Treatment of facial erythema in patients with rosacea with topical brimonidine tartrate: correlation of patient satisfaction with standard clinical endpoints of improvement of facial erythema.

Once-daily brimonidine tartrate (BT) 0.5% gel was shown to provide significantly greater efficacy vs. vehicle for the treatment of facial erythema in patients with rosacea. To demonstrate that patient satisfaction with overall appearance is correlated with reduction in facial erythema, as measured by clinician and patient assessments. Data from two identical phase III, multicentre, randomized, controlled trials of moderate facial erythema of rosacea (study A: n = 260; study B: n = 293) with topical BT 0.5% compared to vehicle gel once-daily for 4 weeks were analysed. Correlations of Patient's Assessment of Appearance (PAA) with Clinician's Erythema Assessment (CEA) and Patient's Self-Assessment (PSA) of erythema were evaluated by calculation of gamma statistics. PAA correlated with CEA post-application on Days 1, 15 and 29 for the intent-to-treat population and provided a median gamma value of 0.57 (min = 0.28, max = 0.61). PAA and PSA was also highly correlated post-application on Days 1, 15 and 29; with a median gamma value of 0.87 (min = 0.66, max = 0.89). Subjects who achieved a clinically meaningful improvement in both CEA and PSA scales were more likely to report satisfaction with the overall appearance of their skin (P < 0.001). Both one- and two-grade improvements in facial erythema assessed by subjects (PSA) and clinicians (CEA) correlate well with PAA, a patient-centered representation of meaningful change.

Brimonidine gel 0.33% rapidly improves patient-reported outcomes by controlling facial erythema of rosacea: a randomized, double-blind, vehicle-controlled study.

Facial redness contributes to impaired psychosocial functioning in rosacea patients and the only approved treatment for erythema is topical brimonidine gel 0.33%. To evaluate patient-reported outcomes, as well as efficacy and safety, in subjects with self-perceived severe erythema treated with brimonidine gel 0.33% compared to vehicle. An 8-day multicenter, randomized study comparing once-daily brimonidine gel 0.33% with vehicle gel using a facial redness questionnaire, subject satisfaction questionnaire and a patient diary of facial redness control to assess patient-reported outcomes. Of the 92 included subjects with self-perceived severe erythema, very few were satisfied with their appearance at baseline (4.2% brimonidine group, 0 vehicle group). On Day 8, significantly more brimonidine group subjects were satisfied with their facial appearance compared to vehicle group (36.9% vs. 21.5%; P < 0.05), with the overall treatment effect (69.6% vs. 40.4%; P < 0.01), and with the improvement in their facial redness (67.4% vs. 33.3%; P < 0.001). More brimonidine group subjects were able to control their facial redness daily (e.g. 83.0% vs. 38.9% on Day 1). On Day 8, significantly more brimonidine group subjects than vehicle group had at least a one-grade improvement from baseline in the Clinician Erythema Assessment score (71.7% vs. 35.7%; P = 0.0011) and Patient Self-Assessment score (76.1% vs. 47.6%; P = 0.004). More subjects in the brimonidine group (29.2%) reported treatment-related adverse events than in the vehicle group (15.9%) but most were mild and transient. Once-daily brimonidine gel 0.33% allowed patients to rapidly control their facial redness and significantly improved patient-reported outcomes in the treatment of persistent facial erythema of rosacea.

Once-daily topical brimonidine tartrate gel 0·5% is a novel treatment for moderate to severe facial erythema of rosacea: results of two multicentre, randomized and vehicle-controlled studies.

Erythema of rosacea is thought to result from abnormal cutaneous vasomotor activity. Brimonidine tartrate (BT) is a highly selective α(2) -adrenergic receptor agonist with vasoconstrictive activity. To determine the optimal concentration and dose regimen of topical BT gel for the treatment of erythema of rosacea and to evaluate its efficacy and safety. In study A, 122 subjects were randomized to receive a single application of BT 0·07%, 0·18%, 0·5% or vehicle. In study B (4-week treatment and 4-week follow-up), 269 subjects were randomized to receive BT 0·5% once daily, BT 0·18% once daily, vehicle once daily, BT 0·18% twice daily or vehicle twice daily. Evaluations included Clinician's Erythema Assessment (CEA), Patient's Self-Assessment (PSA), Chroma Meter measurements and adverse events. In study A, a single application of topical BT gel reduced facial erythema in a dose-dependent fashion. A significant difference between BT 0·5% and vehicle in Chroma Meter redness value was observed from 30min to 12h after application. In study B, BT 0·5% once daily had a statistically superior success profile (defined as a two-grade improvement on both CEA and PSA over 12h) compared with vehicle once daily on days 1, 15 and 29 (all P<0·001). No tachyphylaxis, rebound of erythema or aggravation of other disease signs (telangiectasia, inflammatory lesions) was observed. All regimens were safe and well tolerated with similarly low incidence of adverse events. Once-daily BT gel 0·5% is well tolerated and provides significantly greater efficacy than vehicle gel for the treatment of moderate to severe erythema of rosacea.
