Both SAKURA 1 and SAKURA 2 met the primary composite endpoint by delivering highly statistically significant improvement against placebo in reducing the severity of glabellar lines, i.e., the frown lines or wrinkles between the brows. The percent of RT002-treated patients who had none or mild wrinkles and achieved at least a two-point improvement from baseline on both validated physician and patient assessments were 73.6 percent in SAKURA 1 and 74.0 percent in SAKURA 2 compared to placebo (p < 0.0001) at Week 4. Also at that time point, 88 percent of RT002-treated patients in SAKURA 1 and 91 percent of RT002 patients in SAKURA 2 said they were very satisfied or satisfied with their treatment experience.
All secondary endpoints measuring reduction in severity of glabellar lines with RT002 compared to placebo were highly statistically significant at every time point evaluated to 24 weeks. On an additional key secondary endpoint, median duration for patients treated with RT002 to return to baseline wrinkle severity was nearly 27 weeks (SAKURA 1: 27.7 weeks and SAKURA 2: 26.0 weeks) as assessed by both physicians and patients.

TOP-LINE 36-WEEK RESULTS
PRIMARY ENDPOINT
The primary efficacy measurement was a composite of the proportion of patients who achieved a score of 0 or 1 (none or mild) and at least a two-point improvement from baseline at maximum contraction (frown) in glabellar line severity on both the Investigator Global Assessment-Facial Wrinkle Severity (IGA-FWS) and Patient Facial Wrinkle Severity (PFWS) scales at Week 4.

Percent of patients who achieved the primary composite endpoint:
- SAKURA 1: 73.6 percent of patients vs. 0 percent for placebo (p < 0.0001)
- SAKURA 2: 74.0 percent vs. 1.0 percent for placebo (p < 0.0001)
SECONDARY DURATION ENDPOINTS
There were several secondary endpoints used to evaluate duration of effect, including the proportion of patients achieving none or mild response on IGA-FWS compared to placebo, median duration for time to loss of none or mild wrinkle severity on both IGA-FWS and PFWS, and median duration for time to return to baseline on both IGA-FWS and PFWS.
-
The percent of patients treated with RT002 who achieved a none or mild
response on IGA-FWS at Week 24:
- SAKURA 1: 35.3 percent vs. 2.0 percent for placebo (p < 0.0001)
- SAKURA 2: 29.4 percent vs. 2.0 percent for placebo (p < 0.0001)
-
Median duration for time to loss of none or mild wrinkle severity on
both IGA-FWS and PFWS for patients treated with RT002:
- SAKURA 1: 24.0 weeks
- SAKURA 2: 23.9 weeks
-
Median duration for time to return to baseline wrinkle severity on
both IGA-FWS and PFWS for patients treated with RT002:
- SAKURA 1: 27.7 weeks
- SAKURA 2: 26.0 weeks
For comparison, an additional exploratory duration endpoint was
evaluated, which mirrors the duration measure used in the

SAFETY
RT002 appeared to be generally safe and well-tolerated through the end of study at Week 36. Adverse events were mild, localized and transient. There were no treatment-related serious adverse events. The most common adverse events for RT002 in both studies combined were headache (6.4 percent) and injection site pain (3.7 percent). The incidence of eyelid ptosis and brow ptosis were 2.2 percent and 0.7 percent, respectively.
About SAKURA Phase 3 Clinical Program
The SAKURA clinical program includes SAKURA 1 and SAKURA 2 - two
randomized, double-blind, placebo-controlled pivotal trials that were
identical in design to evaluate the safety and efficacy of a single
administration of RT002 for the treatment of moderate-to-severe
glabellar lines in adults from 18 to 75 years of age. The SAKURA 1 and
SAKURA 2 trials enrolled a total of 609 patients at 30 sites in the
The primary efficacy endpoint was the composite of the proportion of patients who achieved a score of 0 or 1 (none or mild) and at least two-point improvement from baseline in glabellar line severity on both the Investigator Global Assessment-Facial Wrinkle Severity (IGA-FWS) and Patient Facial Wrinkle Severity (PFWS) scales, at maximum contraction (frown), at Week 4. Duration of the reduction of severity of glabellar lines was assessed as secondary efficacy endpoints.
The program also includes an open-label trial designed to evaluate the
long-term safety of RT002 in glabellar lines following both single and
repeat treatment administration. The long-term safety trial enrolled
more than 2,500 patients at 66 sites in the
About Glabellar Lines
The glabella is the skin between the eyebrows and above the nose. Glabellar lines, often called "frown lines," are vertical lines that develop between the eyebrows and may appear as a single vertical line or as two or more lines and may also appear angled toward the inner corners of the eyebrows. When you frown, the muscles of the lower forehead contract in a downward direction, causing the skin between the eyebrows to crease. Lines are formed by the repeated action of frowning due to the lack of elasticity in the skin. Age, sun exposure, and genetics are contributing factors. Botulinum toxin is used to block the nerve impulses, temporarily inhibiting movement of the muscles that cause the frown lines, giving the skin a smoother, more refreshed appearance.

About RT002
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. 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 three active clinical programs for RT002 injectable under way. With the SAKURA 1 and SAKURA 2 Phase 3 pivotal trials to treat glabellar lines now completed, Revance plans to complete the SAKURA 3 open-label, long-term safety study in the second half of 2018. For cervical dystonia, the company was recently granted orphan drug designation and plans to initiate a Phase 3 program in 2018. A Phase 2 trial for RT002 for the management of plantar fasciitis is fully enrolled, and the company plans to share results by year end 2017.
