Investigational Neurotoxin TrenibotulinumtoxinE Demonstrates Rapid Results as Early as 8 Hours and Short Duration with Consistent Efficacy and Safety 

Research shows that investigational neurotoxin trenibotulinumtoxinE (TrenibotE) delivers rapid results as early as 8 hours, a short duration of 2-3 weeks, and consistent efficacy with safety observed across diverse patient populations.

Key Findings:

• Rapid and consistent improvement in moderate-to-severe glabellar lines, with results observed as early as 8 hours and comparable efficacy and safety across East Asian and North American/European populations
• Effective and well-tolerated in both toxin-naïve patients and those previously treated with onabotulinumtoxinA (BOTOX^® Cosmetic), supporting use across treatment histories
• High patient satisfaction with natural-looking results, along with improvements in psychosocial outcomes following treatment
• Early evidence supports sequential treatment with TrenibotE followed by onabotulinumtoxinA (BOTOX^® Cosmetic) as a well-tolerated and effective approach for glabellar lines

BOTOX^® Cosmetic: Patient Satisfaction, Natural-Looking Results and Integrated Aesthetic Care

Recent studies on onabotulinumtoxinA (BOTOX^® Cosmetic) solidify its position as the leading neuromodulator in facial aesthetics globally, delivering high patient satisfaction, natural-looking results and improved psychological well-being. New real-world data show long-term use is frequently followed by adoption of additional aesthetic treatments.

Key Findings:

• High patient satisfaction and natural-looking results for upper facial lines, with improvements in psychological well-being among toxin-naïve patients
• Long-term use of onabotulinumtoxinA (BOTOX^® Cosmetic) may serve as an entry point to broader aesthetic treatment approaches for patients
• Patient preference research in China identifies key factors influencing treatment decisions for masseter reduction, including procedure standardization, degree of slimming, duration, side effects and cost
• Real-world evidence suggests patients receiving long-term onabotulinumtoxinA (BOTOX^® Cosmetic) treatment often progress to multimodal care, including additional facial aesthetic procedures over time

Injectable Hyaluronic Acid Treatments (VYC-12L and VYC-20L): Clinical Evidence Across Neck, Perioral and Skin Quality Indications

Data demonstrate that VYC-12L (SKINVIVE by JUVÉDERM^®), a hyaluronic acid intradermal microdroplet injection, and VYC-20L (JUVÉDERM^® VOLUMA^® XC) are effective and well-tolerated across multiple indications, with up to 6 months of sustained improvement in neck lines, perioral lines and skin quality, alongside evidence of stability, biocompatibility and injector usability.

Key Findings:

• VYC-12L reduces neck and perioral lines, with results sustained for up to 6 months and safety observed across study populations
• VYC-12L improves skin quality, including cheek smoothness, supporting use across facial indications
• In Chinese adults, VYC-12L demonstrates significant improvement in perioral lines with high responder rates and durability up to 6 months
• VYC-20L preclinical and usability data support stability, biocompatibility and improved injector experience
• New elongated plunger cap syringe shows improvements in injector comfort, ease of use and reduced hand fatigue compared to standard designs

HA-CaHA Injectables (HArmonyCa) Demonstrate Durable Skin Quality Improvements, Including in Patients Undergoing Medical Weight Loss

Clinical studies demonstrate that HA-CaHA injectables are effective and well-tolerated, delivering measurable improvements in skin quality and midface volume with results lasting up to 18 months. Subgroup analyses also suggest potential benefits in patients undergoing medical weight loss, including those treated with GLP-1 therapies.

Key Findings:

• HA-CaHA injectables were shown to improve skin quality, including elasticity, firmness, tightening and cheek smoothness, extending beyond volumization alone
• Results are durable, with improvements in midface volume and skin quality sustained for up to 18 months
• Subgroup analyses suggest HA-CaHA may improve midface volume and patient satisfaction in individuals undergoing medical weight loss, with effect observed up to 18 months

Body Contouring (CoolSculpting^®) Demonstrates Continued Clinical Utility, Including in Medical Weight Loss Patients

Body contouring aesthetic procedures, such as CoolSculpting^®, continue to have clinical utility in the treatment of patients with stubborn fat and may also play a role in those patients undergoing medical weight loss.

Key Findings:

• Highly desired among women, with the abdomen and flanks reported as the most bothersome areas for stubborn fat
• High patient satisfaction with helping patients achieve fat reduction in areas resistant to diet and exercise
• Induces beiging and metabolic activation in white adipose tissue, offering molecular evidence for lasting fat reduction efficacy

Collectively, these findings highlight the effectiveness and safety of integrated, layered treatment approaches across the Allergan Aesthetics portfolio. Attendees at AMWC can expect comprehensive scientific evidence underscoring Allergan Aesthetics' leadership in neurotoxin and multimodal aesthetic treatment strategies designed to help practitioners meet evolving patient goals.

BOTOX^® Cosmetic (onabotulinumtoxinA) Important Information

Indications

BOTOX^® Cosmetic (onabotulinumtoxinA) is indicated in adult patients for the temporary improvement in the appearance of:

- Moderate to severe glabellar lines associated with corrugator and/or procerus muscle activity

- Moderate to severe lateral canthal lines associated with orbicularis oculi activity

- Moderate to severe forehead lines associated with frontalis activity

- Moderate to severe platysma bands associated with platysma muscle activity

IMPORTANT SAFETY INFORMATION, INCLUDING BOXED WARNING 

CONTRAINDICATIONS

BOTOX^® Cosmetic is contraindicated in the presence of infection at the proposed injection site(s) and in individuals with known hypersensitivity to any botulinum toxin preparation or to any of the components in the formulation.

WARNINGS AND PRECAUTIONS

Lack of Equivalency Between Botulinum Toxin Products

The potency Units of BOTOX^® Cosmetic are specific to the preparation and assay method utilized. BOTOX^® Cosmetic is not equivalent to other preparations of botulinum toxin products, and therefore, Units of biological activity of BOTOX^® Cosmetic cannot be compared to nor converted into Units of any other botulinum toxin products assessed with any other specific assay method.

Spread of Toxin Effect

Please refer to Boxed Warning for Distant Spread of Toxin Effect.

No definitive serious adverse event reports of distant spread of toxin effect associated with dermatologic use of BOTOX^® Cosmetic at the labeled dose of 20 Units (for glabellar lines), 24 Units (for lateral canthal lines), 40 Units (for forehead lines with glabellar lines), 44 Units (for simultaneous treatment of lateral canthal lines and glabellar lines), and 64 Units (for simultaneous treatment of lateral canthal lines, glabellar lines, and forehead lines) have been reported. Patients or caregivers should be advised to seek immediate medical care if swallowing, speech, or respiratory disorders occur.

Serious Adverse Reactions With Unapproved Use

Serious adverse reactions, including excessive weakness, dysphagia, and aspiration pneumonia, with some adverse reactions associated with fatal outcomes, have been reported in patients who received BOTOX^® injections for unapproved uses. In these cases, the adverse reactions were not necessarily related to distant spread of toxin, but may have resulted from the administration of BOTOX^® to the site of injection and/or adjacent structures. In several of the cases, patients had preexisting dysphagia or other significant disabilities. There is insufficient information to identify factors associated with an increased risk for adverse reactions associated with the unapproved uses of BOTOX^®. The safety and effectiveness of BOTOX^® for unapproved uses have not been established.

Hypersensitivity Reactions

Serious and/or immediate hypersensitivity reactions have been reported. These reactions include anaphylaxis, serum sickness, urticaria, soft-tissue edema, and dyspnea. If such a reaction occurs, discontinue further injection of BOTOX Cosmetic and immediately institute appropriate medical therapy. One fatal case of anaphylaxis has been reported in which lidocaine was used as the diluent and, consequently, the causal agent cannot be reliably determined.

Cardiovascular System

There have been reports following administration of BOTOX^® of adverse events involving the cardiovascular system, including arrhythmia and myocardial infarction, some with fatal outcomes. Some of these patients had risk factors, including preexisting cardiovascular disease. Use caution when administering to patients with preexisting cardiovascular disease.

Increased Risk of Clinically Significant Effects With Preexisting Neuromuscular Disorders

Patients with neuromuscular disorders may be at increased risk of clinically significant effects, including generalized muscle weakness, diplopia, ptosis, dysphonia, dysarthria, severe dysphagia, and respiratory compromise from onabotulinumtoxinA (see Warnings and Precautions). Monitor individuals with peripheral motor neuropathic diseases, amyotrophic lateral sclerosis or neuromuscular junction disorders (eg, myasthenia gravis or Lambert-Eaton syndrome) when given botulinum toxin.

Dysphagia and Breathing Difficulties

Treatment with BOTOX^® and other botulinum toxin products can result in swallowing or breathing difficulties. Patients with preexisting swallowing or breathing difficulties may be more susceptible to these complications. In most cases, this is a consequence of weakening of muscles in the area of injection that are involved in breathing or oropharyngeal muscles that control swallowing or breathing (see Boxed Warning).

Preexisting Conditions at the Injection Site

Use caution when BOTOX^® Cosmetic treatment is used in the presence of inflammation at the proposed injection site(s) or when excessive weakness or atrophy is present in the target muscle(s).

Dry Eye in Patients Treated With BOTOX^® Cosmetic

There have been reports of dry eye associated with BOTOX^® Cosmetic injection in or near the orbicularis oculi muscle. If symptoms of dry eye (eg, eye irritation, photophobia, or visual changes) persist, consider referring patients to an ophthalmologist.

Human Albumin and Transmission of Viral Diseases

This product contains albumin, a derivative of human blood. Based on effective donor screening and product manufacturing processes, it carries a remote risk for transmission of viral diseases and variant Creutzfeldt-Jakob disease (vCJD). There is a theoretical risk for transmission of Creutzfeldt-Jakob disease (CJD), which would also be considered remote. No cases of transmission of viral diseases, CJD, or vCJD have ever been identified for licensed albumin or albumin contained in other licensed products.

ADVERSE REACTIONS

The most frequently reported adverse reactions following injection of BOTOX^® Cosmetic for glabellar lines were eyelid ptosis (3%), facial pain (1%), facial paresis (1%), and muscular weakness (1%).

The most frequently reported adverse reaction following injection of BOTOX^® Cosmetic for lateral canthal lines was eyelid edema (1%).

The most frequently reported adverse reactions following injection of BOTOX^® Cosmetic for forehead lines with glabellar lines were headache (9%), brow ptosis (2%), and eyelid ptosis (2%).

The safety profile of BOTOX^® Cosmetic treatment of platysma bands is consistent with the known safety profile of BOTOX^® Cosmetic for other indications.

DRUG INTERACTIONS

Coadministration of BOTOX^® Cosmetic and aminoglycosides or other agents interfering with neuromuscular transmission (eg, curare-like compounds) should only be performed with caution as the effect of the toxin may be potentiated. Use of anticholinergic drugs after administration of BOTOX^® Cosmetic may potentiate systemic anticholinergic effects.

The effect of administering different botulinum neurotoxin products at the same time or within several months of each other is unknown. Excessive neuromuscular weakness may be exacerbated by administration of another botulinum toxin prior to the resolution of the effects of a previously administered botulinum toxin.

Excessive weakness may also be exaggerated by administration of a muscle relaxant before or after administration of BOTOX^® Cosmetic.

USE IN SPECIFIC POPULATIONS

There are no studies or adequate data from postmarketing surveillance on the developmental risk associated with use of BOTOX^® Cosmetic in pregnant women. There are no data on the presence of BOTOX^® Cosmetic in human or animal milk, the effects on the breastfed child, or the effects on milk production.

Please see BOTOX^® Cosmetic full Prescribing Information, including Boxed Warning and Medication Guide.
