General information about the trial
|
|||
Main objective of the trial |
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 or ATX-101-10-17 were enrolled in this non-treatment observational follow-up study to further evaluate safety and efficacy.

End point description |
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. The full analysis set included all participants who received a clearly identifiable treatment in the previous study and had at least one visit in the LTFU study. Participants were included in the analysis according to their randomized treatment assignment. Missing values at Month 24 were imputed using LOCF. Non-responders at LTFU baseline in each treatment group (including placebo) were not included in the analysis.

End point description |
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. A positive change from Baseline indicates improvement. The full analysis set included all participants who received a clearly identifiable treatment in the previous study and had at least one visit in the LTFU study. Participants were included in the analysis according to their randomized treatment assignment. Missing values at Month 24 were imputed using last observation carried forward (LOCF). Non-responders at LTFU baseline in each treatment group (including placebo) were not included in the analysis.

Patient-Reported Submental Fat Impact Scale (PR-SMFIS) | ||||||||||||||||||||||||
End point description |
The PR-SMFIS assessed the impact of submental fat on self-perception of 6 emotional and visual characteristics related to the appearance of submental fullness (unhappy, bothered, self-conscious, embarrassed, look older, and look overweight) as evaluated by the participant. Each item was rated on an 11-point numeric scale from 0 to 10. Scores for the 6 items were averaged to generate a PR-SMFIS total scale score ranging from 0 to 10 where low scores reflect a positive impact and high scores reflect a negative impact. The full analysis set included all participants who received a clearly identifiable treatment in the previous study and had at least one visit in the LTFU study. Participants were included in the analysis according to their randomized treatment assignment. Here, "n" represents the number of participants evaluated at specific time points.
