Clinical Experience With Once-Daily Dapsone Gel, 7.5% Monotherapy in Patients With Acne Vulgaris.

BACKGROUND
Dapsone gel, 7.5% is a topical medication approved for acne in patients aged 12 years and older. Clinical trials have demonstrated the safety and efficacy of once-daily dapsone gel, 7.5% in patients with moderate acne.


OBJECTIVE
The objective of this report is to describe the clinical course of 8 patients who participated in a 12-week program using once-daily dapsone gel, 7.5% as monotherapy for acne in a real-world clinical setting.


MONOTHERAPY PROGRAM
Male and female adults and adolescents with facial acne, representing a broad range of ages, skin phototypes, and ethnicities, and with no prior use of dapsone gel, 7.5% applied the product once daily for 12 weeks as monotherapy for acne. Photographs were taken at baseline and at 12 weeks. The treating dermatologists recorded observations of baseline disease, treatment tolerability, and outcomes. An independent rater assessed Global Acne Assessment Score (GAAS) at baseline and at 12 weeks based on photographs. Patients provided testimonials of their experience with treatment.


PROGRAM OUTCOMES
Acne improvement was evident in the photographs of the 8 patients. Changes in GAAS at week 12 of treatment, as assessed by an independent rater, ranged from 1- to 3-grade improvement from baseline.


CONCLUSION
Photographs, dermatologist reports, and patient commentary in an office-based practice demonstrated that 12 weeks of treatment with only topical dapsone gel, 7.5%, applied once daily, was effective and well tolerated as a stand-alone treatment in 8 patients with facial acne vulgaris, with results that are consistent with the phase 3 pivotal trials.
