Study Endpoints
Primary Endpoints
Absolute Change From Baseline in Eczema Area and Severity Index (EASI) Total Score at Week 12
Baseline (Day 1) and Week 12

EASI evaluates 4 natural anatomical regions for severity and extent of key disease signs and focuses on the key acute and chronic signs of inflammation (erythema, induration/papulation, excoriation, and lichenification). The maximum total score is 72, with higher values indicating more severe disease. The data presented here is Adjusted mean change after excluding the data from participants who took prohibited medications.

Percentage of Participants Achieving Investigator's Global Assessment (IGA) Response of 0 (Clear) or 1 (Almost Clear) and at Least a 2-Grade Reduction From Baseline at Week 12
Week 12

The IGA allows investigators to assess overall disease severity at one given time point and consists of a 6-point severity scale from clear to very severe disease (0 = clear, 1 = almost clear, 2 = mild disease, 3 = moderate disease, 4 = severe disease, and 5 = very severe disease). A participant has IGA response if they achieve a score of 0 (clear) or 1 (almost clear) and at least a 2-grade reduction from baseline.

Secondary Endpoints
