Summary
Brief summary
In this study, patients with moderate to severe rheumatoid arthritis who are being treated
with methotrexate will receive 2 intravenous treatments with either PF-05280586 or Rituxan
(Rituximab) or MabThera (Rituximab). During the course of the study, the effects of the drugs
will be assessed by sampling the levels of drug in the blood, blood cell counts, and by
comparing these levels among the different treatments. Safety, tolerability and immunologic
response also will be evaluated throughout.
