Moderate or Severe Submental Fullness
Conditions
Brief summary
To evaluate the safety and potential efficacy of deoxycholic acid injection compared to placebo for the reduction of submental fat (fat below the chin).
Detailed description
The trial included an initial cohort (3 participants in each arm) to evaluate safety followed by expansion to a second, larger cohort if adequate safety was determined in the initial cohort. Data from both cohorts was pooled for analysis.

| Number of Participants With Adverse Events | From the first dose of study drug until 12 weeks after the last dose (up to 24 weeks after first treatment). | The investigator determined the relationship of each adverse event to the administration of study drug. Severity of adverse events was determined using the following scale: * Mild: The participant is aware of a sign or symptom, but it is easily tolerated * Moderate: Discomfort or interference with usual activity * Severe: Incapacitating, with inability to engage in usual activity. A serious AE (SAE) was defined as an event that may constitute a significant medical hazard or side-effect, regardless of the investigator or sponsor's opinion regarding relatedness to study material. Serious events included, but were not limited to, any event that: * was fatal * was life-threatening * required inpatient hospitalization or prolongation of existing hospitalization * resulted in persistent or significant disability/incapacity * was a congenital anomaly/birth defect * other significant medical hazard |

| Percentage of Participants With a Response in the Subject Global Improvement Rating | 4 weeks after last treatment (up to 16 weeks after first dose) | Participants were asked to rate their total improvement or worsening in the appearance and physical feeling of their chin and neck area since before they received study treatment, whether or not they believed it was due to study treatment or to any other cause. 0 = Very much worse, 1 = Much worse, 2 = Minimally worse, 3 = No change, 4 = Minimally improved, 5 = Much improved, 6 = Very much improved.

Recruitment details
The study was conducted at 6 study centers: 1 in the United Kingdom, 2 in Canada, and 3 in Australia.
Pre-assignment details
Enrollment was conducted in 2 stages, an initial cohort in which preliminary safety and tolerability were evaluated and a second cohort (contingent cohort), which was enrolled after it had been determined that acceptable safety and tolerability were observed in the initial cohort. Participants from both cohorts were pooled for analysis.

Outcome results
Primary
Number of Participants With Adverse Events
The investigator determined the relationship of each adverse event to the administration of study drug. Severity of adverse events was determined using the following scale: * Mild: The participant is aware of a sign or symptom, but it is easily tolerated * Moderate: Discomfort or interference with usual activity * Severe: Incapacitating, with inability to engage in usual activity. A serious AE (SAE) was defined as an event that may constitute a significant medical hazard or side-effect, regardless of the investigator or sponsor's opinion regarding relatedness to study material. Serious events included, but were not limited to, any event that: * was fatal * was life-threatening * required inpatient hospitalization or prolongation of existing hospitalization * resulted in persistent or significant disability/incapacity * was a congenital anomaly/birth defect * other significant medical hazard
Time frame: From the first dose of study drug until 12 weeks after the last dose (up to 24 weeks after first treatment).
Population: Safety and Modified Intent to Treat (mITT) population including all randomized participants who received at least 1 dose of study drug and who had at least 1 post-baseline observation.
