Official title
A Long-term Safety and Efficacy Study of a Fixed Combination of Adapalene 0.1% and Benzoyl Peroxide 2.5% (Adapalene and Benzoyl Peroxide Topical Gel) Gel in Subjects With Acne Vulgaris
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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.
