Clinical Trial Summary

This study was conducted to assess the safety and tolerability of Abatacept combined with Methotrexate in participants with active rheumatoid arthritis (RA). The secondary objectives were to assess efficacy, pharmacodynamic marker activity, and immunogenicity of Abatacept combined with Methotrexate.

Description:

All participants who completed the 12-month double-blind study period were eligible to continue in the open-label study. Participants received placebo, Abatacept 2 mg/kg, or Abatacept 10 mg/kg in the double-blind study. Participants receiving placebo in the double-blind study were switched 1:1 to continued treatment with placebo or Abatacept 2 mg/kg. Participants receiving Abatacept 2 mg/kg or Abatacept 10 mg/kg continued at the double-blind study dosage. After results from the double-blind period became available, all participants were switched to a weight-tiered 10 mg/kg dose of Abatacept.
