Primary Outcome Measures

Name	Time	Method
Percentage of Participants with Achievement of ≥ 1-grade improvement from baseline as rated by investigator using the Clinician Glabellar Lines Scale.	Day 1 to Day 30	The Clinician Glabellar Lines Scale is a four point scale used to assess the severity of Glabellar Lines at maximum contraction ranging from 0 - None to 3 - Severe
Percentage of Participants With Adverse Events (AEs)	Day 1 to Day 270	An adverse event (AE) is defined as any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product which does not necessarily have a causal relationship with this treatment. The investigator assesses the relationship of each event to the use of study. A serious adverse event (SAE) is an event that results in death, is life-threatening, requires or prolongs hospitalization, results in a congenital anomaly, persistent or significant disability/incapacity or is an important medical event that, based on medical judgment, may jeopardize the participant and may require medical or surgical intervention to prevent any of the outcomes listed above. Treatment-emergent adverse events/treatment-emergent serious adverse events (TEAEs/TESAEs) are defined as any event that began or worsened in severity on or after the first dose of study drug.

Secondary Outcome Measures

Name	Time	Method
Percentage of Participants with Achievement of None or Mild as rated by investigator using the Clinician Glabellar Lines Scale.	Day 1 to Day 30	The Clinician Glabellar Lines Scale is a four point scale used to assess the severity of Glabellar Lines at maximum contraction ranging from 0 - None to 3 - Severe
Percentage of Participants with Achievement of improvement per the Facial Lines Satisfaction Questionnaire Impact domain, among subjects with baseline scores of 14 points or greater.	Day 1 to Day 30	The Facial Line Satisfaction Questionnaire assesses treatment expectations, treatment satisfaction, and psychosocial impact of GL from the subject perspective.
Percentage of Participants with Achievement of satisfaction with treatment per the Facial Line Satisfaction Questionnaire Item 5.	Day 1 to Day 60	The Facial Line Satisfaction Questionnaire assesses treatment expectations, treatment satisfaction, and psychosocial impact of GL from the subject perspective.
