This study is intended to evaluate the efficacy and safety of an initial dose of 120 U, 180 U, and 240 U of abobotulinumtoxinA (with optional touch-up) in the treatment of moderate to severe platysmal bands. The platysmal bands will be treated by intramuscular injection of abobotulinumtoxinA.
This is a double-blinded, dose-ranging study in the US to assess the efficacy, safety, and duration of response of abobotulinumtoxinA for the treatment of moderate to severe platysmal bands.
