Trial Outcomes & Findings for Dupilumab in Adolescent and Adult Skin of Color Participants: Open-label Moderate-to-severe Eczema Trial (NCT NCT05590585)

NCT ID: NCT05590585

Last Updated: 2026-01-02

Results Overview

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.

IGA is an assessment scale used to determine severity of atopic dermatitis (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. Therapeutic response was an IGA score of 0 (clear) or 1 (almost clear). Percentage of participants with IGA "0" or "1" are reported at each visit.

Peak Pruritus NRS is an assessment tool used by participants 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.

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

POEM is a 7-item questionnaire that assesses disease symptoms (dryness, itching, flaking, cracking, sleep loss, bleeding and weeping) with a scoring system of 0 (absent disease) to 28 (severe disease) (Higher score indicative of more severe symptoms). Total score was an average of the disease symptoms assessed. A decrease in score indicated improvement.

The Hospital Anxiety and Depression Scale (HADS) is a screening tool designed to assess anxiety and depression. The scale consists of 14 items, divided into two subscales: Anxiety (HADS-A): 7 items; Depression (HADS-D): 7 items. The range of the total score is 0-42 (sum of HADS-A and HADS-D), with higher score indicating more severe overall psychological distress. The two subscales can be reported separately, each with a score range of 0-21, with higher score indicating more severe symptoms of anxiety or depression. A decrease in either the total score or a subscale score indicates improvement.
