WAILEA, HAWAII – The Food and Drug Administration’s approval of adapalene gel 0.1% as an over-the-counter treatment for acne is a potential game changer that could lead to revision of guideline-recommended treatment algorithms, Lawrence F. Eichenfield, MD, predicted at the Hawaii Dermatology Seminar.
In addition to discussing the implications of the FDA’s unprecedented approval of a full prescription–strength topical retinoid for OTC use, he highlighted other developments in topical therapy for acne, including the 2016 approval of dapsone 7.5% gel, as well as several agents with novel mechanisms of action now wending their way through the developmental pipeline.
“This development could be very interesting from an access standpoint and in terms of how physicians write prescriptions for retinoids, in light of the copays for other agents,” said Dr. Eichenfield, professor of dermatology and pediatrics at the University of California, San Diego, and chief of pediatric and adolescent dermatology at Rady Children’s Hospital–San Diego.
“We know that with other retinoids, access is an issue. In Southern California, for example, we have strong pharmacy benefits’ managers for the insurance companies, and they’re very restrictive. It seems like every 3 months, they change the tiering of the different retinoids. It’s something we have to work on to get our patients a fair price,” he explained.
Dapsone 7.5% gel, marketed as Aczone Gel, 7.5% by Allergan, is a once-daily reformulation of the older 5% product administered twice daily. It received FDA approval for use in patients aged 12 years and older based on two 12-week, double-blind, placebo-controlled, randomized trials totaling more than 4,300 acne patients. The studies showed the stronger once-daily product was extremely well tolerated, with application site dryness and itching rates similar to placebo. In terms of efficacy, a Global Acne Assessment Score of 0 or 1 with at least a 2-grade improvement was achieved in 30% of patients assigned to dapsone 7.5% gel, compared with 21% of vehicle-treated controls.
Dr. Eichenfield was lead investigator in a recently published positive phase IIb, randomized, vehicle-controlled study of a topical nitric oxide-releasing agent for acne known for now as SB204 (J Drugs Dermatol. 2016 Dec 1;15[12]:1496-502). The product has both antimicrobial and anti-inflammatory properties, bacteria don’t develop resistance to it, and there is no significant systemic absorption.
“I haven’t seen the data yet. We’ll have to wait and see whether this agent continues to go forward,” Dr. Eichenfield said at the meeting, sponsored by the Global Academy for Medical Education/Skin Disease Research Foundation.
In its press release, Novan stated that the company believes “its cash on hand is sufficient to fund operations at least through the end of 2017, of which the allocation of capital will be dependent upon further assessment of the SB204 phase III trial results.”
DRM01 is a novel topical inhibitor of acetyl coenzyme-A carboxylase, an enzyme involved in synthesis of the fatty acids that are an essential component of sebum. A phase IIb randomized trial in 420 adult acne patients yielded positive results, according to Dermira, which is developing DRM01. The company plans to begin a pivotal phase III trial in the first half of 2017.
Another investigational topical acne therapy to keep an eye on is cortexolone. This peripherally selective antiandrogenic agent is under development by Cassiopea* Pharmaceuticals.
Dr. Eichenfield’s financial disclosures included serving as an investigator for Novan, Regeneron, Galderma, and Astellas Pharma US; and as a consultant for Galderma, Genentech, Janssen, Lilly, Otsuka, and TopMD.
