  4. Subjects with medically stable RI until study completion corresponding to the classifications of Renal Function based on GFR: mild RI: 60≤GFR<90 mL/min; moderate RI: 30≤GFR<60 mL/min, severe RI:15≤GFR<30 mL/min;
  5. Physical examination, vital sign measurements, 12-lead electrocardiogram (ECG), and clinical laboratory tests results were deemed appropriate by the investigator;
  6. Not in use of any drug within 2 weeks prior to screening, except for the medication necessary for RI/ other comorbidities (last more than four weeks in good compliance);

  3. Male subjects weight ≥50 kg and female subjects weight ≥45 kg, weight must be matched with subjects with RI. Body mass index (BMI) : 18-30 kg/m^2 (inclusive) (BMI= weight (kg)/height2 (m^2));
  4. 90≤GFR<130 mL/min;
  5. Physical examination, vital sign measurements, 12-lead electrocardiogram (ECG), and clinical laboratory tests results were deemed appropriate by the investigator;
  6. Not in use of any drug within 2 weeks prior to screening, except for the medication necessary for comorbidities (last more than four weeks in good compliance);
  7. Subjects (including partners) are willing to voluntarily use effective contraceptives from screening to at least 6 months after the last dose administration.
