PG - 1427-35 AB - BACKGROUND: More effective therapies are needed in the specific treatment of severe inflammatory acne vulgaris. OBJECTIVES: To demonstrate superior efficacy of adapalene 0.3%-benzoyl peroxide 2.5% gel (0.3% A/BPO) vs. vehicle, and to assess efficacy of 0.3% A/BPO vs. 0.1% A/BPO in subjects with severe inflammatory acne (Investigator's Global Assessment [IGA] of 4) in the context of a larger trial in a moderate and severe population. METHODS: This was a multicenter, randomized, double-blind, parallel-group, 12-week study. Subjects were randomized to receive 0.3% A/BPO, 0.1% A/BPO (benchmark) or vehicle (comparator) once daily for 12 weeks. Co-primary efficacy endpoints were success rate at week 12 (percentage of subjects rated "clear" or "almost clear," >/= 3-grade IGA improvement), and change in inflammatory (IN) and noninflammatory (NIN) lesion counts from baseline to week 12. Secondary efficacy endpoints were percent changes in IN and NIN lesion counts. Safety endpoints were incidence of adverse events (AEs) and local tolerability signs/symptoms. RESULTS: In the severe inflammatory acne population, a total of 252 subjects were randomized with 106, 112 and 34 subjects in the 0.3% A/BPO, 0.1% A/BPO and vehicle groups, respectively, reaching a high rate of study completion (88.5%). At week 12, both 0.3% A/BPO and 0.1% A/BPO were superior to vehicle in terms of lesion count reduction. However for success rate, only 0.3% A/BPO achieved significantly greater efficacy over vehicle with a treatment difference of 20.1% (31.9% vs. 11.8%; 95% Confidence Interval (CI): [6.0%, 34.2%], P=.029), whereas 0.1% A/BPO did not (treatment difference vs. vehicle of 8.8%; P=.443). This translates to an 11% difference between active treatments in favor of 0.3% A/BPO. Also, 0.3% A/BPO was safe and well tolerated. CONCLUSIONS: Availability of this new treatment option should allow clinicians to better customize severe inflammatory acne management, and the high-strength product provides a step-up treatment when needed.
