The goal of this clinical trial is to learn the safety, tolerability and pharmacokinetics of single and multiple doses of HY6725 in healthy adult participants. The main questions it aims to answer are:
* How is the safety and tolerability following administration of single and multiple doses of HY6725 in healthy adult participants?
* What is the PK character of HY6725 following administration of single and multiple doses of HY6725 in healthy adult participants?
Researchers will compare HY6725 to a placebo (a look-alike substance that contains no drug) to see if HY6725 is safe and well tolerated.
Participants will take HY6725 or a placebo once or twice in single dose group or multiple dose group. And will be follow-up until Day 150.
