Overview
Brief Summary
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.

Eligibility Criteria
Inclusion Criteria
- •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
- •Willingness to comply with the schedule and procedures of the study
Exclusion Criteria
- •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)

Outcomes
Primary Outcomes
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
Time Frame: 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
Time Frame: 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.
Secondary Outcomes
- Percentage of Participants Maintaining Clinician-Reported Submental Fat Rating Scale (CR-SMFRS) 2-Grade Response During the 24 Months of Follow up, i.e. % of Participants who were CR-SMFRS 2-Grade Responders at both LTFU Baseline and at 24-Month Visit(LTFU Baseline (Month 0) to Month 24)
- Patient-Reported Submental Fat Impact Scale (PR-SMFIS)(LTFU Baseline (Month 0) to Month 24)
- Percentage of Participants Maintaining Composite SMFRS 1-Grade Response During the 24 Months of Follow up, i.e. % of Participants who were Composite SMFRS 1-Grade Responders at both LTFU Baseline and at 24-Month Visit(LTFU Baseline (Month 0) to Month 24)
- Percentage of Participants with at Least One Treatment-Emergent Adverse Event (TEAE)(Up to approximately 24 months)
- Percentage of Participants with Treatment-emergent Adverse Events Associated with the Treatment Area (Drug-related)(Up to approximately 24 months)
- Percentage of Participants with Treatment-emergent Adverse Events of Special Interest (AESIs)(Up to approximately 24 months)
