AbbVie Submits Biologics License Application to U.S. FDA for TrenibotulinumtoxinE (TrenibotE) for the Treatment of Glabellar Lines

–TrenibotE is a first-in-class botulinum neurotoxin serotype E characterized by a rapid onset of action as early as 8 hours after administration (earliest assessment time) and shorter duration of effect of 2-3 weeks. 
–If approved, TrenibotE will be the first neurotoxin of its kind available to patients.
–Submission is supported by data from over 2,100 patients treated with TrenibotE throughout the clinical program. 

NORTH CHICAGO, Ill., April 24, 2025 /PRNewswire/ -- AbbVie (NYSE: ABBV) today announced submission of a Biologics License Application (BLA) to the U.S. Food and Drug Administration (FDA) for trenibotulinumtoxinE (TrenibotE) for the treatment of moderate to severe glabellar lines.

"The submission provides evidence of TrenibotE's differentiated clinical profile to offer patients an opportunity to experience a faster onset and shorter treatment duration as an introduction to a neurotoxin," said Darin Messina, Ph.D., senior vice president, aesthetics R&D, AbbVie. "TrenibotE has the potential to transform the aesthetic toxin treatment landscape for new patients interested in the facial aesthetics category."

New patients wanting to experience the aesthetic benefits of a neurotoxin cite "fear of looking unnatural" as a barrier to initiating neurotoxin use for aesthetic indications. If approved, TrenibotE will be the first serotype E neurotoxin offering patients the opportunity to experience a neurotoxin with rapid clinical effect for a shorter duration of time as a trial before getting treatment with BOTOX® Cosmetic.

The BLA submission is supported by data from over 2,100 patients treated with TrenibotE in the clinical program, which included two pivotal Phase 3 clinical studies evaluating TrenibotE for the treatment of moderate to severe glabellar lines (M21-500 and M21-508) and a Phase 3 open-label safety study (M21-509). All primary and secondary endpoints of the Phase 3 studies were met, with a rapid onset of action as early as 8 hours after drug administration (the earliest assessment time) and observed efficacy duration for 2-3 weeks. Treatment-emergent adverse events for TrenibotE were similar to placebo, both as a single treatment and up to three consecutive treatments. Topline data from the Phase 3 pivotal studies were previously shared.

"Concern about an unnatural outcome remains a significant barrier for many patients considering medical aesthetics treatment," said Cheryl Burgess, MD, FAAD, lead clinical investigator for one of the Phase 3 studies. "Treatment with a product offering rapid onset of effect and short duration of action could help address this barrier and empower confidence for patients exploring their aesthetics treatment journey with innovation from the makers of BOTOX® Cosmetic."

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.
