Uses and Compositions for Treatment of Psoriatic Arthritis
The invention provides methods, uses and compositions for the treatment of psoriatic arthritis. The invention describes methods and uses for treating psoriatic arthritis, wherein a TNFα inhibitor, such as a human TNFα antibody, or antigen-binding portion thereof, is used to psoriatic arthritis in a subject. Also described are methods for determining the efficacy of a TNFα inhibitor for treatment of psoriatic arthritis in a subject.
1 . A method of determining the efficacy of a TNFα inhibitor for treating psoriatic arthritis in a subject comprising:
determining an ACR20 response of a patient population having psoriatic arthritis who was administered the TNFα inhibitor,
wherein an ACR20 response in at least about 39% of the patient population indicates that the TNFα inhibitor is an effective TNFα inhibitor for the treatment of psoriatic arthritis.
2 . The method of claim 1 , further comprising administering the effective TNFα inhibitor to a subject to treat psoriatic arthritis.
3 - 30 . (canceled)
31 . A method of determining the efficacy of a TNFα inhibitor for treating psoriatic arthritis in a subject comprising:
determining a PASI50 response of a patient population having psoriatic arthritis who was administered the TNFα inhibitor,
wherein a PASI50 response in at least about 73% of the patient population indicates that the TNFα inhibitor is an effective TNFα inhibitor for the treatment of psoriatic arthritis in a subject.
32 . The method of claim 31 , further comprising administering the effective TNFα inhibitor to a subject to treat psoriatic arthritis.
33 - 51 . (canceled)
52 . A method of determining the efficacy of a TNFα inhibitor for treating psoriatic arthritis in a subject comprising:
determining a PGA response of “Clear” or “Almost Clear,” of a patient population having psoriatic arthritis who was administered the TNFα inhibitor,
wherein a PGA response of “Clear” or “Almost Clear,” in at least about 40% of the patient population indicates that the TNFα inhibitor is an effective TNFα inhibitor for the treatment of psoriatic arthritis in a subject.
53 . The method of claim 52 , further comprising administering the effective TNFα inhibitor to a subject to treat psoriatic arthritis.
54 - 93 . (canceled)
