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

This phase 1 study is to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of single dose of FXR0906 injection in healthy adults with or without TG increase. Eligible enrolled participants will be randomized to 3 groups receiving FXR0906 (dose 1 or dose 2) or placebo on Day 1 and will be followed up for about 26 weeks
