Overview
This is a study to evaluate the safety, tolerability, pharmacokinetics, and food effects of SHEN211 tablet in healthy subjects after fasting single or multiple oral administration
Description
The whole trial consisted of three parts: Part 1 was a single-center, randomized, double-blind, placebo-controlled, single-dose dose increasing safety, tolerability and pharmacokinetic test; Part 2 was a single-center, randomized, double-blind, placebo-controlled, multiple-dose safety, tolerability and pharmacokinetic study. Part 3 is a single-dose, randomized, open, two-phase, double-cross, two-sequence design trial of the effects of food on the main PK parameters of SHEN211 tablets in healthy subjects.
