TOPLINE:
(AD) in two phase 3 trials.
METHODOLOGY:
- Two randomized, parallel-group, double-blind, vehicle-controlled phase 3 trials, INTEGUMENT-1 (n = 654) and INTEGUMENT-2 (n = 683), enrolled patients aged ≥ 6 years with mild to moderate AD who were randomly assigned in a 2:1 ratio to roflumilast cream 0.15%, a phosphodiesterase 4 inhibitor, or vehicle cream once daily for 4 weeks.
- The primary efficacy endpoint was the Validated Investigator Global Assessment for AD (vIGA-AD) success at week 4, defined as a score of 0 (clear) or 1 (almost clear) plus improvement of at least two grades from baseline.
- Secondary endpoints included vIGA-AD success at week 4 in patients with a baseline score of 3, at least a four-point reduction in the Worst Itch Numeric Rating Scale (WI-NRS), and at least a 75% reduction in the Eczema Area and Severity Index (EASI-75) at weeks 1, 2, and 4.
TAKEAWAY:
- Significantly more patients receiving roflumilast achieved vIGA-AD success at week 4 vs those in the vehicle group in INTEGUMENT-1 (32.0% vs 15.2%; P < .001) and INTEGUMENT-2 (28.9% vs 12.0%; P < .001), which was consistent across all age groups and in those with a baseline score of 3.
- Similarly, a greater proportion of patients treated with roflumilast vs vehicle achieved at least a four-point reduction in WI-NRS at weeks 1, 2, and 4, with improvements noted as early as 24 hours after the first application (P < .05 at all subsequent timepoints).
- The number of patients achieving EASI-75 and vIGA-AD scores of 0 or 1 was significantly higher with roflumilast than with vehicle at weeks 1, 2, and 4.
- Most treatment-emergent adverse events (TEAEs) were mild to moderate, with only 0.9% of the patients experiencing serious TEAEs in each trial. More than 95% of the patients showed no signs of irritation, and over 90% reported no or mild sensation at the application site.
IN PRACTICE:
The two phase 3 randomized clinical trials of patients with AD treated with roflumilast cream 0.15% “demonstrated improvement across multiple efficacy endpoints, including reducing pruritus within 24 hours after application, with favorable safety and tolerability,” the authors wrote. “Additional research, including subgroup analyses, will provide more data regarding the efficacy and safety of roflumilast cream 0.15%, in patients with AD,” they added.
SOURCE:
The study was led by Eric L. Simpson, MD, of the Department of Dermatology, Oregon Health & Science University, Portland, Oregon, and was published online on September 18 in JAMA Dermatology.
LIMITATIONS:
A short duration, a minimum age limit of 6 years, and the lack of an active comparator may influence the interpretation and generalizability of the results.
DISCLOSURES:
The study was sponsored by Arcutis Biotherapeutics. Simpson received grants and personal fees from Arcutis during this study. Three authors reported being employees and/or stockholders of Arcutis, two other authors reported patents for Arcutis, and several authors declared having various ties with various sources, including Arcutis.
