a study to evaluate the pharmacokinetics of apatinib in subjects with impaired renal function

Conditions: Subjects With Impaired Renal Function and Healthy Subjects

Summary: the primary objective of the study is to compare the pharmacokinetics of apatinib in subjects with impaired renal function and healthy subjects, to give dose recommendations for patients with impaired renal function.
