6. Coagulation function test requirements: international normalized ratio (INR) ≤ 2.0; prothrombin time (PT) ≤ 1.5 × ULN.
7. Women of childbearing potential must have a negative pregnancy test result, and be willing to take effective contraceptive measures during the trial period and for ≥ 12 months after the last dose; all male subjects must take contraceptive measures during the trial period and for ≥ 6 months after the last dose.
