Title: Efficacy and Safety of CDP870 400 mg in Combination With Methotrexate Compared to Methotrexate Alone in the Treatment of the Signs and Symptoms of Patients With Rheumatoid Arthritis Who Are Partial Responders to Methotrexate
Brief Summary: The main purpose of the study was to determine the efficacy of CDP870 in treating RA signs/symptoms in patients who were partial responders to MTX. Other purposes were to show additional efficacy without increased toxicity and the immunogenic response to CDP870 during combined CDP870 and MTX therapy.
