Brief Summary

This trial adopts a single-center, randomized, double-blind, placebo-controlled, dose-escalation design to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of HEC-007 Injection after single-dose administration in healthy subjects and multiple-dose administration in overweight or obese subjects.
