Conditions: Moderate or Severe Submental Fullness
Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 84
Healthy volunteers: no

Brief summary:
The objectives of this study are to determine the safety of deoxycholic acid subcutaneous (SC) injections in the submental area and to evaluate the effects of four interventions, relative to placebo in the submental area, particularly with regard to assessment and management of pain, bruising, and swelling/edema.

Detailed description:
This study evaluated the effects of four interventions, pre- and post-subcutaneous injections of deoxycholic acid injection relative to placebo in adults with submental fullness. Participants were randomized to either deoxycholic acid injection or placebo in a ratio of 4:1 and to one of four patient experience management paradigms.

Participants were required to visit the research facility on 10 separate occasions for protocol-defined treatments, procedures, tests, and observations.

Arms:
arm 1: Participants received deoxycholic acid 2 mg/cm² administered in 0.2 mL injections, either 6 or 8 mL (based on Baseline CR-SMFRS grade 2 or 3, respectively) on Day 0 and a cold compress applied to the treatment area. arm 2: Participants received placebo administered in 0.2 mL injections, either 6 or 8 mL on Day 0 and a cold compress applied to the treatment area. arm 3: Participants received deoxycholic acid 2 mg/cm² administered in 0.2 mL injections, either 6 or 8 mL on Day 0, topical and injectable anesthetics (lidocaine/epinephrine) and a cold compress applied to the treatment area. arm 4: Participants received placebo administered in 0.2 mL injections, either 6 or 8 mL on Day 0, topical and injectable anesthetics and a cold compress applied to the treatment area. arm 5: Participants received deoxycholic acid 2 mg/cm² administered in 0.2 mL injections, either 6 or 8 mL on Day 0, oral antihistamine and anti-inflammatory agents (loratadine and ibuprofen), topical and injectable anesthetics and a cold compress applied to the treatment area. arm 6: Participants received placebo administered in 0.2 mL injections, either 6 or 8 mL on Day 0, oral antihistamine and anti-inflammatory agents, topical and injectable anesthetics and a cold compress applied to the treatment area. arm 7: Participants received deoxycholic acid 2 mg/cm² administered in 0.2 mL injections, either 6 or 8 mL on Day 0, a compression chin strap, oral antihistamine and anti-inflammatory agents, topical and injectable anesthetics and a cold compress applied to the treatment area. arm 8: Participants received placebo administered in 0.2 mL injections, either 6 or 8 mL on Day 0, a compression chin strap, oral antihistamine and anti-inflammatory agents, topical and injectable anesthetics and a cold compress applied to the treatment area.

Interventions: intervention 1: Deoxycholic Acid Injection intervention 2: Placebo intervention 3: Cold Compress intervention 4: Lidocaine / Epinephrine intervention 5: Loratadine intervention 6: Ibuprofen intervention 7: Compression Chin Strap
Intervention descriptions: intervention 1: Formulated as an injectable solution containing deoxycholic acid at a concentration of 10 mg/mL. intervention 2: Phosphate buffered saline placebo for injection intervention 3: A cold compress was applied to the injection area for 10 minutes before dosing and for 15 minutes after dosing. intervention 4: Lidocaine 4% topical cream applied 45 minutes prior to dosing across the area to be treated, followed by 0.4 mL SC injections of lidocaine HCl 1% / epinephrine 1:100,000 around the perimeter of the treatment area and across the treatment area in a regular pattern 25 minutes before dosing. intervention 5: Loratadine 10 mg orally from Day -7 until Day 7 intervention 6: Ibuprofen 600 mg at least 1 hour prior to dosing and 600 mg 3 times a day for at least 3 days after dosing. intervention 7: A compression chin strap was applied 15 minutes after dosing for at least 24 hours.
