About

This is a two-part study that will evaluate the safety and efficacy of APG777 in participants with moderate-to-severe Atopic Dermatitis (AD). Part A will evaluate the safety and efficacy of one induction dose regimen of APG777 compared to placebo. In addition, two maintenance regimens will be evaluated in Part A. Part B will evaluate the benefit-risk of 3 dose regimens of APG777 compared to placebo. One maintenance regimen will be evaluated in Part B. The study duration for any individual participant will be up to 106 weeks which includes: screening, induction, maintenance, and post-treatment follow-up periods. Participants randomized in Part A are not permitted to participate in Part B.
