Title: Efficacy and Safety of CDP870 400 mg Subcutaneously Versus Placebo in the Treatment of the Signs and Symptoms of Patients With Rheumatoid Arthritis Who Have Previously Failed at Least One DMARD
Brief Summary: The purpose of this study was to confirm and extend the data from previous studies and to demonstrate the efficacy (in terms of signs and symptoms) and safety of monotherapy with CDP870 administered SC every 4 weeks compared to placebo in patients with active RA who had failed at least one DMARD.

* Have active Rheumatoid Arthritis at the time of screening and at baseline, as defined by 6 or more swollen joints and 6 or more tender joints and additional laboratory criteria

Exclusion Criteria:

* Have other inflammatory diseases, including but not limited to ankylosing spondylitis, systemic lupus erythematosus, Lyme disease

* All patients must fulfill ACR classification criteria for rheumatoid arthritis.
* All patients must have been 16 years of age or older at time of diagnosis of rheumatoid arthritis.
* All patients must be 18 years of age or older at the time of entry into the study.
