The trial's primary endpoint, the reduction in the patient-reported visual analog scale (VAS) for pain at Week 8, showed a robust impact on pain, with a greater than 50% reduction for patients treated with RT002. In the intent-to-treat population, a mean reduction in the VAS score of 54.2% from baseline was achieved with RT002, compared with a 42.6% reduction in the placebo group, which upon further subgroup analysis, was driven primarily by a strong placebo response in the control group at two of the five study sites. While not statistically significant (p=0.39), RT002 did outperform placebo, providing patients with considerable pain relief. Similar numeric trends were seen in the secondary and exploratory endpoints.
RT002 appeared to be generally safe and well-tolerated through Week 8. The majority of adverse events in both treatment groups were mild in severity. There were no treatment-related serious adverse events. The most common treatment-related adverse events for RT002 and placebo were injection site pain (10.0 percent and 10.3 percent) and muscle weakness (3.3 percent and 3.4 percent), both respectively, all of which were classified as mild in severity.

About Plantar Fasciitis
Heel pain is the most common complaint of patients who visit podiatrists and orthopaedic foot and ankle surgeons. Eighty percent of reported heel pain complaints are due to plantar fasciitis, which is caused by tears in the fascia that in turn lead to inflammation of the connective tissue in the arch of the foot.1 The fascia is a sheet or band of fibrous connective tissue under the skin that covers a surface of underlying tissues. Fascia surrounds each of the muscles that move the skeleton. When the fascia is inflamed, the condition is referred to as "fasciitis."2
Plantar fasciitis is estimated to affect 10 to 18 million individuals in
Treatment options for less severe cases include leg and foot stretching exercises, nonsteroidal anti-inflammatory drugs, shoe inserts, heel pads, and night splints. More severe or refractory cases are currently treated with steroid injections, extracorporeal shock wave therapy, platelet rich plasma injections, and/or surgery.5
DaxibotulinumtoxinA for Injection (RT002) is an investigational product. It is a novel, next-generation neuromodulator in development for the treatment of aesthetic and therapeutic conditions, including glabellar lines, cervical dystonia and plantar fasciitis. Created using Revance's proprietary peptide technology, RT002 has the potential to become the first neuromodulator with long-acting duration of six months for the treatment of glabellar lines. This proprietary, stabilizing excipient peptide technology eliminates the need for human- and animal-based components, which carry a potential risk of transmitting pathogens.
Revance has two other active clinical programs for RT002 injectable under way. In December of 2017, Revance announced positive SAKURA 1 and SAKURA 2 Phase 3 pivotal trials to treat glabellar lines. With the SAKURA 3 open-label, long-term safety study fully enrolled, the company plans to complete the safety study in the second half of 2018 and file its biologics license application (BLA) with the
