Novel acne drug now under review at the FDA


 

REPORTING FROM THE SDEF HAWAII DERMATOLOGY SEMINAR

Clascoterone cream, a first-in-class topical selective androgen receptor inhibitor for the treatment of acne now under review by the Food and Drug Administration, is already generating considerable buzz in the patient-advocacy community even though the agency won’t issue its decision until August.

“I’ve actually had a lot of interest in this already from parents, especially regarding girls who have very hormonal acne but the parents are really not interested in starting them on a systemic hormonal therapy at their age,” Jessica Sprague, MD, said at the SDEF Hawaii Dermatology Seminar provided by the Global Academy for Medical Education/Skin Disease Education Foundation.

Clascoterone targets androgen receptors in the skin in order to reduce cutaneous 5-alpha dihydrotestosterone.

“It’s being developed for use in both males and females, which is great because at this point there’s no hormonal treatment for males,” noted Dr. Sprague, a pediatric dermatologist at Rady Children’s Hospital and the University of California, both in San Diego.

The manufacturer’s application for marketing approval of clascoterone cream 1% under FDA review includes evidence from two identical phase-3, double-blind, vehicle-controlled, 12-week, randomized trials. The two studies included a total of 1,440 patients aged 9 years through adulthood with moderate to severe facial acne vulgaris who were randomized to twice-daily application of clascoterone or its vehicle.

The primary outcome was the reduction in inflammatory lesions at week 12: a 46.2% decline from baseline with clascoterone 1% cream, which was a significantly greater improvement than the 32.7% reduction for vehicle. The secondary outcome – change in noninflammatory lesion counts at week 12 – was also positive for the topical androgen receptor inhibitor, which achieved a 29.8% reduction, compared with 18.9% for vehicle. Clascoterone exhibited a favorable safety and tolerability profile, with numerically fewer treatment-emergent adverse events than in the vehicle control group. A stronger formulation of the topical agent is in advanced clinical trials for the treatment of androgenetic alopecia in both males and females.

Dr. Sprague reported having no financial conflicts regarding her presentation.
