According to the company, the gel treats both inflammatory and non-inflammatory acne in a once-a-day application with a new pump delivery system. Allergan says 4,340 acne patients were studied in two identically designed 12-week trials in which Aczone’s safety and efficacy were assessed. FDA approved the product based on co-primary endpoints of the Global Acne Assessment Score and lesion counts (20 to 50 inflammatory and 30 to 100 non-inflammatory lesions at baseline), the company says. Allergan reports study results at week 12 showed that inflammatory lesions were reduced by 15.8 lesions vs 13.9 lesions with vehicle and non-inflammatory lesions were reduced by 20.7 lesions vs 18.0 lesions with vehicle (39.4%). It adds that out of 2161 patients who used Aczone Gel, 7.5%, 1.1% experienced mild application-site dryness vs 1.0% with vehicle and 0.9% experienced pruritus vs 0.5% with vehicle.
