Percent Change From Baseline in Eczema Area and Severity Index (EASI) Score at Each Visit up to Week 52

EASI assesses severity and extent of AD signs through a composite score of erythema, induration/population, excoriation, and lichenification. The severity will be assessed on a scale of 0 (absent) to 3 (severe) for each of the 4 body areas: head/neck, trunk, upper limbs, and lower limbs, with half points allowed. The EASI score can range from 0 to 72 with higher scores representing greater severity of atopic dermatitis.
