Brief summary

This study will be conducted in Phase I/II clinical trials. In Phase I, subjects with moderate to severe glabellar lines are enrolled and those who are judged to be eligible for this study will be injected with the PROTOXIN at a total of 20U(4U/0.1mL each) in five sites of the glabellar lines. Safety is assessed after 12 weeks. In Phase II, subjects with moderate to severe glabellar lines are enrolled and will be injected the PROTOXIN or the BOTOX® at a total of 20U(4U/0.1mL each)in five sites of the glabellar lines. Thereafter, efficacy and safety are assessed by comparing with BOTOX®.
