- Primary Outcome Measures
Name Time Method Percentage of Subjects as Responders in the ILA (Using Validated 4-point Photographic Scale) and the SSA of Glabellar Lines at Maximum Frown Day 29 Investigator's live assessment (ILA), subject's self assessment (SSA), Next Generation (NG)
4-point photographic scale: Investigator's live assessment: None - 0; Mild - 1; Moderate - 2; Severe - 3;
4-point photographic scale: Subject's Self assessment: No wrinkles - 0; Mild wrinkles - 1; Moderate wrinkles - 2; Severe wrinkles - 3;
A responder at maximum frown was defined as a subject having a severity grade of none or mild at maximum frown on Day 29 and a severity grade of moderate or severe at maximum frown at Visit 2.
- Secondary Outcome Measures
Name Time Method Percentage of Subjects as Responders at Maximum Frown as Measured by the Subject's Self-assessment. Days 8, 15, 57, 85 and 113 Percentage of Subjects as Responders, as Measured by the Investigator's Live Assessment at Maximum Frown (Comparison With Dysport 50 U) Days 8, 15, 29, 57, 85 and 113 Percentage of Subjects as Responders, as Measured by the Subject's Self Assessment at Maximum Frown (Comparison With Dysport 50 U) Days 8, 15, 29, 57, 85 and 113 Percentage of Subjects as Responders at Maximum Frown as Measured by the Investigator's Live Assessment. Days 8, 15, 57, 85 and 113 Percentage of Subjects as Responders at Rest as Measured by the Investigator's Live Assessment. Days 8, 15, 29, 57, 85 and 113 A responder at rest was defined as a subject having a severity grade of none or mild at rest on the visit day and a severity grade of moderate or severe at rest at Visit 2.
Percentage of Subjects Assessed as Responders, by Both the Investigator's Live Assessment and the Subject's Self-assessment at Maximum Frown. Days 8, 15, 57, 85 and 113 Percentage of Subjects as Responders at Maximum Frown on Day 29 Who Remain Responders Day 113 A responder at maximum frown was defined as a subject having a severity grade of none or mild at maximum frown on the visit day and a severity grade of moderate or severe at maximum frown at Visit 2.
Percentage of Subjects as Assessed as Responders, by Both Investigator's Live Assessment and the Subject's Self-assessment at Maximum Frown. Day 29 A responder at maximum frown was defined as a subject having a severity grade of none or mild at maximum frown on the visit day and a severity grade of moderate or severe at maximum frown at Visit 2.
Percentage of Subjects With a Reduction of Two or More Grades in the Severity of Glabellar Lines at Maximum Frown as Measured by the Investigator's Live Assessment Days 8, 15, 29, 57, 85 and 113 A reduction of two or more grades in the severity of glabellar lines at maximum frown was a change from Visit 2 severity of glabellar lines from severe to mild/none or from Visit 2 severity of moderate to none after treatment as measured by the Investigator's live assessment
Percentage of Subjects With a Reduction of Two or More Grades in the Severity of Glabellar Lines at Rest as Measured by the Investigator's Live Assessment Days 8, 15, 29, 57, 85 and 113 A reduction of two or more grades in the severity of glabellar lines at rest was a change from Visit 2 severity of glabellar lines from severe to mild or from Visit 2 severity of moderate to none after treatment as measured by the Investigator's live assessment.
Percentage of Subjects With a Reduction of Two or More Grades in the Severity of Glabellar Lines at Maximum Frown as Measured by the Subject's Self-assessment Days 8, 15, 29, 57, 85 and 113 A reduction of two or more grades in the severity of glabellar lines at maximum frown was a change from Visit 2 severity of glabellar lines from severe to mild/no wrinkles or from Visit 2 severity of moderate to no wrinkles after treatment as measured by the subjects self assessment.
