Description

Inclusion Criteria:

  • For glabellar lines (GL) indication: participant must have moderate or severe GL at maximum furrow as assessed by both the investigator and participant using the AGLSS at Screening and Baseline (Day 1) visits.
  • Participant must be in good health as per investigator's judgment based on medical history, physical examination, vital sign measurements, 12-lead electrocardiogram (ECG) parameters, clinical laboratory evaluations, and neurological assessment.
  • In the investigator's opinion, participant must not have a condition or be in a situation that may put the participant at significant risk, may confound the study results, or may interfere significantly with the participant's participation in the study.

Exclusion Criteria:

  • For GL Indication: Severe GL at rest as assessed by the investigator using the AGLSS at Screening or Baseline (Day 1).
  • History of immunization to any botulinum neurotoxin serotype or hypersensitivity to any botulinum neurotoxin serotype or any other constituents of the study drug or its excipients
  • Active infection or dermatological condition at the treatment injection sites.
  • Medical condition that may put the subject at increased medical risk with exposure to botulinum toxin, including diagnosed myasthenia gravis, Lambert-Eaton syndrome, amyotrophic lateral sclerosis, or any other condition that might interfere with neuromuscular function

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Number of Participants with Adverse Events (AEs)
Time Frame: Up to Day 150

An AE is defined as any untoward medical occurrence in a patient or clinical investigation in which a participant is administered a pharmaceutical product which does not necessarily have a causal relationship with this treatment.

Up to Day 150
Percentage of Participants Achieving None or Mild on the Investigator-Assessed Allergan Glabellar Lines Severity Scale (AGLSS)
Time Frame: Day 7

Achievement of None or Mild on the investigator-assessed AGLSS. The AGLSS is a validated 4-point scale (0=None through 3=Severe) used to assess glabellar line severity. A response of None or Mild indicates improvement in glabellar line severity.

Day 7

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percentage of Participants Achieving None or Mild on the Subject-Assessed AGLSS
Time Frame: Day 7

Achievement of None or Mild on the subject-assessed AGLSS. The AGLSS is a validated 4-point scale (0=None through 3=Severe) used to assess glabellar line severity. A response of None or Mild indicates improvement in glabellar line severity.

Day 7
Duration Area Under the Curve (AUC) for Time-Averaged Response Based on Achievement of None or Mild on the Investigator-Assessed AGLSS
Time Frame: Up to Day 150

Duration AUC (area under the curve) for time-averaged response based on achievement of None or Mild on the investigator-assessed AGLSS. The AGLSS is a validated 4-point scale (0=None through 3=Severe). This endpoint measures the duration of treatment effect over time.

Up to Day 150
Onset Area Under the Curve (AUC) for Time-Averaged Response Based on Achievement of None or Mild on the Investigator-Assessed AGLSS
Time Frame: Up to to Day 7

Onset AUC (area under the curve) for time-averaged response based on achievement of None or Mild on the investigator-assessed AGLSS. The AGLSS is a validated 4-point scale (0=None through 3=Severe). This endpoint measures the rapidity of onset of treatment effect.

Up to to Day 7
