AYP-101 is a newly developed injectable agent containing 93% soybean phosphatidylcholine (SPC) designed to reduce submental fat. We conducted a phase 1 study to evaluate the safety, pharmacokinetic (PK), and lipid profile effects of AYP-101.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This study was a randomized, double-blind, placebo-controlled, single-dose, two-cohort trial. Participants were randomized into groups receiving 250\u00a0mg of AYP-101, 500\u00a0mg of AYP-101, or placebo at a 9:9:8 ratio across both cohorts. Safety was assessed through standard clinical evaluations. Blood samples were collected up to 144\u00a0h postdose in cohort 1 and up to 48\u00a0h postdose in cohort 2.

A total of 72 solicited adverse drug reactions (ADRs) were reported by 24 subjects, all of which were mild. The most common ADRs were injection site pain and bruising. There were 29 ADR cases in the 250\u00a0mg group; 26 cases in the 500\u00a0mg group; and 18 cases in the placebo group, indicating that there were no clinically significant differences in the safety profiles between the groups.
