What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Superiority Analysis of The Percentage of Responders Measured by the Investigator's Live Assessment (ILA) at Maximum Frown at Cycle 1, Day 29 (DB Period).

    At baseline (Cycle 1, Day 1) and at Cycle 1, Day 29, the Investigator assessed the appearance of the glabellar lines at maximum frown using a validated 4-point Photographic Scale of Glabellar Line Severity. This 4-point scale rated the severity of glabellar lines as Grade 0 (none), Grade 1 (mild), Grade 2 (moderate) and Grade 3 (severe). A responder was defined as having a severity grade of 0 or 1 at Cycle 1, Day 29, and a severity grade of 2 or 3 at maximum frown at baseline.

    Superiority analysis of active treatment versus placebo was carried out using a multivariate logistic regression model and adjusted for the stratification factors of gender and baseline severity score of glabellar lines at maximum frown measured by the ILA. The adjusted percentage of responders is presented for Cycle 1, Day 29.

    Measured: At Cycle 1, Day 29.

  2. Superiority Analysis of The Percentage of Responders Measured by the SSA at Maximum Frown at Cycle 1, Day 29 (DB Period).

    At baseline (Cycle 1, Day 1) and at Cycle 1, Day 29, subjects assessed the appearance of their glabellar lines at maximum frown using a 4-point categorical scale. The 4-point scale represents the severity of glabellar lines as Grade 0 (no wrinkles), Grade 1 (mild wrinkles), Grade 2 (moderate wrinkles) and Grade 3 (severe wrinkles). For the SSA, a responder was defined as having a severity grade of 0 or 1 at maximum frown at Cycle 1, Day 29, and a severity grade of 2 or 3 at maximum frown at baseline.

    Superiority analysis of active treatment versus placebo was carried out using a multivariate logistic regression model and adjusted for the stratification factors of gender and baseline severity score of glabellar lines at maximum frown measured by the ILA. The adjusted percentage of responders is presented for Cycle 1, Day 29.

    Measured: At Cycle 1, Day 29.

  3. Non-Inferiority Analysis of The Percentage of Responders Measured by the Investigator's Live Assessment (ILA) at Maximum Frown at Cycle 1, Day 29 (DB Period).

    At baseline (Cycle 1, Day 1) and at Cycle 1, Day 29, the Investigator assessed the appearance of the glabellar lines at maximum frown using a validated 4-point Photographic Scale of Glabellar Line Severity. This 4-point scale rated the severity of glabellar lines as Grade 0 (none), Grade 1 (mild), Grade 2 (moderate) and Grade 3 (severe). A responder was defined as having a severity grade of 0 or 1 at Cycle 1, Day 29, and a severity grade of 2 or 3 at maximum frown at baseline.

    Non Inferiority analysis of Dysport® versus Botox was carried out using a multivariate logistic regression model and adjusted for the stratification factors of gender and baseline severity score of glabellar lines at maximum frown measured by the ILA. The adjusted percentage of responders is presented for Cycle 1, Day 29.

    Measured: At Cycle 1, Day 29.

Secondary outcomes (3)
  1. The Percentage of Responders With Respect to Independent Reviewer's Assessment of Photographs of the Subject's Glabellar Lines at Maximum Frown at Cycle 1, Day 29 (DB Period).

    Photographs of the glabellar region of subjects were taken at maximum frown at baseline (Cycle 1, Day 1) and at Cycle 1, Day 29. Photographs were assessed by an Independent Experts Committee using a validated 4-point Photographic Scale of Glabellar Line Severity which rated the severity of glabellar lines as Grade 0 (none), Grade 1 (mild), Grade 2 (moderate) and Grade 3 (severe). The median of three readings by three independent reviewers was used in the analysis. A responder was defined as having a severity grade of 0 or 1 at Cycle 1, Day 29, and a severity grade of 2 or 3 at baseline.

    Superiority analysis of active treatment to placebo was carried out using a multivariate logistic regression model and adjusted for the stratification factors of gender and baseline severity score of glabellar lines at maximum frown measured by the ILA. The adjusted percentage of responders is presented for Cycle 1, Day 29.

    Measured: At Cycle 1, Day 29.

  2. Mean Subject's Global Assessment (SGA) Score at Cycle 1, Day 29 (DB Period).

    On Cycle 1, Day 29, subjects were asked to assess the change, since the last treatment administration, in the appearance of their glabellar lines using the following 9-point Global Assessment Scale: +4 =100% improvement; +3 =75% improvement; +2 =50% improvement; +1 =25% improvement; 0 =no change; -1 =25% worsening; -2 =50%worsening; -3 =75% worsening; -4 =100% worsening.

    The mean SGA score at Cycle 1, Day 29 is presented.

    Measured: At Cycle 1, Day 29.

  3. The Percentage of Responders With Respect to the SGA Score at Cycle 1, Day 29 (DB Period).

    On Cycle 1, Day 29, subjects were asked to assess the change, since the last treatment administration, in the appearance of their glabellar lines using the following 9-point Global Assessment Scale: +4 =100% improvement; +3 =75% improvement; +2 =50% improvement; +1 =25% improvement; 0 =no change; -1 =25% worsening; -2 =50% worsening; -3 =75% worsening; -4 =100% worsening. A responder, based on the SGA scale, was defined as having a grade of at least +2 (50% improvement).

    Superiority analysis of active treatment versus placebo was carried out using a multivariate logistic regression model and adjusted for the stratification factors of gender and baseline severity score of glabellar lines at maximum frown measured by the ILA. The adjusted percentage of responders is presented for Cycle 1, Day 29.

    Measured: At Cycle 1, Day 29.
