Description

Antibody formulations in histidine-acetate buffer
This is a non-provisional application filed under 37CFR1.53(b), claiming priority from provisional application 60/620,413 filed on 10/20/2004, the contents of which are incorporated herein by reference.
Technical Field
The present invention relates to antibody formulations, including monoclonal antibodies formulated in histidine-acetate buffer, as well as formulations comprising antibodies that bind domain II of HER2 (e.g., Pertuzumab), and formulations comprising antibodies that bind DR5 (e.g., Apomab).
Background
In the last decade, advances in biotechnology have made it possible to produce a variety of proteins for pharmaceutical applications using recombinant DNA technology. The formulation of these proteins poses a particular problem because they are larger and more complex (i.e., have multiple functional groups in addition to a complex three-dimensional structure) than traditional organic and inorganic drugs. In order for a protein to retain biological activity, the formulation must maintain intact the conformational integrity of at least the core sequence of the protein's amino acids, while protecting the various functional groups of the protein from degradation. Degradation pathways for proteins may include chemical instability (i.e., any process involving modification of the protein by bond formation or cleavage, which results in a new chemical entity) or physical instability (i.e., a change in the higher order structure of the protein). Chemical instability can result from deamidation, racemization, hydrolysis, oxidation, beta elimination or disulfide exchange. Physical instability can result, for example, from denaturation, aggregation, precipitation or adsorption. The three most common protein degradation pathways are protein aggregation, deamidation and oxidation. Cleland et al Critical Reviews in therapeutics monitor Systems 10 (4): 307-377(1993).
Antibody formulations
Proteins for pharmaceutical applications include antibodies. An example of an antibody that may be used in therapy is an antibody that binds the HER2 antigen, such as Pertuzumab.

HER2 antibody
The HER family of receptor tyrosine kinases is an important regulator of cell growth, differentiation and survival. The receptor family includes four distinct members, including epidermal growth factor receptor (EGFR, ErbB1, or HER1), HER2(ErbB2 or p 185)neu) HER3(ErbB3) and HER4(ErbB4 or tyro 2).
EGFR encoded by the erbB1 gene is implicated in the etiology of human malignancies. In particular, increased EGFR expression has been observed in breast, bladder, lung, head, neck and stomach cancers as well as glioblastomas. Increased EGFR receptor expression is often associated with increased production of the EGFR ligand, transforming growth factor alpha (TGF- α), by the same tumor cells, which results in receptor activation through an autocrine stimulatory pathway. Baselga and Mendelsohn pharmac. ther.64: 127-154(1994). Monoclonal antibodies against EGFR or its ligands TGF-alpha and EGF have been evaluated as therapeutic agents in the treatment of these malignancies. See, e.g., Baselga and mendelsohn, supra; masui et al Cancer Research 44: 1002-1007 (1984); and Wu et al j.clin.invest.95: 1897-1905(1995).
Second member of the HER family, p185neuOriginally identified as the product of the transforming gene from neuroblastoma in chemically treated rats. The activated form of the neu proto-oncogene is produced by point mutations (valine to glutamic acid) in the transmembrane region of the encoded protein. Amplification of the neu human homolog is observed in breast and ovarian cancers and is associated with poor prognosis (Slamon et al, Science, 235: 177-182 (1987); Slamon et al, Science, 244: 707-712 (1989); and U.S. Pat. No. 4,968,603). To date, no point mutations similar to those in Neu protooncogenes have been reported for human tumors. Overexpression of HER2 (often but not uniformly due to gene amplification) has also been observed in other cancers, including cancers of the stomach, endometrium, salivary gland, lung, kidney, colon, thyroid, pancreas and bladder. See, King et al, Science, 229: 974 (1985); yokota et al, Lancet: 1: 765-; fukushige et al, Mol Cell biol, 6: 955- "958 (1986); guerin et al, Oncogene res, 3: 21-31 (1988); cohen et al, Oncogene, 4: 81-88 (1989); yonemura et al, Cancer res, 51: (1034 1991); borst et al, gynecol. oncol., 38: 364 (1990); weiner et al, Cancer res, 50: 421-; kern et al, Cancer res, 50: 5184 (1990); park et al, Cancer res, 49: 6605 (1989); zhau et al, mol. carcinog, 3: 254-; aasland et al br.j. cancer 57: 358-363 (1988); williams et al pathway 59: 46-52 (1991); and McCann et al, Cancer, 65: 88-92(1990). HER2 can be overexpressed in prostate Cancer (Gu et al Cancer Lett.99: 185-9 (1996); Ross et al hum.Pathol.28: 827-33 (1997); Ross et al Cancer 79: 2162-70 (1997); and Sadasivan et al J.Urol.150: 126-31 (1) 993))。
Anti-rat p185 has been describedneuAnd the human HER2 protein product. Drebin and colleagues cultivated anti-rat neu gene product, p185neuThe antibody of (1). See, e.g., Drebin et al, cell 41: 695-706 (1985); myers et al, meth.enzyme.198: 277-290 (1991); and WO 94/22478. Drebin et al Oncogene 2: 273-277(1988) report with p185neuThe mixture of antibodies reacting in two different regions brings about a synergistic antitumor effect on neu-transformed NIH-3T3 cells transplanted into nude mice. See also U.S. patent 5,824,311, published on month 10 and 20 of 1998.
Hudziak et al, mol.cell.biol.9 (3): 1165-1172(1989) describe the generation of a panel of HER2 antibodies, characterized by the human breast tumor cell line SK-BR-3. Relative cell proliferation of SK-BR-3 cells was determined by monolayer crystal violet staining after 72 hours exposure to the antibody. Using this assay, maximum inhibition was obtained with an antibody called 4D5 that inhibited cell proliferation by 56%. The other antibodies in this panel reduced cell proliferation to a lesser extent in this assay. It was further found that antibody 4D5 sensitizes breast tumor cell lines overexpressing HER2 to the cytotoxic effects of TNF-a. See also U.S. Pat. No. 5,677,171, published 10/14 in 1997. The HER2 antibody discussed in Hudziak et al is further characterized in the following literature.

Recombinant humanized forms of murine HER2 antibody 4D5 (huMAb4D5-8, rhuMAb HER2, Trastuzumab orU.S. Pat. No. 5,821,337) is clinically effective in patients with breast cancer that overexpresses HER2 who have previously received extensive anti-cancer therapy (Baselga et al, j.clin.oncol.14: 737-744(1996)). Trastuzumab received marketing approval from the food and drug administration at 25.9.1998 for the treatment of patients with metastatic breast cancer whose tumors overexpress HER2 protein.

Homology screening has identified two other HER receptor family members; HER3 (U.S. Pat. Nos. 5,183,884 and 5,480,968 and Kraus et al PNAS (USA) 86: 9193-. Both of these receptors exhibit enhanced expression in at least some breast cancer cell lines.
Various combinations of HER receptors are commonly found in cells, and heterodimerization is thought to enhance the diversity of cellular responses to a variety of HER ligands (ear et al Breast cancer research and Treatment 35: 115-132 (1995)). EGFR binds to six different ligands; epidermal Growth Factor (EGF), transforming Growth factor alpha (TGF-. alpha.), amphiregulin (ampheregulin), heparin-binding epidermal Growth factor (HB-EGF), beta cell protein (betacellulin) and epithelial regulatory protein (epiregulin) (Groenen et al Growth Factors 11: 235-257 (1994)). The heregulin protein family resulting from single gene selective cleavage are ligands of HER3 and HER 4. The heregulin family includes the alpha, beta and gamma heregulins (Holmes et al, Science, 256: 1205-1210 (1992); U.S. Pat. No. 5,641,869; and Schaefer et al Oncogene 15: 1385-1394 (1997)); neu Differentiation Factors (NDFs), Glial Growth Factors (GGFs); acetylcholine Receptor Inducing Activity (ARIA); and sensory and motor neuron derived factor (SMDF). For a review see Groenen et al Growth Factors 11: 235-257 (1994); lemke, g.molec. & cell.neurosci.7: 247-: 51-85(1995). Three additional HER ligands have recently been identified; neuregulin-2 (NRG-2) reported to bind HER3 or HER4 (Chang et al Nature 387509-; neuregulin-3 binding to HER4 (Zhang et al PNAS (USA)94 (18): 9562-7 (1997)); and neuregulin-4 which binds HER 4(Harari et al Oncogene 18: 2681-89 (1999)). HB-EGF, beta cell protein and epithelial regulatory protein also bind HER 4.
Although EGF and TGF α do not bind HER2, EGF stimulates EGFR and HER2 to form a heterodimer, which activates EGFR and leads to transphosphorylation of HER2 in the heterodimer. Dimerization and/or transphosphorylation appear to activate HER2 tyrosine kinase. See, Earp et al, supra. Similarly, when HER3 is co-expressed with HER2, an active signaling complex is formed and anti-HER 2 antibodies are able to disrupt this complex (Sliwkowski et al, J.biol.chem., 269 (20): 14661-14665 (1994)). Furthermore, HER3, when co-expressed with HER2, increased the affinity for regulatory proteins (HRG) to a higher affinity state. For the HER2-HER3 protein complex see also Levi et al, Journal of Neuroscience 15: 1329-; morrissey et al, proc.natl.acad.sci.usa 92: 1431-1435 (1995); and Lewis et al, cancer res, 56: 1457-1465(1996). HER4, like HER3, forms an active signaling complex with HER2 (Carraway and Cantley, Cell 78: 5-8 (1994)).
To target the HER signaling pathway, rhuMAb2C4(Pertuzumab, OMNITARG) was usedTM) Developed as humanized antibodies that inhibit dimerization of HER2 with other HER receptors, thereby inhibiting ligand-driven phosphorylation and activation, as well as downstream activation of the RAS and AKT pathways. In a phase I trial of Pertuzumab as a single agent for treating solid tumors, three subjects with advanced ovarian cancer were treated with Pertuzumab. One patient had a sustained partial response, while the other subjects had stable disease for 15 weeks, Agus et al Proc Am Soc Clin Oncol 22: 192, Abstract 771 (2003).
DR5 antibody
Various ligands and receptors belonging to the Tumor Necrosis Factor (TNF) superfamily have been identified in the art. These ligands include tumor necrosis factor-alpha ("TNF-alpha"), tumor necrosis factor-beta ("TNF-beta" or "lymphotoxin-alpha"), lymphotoxin-beta ("LT-beta"), CD30 ligand, CD27 ligand, CD40 ligand, OX-40 ligand, 4-1BB ligand, LIGHT, Apo-1 ligand (also known as Fas ligand or CD95 ligand), Apo-2 ligand (also known as Apo2L or TRAIL), Apo-3 ligand (also known as TWEAK), APRIL, OPG ligand (also known as RANK ligand, ODF, or TRANCE), and TALL-1 (also known as BlyS, BAFF, or THANK) (see, for example, Ashkenazi, Nature Review, 2: 420-Bufonic 430 (2002); Ashkenazi and Xit, Science, 281: Ashkenazi 1305 (1998); Dihkenazi and Curxit, Currin, Op. 255, cell 11, cell 1308, 11, cell, 11, 75, 2000, 11, 75, 2000, 7, 3, 7, K, and D, D, 7: 750-; locksley et al, Cell, 104: 487 501 (2001); gruss and Dower, Blood, 85: 3378-3404 (1995); schmid et al, proc.natl.acad.sci., 83: 1881 (1986); dealtry et al, eur.j.immunol., 17: 689 (1987); pitti et al, j.biol.chem., 271: 12687-; wiley et al, Immunity, 3: 673-682 (1995); browning et al, Cell, 72: 847-; armitage et al Nature, 357: 80-82(1992), WO 97/01633 published 1997 on 16.1; WO 97/25428 published on 17.7.1997; marsters et al, curr. biol., 8: 525-528 (1998); chicaporthe et al, biol. chem., 272: 32401-32410 (1997); hahne et al, j.exp.med., 188: 1185-1190 (1998); WO98/28426, published on 2.7.1998; WO98/46751, published on 22/10/1998; WO/98/18921 published on 7/5/1998; moore et al, Science, 285: 260-263 (1999); shu et al, j.leukcyte biol., 65: 680 (1999); schneider et al, j.exp.med., 189: 1747 — 1756 (1999); mukhopadhyay et al, j.biol.chem., 274: 15978-15981(1999)).
The induction of various cellular responses mediated by these TNF family ligands is generally initiated by their binding to specific cellular receptors. Some, but not all TNF family ligands bind through cell surface "death receptors" and induce various biological activities to activate caspases, or enzymes that execute cell death or apoptosis pathways (Salvesen et al, cell, 91: 443-446 (1997)). Members of the TNF receptor superfamily identified to date include TNFR1, TNFR2, TACI, GITR, CD27, OX-40, CD30, CD40, HVEM, Fas (also referred to as Apo-1 or CD95), DR4 (also referred to as TRAIL-R1), DR5 (also referred to as Apo-2 or TRAIL-R2), DcR1, DcR2, Osteoprotegerin (OPG), RANK and Apo-3 (also referred to as DR3 or TRAMP), and the like.
Most of these TNF receptor family members share a structure typical of cell surface receptors, including extracellular, transmembrane and intracellular domains, while other members are found naturally as soluble proteins lacking transmembrane and intracellular domains. The extracellular portion of typical TNFRs contains an initiation NH sequence2Repetitive amino acid sequence patterns of terminal multiple Cysteine Rich Domains (CRDs).
Ligands known as Apo-2L or TRAIL were identified a few years ago as members of the TNF family of cytokines (see, e.g., Wiley et al, Immunity, 3: 673-682 (1995); Pitti et al, J.biol.chem., 271: 12697-12690 (1996); WO 97/01633; WO 97/25428; U.S. Pat. No. 5,763,223, 6/9/1998; U.S. Pat. No. 6,284,236, 9/4/2001). Full-length native sequence human Apo2L/TRAIL polypeptide is a 281 amino acid long type II transmembrane protein. Some cells are capable of producing the polypeptide in its native soluble form by enzymatically cleaving the extracellular domain of the polypeptide (Mariani et al, J.cell.biol., 137: 221-229 (1997)). Soluble forms of Apo2L/TRAIL crystallization studies have shown a homotrimeric structure similar to that of TNF and other related proteins (Hymowitz et al, mol. cell, 4: 563-571 (1999); Cha et al, Immunity, 11: 253-261 (1999); Mongkolsapaya et al, Nature Structural Biology, 6: 1048 (1999); Hymowitz et al, Biochemistry, 39: 633-644 (2000)). However, Apo2L/TRAIL, unlike other TNF family members, was found to have unique structural features in which three cysteine residues (at position 230 of each subunit of the homotrimer) are coordinated together with a zinc atom, and zinc binding is important for trimer stability and biological activity (Hymowitz et al, supra; Bodmer et al, J.biol.chem., 275: 20632-one 20637 (2000)).
Apo2L/TRAIL has been reported in the literature to play a role in immune system regulation, including in autoimmune diseases such as rheumatoid arthritis (see, e.g., Thomas et al, J.Immunol., 161: 2195 & 2200 (1998); Johnsen et al, cytokine, 11: 664 & 672 (1999); Griffith et al, J.exp.Med., 189: 1343 & 1353 (1999); Song et al, J.exp.Med., 191: 1095 & 1103 (2000)).
Soluble forms of Apo2L/TRAIL have been reported to induce apoptosis in a number of Cancer cells, including tumors of the colon, lung, breast, prostate, bladder, kidney, ovary and brain, as well as melanoma, leukemia, and multiple myeloma (see, e.g., Wiley et al, supra; Pitti et al, supra; U.S. Pat. No. 6,030,945, 2/29/2000; U.S. Pat. No. 6,746,668, Rieger et al, FEBS Letters, 427: 124-. In vivo studies in murine tumor models further suggest that Apo2L/TRAIL, alone or in combination with chemotherapy or radiation therapy, is capable of exerting a substantial anti-tumor effect (see, e.g., Ashkenazi et al, supra; Walzcak et al, supra; Gliniak et al, Cancer Res., 59: 6153-6158 (1999); Chinnaiyan et al, supra; Roth et al, biochem. Biophys. Res. Comm., 265: 1999 (1999); PCT application US/00/15512; PCT application US/01/23691). In contrast to many types of cancer cells, most normal human cell types appear to be resistant to apoptosis induction by some recombinant form of Apo2L/TRAIL (Ashkenazi et al, supra; Walzcak et al, supra). Jo et al reported that polyhistidine-labeled soluble forms of Apo2L/TRAIL induce apoptosis in vitro in normally isolated human hepatocytes but not in non-human hepatocytes (Jo et al, Nature Med., 6: 564-567 (2000); see also, Nagata, Nature Med., 6: 502-503 (2000)). It is believed that the biochemical properties and biological activities of certain recombinant Apo2L/TRAIL preparations for diseased and normal cells may vary depending on, for example, the presence or absence of marker molecules, zinc content, and percent trimer content (see Lawrence et al, Nature Med., Letter to the Editor, 7: 383-385 (2001); Qin et al, Nature Med., Letter to the Editor, 7: 385-.
Apo2L/TRAIL has been found to bind to at least five different receptors. At least two of the Apo2L/TRAIL binding receptors contain a functional cytoplasmic death domain. One such receptor is termed "DR 4" (and/or as TR4 or TRAIL-R1) (Pan et al, Science, 276: 111-113 (1997); see also WO98/32856, published on 30.7.1998, WO99/37684, published on 29.7.1999, WO 00/73349, published on 7.12.7.2000, US6,433,147, published on 13.8.2002, US6,461,823, published on 8.10.8.2002, and US6,342,383, published on 29.1.2002).
Another such receptor for Apo2L/TRAIL is designated DR5 (or it is also designated Apo-2; TRAIL-R or TRAIL-R2, TR6, Tango-63, hAPO8, TRICK2 or KILLER) (see, for example, Sheridan et al, Science, 277: 818-821(1997), Pan et al, Science, 277: 815-818(1997), WO98/51793, 11.19.1998; WO98/41629, 24.1998; Scandaton et al, Curr.biol., 7: 693-696 (1997); Walczak et al, EMBO J., 16: 5386-5387(1997), Wu et al, Nature Genetics, 17: 141-143(1997), WO 98/98, 35, 1998: 35: 5386-5387(1997), WO 1998; WO 35: 1998; WO 2/35: 1998; 1998: 4610, 1998; WO 2/35: 1998; 1999, WO 2/11; 1999, 1998, WO 2, 1998, 35, 1999 2002/0072091, respectively; US 2002/0098550 published on 12/7/2001; US6,313,269 published at 12/6/2001; US2001/0010924, published on 8/2/2001; US 2003/01255540 published on 7/3/2003; US 2002/0160446, published at 31/10/2002, US2002/004878, published at 25/4/2002; US6,342,369 published in month 2 2002; US6,569,642 published on 27 th 5 th 2003, US6,072,047 published on 6 th 2000, US6,642,358 published on 4 th 11 th 2003; IS 6,743,625 published on 6/1/2004). Like DR4, DR5 is reported to contain a cytoplasmic death domain and to be capable of signaling apoptosis upon ligand binding (or via binding to a molecule, such as an agonist antibody, that mimics the activity of the ligand). The crystal structure of the complex formed between Apo-2L/TRAIL and DR5 is described in Hymowitz et al, Molecular Cell, 4: 563 and 571 (1999).
After ligand binding, both DR4 and DR5 are able to promote apoptosis by the death domain-containing linker molecule called FADD/Mort1, independently by recruiting and activating the apoptosis-initiating factor caspase-8 (Kischkel et al, Immunity, 12: 611-620 (2000); Sprick et al, Immunity, 12: 599-609 (2000); Bodmer et al, Nature Cell biol., 2: 241-243 (2000)).
Apo2L/TRAIL is reported to also bind to those receptors designated DcR1, DcR2 and OPG, which are believed to act as inhibitors, but not a signaling agent (see, e.g., DcR1 (also known as TRID, LIT or TRAIL-R3) (Pan et al, Science, 276: 111-113 (1997); sheridan et al, Science 277: 818-821 (1997); McFarlane et al, J.biol.chem., 272: 25417-; schneider et al, FEBS Letters, 416: 329- > 334 (1997); Degli-Esposti et al, J.Exp.Med., 186: 1165-1170 (1997); and Mongkolsapaya et al, J.Immunol., 160: 3-6 (1998); DcR2 (also known as TRUNDD or TRAIL-R4) (Marster et al, Curr. biol., 7: 1003-1006 (1997); pan et al, FEBS Letters, 424: 41-45 (1998); Degli-Esposti et al, Immunity, 7: 813-820(1997)), in contrast to DR4 and DR5, DcR1 and DcR2 receptors do not signal apoptosis.
Certain antibodies that bind DR4 and/or DR5 receptors have been reported in the literature. For example, anti-DR 4 antibodies directed against the DR4 receptor and having agonistic or apoptotic activity in certain mammalian cells are disclosed in, for example, WO 99/37684 at 29.7/1999; WO 00/73349, published on 12/7/2000; described in WO 03/066661 published on 8/14/2003. See also, for example, Griffith et al, j.immunol., 162: 2597-2605 (1999); chuntharapaai et al, j.immunol., 166: 4891 vs 4898 (2001); WO 02/097033, published on 12/2/2002; WO 03/042367, published on 5/22/2003; WO 03/038043, published on 8/5/2003; WO03/037913, 5/8/2003. Certain anti-DR 5 antibodies are likewise described, see, e.g., WO 98/51793, published at 11/8 of 1998; griffith et al, j.immunol., 162: 2597-2605 (1999); ichikawa et al, Nature med., 7: 954-960 (2001); hylander et al, "An Antibodyto DR5 (TRAIL-receiver 2) supresses the Growth of parent derived restricted specific turbines Growth in SCID Mouse", Abstract, 2d International Congress on Monoclonal antibodies in cancer, aug.29-Sept.1, 2002, Banff, Alberta, Canada; WO 03/038043, published on 8/5/2003; WO03/037913 published on 8/5/2003. In addition, certain antibodies have been described that have cross-reactivity to both DR4 and DR5 receptors (see, e.g., U.S. patent 6,252,050, 6/26, 2001).

Detailed description of the preferred embodiments
I. Definition of
The term "pharmaceutical formulation" refers to a preparation which is in a form which allows the biological activity of the active ingredient to be effective, and which does not contain other components which are unacceptably toxic to the subject to which the formulation is to be administered. These formulations are sterile.
"sterile" preparations are sterilized (ascitic) or free of all living microorganisms and their spores.
As used herein, a "frozen" formulation is a formulation at a temperature below 0 ℃. Generally, a frozen formulation is not lyophilized, nor is it lyophilized before or after. Preferably, the frozen preparation comprises a frozen drug substance (in a stainless steel jar) or a frozen drug product (in the final vial configuration) for preservation.
A "stable" formulation is one in which the protein substantially retains its physical and/or chemical stability and/or biological activity after storage. Preferably, the formulation substantially retains its physical and chemical stability, as well as its biological activity, after storage. The shelf life is generally selected based on the desired shelf life of the formulation. Various analytical techniques for measuring Protein stability are known in the art and are described, for example, in Peptide and Protein Drug Delivery, 247-: a review is made in 29-90 (1993). Stability can be measured at a selected temperature for a selected time. Preferably, the formulation is stable at about 40 ℃ for at least about 2-4 weeks, and/or at about 5 ℃ and/or 15 ℃ for at least 3 months, and/or at about-20 ℃ for at least 3 months or at least 1 year. In addition, the formulation is preferably stable after freezing (to, e.g., -70 ℃) and thawing of the formulation, e.g., after 1, 2 or 3 cycles of freeze-thawing. Stability can be assessed qualitatively and/or quantitatively in a number of different ways, including assessing aggregate formation (e.g., using size exclusion chromatography, by measuring turbidity, and/or by visual inspection); (ii) assessing charge heterogeneity by using cation exchange chromatography or capillary partition electrophoresis; amino-terminal or carboxy-terminal sequence analysis; mass spectrometry analysis; SDS-PAGE analysis to compare reduced and intact antibodies; peptide mapping (e.g., trypsin or LYS-C) analysis; assessing the biological activity or antigen binding function of the antibody; and so on. Instability may include any one or more of the following: aggregation, deamidation (e.g., Asn deamidation), oxidation (e.g., Met oxidation), isomerization (e.g., Asp isomerization), cleavage/hydrolysis/fragmentation (e.g., hinge region fragmentation), succinimide formation, unpaired cysteines, N-terminal extensions, C-terminal processing, glycosylation differences, and the like.
A "deamidated" monoclonal antibody herein is one in which one or more asparagine residues thereof have been derivatized, for example, to aspartic acid or iso-aspartic acid.
An antibody that is "susceptible to deamidation" is one that includes one or more residues that are found to be susceptible to deamidation.
An antibody that is "susceptible to aggregation" is one that has been found to aggregate with other antibody molecules, particularly after freezing and/or agitation.
An antibody that is "easily fragmented" is one that has been found to be cleaved into two or more fragments, for example at its hinge region.
"reducing deamidation, aggregation, or fragmentation" is intended to prevent or reduce the amount of deamidation, aggregation, or fragmentation relative to monoclonal antibodies formulated at a different pH or in a different buffer.
As used herein, "biological activity" of a monoclonal antibody refers to the ability of the antibody to bind to an antigen and result in a measurable biological response, which can be measured in vitro or in vivo. Such activity may be antagonistic (e.g. when the antibody is a HER2 antibody) or agonistic (e.g. when the antibody binds DR 5). For Pertuzumab, in one embodiment, biological activity refers to the ability of the formulated antibody to inhibit proliferation of the human breast cancer cell line MDA-MB-175-VII. When the antibody is Apomab, biological activity can refer, for example, to the ability of the formulated antibody to kill colon cancer, Colo205 cells.
By "isotonic" is meant that the formulation of interest has substantially the same osmotic pressure as human blood. An isotonic formulation will generally have an osmotic pressure of from about 250 to 350 mOsm. Isotonicity can be measured using, for example, a vapor pressure or freezing type osmometer.
As used herein, "buffer" refers to a buffered solution that is resistant to pH changes by the action of its acid-base conjugated components. The buffer of the invention preferably has a pH of from about 5.0 to about 7.0, preferably from about 5.5 to about 6.5, for example from about 5.8 to about 6.2, most preferably a pH of about 6.0. Examples of buffers that will control the pH in this range include acetate, succinate, gluconate, histidine, citrate, glycylglycine and other organic acid buffers. The preferred buffer herein is histidine buffer.
A "histidine buffer" is a buffer that includes histidine ions. Examples of histidine buffers include histidine chloride, histidine acetate, histidine phosphate, histidine sulfate. The preferred histidine buffer identified in the examples herein was found to be histidine acetate. In a preferred embodiment, the histidine acetate buffer is prepared by titration of L-histidine (free base, solid) with acetic acid (liquid). Preferably, the histidine buffer or histidine-acetate buffer is at pH5.5-6.5, preferably at pH 5.8-6.2.

The preferred surfactant herein is polysorbate 20.
A "HER receptor" is a receptor protein tyrosine kinase that belongs to the HER receptor family, including the EGFR, HER2, HER3, and HER4 receptors, as well as other members of this family identified in the future.

Examples of heregulins include heregulin-alpha, heregulin-beta 1, heregulin-beta 2 and heregulin-beta 3(Holmes et al, Science, 256: 1205-1210 (1992); and U.S. Pat. No. 5,641,869); neu Differentiation Factor (NDF) (Peles et al cell 69: 205-216 (1992)); acetylcholine Receptor Inducing Activity (ARIA) (Falls et al Cell 72: 801. cona. 815 (1993));]glial Growth Factors (GGFs) (Marchionni et al, Nature, 362: 312-318 (1993)); sensory and motor neuron derived factor (SMDF) (Ho et al J.biol.chem.270: 14523-; gamma-heregulin (Schaefer et al Oncogene 15: 1385-1394 (1997)). The term includes biologically active fragments and/or amino acid sequence variants of native sequence HRG polypeptides, such as EGF-like domain fragments thereof (e.g., HRG β 1)177-244)。
As used herein, a "HER dimer" is a non-covalently bound dimer comprising at least two different HER receptors. Such complexes may form when cells expressing two or more HER receptors are exposed to a HER ligand and may be isolated by immunoprecipitation and analyzed by SDS-PAGE, as described, for example, by Sliwkowski et al, j.biol.chem., 269 (20): 14661-. Examples of such HER dimers include EGFR-HER2, HER2-HER3, and HER3-HER4 heterodimers. In addition, the HER dimer may comprise two or more HER2 receptors that bind different HER receptors, such as HER3, HER4, or EGFR. Other proteins, such as cytokine receptor subunits (e.g., gp130) can be associated with the dimer.
A "heterodimer binding site" on HER2 refers to a region in the extracellular domain of HER2 that contacts, or contacts, a region in the extracellular domain of EGFR, HER3, or HER4 after dimer formation. This region is found in domain II of HER 2. Franklin et al Cancer Cell 5: 317-328(2004).
"HER activation" or "HER 2 activation" refers to the activation, or phosphorylation, of any one or more HER receptors, or HER2 receptors. In general, HER activation results in signal transduction (e.g., that initiated by the intracellular kinase domain of the HER receptor, which phosphorylates tyrosine residues in the HER receptor or substrate polypeptide). HER activation can be mediated by binding of a HER ligand to a HER dimer comprising the HER receptor of interest. HER ligand binding to the HER dimer may activate the kinase domain of one or more HER receptors in the dimer and thereby result in phosphorylation of tyrosine residues in one or more HER receptors, and/or phosphorylation of tyrosine residues in other substrate polypeptides, such as Akt or MAPK intracellular kinases.
The term "antibody" as used herein in the broadest sense specifically includes full length monoclonal antibodies, polyclonal antibodies, multispecific antibodies (e.g., bispecific antibodies) formed from at least two full length antibodies, and antibody fragments so long as they exhibit the desired biological activity.
The term "monoclonal antibody" as used herein refers to an antibody obtained from a substantially homogeneous population of antibodies, i.e., the individual antibodies comprising the population are identical and/or bind the same epitope, except for variants that may occur during the production of the monoclonal antibody, which variants are typically present in small amounts. In contrast to polyclonal antibody preparations, which typically include different antibodies directed against different determinants (epitopes), each monoclonal antibody is directed against a single determinant on the antigen. In addition to their specificity, they are also advantageous in that they are not contaminated with other immunoglobulins. The modifier "monoclonal" refers to the character of the antibody as being obtained from a substantially homogeneous population of antibodies, and is not to be construed as limiting the production of the antibody by any particular method. For example, monoclonal antibodies for use in accordance with the invention may be produced by a method described by Kohler et al, nature, 256: 495(1975) or can be prepared by recombinant DNA methods (e.g., U.S. Pat. No. 4,816,567). "monoclonal antibodies" can also be identified using Clackson et al, Nature, 352: 624-: 581-597(1991) from phage antibody libraries.
Monoclonal antibodies herein specifically include "chimeric" antibodies (immunoglobulins) in which a portion of the heavy and/or light chain is identical or homologous to the corresponding sequence of an antibody derived from a particular species or belonging to a particular antibody class or subclass, while the remainder of the chain is identical or homologous to the corresponding sequence of an antibody derived from another species or belonging to another antibody class or subclass, provided that they exhibit the desired biological activity (see U.S. Pat. No. 4,816,567; Morrison et al, proceedings of the national academy of sciences USA 81: 6851-6855 (1984)). Chimeric antibodies of interest herein include "primatized" antibodies comprising antigen binding sequences derived from non-human primate variable domains (e.g., Old World Monkey, ape, etc.) and human constant region sequences.
Antibody fragments "include a portion of a full-length antibody, preferably including the antigen-binding or variable regions thereof. Examples of antibody fragments include Fab, Fab ', F (ab') 2, and Fv fragments; a bivalent antibody; a linearized antibody; a single chain antibody molecule; and multispecific antibodies composed of antibody fragments.
A "full-length antibody" is an antibody comprising an antigen-binding variable region and a light chain constant domain (C) L) And heavy chain constant domains s, CH1,CH2 and CH3. The constant domain may be a native sequence constant domain (e.g., a human native sequence constant domain) or an amino acid sequence variant thereof. Preferably, the full length antibody has one or more effector functions.
The term "major species antibody" herein refers to an antibody structure in a composition that is the predominant antibody molecule in the composition in terms of quantity. In one embodiment, the main species antibody is a HER2 antibody, such as an antibody that binds to domain II of HER2, an antibody that inhibits HER dimerization more effectively than Trastuzumab, and/or an antibody that binds to the heterodimeric binding site of HER 2. A preferred embodiment of the main component HER2 antibody herein is one which comprises the variable light and variable heavy amino acid sequences of SEQ ID nos.3 and 4, most preferably the light and heavy chain amino acid sequences of SEQ ID nos.15 and 16 (Pertuzumab).
An "amino acid sequence variant" antibody herein is an antibody having an amino acid sequence that differs from that of the main species of antibody. Generally, amino acid sequence variants will have at least about 70% homology with the main species of antibody, preferably they will have at least about 80%, more preferably at least about 90% homology with the main species of antibody. Amino acid sequence variants have substitutions, deletions, and/or additions at certain positions within or adjacent to the amino acid sequence of the main species of antibody. Examples of amino acid sequence variants herein include acidic variants (e.g., deamidated antibody variants), basic variants, antibodies having amino-terminal directed extensions (e.g., VHS-) on one or both of their light chains, antibodies having C-terminal lysine residues on one or both of their heavy chains, and the like, and include combinations of heavy and/or light chain amino acid sequence variations. A particular antibody variant of interest herein is an antibody comprising an amino-terminal directed extension on one or both of its light chains, optionally further comprising other amino acid sequences and/or glycosylation differences relative to the main species antibody.
A "therapeutic monoclonal antibody" is an antibody used to treat a human subject. Therapeutic monoclonal antibodies disclosed herein include: HER2 antibody for use in cancer and various non-malignant diseases or disorders; a CD20 or BR3 antibody for use in the treatment of a B cell malignancy, an autoimmune disease, transplant rejection, or suppression of an immune response against a foreign antigen; IgE antibodies for use in the treatment of IgE-mediated disorders; a DR5 or VEGF antibody for use in the treatment of cancer.
A "glycosylation variant" antibody herein is an antibody having one or more sugar moieties attached thereto that is different from the one or more sugar moieties attached to the main species of antibody. Examples of glycosylation variants herein include antibodies having the G1 or G2 oligosaccharide structure, but not the G0 oligosaccharide structure, attached to their Fc region, antibodies having one or two sugar moieties attached to one or two light chains thereof, antibodies having no sugar attached to one or two heavy chains of the antibody, and the like, as well as combinations of glycosylation variations.
When the antibody has an Fc region, an oligosaccharide structure such as that shown in figure 16 may be attached to one or both heavy chains of the antibody, for example at residue 299 (298, Eu numbering of residues). G0 is the predominant oligosaccharide structure for Pertuzumab, with lesser amounts of other oligosaccharide structures such as G0-F, G-1, Man5, Man6, G1-1, G1(1-6), G1(1-3) and G2 being found in Pertuzumab compositions.
Unless otherwise specified, "G1 oligosaccharide structures" herein include G-1, G1-1, G1(1-6) and G1(1-3) structures.
Herein, "amino-terminal leader extension" refers to one or more amino acid residues of an amino-terminal leader sequence, which are present at the amino terminus of any one or more heavy or light chains of an antibody. Exemplary amino-terminal guide extensions comprise or consist of three amino acid residues, VHS, present in one or both light chains of an antibody variant.
"homology" is defined as the percentage of amino acid sequence variant residues that are identical after aligning the sequences and introducing gaps, if necessary, to achieve the maximum percent homology. Methods and computer programs for performing the alignment are well known in the art. One such computer program is "Align 2" which was archived in its user file at the U.S. copyright office, washington, DC20559, 12/10, 1991.
Antibody "effector functions" refer to those biological activities attributable to the Fc region of an antibody (either the native sequence Fc region or the amino acid sequence variant Fc region). Examples of "effector functions" include C1q binding; complement-dependent cytotoxicity; fc receptor binding; antibody-dependent cell-mediated cytotoxicity (ADCC); phagocytosis; downregulation of cell surface receptors (e.g., B cell receptor; BCR), and the like.
Full-length antibodies can be assigned to different "classes" based on the amino acid sequence of their heavy chain constant domains. There are five major full-length antibody classes: IgA, IgD, IgE, IgG, and IgM, several of which can be further divided into "subclasses" (isotypes), e.g., IgG1, IgG2, IgG3, IgG4, IgA, and IgA 2. The chain constant domains corresponding to different classes of antibodies are called α, δ, ε, γ, and μ, respectively. The subunit structures and three-dimensional configurations of different classes of immunoglobulins are well known.
"antibody-dependent cell-mediated cytotoxicity" and "ADCC" refer to a cell-mediated reaction in which nonspecific cytotoxic cells that express Fc receptors (FcRs) (e.g., Natural Killer (NK) cells, neutrophils, and macrophages) recognize bound antibody on a target cell and subsequently cause lysis of the target cell. The primary cells mediating ADCC, NK cells, express Fc γ R III only, whereas monocytes express Fc γ R I, Fc γ R II and Fc γ R III. Raveth and Kinet in immunological yearbook 9: FcR expression on hematopoietic cells is summarized in table 3 on pages 457-92(1991), 464. To assess ADCC activity of a molecule of interest, an in vitro ADCC assay may be performed, as described in U.S. patent No. 5,500,362 or 5,821,337. Useful effector cells in such assays include Peripheral Blood Mononuclear Cells (PBMC) and Natural Killer (NK) cells. Alternatively or additionally, ADCC activity of a molecule of interest may be assessed in vivo, for example in Clynes et al pnas (usa) 95: 652-.
A "human effector cell" is a leukocyte that expresses one or more fcrs and performs effector functions. Preferably, the cells express at least fcyr III and perform the function of an ADCC effector. For example, human leukocytes that mediate ADCC include human Peripheral Blood Mononuclear Cells (PBMCs), Natural Killer (NK) cells, monocytes, cytotoxic T cells, and neutrophils; among them, PBMC and NK cells are preferable. Effector cells may be isolated from their natural source, e.g., from blood and PBMCs as described herein.
The term "Fc receptor" or "FcR" is used to describe a receptor that binds to the Fc region of an antibody. A preferred FcR is a native sequence human FcR. Moreover, the preferred fcrs are receptors (gamma receptors) that bind IgG antibodies, including Fc γ R I, Fc γ R II and Fc γ R III subtypes, as well as allelic variants and alternatively spliced forms of these receptors. Fc γ R II receptors include Fc γ R IIA ("activating receptor") and Fc γ R IIB ("inhibiting receptor"), both of which have similar amino acid sequences, differing primarily in their cytoplasmic domains. The activating receptor Fc γ R IIA contains an immunoreceptor tyrosine-based activation motif (ITAM) in its cytoplasmic domain. The inhibitory receptor Fc γ R IIB contains in its cytoplasmic domain an immunoreceptor tyrosine-based inhibitory motif (ITIM) (for review see Daeron, Ann. Rev.Immunol. 15: 203-234 (1997)). In ravatch and Kinet, annual immunology 9: 457-92 (1991); capel et al, immunization methods (immunological methods) 4: 25-34 (1994); and de Haas et al, journal of laboratory and clinical medicine (j.lab.clin.med.) 126: 330-41(1995) for FcR. Other fcrs, including those identified in the future, are encompassed by the term "FcR". The term also includes the neonatal receptor, FcRn, which is responsible for transporting maternal IgG to the fetus (Guyer et al, J Immunol 117: 587(1976) and Kim et al, J Immunol 24: 249 (1994)).
"complement-dependent cytotoxicity" or "CDC" refers to the ability of a molecule to lyse a target in the presence of complement. The complement activation pathway is initiated by the binding of the first component of the complement system (C1q) to a molecule (e.g., an antibody) that forms a complex with a cognate antigen. To assess complement activation, one can use, for example, Gazzano-Santoro et al, J Immunol methods 202: 163(1996) CDC assays were performed.
"native antibodies" are typically heterotetrameric glycoproteins of about 150,000 daltons, composed of two identical light chains (L) and two identical heavy chains (H). Each light chain is linked to a heavy chain by one covalent disulfide bond, whereas the number of disulfide bonds varies among heavy chains of different immunoglobulin isotypes. Each heavy and light chain also has regularly spaced intrachain disulfide bonds. Each heavy chain has a variable domain (VH) at one end thereof, followed by a plurality of constant domains. Each light chain end has a variable domain (VL) and the other end has a constant domain; the light chain constant domain is juxtaposed to the first constant domain of the heavy chain, and the variable domain of the light chain is juxtaposed to the variable domain of the heavy chain. It is believed that specific amino acids form an interface between the variable domains of the light and heavy chains.
The term "variable" means that certain portions of the variable regions of different antibodies differ widely in sequence and that these portions are useful in the binding and specificity of each particular antibody for its particular antigen. However, the distribution of variability is not uniform throughout the variable region of the antibody. It is concentrated in three segments called hypervariable regions of the light and heavy chain variable regions. The more highly conserved portions of the variable regions are called Framework Regions (FR). The variable regions of native light and heavy chains each comprise four FRs, mostly in the beta-sheet configuration, connected by three hypervariable regions which form loops, sometimes partially, with the beta-sheet configuration. The hypervariable regions of each chain are linked in close proximity by FRs and form together with the hypervariable regions of the other chains the antigen-binding site of an antibody (see Kabat et al, sequences of proteins of immunological interest, 5 th edition, public Health Service, National Institutes of Health, Bethesda, Md. (1991)). The constant regions are not directly involved in the binding of antibodies to antigens, but exhibit various effector functions, such as participation of antibodies in antibody-dependent cell-mediated cytotoxicity (ADCC).
The term "hypervariable region" when used herein refers to the amino acid residues of an antibody which are responsible for antigen binding. Hypervariable regions typically contain amino acid residues from the "complementarity determining regions" or "CDRs" (e.g., residues 24-34(L1), 50-56(L2) and 89-97(L3) of the light chain variable region, residues 31-35(H1), 50-65(H2) and 95-102(H3) of the heavy chain variable region, Kabat et al, sequences of proteins of immunological interest, 5 th edition, Public Health Service, National Institutes of Health, Bethesda, MD. (1991)), and/or residues of the "hypervariable loops" (e.g., residues 26-32(L1), 50-52(L2) and 91-96(L3) of the light chain variable region, residues 26-32(H1), 53-55(H2) and 96-101(H3) of the light chain variable region; Chia and Lesk, journal of molecular biology (1987) -. "framework region" or "FR" residues are variable region residues other than the hypervariable region residues defined herein.
Papain digestion of antibodies produces two identical antigen binding fragments, called "Fab" and one residual "Fc" fragment, each Fab fragment having a single antigen binding site, the name of Fc reflecting its ability to readily form crystals. Pepsin treatment produced an F (ab')2A fragment which has two antigen binding sites and which is still capable of cross-linking with an antigen.
"Fv" is the smallest antibody fragment, containing the entire antigen recognition and antigen binding site. This region is a dimer of a heavy and a light chain variable region that are tightly and non-covalently joined. At VH-VLThe surface of the dimer, the three hypervariable regions of each variable region interact conformationally to define an antigen-binding site. The six hypervariable regions together confer antigen-binding properties to the antibody. However, even a single variable domain (or half of an Fv comprising only three antigen-specific hypervariable regions) can recognize and bind antigen with only a lower affinity than the entire binding site.
The Fab fragment also contains the light chain constant region and the first constant region of the heavy chain (CH 1). Fab' differs from Fab fragments in that the carboxy terminus of the heavy chain CH1 domain has been added to several residues, including one or more cysteines from the antibody hinge region. Fab '-SH is used herein to refer to a Fab' in which the cysteine residues of the constant domains have at least one free thiol group. F (ab') 2Antibody fragments were originally produced as Fab' fragment pairs with hinge region cysteines between them. Other chemical linkages of antibody fragments are also known.
The "light chain" of an antibody from any species of vertebrate can be assigned to one of two completely different types, called kappa and lambda, based on their constant region amino acid sequences.
"Single chain Fv" or "scFv" antibody fragments include the V of an antibodyHAnd VLDomains, which are present in a single polypeptide chainThe above. Preferably, the Fv polypeptide is at VHAnd VLThe domains also contain a polypeptide linker between them that enables the scFv to form the structure required for antigen binding. For reviews on scFv see Pluckthun in "pharmacology of monoclonal antibodies", Vol.113, eds Rosenburg and Moore, Springer-Verlag, New York, pp.269-315 (1994). HER2 antibody scFv fragments are described in WO 93/16185; U.S. patent nos. 5,571,894; and U.S. Pat. No. 5,587,458.
The term "bivalent antibodies (diabodies)" refers to small antibody fragments with two antigen binding sites, which fragments are in one polypeptide chain (V)H-VL) Has a heavy chain variable region (V) linked theretoH) And a light chain variable region (V) L). Two antigen binding sites are formed by using a very short linker that prevents pairing of the two domains on the same chain, forcing pairing with the complementary domains on the other chain. In EP 404, 097; WO 93/11161; and Hollinger et al, proceedings of the national academy of sciences USA, 90: 6444-.
A "humanized" form of a non-human (e.g., rodent) antibody is a chimeric antibody comprising minimal sequences derived from non-human immunoglobulins. For the most part, humanized antibodies are human immunoglobulins (recipient) in which residues from a hypervariable region of the recipient are replaced by residues from a hypervariable region of a non-human species, such as mouse, rat, rabbit or non-human primate (donor) antibody), having the desired specificity, affinity, and capacity (capacity). In some cases, human immunoglobulin Framework Region (FR) residues are substituted with corresponding non-human residues. Furthermore, humanized antibodies may comprise residues not found in the recipient antibody or in the donor antibody. These modifications are intended to further refine antibody function. In general, a humanized antibody will comprise substantially all of at least one, and typically two, variable domains, in which all or substantially all of the hypervariable loops correspond to those of a non-human immunoglobulin and all or substantially all of the FRs are those of a human immunoglobulin sequence. The humanized antibody optionally further comprises an immunoglobulin constant region (Fc), typically at least a portion of a human immunoglobulin. Auspicious see Jones et al, Nature 321: 522-525 (1986); riechmann et al, Nature 332: 323-329 (1988); and Presta, curr. op. struct.biol.2: 593-596(1992).
Humanized HER2 antibodies include huMAb4D5-1, huMAb4D5-2, huMAb4D5-3, huMAb4D5-4, huMAb4D5-5, huMAb4D5-6, huMAb4D5-7 and huMAb4D5-8 or TrastuzumabAs described in table 3 of U.S. patent 5,821,337, which is specifically incorporated herein by reference; humanized 520C9(WO93/21319) and humanized 2C4 antibodies described herein.
For purposes herein, "Trastuzumab", is "And "huMAb 4D 5-8" refers to antibodies comprising the light and heavy chain amino acid sequences in SEQ ID NOS.13 and 14, respectively.
Herein, "Pertuzumab," rhuMAb2C4, "and" omnitarget "refer to antibodies comprising the variable light and variable heavy amino acid sequences in SEQ ID nos.3 and 4, respectively. Wherein Pertuzumab is a full-length antibody, preferably it comprises the light and heavy chain amino acid sequences of SEQ ID nos.15 and 16, respectively.
A "naked antibody" is an antibody (as defined herein) that is not conjugated to a heterologous molecule, such as a cytotoxic moiety or a radioactive standard.
An "affinity-matured" antibody is an antibody that has one or more changes in one or more hypervariable regions that result in an increased affinity of the antibody for an antigen compared to a parent antibody that does not have those changes. Preferred affinity matured antibodies will have nanomolar or even picomolar affinity for the target antigen. Affinity-matured antibodies are produced by methods known in the art. Marks et al, Bio/Technology, 10: 779-783(1992) describes affinity maturation by rearrangement of VH and VL domains. Random mutation of CDR and/or framework residues is described by Barbas et al, proc.nat.acad.sci, USA, 91: 3809-3813 (1994); schier et al, Gene, 169: 147-; yelton et al, j.immunol., 155: 1994-2004 (1995); jackson et al, j.immunol., 154 (7): 3310-3319 (1995); and Hawkins et al, j.mol.biol., 226: 889-.
An "agonist antibody" is an antibody that binds to and activates a receptor. In general, the receptor activation capacity of an agonist antibody will be at least qualitatively similar (and may be substantially qualitatively similar) to the natural agonist ligand of the receptor. An example of an agonist antibody is an antibody that binds to a receptor in the TNF receptor superfamily, such as DR5, and which induces apoptosis in cells expressing a TNF receptor (e.g., DR 5). Assays for determining induction of apoptosis are described in WO98/51793 and WO99/37684, both of which are hereby incorporated by reference.
An "isolated" antibody is one that is identified and isolated and/or recovered from a component of its natural environment. Contaminant components of their natural environment are substances that would interfere with diagnostic or therapeutic uses of the antibody, and may include enzymes, hormones, and other proteinaceous or non-proteinaceous solutes. In preferred embodiments, the antibody will be purified (1) to a degree of purification of greater than 95% by weight, and most preferably greater than 99% by weight of the antibody as determined by the Lowry method, (2) to a degree sufficient to obtain an N-terminal or internal amino acid sequence of at least 15 residues by use of a rotating cup sequencer, or (3) to homogeneity by SDS-PAGE under reducing or non-reducing conditions and use of Coomassie blue or, preferably, silver stain. Isolated antibodies include antibodies in situ within recombinant cells, as at least one component of the antibody's natural environment is not present. In general, however, an isolated antibody is prepared by at least one purification step.
A HER2 antibody that "inhibits HER dimerization more effectively than Trastuzumab" is one that attenuates or eliminates HER dimers more effectively (e.g., at least about 2-fold more effectively) than Trastuzumab. Preferably, such antibodies are at least about as effective as murine monoclonal antibody 2C4, a Fab fragment of murine monoclonal antibody 2C4, Pertuzumab, and a Fab fragment of Pertuzumab for inhibiting HER2 dimerization. HER dimerization inhibition can be assessed by direct study of HER dimers, or by assessing HER activation, or downstream signals resulting from HER dimerization, and/or by assessing antibody-HER 2 binding sites, and the like. An assay for screening for antibodies that inhibit HER dimerization more effectively than Trastuzumab is described in Agus et al Cancer Cell 2: 127-137(2002) and WO01/00245(Adams et al). For example, inhibition of HER dimer formation can be assessed, for example (see, e.g., FIGS. 1A-B of Agus et al Cancer Cell 2: 127-137 (2002); and WO 01/00245); attenuation of HER ligand activation in HER dimer-expressing cells (e.g., FIGS. 2A-B of WO01/00245 and Agus et al Cancer Cell 2: 127-137 (2002)); repression of binding of HER ligands to cells expressing HER dimers (e.g., WO01/00245, and FIG. 2E of Agus et al Cancer Cell 2: 127-137 (2002)); inhibition of Cell growth of Cancer cells (e.g., MCF7, MDA-MD-134, ZR-75-1, MD-MB-175, T-47D cells) that express HER dimers in the presence (or absence) of HER ligands (e.g., WO01/00245 and FIGS. 3A-D of Agus et al Cancer Cell 2: 127-137 (2002)); inhibition of downstream signaling (e.g., inhibition of HRG-dependent AKT phosphorylation or inhibition of HRG-or TGF α -dependent MAPK phosphorylation) (see, e.g., WO01/00245, and FIGS. 2C-D of Agus et al Cancer Cell 2: 127-137 (2002)) to determine inhibition of HER dimerization. Whether an antibody inhibits HER dimerization can also be assessed by studying the binding site of antibody HER2, for example, by assessing the structure or model, such as crystal structure, of an antibody that binds HER2 (see, e.g., Franklin et al Cancer Cell 5: 317-.
The HER2 antibody may "inhibit HRG-dependent AKT phosphorylation" and/or "inhibit HRG-or TGF-dependent MAPK phosphorylation" more effectively (e.g., at least 2-fold more effectively) than Trastuzumab (see, e.g., Agus et al Cancer Cell 2: 127-137(2002) and WO 01/00245).
The HER2 antibody may "not inhibit HER2 external domain (ectomain) cleavage" (Molina et al Cancer Res.61: 4744-4749 (2001).
A HER2 antibody that "binds to the heterodimeric binding site of HER 2" binds to residues in domain II (optionally also binds to residues in other HER2 extracellular domains, such as domains I and III) and can sterically hinder, at least to some extent, the formation of HER2-EGFR, HER2-HER3, or HER2-HER4 heterodimers. Franklin et al Cancer Cell 5: 317-.
An antibody that "binds to domain II of HER 2" binds to residues in domain II and optionally binds to other domains of HER2, such as residues in domains I and III. Preferably the antibody binding domain II binds to the linkage between domains I, II and III of HER 2.
As used herein, "growth inhibitory agent" refers to a compound or composition that inhibits the growth of a cell, particularly a HER-expressing cancer cell, in vitro or in vivo. Thus, the growth inhibitory agent may be one that significantly reduces the percentage of HER expressing cells in S phase. Examples of growth inhibitory agents include agents that inhibit cell cycle progression (beyond S phase), such as agents that induce G1 arrest and M-phase arrest. Typical M-phase suppressants include vinca alkaloids (vincas) (vincristine and vinblastine), taxanes, and topological II inhibitors such as doxorubicin, epirubicin (epirubicin), daunorubicin (daunorubicin), etoposide (etoposide), and bleomycin. Those agents that block G1 also extend to S phase blockade, for example, DNA alkylating agents such as tamoxifen, prednisone, dacarbazine (dacarbazine), mechlorethamine (mechlororethamine), cisplatin, methotrexate, 5-fluorouracil, and cytarabine (ara-C). Further information can be found in The Molecular Basis of Cancer, Mendelsohnand Israel, eds., Chapter 1, entitled "Cell cycle regulation, oncogenes, and landinaneoplastic drugs" by Murakami et al (WB Saunders: Philadelphia, 1995), especially page 13.
Examples of "growth inhibitory" antibodies are those that bind to HER2 and inhibit the growth of HER2 cancer cells. A preferred growth inhibitory HER2 antibody inhibits the growth of SK-BR-3 breast tumor cells in cell culture by more than 20%, preferably more than 50% (e.g., from about 50% to about 100%) at an antibody concentration of about 0.5-30 μ g/ml, wherein the growth inhibition is determined after six days of exposure of the SK-BR-3 cells to the antibody (see U.S. Pat. No. 5,677,171 issued 10/14/1997). The SK-BR-3 cell growth inhibition assay is described in greater detail in this patent and below. A preferred growth inhibitory antibody is a humanized variant of murine monoclonal antibody 4D5, e.g., Trastuzumab.
An antibody that "induces apoptosis" refers to an antibody that induces programmed cell death as determined by binding of annexin (annexin) V, DNA fragmentation, cell shrinkage, endoplasmic reticulum swelling, cell fragmentation, and/or formation of a vacuole (known as an apoptotic body). The cell is typically one that expresses the antigen to which the antibody binds. Preferably the cell is a tumor cell. For example, Phosphatidylserine (PS) translocation can be measured by annexin binding; DNA fragmentation can be assessed by DNA gradients; whereas nuclear/chromatin condensation accompanied by DNA fragmentation can be assessed by any growth of hypodiploid cells. Preferably, the antibody that induces apoptosis is one that results in about 2-50 fold, preferably about 5-50 fold, and most preferably about 10-50 fold induction of annexin binding relative to untreated cells in an annexin binding assay that is performed using cells that express the antigen to which the antibody binds. Examples of antibodies that induce apoptosis are HER2 antibodies 7C2 and 7F3, and certain DR5 antibodies.
"epitope 2C 4" is the region in the extracellular domain of HER2 to which antibody 2C4 binds. To screen for Antibodies that bind the epitope of 2C4, a conventional cross-blocking assay can be performed, such as the assay described in Antibodies, A Laboratory Manual, Cold Spring Harbor Laboratory, Ed Harlow and DavidLane (1988). Alternatively, epitope mapping can be performed to assess whether an antibody binds to the 2C4 epitope of HER 2. Epitope 2C4 comprises residues from domain II in the extracellular domain of HER 2. 2C4 and Pertuzumab bind the extracellular domain of HER2 at the junction of domains I, II and III. Franklin et al human cancer cell 5: 317-328(2004).
"epitope 4D 5" is the region in the extracellular domain of HER2 to which antibody 4D5(ATCC CRL10463) and Trastuzumab bind. This epitope is close to the transmembrane domain of HER2 and within domain IV of HER 2. To screen for Antibodies that bind the epitope of 4D5, a conventional cross-blocking assay can be performed, such as the assay described in Antibodies, available Manual, Cold Spring harbor laboratory, Ed harbor and David Lane (1988). Alternatively, epitope mapping can be performed to assess whether the antibody binds to the 4D5 epitope of HER2 (e.g., any one or more residues in the region from about residue 529 to about residue 625 of HER2, including residue 529 and residue 625).
"epitope 7C2/7F 3" is an amino-terminal region within domain I of the extracellular domain of HER2 to which 7C2 and/or 7F3 antibodies (both deposited under ATCC, see below) bind. To screen for Antibodies that bind the epitope 7C2/7F3, a conventional cross-blocking assay can be performed, such as the assay described in Antibodies, A Laboratory Manual, Cold Spring Harbor Laboratory, Ed Harlow and DavidLane (1988). Alternatively, epitope mapping can be performed to confirm whether the antibody binds to the 7C2/7F3 epitope on HER2 (e.g., any one or more residues in the region from about residue 22 to about residue 53 of HER 2).
"treatment" refers to both therapeutic treatment and prophylactic measures. The person in need of treatment includes persons already suffering from the disease as well as persons to be protected from the disease. Thus, a patient to be treated herein may be diagnosed as having a disease or as likely predisposed to, or predisposed to, the disease.
The terms "cancer" and "cancerous" refer to or describe the physiological state of a mammal that is generally characterized by unregulated cell growth. Examples of cancer include, but are not limited to, carcinoma, lymphoma, blastoma (including medulloblastoma and retinoblastoma), sarcoma (including liposarcoma and synovial cell sarcoma), neuroendocrine tumors (including carcinoid tumors, gastrinoma, and islet cell carcinoma), mesothelioma, schwannomas (including acoustic neuroma), meningioma, adenocarcinoma, melanoma, and leukemia or lymphoid malignancies. More specific examples of such cancers include squamous cell cancer (e.g., epithelial squamous cell cancer), lung cancer including small-cell lung cancer, non-small cell lung cancer, adenocarcinoma of the lung and squamous carcinoma of the lung, cancer of the peritoneum, hepatocellular cancer, gastrointestinal cancer including gastrointestinal cancer, pancreatic cancer, glioblastoma, neck cancer, ovarian cancer, liver cancer, bladder cancer, liver cancer, breast cancer, colon cancer, rectal cancer, colorectal cancer, endometrial or uterine cancer, salivary gland carcinoma, kidney cancer, prostate cancer, vulval cancer, thyroid cancer, hepatic carcinoma, anal cancer, penile cancer, scrotal cancer, esophageal cancer, tumors of the biliary tract, and cancers of the head and neck.
The term "effective amount" refers to an amount of a drug that is effective against the disease in a patient. When the disease is cancer, the effective amount of the drug may reduce the number of cancer cells; reducing tumor size; inhibit (i.e., delay and preferably stop to some extent) cancer cell infiltration into peripheral organs; inhibit (i.e., delay and preferably stop to some extent) tumor metastasis; inhibit tumor growth to some extent; and/or alleviate one or more symptoms associated with cancer to some extent. To the extent that the drug can prevent the growth of cancer cells and/or kill existing cancer cells, it can be cytostatic and/or cytotoxic. The effective amount may prolong progression free survival, result in a target response (including a partial response, PR, or complete response, CR), increase overall survival time, and/or ameliorate one or more symptoms of cancer.
A "HER 2 expressing cancer" is a cancer comprising cells having a HER2 protein present on their cell surface.
A cancer that "overexpresses" a HER receptor is one that has significantly higher levels of HER receptor, such as HER2, at its cell surface compared to a noncancerous cell of the same tissue type. Such overexpression may be caused by gene amplification or by enhanced transcription or translation. HER receptor overexpression can be determined in diagnostic or prognostic assays by assessing increased levels of HER protein present on the cell surface (e.g.by immunohistochemical assays; IHC). Alternatively, or in addition, the level of HER encoding nucleic acid in the cell may be measured, for example, by fluorescence in situ hybridization (FISH; see WO98/45479 published at 10 months 1998), southern blotting, or Polymerase Chain Reaction (PCR) techniques, such as timed quantitative PCR (RT-PCR). HER receptor overexpression can also be studied by measuring the exudation of antigens in biological fluids such as serum (see, e.g., U.S. Pat. No. 4,933,294 issued to 1990-06-12; WO91/05264 issued to 1991-04-18; U.S. Pat. No. 5,401,638 issued to 1995-03-28; and Sias et al J.Immunol. methods 132: 73-80 (1990)). In addition to the above assays, the skilled practitioner can also utilize various in vivo assays. For example, cells in a patient may be exposed to an antibody, which is optionally labeled with a detectable label, such as a radioisotope, and binding of the antibody to cells in the patient may be assessed, for example, by external scanning for radioactivity or by analysis of biopsy tissue taken from a patient previously exposed to the antibody.
In contrast, a cancer that "does not overexpress the HER2 receptor" is one that does not express higher than normal levels of HER2 receptor as compared to a noncancerous cell of the same tissue type.
A cancer that "overexpresses" a HER ligand is one that produces significantly higher levels of the ligand as compared to non-cancerous cells of the same tissue type. Such overexpression may be caused by gene amplification or by enhanced transcription or translation. Overexpression of a HER ligand can be determined diagnostically by assessing the level of the ligand (or nucleic acid encoding it) in the patient, for example in tumor biopsy or by various diagnostic assays such as IHC, FISH, southern blot, PCR or the in vivo assays described above.

The "tumor necrosis factor receptor superfamily" or "TNF receptor superfamily" herein refers to receptor polypeptides bound by cytokines of the TNF family. Typically, these receptors are type I transmembrane receptors with one or more cysteine rich repeats in their extracellular domain. The TNF receptor superfamily can be further subdivided into (1) death receptors; (2) a decoy (decoy) receptor; and (3) a signal receptor lacking a death domain. The "death receptor" comprises in its cytoplasm or intracellular region a "death domain", i.e. a region or sequence that acts to transduce a signal in the cell that can lead to apoptosis or induction of certain genes. The "decoy receptor" lacks a functional death domain and is unable to transduce signals that lead to apoptosis. Examples of cytokines in the TNF gene family include tumor necrosis factor-alpha (TNF-alpha), tumor necrosis factor-beta (TNF-beta or lymphotoxin), CD30 ligand, CD27 ligand, CD40 ligand, OX-40 ligand, 4-1BB ligand, Apo-1 ligand (also known as Fas ligand or CD95 ligand), Apo-2 ligand (also known as TRAIL), Apo-3 ligand (also known as TWEAK), Osteoprotegerin (OPG), APRIL, RANK ligand (also known as TRANCE), and TALL-1 (also known as BlyS, BAFF or THANK). Examples of receptors in the TNF receptor superfamily include: tumor necrosis factor receptor type 1 (TNFR1), tumor necrosis factor receptor type 2 (TNFR2), p75 Nerve Growth Factor Receptor (NGFR), B cell surface antigen CD40, T cell antigen OX-40, Apo-1 receptor (also known as Fas or CD95), Apo-3 receptor (also known as DR3, swl-1, TRAMP and LARD), receptor known as "transmembrane activator and CAML-interactor" or "TACI"), BCMA protein, DR4, DR5 (or known as Apo-2; TRAIL-R2, TR6, Tango-63, hA 8, TRICK2 or KILLER), DR6, DcR1 (also known as TRID, LIT or TRAIL-R3), DcR2 (also known as TRAIL-R4 or TRUNDD), DCG, DcR3 (also known as TNFR 6 or M68), CAR 72, HVATAR 72 or TNFR1, TNFR 369872, TNFR1, TNFR 369872, TNFR and LARD, 371A1) In that respect
The terms "Apo-2 ligand", "Apo-2L", "Apo 2L", Apo-2 ligand/TRAIL "and" TRAIL "are used interchangeably herein and refer to a polypeptide sequence comprising amino acid residue 114 and 281 of the amino acid sequence shown in figure 24(SEQ ID No.46), including 95 to 281, including residues 92 to 281, including residues 91 to 281, including residues 41 to 281, including residues 39 to 281, including residues 15 to 281, or including residues 1 to 281, as well as biologically active fragments, deletions, insertions, and/or substitution variants of the above sequences. In one embodiment, the polypeptide sequence comprises residues 114-281 of FIG. 24(SEQ ID No. 46). Optionally, the polypeptide sequence comprises residues 92-281 or residues 91-281 of figure 24(SEQ ID No. 46). An Apo-2L polypeptide may be encoded by the natural nucleotide sequence shown in figure 24(SEQ ID No. 45). Optionally, the codon encoding residue Prol19 (FIG. 24; SEQ ID No.45) may be "CCT" or "CCG". Optionally, the fragment or variant is biologically active and has at least about 80% amino acid sequence identity, or at least about 90% sequence identity, or at least 95%, 96%, 97%, 98%, or 99% sequence identity to any of the above sequences. This definition includes substituted variants of Apo-2 ligand in which at least one of its natural amino acids is substituted with another amino acid, such as an alanine residue. This definition also includes naturally-occurring sequence Apo-2 ligands isolated from Apo-2 ligand sources or prepared by recombinant and/or synthetic methods. Apo-2 ligands of the invention include polypeptides known as Apo-2 ligands or TRAIL disclosed in WO97/01633 published as 1997-01-16, WO97/25428 published as 1997-07-17, WO 99/36535 published as July 22, 1999-07-22, WO 01/00832 published as 2001-01-04, WO 02/09755 published as 2002-02-07, WO 00/75191 published as 2000-12-14, and US patent No. 6,030,945 published as 2000-02-29. The term is generally used to refer to monomeric, dimeric, trimeric, hexamer or highly oligomeric forms comprising the polypeptide. The numbering used to refer to the amino acid residues of the Apo-2L sequence is according to FIG. 24(SEQ ID No.46), unless otherwise specifically stated.
"Apo-2 ligand receptors" include receptors referred to in the art as "DR 4" and "DR 5". Pan et al describe members of the TNF receptor family known as "DR 4" (Pan et al, Science, 276: 111-113 (1997); see also WO98/32856, 1998-07-30, WO 99/37684, 1999-07-29, WO 00/73349, 2000-12-07, US6,433,147, 2002-08-13, US6,461,823, 2002-10-08, and US6,342,383, 2002-01-29). Sheridan et al, Science, 277: 818, 821(1997) and Pan et al, Science, 277: 815-818(1997) describe another receptor for Apo2L/TRAIL (see also WO98/51793, published as 1998-11-19; WO98/41629, published as 1998-09-24). Such receptors are designated DR5 (or the receptor is also designated Apo-2; TRAIL-R, TR6, Tango-63, hAPO8, TRICK2 or KILLER; Screaton et al, curr. biol., 7: 693-containing 696 (1997); Walczak et al, EMBO J., 16: 5386-5387 (1997); Wu et al, Nature Genetics, 17: 141-143 (1997); WO98/35986, 1998-10-14, EP870, 827, 1998-10-22, WO98/46643, 1999-01-21, WO99/02653, 1999-02-25, WO99/09165, 1999-03-11, 2002-11791, 2002-08-13, US 0072091, 1999-2002-12-2002/0098550, 1998-2001-07, 1998-2-68508, 1998-11, US-2001-2-68502-68508, 1998-2001-07 01255540; US 2002/0160446 published 2002-10-31, US 2002/0048785 published 2002-04-25; US6,569,642 issued 2003-05-27, US6,072,047 issued 2000-06-06, US6,642,358 issued 2003-11-04). As noted above, other receptors for Apo-2L include DcR1, DcR2, and OPG. The term "Apo-2L receptor" as used herein includes native sequence receptors and receptor variants. These terms encompass Apo-2L receptors expressed in many mammals, including humans. The Apo-2L receptor may be expressed endogenously, as occurs naturally in the germline of many human tissues, or may be expressed by recombinant or synthetic means. A "native sequence Apo-2L receptor" comprises a polypeptide having the same amino acid sequence as that derived from a native Apo-2L receptor. Thus, a native sequence Apo-2L receptor may have the amino acid sequence of a naturally occurring Apo-2L receptor from any mammal, including a human. Such native sequence Apo-2L receptors may be isolated from nature or may be produced by recombinant or synthetic means. The term "native sequence Apo-2L receptor" specifically includes naturally occurring truncated or secreted forms of the receptor (e.g., comprising, for example, a soluble form of the extracellular domain sequence), naturally occurring variant forms (e.g., other spliced forms), and naturally occurring allelic variants. Receptor variants may include fragments or deletion mutants of the native sequence Apo-2L receptor. FIGS. 25A-C show the 411 amino acid sequence of the human DR5 receptor disclosed in WO98/51793 for 1998-11-19, and its nucleotide sequence (SEQ ID Nos.47 and 48). Transcriptional splice variants of the human DR5 receptor are known in the art. This splice variant encodes the 440 amino acid sequence of the human DR5 receptor shown in FIGS. 26A-C, and its nucleotide sequence (SEQ ID Nos.49 and 50), as disclosed in WO98/35986 of 1998-08-20.
As used herein, "death receptor antibody" refers generally to an antibody to a receptor in the tumor necrosis factor receptor superfamily and comprising a death domain capable of producing an apoptotic signal, such antibodies including the DR5 antibody and the DR4 antibody.
The use of "DR 5 receptor antibody", "DR 5 antibody", or "anti-DR 5 antibody" in a broad sense is intended to refer to an antibody that binds at least one form of the DR5 receptor or extracellular domain thereof. Optionally the DR5 antibody is fused or linked to a heterologous sequence or molecule. Preferably the heterologous sequence allows or facilitates formation of a higher order or oligomeric complex by the antibody. Optionally, the DR5 antibody binds to the DR5 receptor but does not bind or cross-react with any other Apo-2L receptor (e.g., DR4, DcR1, or DcR 2). Optionally the antibody is an agonist of DR5 signaling activity.
Optionally, the DR5 antibodies of the invention bind to the DR5 receptor at a concentration range of about 0.1nM to about 20mM, as measured in a BIAcore binding assay. Optionally, the DR5 antibodies of the invention exhibit IC50 values of about 0.6nM to about 18mM as measured in a BIAcore binding assay.
For purposes of this document only, the term "Apomab" refers to an agonist antibody that binds DR5 and comprises the variable heavy and variable light amino acid sequences of SEQ id nos.55 and 56. Preferably the Apomab comprises the heavy and light chains of SEQ ID nos.51 and 52, respectively.

Exemplary molecular targets of the antibodies encompassed by the invention include CD proteins such as CD3, CD4, CD8, CD19, CD20, CD22, CD34, and CD 40; a member of the ErbB receptor family such as the EGF receptor, HER2, HER3 or HER4 receptor; b cell surface antigens, such as CD20 or BR 3; members of the tumor necrosis receptor superfamily, including DR 5; prostate Stem Cell Antigen (PSCA); cell adhesion molecules such as LFA-1, Macl, p150.95, VLA-4, ICAM-1, VCAM, α 4/β 7 integrin, and α v/β 3 integrin, including their α or β subunits (e.g., anti-CD 11 a; anti-CD 18 or anti-CD 11b antibodies); growth factors such as VEGF and its receptors; tissue Factor (TF); tumor Necrosis Factor (TNF) such as TNF- α or TNF- β, interferon- α (IFN- α); interleukins, such as IL-8; IgE; a blood group antigen; flk2/flt3 receptor; obesity (OB) receptors; an mpl receptor; CTLA-4; protein C, and the like.
Soluble antigens or fragments thereof, optionally conjugated to other molecules, can be used as immunogens for antibody production. For transmembrane molecules, such as receptors, fragments of these (e.g., the extracellular domain of the receptor) can be used as immunogens. Alternatively, cells expressing transmembrane molecules can be used as immunogens. Such cells may be from natural sources (e.g., cancer cell lines) or may be cells transformed by recombinant techniques to express the transmembrane molecule. Other antigens and their various forms that can be used to make antibodies will be apparent to those skilled in the art.
To produce HER2 antibody, the HER2 antigen for its production may be, for example, a soluble form of the extracellular domain of HER2 or a portion thereof, which comprises the desired epitope. Alternatively, a cell expressing HER2 on its cell surface (e.g., a transformed NIH-3T3 cell overexpressing HER 2; or a cancer cell line such as SK-BR-3 cell, see Stancovski et al PNAS (USA) 88: 8691-8695(1991)) can be used to generate antibodies.
(ii) Monoclonal antibodies
Monoclonal antibodies are obtained from a population of substantially homogeneous antibodies, i.e., the individual antibodies comprising the population are identical and/or bind the same epitope, except for possible variants that may be generated during monoclonal antibody production. Thus, the modifier "monoclonal" indicates that the antibody is not characteristic of a different antibody composition.
For example, Kohler, nature 256: 495(1975) or monoclonal antibodies can be prepared by recombinant DNA methods (U.S. patent No. 4816567).
In the hybridoma method, a mouse or other suitable host animal, such as a hamster, is immunized as described above to induce lymphocytes that produce or are capable of producing antibodies that specifically bind to proteins used in the immunization. Alternatively, lymphocytes may be immunized in vitro and then fused with myeloma cells using an appropriate fusing agent such as polyethylene glycol to form hybridoma cells (Goding, monoclonal antibody: principles and applications, pp.59-103(Academic Press, 1986)).
The hybridoma cells so prepared are seeded and cultured in a suitable culture medium that preferably includes one or more substances that inhibit the growth or survival of the unfused parental myeloma cells. For example, if the parental myeloma cells lack hypoxanthine guanine phosphoribosyl transferase (HGPRT or HPRT), the culture medium for the hybridomas typically includes hypoxanthine, aminopterin, and thymidine (HAT medium), which substances prevent the growth of HGPRT-deficient cells.
Preferred myeloma cells are those which fuse efficiently, support stable production of high levels of antibodies by the selected antibody-producing cells, and are sensitive to HAT or the like medium. Among the preferred myeloma Cell lines are murine myeloma Cell lines, such as those derived from MOPC-21 and MPC-11 mouse tumors (from the Salk Institute Cell Distribution Center, san Diego, Calif., USA) and SP-2 or X63-Ag8-653 cells (American type culture Collection, Rockville, Md., USA). Human hybridoma cells and mouse-human heterogeneous hybridoma cell lines have also been reported for the production of human monoclonal antibodies (Kozbor, J. Immunol, 133: 3001 (1984); Brodeur et al, monoclonal antibody production techniques and applications, pp 51-63 (Marcel Dekker, Inc., New York, 1987)).
Determining the production of monoclonal antibodies to said antigen in hybridoma cell growth medium. Preferably, the binding specificity of monoclonal antibodies produced by hybridoma cells is determined by immunoprecipitation or an in vitro binding assay, such as Radioimmunoassay (RIA) or enzyme-linked immunosorbent assay (ELISA).
The binding affinity of a monoclonal antibody can be determined, for example, by Munson et al, anal. 220(1980) by Scatchard analysis.
After hybridoma cells producing antibodies with the desired specificity, affinity, and/or activity are identified, the clones may be subcloned by limiting dilution methods and cultured by standard methods (Goding, monoclonal antibodies: principles and applications, pp.59-103, Academic Press, 1986)). Suitable media for this purpose include, for example, D-MEM or RPMI-1640 medium. In addition, hybridoma cells can grow in animals to form ascites tumors.
Monoclonal antibodies secreted by the subclones are suitably isolated from the culture medium, ascites fluid or serum by conventional immunoglobulin purification methods, such as protein A-Sepharose, hydroxylapatite chromatography, gel electrophoresis, dialysis or affinity chromatography.
DNA encoding a monoclonal antibody can be readily isolated and sequenced by conventional methods (e.g., using oligonucleotide probes that specifically bind to genes encoding the heavy and light chains of the monoclonal antibody). The hybridoma cells may serve as a preferred source of such DNA. Once the DNA has been isolated, it is ligated into an expression vector, which is then transformed into a host cell, such as an E.coli cell, simian COS cell, Chinese Hamster Ovary (CHO) cell, or myeloma cell that does not produce immunoglobulin protein, to synthesize monoclonal antibodies in the recombinant host cell. A review of DNA for recombinant expression of antibody-encoding DNA in bacteria includes Skerra et al, curr. 256-charge 262(1993) and Pl ü ckthun, Immunol. Revs., 130: 151-188(1992).
In another embodiment, monoclonal antibodies or antibody fragments may be isolated from antibody phage libraries used in McCafferty et al, nature 348: 552 and 554. Clackson et al, Nature 352: 624-: 581-597(1991) describes the isolation of murine and human antibodies using phage libraries, respectively. The subsequent literature describes the generation of high affinity (nM range) human antibodies as a strategy for constructing large phage libraries by chain shuffling (Marks et al, Bio/technology, 10: 779-2263 (1992)) and combinatorial infection and in vivo recombination (Waterhouse et al, nucleic acid research, 21: 2265-2266 (1993)). Thus, these techniques are alternatives to conventional monoclonal antibody hybridoma techniques for the isolation of monoclonal antibodies.
The DNA may also be modified, for example, by replacing the murine homologous sequences with sequences encoding the human heavy and light chain constant regions (U.S. Pat. No. 4816567; Morrison et al, Proc. Natl. Acad. Sci. USA 81: 6851(1984)), or by covalently linking all or part of the coding sequence for a non-immunoglobulin polypeptide to the coding sequence for an immunoglobulin.
Typically, such immunoglobulin polypeptides have been produced as chimeric bivalent antibodies, which include one antigen binding site specific for one antigen, and another antigen binding site having specificity for a different antigen, in place of the constant region of an antibody, or in place of the variable region of one antigen binding site of an antibody.
(iii) Humanized antibodies
Methods for humanizing non-human antibodies have been described in the art. Preferably, the humanized antibody has one or more amino acid residues of non-human origin introduced. These non-human amino acid residues are often "import" residues, which are typically derived from "import" variable regions. Humanization can be substantially performed by replacing murine CDR or CDR sequences with those of the human antibody according to the method of Winter and coworkers (Jones et al, Nature, 321: 522-525 (1986); Riechmann et al, Nature 332: 323-327 (1988); Verhoeyen et al, science 239: 1534-1536 (1988)). Thus, such "humanized" antibodies are chimeric antibodies (U.S. patent No. 4816567) in which substantially less than the entire human variable region is replaced by a corresponding sequence derived from a non-human species. In practice, humanized antibodies are typically human antibodies in which some CDR residues and some FR residues are replaced by residues from analogous sites in the odontoblastic antibody.
The choice of human heavy and light chain variable regions for use in making humanized antibodies is important for reducing antigenicity. According to the so-called "best-fit" approach, a complete library of known human variable region sequences can be screened for the variable region sequences of rodent antibodies. The human sequence most closely related to the rodent sequence is then used as the Framework (FR) for the humanized antibody (Sims et al, J. Immunol. 151: 2296 (1993); Chothia et al, J. molecular biology. 196: 901 (1987)). Another approach employs specific frameworks derived from the common sequence of all human antibodies of a specific subgroup of light or heavy chains. The same framework can be used for several different humanized antibodies (Carter et al, Proc. Natl. Acad. Sci. USA 89: 4285 (1992); Presta et al, J. Immunol., 151: 2623 (1993)).
It is even more important that the antibodies are humanized and retain high affinity for the antigen and other good biological activity. To achieve this, according to a preferred method, the parental sequences and various conceptual humanized products are analyzed using three-dimensional models of the parental and humanized sequences, by which method humanized antibodies are prepared. Three-dimensional immunoglobulin models are publicly available and well known to those skilled in the art. Computer programs have been developed which allow the specification and display of the possible three-dimensional conformational structures of selected candidate immunoglobulin sequences. Observation of these indications allows analysis of the likely role of the residues in the function of the candidate immunoglobulin sequence, i.e., analysis of residues that affect the ability of the candidate immunoglobulin to bind antigen. In this way, FR residues can be screened from the receptor and combined with important sequences to obtain desired antibody properties, such as enhanced affinity for the target antigen. In general, CDR residues are directly and predominantly involved in the effect on antigen binding.
WO 01/00245 describes the production of an exemplary humanized HER2 antibody that binds to HER2 and suppresses ligand activation of the HER receptor. The humanized antibodies of particular interest herein are substantially as effective as murine monoclonal antibody 2C4 (or a Fab fragment thereof) in blocking EGF, TGF- α and/or HRG mediated activation of MAPK, and/or as effective as murine monoclonal antibody 2C4 (or a Fab fragment thereof) in binding HER 2. The humanized antibodies herein may, for example, comprise non-human hypervariable region residues incorporated into a human variable heavy domain and may further comprise a Framework Region (FR) substitution at a position selected from 69H, 71H and 73H, using the variable domain numbering system given in Kabat et al, Sequence of Protein of immunological Interest, 5th ed. In one embodiment, the humanized antibody comprises FR substitutions at two or all of positions 69H, 71H and 73H.
The exemplary humanized antibodies of interest herein comprise the variable heavy domain complementarity determining residue GFTFTDYTMX, wherein X is preferably D or S (SEQ ID No. 7); DVNPNSGGSIYNQRFKG (SEQ ID No. 8); and/or NLGPSFYFDY (SEQ ID No.9), optionally comprising amino acid modifications of those CDR residues, e.g., wherein the modifications substantially retain or increase the affinity of the antibody. For example, the antibody variant of interest may have from about one to about seven or about five amino acid substitutions in the above variable heavy CDR sequences. Such antibody variants can be prepared, for example, by affinity maturation as described below. Most preferred humanized antibodies comprise the variable heavy domain amino acid sequence of SEQ ID No. 4.
In addition to those variable heavy domain CDR residues in the preceding paragraph, the humanized antibody may comprise, for example, variable light domain complementarity determining residue KASQDVSIGVA (SEQ ID No. 10); SASYXXX, wherein X at position 5 is preferably R or L, wherein X at position 6 is preferably Y or E and X at position 7 is preferably T or S (SEQ ID No. 11); and/or QQYYIYPYT (SEQ ID No. 12). Such humanized antibodies optionally comprise amino acid modifications of the above CDR residues, e.g., wherein the modifications substantially maintain or enhance the affinity of the antibody. For example, the antibody variant of interest may have from about one to about seven or about five amino acid substitutions in the above variable light CDR sequences. Such antibody variants can be prepared, for example, by affinity maturation as described below. Most preferred humanized antibodies comprise the variable light domain amino acid sequence of SEQ ID No. 3.
The application also relates to affinity matured antibodies that bind to HER2 and suppress ligand activation of the HER receptor. The parent antibody may be a human or humanized antibody, e.g., an antibody comprising variable light and/or heavy sequences of SEQ ID nos.3 and 4, respectively (i.e., variant 574). The affinity matured antibody preferably binds to the HER2 receptor with an affinity that is better than murine 2C4 or variant 574 (e.g., from about two-fold or about four-fold, to about 100-fold or about 1000-fold enhanced affinity, e.g., as assessed using HER 2-extracellular domain (ECD) ELISA). Exemplary substituted variable heavy CDR residues include H28, H30, H34, H35, H64, H96, H99, or a combination of two or more (e.g., two, three, four, five, six, or seven of these residues). Examples of variable light CDR residues that are altered include L28, L50, L53, L56, L91, L92, L93, L94, L96, L97, or combinations of two or more (e.g., two, three, four, five, up to about ten of these residues).
Various forms of humanized or affinity matured antibodies are claimed. For example, the humanized or affinity matured antibody may be an antibody fragment, such as a Fab, which is optionally conjugated to one or more cytotoxic agents to produce an immunoconjugate. Alternatively, the humanized antibody or affinity matured antibody may be a full length antibody, such as a full length IgG1 antibody.
(iv) Human antibodies
In addition to humanization, human antibodies can be prepared. For example, transgenic animals (e.g., mice) have now been generated that, upon immunization, produce all of the components of human antibodies without the production of endogenous immunoglobulins. For example, chimeric and germline (germ-line) mutant mice have been reported to have a heavy chain joining region (J) in the antibodyH) Homozygous deletion of the gene results in complete suppression of endogenous antibody production. Transfer of human germline immunoglobulin gene arrays into such germline mutant mice will result in the production of human antibodies as a result of antigen challenge. See, e.g., Jakobovits et al, proceedings of the national academy of sciences USA, 90: 2551 (1993); jakobovits et al, Nature, 362: 255-258 (1993); bruggermann et alYear in immune.7: 33 (1993); and us patent nos. 5591669, 5589369 and 5545807.
Alternatively, phage display techniques (McCafferty et al, Nature 348: 552-553(1990)) can be used to generate human antibodies and antibody fragments in vitro from all components of immunoglobulin variable (V) region genes from unimmunized donors. According to this technique, antibody V region genes are cloned in the same framework as the major or minor capsid protein genes of filamentous bacteriophage (e.g., M13 or fd) and displayed as functional antibody fragments on the surface of the phage particle. Since the filamentous particle contains a single-stranded DNA copy of the phage genome, selection based on the functional characteristics of the antibody also results in selection of the gene encoding the antibody exhibiting these properties. Thus, the phage mimics some of the characteristics of the B cell. Phage display can be performed in a variety of formats; for a review, see, e.g., Johnson, Kevin s. and Chiswell, David j., recent Opinion in Structural Biology (Current Opinion in Structural Biology) 3: 564-571(1993). Phage display can be performed using several sources of V gene fragments. Clackson et al, Nature, 352: 624-628(1991) A diverse array of anti-oxazolone antibodies was isolated from a small random combinatorial library of spleen-derived V genes from immunized mice. Basically, the molecular biology journal 222: 581-597(1991), or Griffith et al, EMBOJ.12: 725-734(1993) construct all the components of the V gene of an unimmunized human donor and isolate antibodies against an antigen diversity array (including self-antigens). See also U.S. patent nos. 5565332 and 5573905.
As described above, human antibodies can also be produced by activated B cells in vitro (see U.S. Pat. nos. 5,567,610 and 5,229,275).
Human anti-HER 2 antibodies are described in U.S. Pat. No. 5772997, published at 30/6/1998 and WO97/00271, published at 3/1/1997.
(v) Antibody fragments
Various techniques for generating antibody fragments have been developed. Traditionally, these fragments are eliminated by proteolysis of intact antibodiesChemosynthesis (see Morimoto et al, Journal of Biochemical and Biophysical Methods 24: 107-117(1992)) and Brennan et al, science 229: 81(1985)). But these fragments can now be produced directly by recombinant host cells. For example, antibody fragments can be isolated from the antibody phage libraries described above. Alternatively, Fab '-SH fragments can be recovered directly from E.coli and chemically ligated to form F (ab')2Fragments (Carter et al, Bio/technology 10: 163-167 (1992)). According to another method, F (ab') can be isolated directly from recombinant host cell culture2And (3) fragment. Other techniques for producing antibody fragments will be apparent to those skilled in the art. In other embodiments, the antibody of choice is a single chain Fv fragment (scFv). See WO 93/16185; us patent 5,571,894; and U.S. patent 5,587,458. The antibody fragment may also be a "linearized antibody," as described in U.S. Pat. No. 5,641,870. Such linearized antibody fragments may be monospecific or bispecific.
(vi) Bispecific antibodies
Bispecific antibodies are antibodies that have binding specificities for at least two different epitopes. Exemplary bispecific antibodies can bind to two different epitopes of the HER2 protein. Other such antibodies may combine the HER2 binding site with a binding site for EGFR, HER3, and/or HER 4. Alternatively, the anti-HER 2 arm may be bound to an arm that binds to a trigger molecule on a leukocyte, such as a T cell receptor molecule (e.g., CD2 or CD3), or an IgG Fc receptor (fcyr) such as fcyri (CD64), fcyrii (CD32), and fcyriii (CD16), thereby focusing on the cellular defense mechanisms of cells expressing HER 2. Bispecific antibodies can also be used to localize cytotoxic agents to cells expressing HER 2. These antibodies have a HER2 binding arm and an arm that binds a cytotoxic agent (e.g. saporin, anti-INF-alpha, vinca alkaloid, ricin a chain, methotrexate or radioisotope hapten). Bispecific antibodies can be prepared as full length antibodies or antibody fragments (e.g., F (ab')2Bispecific antibodies).
WO 96/16673 describes bispecific HER 2/FcyRIII antibodies, while in U.S. Pat. No. 5837234 the bispecific ErbB 2/FcyRI antibody IDM1(Osidem) is disclosed. Bispecific HER2/Fc α antibodies are described in WO 98/02463. Bispecific HER2/CD3 antibodies are taught in U.S. patent 5821337. MDX-210 is a bispecific HER2-Fc γ RIII Ab.
Methods of making bispecific antibodies are known in the art. The traditional approach to the preparation of complete bispecific antibodies is based on the co-expression of two immunoglobulin heavy-light chain pairs, where the two chains have different specificities (Millstein et al, Nature 305: 537-539 (1983)). Due to the random distribution of immunoglobulin heavy chain light chains, these hybridomas (cell hybridomas (quadroma)) may produce a mixture of 10 different antibody molecules, only one of which has the correct bispecific structure. The purification of the correct molecule, which is usually performed by an affinity chromatography step, is very complicated and yields are low. Similar methods are described in WO93/08829 and Traunecker et al, EMBO J, 10: 3655-3659(1991).
According to different methods, the variable region of an antibody with the desired binding specificity (antibody-antigen binding site) is fused to an immunoglobulin constant region sequence. The fusion is preferably to an immunoglobulin heavy chain constant region comprising at least a portion of the hinge region, the CH2 and CH3 regions. Preferably, the first heavy chain constant region (CH1) containing the site required for light chain binding is present in at least one fusion. The DNA encoding the immunoglobulin heavy chain fusion and, if desired, the immunoglobulin light chain can be inserted into different expression vectors and co-transfected into an appropriate host organism. This allows, in embodiments constructed using unequal ratios of the three polypeptide chains, greater flexibility in adjusting the mutual ratios of the three polypeptide fragments to achieve optimal yields. However, it is also possible to insert the coding sequences for two or all three polypeptide chains into one expression vector when at least two polypeptide chains are expressed in equal proportions to achieve high yields or when said proportions are of no particular significance.
In a preferred embodiment of this method, the bispecific antibody is composed of a hybrid immunoglobulin heavy chain with a first binding specificity in one arm and a hybrid immunoglobulin heavy chain-light chain pair (providing a second binding specificity) in the other arm. This asymmetric structure has been found to be advantageous for the separation of the desired bispecific compound from a mixture of non-essential immunoglobulin chains, since the presence of immunoglobulin light chains on only half of the bispecific molecule makes the separation easier. This method is disclosed in WO 94/04690. For further details of the preparation of bispecific antibodies, see Suresh et al, methods enzymology, 121: 210(1986).
According to another approach described in U.S. Pat. No. 5,731,168, the interface between a pair of antibody molecules can be engineered to maximize the percentage of heterodimers obtained from recombinant cell culture. Preferred interfaces include at least a portion of the antibody constant region CH3 domain. In this method, one or more small side chains of amino acids derived from the interface of the first antibody molecule are replaced by larger side chains (e.g., tyrosine or tryptophan). Complementary "grooves" of the same or similar size to the large side chains can be formed at the interface of the second antibody molecule by substituting the large side chain of an amino acid with a small side chain (e.g., alanine or threonine). This results in higher yields of heterodimers than the undesired end products like homodimers.
Bispecific antibodies include cross-linked antibodies or "heteroconjugated" antibodies. For example, one of the antibodies in the heteroconjugate can be conjugated to avidin and the other antibody conjugated to biotin. It is thought that such antibodies may be used to target immune cells to unwanted cells (U.S. Pat. No. 4676980), and may also be used to treat HIV infection (WO91/00360, WO92/200373, EP 03089). Heteroconjugate antibodies can be prepared by any suitable cross-linking method. Suitable crosslinking formulations and various crosslinking techniques are known in the art and are disclosed in U.S. Pat. No. 4676980.
Techniques for making bispecific antibodies from antibody fragments have also been described in the literature. For example, bispecific antibodies can be prepared using chemical ligation. Brennan et al, science 229: 81(1985) the proteolytic preparation of F (ab')2A method for fragmenting. These fragments are complexed with dimercapto as arsenicSodium is reduced in the presence of sodium to stabilize adjacent sulfhydryl groups and prevent intermolecular disulfide bond formation. The resulting Fab' fragments are converted to thio-nitrobenzoate (TNB) derivatives. One Fab ' -TNB derivative is reduced into Fab ' -thiol by mercaptoethylamine, and then mixed with other Fab ' -TNB derivatives with equal molecular weight to form the dual-specific antibody. The bispecific antibody thus produced can be used as a reagent for selective immobilization of enzymes.
Recent advances have facilitated the direct recovery of Fab' -SH fragments from E.coli, which can be chemically coupled to form bispecific antibodies. Shalaby et al, journal of experimental medicine, 175: 217-225(1992) describes fully humanized bispecific antibodies F (ab')2The generation of molecules. Each Fab' fragment was separately secreted from E.coli and directly chemically coupled in vitro to form bispecific antibodies. The bispecific antibody prepared in the way can be combined with cells which excessively express HER2 receptor and normal human T cells, and can also trigger the lytic activity of human cytotoxic lymphocytes on human breast tumor cells. Various techniques for preparing and isolating bispecific antibody fragments directly from recombinant cell culture have also been described. For example, bispecific antibodies can be made with leucine zippers. Kostelny et al, J Immunol, 148 (5): 1547-1553(1992)). Leucine zipper peptides from the Fos and Jun proteins were linked to the Fab' portions of two different antibodies by gene fusion. The antibody homodimers are reduced to monomers in the hinge region and then re-oxidized to form antibody heterodimers. The method can also be used to prepare antibody homodimers. By Hollinger et al, proceedings of the national academy of sciences USA, 90: 6444- > 6448(1993)) provides an alternative method for the preparation of bispecific antibody fragments. The fragment contains heavy chain variable region (V) H) Which is linked to the light chain variable region (V) via a linkerL) Connected, the linker is very short, making pairing between the two domains of the same strand impossible. Thus, V on the same fragmentHAnd VLThe domains are forced to complement V on the other fragmentLAnd VHThe domains pair, thereby forming two antigen binding sites. Another report has been madeStrategy for the preparation of bispecific antibodies using single chain fv (sFv) dimers. See Gruber et al, journal of immunology, 152: 5368(1994).
Antibodies of more than two valencies are contemplated. For example, a trispecific antibody can be prepared. Tutt et al, journal of immunology, 147: 60(1991).
(vii) Other amino acid sequence modifications
Amino acid sequence modifications of the antibodies described herein are contemplated. For example, it may be desirable to improve the binding affinity and/or other biological characteristics of an antibody. Amino acid sequence variants of an antibody can be prepared by introducing appropriate nucleotide changes in the antibody nucleic acid or by peptide synthesis. Such modifications include, for example, deletions from, and/or insertions into, and/or substitutions of, residues within the amino acid sequence of the antibody. Any combination of deletions, insertions, and substitutions can be made to arrive at the final construct, so long as the final construct possesses the desired properties. The amino acid changes can also alter post-translational processing of the antibody, for example, changing the number or position of glycosylation sites.
One useful method of identifying certain residues or regions of an antibody at preferred positions for mutagenesis is Cunningham and Wells, science 244: 1081-1085(1989) described in "alanine scanning mutagenesis". Here, a residue or group of target residues (e.g., charged residues such as arginine, aspartic acid, histidine, lysine and glutamic acid) are identified and substituted with neutral or negatively charged amino acids (most preferably alanine or polyalanine) in order to affect the interaction of the amino acid with the antigen. Those amino acid positions that demonstrate functional sensitivity to substitution are improved by introducing further or additional variants at the point of substitution. Thus, while the site of introduction of an amino acid sequence variation is predetermined, the nature of the mutation itself need not be predetermined. For example, to analyze the effect of a mutation at a given site, alanine scanning or random mutagenesis is performed at the target codon or region and the expressed antibody variants are screened for the desired activity.
Amino acid sequence insertions include amino-and/or carboxy-terminal fusions ranging in length from one residue to polypeptides comprising 100 or more residues, as well as insertions of single or multiple amino acid residues within the sequence. Examples of terminal insertions include an antibody with an N-terminal methionyl residue or such an antibody fused to a cytotoxic polypeptide. Other insertional variants of the antibody molecule include the fusion of the N-or C-terminus of the antibody to an enzyme or polypeptide that increases the serum half-life of the antibody.
Another class of variants are amino acid substitution variants. These variants have at least one amino acid residue in the antibody molecule substituted with a different residue. Sites of greatest interest for substitution mutagenesis include hypervariable regions, and changes in FR can also be considered. Conservative substitutions are shown in table 1 under the heading "preferred substitutions". If these substitutions result in a change in biological activity, more substantial changes from the "substitution examples" column in Table 1, or further more substantial changes described in the amino acid classification below, can be introduced and the products screened.

Substantial modification of antibody biological properties is achieved by selecting substitutions that differ significantly in their effect of maintaining (a) the polypeptide backbone structure of the substitution region, e.g., as a sheet or helical conformation, (b) the charge or hydrophobicity of the molecule at the target site, or (c) the size of the side chain. Amino acids can be grouped according to the similarity of their side chain properties (in A.L. Lehninger, in Biochemistry, second ed., pp.73-75, Worth Publishers, New York (1975)):
(1) Non-polar: ala (A), Val (V), Leu (L), Ile (I), Pro (P), Phe (F), Trp (W), Met (M)
(2) Uncharged polarity: gly (G), Ser (S), Thr (T), Cys (C), Tyr (Y), Asn (N), Gln (Q)
(3) Acidity: asp (D), Glu (E)
(4) Alkalinity: lys (K), Arg (R), His (H)
Alternatively, naturally occurring residues may be divided into groups based on common side chain properties:
(1) hydrophobic type: norleucine, met, ala, val, leu, ile;
(2) neutral hydrophilic type: cys, ser, thr;
(3) acidity: asp, glu;
(4) alkalinity: asn, gln, his, lys, arg;
(5) chain orientation affecting residues: gly, pro; and
(6) an aromatic group: trp, tyr, phe.
Non-conservative substitutions will define the replacement of a member of one of the above classes by another class.
Any cysteine residues not involved in maintaining the correct conformation of the antibody may also be substituted, usually with serine, to improve the oxidative stability of the molecule and prevent aberrant cross-linking. Conversely, cysteine linkages may be added to the antibody to improve its stability (particularly when the antibody is an antibody fragment such as an FV fragment).
A particularly preferred type of substitution variant comprises substitution of one or more residues of a hypervariable region of the parent antibody. Typically, the variant selected for further development should have improved biological activity relative to its parent antibody. One convenient way to generate such substitution variants is to use affinity maturation by phage display. Briefly, several sites (e.g., 6-7 sites) of a hypervariable region are mutated to generate all possible amino acid substitutions at each site. The antibody variants so produced are displayed in monovalent form on filamentous phage particles as fusions to the M13 gene III product packaged within each particle. The phage-displayed variants are then screened for biological activity (e.g., binding affinity) as described herein. To identify alternative hypervariable region modification sites, residues of a hypervariable region which contribute predominantly to antigen binding can be identified by alanine scanning mutagenesis. Furthermore, it is also advantageous to analyze the crystal structure of the antigen-antibody complex to determine the contact points between the antigen and the antibody. These contact residues and their adjacent residues are candidates for substitution according to the techniques described herein. Once such variants are generated, they are all screened as described herein, and antibodies with advantageous properties in one or more relevant experiments are selected for further development.
Another type of amino acid variant of the antibody alters the original glycosylation pattern of the antibody. The alteration is the removal of one or more carbohydrate moieties from the antibody and/or the addition of one or more glycosylation sites not otherwise present in the antibody.
Glycosylation of antibodies is typically either N-linked or O-linked. N-linked refers to linking a carbohydrate moiety to the side chain of an asparagine residue. The tripeptide sequences asparagine-X-serine and asparagine-X-threonine (where X is any amino acid except proline) are recognition sequences for enzymatic attachment of a carbohydrate moiety to an asparagine side chain. Thus, the presence of any of the above tripeptide sequences in a polypeptide may create potential glycosylation sites. O-linked glycosylation refers to the attachment of N-acetylgalactosamine, galactose, or xylose to a hydroxyamino acid, primarily serine, threonine, but 5-hydroxyproline and 5-hydroxylysine may also be used.
The addition of glycosylation sites to the antibody can be achieved by altering the amino acid sequence to include one or more of the above-described tripeptide sequences (in the case of the addition of an N-linked glycosylation site). Such changes may also be achieved by adding or substituting one or more serine or threonine residues in the sequence of the original antibody (in the case of addition of an O-linkage).
When the antibody comprises an Fc region, the carbohydrate attached thereto may be altered. For example, antibodies having a mature sugar structure lacking trehalose attached to the Fc region of the antibody are described in U.S. patent application No. US 2003/0157108a1, Presta, L. See also US2004/0093621a1(Kyowa Hakko Kogyo co., Ltd). Antibodies having bisecting N-acetylglucosamine (GlcNAc) in the sugar attached to the Fc region of the antibody are mentioned in WO03/011878, Jean-Mairet et al and U.S. Pat. No. 6,602,684, Umana et al. Antibodies having at least one galactose residue in an oligosaccharide attached to the Fc region of an antibody are reported in WO97/30087, Patel et al. See also, WO98/58964(Raju, S.) and WO99/22764(Raju, S.), which relate to antibodies having varying sugars attached to their Fc regions.
Nucleic acid molecules encoding amino acid sequence variants of antibodies are prepared by various methods known in the art. These methods include, but are not limited to, isolation from a natural source (in the case of natural amino acid sequence variants), or preparation by oligonucleotide-mediated (or site-directed) mutagenesis, PCR mutagenesis, and cassette mutagenesis of an earlier prepared variant or non-variant form of the anti-ErbB 2 antibody.
(viii) Screening for antibodies with desired Properties
Techniques for generating antibodies have been described above. Antibodies having certain biological properties may be further selected as desired.
To identify an antibody that inhibits ligand activation of a HER receptor, the antibody can be assayed for its ability to suppress binding of the HER ligand to a cell expressing the HER receptor (e.g., to bind to another HER receptor that forms a HER hetero-oligomer with the HER receptor of interest). For example, cells that naturally express, or that after transfection express HER receptor of HER hetero-oligomers may be incubated with an antibody and subsequently exposed to a labeled HER ligand. The HER2 antibody can then be evaluated for its ability to inhibit ligand binding to HER receptors in HER heteromers.
For example, inhibition of HRG binding to MCF7 breast tumor cell line by HER2 antibody can be performed using a monolayer on ice MCF7 culture in 24-well plates essentially as described in WO 01/00245. The HER2 monoclonal antibody can be added to each well and incubated for 30 minutes. May subsequently be added125I-labelled rHRG beta 1177-224(25pm), the incubation may be continued for 4 to 16 hours. Dose response curves can be prepared and IC calculated for the target antibody50The value is obtained. In one embodiment, an antibody that suppresses ligand activation of a HER receptor will have an IC of about 50nM or less, more preferably 10nM or less, in such an assay 50To inhibit HRG binding to MCF7 cells. Wherein the antibody is an antibody fragment such as a Fab fragment, inhibiting HRG binding to IC of MCF7 cells in such an assay50May be, for example, about 100nM or less, more preferably 50nM or less.
Alternatively, or in addition, the ability of the HER2 antibody to suppress HER ligand-stimulated tyrosine phosphorylation of a HER receptor present in a HER heteromultimer can be assessed. For example, cells endogenously expressing HER receptors or expressing them after transfection can be incubated with antibodies and subsequently assayed for HER ligand-dependent tyrosine phosphorylation activity using an anti-phosphotyrosine monoclonal, which is optionally conjugated with a detectable label. HER receptor activation and suppression of this activity by antibodies can also be determined using the kinase receptor activation assay described in U.S. patent No. 5,766,863.
In one embodiment, antibodies can be screened for that inhibit HRG stimulation of p180 tyrosine phosphorylation in MCF7 cells substantially as described in WO 01/00245. For example,MCF7 cells can be seeded in 24-well plates and monoclonal antibodies against HER2 can be added to each well and incubated for 30 minutes at room temperature; rHRG beta 1 may then be added 177-244Added to each tube to a final concentration of 0.2nM and incubation may be continued for 8 minutes. The medium was aspirated from each well and the reaction was stopped by adding 100. mu.l of SDS sample buffer (5% SDS, 25mM DTT, and 25mM Tris-HCl, pH 6.8). Each sample (25. mu.l) can be electrophoresed on a 4-12% gradient gel (Novex) and subsequently electrophoresed onto a polyvinylidene fluoride membrane. Anti-phosphotyrosine (at 1. mu.g/ml) immunoblots can be developed and M can be quantified by reflection densitometryrThe predominance over 180,000 reflects the intensity of the band. The selected antibodies will preferably significantly inhibit HRG stimulation of p180 tyrosine phosphorylation to approximately 0-35% of the control in this assay. HRG-stimulated inhibitory dose response curves for p180 tyrosine phosphorylation as measured by reflection densitometry can be prepared and IC's for the target antibodies can be calculated50. In one embodiment, an antibody that suppresses ligand activation of a HER receptor will have an IC of about 50nM or less, more preferably 10nM or less50To inhibit HRG stimulation of p180 tyrosine phosphorylation in this assay. When the antibody is an antibody fragment, such as a Fab fragment, IC50About 100nM or less, more preferably 100nM or less, in order to inhibit HRG stimulation of p180 tyrosine phosphorylation in this assay.
The growth inhibitory effect of the antibodies on MDA-MB-175 cells may also be assessed, for example, substantially as described in Schaefer et al Oncogene 15: 1385-1394 (1997). According to this assay, MDA-MB-175 cells may be treated with HER2 monoclonal antibody (10. mu.g/mL) for 4 days and stained with crystal violet. Incubation with HER2 antibody may show growth inhibitory effects on this cell line, similar to that demonstrated for monoclonal antibody 2C 4. In another embodiment, exogenous HRG will not significantly reverse this inhibition. Preferably, the antibody will be capable of inhibiting cell proliferation of MDA-MB-175 cells to a greater extent than monoclonal antibody 4D5 (optionally to a greater extent than monoclonal antibody 7F 3) in the presence and absence of exogenous HRG.
In one embodiment, the HER2 antibody of interest may suppress the heregulin-dependent association of HER2 with HER3 in MCF7 and SK-BR-3 cells as determined in a co-immunoprecipitation experiment as described in WO01/00245, which suppression is substantially more effective than monoclonal antibody 4D5, and preferably substantially more effective than monoclonal antibody 7F 3.
To identify growth inhibitory HER2 antibodies, antibodies can be screened that inhibit the growth of cancer cells that overexpress HER 2. In one embodiment, the growth inhibitory antibody is selected to be capable of inhibiting the growth of SK-BR-3 cells in cell culture by about 20-100% and preferably by about 50-100%, with an antibody concentration of about 0.5-30 μ g/ml. To identify such antibodies, an SK-BR-3 assay as described in U.S. Pat. No. 5,677,171 can be performed. According to this assay, SK-BR-3 cells were grown in a 1:1 mixture of F12 and DMEM medium supplemented with 10% fetal bovine serum, glutamate and penicillin streptomycin. SK-BR-3 cells were seeded at 20,000 cells in 35mm cell culture dishes (2mls/35mm dish). HER2 antibody was added at 0.5-30. mu.g/ml per dish. Six days later, the electronic COULTER is utilized TMThe cell counter compares the number of cells to the number of untreated cells. Those antibodies that inhibit the growth of SK-BR-3 cells by about 20-100% or by about 50-100% can be selected as growth inhibitory antibodies. Assays for screening growth inhibitory antibodies, such as 4D5 and 3E8, are described in U.S. patent No. 5,677,171.
To select HER2 antibodies that induce apoptosis, annexin binding assays can be performed using BT474 cells. BT474 cells were cultured and plated on petri dishes as described in the previous paragraph. The medium was then removed and replaced with fresh medium alone or medium containing 10 μ g/ml monoclonal antibody. After a three-day incubation period, the monolayers were washed with PBS and detached by trypsinization. The cells were subsequently centrifuged and resuspended in Ca2+Combined in buffer and aliquoted into tubes as discussed above for the cell death assay. The tubes then receive labeled annexin (e.g., annexin)White V-FTIC) (1. mu.g/ml). Can utilize FACSCANTMFlow cytometer and FACSCVERTTMCellQuest software (Becton Dickinson) was used to analyze the samples. Those antibodies that induced a statistically significant level of annexin binding relative to the control were selected as apoptosis-inducing antibodies. In addition to the annexin binding assay, a DNA staining assay using BT474 cells can also be utilized. To perform this assay, BT474 cells treated with the antibody of interest as described in the previous two paragraphs were incubated with 9. mu.g/ml HOECHST33342 TMIncubating at 37 deg.C for 2hr, and then using MODFIT LTTMSoftware (Verity software House) at EPICS ELITETMAnalysis was performed on a flow cytometer (Coulter Corporation). Using this assay, antibodies can be selected as pro-apoptotic antibodies that induce a 2-fold or greater (preferably 3-fold or greater) change in the percentage of apoptotic cells than would be the case with untreated cells (up to 100% apoptotic cells). Screening for HER2 antibodies that induce apoptosis, such as assays for 7C2 and 7F3, is described in WO 98/17797.
To screen for antibodies to an epitope on HER2 that is bound by an Antibody of interest, a conventional cross-suppression assay can be performed, as described in Antibody, a Laboratory Manual, Cold Spring harbor Laboratory, Ed harbor and David Lane (1988), to assess whether an Antibody cross-suppresses an Antibody, such as 2C4 or Pertuzumab, binding to HER 2. Alternatively, or in addition, epitope mapping may be performed by methods known in the art and/or the antibody-HER 2 structure (Franklin et al Cancer Cell 5: 317-328(2004)) may be studied to see what domain of HER2 is bound by the antibody.
(ix) Immunoconjugates
The invention also relates to immunoconjugates comprising an antibody conjugated to a cytotoxic drug such as a chemotherapeutic drug, a toxin (e.g., a small molecule toxin or an enzymatically active toxin of bacterial, fungal, plant or animal origin, including fragments and/or variants thereof), or a radioisotope (i.e., a radioconjugate).
Chemotherapeutic agents useful in preparing such immunoconjugates are as described above. Also contemplated herein are conjugates of an antibody and one or more small molecule toxins, such as calicheamicin, maytansine (U.S. Pat. No. 5,208,020), trichothecene (trichothene), CC 1065.
In a preferred embodiment of the invention, the antibody is conjugated to one or more maytansine molecules (e.g., about 1 to about 10 maytansine molecules per antibody molecule). Maytansinoid can be converted to May-SS-Me and then reduced to May-SH3 and reacted with modified antibodies (Chari et al, cancer Res. 52: 127-131(1992)) to produce maytansinoid-antibody conjugates.
Another immunoconjugate of interest comprises an HER2 antibody conjugated to one or more calicheamicin molecules. The calicheamicin family of antibiotics are capable of producing double-stranded DNA breaks at sub-pM concentration levels. Calicheamicin structural analogs that can be used include, but are not limited to gamma1 1、α2 1、α3 1N-acetyl-gamma1 1PSAG and θ1 1(Hinmam et al, cancer research 53: 3336-3342(1993) and Lode et al, cancer research 58: 2925-2928 (1998)). See also U.S. Pat. nos. 5,714,586; 5,712,374; 5,264,586 and 5,773,001, which are incorporated herein by reference.
Enzymatically active toxins and fragments thereof that may be used include: diphtheria toxin a chain, non-binding active fragments of diphtheria toxin, exotoxin a chain (from pseudomonas aeruginosa), ricin a chain, abrin a chain, modeccin a chain, alpha-sarcin, aleurites fordii protein, dianthin protein, phytolacca americana protein (PAPI, PAPII, PAP-S), momordica charantia (momordia) inhibitor, curcin, crotin, saponaria officinalis (sapaonaria officinalis) inhibitor, gelonin, mitomycin (mitogellin), restrictocin, phenomycin, enomycin, and trichothecenes (tricothecenes). See, for example, WO93/21232, published on month 10 and 28, 1993.
The invention also relates to an immunoconjugate formed between an antibody and a compound having nucleolytic activity (such as a ribonuclease or a DNA endonuclease such as a deoxyribonuclease; DNase).
A variety of radioisotopes are useful in preparing radioconjugated antibodies, examples include At211、I131、I125、Y90、Re186、Re188、Sm153、Bi212、P32And radioactive isotopes of Lu.
Conjugates of the antibody and cytotoxic agent may be attached by a variety of bifunctional protein coupling agents such as: n-succinimidyl-3- (2-pyridyldimercapto) propionate (SPDP), succinimidyl-4- (N-maleimidomethyl) cyclohexane-1-carboxylate, Iminothiolane (IT), bifunctional derivatives of imidoesters (such as dimethyl imidoadipate hydrochloride), active esters (such as disuccinimidyl suberate), aldehydes (such as glutaraldehyde), bis-azido compounds (such as bis (p-azidobenzoyl) hexanediamine), bis-diazonium derivatives (such as bis- (p-diazoniumbenzoyl) -ethylenediamine), diisocyanates (such as tolylene 2, 6-diisocyanate), and bis-active fluorine compounds (such as 1, 5-difluoro-2, 4-dinitrobenzene). For example, a ricin immunotoxin may be identified as vietta et al, science 238: 1098 (1987). C14-labeled 1-isothiocyanatobenzyl-3-methyldiethylene triaminopentaacetic acid ester (MX-DTPA) is an exemplary coupling agent for coupling radionucleotide to an antibody. See WO 94/11026. Such a linker may be a "breakable linker" which facilitates release of the cytotoxic drug within the cell. For example, acid labile linkers, peptidase-sensitive linkers, dimethyl linkers, or disulfide-containing linkers can be used (Chari et al, cancer Res. 52: 127- "131 (1992)).
In another embodiment, the antibody may be conjugated to a "receptor" (e.g., streptavidin) for use in tumor pretargeting, and the antibody-receptor conjugate administered to the patient, followed by removal of unbound conjugate from circulation with a clearing agent, and administration of a "ligand" (e.g., avidin) conjugated to a cytotoxic agent (e.g., a radionucleotide).
(x) Other antibody modifications
Additional modifications to the antibodies are contemplated herein. For example, the antibody may be crosslinked with a non-protein polymer, such as polyethylene glycol, polypropylene glycol, polyoxyalkylene (polyoxyalkylene), or a copolymer of polyethylene glycol and polypropylene glycol. Antibodies can also be coated in microcapsules prepared by coacervation techniques or interfacial polymerization (e.g., hydroxymethylcellulose or gelatin microcapsules and poly- (methylmethacylate) microcapsules, respectively), colloidal drug delivery systems (e.g., liposomes, albumin spheroids, microemulsions, nanoparticles, and nanocapsules), or macroemulsions (macroemulsions) as disclosed in Remingtons' Pharmaceutical Sciences, 16 th edition, Oslo, a.
It may be desirable to modify the antibodies of the invention in terms of effector function to enhance the antigen-dependent cell-mediated cytotoxicity (ADCC) and/or complement-dependent cytotoxicity (CDC) of the antibody. This can be achieved by introducing one or more amino acid substitutions in the Fc region of the antibody. Alternatively or in addition, cysteine residues may be introduced in the Fc region, thereby forming interchain disulfide bonds in this region. The homodimeric antibody so produced may have improved internalization capacity and/or increased complement-mediated cell killing capacity and antibody-dependent cellular cytotoxicity (ADCC). See Caron et al, j.exp med.176: 1191-1195(1992) and shop, B.J.Immunol.148: 2918-2922(1992). Also, for example, Wolff et al Cancer Research 53: 2560 2565(1993), heterodimeric antibodies with enhanced antitumor activity were prepared using heterodimeric functional cross-linkers. Alternatively, antibodies can be engineered to have a dual Fc region, potentially enhancing complement lysis and ADCC capabilities. See Stevenson et al, Anti-Cancer Drug Design 3: 219-230(1989).
WO00/42072(Presta, L) describes antibodies with improved ADCC function in the presence of human effector cells, wherein the antibodies comprise amino acid substitutions in their Fc region. Preferably, the antibody with increased ADCC comprises a substitution at position 298, 333, and/or 334 of the Fc region. Preferably the altered Fc region is a human IgG1Fc region comprising or consisting of a substitution at one, two or three of these positions.
Antibodies with altered C1q binding and/or Complement Dependent Cytotoxicity (CDC) are described in WO99/51642, U.S. patent No. 6,194,551B1, U.S. patent No. 6,242,195B1, U.S. patent No. 6,528,624B1, and U.S. patent No. 6,538,124(Idusogie et al). The antibody comprises an amino acid substitution at one or more of amino acid positions 270, 322, 326, 327, 329, 313, 333 and/or 334 of its Fc region.
For example, to increase the serum half-life of an antibody, a salvage receptor binding epitope can be incorporated into an antibody (particularly an antibody fragment) as described in U.S. patent No. 5,739,277. As used herein, the term "salvage receptor binding epitope" refers to an epitope of the Fc region of an IgG molecule responsible for increasing serum half-life in vivo (e.g., IgG1,IgG2,IgG3Or IgG 4). Antibodies with substitutions in their Fc region and increased serum half-life are also described in WO00/42072(Presta, L).
Engineered antibodies having three or more (preferably four) functional antigen binding sites are also contemplated (U.S. application No. US2002/0004587a1, Miller et al).
The HER2 antibodies disclosed herein can also be formulated as immunoliposomes. The compositions are prepared by methods known in the art, such as those described in Epstein et al, proc.natl.acad.sci.usa, 82: 3688 (1985); hwang et al, proc.natl acad.sci.usa, 77: 4030 (1980); U.S. patent nos. 4,485,045 and 4,544,545; and methods described in WO97/38731 published on days 1997-1-23, to prepare antibody-containing liposomes. Liposomes with improved turnover times are disclosed in U.S. Pat. No. 5,013,556.
Particularly useful liposomes can be generated by reverse phase evaporation methods with lipid compositions comprising phosphatidylcholine, cholesterol and PEG-derivatized phosphatidylethanolamine (PEG-PE). Liposomes are pressed through a filter of defined pore size to produce liposomes of the desired diameter. As in Martin et al j.biol.chem.257: 286-288(1982), Fab' fragments of the antibodies of the invention may be coupled to liposomes by disulfide interactions. Optionally, a chemotherapeutic agent is contained in the liposomes. See Gabizon et al J.national Cancer Inst.81(19)1484 (1989).

(xi) Antibody variant compositions
In at least one aspect, the invention relates to a formulation comprising a composition comprising a mixture of a major species of antibody and one or more variants thereof. When the main species antibody binds HER2, preferably the HER2 antibody (one or both of the main component HER2 antibody and antibody variants thereof) is an antibody that binds to domain II of HER2, inhibits HER dimerization more effectively than Trastuzumab, and/or binds to the heterodimeric binding site of HER 2. Preferred embodiments of the main species of antibody herein are antibodies comprising the variable light and variable heavy amino acid sequences of SEQ ID Nos.3 and 4, most preferably comprising a light chain amino acid sequence selected from SEQ ID Nos. 15 and 23, and a heavy chain amino acid sequence selected from SEQ ID Nos.16 and 24.
In one embodiment, the formulated HER2 antibody composition comprises a mixture of the major component HER2 antibody and amino acid sequence variants thereof comprising an amino-terminal directed extension. Preferably, the amino-terminal guide extends on a light chain of the antibody variant (e.g., on one or both light chains of the antibody variant). The main component HER2 antibody or antibody variant may be a full-length antibody or antibody fragment (e.g. Fab of a F (ab') 2 fragment), but preferably both are full-length antibodies. The antibody variants herein may comprise an amino-terminal directed extension on any one or more of their heavy or light chains. Preferably, the amino-terminal guide extends on one or both light chains of the antibody. The amino-terminal directed extension preferably comprises or consists of VHS-. The presence of an amino-terminal-directed extension in a composition can be detected by a variety of analytical techniques, including, but not limited to, N-terminal sequence analysis, charge heterogeneity determination (e.g., cation exchange chromatography or capillary zone electrophoresis), mass spectrometry, and the like. The amount of antibody variant in the composition typically ranges from an amount that constitutes the detection limit of any assay used to detect the variant (preferably N-terminal sequence analysis) to an amount that is less than the main species of antibody. Typically about 20% or less (e.g., from about 1% to about 15%, e.g., from 5% to about 15%) of the antibody molecules in the composition comprise an amino-terminal leader extension. Preferably using quantitative N-terminal sequence analysis or cation exchange analysis (preferably using a high resolution, weak cation exchange column, such as PROPAC WCX-10 TMCation exchange column) to determine such percentage amounts. In addition to amino-terminal directed extension variants, other major classes of antibodies and/or variants are included with amino acid sequence variations, including but not limited to antibodies comprising a C-terminal lysine residue on one or both of its heavy chains, deamidated antibody variants, and the like.
In addition, the main species antibody or variant may further comprise glycosylation variations, non-limiting examples include HER2 antibody comprising a G1 or G2 oligosaccharide structure attached to its Fc region, HER2 antibody comprising a sugar moiety attached to its light chain (e.g., one or two sugar moieties attached to one or two light chains of the antibody), HER2 antibody comprising an aglycosylated heavy chain.
Preparation of the formulations
In a first aspect, the present invention provides a stable pharmaceutical formulation comprising a monoclonal antibody, preferably a full length human or humanized IgG1 antibody, in histidine-acetate buffer at ph5.5-6.5, preferably at ph 5.8-6.2. However, the antibody in the formulation may be an antibody fragment comprising an antigen-binding region, such as a Fab or F (ab') 2 fragment.
In another embodiment, the present invention relates to a pharmaceutical formulation comprising or consisting essentially of: from about 10mg/mL to about 250mg/mL of full-length IgG1 antibody that is susceptible to deamidation or aggregation; histidine-acetate buffer, pH5.5-6.5; a sugar selected from trehalose and sucrose in an amount of about 60mM to about 250 mM; and polysorbate 20 in an amount of about 0.01% to about 0.1%.
In yet another embodiment, the invention provides a pharmaceutical formulation comprising an antibody that binds to domain II of HER2, a sugar and a surfactant in a histidine buffer at a pH of from about 5.5 to about 6.5. For example, the formulation may comprise Pertuzumab in an amount from about 20mg/mL to about 40mg/mL, a histidine-acetate buffer, sucrose, and polysorbate 20, wherein the pH of the formulation is from about 5.5 to about 6.5.
In another aspect, the present invention provides a pharmaceutical formulation comprising a DR5 antibody in histidine buffer at a pH of from about 5.5 to about 6.5, a sugar and a surfactant. Such a formulation may, for example, comprise Apomab, histidine-acetate buffer, trehalose, and polysorbate 20 in an amount from about 10mg/mL to about 30mg/mL, wherein the pH of the formulation is from about 5.5 to about 6.5.
The formulation is particularly useful for antibodies that are prone to deamidation and/or aggregation and/or fragmentation, as the buffer blocks deamidation and/or aggregation and/or fragmentation of the antibody formulated therein. Furthermore, unlike other histidine buffers prepared using HCl, the histidine-acetate buffer lacks the chloride ions found beneficial herein because such buffers have the same protective effect on antibodies as polysorbate 20 when combined with sugars, and are stable and can be stored in stainless steel jars. Thus, in addition to formulations that themselves contain antibodies that are susceptible to deamidation and/or aggregation and/or fragmentation, the invention also provides methods of attenuating deamidation, aggregation and/or fragmentation of a therapeutic monoclonal antibody (e.g., relative to a composition at a different pH or in a different buffer), comprising formulating the antibody in a histidine-acetate buffer, pH 5.5-6.5. In this embodiment, deamidation, aggregation and/or fragmentation may be determined or measured before or after formulating an antibody that exhibits acceptable deamidation, aggregation and/or fragmentation in the formulation and upon storage thereof.
The antibody in the formulation may bind to an antigen, including but not limited to: HER2, CD20, IgE, DR5, BR3 and VEGF.
When the formulated antibody binds HER2, it preferably binds to domain II of HER2, inhibits HER dimerization more effectively than Trastuzumab, and/or binds to the heterodimeric binding site of HER 2. A preferred embodiment of the HER2 antibody herein is an antibody comprising the variable light and variable heavy amino acid sequences in SEQ ID nos.3 and 4, most preferably the light and heavy chain amino acid sequences in SEQ ID nos.15 and 16 (Pertuzumab).

The most preferred DR5 antibody is Apomab.
Each of the above mentioned formulations comprises a buffer, preferably a histidine buffer, most preferably a histidine-acetate buffer, ph5.5-6.5, preferably 5.8-6.2, e.g. about 6.0. The concentration of the buffer is dictated at least in part by the desired pH. Exemplary concentrations of the buffer are from about 1mM to about 200mM, preferably from about 10mM to about 40mM, and most preferably about 20 mM.
The concentration of antibody in the formulation is preferably from about 10mg/mL to about 250 mg/mL. Antibody concentrations can be determined according to the desired use and mode of administration of the formulation. For example, when the formulation is for IV administration (e.g., HER2 antibody), the concentration of antibody in the formulation is preferably from about 20mg/mL to about 40 mg/mL. In an exemplary formulation of Pertuzumab intended for Intravenous (IV) administration, the antibody concentration is from about 20mg/mL to about 40mg/mL, most preferably about 30 mg/mL.
Higher concentrations of antibody may be required when the antibody is used for SQ or IM administration (e.g., for anti-IgE antibodies). Such substantially high antibody concentrations may be from about 50mg/mL to about 250mg/mL, or from about 80mg/mL to about 250mg/mL, or from about 100mg/mL to about 200 mg/mL.
When the formulation comprises a DR5 antibody, such as Apomab, exemplary antibody concentrations are from about 10mg/mL to about 30mg/mL, e.g., about 20mg/mL DR5 antibody; such formulations may be used for intravenous administration.
The formulation for administration is preferably an aqueous formulation (not lyophilized) and has not been previously lyophilized. Although the formulation may be lyophilized, it is preferred that it not be subjected to lyophilization. However, the freezing of aqueous preparations which are not simultaneously dried during the lyophilization process is particularly claimed, which facilitates their longer term storage, for example in stainless steel cans.
The formulation preferably further comprises a sugar, most preferably a disaccharide such as trehalose or sucrose. Typically contain an amount of sugar that reduces the formation of soluble aggregates such as those that occur after freezing/thawing. Exemplary sugar concentrations are from about 10mM to about 1M, for example from about 60mM to about 250mM, most preferably about 120mM, for a HER2 antibody formulation, and about 240mM for a DR5 antibody formulation.
Although the formulation comprising histidine-acetate buffer and sugar is found herein to be stable, the formulation optionally further comprises a surfactant, such as a polysorbate, most preferably polysorbate 20. Typically comprising an amount of surfactant that reduces soluble aggregate formation (as occurs upon shaking or transport). The surfactant concentration is preferably from about 0.0001% to about 1.0%, most preferably from about 0.01% to about 0.1%, for example about 0.02%.
Optionally, the formulation does not contain substantial amounts of salts such as sodium chloride.
The formulations are generally sterile and this may be accomplished according to methods known to those skilled in the art for making pharmaceutical formulations suitable for administration to human subjects, including filtration through sterile filtration membranes, either before or after preparation of the formulation.
In addition, it is desirable that the formulation is stable upon storage. The skilled artisan can determine the stability of the formulation using a variety of stability assays. For example, the formulation may be a formulation that is stable under the following storage conditions: at about 40 ℃ for at least 4 weeks; at about 5 ℃ or about 15 ℃ for at least 3 months or at least 1 year; and/or about-20 ℃ for at least 3 months. Stability can be tested by assessing the physical stability, chemical stability, and/or biological activity of the antibody in the formulation, either at formulation or after storage at the temperature. Physical and/or stability can be assessed qualitatively and/or quantitatively in a number of different ways, including assessing aggregate formation (e.g., using size exclusion chromatography, by measuring turbidity, and/or by visual inspection); (ii) assessing charge heterogeneity by using cation exchange chromatography or capillary zone electrophoresis; amino-terminal or carboxy-terminal sequence analysis; mass spectrometry analysis; SDS-PAGE analysis to compare reduced and intact antibodies; peptide mapping (e.g., trypsin or LYS-C) analysis; assessing the biological activity or antigen binding function of the antibody; and so on. Instability can lead to aggregation, deamidation (e.g., Asn deamidation), oxidation (e.g., Met oxidation), isomerization (e.g., Asp isomerization), cleavage/hydrolysis/fragmentation (e.g., hinge region fragmentation), succinimide formation, unpaired cysteines(s), N-terminal extension, C-terminal processing, differences in glycosylation, and the like. Various techniques available to the skilled artisan can be used to assess biological activity or antigen binding function.
As mentioned above, freezing of the formulation is particularly contemplated. Thus, the formulations can be tested for stability after freezing and thawing.
Accordingly, the invention also provides a method of preparing a pharmaceutical formulation comprising preparing a formulation as described herein, and assessing the physical stability, chemical stability, or biological activity of the monoclonal antibody in the formulation.
In a preferred embodiment, the formulation is provided in a preferably aqueous form in a vial having a cap capable of being pierced by a syringe. The vial is desirably stored at about 2-8 ℃ until it is administered to a subject in need thereof. The vial may be, for example, a 20cc vial (e.g., for a 420mg dose) or a 50cc vial (e.g., for a 1050mg dose). For DR5 antibodies, such as Apomab, the formulation can be provided in a 5cc glass vial (e.g., 5.5ml full).
In another embodiment, the formulation is provided in a stainless steel can. The formulation in the stainless steel can is optionally frozen and not lyophilized.
One or more other pharmaceutically acceptable carriers, excipients or stabilizers may be included in the formulation, such as those described in Remington's Pharmaceutical Sciences 16th edition, Osol, a.ed. (1980), provided that they do not adversely affect the desired properties of the formulation. Acceptable carriers, excipients, or stabilizers are non-toxic to recipients at the dosages and concentrations employed, and include: other buffer solutions; a co-solvent; antioxidants include ascorbic acid and methionine; chelating agents such as EDTA; metal complexes (e.g., Zn-protein complexes); biodegradable polymers such as polyesters; a preservative; and/or salt-forming counterions such as sodium.
Treatment with antibody formulations
In one embodiment, the present invention provides a method of treating a disease or disorder in a subject, comprising administering to the subject an effective amount of a formulation described herein to treat the disease or disorder.
When the antibody in the formulation binds to HER2, it is preferably used for the treatment of cancer. The cancer will typically comprise HER 2-expressing cells, thereby enabling the HER2 antibodies herein to bind to cancer cells. Thus, in this embodiment the invention relates to a method of treating a HER2 expressing cancer in a subject comprising administering to the subject an effective amount of a HER2 antibody pharmaceutical formulation to treat the cancer. Various cancers that can be treated with the composition are listed in the definition section above.
It is also contemplated that the HER2 antibody formulation may be used in the treatment and treatment of non-malignant diseases or disorders, including autoimmune diseases (e.g. psoriasis); endometriosis; scleroderma; restenosis; polyps such as colon polyps, nasal polyps or gastrointestinal polyps; fibroadenoma; respiratory tract diseases (see definition above); cholecystitis (cholecystitis); neurofibromatosis; polycystic kidney disease; inflammatory diseases; skin diseases including psoriasis and dermatitis; vascular disease (see definition above); disorders involving abnormal proliferation of vascular epithelial cells; gastrointestinal ulcers; menetrier's disease, secretory adenoma or protein loss syndrome; renal disease; angiogenic diseases; eye diseases such as age-related macular degeneration, ocular pseudohistoplasmosis syndrome, retinal neovascularization due to proliferative diabetic retinopathy, retinal angiogenesis, diabetic retinopathy, or age-related macular degeneration; bone-related pathologies such as osteoarthritis, osteomalacia and osteoporosis; injury following a cerebral ischemic event; fibrotic or edematous (edemia) diseases such as cirrhosis of the liver, pulmonary fibrosis, carpoidosis, thyroiditis, systemic hyperviscosity syndrome, Osler Weber-Rendu disease, chronic occlusive lung disease, or edema following burns, trauma, radiation, stroke, hypoxia or ischemia; skin allergic reactions; diabetic retinopathy and diabetic nephropathy; Guillain-Barre syndrome; graft versus host disease or transplant rejection; paget's disease; bone or arthritis; photoaging (e.g., caused by UV radiation to human skin); benign prostatic hyperplasia; infection by certain microorganisms, including microbial pathogens selected from the group consisting of adenovirus, hantavirus, Borrelia burgdorferi (Borrelia burgdorferi), Yersinia spp (Yersinia spp.) and Bordetella pertussis (Bordetella pertussis); thrombosis caused by platelet aggregation; reproductive diseases such as endometriosis, ovarian hyperstimulation syndrome, preeclampsia, dysfunctional uterine bleeding, or menorrhagia; synovitis; atheroma (atherorma); acute and chronic kidney disease (including proliferative glomerulonephritis and diabetes-induced nephropathy); eczema; hypertrophic scarring; endotoxic shock and fungal infections; familial adenomatous polyposis; neurodegenerative diseases (e.g., alzheimer's disease, aids-related dementia, parkinsonism tremor, amyotrophic lateral sclerosis, retinitis pigmentosa, spinal muscular atrophy (spinal muscular atrophy), and cerebellar degeneration); myelodysplastic syndrome; aplastic anemia; ischemic injury; fibrosis of the lung, kidney or liver; t cell mediated allergic diseases; hypertrophic pyloric stenosis in infants; urinary disorder syndrome; psoriatic arthritis; and hashimoto's thyroiditis. Preferred non-malignant indications for treatment herein include psoriasis, endometriosis, scleroderma, vascular diseases (e.g. restenosis, atherosclerosis, coronary artery disease, or hypertension), colonic polyps, fibroadenomas or respiratory diseases (e.g. asthma, chronic bronchitis, bronchiectasis or cystic fibrosis).
Where the antibody in the formulation binds a B cell surface marker such as CD20 or BR3, the formulation may be used to treat a B cell malignancy, such as NHL or CLL, an autoimmune disease, transplant rejection, or suppress an immune response to a foreign antigen, such as an antibody, toxin, gene therapy viral vector, graft, infectious agent, or alloantigen (see WO 01/03734, Grillo-Lopez et al).
When the antibody in the formulation is an IgE antibody, it may be used to treat IgE-mediated disorders (USSN 2004/0197324a1, Liu and Shire), such as allergic asthma, allergic rhinitis, atopic (atopic) dermatitis, allergic gastrointestinal disease (allergic gastroenteropathy), allergy, eczema, urticaria, allergic bronchopulmonary aspergillosis (bronchus aspergillosis), parasitic diseases, hyper- (hyper) -IgE condensation syndrome, ataxia-telangiectasia (ataxia), weio-Aldrich syndrome, thymic lymphodysplasia (thymic lymphoplasia), myeloma IgE, and graft-versus-host reactions.
Antibodies that bind to receptors in the TNF superfamily (e.g., bind to DR5), or antibodies that bind to VEGF (or its receptor), may be used to treat cancer, various forms of which are described in the definition section above. Preferably, the cancer treated by the DR5 antibody preparation is a solid tumor or NHL.
When the indication is cancer, the patient may be treated with a combination of the antibody preparation and a chemotherapeutic agent. Combination administration includes co-administration or simultaneous administration using separate formulations or a single pharmaceutical formulation, and sequential administration in either order, wherein two (or all) active agents exert their biological activities simultaneously over a period of time. Thus, the chemotherapeutic agent may be administered before or after administration of the composition. In this embodiment, the time between at least one administration of the chemotherapeutic agent and at least one administration of the composition is preferably about 1 month or less, most preferably about 2 weeks or less. Alternatively, the chemotherapeutic agent and the composition are administered to the patient simultaneously in a single formulation or separate formulations.
Treatment with the formulation will result in an improvement in the signs or symptoms of the cancer or disease. For example, where the disease being treated is cancer, such treatment may result in an improvement in survival (overall survival and/or progression-free survival) and/or may result in a targeted clinical response (partial or complete). In addition, treatment with a combination of chemotherapeutic agents and antibody preparations may deliver synergistic or greater than additive therapeutic benefits to the patient.
Preferably, the antibody in the administered formulation is a naked antibody. However, the administered antibody may be conjugated to a cytotoxic agent. Preferably, the immunoconjugate and/or antigen to which it is bound is/are internalized by the cell, resulting in increased therapeutic efficacy of the immunoconjugate in killing the cancer cell to which it binds. In preferred embodiments, the cytotoxic agent targets or interferes with nucleic acids in cancer cells. Examples of such cytotoxic agents include maytansinoids (maytansinoids), calicheamicins (calicheamicins), ribonucleases and DNA endonucleases.
The formulations are administered to a human patient according to known methods, such as intravenous administration, e.g., as a bolus, or by continuous infusion over a period of time, by intramuscular, intraperitoneal, intracerobrospinal, subcutaneous, intraarticular, intrasynovial, intrathecal, oral, topical, or inhalation routes. Preferably, the antibody composition is administered intravenously, intramuscularly or subcutaneously, most preferably intravenously.
For subcutaneous delivery, the delivery may be by syringe; injection devices (e.g., injection-EASETM and genjectm devices); injection pens (e.g., genpen); needleless devices (e.g., MEDIJECTORTM and BIOJECTORTM); or a subcutaneous patch delivery system.
For the prevention and treatment of disease, the appropriate dosage of antibody will depend on the type of disease to be treated, as defined above, the severity and course of the disease, whether the antibody is administered for prophylactic or therapeutic purposes, previous therapy, the patient's clinical history and response to the antibody, and the discretion of the attending physician. The antibody is administered to the patient at one time or over a series of treatments. Depending on the type and severity of the disease, approximately 1. mu.g/kg to 50mg/kg (e.g. 0.1-20mg/kg) of HER2 or DR5 antibody is the initial candidate dose for administration to a patient, which may be by one or more separate administrations, or by continuous perfusion. The dosage of antibody is generally from about 0.05mg/kg to about 10 mg/kg. If a chemotherapeutic agent is administered, it is generally administered at its known dose, or optionally in a reduced amount, because administration of the chemotherapeutic agent can result in combined or side effects of the drug. The preparation and dosage regimen for such chemotherapeutic agents can be used according to manufacturer's instructions or as determined empirically by a physician. The preparation and dosage regimen for such chemotherapies is also described in Chemotherapy Service ed, m.c. perry, Williams & Wilkins, Baltimore, MD (1992).
Other therapeutic regimens may be combined with the antibody, including, but not limited to: a second (third, fourth, etc.) chemotherapeutic agent (i.e., a mixture of different chemotherapeutic agents); another monoclonal antibody; a growth inhibitor; a cytotoxic agent; a chemotherapeutic agent; an EGFR-targeting drug; tyrosine kinase inhibitors; an anti-angiogenic agent; and/or a cytokine; and so on.
In addition to the above treatment regimens, the patient may also undergo surgical removal of cancer cells and/or radiation therapy.

In another embodiment of the invention, an article of manufacture comprising a pharmaceutical formulation of the invention is provided, together with instructions for use thereof. The article of manufacture includes a container. Suitable containers include, for example, bottles, vials (e.g., dual chamber vials), syringes (e.g., dual chamber syringes), and test tubes. The container may be formed from a number of materials such as glass or plastic. The container holds the formulation and indicia on or associated with the container may indicate instructions for use. The container containing the formulation may be a multi-purpose vial which allows repeated administration of the reconstituted formulation (e.g. 2-6 administrations). The article of manufacture may further comprise materials required from other commercial and user standpoints, including other buffers, diluents, filters, needles, syringes, and package inserts with instructions for use as described in the preceding section.
The present invention will be more fully understood by reference to the following examples. However, they should not be construed as limiting the scope of the invention. All documents and patents cited are incorporated herein by reference.
Examples
Stable liquid Pertuzumab formulation
These examples describe the development and stability testing of stable liquid formulations comprising Pertuzumab at a protein concentration of about 10mg/mL to 180 mg/mL. The selected formulations have low turbidity and are physically and chemically stable. Chloride ions are removed from the formulation to reduce the risk of erosion. The formulation is isotonic and suitable for subcutaneous or intramuscular delivery. Formation of insoluble aggregates following shaking (aggregation stress) was prevented using histidine-acetate and sucrose formulations, without the need to include polysorbate 20.
Analytical method
Color, appearance and clarity (CAC)
The color, appearance and clarity of the samples were determined by visual inspection of the vials against white and black backgrounds at room temperature under white fluorescence.
UV concentration measurement
The liquid product is first diluted with formulation buffer so that the Amax is 0.5-1.0 absorbance units near 278 nm. The UV absorbance of the diluted samples was measured on an HP8453 spectrophotometer in a 1cm diameter quartz cup. The absorbance at 278nm and 320nm was measured. The absorbance from 320nm was used to correct for background light scattering due to larger aggregates, bubbles and particles. The measurements were zeroed relative to the formulation buffer. Protein concentration was determined using absorbance of 1.50(mg/mL) -1 cm-1.
pH measurement
Utilizing RADIOMETER COPENHAGEN PHM82TMThe pH meter measures pH at room temperature. The detector used was a glass/reference electrode (Sigma, Cat # E-5759) in combination with a radiometer connector. The pH meter was calibrated using standard solutions of pH4.01 and pH7.00(EM Science).
Ion exchange chromatography (IEX)
The change in charge variable was measured using cation exchange chromatography. This assay was performed in HP1100TMDIONEX PROPAC WCX-10 on HPLC systemTMAnd (3) a column. The sample was diluted to 1mg/mL with mobile phase A containing 20mM MES pH 6.0. 50mL of the diluted sample was then loaded onto a column maintained at ambient temperature. The peak was eluted with a shallow NaCl gradient using mobile phase B containing 20mM MES, 250mM NaCl, pH 6.0. The eluate was monitored at 280 nm.Using HPCHEMStationTMThe software (Rev a08.03) analyzed the data.
Capillary Zone Electrophoresis (CZE)
The purity of Fab and F (ab') 2 fragments was determined by CZE. The assay was performed in BIORADBIOFOCUSTM3000TMBIOCAP XL on capillary electrophoresis systemTMCapillary, 50 μm i.d., 44.6cm full length, and run at 40cm distance from the detector.
Size Exclusion Chromatography (SEC)

Example 12
Apoptosis is mediated by both intrinsic and extrinsic pathways. Chemotherapy can trigger cellular damage and may promote apoptosis by responding to the intrinsic pathways of cellular damage. However, cancer cells often develop resistance to chemotherapy through mutations in the p53 tumor suppressor gene (Ashkenazi A. targeting Death and decoy Receptors of the tumor-Necrosis Factor Superfamily. Nature Reviews 2: 420-430 (2002)). Death receptors located on the cell surface, such as DR4 and DR5, promote apoptosis through extrinsic pathways that do not include p 53. Agonistic molecules, such as Apo2L, bind to the DR4 and DR5 receptors and activate caspases (caspases) 8 and 10 through the Fas-associated death domain. Caspases 8 and 10 subsequently activate caspases 3, 6, and 7 to induce apoptosis. The molecular signaling of death receptors on tumor cells is therapeutically effective for eliminating cancer cells resistant to traditional therapies and molecules like Apo2L, which are currently being evaluated clinically.
"Apomab" is a full-length CHO-derived humanized IgG1 constructed with a lambda light chain. It is an agonist antibody against DR5, which has been shown to induce apoptosis in various cancer cell lines. Preclinical studies using murine tumor implantation models have shown that Apomab has a similar or enhanced tumor reduction compared to Apo 2L. Apomab is being evaluated as an anti-cancer agent for use in advanced solid tumors and non-Hodgkin's lymphoma (NHL). The heavy and light chain amino acid sequences of Apomab used in these experiments are shown in fig. 27 and 28.
Preparation of antibody formulations
Recombinantly produced Apomab has a very dilute protein concentration and a high pH. The material was concentrated to about 20mg/mL and subjected to Millipore Labscale cut flow filtration (TFF) using Millipore Labscale cut flow filtration (TFF) system to form a Millipore PelliconTMXL, PLCGC10, 50cm membrane exchanged into 20mM sodium acetate, pH5.0 buffer. Use of trehalose-free and TWEENSodium acetate, histidine acetate, and sodium phosphate Apomab samples were formulated into various buffer systems, pH from 4.0 to 7.0, and dialyzed against a 10,000Da molecular weight exclusion membrane (Pierce, Inc). In the final dialysis 240mM trehalose was added. After dialysis, 0.02% TWEEN20TM was added to the formulation and the sample was filtered with a 0.22 μm filter (Millipore, Inc.). A volume of 0.5mL Apomab was loaded into a sterile 3cc glass vial (form Vitrum, Inc.) and closed with a 13mm stopper (Daikyo, Inc). Protein stability was assessed by storage at-70 ℃, 5 ℃, 30 ℃, and 40 ℃ for 3 months.
Stability of Apomab formulations
For the drug product stability test, the Apomab formulation was charged to 5cc FORMAIn a glass bottle. Vials were filled with 5.5mL of the formulated antibody, using 20mmThe stopper was closed and stored in a head-up position at-70 ℃, 5 ℃, 30 ℃, and 40 ℃.
For drug substance stability testing, the Apomab formulation was sterile filtered through a 0.22 μm filter and 10mL were loaded into a autoclaved 20cc316L stainless steel canister. The small can is placed vertically at-20 deg.C and 5 deg.C. Aliquots of 1mL were aseptically removed from the canister at specified time intervals to assess protein quality. The control vial was a 1mL aliquot stored in a 3cc glass vial at-20 ℃.
Color, appearance and clarity
The clarity, appearance and color of the samples were visually assessed using a white and black background stage under room temperature white fluorescence. To analyze the drug substance, the canister sample was transferred to a 3cc glass vial for examination.
pH
For measuring the THERMO ORION SURE-FLOW ROSS of a bufferTMSemi-micro pH electrode or THERMO ORION GLS for measuring protein pH of screening sampleTMA Beckman microelectrode for toxicologically stable samples combined with a micro-pH electrode measures pH at room temperature. METERLAB was calibrated daily with buffer standards (EM Science) at pH7 and pH4 TMpHM240 pH/Ionic apparatus (Radiometer Analytical).
Concentration of
The protein concentration was measured by ultraviolet absorption spectroscopy using an aglent 8453TM spectrophotometer. The samples were diluted with the appropriate blank formulation buffer to give an absorbance from 0.5 to 1.0. The instrument was zeroed with the dilution solution and the spectrum was scanned from 240 to 500 nm. The absorbance value at 320nm was subtracted from the absorbance at 279nm to correct for offset and light scattering. The protein concentration was calculated by the following equation:
concentration (mg/mL) ═ concentration(A279-A320) X dilution factor
Absorption coefficient cm-1(mg/mL)-1
The sequence-based absorption coefficient was initially determined to be 1.32cm-1(mg/mL)-1And this value was used in a pH screening study. The latter value, determined by amino acid analysis and protein hydrolysis, was 1.7cm-1(mg/mL)-1And this value was used in toxicology studiesStability analysis of Apomab (a).
Ion exchange chromatography
Ion exchange chromatography was performed on a 1100 series HPLC (Agilent Technologies, Inc.) equipped with a diode array detector. In PROPAC WCX-10TMChromatography was performed on a (Dionex) column (4X250mm) at a flow rate of 0.5mL/min, column temperature 40 ℃. The mobile phase A was 25mM sodium phosphate, pH 6.5. Mobile phase B was 100mM sodium chloride in the same buffer as mobile phase a. The column was equilibrated with 100% mobile phase a. For the pH-screened samples, an amount of 20mg of Apomab was applied to the column and the absorbance was monitored at 214 nm. The protein was eluted from the column with the following gradient:

size exclusion chromatography
Size exclusion chromatography was performed on a 1100 series HPLC (Agilent Technologies, Inc.) equipped with a diode array detector. Apomab in an amount of 50. mu.g was applied to a TSK gel 3000SWXLTM (7.8X300mm) column and run at a flow rate of 0.9mL/min for 20 minutes for the pH screening sample and 0.5mL/min for 30 minutes for the toxicologically stable sample with 0.20M potassium phosphate, 0.25M potassium chloride, pH6.2 as the mobile phase. The absorbance was monitored at 280 nm.
Efficiency of
The purpose of the potency bioassay was to use ALAMARBLUETMThe ability of Apomab to kill Colo205 cells was measured. Colo205 is a colon cancer cell line that expresses DR5 and DR4 death receptors. Such assays include fluorescent/colorimetric growth indicators based on the detection of metabolic activity. ALAMARBLUETMIs a redox dye that is blue and non-fluorescent in the oxidized state. Intracellular metabolic reduction converts it to a red color, which is also fluorescent. The color and fluorescence change is proportional to the metabolic activity and number of living cells. The signal decreases when the cell dies. Apomab was diluted in culture medium with anti-Fc, and Colo205 cells were subsequently added to the Apomab sample and incubated at 37 ℃ for 48 hours. Adding ALAMARBLUE for the last 2-3 hr TM. Plates were read at 530nm excitation and 590nm emission to obtain Relative Fluorescence Units (RFU). By KALEIDAGRAPHTMThe data is analyzed. A dilution curve of killing was generated.
Results
Formulation pH screening study
The effect of pH on antibody stability was studied using Apomab produced by a stable, non-proliferating cell line. For this assay, Apomab was formulated at 20mg/mL antibody in 20mM sodium acetate buffer, pH4.0, 4.5, 5.0, 5.5; 20mM histidine acetate buffer, pH6.0 and 6.5; and 20mM sodium phosphate bufferpH 7.0. All formulations contained 240mM trehalose and 0.02% TWEENThe formulations were stored at-70 ℃, 5 ℃, 30 ℃, and 40 ℃ for up to 3 months and protein stability was determined by various analytical assays including CAC, pH, concentration, SEC, and IEC. No significant change in CAC, pH or protein concentration was observed during sample storage.
Analysis of the samples by SEC showed no significant change during storage at 5 ℃ and-70 ℃. However, degradation was observed during storage at 30 ℃ and 40 ℃, which was indicative of the formation of antibody fragments and soluble aggregates (fig. 20). To compare the formulations, the kinetics of the antibody monomers during storage were monitored and the first order rate constants were calculated. The pH rate curve obtained for antibody monomer loss is shown in figure 21. Optimal conditions for antibody monomer stability were obtained by formulation in histidine acetate buffer at ph 6.0.
Apomab charge heterogeneity was monitored by IEC. No significant change in IEC curve occurred during storage at 5 ℃ and-70 ℃. However, degradation was observed, which appeared to form acidic or basic variants depending on the formulation (fig. 22). In general, the base-enhancing variants form at lower formulation pH and the more acidic variants form at higher formulation pH. To compare the formulations, the kinetics of the IEC main peak were monitored during storage and the first order rate constant was calculated. The pH rate curve obtained for IEC main peak loss is shown in figure 23. The rate constants observed by IEC were approximately 10 times higher than those observed by SEC (figure 21). Therefore, the loss of the IEC main peak is a preliminary degradation of the antibody, which will ultimately limit the shelf life of the product. In addition, it was observed by SEC that the best antibody stability to stabilize the IEC main peak was obtained by formulating in histidine acetate buffer at ph 6.0.
Following analysis of the pH screening data described above, Apomab formulations were selected containing 20mg/mL antibody in 20mM histidine acetate, 240mM trehalose, 0.02% polysorbate 20, pH 6.0. For pharmaceutical productsThe medicine bottle is prepared by packing in 5cc of formula VITRUM TM5.5mL in a vial with 20mM DAIKYOTMWest plug. Apomab was stored in stainless steel tanks.
Stability of Apomab drug product was evaluated in the above 5cc glass vial configuration. Vials were stored at-70 ℃ (control), 5 ℃, 30 ℃, and 40 ℃. Samples were withdrawn at specific time intervals and analyzed by the following assay: color, appearance, clarity (CAC), pH, protein concentration, SEC, IEC, and potency. The results of these measurements for the samples stored at-70 ℃ and 5 ℃ are shown in Table 6, while the results for the samples stored at 30 ℃ and 40 ℃ are shown in Table 7.

No change in protein quality was observed after 12 months of storage at-70 ℃ and 5 ℃. For example, the pH was maintained at 6.0 ± 0.3, Apomab was present as a clear and colorless liquid, the protein concentration was maintained at 20.0 ± 2.0mg/mL, and% monomer was unchanged. In addition, the% IEC main peak was not significantly changed and the% specific activity determined by cell killing potency assay was within the accuracy of the determination of 60% to 140% specific activity. The results show that Apomab stored in a 5cc glass vial is stable at 5 ℃ for at least 12 months.
Table 7 shows that the change in protein mass occurs at 30 ℃ and 40 ℃. SEC showed a decrease in% monomer with an increase in predominantly fragmented material. Aggregates increased as with higher temperatures, but at a much lower rate. However, aggregates increased significantly after 6 months at 40 ℃. The IEC% main peak was reduced with a corresponding increase in acidic variants. The alkaline peak decreased slightly after 40 ℃, 2 months and after 9 months at 30 ℃. After six months of storage at 40 ℃, a decrease occurs to the point where the IEC main peak can no longer integrate. Cell killing bioassay shows that longer storage times at higher temperatures result in a loss of% specific activity. Protein concentration and pH were unchanged. The solution turned pale yellow after 9 months at 40 ℃, 3 and 30 ℃ and yellow after 9 months at 40 ℃.

No significant change in the chemical properties of the protein was observed after freezing at-20 ℃ for at least 15 hours and three thawing at ambient temperature. For example, Apomab appears as a clear and colorless liquid, with the pH maintained at 6.0 ± 0.3, while the SEC monomer peak percentage is unchanged.
Apomab stability in stainless steel containers was evaluated at-20 ℃ and 5 ℃ (Table 9).
Samples were drawn from the canister at specific intervals under sterile conditions and analyzed.
Apomab showed no change in protein mass with respect to pH, CAC, protein concentration and% main peak obtained by IEC, but lost 0.1% of monomer every 3 months as seen by SEC. A decrease in efficacy was observed during storage at 5 ℃ for 3 months. However, the efficacy of the samples increased again at the 6 month and 9 month time points. Therefore, the difference in potency at the 3 month time point was attributed to assay bias. Apomab was seen to show no change in protein mass and no significant change in potency by pH, CAC, protein concentration,% monomer by SEC,% main peak by IEC. The stability data show that Apomab is stable at-20 ℃ for at least 1 year and at 5 ℃ for three months.
Conclusion
Formulation screening studies were performed to select Apomab formulations. pH screens covering a pH range of 4.0 to 7.0 using sodium acetate, histidine acetate, and sodium phosphate, together with 240mM trehalose dihydrate and 0.02% polysorbate 20 as buffers, showed that Apomab was most stable in solution at pH 6.0. Therefore, a formulation consisting of 20mM histidine acetate, 240mM trehalose, 0.02% polysorbate 2, ph6.0 was developed and proved to be stable by experiments. With this formulation, Apomab was shown to be stable at 5 ℃ for at least 12 months. Additionally, Apomab was shown to be stable at-20 ℃ for at least 12 months and at 5 ℃ for three months when stored in 316L stainless steel containers. Apomab was also shown to be stable when subjected to up to 3 freeze-thaw cycles.
