Clinical Benefits of DaxibotulinumtoxinA for Injection: Beyond Glabellar Line Effacement?

BACKGROUND: Botulinum toxin type A (BoNTA) is standard of care for glabellar lines ameliorization. DaxibotulinumtoxinA for Injection (DAXI) is a new BoNTA with a unique formulation representing the latest advancement in BoNTA technology. There is an unmet need for patients to understand the full potential of BoNTA treatment and new technologies. OBJECTIVE: To update clinical data supporting the use of DAXI for glabellar lines within the context of clinical experience. MATERIALS AND METHODS: A narrative review of the literature and summary of clinical experience with DAXI. RESULTS: The DAXI clinical trial program reflects clinical experience post-FDA approval, with DAXI demonstrating rapid onset, high patient response rates, and extended treatment duration versus conventional BoNTAs. Clinical observations suggest that DAXI has limited diffusion from the injection site, enabling more localized control of muscle activity and greater improvements in wrinkle severity. DAXI enables practitioners to exert greater finesse in their injections and in predicting changes to eyebrow shape and position and achieve improvement in skin quality. CONCLUSION: Advances in BoNTA technology can provide patients with greater options for treatment outcomes. The potential for enhanced localized effects with DAXI may contribute to more precise and targeted effects on muscle activity and additional aesthetic benefits to patients.

Treatment of Upper Facial Lines With DaxibotulinumtoxinA for Injection: Results From an Open-Label Phase 2 Study.

BACKGROUND: Simultaneous treatment of moderate-to-severe upper facial lines is reflective of real-world clinical practice. OBJECTIVE: To evaluate the efficacy and safety of daxibotulinumtoxinA-lanm for injection (DAXI) for simultaneous treatment of glabellar, forehead, and lateral canthal (LC) lines. METHODS: In this open-label, single-arm Phase 2 study, patients (48 enrolled, 94% completed, follow-up 24-36 weeks) received DAXI 40U (glabellar), 32U (forehead), and 48U (LC) lines. Key efficacy endpoints: percentages of patients achieving none/mild wrinkle severity (investigator-rated) for each upper facial line scale at Week 4. RESULTS: At Week 4, most patients achieved none/mild wrinkle severity (investigator-rated): glabellar (96%), forehead (96%), and LC (92%). Median times to loss of none/mild response (investigator- and patient-rated) among all patients were: 24.6 (glabellar), 20.9 (forehead), and 24.9 (LC) weeks; and 25.0, 24.0, and 28.1 weeks, respectively, among Week-4 responders. At Week 4, most patients reported improvements (Global Aesthetic Improvement Scale: 96%-98%) and high satisfaction rates (85%-98%). Five patients experienced treatment-related adverse events: injection-site erythema (3 patients/7 events), facial discomfort (2 patients/2 events), and headache (1 patient/1 event). No patients experienced eyebrow or eyelid ptosis. CONCLUSION: Simultaneous treatment of upper facial lines with DAXI was well tolerated and demonstrated high response rates, extended duration, and high patient satisfaction.

Improved Patient Satisfaction With Skin After Treatment of Cheek Skin Roughness and Fine Lines With VYC-12L: Participant-Reported Outcomes From a Prospective, Randomized Study.

BACKGROUND: VYC-12L is a hyaluronic acid filler to improve skin quality. A prospective study showed safety and effectiveness of VYC-12L for improving cheek skin smoothness and fine lines. OBJECTIVES: To report participant-reported outcomes, subgroup analyses, and physician experience from the prospective study. METHODS: Adults with moderate to severe Allergan Cheek Skin Smoothness (ACSS) scale scores were randomized 2:1 to VYC-12L or control (no treatment with optional treatment). Participant assessments included FACE-Q Satisfaction With Skin, FACE-Q Appraisal of Lines, natural look and feel, the Global Aesthetic Improvement Scale (GAIS), and safety. Subgroup analyses examined ACSS responder rate (≥1-grade improvement from baseline to 1 month). RESULTS: FACE-Q Satisfaction With Skin overall mean scores improved from baseline to 1 month posttreatment by 32.0 and 1.4 in the VYC-12L and control groups, respectively. FACE-Q Appraisal of Lines overall mean scores improved from baseline to 1 month posttreatment by 23.3 and 0.4 in VYC-12L and control, respectively. Treated participants had high median scores (≥9.0) of natural look and feel of their cheek skin. GAIS responder rate was high at Month 1 (85.5%; 95% CI, 79.3%-91.7%) and through Month 6 (83.1%; 95% CI, 76.5%-89.7%). Mean participant-rated pain scores were low (<3). The most common injection site reactions were redness, swelling, and lumps/bumps; most resolved within 3 days. Subgroup analyses showed significant differences in ACSS responder rate between VYC-12L and control groups 1 month posttreatment. Physician injectors reported that VYC-12L was easily injected at the superficial skin and integrated quickly. CONCLUSIONS: VYC-12L treatment produced significant improvements in satisfaction with skin and cheek skin smoothness, as measured by participant-reported outcome measures.

Efficacy and Safety of Tapencarium (RZL-012) in Submental Fat Reduction.

BACKGROUND: Tapencarium (RZL-012) (5-(3.6-dibromo-9H-carbazol-9-yl)-N, N, N-trimethylpentan-1-aminium chloride) is a novel injectable synthetic molecule with cytolytic properties, capable of reducing subcutaneous fat volume. OBJECTIVES: The goal of this 3-armed, randomized, double-blind, placebo-controlled phase 2b study was to determine the safety and efficacy of low- and high-dose RZL-012 vs placebo on submental fat (SMF) reduction. METHODS: Patients (n = 151, age 18-65 years) with excess SMF received a single treatment session of RZL-012 or placebo in the submental area, after which they were monitored for 84 days. SMF was assessed at baseline and after dosing with newly developed scales, namely the Clinician Chin Assessment Tool (C-CAT) and Subject Chin Assessment Tool (S-CAT). SMF was also assessed by magnetic resonance imaging (MRI) at screening and on Day 84 after treatment. RESULTS: The proportion of patients who had a 1-grade or 2-grade improvement in C-CAT and/or S-CAT on Day 84 vs baseline was significantly higher in the high-dose RZL-012 group vs the placebo group (P < .002). The relative percentage reduction in MRI-measured SMF volume (Day 84 vs screening) was significantly greater in the high-dose RZL-012 group vs the low-dose RZL-012 or the placebo group (P < .0001). Local injection site reactions were the most common adverse events (AEs). CONCLUSIONS: A single administration of RZL-012 into SMF resulted in significant improvement in submental appearance as assessed by clinicians, patients, and MRI. From a safety perspective, there were no serious AEs and no clinically significant changes in vital signs or laboratory tests over the course of the study.

Efficacy and Safety of a New Resilient Hyaluronic Acid Filler in the Correction of Moderate-to-Severe Dynamic Perioral Rhytides: A 52-Week Prospective, Multicenter, Controlled, Randomized, Evaluator-Blinded Study.

BACKGROUND: The perioral region is highly mobile and subject to multifactorial changes during aging. Resilient Hyaluronic Acid Redensity (RHAR), an RHA filler, was developed with the aim of optimizing outcomes in dynamic facial areas. OBJECTIVE: This randomized, blinded, multicenter clinical study aimed to demonstrate superiority of RHAR over no-treatment control for correction of moderate-to-severe dynamic perioral rhytides. MATERIALS AND METHODS: Blinded live evaluator assessments of efficacy included improvement in perioral rhytides severity using a proprietary scale (Perioral Rhytids Severity Rating Scale [PR-SRS]) and the Global Aesthetic Improvement Scale. Subjects self-assessed their results with FACE-Q, a validated patient-reported outcome measure, and satisfaction scales. Safety was monitored throughout the study based on common treatment responses (CTRs) and adverse events (AEs). RESULTS: The primary efficacy end point was achieved, with the treatment group showing statistically significant superiority over the control group at Week 8 (80.7% vs 7.8% responder rate by PR-SRS, p < .0001). Most patients (66%) were still responders at Week 52 (study completion). Most AEs were CTRs after perioral injection of a dermal filler, and none was a clinically significant treatment-related AE. CONCLUSION: Resilient Hyaluronic Acid Redensity is effective and safe for the correction of dynamic perioral rhytides in all Fitzpatrick phototypes, with marked durability.

Multimodal Facial Aesthetic Treatment on the Appearance of Aging, Social Confidence, and Psychological Well-being: HARMONY Study.

BACKGROUND: A global approach to facial rejuvenation involves multiple treatment modalities. OBJECTIVES: The aim of this study was to evaluate the impact of multimodal facial aesthetic treatment on self-reported psychological and social outcomes. METHODS: HARMONY, a prospective, multicenter, 4-month study, enrolled patients aged 35 to 65 years to receive on-label treatment with a combination of hyaluronic fillers (VYC-20L, HYC-24L, and/or HYC-24L+), onabotulinumtoxinA, and bimatoprost. Fillers were injected on Day 1, with touch-ups performed on Day 14. OnabotulinumtoxinA was injected at Month 3 into glabellar lines and/or crow's feet lines. Patients applied bimatoprost to eyelashes once daily for 17 weeks. Mean change from baseline on FACE-Q Psychological Well-being and Social Confidence Scales, FACE-Q Aging Appearance Appraisal Scale, and FACE-Q Age Appraisal Visual Analog Scale were assessed. RESULTS: Of 100 patients treated, 93 were evaluated at 4 months posttreatment. Significant improvement vs baseline was observed on the FACE-Q Scales for Psychological Well-being (mean change, -19.9; P < 0.00001), Social Confidence (mean change, -18.2; P < 0.00001), and Aging Appearance (mean change, -28.5; P < 0.0001). On average, patients' self-assessed age was 0.1 years older than actual age at baseline and 4.5 years younger at Month 4 (P < 0.001 vs baseline). Forty-two patients experienced adverse events, all mild to moderate. CONCLUSIONS: Multimodal, full facial aesthetic treatment improves patients' self-reported psychological well-being, social confidence, aging appearance, and perceptions of chronologic age.

A Multicenter Study to Evaluate Subject Satisfaction With Two Treatments of AbobotulinumtoxinA a Year in the Glabellar Lines.

BACKGROUND: Real-world re-treatment intervals for botulinum toxins vary, but most subjects receive treatment less frequently than the manufacturer-recommended minimum intervals. In subjects receiving treatment with AbobotulinumtoxinA (ABO) less frequently, high levels of satisfaction and psychosocial improvements in well-being, self-confidence, and quality of life are observed. OBJECTIVE: To evaluate subject satisfaction with a twice yearly re-treatment schedule. METHODS AND MATERIALS: This open-label, multicenter, interventional study evaluated subject satisfaction following injections of ABO 50 U in the glabellar lines at baseline and 6 months. The primary end point was subject satisfaction at 12 months. Secondary endpoints included subject satisfaction, FACE-Q scales, and glabellar line severity scale (GLSS). RESULTS: Ninety-five percent of the 120 subjects were "highly satisfied" or "satisfied" with their treatment outcomes at 12 months. FACE-Q total scores suggested that subjects were less bothered by glabellar lines and felt better about their facial appearance with each treatment versus baseline. Approximately half of subjects had ≥1-grade improvement from baseline in GLSS at 12 months. Median onset of effect was 2 days. CONCLUSION: The majority of subjects (95%) were satisfied with ABO treatment every 6 months; results were supported by high subject satisfaction, long duration, rapid onset, natural-looking results, and overall psychological wellness and safety.

The First of Two One-Year, Multicenter, Open-Label, Repeat-Dose, Phase II Safety Studies of PrabotulinumtoxinA for the Treatment of Moderate to Severe Glabellar Lines in Adult Patients.

BACKGROUND: PrabotulinumtoxinA is a 900-kDa botulinum toxin type A produced by Clostridium botulinum. OBJECTIVES: The authors sought to investigate the safety of prabotulinumtoxinA for treatment of glabellar lines. METHODS: This was a multicenter, open-label, repeat-dose, 1-year phase II safety study. Adults with moderate to severe glabellar lines at maximum frown, as assessed by the investigator on the validated 4-point photonumeric Glabellar Line Scale (0 = no lines, 1 = mild, 2 = moderate, 3 = severe), were enrolled. On day 0, patients received an initial treatment of 20 U prabotulinumtoxinA (4 U/0.1 mL freeze-dried formulation injected into 5 target glabellar sites). On and after day 90, patients received a repeat treatment (RT) if their Glabellar Line Scale score was ≥2 at maximum frown by investigator assessment. Safety was evaluated throughout the study. RESULTS: The 352 study patients received a median total dose of 60 U, that is, 3 treatments per year. Fifty-one patients (14.5%) experienced adverse events (AEs) assessed as possibly study drug related; 11.1% experienced study drug-related AEs after the initial treatment. With each RT, progressively lower percentages of patients experienced study drug-related AEs. Six patients (1.7%) experienced study drug-related AEs of special interest: 3 eyelid ptosis (0.9%), 2 speech disorder (0.6%), and 1 blepharospasm (0.3%). Seven patients (2.0%) experienced serious AEs; none were study drug related. Of the 2393 samples tested, 2 patients (0.6%) tested positive for antibotulinum toxin antibodies at a single postbaseline visit. CONCLUSIONS: The safety of RTs of 20 U of prabotulinumtoxinA for moderate to severe glabellar lines was first established in this early phase II study based on a broad range of outcomes.

DaxibotulinumtoxinA for Injection has a prolonged duration of response in the treatment of glabellar lines: Pooled data from two multicenter, randomized, double-blind, placebo-controlled, phase 3 studies (SAKURA 1 and SAKURA 2).

BACKGROUND: DaxibotulinumtoxinA for Injection (DAXI) is a novel botulinum toxin type A in clinical development. Phase 2 data have shown it offers a more prolonged duration of response than onabotulinumtoxinA. OBJECTIVE: To further evaluate the efficacy, duration of response, and safety of 40 U DAXI compared with placebo in the treatment of glabellar lines. METHODS: Two identical, multicenter, randomized, double-blind, placebo-controlled, phase 3 studies were performed (NCT03014622 and NCT03014635 on www.clinicaltrials.gov). Participants with moderate or severe glabellar lines were randomly assigned (2:1) to receive 40 U DAXI or placebo into the corrugator/procerus muscles. Glabellar line severity was assessed by investigators and participants for up to 36 weeks (≥24 weeks). RESULTS: Among 609 participants enrolled (405 DAXI, 204 placebo), 92% completed. DAXI was significantly more effective than placebo in reducing glabellar line severity and maintained none or mild glabellar line severity for a median of 24.0 weeks. It was also generally well tolerated-treatment-related adverse effects were most commonly headache (6.4% vs 2.0%) and injection site pain (3.7% vs 3.9%). LIMITATIONS: The study population was predominantly female and white and received only a single treatment. CONCLUSIONS: DAXI offers a prolonged duration of response for glabellar line reduction and is well tolerated.

Efficacy and Safety of Two Resilient Hyaluronic Acid Fillers in the Treatment of Moderate-to-Severe Nasolabial Folds: A 64-Week, Prospective, Multicenter, Controlled, Randomized, Double-Blinded, and Within-Subject Study.

BACKGROUND: A range of monophasic dermal fillers made of high-molecular-weight hyaluronic acid (HA) chains with reduced cross-linking was developed for aesthetic procedures. OBJECTIVE: The efficacy, durability, and safety of 2 of these resilient HA (RHA) fillers, and their noninferiority to an effective HA comparator available in the United States, were tested in the treatment of dynamic facial wrinkles. METHODS: A 15-month, prospective, multicenter, active-controlled, randomized, double-blinded, split-face clinical trial was carried out on 174 subjects presenting moderate-to-severe bilateral nasolabial folds (NLFs). Assessed parameters included improvement on a proprietary Wrinkle Severity Rating Scale (WSRS) and Global Aesthetic Improvement Scale, according to Blind Live Evaluators, subjects, and treating investigators. Self-perception was evaluated with FACE-Q and satisfaction scales. RESULTS: The per-protocol populations included 67 and 62 subjects of all Fitzpatrick skin-phototypes, in the 2 comparison groups. Significant improvement of mean WSRS scores and associated responder rates established the noninferiority of RHA fillers to their comparator, over 15 months. Aesthetic improvement and subject satisfaction were durably high, with no meaningful differences between the fillers. Treatments were safe and well tolerated. CONCLUSION: The 2 RHA fillers are at least equivalent to a well-established comparator for the correction of NLF in subjects of diverse skin-phototypes.

Maximizing Panfacial Aesthetic Outcomes: Findings and Recommendations From the HARMONY Study.

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.

Re-examining the Optimal Use of Neuromodulators and the Changing Landscape: A Consensus Panel Update

Since initial US Food and Drug Administration approval of botulinum toxin type A (BoNT-A) for aesthetic use in 2002, clinical evidence and experience with BoNT-A and understanding of facial anatomy have greatly increased, leading to rapid advances in treatment planning and implementation. BoNT-A use has expanded from the upper face to the midface, lower face, and neck, so that BoNT-A injection is the most common cosmetic procedure worldwide. Trends in facial aesthetics reflect growing patient diversity with respect to age, gender, and ethnicity. In October 2019, a multidisciplinary panel of 6 experts in minimally invasive injectable procedures in the specialties of dermatology and plastic surgery convened at the 2019 American Society for Dermatologic Surgery (ASDS) meeting in Chicago, IL. Their goal was to discuss recent advances in BoNT-A use in facial aesthetics, including implications of the introduction of new agents in light of an evolving patient population.

Recommendations for Dermatology Office Reopening in the Era of COVID-19.

The COVID-19 pandemic, originating in Wuhan, China, has become a major public health and economic challenge for countries around the world. As of May 08, 2020, there are over 3 million COVID-19 cases, and 250,000 COVID-19- associated deaths in 215 countries. As more data is collected, updated infection control measures are continuously released and published by government, public health authorities, and physician specialty associations. Across the globe, dermatological practices have had to limit their operations to varying degrees to facilitate disease control, but as the pandemic subsides, they will broaden their operations. In light of the uncertainty surrounding safe and effective practice of medical and aesthetic dermatology in the era of COVID-19, fourteen international experts in the field contributed to recommendations for effective infection control protocols and practice management modifications. While guidance from the World Health Organization and local public health officials comes first, these recommendations are crafted as a starting point for dermatologists worldwide to commence either reopening their doors to patients or expanding available service offerings. This can help ensure that patients receive needed care in the short term and improve long term practice viability. J Drugs Dermatol. 2020;19(7):e-1-e-9. doi:10.36849/JDD.2020.5293.

A Consensus on Minimizing the Risk of Hyaluronic Acid Embolic Visual Loss and Suggestions for Immediate Bedside Management.

BACKGROUND: Hyaluronic acid fillers have a satisfactory safety profile. However, adverse reactions do occur, and rarely intravascular injection may lead to blindness. Currently there is no internationally recognized consensus on the prevention or management of blindness from hyaluronic acid filler. OBJECTIVES: The authors sought to give guidance on how to minimize the risk and optimize the management of this rare but catastrophic adverse reaction. METHODS: A multinational group of experts in cosmetic injectables from multiple disciplines convened to review current best practice and develop updated consensus recommendations for prevention and bedside intervention if visual loss occurs after cosmetic injection of hyaluronic acid filler. RESULTS: The consensus group provided specific recommendations focusing on the consenting process, prevention, and early management of visual impairment related to intravascular hyaluronic acid filler injection. CONCLUSIONS: Although visual loss due to filler injections is rare, it is important that both patient and physician be aware of this risk. In this paper the authors describe methods and techniques available to reduce the risk and also document suggested initial management should a clinician find themselves in this situation.

Efficacy and Safety of PrabotulinumtoxinA for the Treatment of Glabellar Lines in Adult Subjects: Results From 2 Identical Phase III Studies.

BACKGROUND: PrabotulinumtoxinA is a 900-kDa botulinum toxin Type A produced by Clostridium botulinum. OBJECTIVE: To investigate the efficacy and safety of prabotulinumtoxinA for the treatment of glabellar lines. MATERIALS AND METHODS: Adult subjects (n = 330 in EV-001; n = 324 in EV-002) with moderate to severe glabellar lines at maximum frown on the 4-point Glabellar Line Scale (GLS; 0 = no lines, 1 = mild, 2 = moderate, and 3 = severe) were enrolled in 1 of 2 identical 150-day, double-blind, placebo-controlled, single-dose, Phase III studies. Subjects were randomized 3:1 to receive 20-U prabotulinumtoxinA or placebo. The primary efficacy end point was the proportion of responders on Day 30 where the investigator and subject independently agreed that a ≥2-point improvement had occurred on the GLS at maximum frown from Day 0. Adverse events (AEs) were evaluated throughout the study. RESULTS: Responder rates in the prabotulinumtoxinA and placebo groups were 67.5% and 1.2% in EV-001 and 70.4% and 1.3% in EV-002; absolute differences between groups were 66.3% and 69.1% in EV-001 and EV-002, respectively (both p < .001). No serious AE in either study was assessed as study drug related. CONCLUSION: In these studies, a single dose of 20-U prabotulinumtoxinA was safe and effective for the treatment of glabellar lines.

Lip and Perioral Enhancement With Hyaluronic Acid Dermal Fillers in Individuals With Skin of Color.

BACKGROUND: Individuals with skin of color are underrepresented in studies of lip and perioral enhancement. OBJECTIVE: To examine the effectiveness and safety of hyaluronic acid (HA) dermal filler treatment for lip and perioral enhancement in subjects with skin of color. METHODS: Data were pooled from subjects with Fitzpatrick skin phototypes IV, V, or VI in 2 pivotal studies of HA dermal fillers. Photonumeric scales were used to assess lip fullness (5-point scale) and perioral lines and oral commissures severity (each 4-point scales). Safety was assessed by injection site responses recorded in patient diaries and adverse events (AEs). RESULTS: The cohort comprised 72 subjects (median age: 49.5 years; 95.8% female). Mean lip fullness improved from baseline by 1.1 points at 3 months after treatment; 85.0% of subjects were responders (≥1-point improvement). Of subjects treated for perioral lines (n = 12) and oral commissures (n = 56), 90.9% and 46.4%, respectively, were responders. Injection site responses were generally mild or moderate in severity, resolved within 2 weeks, and were consistent with those expected for HA dermal filler treatment. The most common AEs were injection site mass (19.4%) and bruising (12.5%). CONCLUSION: Lip and perioral enhancement with HA dermal fillers is effective and safe in subjects with skin of color.

Polymethylmethacrylate Collagen Gel-Injectable Dermal Filler for Full Face Atrophic Acne Scar Correction.

BACKGROUND/OBJECTIVES: This trial evaluated the effectiveness and safety of Bellafill for full-face acne scar treatment. PATIENTS AND METHODS: In this open-label, nonrandomized, multicenter pilot study investigating the use of polymethylmethacrylate for full-face atrophic acne scar correction, 42 adult subjects with a mean age of 43 years were treated and assessed for safety and effectiveness at Months 4 and 7. There were no hypersensitivity reactions to pretreatment skin testing or during scar treatments. RESULTS: At 4 and 7 months after initial treatment, 92% and 95% of subjects, respectively, were responders with ≥1-point improvement on the 5-point Acne Scar Assessment Scale. Subjects reported very high levels of improvement on the Global Aesthetic Improvement Scale (GAIS), with 95% of subjects reporting "improved or better" at 4 months and 90% at 7 months. The outcome of the physician GAIS was also high with 92% of patients classified as "improved or better" at 4 months and 97% at 7 months. There were only 2 device-related adverse events, both mild events related to Bellafill skin test (bruising, ecchymosis). There were no serious adverse events in response to the treatment product in this short-term follow-up study. CONCLUSION: Polymethylmethacrylate is effective for treating full-face acne scarring.

ATX-101 (Deoxycholic Acid Injection) for Reduction of Submental Fat: Results From a 12-Month Open-Label Study

BACKGROUND: ATX-101 (deoxycholic acid) causes adipocytolysis when injected into subcutaneous fat. OBJECTIVE: Evaluate the long-term safety and efficacy of ATX-101 for submental fat (SMF) reduction. METHODS: Adults (N=165) with moderate-to-extreme SMF received ≤6 treatments of open-label ATX-101 (2 mg/cm2) and were evaluated up to 12 months after last treatment. Efficacy end points included improvements in SMF based on clinician or subject assessment, patient-reported outcomes, downtime (via subject questionnaire), and skin laxity. Safety was evaluated throughout the study. RESULTS: Twelve weeks after last treatment, most subjects achieved a ≥1-grade improvement in SMF based on clinician (86.8%) or subject (83.8%) evaluation; at 12 months, 90.4% and 80.7% of these responders, respectively, maintained the response. Overall, 84.9% of subjects were satisfied with the appearance of their face/chin. At 12 months, 82.9% of subjects had unchanged, and 10.1% had improved, skin laxity relative to 12 weeks after last treatment. Adverse events were mild to moderate and mainly involved the treatment area. During the 7 days after the first treatment, 13.3% of subjects missed work and 33.9% missed social/leisure activities. Following subsequent treatments, 2.4%­6.0% of subjects missed work and 10.0%­15.7% missed social/leisure activities. CONCLUSION: The safety and efficacy of ATX-101 were sustained over 12 months.
