Study of Abrocitinib Compared With Dupilumab in Adults With Moderate to Severe Atopic Dermatitis on Background Topical Therapy

This is a randomized, double-blind, double-dummy, active-controlled, multi-center study to assess the efficacy and safety of abrocitinib 200 mg (2 x 100 mg tablets) administered orally QD compared with dupilumab 300 mg administered by subcutaneous injection every other week (as per label guidelines) in adult participants on background topical therapy, with moderate to severe AD. The treatment duration is 26 weeks. A total of approximately 600 participants will be enrolled from approximately 220 sites globally. Approximately 600 participants will be randomly assigned to study intervention. There are primary efficacy assessments at Week 2 and Week 4, and a key secondary efficacy assessment at Week 16. Efficacy and safety endpoints will be assessed throughout the entire study. Exploratory endpoints related to hand eczema efficacy will be assessed throughout the study.
