About this study

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 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.

Primary outcomes

  1. Percentage of Participants With Investigator's Global Assessment (IGA) Success at Week 16: Intent-To-Treat (ITT) Population

    Time frame: Week 16

    IGA success was defined as an IGA score of 0 (clear) or 1 (almost clear) and at least a 2-grade improvement from baseline to Week 16. The IGA is a 5-point scale ranging from 0 (clear) to 4 (severe) used by the Investigator or trained designee to evaluate the global severity of atopic dermatitis (AD) and the clinical response to treatment. If a participant received any rescue therapy, the data after receipt of rescue therapy was considered treatment failure. Participants with missing data at Week 16 were considered non-responders.

  2. Percentage of Participants With Investigator's Global Assessment (IGA) Success at Week 16: Severe Pruritus Population

    Time frame: Week 16

    IGA success was defined as an IGA score of 0 (clear) or 1 (almost clear) and at least a 2-grade improvement from baseline to Week 16. The IGA is a 5-point scale ranging from 0 (clear) to 4 (severe) used by the Investigator or trained designee to evaluate the global severity of AD and the clinical response to treatment. If a participant received any rescue therapy, the data after receipt of rescue therapy was considered a treatment failure. Participants with missing data at Week 16 were considered non-responders.

  3. Percentage of Participants With >=75% Improvement in Eczema Area and Severity Index (EASI-75) at Week 16: ITT Population

    Time frame: Week 16

    EASI-75 was defined as >=75 percent(%) improvement in EASI from baseline to Week 16. EASI evaluates severity of participants AD based on severity of AD clinical signs and % of body surface area (BSA) affected. Severity of clinical signs of AD(erythema, induration/papulation, excoriation and lichenification)scored separately for each of 4 body regions (head & neck, upper limbs, trunk & lower limbs on 4-point scale: 0= absent; 1= mild; 2= moderate; 3= severe. EASI total score is composite score ranging from 0 to 72. Higher scores represent greater severity of AD. If a participant received any rescue therapy, the data after receipt of rescue therapy was considered a treatment failure. Participants with missing data at Week 16 were considered non-responders.

  4. Percentage of Participants With >=75% Improvement in Eczema Area and Severity Index (EASI-75) at Week 16: Severe Pruritus Population

    Time frame: Week 16

    EASI-75 was defined as >=75 percent(%) improvement in EASI from baseline to Week 16. EASI evaluates severity of participants AD based on severity of AD clinical signs and % of body surface area (BSA) affected. Severity of clinical signs of AD(erythema, induration/papulation, excoriation and lichenification)scored separately for each of 4 body regions (head & neck, upper limbs, trunk & lower limbs on 4-point scale: 0= absent; 1= mild; 2= moderate; 3= severe. EASI total score is composite score ranging from 0 to 72. Higher scores represent greater severity of AD. If a participant received any rescue therapy, the data after receipt of rescue therapy was considered a treatment failure. Participants with missing data at Week 16 were considered non-responders.
