Phase 3 Study of Subcutaneous Amlitelimab with Topical Corticosteroids in Participants 12 Years and Older With Moderate-to-Severe Atopic Dermatitis Who Did Not Respond to Prior Biologic or Oral JAK Inhibitor Treatments

What this Trial Is About

Researchers are evaluating the efficacy and safety of amlitelimab, given as a subcutaneous injection, for treating moderate-to-severe atopic dermatitis AD in participants aged 12 years and older. This Phase 3, randomized, double-blind, placebo-controlled study includes participants who have not responded adequately to prior biologic or oral Janus kinase inhibitor JAKi therapies while using background topical corticosteroids TCS. Participants are randomly assigned to one of three groups receiving subcutaneous injections of either one of two doses of amlitelimab or a placebo, all alongside background TCS therapy. The treatment period lasts up to 36 weeks, followed by either a 16-week safety follow-up for those not entering the long-term safety study or no further treatment period for those entering the extension study. The entire study duration ranges up to 56 weeks for participants not entering the long-term safety study and up to 40 weeks for those who do. Participants will attend up to 13 visits during the study, or 12 visits if they join the long-term safety study. Assessments include evaluating skin condition using standardized scales such as the Validated Investigator Global Assessment for AD and the Eczema Area and Severity Index. Researchers will monitor safety, side effects, skin symptoms, quality of life, and various patient-reported outcomes. Long-term safety and response to treatment will also be observed for those who continue into the extension study.
