Brief Summary

The Primary objectives of this study are to evaluate the safety and tolerability of ZSP1603 and the Secondary objective is to estimate the pharmacokinetic (PK) parameters after orally administered once daily of ZSP1603.

Detailed Description

This is a Phase 1, double-blinded, placebo-controlled, single center study aimed at investigating the safety, tolerability and the pharmacokinetics of ZSP1603 on fasted condition.Up to 4 cohorts of 32 eligible participants totally are planned to be enrolled. This is a two-arm clinical trial that ZSP1603 and matching placebo will be orally administered once daily. Two subjects in the first cohort will be assigned in a opened fashion to receive 7.5mg of ZSP1603 while another three cohorts of volunteers will be randomly assigned in a blinded fashion to receive either a single dose of ZSP1603 or matching placebo in an ascending dose fashion. To monitor AEs,record abnormalities (Holter, 12-lead ECG, Vital signs, Physical examination, Clinical Laboratory), and detect the pharmacokinetics of ZSP1603.
