• Has adequate organ and bone marrow function, laboratory test values within 7 days prior to enrollment meet the following requirements (no blood components, cell growth factors, albumin, or other corrective drugs are allowed within 14 days prior to laboratory test), as follows: 1) Blood routine: absolute neutrophil count≥1.5×109/L; platelet count≥75×109/L; hemoglobin conten≥9.0 g/dL. 2) Liver function: serum total bilirubin≤2× upper limit of normal value (ULN); alanine aminotransferase and aspartate transferas≤5×ULN; Serum albumin ≥28 g/L; alkaline phosphatase≤5×ULN. 3) Renal function: serum creatinine≤1.5×ULN or clearance of creatinine≥50mL/min(Cockcroft-Gault formula); Urine routine results showed that urine protein <2+; For patients with urine protein ≥2+ on routine urine tests at baseline, 24-hour urine collection and 24-hour protein quantification <1g should be performed.
