Anti-IL-6 antibodies, compositions, methods and uses
View Patent ↗The present invention relates to at least one novel chimeric, humanized or CDR-grafted anti-IL-6 antibodies derived from the murine CLB-8 antibody, including isolated nucleic acids that encode at least one such anti-IL-6 antibody, vectors, host cells, transgenic animals or plants, and methods of making and using thereof, including therapeutic compositions, methods and devices.
1. A method for inhibiting tumor growth in a cell, tissue, organ or animal, or inhibiting cancer cachexia in an animal, comprising contacting or administering to said cell, tissue, organ or animal a pharmaceutically effective amount of an IL-6 antibody or fragment thereof comprising a heavy chain variable region having the amino acid sequence of SEQ ID NO:7, a light chain variable region having the amino acid sequence of SEQ ID NO:8, and a constant region derived from one or more human antibodies.
2. A method according to claim 1 , wherein said tumor or cancer is at least one selected from leukemia, acute leukemia, acute lymphoblastic leukemia, B-cell, T-cell or FAB acute lymphoblastic leukemia, acute myeloid leukemia, chronic myelocytic leukemia, chronic lymphocytic leukemia, hairy cell leukemia, myelodyplastic syndrome, a lymphoma, Hodgkin's disease, a malignant lymphoma, non-hodgkin's lymphoma, Burkitt's lymphoma, multiple myeloma, Kaposi's sarcoma, colorectal carcinoma, pancreatic carcinoma, renal cell carcinoma, prostatic cell carcinoma, nasopharyngeal carcinoma, malignant histiocytosis, paraneoplastic syndrome/hypercalcemia of malignancy, solid tumors, adenocarcinomas, sarcomas, and malignant melanoma.
3. A method according to claim 1 wherein said effective amount is 0.01-100 mg/kilogram of said cells, tissue, organ or animal.
4. A method according to claim 1 , further comprising administering, prior, concurrently or after said contacting or administering, at least one composition comprising a therapeutically effective amount of at least one compound or protein selected from at least one of a TNF antagonist, an antirheumatic, a muscle relaxant, a narcotic, a non-steroid anti-inflammatory drug (NSAID), an analgesic, an anesthetic, a sedative, a local anethetic, a neuromuscular blocker, an antimicrobial, an antipsoriatic, a corticosteriod, an anabolic steroid, a diabetes related agent, a mineral, a nutritional, a thyroid agent, a vitamin, a calcium related hormone, an antidiarrheal, an antitussive, an antiemetic, an antiulcer, a laxative, an anticoagulant, an erythropieitin, a filgrastim, a sargramostim, an immunization, an immunoglobulin, an immunosuppressive, a growth hormone, a hormone replacement drug, an estrogen receptor modulator, a mydriatic, a cycloplegic, an alkylating agent, an antimetabolite, a mitotic inhibitor, a radiopharmaceutical, an antidepressant, antimanic agent, an antipsychotic, an anxiolytic, a hypnotic, a sympathomimetic, a stimulant, donepezil, tacrine, an asthma medication, a beta agonist, an inhaled steroid, a leukotriene inhibitor, a methylxanthine, a cromolyn, an epinephrine or analog, dornase alpha, a cytokine, a cytokine antagonist.
5. A method for inhibiting tumor growth in a cell, tissue, organ or animal, or inhibiting cancer cachexia in an animal comprising contacting or administering to said cell, tissue, organ or animal a pharmaceutically effective amount of an isolated antibody or antibody fragment that binds to human IL-6, comprising the heavy chain and light chain complementarity determining regions (CDRs) having the amino acid sequences of SEQ ID NOS:1-6, and a constant region derived from one or more human antibodies.
