Brief Summary

This is a phase 1/2, multicenter, randomized, double-blind, active-controlled and placebo-controlled study to evaluate safety,immunogenicity and efficacy of YY001 for the treatment of moderate to severe glabellar lines in male and female subjects of Chinese origin. The study has been designed to test the safety,efficacy,immunogenicity of YY001,and compare to onabotulinumtoxinA (BOTOX®) and placebo, in improving the appearance of moderate to severe glabellar lines.
