Summary
Brief summary
This is a comparative study of CP 690,550, Humira (adalimumab) and placebo on background methotrexate in patients with Rheumatoid Arthritis. The study is intended to provide evidence of the efficacy and safety of CP 690,550 when dosed 5 mg and 10 mg twice a day on background methotrexate in adult patients with moderate to severe Rheumatoid Arthritis. It is intended to confirm the benefits of CP-690,550 in improving signs and symptoms and physical function that were observed in Rheumatoid Arthritis. An active comparator, adalimumab, is also included.
