Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
1795 enrolled in study and 339 were not randomized due to no longer meeting study criteria (n=214), withdraw of consent (n=83), other reasons (n=32), participant was lost to follow-up (n=5), administrative reason by sponsor (n=2), adverse event (n=2), and poor/non-compliance (n=1). Of 1456 randomized, 15 were not treated.

Reporting Groups
  Description
Abatacept (ABA) Participants received a fixed dose of abatacept approximating 10 mg/kg (500 mg for participants < 60 kg, 750 mg for participants 60 to 100 kg and 1 g for participants > 100 kg). Abatacept was administered intravenously (IV) on Days 1, 15, 29, and every 28 days thereafter, for a total of 14 doses. Participants also received background therapy(ies) for rheumatoid arthritis (RA) (non-biologic or biologic disease-modifying drugs [DMARDs], or combination) throughout the double-blind treatment period.
Placebo (PLA) Participants received Placebo (dextrose 5% water [D5W] for injection U.S.P or normal saline [NS]) for IV infusion administered on Days 1, 15, 29, and every 28 days thereafter, for a total of 14 doses. Participants also received background therapy(ies) for rheumatoid arthritis (RA) (non-biologic or biologic disease-modifying drugs [DMARDs], or combination) throughout the double-blind treatment period.
Open Label (OL) Abatacept Participants received abatacept (weight-tiered 10 mg/kg dose) IV every 28 days during the open-label period.
