9. If the major organs are functioning normally, the following criteria are met:

   1. Blood routine examination must meet (no blood transfusion within 14 days, no hematopoietic factor and no drug correction) : ANC ≥ 1.5×10^9/L; HB ≥ 90 g/L; PLT ≥ 100×10^9/L

   3. Renal function must meet the following criteria: serum creatinine (Cr) ≤1.5×ULN, or creatinine clearance ≥40 mL/min (using the standard Cockcroft-Gault formula)
   4. Coagulation function must meet: INR≤1.5 and APTT≤1.5ULN

10. Female who are fertile must have a serum or urine pregnancy test within 72 hours before the first medication and the result is negative. Fertile female and male subjects whose partners are fertile female must agree to a highly effective method of avoiding and breastfeeding during the study period until 90 days after the last dose of the study drug. The investigator or designee, in consultation with the subject, shall confirm that the subject understands the proper and consistent use of contraceptive methods

11. For males, they should be surgically sterilized or consent to a highly effective method of avoidance during the trial and for 90 days after the last administration of the experimental drug
