Current Trends in Management of Submental Liposis: A Pooled Analysis and Survey
Abstract
IMPORTANCE: Since its approval by the US Food and Drug Administration for treatment of moderate to severe submental liposis in April 2015, deoxycholic acid (Kybella) has received significant media attention as a novel aesthetic treatment. Four phase 3 clinical trials have published data demonstrating the safety and efficacy of the drug compared with placebo; however, no study has juxtaposed the product with submental liposuction.
OBJECTIVE: To evaluate the efficacy of injectable deoxycholic acid in the treatment of isolated submental liposis.
EVIDENCE REVIEW: A pooled analysis of the data from the 2 European and 2 North American phase 3 clinical trials was performed by grouping the study participants by treatment arm to analyze efficacy, adverse effects, and treatment variables. Members of the American Academy of Facial Plastic and Reconstructive Surgery (AAFPRS) were also surveyed regarding their clinical use of deoxycholic acid, fees, and adverse events.
FINDINGS: The pooled analysis included 1738 unique patients (348 men [20.0%] and 1390 women [80.0%]; mean [SD] age, 47.7 [1.6] years) and revealed that all studies demonstrated efficacy compared with placebo. However, a significant number of patients experienced pain, edema, and numbness after injection. The clinical trial population was injected with a mean (SD) of 186.0 (106.6) mg of drug per patient during the course of treatment. A total of 102 members responded to the survey, representing 4% of AAFPRS membership.…
How strong is the evidence?
Evidence Hub reads this as a secondary / pooled analysis, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 1,738 participants or records.
