Trial Outcomes & Findings for Safety and Efficacy of ARQ-154 Foam in Subjects With Seborrheic Dermatitis (NCT NCT04091646)

NCT ID: NCT04091646

Last Updated: 2023-07-03

Results Overview

The number of participants achieving "success" in IGA assessment of disease severity at Week 8 is presented for each arm. Success was defined as achievement of an IGA score of 0 ('completely clear') or 1 ('almost clear'), accompanied by a ≥2-grade improvement from baseline IGA score. The IGA is 5-point scale assessing the severity of Seborrheic Dermatitis, with scores ranging from 0 ('completely clear') to 4 ('severe'), and higher scores indicate greater severity. The IGA scores are based on observed data, whereas odds ratio and p-values were calculated using multiple imputation of missing values.

PRIMARY outcome

Timeframe: Week 8

Population: All randomized participants are included, with the exception of those who missed the Week 8 assessment due to COVID-19 disruption.

Population: All randomized participants who provided data are included, with the exception of those who missed the Week 8 assessment due to COVID-19 disruption.

The mean (SD) change from baseline in Overall Assessment of Erythema score at Weeks 2, 4, and 8 is shown. The Erythema Assessment is a simple, single-item scale to assess the subject-reported severity of this symptom, on a scale ranging from 0 ("None: no evidence of erythema.") to 3 ("Severe: Intense \[fiery red\] erythema."). Higher scores indicate greater severity.

The Overall Assessment of Scaling is a simple, single-item scale to assess the subject-reported severity of this symptom, on a scale ranging from 0 ("No scaling: No scaling evident on lesions.") to 3 ("Severe: Coarse, thick scales, with flaking into clothes or skin."). Higher scores indicate greater severity.

The change from baseline in WI-NRS is shown. The WI-NRS is a simple, single-item scale to assess the subject-reported severity of this symptom, on a scale ranging from 0 ("no itch") to 10 ("worst imaginable itch") the subject experienced in the previous 24 hours. Negative values represent a decrease in worst itch from baseline, and positive values indicate an increase.
