Primary outcomePrimary: Number of Participants With Either an Infection or a Grade III or IV Adverse Event (National Cancer Institute Common Toxicity Criteria for Adverse Events [NCI CTCAE], Version 3.0) — 14; 11; 5; 4 Participants
Summary
This was a Phase II, randomized, double-blind, multicenter study designed to evaluate the safety and efficacy of rituximab, administered at two different regimens for 2 years, in patients with moderate to severe active rheumatoid arthritis (RA) receiving stable doses of methotrexate (MTX).
