Title: A Multicenter, Double-blind, Randomized, Placebo-controlled, Parallel-group Trial to Assess the Efficacy, Pharmacokinetics, and Safety of CDP870 Without Coadministration of MTX in Japanese Active RA Patients in Whom MTX Cannot be Administrated.
Brief Summary: The objectives of this study are to verify the superiority in efficacy (American College of Rheumatology 20%: ACR20) and investigate the pharmacokinetics and safety of CDP870 versus placebo without coadministration of MTX in active RA patients in whom MTX cannot be administrated.
