RESUMEN

INTRODUCTION: A three-pronged approach to acne treatment combining an antibiotic, antimicrobial, and retinoid may be more efficacious than single/double treatments while potentially reducing antibiotic resistance. This study evaluated the efficacy and safety of the first fixed-dose, triple-combination topical acne product, clindamycin 1.2%/adapalene 0.15%/benzoyl peroxide (BPO) 3.1% gel (CAB) using pooled phase 3 data. METHODS: In two identical phase 3 (N = 183; N = 180), double-blind, 12-week studies, participants aged ≥ 9 years with moderate-to-severe acne were randomized 2:1 to receive once-daily CAB or vehicle gel. Endpoints included ≥ 2-grade reduction from baseline in Evaluator's Global Severity Score and clear/almost clear skin (treatment success) and least-squares mean percent change from baseline in acne lesion counts. Treatment-emergent adverse events (TEAEs) and cutaneous safety/tolerability were evaluated. RESULTS: At week 12, 50.0% of participants achieved treatment success with CAB versus 22.6% with vehicle gel (P < 0.001). CAB resulted in > 70% reductions in inflammatory and noninflammatory lesions at week 12 (77.9% and 73.0%, respectively), which were significantly greater than vehicle (57.9% and 48.2%; P < 0.001, both). Most TEAEs were of mild-moderate severity, and < 3% of CAB-treated participants discontinued study/treatment because of AEs. Transient increases from baseline in scaling, erythema, itching, burning, and stinging were observed with CAB, but resolved back to or near baseline values by week 12. CONCLUSIONS: The innovative fixed-dose, triple-combination clindamycin phosphate 1.2%/adapalene 0.15%/BPO 3.1% gel was efficacious and well tolerated in children, adolescents, and adults with moderate-to-severe acne. Half of participants achieved clear/almost clear skin by 12 weeks, rates not previously seen in clinical studies of other topical acne products. TRIAL REGISTRATION: ClinicalTrials.gov identifier NCT04214639 and NCT04214652.

RESUMEN

BACKGROUND: Acne prevalence may be higher in overweight/obese individuals, potentially due to hormonal, inflammatory, and/or dietary factors. However, the effects of body mass index (BMI) on topical acne treatments are largely unknown. METHODS: Post hoc analyses of changes in inflammatory/noninflammatory lesions and treatment success were conducted using phase 3 data: clindamycin phosphate/benzoyl peroxide (CP/BPO) 1.2%/3.75% gel (NCT01701024); tretinoin 0.05% lotion (NCT02965456 and NCT02932306; pooled); and tazarotene 0.045% lotion (NCT03168321 and NCT03168334; pooled). Data were analyzed by BMI subgroups: <25kg/m2 (underweight-to-normal), 25-<30kg/m2 (overweight), and ≥30kg/m2 (obese). RESULTS: Among participants analyzed (CP/BPO = 495; tretinoin = 1,636; tazarotene = 1,612), ∼20-25% were overweight and 15-20% were obese. At week 12, mean percent changes from baseline in inflammatory lesions were: CP/BPO (overweight: -63.2%, obese: -56.0%); tretinoin (-57.6%, -53.1%); tazarotene (-59.9%, -56.8%). Mean changes in noninflammatory lesions were: CP/BPO (-54.2%, -50.8%); tretinoin (-51.6%, -44.9%); tazarotene (-56.7%, -54.6%). Treatment success rates with active treatment ranged from 16.2% to 33.5% across BMI groups. CONCLUSIONS: CP/BPO 1.2%/3.75% gel, tretinoin 0.05% lotion, and tazarotene 0.045% lotion were all effective in reducing acne lesions by ≥45% in overweight/obese patients with moderate-to-severe acne, comparable to the underweight-to-normal group. Efficacy of these topical acne treatments is not greatly impacted by BMI and may be affected more by the formulation.

RESUMEN

BACKGROUND: Over the past several years, hyperdilute calcium hydroxylapatite (CaHA) has emerged as an effective modality for improving skin quality and managing laxity in the face, arms, hands, neck, décolletage, upper arms, abdomen, buttocks, and upper legs, as well as for treating cellulite and striae. Whereas undiluted CaHA is used to provide volume, hyperdilute CaHA is distributed across a much larger surface area in a more superficial plane to stimulate neocollagenesis and elastin formation over time. The absence of lymphocytic infiltrates and predominance of type 1 collagen in the tissue response to CaHA make hyperdilute CaHA a valuable tool for nonsurgical skin tightening. OBJECTIVES: The aim of this study was to provide practical step-by-step guidance on patient selection, dilution practices, and optimal injection technique to facilitate incorporation of the technique into clinical practice. METHODS: Over the course of 3 regional meetings in the United States, 12 expert physician injectors participated in live webinars as part of a continuing medical education program. RESULTS: The practical guidance in this manuscript is based upon the most frequently requested information by audience members and the information considered critical for success by the authors. CONCLUSIONS: The minimally invasive nature of filler injection results in little downtime, making this treatment particularly appealing. The recommendations presented are consistent with previously published consensus guidelines on hyperdilute CaHA but are intended to serve as "how-to" guidance based on the experience of expert injectors who have successfully treated the face and body.

RESUMEN

Background: As current tazarotene formulations indicated for acne (0.1%) can cause irritation, a new tazarotene 0.045% lotion formu-lation was developed using polymeric emulsion technology. The objective was to assess efficacy, safety, and tolerability of tazarotene 0.045% lotion in patients with moderate-to-severe acne in a pooled analysis of data from two identical phase 3, double-blind, random-ized, vehicle-controlled 12-week clinical studies. Methods: Patients aged ≥9 years with moderate-to-severe acne were randomized (1:1) to tazarotene 0.045% lotion or vehicle lotion applied once daily. Inflammatory and noninflammatory lesion counts and Evaluator's Global Severity Score (EGSS) were assessed. Treatment success was defined as a ≥2-grade improvement in EGSS and a score of 'clear'/'almost clear'. Adverse events (AEs) and cutaneous safety and tolerability were also assessed. Results: In total, 1614 patients (mean age: 20.5 years) were randomized to tazarotene 0.045% lotion (n=799) or vehicle (n=815). At week 12, tazarotene 0.045% lotion demonstrated statistically significant superiority versus vehicle in reducing inflammatory and non-inflammatory lesion counts (least-squares mean percent changes from baseline: inflammatory, -57.9% vs -47.8% [P<0.001]; noninflam-matory, -56.0% vs -42.0% [P<0.001]). Treatment success at week 12 was also greater with tazarotene 0.045% lotion versus vehicle (30.4% vs 17.9%; P<0.001). The most frequent treatment-emergent AEs related to tazarotene treatment were application site pain (5.3%), dryness (3.6%), and exfoliation (2.1%). Conclusions: The new tazarotene 0.045% lotion formulated with polymeric emulsion technology demonstrated statistically signifi-cantly superior efficacy versus vehicle and was well tolerated in pediatric and adult patients with moderate-to-severe acne in this pooled analysis of 2 vehicle-controlled phase 3 studies.

RESUMEN

BACKGROUND: Aesthetic medicine has evolved from targeting individual treatment areas to a global approach of panfacial rejuvenation. HARMONY was the first clinical study to systematically demonstrate positive physical and psychosocial impacts of panfacial treatment. OBJECTIVE: Provide evidence-based guidance on treatment strategies to help maximize outcomes in patients seeking panfacial rejuvenation. MATERIALS AND METHODS: Study sites with the lowest (n = 2) and highest (n = 2) improvements based on FACE-Q Satisfaction with Face Overall scores were analyzed to understand differences in treatment strategy that may contribute to incrementally greater patient satisfaction. RESULTS: The highest scoring sites exhibited greater improvement in all patient-reported outcomes and investigator-assessed measures related to dermal filler treatment compared with the lowest scoring sites. The highest sites favored lateral malar augmentation and used less volume medially versus the lowest sites. In the lower face, the highest sites used greater volumes and more HYC-24L than HYC-24L+. Initial treatment volumes were more conservative at highest than lowest sites; greater volumes were used by highest sites in touch-up treatments. CONCLUSION: Product usage trends common to the highest scoring sites (including injection volume, injection sites, and product selection) may provide guidance on best practices for a panfacial approach to aesthetic treatment to maximize patient satisfaction.

RESUMEN

BACKGROUND: Although commonly practiced, simultaneous onabotulinumtoxinA injections to multiple facial areas have not been investigated in prospective studies. OBJECTIVE: Evaluate safety and efficacy of onabotulinumtoxinA for treatment of forehead lines (FHL) distributed between the frontalis (20 U) and glabellar complex (20 U), with or without simultaneous lateral canthal areas (crow's feet lines [CFL], 24 U) treatment. METHODS: Subjects with moderate to severe FHL were randomized (2:2:1) to onabotulinumtoxinA 40 U, onabotulinumtoxinA 64 U, or placebo. After 180 days, subjects could receive up to 2 additional open-label onabotulinumtoxinA 64 U treatments. RESULTS: The intent-to-treat (ITT) population comprised 787 subjects, and the modified ITT (mITT) population (subjects with psychological impact) comprised 568. After 30 days, onabotulinumtoxinA 40 U and 64 U significantly improved investigator- and subject-assessed FHL severity by at least 2 Facial Wrinkle Scale (FWS) grades in 45.6% and 53.0% of ITT subjects, respectively, versus 0.6% receiving placebo (both, p < .0001). Significantly more mITT subjects receiving onabotulinumtoxinA achieved investigator- and subject-assessed FWS ratings of none/mild versus placebo (p < .0001). OnabotulinumtoxinA was well tolerated. CONCLUSION: OnabotulinumtoxinA distributed between the frontalis and glabellar complex, with or without additional CFL injections, was safe and effective for treatment of moderate to severe FHL.

RESUMEN

BACKGROUND: The popularity of aesthetic procedures in the face has led to greater disparity between treated areas and those that still show evidence of true age. Although many areas of the body often require multiple treatment procedures for optimal rejuvenation, combination therapy for specific areas is not yet well defined. OBJECTIVE: To develop recommendations for the optimal combination and ideal sequence of botulinum toxin (BoNT), hyaluronic acid, calcium hydroxylapatite (CaHA), and microfocused ultrasound with visualization in nonfacial areas across all skin phototypes. METHODS: Fifteen specialists convened under the guidance of a certified moderator. Consensus was defined as approval from 75% to 94% of all participants, whereas agreement of ≥95% denoted a strong consensus. RESULTS: Recommendations have been provided for the neck, décolletage, and hands and include the timing and sequence of specific procedures when used concurrently or over several treatment sessions. Position statements are offered in lieu of consensus for the upper arms, abdomen, buttocks, and knees. CONCLUSION: Nonfacial rejuvenation often requires multiple procedures for optimal results in individuals with significant age-related changes. Further clinical studies are recommended to raise awareness of non-facial indications and provide clinicians with the best evidence for best treatment practices.

RESUMEN

BACKGROUND: Micro-focused ultrasound with visualization has been cleared by the United States Food and Drug Administration to noninvasively lift the eyebrow, lift submental and neck tissue, and improve lines and wrinkles of the décolleté. OBJECTIVE: The objective of this prospective, open-label pilot study was to evaluate the efficacy and safety of patient-specific, customized micro-focused ultrasound with visualization treatment with vertical vectoring to lift and tighten facial and neck tissue. METHODS AND MATERIALS: Subjects 25 to 60 years of age (N=20) with areas of skin laxity on the face and neck were enrolled and treated. A dual depth treatment was administered using a vectored pattern. Subjects were evaluated after 90 days, 180 days, and one year. RESULTS: Overall improvements in Subject Global Aesthetic Improvement Scale and Physician Global Aesthetic Improvement Scale scores were reported by 90 and 100 percent of subjects at 90 and 180 days, respectively, and 95 percent for both measures at one year. Six of 14 evaluable subjects were rated as improved by blinded assessment at one year. Self-reported improvements maintained for up to one year included less sagging (79%), fewer lines and wrinkles (58%), and smoother skin texture (47%). CONCLUSION: Based on these results, treatment with micro-focused ultrasound with visualization with vertical vectoring demonstrated appreciable lifting and tightening of facial and neck tissue resulting in improved Global Aesthetic Improvement Scale scores and a high degree of patient satisfaction for up to one year. ClinicalTrials.gov Identifier: NCT01708512.

RESUMEN

BACKGROUND: The aging process is a complex interplay of intrinsic and extrinsic factors across multiple layers of the face. Accordingly, combining aesthetic interventions targeting different manifestations of aging often leads to better results than single modalities alone. However, no guidelines for a pan-facial approach using multiple interventions have been published to date. OBJECTIVE: To develop consensus recommendations for the optimal combination and ideal sequence of botulinum toxin (BoNT), hyaluronic acid, calcium hydroxylapatite, and microfocused ultrasound with visualization (MFU-V) in persons of all Fitzpatrick skin types. METHODS AND MATERIALS: Fifteen specialists convened under the guidance of a certified moderator. Consensus was defined as approval from 75% to 94% of all participants, whereas agreement of ≥95% denoted a strong consensus. RESULTS: Optimal aesthetic treatment of the face begins with a thorough patient assessment and an individualized treatment plan. Spacing consecutive treatments 1 to 2 weeks apart allows for resolution of side effects and/or to assess results. For same-day treatments, BoNT and fillers may be performed together in either sequence, whereas MFU-V is recommended before injectable agents. CONCLUSION: Expert consensus supports a combination approach using multiple modalities in specific sequence for the safe and effective treatment of the aging face.

RESUMEN

The authors summarized data from a group of physicians with experience using high-dose rate electronic brachytherapy for the treatment of nonmelanoma skin cancer. The data have been published or presented in abstract format at national dermatology and radiation oncology meetings. The data included 1,822 treated lesions from 2009 to 2014 in patients ranging in age from 52 to 104 years. Most lesions were basal cell carcinoma (57%) or squamous cell carcinoma (38%) less than 2cm in size (97%). Median follow-up at the various centers ranged from 4 to 16 months, and results yielded an extremely low recurrence rate of less than one percent. Results show that within the confines of this follow up period, electronic brachytherapy is an effective, convenient, nonsurgical treatment option for patients with nonmelanoma skin cancer with few recurrences and excellent cosmetic results.

RESUMEN

BACKGROUND: Acne scarring remains a stubborn clinical problem. Few treatments have been shown to be definitely effective for this problem. Polymethylmethacrylate (PMMA) microspheres in collagen (ArteFill, Suneva Medical Inc, Santa Barbara, CA) have shown long-term benefit for nasolabial fold treatment. A pilot study has shown benefit for PMMA-collagen in atrophic acne scarring. OBJECTIVE: We sought to demonstrate the safety and effectiveness of PMMA-collagen for acne scarring in a controlled, blinded trial. METHODS: Subjects with at least 4 moderate to severe rolling, atrophic scars randomly received PMMA-collagen or saline injections. Subjects underwent up to 2 injection sessions and were followed up for 6 months. Efficacy was assessed using a validated rating scale for each scar. RESULTS: In all, 147 subjects underwent injections. Success was achieved by 64% of those treated with PMMA-collagen compared with 33% of control subjects (P = .0005). The treatment showed excellent safety with generally mild, reversible adverse events. No significant differences in efficacy or safety were noted between genders, for darker skin types, or in older age groups. LIMITATIONS: Subjects were followed up for only 6 months. CONCLUSION: PMMA-collagen demonstrates substantial effectiveness in the treatment of atrophic acne scars of the face while maintaining an excellent safety profile. Further follow-up should be undertaken to demonstrate longer-term benefit and safety.

RESUMEN

BACKGROUND: A device to assist in the delivery of dermal filler may achieve reductions in patient discomfort and adverse events, as well physician fatigue. It may also increase the accuracy of material placement. OBJECTIVES: The authors assess the safety and performance of the Artiste Assisted Injection System (Nordson Micromedics, St Paul, Minnesota) in normal therapeutic use compared with the standard manual administration of dermal fillers. METHODS: At 3 study sites, a total of 52 patients (48 women and 4 men) received bilateral full-correction injections of dermal fillers into randomized nasolabial folds (NLF). Injection into 1 NLF was made via Artiste, and injection into the other NLF was made via manual delivery. Immediately posttreatment and through 29 days, physician investigators, patients, and blinded evaluators recorded treatment durations and volumes, evaluated designated posttreatment characteristics using questionnaires, and documented adverse events (AE) and differences in cosmetic effects. RESULTS: Mean filler volume was 1.25 mL for the Artiste-treated NLF and 1.29 mL for manually treated NLF. One investigator used significantly less volume with Artiste than with manual injection (0.95 mL vs 1.12 mL; P = .001). Blinded evaluators rated Wrinkle Severity Rating Scale (WSRS) results as "identical" in 81% of patients. Investigator questionnaires showed a clear and statistically significant preference for Artiste over manual injection in all parameters (P < .001). CONCLUSIONS: The Artiste device is a viable option for physicians seeking a continuous-flow, injection-assisted device for ease of treatment, better accuracy, and improved results.

RESUMEN

BACKGROUND: Injectable poly-L-lactic acid (PLLA) is indicated in the United States for use in immune-competent patients for correction of shallow-to-deep nasolabial fold contour deficiencies and other facial wrinkles in which a deep dermal grid pattern injection technique is appropriate. It is also indicated for restoration and/or correction of signs of lipoatrophy in patients with human immunodeficiency virus. OBJECTIVE: The authors examine the efficacy of injectable PLLA for correction of nasolabial fold wrinkles, based on Investigator Global Evaluations (IGE). METHODS: A randomized, multicenter, subject-blinded, parallel-group study compared injectable PLLA versus human collagen for correction of nasolabial fold wrinkles for 13 months after up to four treatments (intent-to-treat population, 233). Injectable PLLA-treated subjects were followed up for an additional 12 months (total, 25 months) after the final treatment session. Efficacy was also assessed through secondary IGE for improvement, which is the subject of this report. RESULTS: IGE reports of improvement were significantly greater in subjects who received injectable PLLA versus those who received human collagen (p < .001). Overall improvement with injectable PLLA was 100% three weeks after the final treatment, remaining above 85% through month 25. Overall IGE of improvement with human collagen declined from 94.0% at week three to 6.0% at month 13. Both treatment groups had similar safety profiles. CONCLUSIONS: IGE of improvement were significantly greater with injectable PLLA treatment than with human collagen treatment at all time points following the last treatment. Injectable PLLA treatment continued to show a beneficial effect for up to 25 months.

RESUMEN

BACKGROUND: This is a report of the secondary endpoints, Subject Global Evaluation (overall improvement) and Subject Satisfaction scores, from a study designed to examine the efficacy of injectable poly-L-lactic acid for the correction of nasolabial fold wrinkles over 25 months. METHODS: A randomized, subject-blinded, parallel-group, multicenter clinical study was conducted to compare the effects of injectable poly-L-lactic acid with those of human collagen for the treatment of nasolabial fold wrinkles at 13 months following the last treatment. Injectable poly-L-lactic acid-treated subjects were followed for 25 months. RESULTS: From month 3 through month 13 following the last treatment, injectable poly-L-lactic acid-treated subjects (n = 116) reported significantly higher Subject Global Evaluation scores compared with human collagen-treated subjects (n = 117; p < 0.001). Overall Subject Global Evaluation scores for injectable poly-L-lactic acid-treated subjects were 99 percent at week 3, 91 percent at month 13, and 81 percent at month 25 (all times following the last treatment). In contrast, for human collagen-treated subjects, overall Subject Global Evaluation scores declined by 84 percent, from 96 percent at week 3 to 15 percent at month 13. Subject Satisfaction scores were significantly different (p < 0.01) between treatment groups beginning week 3 and continuing through month 13. Overall Subject Satisfaction scores were maintained for over 80 percent of injectable poly-l-lactic acid-treated subjects (n = 106) at month 25 after the last treatment. CONCLUSIONS: Treatment of nasolabial fold wrinkles with injectable poly-l-lactic acid resulted in statistically significantly higher Subject Global Evaluation and Subject Satisfaction scores compared with human collagen at 13 months. Injectable poly-l-lactic acid-treated subjects maintained improvements for up to 25 months after treatment.

RESUMEN

Actinic keratosis (AK), the initial lesion in a disease continuum that may progress to squamous cell carcinoma, often begins with ultraviolet B light-induced photo damage and increases in prevalence with age. Topical 5-fluorouracil (5-FU) for the treatment of widespread multiple AK lesions has cure rates of more than 90 percent. The associated skin irritation, however, may lead patients to prematurely discontinue treatment. To improve treatment efficacy and tolerability, 5-FU cream 0.5%, a novel Microsponge(®)-based formulation, was developed. In the elderly population, 5-FU cream 0.5% may be preferable because of its convenient (once daily) administration and its lower potential for irritation and systemic absorption, which may impact adherence to therapy and, thus, possibly increase cure rates.
