Provides Revance entry into the $2.5 billion U.S. therapeutic neuromodulator market.1

Approval expands the DAXXIFY® label to include efficacy data over the 52-week ASPEN repeat dose clinical study.

DAXXIFY® for cervical dystonia is the first and only peptide-formulated, long-lasting neuromodulator, designed to meet the needs of patients seeking improved treatment outcomes.2-5

88% of U.S. cervical dystonia patients experience symptom reemergence eight to 10 weeks after conventional neuromodulator treatment.6

NASHVILLE, TN, USA I August 14, 2023 I Revance Therapeutics, Inc. (Nasdaq: RVNC) today announced that the United States (U.S.) Food and Drug Administration (FDA) has approved the first therapeutic indication for DAXXIFY® (DaxibotulinumtoxinA-lanm) for injection for the treatment of cervical dystonia in adults.7 DAXXIFY®, powered by Peptide Exchange Technology™, was previously approved by the FDA for the temporary improvement of glabellar lines (frown lines) in adults in September 2022 and is the first true innovation in neuromodulator product formulation in more than 30 years.8-11

Cervical dystonia is a chronic, debilitating disease in which the neck muscles contract involuntarily, causing abnormal movements, pain and awkward posture of the head and neck.12,13 Neuromodulators are considered the first line of treatment for this condition, which effects roughly 60,000 Americans. In 2017, the U.S. FDA granted orphan drug designation to DAXXIFY® for the treatment of cervical dystonia in adults.

“We are very pleased to see the expansion of the DAXXIFY® label to include our first therapeutic indication, unlocking a new market opportunity for DAXXIFY® following the product’s recent launch in the aesthetics market. Further, we believe FDA approval represents a significant advancement in the treatment of cervical dystonia,” said Chief Executive Officer Mark J. Foley. “DAXXIFY’s differentiated efficacy, duration and safety profile can help physicians deliver long-lasting symptom relief to patients suffering from cervical dystonia, while also helping payers address the total cost of care for this population. We look forward to conducting our early experience and education program, PrevU, which will involve a small group of thought leaders, followed by a progressive commercial rollout beginning in 2024. Today’s approval is an important milestone for Revance, marking the start to our therapeutics franchise.”

Peter McAllister, M.D., ASPEN investigator and co-founder and medical director of the New England Institute for Neurology and Headache, commented: “As an ASPEN investigator, I am excited to see the approval of a new treatment option to address symptom reemergence prior to retreatment, a common issue for cervical dystonia patients. Currently, patients experience painful and life-limiting symptom recurrence as early as eight to 10 weeks in clinical practice but cannot be re-treated until 12 weeks. DAXXIFY® is the first long-acting neuromodulator that has the potential to address this significant unmet need — demonstrating durable symptom relief between treatment cycles and providing the opportunity to extend treatment intervals.”

The U.S. approval of DAXXIFY® for the treatment of cervical dystonia in adults was based on data generated in the Phase 3 clinical program (ASPEN 1, ASPEN OLS), which included 382 patients and 1,240 treatments across up to five injection cycles over an 88-week time span, based on the masked, randomized ASPEN-1 and ASPEN Open Label Study (OLS).2-5 In the pivotal ASPEN clinical study, DAXXIFY® was shown to be effective, generally safe, and well tolerated across both dose groups, 125U and 250U, with a median duration of effect of 24.0 and 20.3 weeks for the two dose groups respectively.2-3,14-15* Based on the ASPEN OLS study, symptoms continued to improve with successive DAXXIFY® treatments at doses up to 300U, while adverse events remained low.15-16 In particular, dysphagia rates (difficulty swallowing) remained low (2.7% for ASPEN-1 and 4.2% for ASPEN-OLS), further supporting DAXXIFY’s safety profile.15-16

The total U.S. therapeutic neuromodulator market opportunity for DAXXIFY® is $2.5 billion, which includes the $345 million cervical dystonia market.1

About Cervical Dystonia

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. Roughly 60,000 Americans suffer from this muscle movement disorder.
