Brief Summary

The study is a randomized, doubled-blinded, placebo-controlled, Phase I trials. The study is divided into two parts. The first part is a single-dose escalated study (SAD,part 1A ) and food effect study (SAD, part 1B ) in healthy subjects. The second part is a multi-dose escalated study (MAD) in healthy subjects.
