Primary Outcome Measures

Name	Time	Method
Percentage of Participants With an Investigator's Global Assessment (IGA) Score of 0 or 1 and a Reduction ≥2-points From Baseline to Week 16.	Baseline to Week 16	The IGA measures the investigator's global assessment of the participant's overall severity of their AD, based on a static, numeric 5-point scale from 0 (clear skin) to 4 (severe disease). The score is based on an overall assessment of the degree of erythema, papulation/induration, oozing/crusting, and lichenification.
Percentage of Participants Achieving Eczema Area and Severity Index (EASI-75) (≥75% Reduction From Baseline in EASI Score) at Week 16	Baseline to Week 16	The EASI assesses objective physician estimates of 2 dimensions of atopic dermatitis - disease extent and clinical signs affected: 0 = 0%; 1 = 1-9%; 2 = 10-29%; 3 = 30-49%; 4 = 50-69%; 5 = 70-89%; 6 = 90-100% and the severity of 4 clinical signs: (1) erythema, (2) edema/papulation, (3) excoriation, and (4) lichenification each on a scale of 0 to 3 (0 = none, absent; 1 = mild; 2 = moderate; 3 = severe) at 4 body sites (head/neck, trunk, upper limbs, and lower limbs). Half scores are allowed between severities 1, 2, and 3. The final EASI score was obtained by weight-averaging these 4 scores and will range from 0 to 72 (severe).; The EASI responder is defined as a participant who achieves a ≥ 75% improvement from baseline in the EASI score.

Each body region will be assessed for disease extent ranging from 0% to 100% involvement. BSA was calculated using the participant's palm using the 1% rule, 1 palm was equivalent to 1% with estimates of the number of palms it takes to cover the affected AD area. Maximum number of palms were 10 palms for head and neck (10%), 20 palms for upper extremities (20%), 30 palms for trunk, including axilla and groin (30%), 40 palms for lower extremities, including buttocks (40%).
