United States, Argentina, Brazil643 participantsStarted 2024-01-18
Plain-language 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).

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
