Is this trial a fit for you?

Likely a good fit

Adults aged 18–75 with moderate-to-severe atopic dermatitis (IGA ≥ 3, EASI ≥ 16, BSA ≥ 10%), confirmed by Hanifin-Rajka criteria.

Probably not a fit

Patients with minimal or no response to GS101, or those not meeting baseline severity criteria, may not benefit.

What this trial studies

This is a multicenter, randomized, double-blind, parallel-group phase 3 study comparing GS101 injection to Dupixent® in adults with moderate-to-severe atopic dermatitis. Approximately 572 participants will be enrolled and randomized 1:1 to receive either GS101 or Dupixent®. The study will assess skin severity and symptoms to determine if GS101 provides similar benefits to the established treatment. Eligibility requires adults 18–75 with confirmed atopic dermatitis and moderate-to-severe disease at screening. Key exclusions include intolerance to study products, recent use of other investigational therapies, and recent receipt of live vaccines.

Why it matters

Potential benefit: If GS101 proves similar to Dupixent®, patients may have another therapeutic option for moderate-to-severe atopic dermatitis.

How similar studies have gone: Clinical studies of competing biologic/biologic-like therapies in AD have shown benefit; this study tests a similar approach against an established therapy in a definitive phase 3 setting.
