Deoxycholic Acid Injection Submental Fat (SMF) Magnetic Resonance Imaging (MRI) and Subject-reported Outcome Measures Study
Multicenter, Randomized, Double-blind, Placebo-controlled Study of ATX-101 (Sodium Deoxycholate Injection) Versus Placebo for the Reduction of Localized Subcutaneous Fat in the Submental Area (SMF) Using Magnetic Resonance Imaging (MRI) and a Battery of Clinician- and Subject-reported Measurements.

Measure Description |
Time Frame |
|---|---|---|
|
Change From Baseline in Clinician-Reported Submental Fat Rating Scale Scores
Time Frame: Baseline and 12 weeks after last treatment (up to 32 weeks after first treatment)
|
The CR-SMFRS score is based on the investigator's clinical evaluation of the participant, where submental fullness is scored on a 5-point ordinal scale (0-4) with 0 = absent, 1 = mild, 2 = moderate, 3 = severe, and 4 = extreme.
A negative change from Baseline indicates improvement.

Baseline and 12 weeks after last treatment (up to 32 weeks after first treatment)
|
|
Change From Baseline in Patient-Reported Submental Fat Scale Rating Scale (PR-SMFRS)
Time Frame: Baseline and 12 weeks after last treatment (up to 32 weeks after first treatment)
|
The PR-SMFRS is based on the participant's response to the question "How much fat do you have under your chin right now?" answered on a 5-point ordinal scale (0-4) with 0 = no chin fat at all, 1 = a slight amount of chin fat, 2 = a moderate amount of chin fat, 3 = a large amount of chin fat, and 4 = a very large amount of chin fat.
A negative change from Baseline indicates improvement.
|
Baseline and 12 weeks after last treatment (up to 32 weeks after first treatment)
|
|
Change From Baseline in Patient-Reported Submental Fat Impact Scale (PR-SMFIS)
Time Frame: Baseline and 12 weeks after last treatment (up to 32 weeks after first treatment)
|
The PR-SMFIS assesses 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 is 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 0 is a positive outcome and 10 is a negative outcome.
A negative change from Baseline indicates improvement.
