The effectiveness of topical acne treatments was not affected by body mass index (BMI) according to study results presented at the American Academy of Dermatology’s Virtual Meeting Experience (AAD VMX) 2021, held online from April 23 to April 25, 2021.
The researchers analyzed data from 5 phase 3 double-blind studies for this post hoc analysis. Patients with moderate to severe acne (overall elevator severity score [EGSS], 3 or 4) were randomly assigned in a 1: 1 ratio to receive once daily clindamycin / benzoyl peroxide gel 1.2% / 3.75% (C / BPO; n = 250), 0.045% tazarotene lotion (n = 798), 0.05% tretinoin lotion (n = 816) or corresponding placebo vehicle for 12 weeks. Participants were stratified into subgroups from underweight to normal (
Among all active treatment recipients, acne lesions were reduced by more than 50% at 12 weeks. Compared to matched placebo cohorts, a grade reduction of at least 2 was observed in normal and underweight EGSS participants and a score of at least “almost clear” was observed in all groups. treatment (C / BPO: 29% vs 15%; tretinoin: 22% vs 10%; tazarotene: 30% vs 16%; all P P

For non-inflammatory lesions, all active treatments reduced the number of lesions at week 12 compared to placebo (all P £ 0.01) except in obese tretinoin recipients (mean change in LS, -44.9% vs. -38.5%). All reported side effects were mild to moderate.
The study authors concluded that topical acne treatments were effective in all participants, reducing the number of inflammatory and non-inflammatory lesions and with an acceptable safety profile.
