End point description |
The percentage of participants with vIGA-AD success at Week 4 is presented. The vIGA-AD is a static evaluation of qualitative overall AD severity with five severity grades (reported as score of 0 'clear' to 4 'severe' with higher scores indicating greater symptom severity. vIGA success was defined as score of 'clear' or 'almost clear' plus a 2-grade improvement from baseline. All randomized participants are included, 1 participant in the Roflumilast Cream 0.05% arm was inadvertently treated prior to randomization and thus excluded from analysis.

Achievement of 75% Reduction in the Eczema Area and Severity Index(EASI-75) at Week 4 in Participants With 'Moderate' Baseline vIGA | ||||||||||||
End point description |
The percentage of participants with a moderate baseline vIGA-AD score who achieved EASI-75 is presented. EASI is an instrument to measure the severity and extent of AD. The body is first divided into 4 areas: head (10% of skin), arms (20%), trunk (30%), and legs (40%). Then, the area affected is scored from 0 (0% involvement) to 6 (90-100% involvement), and severity is scored from 0 ('none') to 3 ('severe'). EASI combines the area affected and severity ratings to get a final composite score ranging from 0 (no disease) to 72 (maximal disease). Note that palms and soles were treated as appropriate but were not counted towards any measurements of EASI. All randomized participants are included, with the exception of 1 participant in the Roflumilast Cream 0.05% arm who was inadvertently treated prior to randomization and thus excluded from analysis.
