Title: A Phase 3, Multi-Center, Randomized, Double-Blind, Placebo-Controlled Study and Open-Label Study to Evaluate the Efficacy and Safety of Abatacept in Combination Therapy With Methotrexate Versus Methotrexate Alone in Subjects With Active Rheumatoid Arthritis and Inadequate Response to Methotrexate
Brief Summary: Short Term: The purpose of this clinical research study is to learn if abatacept (BMS-188667) in combination with methotrexate is better than methotrexate alone in participants that have active rheumatoid arthritis and are not responding to methotrexate. The safety of this treatment will also be studied.

Long Term Extension: The purpose of this amendment is to provide participants who have completed the initial 12-month double-blind treatment period the opportunity to receive open label treatment with active drug treatment until abatacept is approved in the local country or until clinical development has been discontinued.


Options:
A: * Rheumatoid Arthritis (RA) for greater than 1 year from the time of initial diagnosis of RA.
* Participants must have been taking methotrexate for at least 3 months with at least a weekly dose of 15 mg.
B: Inclusion Criteria:

* Diagnosis of RA with active disease defined as: ≥4 swollen joints and ≥6 tender/painful joints, and either have (blood tests) elevated erythrocyte sedimentation rate (ESR) or C-reactive protein (CRP).

* Be receiving either: Oral (tablets) or subcutaneous (injection) methotrexate for at least 6 months prior to randomisation.

Exclusion Criteria:

Exclusion criteria:

* Inflammatory joint disease other than RA, or other systemic autoimmune disorder
* Diagnosis of juvenile rheumatoid arthritis, or RA before the age of 16
* Surgery within 12 weeks of study
* Previous treatment with any approved or investigational biologic agent for RA, an anti-alpha4-integrin antibody or co-stimulation modulator, or cell-depleting therapy
* Concurrent treatment with any biologic agent or DMARD other than methotrexate
