入选标准
- •Males and females, 65 to 75 years of age
- •Stable Body Weight
- •Dissatisfaction with the submental area expressed by participants
- •Acceptable volume of submental fat graded by clinician
- •BMI of ≤40.0 kg/m^2
- •Signed informed consent (ICF)
- •SMF rating of 2 or 3 by clinician and patient
排除标准
- •No prior intervention for submental fat (SMF) (eg liposuction, surgery or lipolytic agents)
- •Absence of clinically significant health problems
- •Anatomical features for which reduction in SMF may result in aesthetically unacceptable outcome, judged by clinician
- •History of trauma associated with the chin or neck areas that in the judgment of the investigator may affect evaluation of safety or efficacy
- •Body mass index of ≥40.0 kg/m^2
研究组 & 干预措施
Placebo
Participants received placebo administered in 0.2 mL subcutaneous (SC) injections, up to 10 milliliters (mL) per treatment session at intervals of approximately 1 month for up to a maximum of 6 treatments.
干预措施: Placebo (Drug)
ATX-101 deoxycholic acid injection
Participants received deoxycholic acid 2 mg/cm^2 administered in 0.2 mL SC injections, up to 10 mL per treatment session at intervals of approximately 1 month for up to a maximum of 6 treatments.
干预措施: ATX-101 (Drug)
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 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).
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 the 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 the 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.
