A subgroup analysis to evaluate the efficacy and safety of adapalene-benzoyl peroxide topical gel in black subjects with moderate acne

Abstract

Three multicenter, randomized, double blind, parallel-group, placebo controlled studies involving 3,855 subjects established the safety and efficacy of an adapalene benzoyl peroxide topical gel in the treatment of acne for all skin types. The data from these 3 studies were pooled and the subgroup of self-identified black subjects was analyzed separately. Significantly more black subjects had IGA success with adapalene-BPO than with vehicle at week 12. Significantly more black subjects also had decreased total, inflammatory, and noninflammatory lesion counts with adapalene-BPO that were seen as early as week 1. Adapalene-BPO was well tolerated in the black subjects included in this analysis and no cases of treatment-related PIH were observed. Similar results were obtained for this subgroup as the overall population from the 3 studies. Based on the results from this analysis, adapalene-BPO is a safe and effective treatment for acne in black skin.
