Phase III Study of BMS-188667 (CTLA4Ig) in Patients With Rheumatoid Arthritis Who Are Currently Failing Anti-TNF Therapy or Who Have Failed Anti-TNF Therapy in the Past.

A Phase III, Multi-Center, Randomized, Double-Blind, Placebo-Controlled Study to Evaluate the Efficacy and Safety of BMS-188667 in Subjects With Active Rheumatoid Arthritis on Background Disease Modifying Anti-Rheumatic Drugs (DMARDS) Who Have Failed Anti-Tumor Necrosis Factor (TNF) Therapy

The purpose of this clinical research study is to determine whether abatacept treatment on a background of Disease Modifying Antirheumatic Drugs (DMARDs) will relieve the symptoms of rheumatoid arthritis (RA) in participants who are currently receiving anti-tumor necrosis factor (TNF) therapy for at least 3 months and are not responding or have taken anti-TNF therapy in the last 3 months and did not respond. The safety of treatment with abatacept will also be evaluated. This study also has a 4.5-year long-term extension beginning 6 months after the start of the study.

Double-blind Period (DB); Number of Participants With American College of Rheumatology (ACR) 20 Response at Day 169	ACR 20 response requires a participant to have a 20% reduction in the number of swollen and tender joints, and a reduction of 20% in three of the following five parameters: physician global assessment of disease, participant global assessment of disease, participant assessment of pain, C-reactive protein or erythrocyte sedimentation rate, and degree of disability in Health Assessment Questionnaire (HAQ) score. A participant achieved a sustained ACR 20 response if the participant had ACR 20 observed for at least 2 consecutive study visits.	Day 169
DB; Number of Participants Achieving Clinically Meaningful Improvement in Health Assessment Questionnaire (HAQ)	The disability section of the full HAQ includes 20 questions to assess physical functions in 8 domains: dressing, arising, eating, walking, hygiene, reach, grip and common activities. The questions are evaluated on a 4-point scale: 0=without any difficulty, 1= with some difficulty, 2= with much difficulty, and 3= unable to do. Higher scores= greater dysfunction. A disability index was calculated by summing the worst scores in each domain and dividing by the number of domains answered. Clinically meaningful HAQ response=an improvement of at least 0.3 units from baseline in HAQ disability Index.	Day 169
