Safety and Tolerability of Sarecycline for the Treatment of Acne Vulgaris: Results from a Phase III, Multicenter, Open-Label Study and a Phase I Phototoxicity Study.

Abstract:
Objective: We sought to evaluate the safety, tolerability, and patterns of use for the once-daily oral, narrow-spectrum antibiotic sarecycline in patients with moderate-to-severe acne vulgaris during a 40-week Phase III, multicenter, open-label extension study. Participants: Patients aged nine years or older with moderate-to-severe acne who completed one of two prior Phase III, double-blind, placebo-controlled, 12-week trials in which they received sarecycline 1.5mg/kg/day or placebo were included. Measurements: The primary assessment was the safety of sarecycline 1.5mg/kg/day for 40 weeks as indicated by adverse events (AEs), vital signs, electrocardiograms, clinical laboratory tests, and physical examinations. Patterns of sarecycline use were a secondary assessment. Results: The safety population included 483 patients; 354 patients (73.3%) completed the study. The most common reasons for premature discontinuation were withdrawal by the patient (14.5%), lost to follow-up (7.9%), and AEs (2.5%). The most common treatment-emergent AEs (TEAEs) were nasopharyngitis (3.7%), upper-respiratory-tract infection (3.3%), headache (2.9%), and nausea (2.1%). Clinical laboratory evaluations suggested no clinically meaningful differences between the treatment sequences. Rates of TEAEs commonly associated with other tetracycline antibiotics include dizziness (0.4%) and sunburn (0.2%), and for gastrointestinal TEAEs, nausea (2.1%), vomiting (1.9%), and diarrhea (1.0%). Also reported herein are the results of a Phase I phototoxicity study. Conclusion: Patients aged nine years or older with moderate-to-severe acne vulgaris who received sarecycline once daily for up to 40 weeks showed low rates of TEAEs, with nasopharyngitis, upper-respiratory-tract infection, headache, and nausea being the only TEAEs reported by 2% or more of patients. No clinically meaningful safety findings were noted. ClinicalTrials.gov Registration: NCT02413346.
