A Study to Assess Immunization Responses in Adult and Adolescent Participants With Moderate-to-Severe Atopic Dermatitis Treated With Nemolizumab

Phase 2
Completed
Conditions
Dermatitis, Atopic
Interventions
Drug: Placebo
Registration Number
NCT04365387
Lead Sponsor
Galderma R&D
Brief Summary

The purpose of this study is to assess the effect of nemolizumab (CD14152) on humoral immune responses to tetanus and meningococcal vaccination in adult and adolescent participants with moderate-to-severe atopic dermatitis (AD).

Detailed Description

This is a randomized, double-blind, placebo-controlled, multi-center, parallel-group study in adult and adolescent subjects (≥ 12 to 54 years) with moderate-to-severe AD. Eligible subjects must have a documented history of inadequate response to topical AD medication(s). Approximately 200 subjects will be randomized 1:1 to receive either 30 mg nemolizumab (with a 60 mg loading dose) or placebo, stratified by baseline disease severity (IGA = 3, moderate; IGA = 4, severe). The study consists of a 2- to 4-week screening period, a 16-week treatment period, and an 8-week follow-up period (12 weeks after the last study drug injection).

PlaceboPlaceboParticipants will receive a placebo via 2 SC injections at baseline. Placebo will then be administered via a single subcutaneous injection Q4W at Weeks 4, 8, and 12.
NemolizumabNemolizumabParticipants will receive a loading dose of nemolizumab (60 milligram \[mg\]) via 2 subcutaneous (SC) injections at baseline. Nemolizumab (30 mg) will then be administered via a single subcutaneous injection every 4 weeks (Q4W) at Weeks 4, 8, and 12.
