PG - 617-29 LID - 10.1002/art.33383 [doi] AB - OBJECTIVE: To compare the efficacy, safety, and tolerability of 5 doses of oral tofacitinib (CP-690,550) or adalimumab monotherapy with placebo for the treatment of active rheumatoid arthritis (RA) in patients with an inadequate response to disease-modifying antirheumatic drugs. METHODS: In this 24-week, double-blind, phase IIb study, patients with RA (n = 384) were randomized to receive placebo, tofacitinib at 1, 3, 5, 10, or 15 mg administered orally twice a day, or adalimumab at 40 mg injected subcutaneously every 2 weeks (total of 6 injections) followed by oral tofacitinib at 5 mg twice a day for 12 weeks. The primary end point was the responder rate according to the American College of Rheumatology 20% improvement criteria (ACR20) at week 12. RESULTS: Treatment with tofacitinib at a dose of >/=3 mg twice a day resulted in a rapid response with significant efficacy when compared to placebo, as indicated by the primary end point (ACR20 response at week 12), achieved in 39.2% (3 mg; P /=3 mg twice a day was efficacious in the treatment of patients with active RA over 24 weeks and demonstrated a manageable safety profile.
