Long-term 24-month Follow-up Study on Safety and Maintenance of Efficacy of ATX-101 (Sodium Deoxycholate Injection)

September 21, 2018 updated by: Allergan

Long-term, Follow-up Study of Subjects Who Completed Phase III Trials ATX-101-10-16 or ATX-101-10-17 (Sodium Deoxycholate Injection) for the Reduction of Localized Subcutaneous Fat in the Submental Area

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
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.
LTFU Baseline (Month 0) to Month 24
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.
LTFU Baseline (Month 0) to Month 24

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
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
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. 2- grade response=At least a 2-grade reduction from original study baseline in the CR-SMFRS assessment.
LTFU Baseline (Month 0) to Month 24
Patient-Reported Submental Fat Impact Scale (PR-SMFIS)
Time Frame: LTFU Baseline (Month 0) to Month 24
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.
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
Time Frame: LTFU Baseline (Month 0) to Month 24
Participants who had at least a 1-grade reduction in both the CR-SMFRS and PR-SMFRS from the original baseline value in the predecessor study were defined as composite SMFRS-1 responders.
LTFU Baseline (Month 0) to Month 24
Percentage of Participants with at Least One Treatment-Emergent Adverse Event (TEAE)
Time Frame: Up to approximately 24 months
An adverse event was any undesirable medical occurrence or worsening of an existing condition, irrespective of whether the event was considered treatment-related. A treatment-emergent adverse event was defined as an adverse event with an onset that occurs after receiving treatment.
Up to approximately 24 months
Percentage of Participants with Treatment-emergent Adverse Events Associated with the Treatment Area (Drug-related)
Time Frame: Up to approximately 24 months
An adverse event was any undesirable medical occurrence or worsening of an existing condition, irrespective of whether the event was considered treatment-related. A treatment-emergent adverse event was defined as an adverse event with an onset that occurs after receiving treatment.
Up to approximately 24 months
Percentage of Participants with Treatment-emergent Adverse Events of Special Interest (AESIs)
Time Frame: Up to approximately 24 months
An adverse event was any undesirable medical occurrence or worsening of an existing condition, irrespective of whether the event was considered treatment-related. A treatment-emergent adverse event was defined as an adverse event with an onset that occurs after receiving treatment. AESIs for this study are common treatment reactions (consistently reported for overall AEs, treatment area-related AEs, or study-drug-related AEs) that were observed in earlier deoxycholic acid injection studies and identified as likely to be related to the injection procedure.
Up to approximately 24 months
