The main purpose of the study is to assess the efficacy and safety of nemolizumab after a 16-week treatment period in adult and adolescent subjects with moderate-to-severe atopic dermatitis (AD) not adequately controlled with topical treatments.


This is a randomized, double-blind, placebo-controlled, multi-center, parallel-group study in adult and adolescent subjects of age 12 years and above with moderate-to-severe AD. Eligible subjects must have a documented history of inadequate response to topical AD medication(s). Approximately 750 subjects will be randomized in 2:1 to receive either nemolizumab or placebo, stratified by baseline disease severity (Investigator's Global Assessment (IGA) = 3, moderate; IGA = 4, severe) and peak pruritus numeric rating scale (PP NRS) severity (PP NRS = 7; PP NRS < 7).
