A Phase 1 Study of FXR0906 in Healthy Adults With or Without Elevated Triglycerides

This is a phase 1, randomized, double-blind, placebo-controlled study to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics effects of a single dose of FXR0906 injection or placebo in Chinese healthy adult volunteers with or without TG increase.

Inclusion criteria： 1\. Males or females aged ≥18 and ≤55 years at the time of screening; 2. Body mass index (BMI) ≥18.0 and ≤35.0 kg/m² at the time of screening, with female participants weighing \>45 kg and male participants weighing \>50 kg; 3.
