简要总结
The objective of this non-treatment, placebo-controlled, observational, 24-month follow-up study was to evaluate the long-term efficacy and safety of subcutaneous (SC) injections of deoxycholic acid (ATX-101) in the submental area. No treatment was administered in this study. Participants who previously received deoxycholic acid injections in studies ATX-101-10-16 [NCT01305577] or ATX-101-10-17 [NCT01294644] were enrolled in this non-treatment observational follow-up study to further evaluate safety and efficacy.

入选标准
- •Signed written informed consent before any study-related activities are carried out
- •Any participant who successfully completed the final visit (visit 7) of a phase 3 clinical trial, ATX-101-10-16 or ATX-101-10-17 for the reduction of submental fat, i.e. subjects must have at least one study treatment administered and have completed the predecessor study up to visit 7

排除标准
- •Participants who, since the completion of the prior phase 3 study ATX-101-10-16 or ATX-101-10-17, have had or who are undergoing treatment that may affect the evaluation of the submental area (e.g. - but not limited to - long-term treatment with systemic corticosteroids, liposuction, surgery or other lipolytic treatment in the submental area, treatment with radio frequency, laser procedures, chemical peels, dermal fillers in the neck or chin area or botulinum toxin injections in the neck or chin area)

结局指标
主要结局
Percentage of Participants Maintaining Clinician-Reported Submental Fat Rating Scale (CR-SMFRS) 1-Grade Response During the 24 Months of Follow up, i.e. % of Participants who were CR-SMFRS 1-Grade Responders at both LTFU Baseline and at 24-Month Visit
时间窗: LTFU Baseline (Month 0) to Month 24
The CR-SMFRS was based on the investigator's clinical evaluation of the participant's chin and neck area using a 5-point ordinal scale (0 to 4) with 0=Absent Submental Convexity: no localized submental fat evident; 1=Mild Submental Convexity: minimal, localized submental fat; 2=Moderate Submental Convexity: prominent, localized submental fat; 3=Severe Submental Convexity; a marked amount of chin fat; and 4=Extreme Submental Convexity: marked, localized submental fat. 1-grade response=At least a 1-grade reduction from original study baseline in the CR-SMFRS assessment.
Percentage of Participants with Maintenance of Response as Assessed by the Subject Satisfaction Rating Scale (SSRS) During the 24 Months of Follow up, i.e. % of Participants who were SSRS Responders at both LTFU Baseline and at 24-Month Visit
时间窗: LTFU Baseline (Month 0) to Month 24
For the SSRS, the participant was asked to answer the question: "Considering your appearance in association with your face and chin, how satisfied do you feel with your appearance at the present time?" using a 7-point scale: 0=Extremely dissatisfied, 1=Dissatisfied, 2=Slightly dissatisfied, 3=neither satisfied nor dissatisfied, 4=Slightly satisfied, 5=Satisfied, and 6=Extremely satisfied. SSRS responder was a participant whose response was ≥ 4.
