TOP-LINE 24-WEEK RESULTS
• DURATION OF EFFECT AT LEAST 24 WEEKS: The median duration of effect was at least 24 weeks for each of the three dose cohorts studied. Duration of effect was defined as the number of weeks from treatment until the return of signs and symptoms that warrant retreatment, based on subjects reaching their target Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS) score. For reference, current treatment of cervical dystonia calls for injection of botulinum toxin approximately every 3 months (12 weeks), or 4 times per year.
• POSITIVE EFFICACY RESULTS: The trial's 4-week primary efficacy measurement was the improvement in signs and symptoms of cervical dystonia as determined by reduction of the TWSTRS-Total score from baseline. At Week 4, RT002 injectable showed a clinically significant mean reduction of 38% from baseline across all three cohorts. This reduction continued to increase to 50% at Week 6 for all subjects, was 42% at Week 12 and was maintained at or above 30% through Week 24. For reference, placebo-controlled trials for botulinum toxin type A products approved to treat cervical dystonia had a reduction in the TWSTRS-Total score from baseline of 21% to 26% at Week 4 and 13% to 16% at Week 12.
On the key secondary endpoint, percentage of responders showing improvement on Clinician Global Impression of Change (CGIC), 97% of all subjects experienced an improvement in cervical dystonia symptoms at Week 4.
• GENERALLY SAFE AND WELL-TOLERATED: In all three cohorts, RT002 injectable appeared to be generally safe and well-tolerated through Week 24. There were no serious adverse events and no dose-dependent increase in adverse events. The treatment-related adverse events were generally transient and mild to moderate in severity, with one case of neck pain reported as severe. The most common adverse events were dysphagia, or difficulty in swallowing (14%), of which all cases were mild in severity, injection site redness (8%), injection site bruising (5%), injection site pain (5%), muscle tightness (5%) and muscle weakness (5%). For reference, trials for botulinum toxin type A products approved to treat cervical dystonia have adverse events for dysphagia ranging from 13% to 39%.
Based on these Phase 2 results, the company expects to discuss next steps in this clinical program with the US and EU regulatory agencies later this year.
"Patients with cervical dystonia suffer from considerable pain and
debilitation, which dramatically impacts their quality of life. Nearly
all subjects in this study responded to treatment and a majority were
still responding to RT002 at 24 weeks. These results represent the
potential for a meaningful advancement in the treatment of cervical

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
moderate-to-severe cervical dystonia were enrolled at multiple sites in
The primary efficacy endpoint of the Phase 2 study was 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 validated 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 pain associated with the condition. The study protocol also feature a number of secondary efficacy endpoints.
All subjects were followed until they returned to baseline or for up to a total of 24 weeks after treatment. Due to the long duration of effect seen in the first cohort, subjects in the second and third cohorts were given the option to continue. Several patients elected to remain in the study and will be followed for up to 36 weeks.
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 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 neuromodulator. The company holds worldwide rights for all indications of RT002 injectable and RT001 topical and the pharmaceutical uses of its proprietary peptide technology platform.
