Trial Outcomes & Findings for Tapinarof for the Treatment of Atopic Dermatitis in Children and Adults (DMVT-505-3102) (NCT NCT05032859)

NCT ID: NCT05032859

Last Updated: 2025-09-02

Results Overview

The vIGA-AD is a global assessment of the current state of the disease. It is a static 5-point scale used to grade overall disease severity (scalp excluded), as determined by the investigator, using the clinical characteristics of erythema, induration/papulation, lichenification, oozing/crusting. The vIGA-AD ranges from 0 to 4 and is calculated as Clear (0), Almost clear (1), Mild (2), Moderate (3), and Severe (4). Higher vIGA-AD scores represent more severe disease. Statistics are based on 100 imputed datasets.

Population: ITT Population (MI Estimand)

The Eczema Area and Severity Index (EASI) is a scoring system that takes into account the overall severity of disease based on lesion severity and the extent of percent body surface area affected with atopic dermatitis. The EASI is a composite score ranging from 0 -72 that takes into account the degree of erythema, edema/papulation, excoriation, and lichenification (each scored from 0 to 3 separately) for each of four body regions, with adjustment for the percent body surface area involved for each body region relative to the whole body. A higher EASI score represents more severe disease. Statistics are based on 100 imputed datasets.

Population: ITT Population (MI Estimand)

Assessment of percent body surface area (%BSA) is an estimate of the percentage of total involved skin with atopic dermatitis. Estimates were made using the handprint method, where the full palmar hand of the participant (fully extended palm, fingers and thumbs together) represented approximately 1% of the total BSA. Body regions are assigned a specific number of handprints with associated percentages (Head and neck = 10% \[10 handprints\], upper extremities = 20% \[20 handprints\], trunk (including axillae and groin) = 30% \[30 handprints\], lower extremities, including buttocks, = 40% \[40 handprints\]). Estimates of the percent involvement of each body region will be multiplied by the fraction of total body area to obtain the total %BSA involved by region and overall.

Population: ITT Population (MI Estimand)

The Peak Pruritus Numeric Rating Scale (PP-NRS) is used to quickly assess itch/pruritus severity over a 24-hour period. The PP-NRS is scored on a scale of 0 to 10, with 0 being "no itch" and 10 being "worst itch imaginable". The subject will utilize the scale to assess peak pruritis once per day and record the results in their diaries. The daily ratings are averaged to generate a score for the week. Statistics are based on 100 imputed datasets.
