A Study to Evaluate the Pharmacokinetics of HSK16149 in Subjects With Renal Impairment

This is an open-label, single-dose study to evaluate the pharmacokinetics and safety of HSK16149 in subjects with mild, moderate and severe renal impairment compared to the matched control subjects with normal renal function.

  2. 18 years to 75 years (inclusive), male and female;
  3. Male subjects weight ≥50 kg and female subjects weight ≥45 kg. Body mass index (BMI) : 18-30 kg/m2 (inclusive) (BMI= weight (kg)/height2 (m\^2));
  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;
