Resumo: BACKGROUND: FMX101 4% is a topical minocycline foam for the treatment of moderate-to-severe acne. OBJECTIVE: Evaluate the efficacy and safety of FMX101 4% in treating moderate-to-severe acne vulgaris. METHODS: Two identical phase 3 studies were conducted. Subjects were randomized 2:1 to once-daily FMX101 4% or foam vehicle for 12 weeks. The coprimary end points were the change in inflammatory lesion count from baseline and the rate of treatment success according to the Investigator's Global Assessment (a score of 0 or 1 for clear or almost clear, with a ≥2-grade improvement) at week 12. RESULTS: A total of 961 subjects were enrolled (study 04, N = 466; study 05, N = 495). Compared with vehicle, FMX101 4% demonstrated a significantly greater reduction in inflammatory lesions in both studies (P < .05) and a greater rate of treatment success in study 05 according to the Investigator's Global Assessment (P < .05). Pooled analyses of the 2 studies demonstrated statistical significance for both coprimary end points (all P < .05). Noninflammatory lesion count was also significantly reduced with FMX101 4% versus with vehicle in both studies. FMX101 4% was generally safe and well tolerated. Skin-related adverse events were reported in less than 1% of subjects treated with FMX101 4%. LIMITATIONS: Longer-term efficacy and safety outcomes are needed (ongoing). CONCLUSION: FMX101 4% topical minocycline foam significantly reduced both inflammatory and noninflammatory lesions and improved Investigator's Global Assessment scores in patients with moderate-to-severe acne.
