A phase 3 efficacy and safety study of tapinarof for the treatment of moderate to severe atopic dermatitis in children and adults

Clinical Trial Details

This study is an 8-week double-blind, vehicle-controlled treatment study in which subjects will be randomized to receive tapinarof cream, 1% or vehicle cream once daily for 8 weeks. At the end of the 8-week study treatment, qualified subjects will have the option to enroll in an open-label, long-term extension study for an additional 48 weeks of treatment. Subjects who do not participate in the open-label, long-term extension study will complete a follow-up visit approximately one week after the end of treatment in this study.
