A Study to Investigate the Efficacy and Safety of Brepocitinib in Adults With Dermatomyositis

Summary

This is a phase 3, multicenter, randomized, placebo-controlled, double-blind study of treatment with brepocitinib (TYK2/JAK1 inhibitor) in adults with dermatomyositis (DM). The primary objective of this study is to assess the efficacy of two dose levels of brepocitinib in comparison to placebo, as measured by differences in the Total Improvement Score (TIS). After 52 weeks of double-blind treatment, participants have the option to continue therapy in a 52 week open-label extension phase where all participants will receive brepocitinib.
