Purpose
The purpose of this study is to assess the safety and efficacy of MK-8457 in participants with active rheumatoid arthritis (RA) and an inadequate response or intolerance to anti-TNF-α therapy. The primary hypothesis of this study is that among participants with active RA, MK-8457 100 mg BID will be superior to placebo as measured by the proportion of participants who achieve American College of Rheumatology 20 (ACR20) response after 12 weeks of treatment.
