Official title
A RANDOMIZED, DOUBLE-BLIND, STUDY COMPARING THE PHARMACOKINETICS AND PHARMACODYNAMICS, AND ASSESSING THE SAFETY OF PF-05280586 AND RITUXIMAB IN SUBJECTS WITH ACTIVE RHEUMATOID ARTHRITIS ON A BACKGROUND OF METHOTREXATE WHO HAVE HAD AN INADEQUATE RESPONSE TO ONE OR MORE TNF ANTAGONIST THERAPIES
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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.
