A Multicenter Pivotal Study to Evaluate Tissue Stabilized-Guided Subcision Using the Cellfina Device for the Treatment of Cellulite With 3-Year Follow-Up.

BACKGROUND: Cellulite is a common female cosmetic concern for which no single treatment option had been proven effective over the long term. A novel tissue stabilized-guided subsicion system (TS-GS system) has demonstrated significant reduction in the appearance of cellulite after treatment. OBJECTIVE: The objective of this extended follow-up period was to assess the effectiveness of TS-GS out to 3 years after initial treatment. PATIENTS AND METHODS: After completing an open-label, multicenter, pivotal study, 45 subjects were followed for an extended period of up to 3 years after receiving a single treatment using the TS-GS system. Treatment areas were photographed prior to the procedure and at multiple time points post-treatment throughout the 3 years. In this open-label study, subjects served as their own controls. Effectiveness was assessed based on blinded independent physician panel assessments of improvement from baseline using a cellulite severity scale. Subject aesthetic improvement and patient-reported satisfaction were also collected. RESULTS: The results of this trial supported Food and Drug Administration clearance of the device for the long-term reduction in the appearance of cellulite following TS-GS. CONCLUSION: These data further demonstrate the safety and efficacy of this treatment with no reduction in treatment benefits out to 3 years.

Safety of IncobotulinumtoxinA in the Treatment of Facial Lines: Results From a Pooled Analysis of Randomized, Prospective, Controlled Clinical Studies.

BACKGROUND: The safety and efficacy of incobotulinumtoxinA in aesthetics has been established in multiple studies. Although individual studies have been reported, a combined assessment of incobotulinumtoxinA safety across studies is not available. OBJECTIVE: To assess the frequency of adverse events (AEs) across prospective incobotulinumtoxinA studies in aesthetics. MATERIALS AND METHODS: Safety data were assessed from 9 placebo-controlled or active-controlled single-dose studies on glabellar frown lines (GFL), crow's feet (CF), and upper facial lines (UFL). Analyses by treatment cycle included 4 repeat-dose studies on GFL and UFL. RESULTS: One thousand three hundred seventy-seven subjects received incobotulinumtoxinA (GFL, n = 1,189; CF, n = 83; UFL, n = 105) in single-dose studies (placebo-controlled studies: incobotulinumtoxinA, n = 866; placebo, n = 395). Over 1,000 subjects received incobotulinumtoxinA in repeat-dose studies (GFL, n = 880; UFL, n = 290). In placebo-controlled single-dose studies, incidences of treatment-related AEs ranged from 5.4% (GFL) to 22.9% (UFL). The most frequent treatment-related AE in single-dose studies was headache (GFL, 4.8%; UFL, 11.4%). In repeat-dose studies, incidence of AEs was highest during cycle 1 (GFL, 8.9%; UFL, 17.2%) and decreased across treatment cycles. No serious treatment-related AEs were observed. CONCLUSION: Results confirm the favorable safety and tolerability of incobotulinumtoxinA. The frequency of treatment-related AEs was low and may decrease with subsequent treatments.

A Multicenter Controlled Study to Evaluate Multiple Treatments With Nonthermal Focused Ultrasound for Noninvasive Fat Reduction.

BACKGROUND: Demand for nonsurgical esthetic body procedures has led to the development of noninvasive techniques for reducing localized subcutaneous adipose tissue. OBJECTIVE: This study assessed multiple treatments with nonthermal focused ultrasound for noninvasive abdominal treatment of excess fat deposits. MATERIALS AND METHODS: Subjects were randomly assigned to Group 1 for a 4-week control phase before undergoing 3 abdominal fat reduction treatments, at 2-week intervals, or to Group 2 for immediate treatment. Weight, abdominal circumference, tolerability to treatment, subject satisfaction, and adverse events were recorded. RESULTS: Weight remained stable in the 126 participants. Mean reduction in midline circumference was 2.5 ± 2.1 cm in the Group 1 and 3.5 ± 2.7 cm in the Group 2 at Week 22. The effect of multiple treatments was cumulative with a steady decrease in abdominal circumferences during the study. Erythema was observed in 28% of treatments but was mild and transient in nature. Subjects tolerated the treatments well and were satisfied with treatment outcome. CONCLUSION: The study demonstrated the efficacy and safety of multiple nonthermal focused ultrasound treatments of excess abdominal fat deposits. Although the remodeling effect is minor compared with traditional surgical procedures, successive focused ultrasound treatments significantly reduced treatment area circumference, while avoiding invasive techniques and their associated disadvantages.

Bimatoprost 0.03% for the Treatment of Eyebrow Hypotrichosis.

BACKGROUND: Eyebrow loss may have substantial negative functional and social consequences. OBJECTIVE: Evaluate the safety and efficacy of bimatoprost 0.03% in subjects with eyebrow hypotrichosis. METHODS: This multicenter, double-masked study randomized adult females or males with eyebrow hypotrichosis to receive bimatoprost 0.03% twice (BID) or once daily (QD) or vehicle BID for 7 months. Primary endpoint was overall eyebrow fullness at Month 7. Secondary endpoints included eyebrow fullness (mm), darkness (intensity units), and subject satisfaction with treatment. Safety was also assessed. RESULTS: At Month 7, the proportion of subjects with improvement was significantly higher in bimatoprost groups versus vehicle (both, p < .001). Improvements occurred in both bimatoprost groups versus vehicle after Month 1 and continued through follow-up; eyebrow fullness and darkness improved as early as Months 2 and 1, respectively (both, p < .001). Greater satisfaction was reported with bimatoprost versus vehicle at Month 2 and all subsequent time points. Overall, 38.1%, 42.4%, and 35.5% of subjects in the bimatoprost BID, QD, and vehicle groups, respectively, experienced ≥1 treatment-emergent adverse event (TEAE). Most frequent TEAEs were similar across groups. No skin or iris hyperpigmentation or conjunctival hyperemia occurred. CONCLUSION: Bimatoprost 0.03% BID and QD is safe, well tolerated, and effective for eyebrow hypotrichosis.

A Randomized, Double-Blind Trial to Investigate the Equivalence of IncobotulinumtoxinA and OnabotulinumtoxinA for Glabellar Frown Lines.

BACKGROUND: IncobotulinumtoxinA and onabotulinumtoxinA are indicated for the temporary improvement in the appearance of glabellar frown lines (GFL). This is the first randomized direct comparator study to date, at the Food and Drug Administration-recommended dose of 20 units (U), for the treatment of GFL. OBJECTIVE: To investigate the dose equivalence of incobotulinumtoxinA (20 U) and onabotulinumtoxinA (20 U) for the treatment of moderate-to-severe GFL. MATERIALS AND METHODS: Prospective, randomized (1:1), double-blinded, parallel-group study in 250 females (18-50 years), employing a single treatment with incobotulinumtoxinA or onabotulinumtoxinA, followed by a 4-month observational period. RESULTS: At the primary efficacy endpoint (1 month after treatment), incobotulinumtoxinA was equivalent to onabotulinumtoxinA in the treatment of GFL at the 20 U dose within the prespecified ± 15% margin of equivalence. Efficacy remained similar between treatment groups through 4 months after treatment as assessed by the independent masked panel and the masked treating physicians. Patient satisfaction ratings were similar between groups and favorable (>90%) throughout. Both treatments were well tolerated. CONCLUSION: Equivalence was demonstrated at the primary endpoint between incobotulinumtoxinA and onabotulinumtoxinA in the treatment of GFL at the 20 U dose at 1 month. Similar efficacy and tolerability profiles were observed through 4 months after treatment.

Multicenter pivotal study of vacuum-assisted precise tissue release for the treatment of cellulite.

BACKGROUND: Cellulite refers to the dimpled appearance of skin occurring where the dermis is tethered by subcutaneous fibrous septa arranged perpendicularly to the skin surface. OBJECTIVE: To demonstrate the safety and efficacy of a new system for vacuum-assisted precise tissue release for the treatment of cellulite. MATERIALS AND METHODS: Adult women with moderate to severe cellulite (N = 55) underwent a single treatment. Post-treatment assessments were performed after 3 and 14 days; 1, 3, and 6 months; and at 1 year. Outcome measures included blinded assessments of subject photographs, a validated Cellulite Severity Scale (CSS), and the Global Aesthetic Improvement Scale. Subject satisfaction and pain ratings were also recorded. RESULTS: The mean baseline CSS score of 3.4 decreased to 1.3 at 3 months (p < .0001) and 1.4 at 1 year (p < .0001), with 47 subjects (93%) having ≥1-point improvements. Subject satisfaction was 85% at 3 months and 94% at 1 year. Transient treatment-related adverse events were mild in severity. CONCLUSION: This study demonstrates the safety, efficacy, and subject satisfaction with vacuum-assisted precise tissue release in the treatment of cellulite. There was no reduction in treatment benefits for up to 1 year. These results supported the Food and Drug Administration clearance of the device for the long-term reduction in the appearance of cellulite.

Effects of OnabotulinumtoxinA treatment for crow's feet lines on patient-reported outcomes.

BACKGROUND: Although millions of aesthetic procedures are performed annually, few patient-reported outcome (PRO) measures have been used in this setting. OBJECTIVE: To evaluate the impact of onabotulinumtoxinA treatment for crow's feet lines (CFL) on relevant psychological variables and self-perception of age/appearance in subgroup populations. MATERIALS AND METHODS: Facial Lines Outcomes (FLO-11) Questionnaire, Self-Perception of Age (SPA), and Subject Global Assessment of Change in CFL (SGA-CFL) were PRO measures administered in 2 Phase 3, double-blind placebo-controlled trials for the treatment of CFL alone or CFL/glabellar lines (GL). Patient-reported outcome measures were analyzed by subgroups (age, gender, and baseline CFL severity). Subject satisfaction with appearance was also analyzed. RESULTS: Most subgroups receiving onabotulinumtoxinA demonstrated significant improvements in psychological impact (FLO-11 Items 2, 5, and 8) versus placebo at Day 30 (p ≤ .05). OnabotulinumtoxinA-treated subjects consistently rated themselves as looking younger on SPA versus placebo in all subgroups at Day 30 (p ≤ .05) and showed significant improvements in CFL appearance versus placebo at all time points on SGA-CFL. Overall, subjects were satisfied with their appearance. CONCLUSION: OnabotulinumtoxinA-treated subjects experienced significant improvements in perceived appearance, attractiveness, tiredness, age, and satisfaction versus placebo. Subjects treated for CFL and GL experienced even greater effects.

Efficacy of incobotulinumtoxinA for treatment of glabellar frown lines: a post hoc pooled analysis of 2 randomized, placebo-controlled, phase 3 trials.

BACKGROUND: Botulinum neurotoxin type A trials in aesthetic indications have used differing efficacy parameters and responder definitions. OBJECTIVE: To analyze the treatment efficacy and duration of incobotulinumtoxinA for glabellar frown lines using pooled data from 2 large, Phase 3, placebo-controlled trials, and end points similar to those used in previous botulinum neurotoxin type A studies. MATERIALS AND METHODS: IncobotulinumtoxinA and placebo groups comprised 366 and 181 subjects, respectively. The efficacy of a single 20-U treatment of incobotulinumtoxinA or placebo was evaluated by investigator-assessed and subject-assessed responder rates (≥ 1-point improvement from baseline), mean score, and mean change from the baseline glabellar frown line severity score. RESULTS: At all follow-up visits, responder rates and mean change from the baseline score (investigator-assessed and subject-assessed) were significantly greater for incobotulinumtoxinA versus placebo (p < .0001). The maximum investigator-assessed responder rate (93.1%) was achieved at Day 30 after treatment, when the mean improvement on the 4-point facial wrinkle scale peaked at 1.88. Treatment effect declined over time but the investigator-assessed responder rate was 45.7% at the end of the study. CONCLUSION: Superiority of incobotulinumtoxinA over placebo for treating glabellar frown lines was confirmed. IncobotulinumtoxinA achieved a maximum responder rate of 93.1% and a long duration of treatment effect: 45.7% of subjects showed efficacy at 120 days.
