Adapalene/Benzoyl Peroxide Gel 0.3%/2.5%: A Safe and Effective Acne Therapy in All Skin Phototypes

J Drugs Dermatol. 2017 Jun 1;16(6):574-581.


<p>BACKGROUND: Acne affects individuals of all races and ethnicities; however, lighter and darker skin phototypes face different treatment challenges that may affect treatment response and tolerability. This analysis investigated possible differences in the efficacy and safety of the fixed dose combination of 0.3% adapalene with 2.5% benzoyl peroxide (A/BPO gel 0.3%/2.5%) in subjects with Fitzpatrick Skin Types (FST) I-VI.</p> <p>METHODS: This was a post-hoc analysis of a Phase 3, multicenter, randomized, double-blind, parallel-group study of moderate to severe acne in subjects with FST I-VI. Subjects received A/BPO gel 0.3%/2.5%, A/BPO gel 0.1%/2.5% (benchmark), or vehicle, once daily for 12 weeks. Efficacy measurements included success rate (IGA of Clear or Almost Clear), change in inflammatory and noninflammatory lesions from baseline to week 12, safety, and tolerability. The intent to treat (ITT) and safety populations were analyzed. Demographics and disposition were analyzed with descriptive statistics; categorical variables by frequency and percentage; and continuous variables with means, medians, minimum, maximum, and standard deviations.</p> <p>RESULTS: The A/BPO gel 0.3%/2.5% treatment group included 128 subjects with FST I-III, and 89 subjects with FST IV-VI. At week 12, A/BPO gel 0.3%/2.5% was safe, tolerable, and significantly superior to vehicle for all FST and severity groups in inflammatory and noninflammatory lesion reduction (P less than equal to .05). Compared to baseline, 32% of subjects with FST I-III were clear or almost clear, compared to 7% in the vehicle group (P=.001). In FST IV-VI, 28% of subjects were clear or almost clear, compared to 15% for vehicle (P=NS). In all treatment groups and skin phototypes, week 12 tolerability scores were similar to baseline scores, and tolerability scores for most subjects of all skin phototypes were "none" or "mild" for all measures.</p> <p>SUMMARY: We report that the fixed dose combination of A/BPO gel 0.3%/2.5% is efficacious and safe in patients with FST I-VI with moderate and severe inflammatory acne.</p> <p> registry: NCT01880320</p> <p><em>J Drugs Dermatol. 2017;16(6):574-581.</em></p>.
