A Multi-Center Study Of CD07743 for the Improvement of Lateral Canthal Lines (CROW'S FEET)

A Multi-center Randomized, Double-blind, Placebo Controlled, Parallel-group Study of CD07743 for the Improvement of Lateral Canthal Lines (Crow's Feet)

This double-blind study has two parts for each subject (same population):

Part A: initial treatment in Lateral Canthal Lines (LCL) (placebo-controlled):

• To assess the efficacy and safety of Azzalure® compared to placebo in the improvement of moderate to severe LCLs.
• To assess the subjects' level of satisfaction with the appearance of their LCLs compared to placebo.

Part B: repeated treatment in LCL with or without Glabellar Lines (GL) (active treatment, up to 1 year):

• To assess safety of Azzalure® following repeated administration in the improvement of moderate to severe LCLs.
• To assess the safety of Azzalure® when used concomitantly for improvement of moderate to severe LCLs and GLs.
• To assess the subjects' level of satisfaction with the appearance of their LCLs.
