Brief summary
This study design is a parallel, active drug controlled, double blind, randomized, multi-centered, phase III clinical trial to compare the efficacy and safety of MT10107 versus BOTOX® in treatment of glabella line.
Detailed description
This study design is a parallel, active drug controlled, double blind, randomized, multi-centered, phase III clinical trial to compare the efficacy and safety of MT10107 versus BOTOX® in treatment of glabella line. Subjects who voluntarily signed the informed consent and are judged to be eligible for this study will be intramuscularly injected with the study drug or the comparator at a total of 20U (4U/0.1ml each) in five sites of the glabella line. Thereafter, follow-up visits will be made at 4 weeks, 10 weeks, 16 weeks and the efficacy and safety assessments will be conducted for a total of 16 weeks.
Interventions
DRUGBotox (Botulinum toxin type A)
20U of the investigational drug will be intramuscularly injected to 5 sites of the glabella line. Treatment will be conducted just once in visit 2.
DRUGMT10107 (Botulinum toxin type A)
20U of the investigational drug will be intramuscularly injected to 5 sites of the glabella line. Treatment will be conducted just once in visit 2.
