A Phase 3 Trial of Brepocitinib in Dermatomyositis (VALOR Trial)
The VALOR phase 3 trial shows that brepocitinib 30 mg daily — a selective TYK2–JAK1 inhibitor — significantly improves composite disease activity, skin involvement, and muscle strength while enabling steroid discontinuation in adults with treatment-refractory dermatomyositis, marking the first successful phase 3 RCT of an oral targeted agent in this disease.
