1989, Ann. Rev. Immunol. 7, 515-531), reacting with at least two (usually more) different antigens or epitopes mat are not structurally related.
  • Protein engineering methods have been suggested that may have a bearing on this.
  • a catalytic antibody could be created with a binding activity to a metal ion through one variable domain, and to a hapten (substrate) through contacts with the metal ion and a complementary variable domain (Barbae et al, 1993, Proc. Natl. Acad. Sci USA 90,6385-6389).
  • the binding and catalysis of the substrate is proposed to require the binding of the metal ion (second antigen).
  • the binding to the VH/VL pairing relates to a single but multi component antigen.
  • camel heavy chain single domains are unusual in that they are derived from natural camel antibodies which have no light chains, and indeed the heavy chain single domains are unable to associate with camel light chains to form complementary VH and VL pairs.
  • Single heavy chain variable domains have also been described, derived from natural antibodies which are normally associated with light chains (from monoclonal antibodies or from repertoires of domains; see EP-A-0368684). These heavy chain variable domains have been shown to interact specifically with one or more related antigens but have not been combined with other heavy or light chain variable domains to create a ligand with specificity for two or more different antigens. Furthermore, these single domains have been shown to have a very short in viva half-life. Therefore, such domains are of limited therapeutic value.
  • Human/mouse chimeric antibodies have been created in which antibody variable region sequences from the mouse genome are combined with antibody constant region sequences from the human genome.
  • the chimeric antibodies exhibit the binding characteristics of the parental mouse antibody, and the effector functions associated with the human constant region.
  • the antibodies are produced by expression in a host cell, including for example Chinese Hamster Ovary (CHO). NS0 myeloma cells, COS cells and SP2 cells.
  • Such chimeric antibodies have been used inhuman therapy, however antibodies to these chimeric antibodies have been produced by the human recipient. Such anti-chimeric antibodies are detrimental to continued therapy with chimeric antibodies.
  • human monoclonal antibodies are expected to be an improvement over mouse monoclonal antibodies for in vivo human therapy. From work done with antibodies from Old World primates (rhesus monkeys and chimpanzees) it has been postulated mat these non-human primate antibodies will be tolerated in humans because they are structurally similar to human antibodies (Ehrlich PH et al., 1988, Human and primate monoclonal antibodies for in vivo therapy. Clin Chem. 34:9 pg 1681-1688).
  • EP 0 605 442 discloses chimeric antibodies which bind human antigens. These antibodies comprise the whole variable region from an Old World monkey and the constant region of a human or chimpanzee antibody.
