Official Title

A Phase 3, Randomized, Double-blind, Placebo-controlled, Parallel Group, 3-arm, Multinational, Multicenter Study to Evaluate the Efficacy and Safety of Amlitelimab by Subcutaneous Injection in Participants Aged 12 Years and Older With Moderate-to-severe Atopic Dermatitis on Background Topical Corticosteroids ID




Study Description

  • Brief Summary:

    This is a parallel group, Phase 3, multinational, multicenter, randomized, double-blind, placebo controlled, 3-arm study for treatment of participants diagnosed with moderate-to-severe atopic dermatitis (AD) with a history of inadequate response of topical treatment, on background topical corticosteroid (TCS) and/or topical calcineurin inhibitor (TCI). The purpose of this study is to measure the efficacy and safety of treatment with amlitelimab solution for subcutaneous (SC) injection compared with placebo in participants with moderate to severe AD aged 12 years and older on background TCS and/or TCI. Study details include: At the end of the treatment period, participants will have an option to enter a separate study: the blinded extension study EFC17600 (ESTUARY). For participants not entering the blinded extension Study EFC17600 (ESTUARY), the study duration will be up to 44 weeks including a 2 to 4-week screening, a 24-week randomized double-blind period, and a 16-week safety follow-up. For participants entering the blinded extension Study EFC17600 (ESTUARY), the study duration will be up to 28 weeks including a 2 to 4-week screening and a 24-week randomized double-blind period. The total treatment duration will be up to 24 weeks. The total number of visits will be up to 10 visits (or 9 visits for those entering the blinded extension study EFC17600 (ESTUARY).
