Brief summary

Phase 2 trial to evaluate the safety and potential efficacy of one concentration of deoxycholic acid injection, given in three dosing paradigms, compared to placebo for the reduction of submental fat (fat beneath the chin).

Interventions

Formulated as an injectable solution containing deoxycholic acid at a concentration of 10 mg/mL.

Design outcomes

Primary

MeasureTime frameDescription
Number of Participants With Adverse EventsFrom 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
Number of Participants With Clinically Significant Changes From Baseline in Laboratory Values, Weight, Vital Signs, and Physical ExaminationsFrom the first dose of study drug until 12 weeks after the last dose (up to 24 weeks after first treatment).

Secondary

MeasureTime frameDescription
Percentage of Participants With a Response in the Subject Global Improvement Rating4 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. Response is defined as any improvement, ie, a global improvement rating of 4, 5, or 6.
Percentage of Participants With an SMF ResponseBaseline and 4 weeks after last treatment (up to 16 weeks after first dose)Response is defined as a participant with at least a 1-grade improvement in SMF Rating Scale score at Week 16 from Baseline. The SMF rating scale 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.
Change From Baseline in Skin Laxity RatingBaseline and Week 4, Week 8, Week 12, Week 16 (4 weeks after last treatment) and Week 24 (12 weeks after last treatment)Skin laxity assessment was based on clinical evaluation and palpation of the submental area on the following scale: 1 = no laxity; 2 = minimal laxity; 3 = moderate laxity; 4 = very lax. A negative change from Baseline indicates improvement.
Change From Baseline in Submental Fat (SMF) Rating Scale ScoreBaseline and 4 weeks after last treatment (up to 16 weeks after first dose)The SMF rating scale 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.
Change From Baseline in the Cervicomental AngleBaseline and 4 weeks after last treatment (up to 16 weeks after first dose)The cervicomental angle was measured using a profile view photograph obtained at each visit. A goniometer was used to determine the angle. Cervicomental angle measurements less than 80 degrees are excluded, due to error in measurement.
Visual Analogue Scale Pain Intensity RatingApproximately 60 minutes after completion of each treatment session at Week 0, Week 4, Week 8 and Week 12Participants rated pain associated with the submental area on a 100 mm horizontal axis ranging from 0 (no pain) to 100 (most severe pain possible)
Change From Baseline to Each Visit in Submental Fat (SMF) Rating Scale ScoreBaseline and Week 4, Week 8, Week 12, Week 16 (4 weeks after last treatment) and Week 24 (12 weeks after last treatment)The SMF rating scale 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.
Change From Baseline in Subject Satisfaction With Appearance Rating ScaleBaseline and 4 weeks after last treatment (up to 16 weeks after first dose)The Subject Satisfaction with Appearance Rating Scale assesses participants' satisfaction with their appearance in association with the face and chin on a 7-point scale from 0 to 6 where 0 = Extremely dissatisfied, 1 = Dissatisfied, 2 = Slightly dissatisfied, 3 = Neither satisfied nor dissatisfied, 4 = Slightly satisfied, 5 = Satisfied and 6 = Extremely satisfied. A positive change from Baseline indicates improvement.

Percentage of Participants With an SMF Response

Response is defined as a participant with at least a 1-grade improvement in SMF Rating Scale score at Week 16 from Baseline. The SMF rating scale 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.

Time frame: Baseline and 4 weeks after last treatment (up to 16 weeks after first dose)

Population: Safety/mITT subset with available data

Percentage of Participants With a Response in the Subject Global Improvement Rating

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. Response is defined as any improvement, ie, a global improvement rating of 4, 5, or 6.

Visual Analogue Scale Pain Intensity Rating

Participants rated pain associated with the submental area on a 100 mm horizontal axis ranging from 0 (no pain) to 100 (most severe pain possible)

Time frame: Approximately 60 minutes after completion of each treatment session at Week 0, Week 4, Week 8 and Week 12

Population: Safety/mITT subset with available data at each time point (indicated by N)
