Efficacy and safety of oxymetazoline cream 1.0% for treatment of persistent facial erythema associated with rosacea: Findings from the 52-week open label REVEAL trial.

BACKGROUND

Limited treatments are available for persistent erythema of rosacea.

OBJECTIVE

To examine the long-term safety and efficacy of oxymetazoline cream 1.0% in patients with rosacea with moderate-to-severe persistent erythema.

METHODS

Patients applied oxymetazoline once daily for 52 weeks. Safety assessments included treatment-emergent adverse events (TEAEs), skin blanching, inflammatory lesion counts, telangiectasia, disease severity, and rebound effect. Efficacy was assessed by the Clinician Erythema Assessment and Subject Self-Assessment composite score at 3 and 6 hours after the dose on day 1 and at weeks 4, 26, and 52.

RESULTS

Among 440 patients, 8.2% reported treatment-related TEAEs; the most common were application-site dermatitis, paresthesia, pain, and pruritus. The rate of discontinuation due to adverse events (mostly application-site TEAEs) was 3.2%. No clinically meaningful changes were observed in skin blanching, inflammatory lesions, or telangiectasia. At week 52, 36.7%, and 43.4% of patients achieved a 2-grade or greater composite improvement from baseline in both Clinician Erythema Assessment and Subject Self-Assessment 3 and 6 hours after a dose, respectively. Less than 1% of patients experienced a rebound effect following treatment cessation.

LIMITATIONS: A vehicle-control group was not included.

CONCLUSION

This long-term study demonstrated sustained safety, tolerability, and efficacy of oxymetazoline for moderate-to-severe persistent erythema of rosacea.
