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).
- received any marketed or investigational biological agent within 12 weeks or 5 half-lives (whichever is longer) prior to Day 1.
- excessive sun exposure, is planning a trip to a sunny climate, has received ultraviolet phototherapy, or has used tanning booths within 4 weeks prior to Day 1, or is not willing to minimize natural and artificial sunlight exposure during the study. Use of sunscreen products (excluding the treatment areas) and protective apparel are recommended when exposure cannot be avoided.
- known or suspected allergy to ATx201 or any component of the investigational product.
