The trial enrolled 37 subjects and follows three sequential treatment cohorts for up to a total of 24 weeks after treatment for each cohort. The trial's first cohort of 12 subjects received a single dose of up to 200 units of RT002 injectable, the second cohort of 12 subjects received between 200 and 300 units, and the third cohort received from 300 to 450 units. Later-enrolled subjects in the second and third cohorts have yet to complete the trial's 24-week protocol. Today's results are therefore preliminary, with final results expected in the first half of 2017.
Interim Results from the Phase 2 Cervical Dystonia trial:
"Patients with cervical dystonia suffer from painful, embarrassing
twisting movements of the neck, often impairing their ability to work,
drive and perform activities of daily living," said lead trial
"Cervical dystonia is an ideal therapeutic indication for testing the
attributes of RT002 injectable," said
"Further, RT002 injectable, even at high doses, may deliver a strong safety profile possibly by limiting the spread of toxin, which could avoid life-altering adverse events such as general muscle weakness and difficulty swallowing," Browne continued. "We plan to share the final safety, efficacy, and duration results in 2017 once all cohorts have completed the 24-week assessment period. We then intend to seek regulatory advice from US and EU health authorities to determine the next steps in this clinical program."
The abstract for this Phase 2 clinical trial of RT002 injectable to

Phase 2 Study Design
Revance's Phase 2 trial is an open-label, sequential, dose-escalating
study to evaluate the safety, preliminary efficacy and duration of
effect of a single treatment of DaxibotulinumtoxinA Injectable (RT002)
for isolated cervical dystonia. Thirty-seven subjects with at least
moderate cervical dystonia were enrolled at multiple sites in
The primary efficacy endpoint of the Phase 2 study is an improvement in dystonia symptoms as measured by change (reduction) from baseline in Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS) total score at four weeks. TWSTRS is a composite scale that covers different features of the cervical dystonia condition. The first part of the scale is based on the physical findings and severity of dystonia, the second part rates the patient's perceived level of disability, and the third part rates the pain. The study protocols also feature a number of secondary efficacy endpoints, including duration of effect and patient-rated quality of life as measured by change from baseline in Cervical Dystonia Impact Profile (CDIP).
All subjects are followed out to nine weeks, after treatment. Subjects with sustained improvement after this initial period of nine weeks continue to be assessed for duration of efficacy and other measures until they return to baseline or for up to a total of 24 weeks after treatment.

About Cervical Dystonia
According to the
Treatments for cervical dystonia include oral medications, botulinum
toxin injections, surgery, and complementary therapies. Botulinum toxin
can help block the communication between the nerve and the muscle and
may alleviate abnormal movements and postures. Current botulinum toxin
treatments for cervical dystonia have a duration of effect of
approximately three months. Cervical dystonia can occur at any age,
although most individuals first experience symptoms in middle age. It
affects several hundred thousand adults and children in
Revance, a Silicon Valley-based biotechnology company, is committed to the advancement of remarkable science. The company is developing a portfolio of products for aesthetic medicine and underserved therapeutic specialties, including dermatology, orthopedics and neurology. Revance's science is based upon a proprietary TransMTS® peptide technology, which when combined with active drug molecules, may help address current unmet needs.
Revance's initial focus is on developing daxibotulinumtoxinA, the company's highly purified botulinum toxin, for a broad spectrum of aesthetic and therapeutic indications, including facial wrinkles and muscle movement disorders. The company's lead drug candidate, DaxibotulinumtoxinA for Injection (RT002), is currently in development for the treatment of glabellar lines, cervical dystonia and plantar fasciitis with the potential to be the first long-acting neurotoxin. The company holds worldwide rights for all indications of RT002 injectable and RT001 topical and the pharmaceutical uses of the TransMTS technology platform.
