Pharmacokinetics of Chiglitazar in Subjects With Hepatic Impairment and Normal Hepatic Function

This Phase 1 open label study is being conducted to directly characterize the pharmacokinetic (PK) profiles of Chiglitazar following administration of a single oral dose in subjects with varying degrees of hepatic impairment compared to subjects with normal hepatic function.

Supplementary exclusion criteria for subjects with hepatic impairment：

* drug-induced liver injury.
* acute liver function damage caused by various reasons;
* complications of liver cirrhosis that the investigator considers inappropriate to participate in the study.
* diseases that seriously affect bile excretion.

Supplementary exclusion criteria for subjects with normal hepatic function:

* history of hepatic function damage, or who may have hepatic function damage that the investigator considers to be clinically significant.
* positive test for HBsAg, HCV.
