A Study Comparing 2 Doses Of CP-690,550 Vs. Placebo For The Treatment Of Rheumatoid Arthritis In Patients On Other Background Arthritis Medications

Study Overview
=================
Brief Summary
-----------------
This Phase 3 study is intended to provide evidence that CP-690,550 dosed 5 mg BID and 10 mg BID is safe and effective when used in combination with a variety of traditional disease modifying antirheumatic drugs in adult patients with 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 the Phase 2 rheumatoid arthritis studies.
