Brief 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 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 18 years
and older. Study details include:• The study
duration will be up to 28 weeks for participants entering the blinded extension
study (EFC17600 [ESTUARY]) including a 2 to 4-week screening and a 24-week
randomized double-blind period.
• The study
duration will be up to 44 weeks for participants not entering the blinded
extension study (EFC17600 [ESTUARY]) including a 2 to 4-week screening, a
24-week randomized double-blind period, and a 16-week safety follow-up.
• The total treatment
duration will be up to 24 weeks
