What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Number of Participants With Adverse Events
Time Frame: From the first dose of study drug until 12 weeks after the last dose (up to 24 weeks after first treatment).
|
The investigator determined the relationship of each adverse event to the administration of study drug. Severity of adverse events was determined using the following scale:
A serious AE (SAE) was defined as an event that may constitute a significant medical hazard or side-effect, regardless of the investigator or sponsor's opinion regarding relatedness to study material. Serious events included, but were not limited to, any event that:
|
From the first dose of study drug until 12 weeks after the last dose (up to 24 weeks after first treatment).
|
Number of Participants With Clinically Significant Changes From Baseline in Laboratory Values, Weight, Vital Signs, and Physical Examinations
Time Frame: From the first dose of study drug until 12 weeks after the last dose (up to 24 weeks after first treatment).
|
From the first dose of study drug until 12 weeks after the last dose (up to 24 weeks after first treatment).
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change From Baseline in Submental Fat (SMF) Rating Scale Score
Time Frame: Baseline and 4 weeks after last treatment (up to 16 weeks after first dose)
|
The SMF rating scale score is based on the investigator's clinical evaluation of the participant, where submental fullness is scored on a 5-point ordinal scale (0-4) with 0 = absent, 1 = mild, 2 = moderate, 3 = severe, and 4 = extreme. A negative change from Baseline indicates improvement. |
Baseline and 4 weeks after last treatment (up to 16 weeks after first dose)
|
Percentage of Participants With a Response in the Subject Global Improvement Rating
Time Frame: 4 weeks after last treatment (up to 16 weeks after first dose)
|
Participants were asked to rate their total improvement or worsening in the appearance and physical feeling of their chin and neck area since before they received study treatment, whether or not they believed it was due to study treatment or to any other cause. 0 = Very much worse, 1 = Much worse, 2 = Minimally worse, 3 = No change, 4 = Minimally improved, 5 = Much improved, 6 = Very much improved. Response is defined as any improvement, ie, a global improvement rating of 4, 5, or 6. |
4 weeks after last treatment (up to 16 weeks after first dose)
|
Change From Baseline in Skin Laxity Rating
Time Frame: Baseline and Week 4, Week 8, Week 12, Week 16 (4 weeks after last treatment) and Week 24 (12 weeks after last treatment)
|
Skin laxity assessment was based on clinical evaluation and palpation of the submental area on the following scale: 1 = no laxity; 2 = minimal laxity; 3 = moderate laxity; 4 = very lax. A negative change from Baseline indicates improvement. |
Baseline and Week 4, Week 8, Week 12, Week 16 (4 weeks after last treatment) and Week 24 (12 weeks after last treatment)
|
Change From Baseline in the Cervicomental Angle
Time Frame: Baseline and 4 weeks after last treatment (up to 16 weeks after first dose)
|
The cervicomental angle was measured using a profile view photograph obtained at each visit.
A goniometer was used to determine the angle.
Cervicomental angle measurements less than 80 degrees are excluded, due to error in measurement.
|
Baseline and 4 weeks after last treatment (up to 16 weeks after first dose)
|
Change From Baseline in Subject Satisfaction With Appearance Rating Scale
Time Frame: Baseline and 4 weeks after last treatment (up to 16 weeks after first dose)
|
The Subject Satisfaction with Appearance Rating Scale assesses participants' satisfaction with their appearance in association with the face and chin on a 7-point scale from 0 to 6 where 0 = Extremely dissatisfied, 1 = Dissatisfied, 2 = Slightly dissatisfied, 3 = Neither satisfied nor dissatisfied, 4 = Slightly satisfied, 5 = Satisfied and 6 = Extremely satisfied. A positive change from Baseline indicates improvement. |
Baseline and 4 weeks after last treatment (up to 16 weeks after first dose)
|
Percentage of Participants With an SMF Response
Time Frame: Baseline and 4 weeks after last treatment (up to 16 weeks after first dose)
|
Response is defined as a participant with at least a 1-grade improvement in SMF Rating Scale score at Week 16 from Baseline.
The SMF rating scale score is based on the investigator's clinical evaluation of the participant, where submental fullness is scored on a 5-point ordinal scale (0-4) with 0 = absent, 1 = mild, 2 = moderate, 3 = severe, and 4 = extreme.
|
Baseline and 4 weeks after last treatment (up to 16 weeks after first dose)
|
Change From Baseline to Each Visit in Submental Fat (SMF) Rating Scale Score
Time Frame: Baseline and Week 4, Week 8, Week 12, Week 16 (4 weeks after last treatment) and Week 24 (12 weeks after last treatment)
|
The SMF rating scale score is based on the investigator's clinical evaluation of the participant, where submental fullness is scored on a 5-point ordinal scale (0-4) with 0 = absent, 1 = mild, 2 = moderate, 3 = severe, and 4 = extreme. A negative change from Baseline indicates improvement. |
Baseline and Week 4, Week 8, Week 12, Week 16 (4 weeks after last treatment) and Week 24 (12 weeks after last treatment)
|
Visual Analogue Scale Pain Intensity Rating
Time Frame: Approximately 60 minutes after completion of each treatment session at Week 0, Week 4, Week 8 and Week 12
|
Participants rated pain associated with the submental area on a 100 mm horizontal axis ranging from 0 (no pain) to 100 (most severe pain possible)
|
Approximately 60 minutes after completion of each treatment session at Week 0, Week 4, Week 8 and Week 12
