Title: A Phase IIIb, Multi-Center, Randomized, Withdrawal Study to Evaluate the Immunogenicity and Safety of Subcutaneous Administered Abatacept in Adults With Active Rheumatoid Arthritis
Brief Summary: The purpose of the study is to determine whether subcutaneous abatacept administered to patients with rheumatoid arthritis is associated with increased immunogenicity or increased safety events upon withdrawal and reintroduction.


Options:
A: Inclusion Criteria:

* Patients were eligible for this study if they met the American Rheumatism Association classification criteria for RA (9), had a disease duration inferior to one year, suffered from active disease (defined as the presence of a swollen joint count \[SJC\] ≥ 6 \[by the 66 joints count\] and a tender joint count \[TJC\] ≥ 8 \[by the 68 joints count\]) and had not been treated with MTX before.
* Patients were eligible for this study if they met the American Rheumatism Association classification criteria for RA (9), had a disease duration inferior to one year, suffered from active disease (defined as the presence of a swollen joint count \[SJC\] ≥ 6 \[by the 66 joints count\] and a tender joint count \[TJC\] ≥ 8 \[by the 68 joints count\]) and had not been treated with MTX before.
