Title:Methods of treating anemia using anti-IL-6 antibodies
Abstract: The invention provides methods of treating anemia in patients in need thereof, particularly in patients having anemia associated with chronic and/or inflammatory conditions such as cancers and arthritic conditions by administering antibodies or antibody fragments that bind IL-6. The treatment methods result in increased hemoglobin.

Application Number:12/624,816
Patent Claims:1. A method of treating anemia in a patient having a disorder involving elevated interleukin-6 (IL-6), comprising administering to the patient an anti-IL-6 antibody or antibody fragment, said antibody or antibody fragment comprising the variable light complementarity regions (CDR's) of SEQ ID NO:4, 5 and 6 and the variable heavy complementarity regions (CDR's) of SEQ ID NO:7, 8 or 120 and 9.

2.

5. The method of claim 1, wherein the anti-IL-6 antibody or antibody fragment is aglycosylated and/or contains an Fc region that has been modified to alter effector function, half-life, proteolysis, and/or glycosylation.

6. The method of claim 1, wherein the anti-IL-6 antibody or antibody fragment is a human, humanized, single chain or chimeric antibody.

7.

8. The method of claim 3 wherein said antibody further comprises the heavy constant and light constant sequences in SEQ ID NO:588 and SEQ ID NO:586.

9. The method of claim 1, wherein the patient's serum hemoglobin levels increase after said anti-IL-6 antibody or antibody fragment administration.

10. The method of claim 1, wherein the patient has been diagnosed with cancer.

11. The method of claim 1, wherein said antibody comprises a human F.sub.c derived from IgG1, IgG2, IgG3, or IgG4.

12. The method of claim 1, wherein the anti-IL-6 antibody or antibody fragment has an elimination half-life selected from (i) at least about 22 days, (ii) at least about 25 days and (iii) at least about 30 days.

13. The method of claim 1, wherein the anti-IL-6 antibody or antibody fragment is co-administered with another therapeutic agent.

14. The method of claim 13, wherein the other therapeutic agent is selected from VEGF antagonists, EGFR antagonists, platins, taxols, irinotecan, 5-fluorouracil, gemcytabine, leucovorine, steroids, cyclophosphamide, melphalan, vinca alkaloids, vinblastine, mustines, tyrosine kinase inhibitors, radiotherapy, sex hormone antagonists, selective androgen receptor modulators, selective estrogen receptor modulators, PDGF antagonists, TNF antagonists, IL-1 antagonists, interleukins, IL-12R antagonists, Toxin conjugated monoclonal antibodies, tumor antigen specific monoclonal antibodies, Erbitux.TM., Avastin.TM., Pertuzumab, anti-CD20 antibodies, ocrelizumab, ofatumumab, DXL625, Herceptin.RTM., or any combination thereof; or comprises an inhibitor of JAK1, JAK2, JAK3, or SYK.

15. The method of claim 1 wherein the disease or condition associated with anemia is a cancer; or rheumatoid arthritis.

16. The method of claim 1, further comprising administration of an antagonist of a cachexia-associated factor, weakness-associated factor, fatigue-associated factor, and/or fever-associated factor.

17. The method of claim 16, wherein the cachexia-associated factor, weakness-associated factor, fatigue-associated factor, and/or fever-associated factor is selected from tumor necrosis factor-alpha, Interferon gamma, Interleukin 1 alpha, Interleukin 1 beta, Interleukin 6, proteolysis inducing factor, leukemia-inhibitory factor, or any combination thereof or is selected from cannabis, dronabinol (Marinol.TM.), nabilone (Cesamet), cannabidiol, cannabichromene, tetrahydrocannabinol, Sativex, megestrol acetate, or any combination thereof.
