A Phase 3b/4 Randomized Double Blind Placebo Controlled Study Of Methotrexate (MTX) Withdrawal In Subjects With Rheumatoid Arthritis (RA) Treated With Tofacitinib 11mg Modified Release (MR) Formulation

This study is designed to evaluate the efficacy and safety of tofacitinib modified release formulation (11mg QD) versus tofacitinib modified release formulation plus continued methotrexate treatment in subjects with moderate to severe rheumatoid arthritis who are insufficiently responding to their stable dose of methotrexate treatment.
