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

Study Overview
=================
Brief Summary
-----------------
The primary objective is to evaluate pharmacokinetics of Fluzoparib and its main metabolite in subjects with impaired kidney function in comparison with healthy subjects, to develop dose recommendations for patients with renal impairment. The secondary objective is to evaluate the safety of Fluzoparib in subjects with mild and moderate renal impairment and in healthy subjects.
