Brief summary

This study is to evaluate the efficacy, edema and pain associated with Kybella(TM) injections of the upper neck in the treatment of submental fat with varying low concentrations of triamcinolone acetonide plus low doses of lidocaine.

Detailed description

This is a two-site randomized, double-blind comparison trial of Kybella(TM) injections with or without triamcinolone acetate for the reduction of submental fat. 30 subjects will be enrolled into the trial (15 subjects per site). At each site, 5 will be randomized to receive Kybella(TM) injections alone whereas 10 will receive Kybella(TM) plus differing doses of triamcinolone acetate in the following way: 1. Group 1 (5 patients per site): Kybella(TM) alone: 2 mg/cm2 of Kybella(TM) with 0.2 mL of 1% lidocaine with no epinephrine plus 0.2cc saline to the non-TMC group to maintain equal concentrations in each injection so that the final Kybella concentration per vial will be 10mg/1.2mls or 1.6mg per 0.2 cc injection point will be delivered in up to 50 injections spaced 1.0 cm apart at 0.2 mL/injection for a total maximal dose of up to 100 mg of SDOC. 2. Group 2 (10 patients per site): Kybella(TM)+TMC at 1.0 mg/mL: 2.0 mL of 2 mg/cm2 of Kybella(TM) will be mixed with 0.2 mL of 10 mg/mL of triamcinolone acetate, 0.2 mL of 1% lidocaine with no epinephrine and then delivered in up to 50 injections spaced 1.0 cm apart at 0.2 mL/injection for a total dose of up to 100 mg of SDOC using a 30 gauge (or smaller) 0.5-inch needle. The final Kybella concentration per vial will be 10mg/1.2mls or 1.6mg per 0.2 cc injection point The treatment area will be bounded superiorly by a line 1 cm inferior to the mandibular margin, laterally by the sternocleidomastoid muscles, and inferiorly by the hyoid bone. The subjects and evaluating investigator will be blinded to the treatment, thus maintaining double-blind status. By nature of the varying volumes of injection, the treating investigator will be unblinded to the treatment. A series of 3 injection sessions will be performed spaced 4 weeks apart. No lidocaine will be injected prior to injections to prevent further dilution of injected Kybella™ as it will be premixed with Kybella™. Chilling with cold will be the method of pain reduction for needle insertion. Canfield Vectra 3D imaging will be performed at baseline and final visit (Appendix C) with analysis and calculation of volumetric changes performed at baseline and final visit. Photos will also be taken with the Intellistudio at all other visits. Follow up visits will be performed 3 and 5 days after each injection session to assess for side effect and tolerability profile. After the final injection session, additional follow up visits will be performed at days 90 and 180 to assess for efficacy. Subject weight will be recorded at baseline and at end of study.

Interventions

DRUGInjectable sodium deoxycholate

Kybella(TM) alone: 2 mg/cm2 of Kybella(TM) with 0.2 mL of 1% lidocaine with no epinephrine plus 0.2cc saline to the non-TMC group to maintain equal concentrations in each injection so that the final Kybella concentration per vial will be 10mg/1.2mls or 1.6mg per 0.2 cc injection point will be delivered in up to 50 injections spaced 1.0 cm apart at 0.2 mL/injection for a total maximal dose of up to 100 mg of SDOC.

COMBINATION_PRODUCTInjectable sodium deoxycholate with Triamcinolone acetate

Kybella(TM)+TMC at 1.0 mg/mL: 2.0 mL of 2 mg/cm2 of Kybella(TM) will be mixed with 0.2 mL of 10 mg/mL of triamcinolone acetate, 0.2 mL of 1% lidocaine with no epinephrine and then delivered in up to 50 injections spaced 1.0 cm apart at 0.2 mL/injection for a total dose of up to 100 mg of SDOC using a 30 gauge (or smaller) 0.5-inch needle. The final Kybella concentration per vial will be 10mg/1.2mls or 1.6mg per 0.2 cc injection point
