Clinical Trial Summary

Primary Objective: To demonstrate that sarilumab monotherapy was superior to adalimumab monotherapy with respect to signs and symptoms as assessed by disease activity score 28 (DAS28)-erythrocyte sedimentation rate (ESR) in participants with active rheumatoid arthritis (RA) who were either intolerant of, or considered inappropriate candidates for continued treatment with methotrexate (MTX), or after at least 12 weeks of continued treatment with MTX, were determined to be inadequate responders. Secondary Objectives: To demonstrate that sarilumab monotherapy was superior to adalimumab monotherapy in participants with active RA who were either intolerant of, or considered inappropriate candidates for continued treatment with MTX, or after at least 12 weeks of continued treatment with MTX, were determined to be inadequate responders, with respect to: - Reduction of signs and symptoms of RA. - Improvement in quality of life assessed by participant reported outcome questionnaires.
