A Study to Evaluate the Efficacy and Safety of HAT01H in Atopic Dermatitis

This study is a 13 week (91 days) randomized, double-blind, in home use study among 30 male and female subjects with moderate to severe active atopic dermatitis (AD). The study will include subjects with ages 12 - 65 years old inclusive. Group assignments will be balanced by age and disease severity of AD. The study will consist of a 1 week washout period and 12 week treatment phase. During the treatment phase, subject will be provided one of the two test products to use twice daily on all lesions and non-lesional areas as instructed. No additional creams, lotions or soaps other than provided test products will be allowed throughout the duration of the study. Measurements, expert visual assessments and self-assessments will be taken as described below. Safety and tolerability will be evaluated by incidence of AE's (defined per CTCAE), exacerbations, application site reactions/infections, and lab evals. There will also be consumption/compliance checks and dermatological evaluations at each visit.
