研究概览
简要总结
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

结局指标
主要结局
Percentage of Participants With ≥75% Reduction From Baseline in Eczema Area and Severity Index (EASI) Score (EASI-75)
时间窗: Week 24
The 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.
