Description of intervention(s) / exposure
Treatment: Drugs - Abatacept
Treatment: Drugs - Placebo

Active comparator: Abatacept (30/10) - Abatacept (30 mg/kg) was administered as intravenous (iv) infusion over approximately 30 minutes on Days 1 and 15, followed by 10 mg/kg (fixed dose) abatacept infusion on Day 29 and every 28 days thereafter up to and including Day 141. The dose was calculated based on screening visit weight of participants for dosing on Days 1 and 15 followed by fixed dosing as per rheumatoid arthritis label (participants weighing \<60 kg received 500 mg, participants weighing 60 to 100 kg received 750 mg, and participants weighing \>100 kg received 1000 mg) thereafter.

Active comparator: Abatacept (10/10) - Abatacept (10 mg/kg) was administered as iv infusion over approximately 30 minutes on Days 1, 15, and 29 and every 28 days thereafter up to and including Day 141 in the double-blind period and continued for next 18 months in the open-label period till Day 729. All participants received a dose based on their screening visit weight as per rheumatoid arthritis label (participants weighing \<60 kg received 500 mg, participants weighing 60 to 100 kg received 750 mg, and participants weighing \>100 kg received 1000 mg).

Active comparator: Abatacept (3/3) - Abatacept (3 mg/kg) was administered as iv infusion over approximately 30 minutes on Days 1, 15, and 29 and every 28 days thereafter up to and including Day 141. The dose was calculated based on screening visit weight of participants.

Placebo comparator: Placebo - Placebo solution (5% dextrose in water for injection, 0.9% sodium chloride injection) by iv infusion was administered on Days 1, 15, and 29 and every 28 days thereafter till Day 141.
