Summary

This is a parallel group, Phase 3, multinational, multicenter, randomized, double blind, placebo-controlled, 3-arm monotherapy study for treatment of participants diagnosed with moderate to severe atopic dermatitis (AD), whose disease is not adequately controlled with topical prescription therapies or when those therapies are not advisable.

The purpose of this study is to measure the efficacy and safety of treatment with amlitelimab solution for SC injection compared with placebo in participants with moderate to severe AD aged 12 years and older.

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).
