Upper limit of normal values (ULN) ≤2.5 times of alanine Aminotransferase (ALT) and aspartate Aminotransferase (AST) Note: ≤1.5× ULN (This criterion only applies to patients who have not received anticoagulant therapy; Patients receiving anticoagulant therapy should keep anticoagulants within therapeutic limits);
- Kidney function:
- The Cockcroft-Gault formula was used to determine the creatinine clearance (CrCl) \> 30 mL/min.
- Subjects (or their legal representatives) must sign an informed consent form (ICF) indicating that they understand the purpose and procedures of the study and are willing to participate in the study; Fertile women must have a negative pregnancy test result (beta-hCG) (urine or serum) within 7 days before the study drug is first administered.
