A Study to Evaluate the Efficacy and Safety of Subcutaneous Amlitelimab Monotherapy Compared With Placebo in Participants Aged 12 Years and Older With Moderate-to-severe Atopic Dermatitis
Investigating an Investigational Treatment for Atopic Dermatitis
Study Overview
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).

The above information is not intended to contain all considerations relevant to a potential participation in a clinical trial
This study investigates the efficacy and safety of an investigational medication given as a subcutaneous injection for individuals with moderate-to-severe atopic dermatitis. The study is designed for participants aged 12 years and older whose condition is not adequately managed with topical treatments.
Participants will be randomly assigned to receive either the investigational medication or a placebo, which is an inactive substance that looks like the investigational medicine but does not contain any medicine. The study involves a 24-week treatment period, where the safety and effectiveness of the treatment will be assessed. Participants will have the option to join an extension study after the treatment period.
- Who can participate: Participants aged 12 years and older with a diagnosis of atopic dermatitis for at least one year may be eligible. Key eligibility criteria include a documented history of inadequate response to topical treatments and specific baseline scores for disease severity.
- Study details: Participants will receive either the investigational medication or a placebo through subcutaneous injections. They will be required to attend study visits and comply with study procedures as part of the trial.
- Study timelines and visits: The study will last up to 44 weeks. The study requires up to 10 visits.
