Number of Participants With Treatment-Emergent Adverse Events (TEAEs)
Day 1 to Day 180

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 casual relationship with this treatment. The investigator assesses the relationship of each event to the use of the 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 the study drug.

Percentage of Participants Who Achieved Masseter Muscle Prominence Scale (MMPS) Grade ≤ 3 at Day 90 as Assessed by the Investigator

Number of Participants With at Least One Treatment-emergent Adverse Event (TEAE)
First dose (Day 1) to the End of Study (Up to Day 180)

An adverse event (AE) is any untoward medical occurrence in a patient or clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of study intervention. A TEAE is an AE that occurs or worsens after receiving study drug.

Change From Baseline in Systolic Blood Pressure
Baseline (Day 1) to the End of Study (Up to Day 180)
Change From Baseline in Diastolic Blood Pressure

Stage 2: Change From Baseline in the Average Number of Urinary Incontinence Episodes (UIEs) Per Day
Baseline (3 consecutive days during Day -14 to Day -1) to 3 consecutive days in the Week prior to Week 12

The participant recorded urinary incontinence (lack of voluntary control over urination) in a 3-day bladder diary. The average number of UIEs per day is the average of the 3-day diary entries. A negative change from Baseline indicates improvement. Baseline is defined as the last non-missing assessment before the first dose of study treatment. An analysis of covariance (ANCOVA) model was used for analyses.

Number of Participants With at Least One Treatment-Emergent Adverse Event (TEAEs) in the Treatment Period
Up to End of Study (Stage 1: Up to 114 days and Stage 2: Up to 35.1 weeks)

An adverse event (AE) is any untoward medical occurrence in a participants or clinical study investigation participant administered a pharmaceutical product and which does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal product, whether or not related to the medicinal product. A TEAE is an AE that occurs or worsens after receiving study drug.

Change From Baseline in the 7-Day Average Daily Pain Score Using an 11-Point Scale

Baseline Values for the Clinic 10-Item Montgomery-Asberg Depression Rating Scale (MADRS) Total Score
Baseline

The MADRS is a 10-item scale completed by clinic personnel that assesses the subject's symptoms of depression.
