1.Primary Outcome
Title Percent Change From Baseline in Eczema Area and Severity Index (EASI) Total Score at Week 4
Hide Description The EASI quantifies the severity of a participant's atopic dermatitis based on both lesion severity and the percent of BSA affected. The EASI is a composite scoring by the atopic dermatitis clinical evaluator of the degree of erythema, induration/papulation, excoriation, and lichenification (each scored separately) for each of 4 body regions, with adjustment for the percent of BSA involved for each body region and for the proportion of the body region to the whole body. The EASI score can vary in increments of 0.1 and range from 0.0 to 72.0, with higher scores representing greater severity of atopic dermatitis. What is reported is the percent change from baseline in EASI scores.

2.Secondary Outcome
Title Proportion of Participants Achieving Physician's Global Assessment (PGA) Response of Clear or Almost Clear at Week 4
Hide Description The PGA score assesses the overall severity of atopic dermatitis. Scores range from 0 to 4 and correspond to a category (clear, almost clear, mild, moderate, and severe, respectively) based on morphological descriptors.
Time Frame Week 4

4.Secondary Outcome
Title Percent Change From Baseline in Body Surface Area (BSA) Efficacy at Week 4
Hide Description The percent BSA with atopic dermatitis in a body region was determined by the number of handprints of atopic dermatitis skin in that region: head and neck, upper limbs, trunk including axillae, lower limbs including buttocks. In the handprint method, the full palmar hand of the participant (i.e., the participant's fully extended palm, fingers and thumb together) represented approximately 1% of the total BSA. What is reported is the percent change from baseline in BSA affected.

5.Secondary Outcome
Title Change From Baseline in the EASI Clinical Signs Severity Sum Score at Week 4
Hide Description The EASI Clinical Signs Severity Sum Score was derived from the EASI. The Clinical Signs Severity Scores on the 4-point scale for dermatitis lesions were summed in each EASI body region. The sum of the Clinical Signs Severity Score in each EASI body region was then totaled across the 4 EASI body regions to provide an EASI Clinical Signs Severity Sum Score, which ranged from 0 to 48, with higher scores representing greater severity of atopic dermatitis.
