Study Endpoints

Primary Endpoints

Composite Achievement of MMP Severity Improvement and at Least a 2-Grade Improvement from Baseline by Both Investigator-Rated MMPS and Participant-Rated MMPS-P
Day 90

The investigator and participant each assessed the participant's Masseter Muscle Prominence (MMP) using the Masseter Muscle Prominence Scale (MMPS) and the Masseter Muscle Prominence Scale-Participant (MMPS-P), respectively. Both are a 5-point masseter muscle severity scale with grades ranging from 1 (minimal/not at all noticeable) to 5 (very marked/extremely noticeable).

Number of Participants with Adverse Events (AEs)
Baseline to Day 360

An 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.

Percentage of Participants who Achieved 'None' or 'Mild' on Facial Wrinkle Scale with Asian Photonumeric Guide (FWS-A) According to the Investigator Assessment of Forehead Lines (FHL) Severity
Day 30

The investigator assesses FHL severity using the FWS-A 4-point scale ranging from 0=None to 3=Severe.

Percentage of Participants who Achieved 'None' or 'Mild' on FWS-A According to the Participant Assessment of FHL Severity
Day 30

The participant assesses FHL severity using the FWS-A 4-point scale ranging from 0=None to 3=Severe.

Percentage of Participants who Achieve >= 2-Grade Improvement on Investigator-Rated Masseter Muscle Prominence Scale (MMPS)
Baseline to Day 90

The MMPS is a photonumeric scale encompassing visual inspection of the masseter muscles as performed by the investigator, where the masseter muscle prominence (MMP) is rated at rest, by separately evaluating the left and right side of the participant's face. The evaluation is on a 5-grade scale where 1 = the masseter muscle prominence is minimal and 5 = the masseter muscle prominence is very marked.

Achievement of 2-grade or more improvement from baseline on the Masseter Muscle Prominence Scale (MMPS) as assessed by the Investigator
Day 90

The investigator assessed the severity of the participant's MMP using the MMPS 5-point scale where: 1=minimal (best), 2=mild, 3=moderate, 4=marked, and 5=very marked (worst).

Achievement of 2-grade or more improvement from baseline on the Masseter Muscle Prominence Scale - Participant (MMPS-P) as assessed by the Participant
Day 90

The participant assessed the severity of their MMP using the MMPS-P 5-point scale where: 1=not at all pronounced (best), 2=mildly pronounced, 3=moderately pronounced, 4=pronounced, and 5=very pronounced (worst).

Change From Study Baseline in Number of Episodes of Urinary Incontinence in Treatment Cycle 1
Study Baseline, Week 12

Urinary incontinence is defined as involuntary loss of urine as recorded in a patient bladder diary in the 3 consecutive days prior to the study visit in Treatment Cycle 1. The number of incontinence episodes are averaged daily during this period. A negative number change from baseline indicates an improvement and a positive number change from baseline indicates a worsening.

Percentage of Patients With 100% Reduction in Incontinence Episodes in Treatment Cycle 1
Study Baseline, Week 12

Urinary incontinence is defined as involuntary loss of urine as recorded in a patient bladder diary in the 3 consecutive days prior to the study visit in Treatment Cycle 1. The number of incontinence episodes are averaged daily during this period and compared to baseline to determine 100% reduction in episodes.

Change From Baseline in Tremor Disability Scale-Revised (TREDS-R) Total Score Across 7 Unilateral Items
Week 24

Tremor Disability Scale-Revised (TREDS-R) is a scale to assess activities of daily living (ADL) through a self-questionnaire asking participants to rate how easy or difficult it is to perform a particular activity. The scale consists of 20 items with each item rated on a scale of 1 (able to do the activity without difficulty) to 4 (cannot do the activity by yourself). 7 items included in this subset will be: use a spoon to drink soup, hold a cup of tea, pour milk from a bottle or carton, dial a telephone, pick up your change in a shop, insert an electric plug into a socket, unlock your front door with a key.

Number of Participants with Treatment Emergent Adverse Events (AEs)
Up to approximately 36 weeks

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.

Change in Average Daily Worst Bladder Pain
Baseline (Week 0) to Week 6

Daily worst bladder pain will be assessed on the 11-point (0-10) numeric rating scale where 0 = no pain and 10 = the worst pain possible.

Number of Participants with Potential Clinically Significant (PCS) changes in vital signs
Baseline (Day 1) to Final Visit (up to Day 97)

Unique number of participants who experience one or more Potential Clinically Significant (PCS) change in vital signs from the Baseline visit.

Number of Participants with Potential Clinically Significant (PCS) changes in physical exams
Baseline (Day 1) to Final Visit (up to Day 97)

Unique number of participants who experience one or more Potential Clinically Significant (PCS) change in physical exams from the Baseline visit.

Number of Participants with injection site pain/discomfort.
Baseline (Day 1)

Unique number of participants who experience injection site pain and/or discomfort at the injection site during administration of treatment.

Secondary Endpoints

Percentage of Participants who Responded as "Very satisfied" or "Satisfied" on the Lower Facial Shape Questionnaire - Treatment Satisfaction Assessment (LFSQ-TXSAT)
Day 90
Percentage of Participants who Responded as "Not at all bothered" or "A little bothered" on the Bother Impact Assessment for Masseter Muscle Prominence (BIA-MMP)
Day 90
Change from Baseline in Lower Facial Shape Questionnaire-Impact Assessment (LFSQ-IA) Summary Score
