Abstract
OBJECTIVE: Our objective was to demonstrate the safety, tolerability, and efficacy of a minocycline foam, FMX103, in the treatment of moderate-to-severe facial papulopustular rosacea.
METHODS: This was a phase II, randomized, double-blind, multicenter study. Healthy subjects aged ≥ 18 years with moderate-to-severe rosacea that had been diagnosed ≥ 6 months previously and with ≥ 12 inflammatory facial lesions were randomized (1:1:1) to receive once-daily 1.5% FMX103, 3% FMX103, or vehicle for 12 weeks. The primary endpoint was the absolute change in inflammatory lesion count at week 12. Other assessments included grade 2 or higher Investigator's Global Assessment (IGA) improvement, IGA "clear" or "almost clear" (IGA 0/1), clinical erythema, and safety/tolerability. Safety and efficacy were evaluated at weeks 2, 4, 8, and 12, with a safety follow-up at week 16.
RESULTS: A total of 232 subjects were randomized; 213 completed the study. At week 12, inflammatory lesion count reduction was significantly greater for the 1.5 and 3% FMX103 doses than for vehicle (21.1 and 19.1 vs. 7.8, respectively; both p < 0.001). Both doses were significantly better than vehicle for achieving grade 2 or higher IGA improvement and assessment of "clear" or "almost clear." Both doses appeared generally safe and well tolerated. In total, 11 (4.7%) subjects reported treatment-related treatment-emergent adverse events (TEAEs); all but one (eye discharge) were dermal related, and all resolved by study end. No treatment-related systemic TEAEs were reported. Four subjects discontinued the study because of TEAEs (3% FMX103, n = 3; vehicle, n = 1).
CONCLUSION: Topical minocycline foam, FMX103, appeared to be an effective, safe, and well tolerated treatment for moderate-to-severe papulopustular rosacea. These results support further investigation in larger clinical trials. CLINICALTRIALS.
