Dupilumab in Adolescent and Adult Skin of Color Participants: Open-label Moderate-to-severe Eczema Trial

Phase 4
Completed
Conditions
Moderate-to-Severe Atopic Dermatitis
Atopic Eczema
Interventions
Other: Topical emollient (moisturizer)
Registration Number
NCT05590585
Lead Sponsor
Regeneron Pharmaceuticals
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
NameTimeMethod
Proportion of participants with eczema area and severity index (EASI)-75At 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
NameTimeMethod

BSA affected by AD will be assessed for each section of the body using the rule of nines (the possible highest score for each region is: head and neck \[9%\], interior trunk \[18%\], back \[18%\], upper limbs \[18%\], lower limbs \[36%\], and genitals \[1%\]) and will be reported as a percentage of all major body sections combined.
