Phase 3 Study to Test Safety and Effectiveness of Upadacitinib Tablets in Adolescents and Adults with Severe Alopecia Areata

What this Trial Is About

Alopecia areata AA is a condition where the immune system attacks hair follicles, causing hair loss mainly on the head and face but possibly on other body parts. This research evaluates the safety, effectiveness, and tolerance of upadacitinib, an approved drug, in adolescents and adults with severe AA. The study is a Phase 3 randomized, placebo-controlled, double-blind trial enrolling about 1500 participants worldwide. Participants are randomly assigned to one of three groups receiving different treatments two doses of upadacitinib or placebo. In initial periods, some may switch from placebo to upadacitinib based on their Severity of Alopecia Tool SALT score. Those completing early parts may enter an extension phase receiving upadacitinib for up to 108 weeks. Treatment involves taking oral tablets once daily for up to 160 weeks, with possible re-randomization at Weeks 24 and 52. Throughout the study, participants attend regular clinic visits for medical assessments, blood tests, side effect monitoring, and questionnaires to track treatment effects. Researchers measure hair loss improvement using SALT scores and record adverse events over approximately 164 weeks. Participants are followed for up to 30 days after their last dose for safety monitoring.
