A Double-Blind, Randomized, Vehicle-Controlled Phase 2 Study to Assess the Efficacy and Safety of GX-03 in Adult Subjects With Moderate to Severe Atopic Dermatitis (Eczema)
Recruiting now · Phase 2
Conditions studied: Eczema Atopic Dermatitis, Eczema, Atopic Dermatitis
In brief
This is a Phase 2, randomized, double-blind, vehicle-controlled clinical study evaluating the efficacy and safety of GX-03 topical ointment in adult subjects with moderate to severe atopic dermatitis (eczema). The study plans to enroll up to 120 eligible patients with a target of at least 100 completing the study and an ability to expand enrollment up to 200 subjects based on a pre-specified interim assessment conducted by an Independent Data Monitoring Committee (IDMC). Subjects will be randomized in a 1:1 ratio to receive either GX-03 or vehicle control for 8 weeks. The study is designed to evaluate improvement in investigator-assessed disease severity, itch, and patient-reported eczema symptoms following topical treatment with GX-03 compared with vehicle control. Efficacy assessments include the Validated Investigator Global Assessment for Atopic Dermatitis (vIGA-AD™), Eczema Area and Severity Index (EASI), Peak Pruritus Numeric Rating Scale (PP-NRS), and Patient-Oriented Eczema Measure (POEM). An interim assessment of conditional power for the primary efficacy endpoint will occur after the first 50 subjects complete the Week 8 visit or withdraw prematurely. Based on pre-specified criteria defined in the IDMC Charter, the IDMC may recommend continuation as planned, expansion of enrollment up to 200 subjects, or early curtailment of enrollment.
