– Two presentations highlighting data on DAXXIFY® for the treatment of cervical dystonia, including a new analysis from ASPEN trials assessing patient-desired retreatment intervals and one abstract examining the influence of DAXXIFY’s formulation on clinical performance

Revance Therapeutics, Inc. (NASDAQ: RVNC), today announced two poster presentations on DAXXIFY® for the treatment of cervical dystonia at the annual meeting of American Academy of Neurology (AAN), taking place April 13-18, 2024, in Denver, Colorado.

In the ASPEN-1 and ASPEN-OLS (open label study), a new analysis found that among patients that requested early retreatment with DAXXIFY®, roughly 50% of peak efficacy remained at the time of their request. In the ASPEN-OLS 52-week long-term follow-up study, approximately 60% of retreatments were at 16 weeks or later. These findings suggest that the long-acting symptom control with DAXXIFY® allows physicians the flexibility to customize treatment intervals for each patient, without being limited by the FDA and payer-defined minimum treatment interval of 12 weeks (as is the case with conventional neurotoxins). Additionally, the studies show that adverse event rates remained low across all retreatment scenarios.

“While it may not be surprising that many patients prefer to be retreated as their symptoms first re-emerge rather than waiting to return to baseline, we believe that the duration of DAXXIFY offers the potential for physicians to tailor doses and retreatment intervals to the needs of individual patients, in order to provide sustained symptom control and reduce the symptom rollercoaster experienced by a vast number of those suffering with cervical dystonia,” said David. A. Hollander, MD, MBA, Chief Medical Officer and Global Therapeutics Franchise Lead.

A second poster, by Dr. Han Lee and colleagues, examines DAXXIFY’s novel formulation and the role of Revance’s custom-engineered peptide (RTP004), in clinical performance. The data shows that the benefits of RTP004 include increased binding of neurotoxin to cell membranes to allow more toxin to enter the neuron, enhanced SNAP-25 cleavage in neurons in a dose-dependent manner, and localization in the injected muscle. By increasing bioavailability, DAXXIFY’s formulation allows for a lower amount of core neurotoxin to be administered while maintaining long lasting benefit, which may contribute to the strong safety and differentiated performance profile.

DAXXIFY® (daxibotulinumtoxinA-lanm) injection IMPORTANT SAFETY INFORMATION INDICATIONS

DAXXIFY® (daxibotulinumtoxinA-lanm) injection is an acetylcholine release inhibitor and neuromuscular blocking agent indicated for the temporary improvement in the appearance of moderate to severe glabellar lines associated with corrugator and/or procerus muscle activity in adult patients and for the treatment of cervical dystonia in adults.

WARNING: DISTANT SPREAD OF TOXIN EFFECT

The effects of DAXXIFY® and all botulinum toxin products may spread from the area of injection to produce symptoms consistent with botulinum toxin effects. These symptoms have been reported hours to weeks after injection. Swallowing and breathing difficulties can be life threatening and there have been reports of death. DAXXIFY® is not approved for the treatment of spasticity or any conditions other than cervical dystonia and glabellar lines.

IMPORTANT SAFETY INFORMATION

Contraindications

DAXXIFY® contraindications include hypersensitivity to any botulinum toxin preparation or any of the components in the formulation and infection at the injection site(s).

Warnings and Precautions

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

The potency units of DAXXIFY® are not interchangeable with preparations of other botulinum toxin products. Recommended dose and frequency of administration should not be exceeded. Patients should seek immediate medical attention if respiratory, speech or swallowing difficulties occur. Use caution when administering to patients with pre-existing cardiovascular disease. Concomitant neuromuscular disorders may exacerbate clinical effects of treatment.

Adverse Reactions

The most commonly observed adverse reactions are:

Glabellar lines (≥1%): headache (6%), eyelid ptosis (2%) and facial paresis (1%).

Cervical dystonia (≥5%): headache (9%), injection site pain (8%), injection site erythema (5%), muscular weakness (5%), and upper respiratory tract infection (5%).

Drug Interactions

Co-administration of DAXXIFY® and aminoglycoside antibiotics, anticholinergic agents or any other agents interfering with neuromuscular transmission or muscle relaxants should only be performed with caution as the effect of DAXXIFY® may be potentiated. The effect of administering different botulinum neurotoxins during course of treatment with DAXXIFY® is unknown.

Use in Specific Populations

DAXXIFY® is not recommended for use in children or pregnant women.

Please see DAXXIFY® full Prescribing Information, including Boxed Warning and Medication Guide.

About Cervical Dystonia

According to the Dystonia Medical Research Foundation, cervical dystonia is a painful condition in which the neck muscles contract involuntarily, causing abnormal movements and awkward posture of the head and neck. The movements may be sustained (tonic), jerky (clonic), or a combination. Cervical dystonia (also referred to as spasmodic torticollis) may be primary (meaning that it is the only apparent neurological disorder, with or without a family history) or may be the result of secondary causes (such as physical trauma).

First-line treatment for cervical dystonia is usually neuromodulator (botulinum toxin) injections, but additional treatments can include oral medications, surgery, and complementary therapies. Neuromodulators block the communication between the nerve and the muscle, relaxing the muscle, which alleviates abnormal involuntary movements and postures. Cervical dystonia can occur at any age, although most individuals first experience symptoms in middle age. The condition affects roughly 60,000 people in the United States.
