Use of TNF alpha inhibitor for treatment of erosive polyarthritis
The invention describes methods of treating erosive polyarthritis comprising administering a TNFα antibody, or antigen-binding portion thereof. The invention also describes a method for testing the efficacy of a TNFα antibody, or antigen-binding portion thereof, for the treatment of erosive polyarthritis.
1. A method for treating erosive polyarthritis, comprising administering a human anti-TNFα antibody to a human subject having erosive polyarthritis associated with psoriatic arthritis, ankylosing spondylitis or juvenile rheumatoid arthritis, wherein a modified Total Sharp Score (mTSS) of the subject is maintained or decreased following said treating as compared to baseline prior to said treating, and wherein the human anti-TNFα antibody comprises (1) a light chain variable region (LCVR) comprising the amino acid sequence of SEQ ID NO: 1 and (2) a heavy chain variable region (HCVR) comprising the amino acid sequence of SEQ ID NO: 2.
2. The method of claim 1 , wherein the human subject has erosive polyarthritis associated with psoriatic arthritis.
3. The method of claim 1 , wherein the human subject has erosive polyarthritis associated with ankylosing spondylitis.
4. The method of claim 2 , wherein the change between baseline mTSS of the subject prior to said treating, and mTSS of the subject following said treating, is −0.2.
5. The method of claim 3 , wherein the change between baseline mTSS of the subject prior to said treating, and mTSS of the subject following said treating, is −0.2.
6. The method of claim 1 , wherein said anti-TNFα antibody is adalimumab.
7. The method of claim 6 , wherein said adalimumab is administered to the human subject subcutaneously at a dose of 40 mg on a biweekly dosing regimen.
8. The method of claim 7 , wherein the human subject has erosive polyarthritis associated with psoriatic arthritis.
9. The method of claim 7 , wherein the human subject has erosive polyarthritis associated with ankylosing spondylitis.
10. The method of claim 7 , wherein the change between baseline mTSS of the subject prior to said treating, and mTSS of the subject following said treating, is −0.2.
11. The method of claim 8 , wherein the change between baseline mTSS of the subject prior to said treating, and mTSS of the subject following said treating, is −0.2.
12. The method of claim 9 , wherein the change between baseline mTSS of the subject prior to said treating, and mTSS of the subject following said treating, is −0.2.
13. The method of claim 8 , wherein said treating lasts 24 weeks.
14. The method of claim 8 , wherein the human subject achieves PASI75 response following said treating.
15. The method of claim 8 , wherein the human subject achieves PASI90 response following said treating.
16. The method of claim 8 , wherein the human subject achieves ACR50 response following said treating.
17. The method of claim 8 , wherein the human subject achieves ACR70 response following said treating.
18. The method of claim 9 , wherein the human subject achieves ACR50 response following said treating.
19. The method of claim 9 , wherein the human subject achieves ACR70 response following said treating.
20. A method for treating TNFα-related disorders capable of causing erosive polyarthritis, comprising administering a human anti-TNFα antibody to a human subject having erosive polyarthritis associated with psoriatic arthritis, ankylosing spondylitis or juvenile rheumatoid arthritis, such that radiographic progression in the human subject is inhibited, wherein the human anti-TNFα antibody comprises (1) a light chain variable region (LCVR) comprising the amino acid sequence of SEQ ID NO: 1 and (2) a heavy chain variable region (HCVR) comprising the amino acid sequence of SEQ ID NO: 2.
21. The method of claim 20 , wherein the human subject has erosive polyarthritis associated with psoriatic arthritis.
22. The method of claim 20 , wherein the human subject has erosive polyarthritis associated with ankylosing spondylitis.
23. The method of claim 20 , wherein said anti-TNFα antibody is adalimumab.
24. The method of claim 23 , wherein said adalimumab is administered to the human subject subcutaneously at a dose of 40 mg on a biweekly dosing regimen.
25. The method of claim 24 , wherein the human subject has erosive polyarthritis associated with psoriatic arthritis.
26. The method of claim 24 , wherein the human subject has erosive polyarthritis associated with ankylosing spondylitis.
27. The method of claim 25 , wherein the human subject achieves PASI75 response following said treating.
28. The method of claim 26 , wherein the human subject achieves ACR50 response following said treating.
29. A method for treating structural damage associated with psoriatic arthritis, comprising administering adalimumab subcutaneously at a dose of 40 mg every other week to a human subject having structural damage associated with psoriatic arthritis, such that progression of structural damage in the human subject is inhibited or lessened.
30. The method of claim 29 , wherein the change between baseline mTSS of the subject prior to said treating, and mTSS of the subject following said treating, is −0.2.
