Title: A Phase 3b, Randomized, Active Controlled Trial to Evaluate the Efficacy and Safety of Abatacept SC in Combination With Methotrexate in Inducing Clinical Remission Compared to Methotrexate Monotherapy in Adults With Very Early RA
Brief Summary: The primary purpose of the protocol is to demonstrate the ability of abatacept plus methotrexate to induce remission in patients with very early rheumatoid arthritis after 12 months of treatment and to maintain remission following 6 months of drug withdrawal.


Options:
A: Inclusion Criteria:

* Must have a clinical diagnosis of rheumatoid arthritis for at least 6 months

* Has a C-reactive protein ≥ 1.0 mg/L OR Erythrocyte Sedimentation Rate (ESR) ≥ 28 mm/hr
* Baseline MRI must show evidence of synovitis in the wrist
* Must have screening laboratory tests within acceptable levels
* Women of childbearing potential and all men must agree to use a medically accepted method of contraception prior to entering the study and continue throughout study up to 6 weeks after study completion
* Must meet tuberculosis (TB) screening criteria
* Have received methotrexate therapy for ≥ 3 months; dose must be stable for at least 8 weeks
* If taking the a disease modifying anti-rheumatic drug (DMARD) in combination with methotrexate must be on a stable dose
