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

Study Overview
=================
Brief Summary
-----------------
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.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Responders on the Severity of Lateral Canthal Lines at Maximum Smile. | A positive response (responder) is defined as a grade of 0 or 1 (none or mild), as assessed by the investigator. | Week 4 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Participants Satisfied With the Appearance of Their Lateral Canthal Lines | Participants were asked to assess their degree of satisfaction with the appearance of their lateral canthal lines using a 4-point scale with the grades Very satisfied, Satisfied, Dissatisfied, and Very dissatisfied. A participant is considered satisfied if he/she answers Very satisfied or Satisfied. | Week 4 |
