Brief summary

The study is focused on skin of color participants who have moderate-to-severe atopic dermatitis. Atopic dermatitis, also referred to as eczema, is a condition that causes the skin to become itchy, dry, and cracked. From the previous studies on the study drug, it is seen that the study drug has an acceptable safety and effectiveness in participants with atopic dermatitis. The aim of this study is to get additional information on the safety and effectiveness of the study drug, particularly the information on aspects of atopic dermatitis in skin of color participants. The study is looking at several other research questions, including: * What side effects may happen from taking the study drug * How much study drug is in your blood at different times * How much the study drug improves quality of life and mental health

Primary

MeasureTime frameDescription
Percentage of Participants With ≥75% Reduction From Baseline in Eczema Area and Severity Index (EASI) Score (EASI-75)Week 24The EASI score was used to measure the severity and extent of atopic dermatitis (AD) and measures erythema, infiltration, excoriation and lichenification on 4 anatomic regions of the body: head, trunk, upper and lower extremities. The total EASI score ranges from 0 (minimum) to 72 (maximum) points, with the higher scores reflecting the worse severity of AD. EASI-75 responders were the participants who achieved ≥75% overall improvement in EASI score from baseline to Week 24.

Change From Baseline in Weekly Average of Daily PP NRS Score

Peak Pruritus NRS is an assessment tool used by subjects to report intensity of pruritus (itch) during a 24-hour recall period. Participants were asked the following question: For maximum itch intensity: On a scale of 0 to 10, with 0 being 'no itch' and 10 being the 'worst itch imaginable,' how would you rate your itch at the worst moment during the previous 24 hours? For post-baseline NRS, the mean weekly NRS was calculated as the prorated average of the reported daily NRS within the week. A decrease in score indicated improvement.
