Plain-language summary
The aim of this study is to evaluate the efficacy and safety of AbobotulinumtoxinA (produced by Espad Pharmed Darou Co.) for correction of moderate to severe glabellar lines.
Hypothesis: AbobotulinumtoxinA (produced by Espad Pharmed Darou Co.) has acceptable efficacy and safety profile for correction of moderate to severe glabellar lines.
Primary Outcome: To verify the non-inferiority of the efficacy of AbobotulinumtoxinA (produced by Espad Pharmed Darou Co.) compared with AbobotulinumtoxinA (Dysport®, produced by Ipsen Co.) by percentage of responders at maximum frown at day 30 after treatment.
Researchers will compare the efficacy and safety profile of AbobotulinumtoxinA (produced by Espad Pharmed Darou Co.) with AbobotulinumtoxinA (Dysport®, produced by Ipsen Co.).
The study is designed as phase III, randomized, two armed, double-blind, parallel, active controlled, non-inferiority clinical trial.
Participants received a total dose of 40-60 units into 3 to 5 sites. After two weeks, a touch-up intervention could be done based on physician's assessment.
