Abstract

BACKGROUND: Patients with atopic dermatitis (AD) need safe and effective topical treatments. OBJECTIVE: To assess safety and efficacy of roflumilast cream in patients with mild to moderate AD. METHODS: In this phase 2, proof of concept trial, patients (N=136) aged ≥12 years with AD were randomized to once-daily roflumilast cream 0.15%, roflumilast cream 0.05%, or vehicle cream for 4 weeks. Absolute change from baseline in Eczema Area and Severity Index (EASI) score at week 4 (primary endpoint), percentage change and responder rates, Validated Investigator Global Assessment-AD (vIGA-AD), and safety were assessed. RESULTS: At week 4, mean absolute changes in EASI were −6.4 (P=0.097 vs vehicle), −6.0 (P=0.356), and −4.8 with roflumilast 0.15%, roflumilast 0.05%, and vehicle, respectively. Significant improvements were observed for percentage change from baseline in EASI, patients reaching 75% improvement in EASI, and patients achieving vIGA-AD score of “clear” or “almost clear.” Treatment-related adverse events (AEs) occurred in 2 (2.2%) patients receiving roflumilast (mild rash and moderate application site pain). Only 1 (1.1%) patient receiving roflumilast discontinued study/drug due to an AE. LIMITATIONS: Small number of patients. CONCLUSIONS: Results support additional larger clinical trials of roflumilast cream to assess its potential as a once-daily, nonsteroidal topical AD treatment. CLINICALTRIALS: gov identifier NCT03916081 J Drugs Dermatol. 2023;22(2):139-147. doi:10.36849/JDD.7295.
