Definitions

  • the invention relates generally to compounds with anti-cancer activity and more specifically to antibodies conjugated with chemotherapeutic maytansinoid drugs or toxins.
  • the invention also relates to methods of using antibody-drug conjugate compounds for in vitro, in situ, and in vivo diagnosis or treatment of mammalian cells, or associated pathological conditions.
  • Antibody therapy has been established for the targeted treatment of patients with cancer, immunological and angiogenic disorders.
  • ADC antibody-drug conjugates
  • cytotoxic or cytostatic agents i.e. drugs to kill or inhibit tumor cells in the treatment of cancer
  • cytotoxic or cytostatic agents i.e. drugs to kill or inhibit tumor cells in the treatment of cancer
  • Efforts to design and refine ADC have focused on the selectivity of monoclonal antibodies (mAbs) as well as drug-linking and drug-releasing properties. Both polyclonal antibodies and monoclonal antibodies have been reported as useful in these strategies (Rowland et al., (1986) Cancer Immunol. Immunother. 21:183-87). Drugs used in these methods include daunomycin, doxorubicin, methotrexate, mitomycin, neocarzinostatin (Takahashi et al (1988) Cancer 61:881-888) and vindesine (Rowland et al., (1986) supra).
  • Toxins used in antibody-toxin conjugates include bacterial toxins such as diphtheria toxin, plant toxins such as ricin (U.S. Pat. No. 4,753,894; U.S. Pat. No. 5,629,197; U.S. Pat. No. 4,958,009; U.S. Pat. No. 4,956,453), small molecule toxins such as geldanamycin (Mandler et al (2000) J. of the Nat. Cancer Inst. 92(19):1573-1581; Mandler et al (2000) Bioorganic & Med. Chem. Letters 10: 1025-1028; Mandler et al (2002) Bioconjugate Chem.

  • MYLOTARGTM (gemtuzumab ozogamicin, Wyeth Pharmaceuticals), an antibody-drug conjugate composed of a hu CD33 antibody linked to calicheamicin, was approved in 2000 for the treatment of acute myeloid leukemia by injection (Drugs of the Future (2000) 25(7):686; U.S. Pat. No. 4,970,198; U.S. Pat. No. 5,079,233; U.S. Pat. No. 5,585,089; U.S. Pat. No. 5,606,040; U.S. Pat. No. 5,693,762; U.S. Pat. No. 5,739,116; U.S. Pat. No.
  • Cantuzumab mertansine (Immunogen, Inc.), an antibody-drug conjugate composed of the huC242 antibody linked via the disulfide linker SPP to the maytansinoid drug moiety, DM1 (Xie et al (2004) J. of Pharm. and Exp. Ther. 308(3):1073-1082; Tolcher et al (2003) J. Clin. Oncology 21(2):211-222; U.S. Pat. No. 5,208,020), underwent Phase I trials for the treatment of cancers that express CanAg, such as colon, pancreatic, gastric, and others.
  • CanAg such as colon, pancreatic, gastric, and others.
  • MLN-2704 (Millennium Pharm., BZL Biologics, Immunogen Inc.) is an antibody-drug conjugate composed of the anti-prostate specific membrane antigen (PSMA) monoclonal antibody linked to the maytansinoid drug moiety, DM1, under development for the potential treatment of prostate tumors.
  • PSMA anti-prostate specific membrane antigen
  • DM1 maytansinoid drug moiety
  • SMCC non-disulfide linker
  • TA.1 mouse murine monoclonal antibody
  • SMCC linker was considered therein to be “noncleavable” (also, see: U.S. Pat. No. 4,981,979).
  • HERCEPTIN® tacuzumab linked by SMCC to DM1 has been reported (WO 2005/037992).
  • tumor-associated polypeptides that are specifically expressed on the surface of one or more particular type(s) of cancer cell as compared to on one or more normal non-cancerous cell(s). Often, such tumor-associated polypeptides are more abundantly expressed on the surface of the cancer cells as compared to on the surface of the non-cancerous cells.
  • TAA tumor-associated antigens
  • HERCEPTIN® tacuzumab
  • HER2 ErbB2
  • Trastuzumab is an IgG1 kappa antibody that contains human framework regions with the complementarity-determining regions of a murine antibody (4D5) that binds to HER2. Trastuzumab binds to the HER2 antigen and thus inhibits the growth of cancerous cells. Because trastuzumab is a humanized antibody, it minimizes any HAMA response in patients. The humanized antibody against HER2 is produced by a mammalian cell (Chinese Hamster Ovary, CHO) suspension culture.
  • the HER2 (or c-erbB2) proto-oncogene encodes a transmembrane receptor protein of 185 kDa, which is structurally related to the epidermal growth factor receptor.
  • HER2 protein overexpression is observed in 25%-30% of primary breast cancers and can be determined using an immunohistochemistry based assessment of fixed tumor blocks (Press M F, et al (1993) Cancer Res 53:4960-70.
  • Trastuzumab has been shown, in both in vitro assays and in animals, to inhibit the proliferation of human tumor cells that overexpress HER2 (Hudziak R M, et al (1989) Mol Cell Biol 9:1165-72; Lewis G D, et al (1993) Cancer Immunol Immunother; 37:255-63; Baselga J, et al (1998) Cancer Res. 58:2825-2831).
  • Trastuzumab is a mediator of antibody-dependent cellular cytotoxicity, ADCC (Hotaling T E, et al (1996) [abstract]. Proc. Annual Meeting Am Assoc Cancer Res; 37:471; Pegram M D, et al (1997) [abstract].
  • HERCEPTIN® is clinically active in patients with ErbB2-overexpressing metastatic breast cancers that have received extensive prior anti-cancer therapy (Baselga et al, (1996) J. Clin. Oncol. 14:737-744).
  • HERCEPTIN is a breakthrough in treating patients with ErbB2-overexpressing breast cancers that have received extensive prior anti-cancer therapy, the majority of the patients in this population fail to respond or respond only poorly to HERCEPTIN treatment. Therefore, there is a significant clinical need for developing further HER2-directed cancer therapies for those patients with HER2-overexpressing tumors or other diseases associated with HER2 expression that do not respond, or respond poorly, to HERCEPTIN treatment. In addition to HER2, there is an opportunity to exploit other tumor-associated antigens with targeted therapies.
  • the present invention provides novel compounds with biological activity against cancer cells.
  • the compounds may inhibit tumor growth in mammals and may be useful for treating human cancer patients.
  • the present invention relates to the delivery, transport, accumulation or retention of therapeutic antibody-drug conjugate (ADC) compounds inside cells.
  • ADC therapeutic antibody-drug conjugate
  • the invention is more particularly related to attaining high concentrations of active metabolite molecules in cancer cells.
  • Intracellular targeting may be achieved by methods and compounds which allow accumulation or retention of biologically active agents inside cells. Such effective targeting may be applicable to a variety of therapeutic formulations and procedures.
  • antibody-drug conjugates with stable, non-disulfide linkers groups that attach a maytansinoid drug moiety to an antibody result in increased in vitro potency and in vivo efficacy.
  • the antibody-drug conjugates show the unexpected result of better safety in vivo relative to certain disulfide linker conjugates.
  • Antibody-drug conjugate (ADC) compounds comprise an antibody covalently attached by a linker to one or more maytansinoid drug moieties.
  • ADC may be represented by Formula I: Ab-(L-D) p I
  • a substantial amount of the drug moiety is not cleaved from the antibody until the antibody-drug conjugate enters a cell with a cell-surface receptor specific for the antibody of the antibody-drug conjugate, and the drug moiety is cleaved from the antibody when the antibody-drug conjugate does enter the cell.
  • the ADC specifically binds to a receptor encoded by an ErbB gene, such as EGFR, HER2, HER3 and HER4.
  • the ADC may specifically bind to the extracellular domain of the HER2 receptor.
  • the ADC may inhibit growth of tumor cells which overexpress HER2 receptor.

  • “Native antibodies” are usually heterotetrameric glycoproteins of about 150,000 daltons, composed of two identical light (L) chains and two identical heavy (H) chains. Each light chain is linked to a heavy chain by one covalent disulfide bond, while the number of disulfide linkages varies among the heavy chains of different immunoglobulin isotypes. Each heavy and light chain also has regularly spaced intrachain disulfide bridges. Each heavy chain has at one end a variable domain (VH) followed by a number of constant domains. Each light chain has a variable domain at one end (VL) and a constant domain at its other end. The constant domain of the light chain is aligned with the first constant domain of the heavy chain, and the light-chain variable domain is aligned with the variable domain of the heavy chain. Particular amino acid residues are believed to form an interface between the light chain and heavy chain variable domains.
  • variable refers to the fact that certain portions of the variable domains differ extensively in sequence among antibodies and are used in the binding and specificity of each particular antibody for its particular antigen. However, the variability is not evenly distributed throughout the variable domains of antibodies. It is concentrated in three segments called hypervariable regions both in the light chain and the heavy chain variable domains. The more highly conserved portions of variable domains are called the framework regions (FRs).
  • the variable domains of native heavy and light chains each comprise four FRs, largely adopting a ⁇ -sheet configuration, connected by three hypervariable regions, which form loops connecting, and in some cases forming part of, the ⁇ -sheet structure.
  • the hypervariable regions in each chain are held together in close proximity by the FRs and, with the hypervariable regions from the other chain, contribute to the formation of the antigen-binding site of antibodies (see Kabat et al (1991) Sequences of Proteins of Immunological Interest, 5th Ed. Public Health Service, National Institutes of Health, Bethesda, Md.).
  • the constant domains are not involved directly in binding an antibody to an antigen, but exhibit various effector functions, such as participation of the antibody in antibody dependent cellular cytotoxicity (ADCC).
  • hypervariable region when used herein refers to the amino acid residues of an antibody which are responsible for antigen-binding.
  • the hypervariable region generally comprises amino acid residues from a “complementarity determining region” or “CDR” (e.g., residues 24-34 (L1), 50-56 (L2) and 89-97 (L3) in the light chain variable domain and 31-35 (H1), 50-65 (H2) and 95-102 (H3) in the heavy chain variable domain; Kabat et al supra) and/or those residues from a “hypervariable loop” (e.g., residues 26-32 (L1), 50-52 (L2) and 91-96 (L3) in the light chain variable domain and 26-32 (H1), 53-55 (H2) and 96-101 (H3) in the heavy chain variable domain; Chothia and Lesk (1987) J.

  • “Framework Region” or “FR” residues are those variable domain residue
  • Papain digestion of antibodies produces two identical antigen-binding fragments, called “Fab” fragments, each with a single antigen-binding site, and a residual “Fc” fragment, whose name reflects its ability to crystallize readily. Pepsin treatment yields an F(ab′)2 fragment that has two antigen-binding sites and is still capable of cross-linking antigen.
  • “Fv” is the minimum antibody fragment which contains a complete antigen-recognition and antigen-binding site. This region consists of a dimer of one heavy chain and one light chain variable domain in tight, non-covalent association. It is in this configuration that the three hypervariable regions of each variable domain interact to define an antigen-binding site on the surface of the VH-VL dimer. Collectively, the six hypervariable regions confer antigen-binding specificity to the antibody. However, even a single variable domain (or half of an Fv comprising only three hypervariable regions specific for an antigen) has the ability to recognize and bind antigen, although at a lower affinity than the entire binding site.
