SAN DIEGO — Treatment with (AD), according to the results of a phase 3 study reported at the annual meeting of the American Academy of Dermatology.
Among patients treated with roflumilast cream, 0.05%, 25.4% reached the primary endpoint of “clear” or “almost clear” plus a two-grade improvement from baseline at week 4 vs 10.7% among those in the vehicle group (P < .0001) in a phase 3 randomized controlled trial of children. The findings were released in a late-breaker session at the meeting.
Roflumilast cream, 0.3% (Zoryve), is approved by the Food and Drug Administration (FDA) for treating psoriasis in patients 6 years and older, and lower doses are being evaluated for AD: 0.15% for adults and children ages 6 and older, and 0.05% for ages 2-5. Roflumilast is a phosphodiesterase-4 inhibitor. In 2023, the FDA accepted a supplemental drug application from the manufacturer, Arcutis, for roflumilast, 0.15%, for treating AD in patients ages 6 and older, based on the results from two recently published phase 3 trials, INTEGUMENT-1 and INTEGUMENT-2.
The study of younger children, INTEGUMENT-PED, recruited 652 patients aged 2-5 with mild to moderate AD, with a Validated Investigator Global Assessment scale for AD (vlGA-AD) score of 2 or 3, a mean body surface area of 22% overall (range, 3%-82%), and an Eczema Area and Severity Index (EASI) score of at least 5. Of the patients enrolled, 437 were assigned to 0.05% roflumilast cream, applied once a day for 4 weeks (mean age, 3.3 years; 51.6% male; 67.4% White; 15.6% Black; 8.5% Asian; 8.5% other or more than one race; 80.5% not Latino/Hispanic). The remaining 215 children were assigned to vehicle cream and had similar characteristics.
About 52% of the patients in both groups had an inadequate response, intolerance, or contraindications to topical corticosteroids (and about 17% for topical calcineurin inhibitors and about 9% for crisaborole).
The proportions of patients who reached “clear” (0) or “almost clear” (1) on the vlGA-AD scale were 35.4% and 14.6%, respectively, at week 4 (P < .0001) for roflumilast and vehicle, respectively, according to the lead author of the study, Lawrence M. Eichenfield, MD, professor of dermatology and pediatrics at the University of California, San Diego, who presented the results at the meeting. In addition, 39.4% and 20.6% achieved an EASI-75 (a secondary endpoint), respectively (P < .0001), and itch also improved within 24 hours of starting treatment.
With regard to safety, 29.7% of patients taking roflumilast had treatment-emergent adverse effects (including upper respiratory tract infections in 4.1%) vs 21.9% of those in the vehicle arm (including upper respiratory tract infections in 1.4%). Reports of pain at the administration site were low (1.6% for roflumilast vs 1.9% for vehicle). Only one patient, a 2-year-old girl, had a treatment-emergent serious adverse event. The child, who was in the roflumilast group, had cellulitis involving noneczematous skin and was treated with antibiotics in the hospital for 3 days. The event was not attributed to roflumilast, which was stopped for 5 days, according to Dr. Eichenfield.
In an interview, Fairfield, Connecticut–based dermatologist Brittany Craiglow, MD, who was not involved in the study, said topical roflumilast would be an “important” new treatment because there are still few nonsteroidal options for the treatment of AD in children under 12. “The excellent local tolerability combined with early improvements in itch and skin clearance will make this a particularly attractive option, if approved,” she said.
Dr. Eichenfield disclosed multiple relationships with various drugmakers. He and several other study authors are investigators and/or consultants for Arcutis and received grants/research funding and/or honoraria. Two authors are Arcutis employees. Other disclosure information for the authors was not immediately available. Dr. Craiglow had no disclosures.
