| Popis: | Acne treatment guidelines suggest a combination approach with topical therapy including a topical retinoid, benzoyl peroxide and an oral antibiotic, or oral isotretinoin (OI), as first-line treatment options for severe acne vulgaris (AV). This study evaluated the efficacy and safety of a daily regimen of 0.3% adapalene and 2.5% benzoyl peroxide (0.3% A/BPO) gel and oral doxycycline 100 mg twice daily in severe (nonnodulocystic, non-conglobate) inflammatory AV.This was a phase 4, 12-week, single-arm, openlabel, multi-center investigational study. Subjects (males and females, 12 or older, with severe inflammatory AV, Investigator Global Assessment [IGA] 4, and less than equal to 4 nodulocystic lesions, n=186) were considered OI candidates at baseline by the investigator. OI candidacy was re-evaluated at each study visit. Efficacy endpoints included inflammatory lesion (IL) reduction (week 12), IGA success (defined as IGA 0 [Clear] or 1 [Almost Clear], weeks 4, 8, and 12), percent reduction in lesions (weeks 4, 8, and 12), and subject questionnaires (week 12). Safety assessments included adverse events (AEs) and tolerability.Mean IL counts were significantly reduced from baseline to the end of the study (mean [SD]; baseline, 44.8 (21.73); week 12, 14.8 (16.11); mean percent reduction, 66.2% [30.47]; P less than .0001). By week 12, 37.1% of subjects achieved IGA Success (n=69, P less than .0001). Most subjects self-reported at least moderate improvement in AV (90.2%), and were "Satisfied" or "Very Satisfied" with the study treatment overall (83.2%). 41.9% of the subjects were no longer considered by their investigator to be OI candidates at week 4. At 12 weeks, only 19.9% were still considered OI candidates.0.3% A/BPO + DOX is an effective and safe treatment option for severe inflammatory AV, before starting OI treatment, or as an alternative when OI cannot be used.
