Preadolescent moderate acne vulgaris: a randomized trial of the efficacy and safety of topical adapalene-benzoyl peroxides.

Randomized controlled trial
Eichenfield LF, et al. J Drugs Dermatol. 2013.


OBJECTIVE: Evaluate the efficacy and safety of adapalene 0.1%-benzoyl peroxide 2.5% gel (adapalene-BPO) in patients 9-11 years old with acne vulgaris.<BR>

METHODS: Enrolled subjects were male or female, with a score of 3 (moderate) on the Investigator's Global Assessment (IGA) scale. Subjects were randomized to receive adapalene-BPO or vehicle once daily for up to 12 weeks. Efficacy was evaluated by success rate (percentage of subjects rated "clear" or "almost clear") at each visit, median percentage changes from baseline in total, inflammatory and non-inflammatory lesion counts at each visit, the Children's Dermatology Life Quality Index (C DLQI) at baseline and week 12, and the Parent Assessment of Acne at week 12. Safety was assessed through evaluations of adverse events (AEs) and local tolerability [erythema, scaling, dryness, and stinging/burning on scales ranging from 0 (none) to 3 (severe)].<BR>

RESULTS: A total of 142 subjects were randomized to adapalene-BPO and 143 to vehicle. At study endpoint (week 12), adapalene-BPO was significantly superior to vehicle regarding treatment success (49.3% vs 15.9%, respectively), and regarding percentage reduction in total lesion counts (68.6% vs 19.3%), inflammatory (63.2% vs 14.3%), and non-inflammatory lesion counts (70.7% vs 14.6%) (all P<.001). More subjects using adapalene-BPO reported that their acne had no effect on their quality of life, and parents noted that their child's acne significantly improved. Adapalene-BPO was well tolerated, with mean tolerability scores less than 1 (mild).<BR>

CONCLUSIONS: In preadolescents with acne, adapalene-BPO leads to significantly superior treatment success and lesion count reduction compared to vehicle.
