结局指标
主要结局
Percentage of Participants With at Least a 1-Grade Reduction (Improvement) at 12 Weeks From Last Treatment Based on Both the Clinician-Reported Submental Fat Rating Scale (CR-SMFRS) and Patient-Reported Submental Fat Rating Scale (PR-SMFRS) Assessments
时间窗: Baseline and up to Week 32 (12 weeks after last treatment)
The investigator evaluated the participant's chin and neck area using the Clinician-Reported Submental Fat Rating Scale (a 5-point scale) where: 0=absent submental convexity (best) to 4= extreme submental convexity (worst). The participant evaluated their chin and neck area using the Patient-Reported Submental Fat Rating Scale (a 5-point scale) where: 0=no chin fat at all (best) to 4= a very large amount of chin fat (worst).
Percentage of Participants With at Least a 2-Grade Reduction (Improvement) at 12 Weeks From Last Treatment Based on Both the Clinician-Reported Submental Fat Rating Scale (CR-SMFRS) and Patient-Reported Submental Fat Rating Scale (PR-SMFRS) Assessments
时间窗: Baseline and up to Week 32 (12 weeks after last treatment)
The investigator evaluated the participant's chin and neck area using the Clinician-Reported Submental Fat Rating Scale (a 5-point scale) where: 0=absent submental convexity (best) to 4= extreme submental convexity (worst). The participant evaluated their chin and neck area using the Patient-Reported Submental Fat Rating Scale (a 5-point scale) where: 0=no chin fat at all (best) to 4= a very large amount of chin fat (worst).
Percentage of Participants With at Least a 2-Grade Reduction (Improvement) at 12 Weeks From Last Treatment Based on the Clinician-Reported Submental Fat Rating Scale (CR-SMFRS)
时间窗: Baseline and up to Week 32 (12 weeks after last treatment)
The investigator evaluated the participant's chin and neck area using the CR-SMFRS 5-point scale where: 0=absent submental convexity (best) to 4= extreme submental convexity (worst).
Percentage of Participants With at Least a 1-Grade Reduction (Improvement) at 12 Weeks From Last Treatment Based on Patient-Reported Submental Fat Rating Scale (PR-SMFRS)
时间窗: Baseline and up to Week 32 (12 weeks after last treatment)
The participant evaluated their chin and neck area using the PR-SMFRS 5-point scale where: 0=no chin fat at all (best) to 4= a very large amount of chin fat (worst).
Percentage of Participants With at Least a 2-Grade Reduction (Improvement) at 12 Weeks From Last Treatment Based on Patient-Reported Submental Fat Rating Scale (PR-SMFRS)
时间窗: Baseline and up to Week 32 (12 weeks after last treatment)
The participant evaluated their chin and neck area using the PR-SMFRS 5-point scale where: 0=no chin fat at all (best) to 4= a very large amount of chin fat (worst).
Change From Baseline in Submental Skin Laxity Grade Scale (SMSLG)
时间窗: Baseline and up to Week 32 (12 weeks after last treatment)
The SMSLG is an integration of three features: skin wrinkling, adherence to underlying neck structures (bone and muscle) and redundancy (horizontal and vertical folds). Each grade (1=none, 2=mild, 3=moderate and 4=severe) defines the maximal allowed limit for skin wrinkling, adherence to underlying structures and redundancy.
Percentage of Participants With at Least a 1-Grade Reduction (Improvement) at 12 Weeks From Last Treatment Based on the Clinician-Reported Submental Fat Rating Scale (CR-SMFRS)
时间窗: Baseline and up to Week 32 (12 weeks after last treatment)
The investigator evaluated the participant's chin and neck area using the CR-SMFRS 5-point scale where: 0=absent submental convexity (best) to 4= extreme submental convexity (worst).
