Summary
This was a multi-center, open-label, non-comparative study that evaluated the long-term safety and efficacy profile of Adapalene/Benzoyl Peroxide Gel.
Subjects were evaluated at Baseline, Weeks 1 and 2, and Months 1, 2, 4, 6, 8, 10, and 12.
Safety was evaluated by spontaneous reports of Adverse Events (AEs), the Local Tolerability Assessment (Erythema, Scaling, Dryness, and Stinging/Burning), routine laboratory testing (hematology, blood chemistry, and urinalysis), and monitoring of suspected sensitizations. Efficacy was evaluated by analysis of Percent Change from Baseline in Inflammatory, Noninflammatory, and Total Lesion Counts, and by the Subject's Assessment of Acne.
