| Study type | Interventional |
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.
