Pharmacokinetic/Pharmacokinetic and Safety Studies of SHR4640 in Subjects With Moderate Renal Insufficiency and Healthy Subjects

Inclusion Criteria: - Moderate renal impaired subjects: Able and willing to provide a written informed consent. 18 years to 65 years (inclusive). Body mass index should be between 18 and 35 kg/m2 (inclusive). eGFR should be between 30 and 59 mL/min/1.73 m2 (inclusive).

If subjects with underlying diseases required drug treatment, the dose needs to be kept stable during study. Healthy subjects: Able and willing to provide a written informed consent. 18 years to 65 years (inclusive). Body mass index should be between 18 and 35 kg/m2 (inclusive). eGFR should be ≥ 90 and < 130 mL/min/1.73 m2.
