Summary

This is a parallel, Phase 2b, randomized, double-blind, placebo-controlled, multicenter study to assess the efficacy, safety, and tolerability of lunsekimig monotherapy in adult participants (aged 18 to 80 years, inclusive) with moderate-to-severe atopic dermatitis (AD).

This study explores the efficacy and safety of 3 subcutaneous (SC) dose regimens of lunsekimig in adult participants with moderate-to-severe AD who have a documented history, within 6 months prior to baseline, of an inadequate response to topical treatments or for whom topical therapies are not advised. The study consists of 6 arms: 3 parallel dosing regimens and matching placebo arms. Additionally, participants have the option of engaging in a dense pharmacokinetic/pharmodynamic (PK/PD) sampling subgroup.

The study duration will be up to approximately 36 weeks, including up to 4 weeks of screening, 24 weeks of treatment period and an 8-week safety follow-up period.
