Primary
| Measure | Time frame | Description |
|---|---|---|
| Percentage of Responders Based on Composite Facial Wrinkle Scale Assessment of Crow's Feet Line Severity at Maximum Smile | Baseline, Day 30 | The composite facial wrinkle scale assessment is based on both the Investigator and Subject Facial Wrinkle scales at Day 30. The Investigator assessed the severity of the patient's Crow's Feet Lines at maximum smile using the 4-point Facial Wrinkle Scale: 0=none, 1=mild, 2=moderate or 3=severe and the patient assessed the severity of their Crow's Feet Lines at maximum smile using the same 4-point Facial Wrinkle Scale. A responder is defined as a participant with a ≥ 2-grade improvement from Baseline. |
