Outcomes

Primary Outcomes

Number of Participants With a Response Defined as Change in IGA-C (Investigators Global Assessment) Score by at Least 2 Ordinals From Baseline to Week 4

Investigators Global Assessment of the Crow's Feet Wrinkle Scale where severity is scored between 0-4 (0=absent; 4=severe). Response is defined as change by at least two ordinals from Baseline to Week 4.

Time frame: Week 4

Secondary Outcomes

Total Number of Observations With a Response Defined as Change ≥2 in IGA-C and SSA-C Score at Any Post Baseline Visit

Total number of observations with a change in the Investigators Global Assessment on Contraction, IGA-C, and the Subject Self-Assessment on Contraction, SSA-C, using the Crow's Feet Wrinkle Scale, where severity is scored between 0-4 (0=absent; 4=severe). To count, a "responder" is defined as a change by at least two ordinals in both assessments. The observation period includes all post-baseline visits from Week 1 to Week 26.

Time frame: Week 1, 2, 4, 8,12,18, and 26

Total Number of Observations With a Response Defined as Change in SSA-C Score ≥ 2 at Any Time Between Week 4 and Week 12

Total number of observations with a change by at least two ordinals in the Subjects Self-Assessment on Contraction, SSA-C, using the Crow's Feet Wrinkle Scale, where severity is scored between 0-4 (0=absent; 4=severe). To count, a "responder" is defined as an improvement ≥ 2 score points. The observation period covers the time time of expected peak efficacy from Week 4 to Week 12.
