Abstract
BACKGROUND: Brimonidine tartrate (BT) 0.5% gel demonstrated significantly greater efficacy versus vehicle gel once-daily for the treatment of moderate to severe erythema of rosacea.<BR /> OBJECTIVES: To assess the 30-minute speed of onset of topical BT 0.5% gel in reducing facial erythema in Phase III studies as measured by subject and clinician assessments of erythema.<BR /> METHODS: Two Phase III, randomized, controlled studies with identical design in which subjects with moderate erythema of rosacea (study A: n=260; study B: n=293) were randomized 1:1 to apply topical BT 0.5% or vehicle gel once-daily for 4 weeks. Evaluations included severity of erythema based on Clinician's Erythema Assessment (CEA) and Patient's Self-Assessment (PSA) prior to study drug application and at 30 minutes after application on days 1, 15, and 29.<BR /> RESULTS: 97.7% and 96.6% of subjects reported normal study completion for studies A and B, respectively. The percentage of subjects achieving a 1-grade improvement in both CEA and PSA was significantly increased at 30 minutes post-dosing with BT 0.5% gel compared to vehicle gel on visit days (day 1: 27.9 vs 6.9%, <em>P</em>&lt;0.001; day 15: 55.9 vs 21.1%, <em>P</em>&lt;0.001; Day 29: 58.3 vs 32.0%, <em>P</em>&lt;0.001 for BT 0.5% gel vs vehicle) in study A. Similar results were shown for study B.<BR /> CONCLUSIONS: Once-daily topical BT gel 0.5% is not only efficacious at reducing facial erythema but also exhibits response within 30 minutes of application in a significant number of patients throughout both Phase III studies.<BR /><BR /> <EM>J Drugs Dermatol.</EM> 2014;13(6):699-704.
