YD-0293

This study is a single-center, single- and multiple-dose escalating study with a food-effect component, designed to evaluate the safety, tolerability, and pharmacokinetic (PK) characteristics of YD0293 tablets following a single oral dose in healthy subjects, as well as the effect of food on PK parameters and the potential effect on the QT interval. The study also aims to assess the safety, tolerability, and PK profile of YD0293 tablets following multiple oral doses in healthy subjects.
