A Moderate to Severe Rheumatoid Arthritis Study

Summary

The purpose of this study is to determine whether baricitinib 4 milligram (mg) once daily is superior to placebo in the treatment of participants with moderately to severely active Rheumatoid Arthritis (RA) who have had an inadequate response to a tumor necrosis factor (TNF) inhibitor, despite ongoing treatment with conventional disease-modifying antirheumatic drugs (cDMARDs).
