RESUMEN

An unmet need exists for a safe, tolerable, effective treatment for moderate to severe persistent facial erythema in patients with rosacea. This pivotal phase 3, multicenter, double-blind study evaluated the efficacy and safety of topical oxymetazoline in patients with facial erythema associated with moderate to severe rosacea. Patients were randomly assigned to treatment with oxymetazoline hydrochloride cream 1.0% or vehicle applied once daily for 29 days, and were followed for 28 days posttreatment. The primary efficacy outcome was having at least a 2-grade decrease from baseline on both the Clinician Erythema Assessment (CEA) and the Subject Self-Assessment for rosacea facial redness (SSA) scales (composite success) at 3, 6, 9, and 12 hours postdose on day 29. Safety assessments included treatment-emergent adverse events (TEAEs) and posttreatment worsening of erythema (composite CEA/SSA increase of 1-grade severity from baseline; rebound effect). A total of 440 patients (mean age, 49.5 years; 78.9% females) were randomized (oxymetazoline, n=222; vehicle, n=218); most had moderate erythema. On day 29, significantly greater proportions of oxymetazoline recipients achieved the primary efficacy outcome at each time point (P less than 0.02) and overall (P less than 0.001) compared with vehicle recipients. The incidence of discontinuation due to TEAEs was low in both groups (oxymetazoline group, 1.8%; vehicle group, 0.5%). The most common TEAEs reported during the entire study period were application-site dermatitis, application-site erythema, and headache in the oxymetazoline group (1.4% each), and headache (0.9%) in the vehicle group. Following cessation of treatment, low proportions of patients experienced rebound effect (oxymetazoline group, 2.2%; vehicle group, 1.1%). Oxymetazoline applied to the face once daily for 29 days was effective, safe, and well tolerated in patients with moderate to severe persistent facial erythema of rosacea.

RESUMEN

Background: Rosacea is a chronic dermatologic condition with limited treatment options. Methods: Data were pooled from two identically designed phase 3 trials. Patients with moderate to severe persistent erythema of rosacea were randomized to receive oxymetazoline cream 1.0% or vehicle once daily for 29 days and were followed for 28 days posttreatment. The primary efficacy outcome was the proportion of patients with ≥2-grade improvement from baseline on both Clinician Erythema Assessment (CEA) and Subject Self-Assessment (SSA) at 3, 6, 9, and 12 hours postdose, day 29. Results: The pooled population included 885 patients (78.8% female); 85.8% and 91.2% had moderate erythema based on CEA and SSA, respectively. The primary outcome was achieved by significantly more patients in the oxymetazoline than vehicle group (P<0.001). Individual CEA and SSA scores and reduction in facial erythema (digital image analysis) favored oxymetazoline over vehicle (P<0.001). The incidence of treatment-emergent adverse events was low (oxymetazoline, 16.4%; vehicle, 11.8%). No clinically relevant erythema worsening (based on CEA and SSA) was observed during the 28-day posttreatment follow-up period (oxymetazoline, 1.7%; vehicle, 0.6%). Conclusion: Oxymetazoline effectively reduced moderate to severe persistent facial erythema of rosacea and was well tolerated. J Drugs Dermatol. 2018;17(11):1201-1208.

RESUMEN

BACKGROUND: Side effects may limit the use of current tetracycline-class antibiotics for acne. OBJECTIVE: Evaluate the efficacy and safety of once-daily sarecycline, a novel, narrow-spectrum tetracycline-class antibiotic, in moderate to severe acne. METHODS: Patients 9-45 years with moderate to severe facial acne (Investigator's Global Assessment [IGA] score ≥ 3, 20-50 inflammatory and ≤ 100 noninflammatory lesions, and ≤ 2 nodules) were randomized 1:1 to sarecycline 1.5 mg/kg/day or placebo for 12 weeks in identically designed phase 3 studies (SC1401 and SC1402). RESULTS: In SC1401 (sarecycline n=483, placebo n=485) and SC1402 (sarecycline n=519, placebo n=515), at week 12, IGA success (≥ 2-grade improvement and score 0 [clear] or 1 [almost clear]) rates were 21.9% and 22.6% (sarecycline), respectively, versus 10.5% and 15.3% (placebo; P less than 0.0001 and P equals 0.0038). Onset of efficacy in inflammatory lesions occurred by the first visit (week 3), with mean percentage reduction in inflammatory lesions at week 12 in SC1401 and SC1402 of -51.8% and -49.9% (sarecycline), respectively, versus -35.1% and -35.4% (placebo; P less than 0.0001). Onset of efficacy for absolute reduction of noninflammatory lesion count occurred at week 6 in SC1401 (P less than 0.05) and week 9 in SC1402 (P less than 0.01). In SC1401, the most common TEAEs (in ≥ 2% of either sarecycline or placebo group) were nausea (4.6% [sarecycline]; 2.5% [placebo]), nasopharyngitis (3.1%; 1.7%), headache (2.7%; 2.7%), and vomiting (2.1%; 1.4%) and, in SC1402, nasopharyngitis (2.5%; 2.9%) and headache (2.9%; 4.9%). Most were not considered treatment-related. Vestibular (dizziness, tinnitus, vertigo) and phototoxic (sunburn, photosensitivity) TEAEs both occurred in ≤ 1% of sarecycline patients. Gastrointestinal TEAE rates for sarecycline were low. Among females, vulvovaginal candidiasis (SC1401: 1.1% [sarecycline] and 0 [placebo]; SC1402: 0.3% and 0) and mycotic infection (0.7% and 0; 1.0% and 0) rates were low. CONCLUSION: The narrow-spectrum antibiotic sarecycline was safe, well tolerated, and effective for moderate to severe acne, with low rates of side effects common with tetracycline antibiotics.

RESUMEN

BACKGROUND: A hydroquinone (HQ) skin care system has been designed for use in conjunction with nonsurgical procedures. OBJECTIVE: The authors evaluate the efficacy of this system plus tretinoin for improving facial appearance in comparison to a standard skin care regimen in users of botulinum toxin Type A (BoNT-A). METHODS: In this multicenter, randomized, investigator-masked, parallel-group study, 61 patients who received upper facial treatment with BoNT-A at a plastic surgery or dermatology clinic were randomly assigned to apply either the HQ system (cleanser, toner, proprietary 4% hydroquinone, exfoliant, and sunscreen) plus 0.05% tretinoin cream or a standard skin care regimen (cleanser, moisturizer, and sunscreen) for 120 days. Outcomes were assessed by the investigators and through a patient questionnaire. RESULTS: Compared with standard skin care, the HQ system plus tretinoin resulted in significantly milder fine lines/wrinkles and hyperpigmentation at Days 30, 90, and 120 (p ≤ .05) and significantly superior overall ratings for each of nine patient assessments at Days 90 and 120 (p ≤ .05). A relatively greater proportion of patients using the HQ system plus tretinoin believed that their study treatment had further enhanced the improvements attained with BoNT-A (86% vs 8%). Both regimens were generally well tolerated. CONCLUSIONS: Adjunctive use of the HQ system plus tretinoin can further enhance the improvements in facial appearance attained with BoNT-A. Applying the HQ system plus tretinoin offers multiple clinical benefits over standard skin care, including significantly greater improvements in fine lines/wrinkles and hyperpigmentation.

RESUMEN

BACKGROUND: As the treatment indications for the Cohesive Polydensified Matrix® hyaluronic acid (CPM-HA) portfolio continue to expand and diversify, injectors new to the range or those who are expanding the treatments they offer may be unsure of the optimal product and injection technique for specific facial areas. Each product in the CPM-HA portfolio has been intentionally designed to provide the best physical properties for a specific indication and target tissue. This document has been developed to provide a comprehensive, one-stop reference for clinicians using the portfolio. METHODS: An international panel of experts in the field of aesthetic medicine convened to develop guidelines on effective and safe injection technique when performing treatments with the CPM-HA range of soft-tissue fillers. RESULTS: Consensus members considered treatment indications in the upper, middle and lower face. Landmark deficiencies and anatomical considerations are described for each indication and consensus recommendations provided on the optimal product, injection depth and treatment technique. This is supplemented by the experts advice on avoidance of complications. Throughout, an evidence-based approach to selection of products and injection techniques is provided. The result is a fully tailored approach to a range of indications covering the full portfolio of CPM-HA products, including the newest addition for skin revitalization. CONCLUSION: The recommendations in this consensus document are provided to assist clinicians in the selection of CPM-HA products, administration techniques and depths of injection with the aim of providing seamless and natural treatment results, enhanced safety and patient satisfaction.

RESUMEN

Synergistic interaction of multiple growth factors (GF) in skin controls the processes that promote skin repair. GFs have been shown to affect different pathways of skin repair and rejuvenation with many GFs working in close cooperation with one another and with other endogenous agents. Intrinsic and extrinsic aging of skin reduces both the levels of natural GFs and the number and activity of fibroblasts. Supplementing skin's endogenous GFs may enhance natural repair processes and accelerate the reversal of damage caused by intrinsic and extrinsic skin aging. In spite of their large molecular weight, evidence suggests that a small fraction of topically applied GFs penetrating into superficial epidermis can elicit a fibroblast-mediated response in the dermis. GF mixture secreted by human fibroblasts grown in conditions resembling the physiological condition of dermis, and present at high concentrations in a stable formula is most likely to provide an ideal cosmeceutical product. This naturally balanced mixture is also likely to contain other important, but as yet unidentified, substances that affect skin healing. Such a complex mixture cannot be reproduced using synthetic substances. Clinical studies have shown that topical application of products containing high concentrations of a physiologically balanced mixture of GF appears to reverse the signs of skin aging. A synergistic combination of antioxidants, matrix building agents and skin conditioners with physiologically balanced GF provides a novel and comprehensive paradigm of skin rejuvenation.

RESUMEN

It is timely to compare the efficacy and tolerability of 2 actinic keratosis (AK) therapies--5% 5-fluorouracil (5-FU) cream and imiquimod cream. Thirty-six patients with 4 or more AKs were randomly assigned to receive 5% 5-FU cream twice daily for 2 to 4 weeks or 5% imiquimod cream twice weekly for 16 weeks. Five percent 5-FU was more effective than imiquimod in exposing what were presumed to be subclinical AKs, reducing the final AK count (total AK count declined during the 24-week study by 94% vs. 66%, P < .05), achieving complete clearance (incidence of 84% vs. 24% by week 24, P < .01), and achieving clearance rapidly. Tolerability was similar except for erythema, which was initially significantly higher with 5-FU than imiquimod but resolved rapidly and was significantly lower than imiquimod by week 16. Five percent 5-FU remains the gold standard field therapy for AKs.
