Summary

The purpose of this study is to determine the long-term effectiveness and safety of CP-690,550 for the treatment of rheumatoid arthritis. Subjects are eligible for this study only after participating in another "qualifying" study of CP-690,550 A sub-study will be conducted within the A3921024 study, this study will evaluate the immune response to pneumococcal and influenza vaccines in patients receiving CP-690,550
