Method of treating rheumatoid arthritis with an anti-IL-6R antibody
The present invention provides methods of preventing or treating rheumatoid arthritis using a fully human antibody or antigen-binding fragment thereof that specifically binds human interleukin-6 receptor (hIL-6R). The methods of the present invention may include administration of a second therapeutic agent, such as one or more of a non-steroidal anti-inflammatory drug (NSAID), a glucocorticoid, a disease-modifying anti-rheumatic drug (DMARD), or a TNF-alpha antagonist, T-cell blocker, anti-CD20 antibody, an IL-1, JAK or IL-17 antagonist, or any combination thereof.
1. A method for treating rheumatoid arthritis (RA) in a subject, said method comprising administering to the subject a therapeutically effective amount of a human antibody or antigen-binding fragment thereof which specifically binds to human interleukin-6 (hIL-6R), wherein the human antibody or antigen-binding fragment comprises the complementarity determining region (CDR) sequences of a heavy chain variable region (HCVR) and light chain variable region (LCVR) pair (HCVR/LCVR) set forth in SEQ ID NO:19/27.
2. The method of claim 1 , wherein the antibody or antigen-binding fragment comprises a CDR sequence combination set forth in SEQ ID NO:21/23/25/29/31/33.
3. The method of claim 1 , wherein the antibody or antigen-binding fragment comprises a HCVR/LCVR pair set forth in SEQ ID NO:19/27.
4. The method of claim 1 , wherein the human antibody or antigen-binding fragment is administered to the subject subcutaneously.
5. The method of claim 1 , further comprising administering a second therapeutic agent to the subject.
6. The method of claim 5 , wherein the antibody or antigen-binding fragment and the second therapeutic agent are administered simultaneously or sequentially.
7. The method of claim 5 , wherein the wherein the second therapeutic agent is a non-steroidal anti-inflammatory drug (NSAID), a glucocorticoid, a disease-modifying anti-rheumatic drug (DMARD), a TNF-a antagonist, a T-cell blocker, an anti-CD20 antibody, an IL-1 antagonist, or any combination thereof.
8. The method of claim 5 , wherein the second therapeutic agent is selected from the group consisting of: methotrexate; sulfasalazine; hydroxychloroquine; leflunomide; etanercept; infliximab; adalimumab; golimumab; rilonacept; anakinra; abatacept; cetiolizumab; and rituximab.
9. The method of claim 1 , wherein the therapeutically effective amount of the antibody or antigen-binding fragment is 50 mg to 200 mg.
