Clinical Trial Summary

This is a Phase 2, 3-week, single-center, double-blind, randomized, two-arm, vehicle controlled study, with each individual receiving both active and vehicle treatment. Approximately 30 subjects with moderate atopic dermatitis will receive topically applied ATx201 CREAM 2% and matching vehicle once daily for 3 weeks (5 mg/cm2/day), without occlusion. ATx201 and vehicle will be applied on two separate target lesions of moderate atopic dermatitis (lesions of at least 3 × 3 cm, excluding the face, scalp, genitals, hands, and feet, ideally from the same anatomical location).
