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 Outcome Measures :
- Proportion of participants with eczema area and severity index (EASI)-75 [ Time Frame: At Week 24 ]
EASI is a composite index measuring the severity & extent of AD based on 4 AD disease characteristics (erythema, thickness [induration, papulation, edema], scratching [excoriation] & lichenification). Total score ranges from 0 (minimum) to 72 (maximum), higher scores indicated greater severity of AD.
EASI-75 is ≥75% reduction from baseline in EASI.
Secondary Outcome Measures :
- Proportion of participants with Investigator's Global Assessment (IGA) = 0 to 1 [ Time Frame: Each Visit, Baseline Through Week 24 ]IGA is an assessment scale used to determine severity of AD and clinical response to treatment on a 5-point scale (0 = clear; 1 = almost clear; 2 = mild; 3 = moderate; 4 = severe) based on erythema and papulation/infiltration.
