A Study to Evaluate the Safety and Efficacy of ATx201 in Subjects With Moderate Atopic Dermatitis
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
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).

used systemic antibiotics or topical antibiotics on the treated areas within 2 weeks prior to Day 1.
used any topical medicated treatment for atopic dermatitis within 2 weeks prior to Day 1, including, but not limited to, topical corticosteroids, calcineurin inhibitors, tars, bleach, antimicrobials, medical devices, and bleach baths.
used systemic treatments (other than biologics) that could affect atopic dermatitis less than 4 weeks prior to Day 1 (e.g., retinoids, calcineurin inhibitors, methotrexate, cyclosporine, hydroxycarbamide [hydroxyurea], azathioprine, oral/injectable corticosteroids).
