A Randomized, Double-Blind, Placebo-Controlled Study to Assess the Efficacy and Safety of Nemolizumab in Subjects With Moderate-to-Severe Atopic Dermatitis
A Randomized, Double-Blind, Placebo-Controlled Study to Assess the Efficacy and Safety of Nemolizumab in Subjects With Moderate-to-Severe Atopic Dermatitis
The main purpose of the study was 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 was 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 had a documented history of inadequate response to topical AD medication(s). Approximately 750 subjects were 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). A minimum of 250 subjects were randomized in each PP NRS strata. All nemolizumab-treated subjects who were clinical responders at Week 16 (i.e., the end of initial treatment [Initial Treatment Period]/beginning of Maintenance Period) were re-randomized (1:1:1) to different treatment regimens (nemolizumab injections Q4W or every 8 weeks (Q8W) [with placebo injections at Weeks 20, 28, 36, and 44 to maintain the blind] or placebo Q4W). A clinical responder was defined as a subject at Week 16 with an IGA of 0 (clear) or 1 (almost clear) or a >= 75% improvement in EASI from baseline (EASI-75). All placebo-treated subjects who responded to placebo during the Initial Treatment Period continued to receive placebo Q4W in the Maintenance Period.
