Evaluating Amlitelimab for Moderate-to-Severe Atopic Dermatitis

A Phase 3, Randomized, Double-blind, Placebo-controlled, Parallel-group, 3-arm, Multinational, Multicenter Study to Evaluate the Efficacy and Safety of Amlitelimab by Subcutaneous Injection in Participants Aged 12 Years and Older With Moderate-to-severe Atopic Dermatitis (AD) Who Are on Background Topical Corticosteroids and Have Had an Inadequate Response to Prior Biologic Therapy or Oral Janus Kinase (JAK) Inhibitor Treatment

Phase 3 Interventional Sanofi · NCT06241118

This study is testing a new injection called amlitelimab to see if it can help people aged 12 and older with moderate-to-severe eczema who haven't had success with other treatments.

What this trial studies

This Phase 3 clinical trial investigates the efficacy and safety of subcutaneous amlitelimab in participants aged 12 years and older with moderate-to-severe atopic dermatitis (AD) who have not responded adequately to previous biologic therapies or oral JAK inhibitors. The study is designed as a randomized, double-blind, placebo-controlled trial with three arms, comparing amlitelimab to placebo while participants continue their topical corticosteroid therapy. The trial will last up to 56 weeks, including a screening period, a randomized treatment phase, and a safety follow-up. Participants may also have the option to enter a long-term safety study after the trial concludes.

Who should consider this trial

Good fit: Ideal candidates are individuals aged 12 years and older with a diagnosis of moderate-to-severe atopic dermatitis and a history of inadequate response to prior biologic therapy or oral JAK inhibitors.

Not a fit: Patients with significant skin co-morbidities or those with current immunosuppression may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new effective option for patients with moderate-to-severe atopic dermatitis who have not responded to existing therapies.

How similar studies have performed: Previous studies have shown promise with similar biologic therapies for atopic dermatitis, indicating potential for success with this approach.
