Safety and Pharmacokinetics of Fluzoparib in Healthy Subjects and Those With Impaired Liver Function

This study is designed to evaluate the safety and pharmacokinetics of Fluzoparib in subjects with impaired liver function in comparison with healthy subjects ,to develop dose recommendations for patients with hepatic impairment.
