A Study to Evaluate the Safety and Efficacy of MabThera (Rituximab) in Combination With Methotrexate (MTX) in Participants With Active Rheumatoid Arthritis Who Failed on Anti-Tumor Necrosis Factor Alpha Therapy

Completed · Phase 3 · Has a placebo group

Conditions studied: Rheumatoid Arthritis

In brief

This study will assess the safety and efficacy of rituximab combined with MTX in participants with active rheumatoid arthritis (RA) who have had an inadequate response to anti-Tumor Necrosis (TNF) alpha therapy. The anticipated time in the study is up to 2 years and the target sample size is 500 participants. Eligible participants may receive re-treatment with rituximab under a separate protocol WA17531.
