入选标准
- •Age: a.Dose Escalation phase: Patient aged =15 years and =70 years; b.Dose Expansion phase: Patient aged =12 and =70 years, Diagnosis and Prior Therapy: a.Dose Escalation phase: Diagnosed with R/R B-ALL; prior therapy must include at least one standard chemotherapy regimen and at least one salvage regimen. There must be no available alternative curative therapies and patients must be ineligible for allogeneic hematopoietic stem cell transplantation (HSCT), have refused HSCT, recurred after HSCT, or have active disease that prohibits HSCT at the time of enrollment. b.Dose Expansion phase: Diagnosed with R/R B-ALL; prior therapy must include at least one standard chemotherapy regimen and at least one salvage regimen, and must have included a CD19 targeted treatment. There must be no available alternative curative therapies and patients must be ineligible for allogeneic hematopoietic stem cell transplantation (HSCT), have refused HSCT, recurred after HSCT, or have active disease that prohibits HSCT at the time of enrollment, Disease burden:a.Dose Escalation phase: Patients must have measurable or evaluable disease in the bone marrow of at least 0.01% blasts or non-CNS extramedullary disease at the time of enrollment; b.Dose Expansion phase: Patients must have measurable or evaluable disease in the bone marrow of at least 5% blasts at the time of enrollment, CD22 Expression: a.Dose escalation phase: At least 70% of B-ALL blast cells expressing CD22 by flow cytometry performed as per standard practice; b.Dose expansion phase: At least 70% of B-ALL blast cells must express CD22 by flow cytometry performed as per standard practice, Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1 for subjects = 18 years; Lansky/Karnofsky score = 70 for subjects < 18 years, Adequate organ function, including renal and hepatic function based on the last assessment performed within the Screening Period, defined as: i)Creatinine clearance =60 mL/min (assessed as glomerular filtration rate using the Cockcroft-Gault formula); ii)Alanine aminotransferase and aspartate aminotransferase 3×upper limit of normal (ULN) or =5×ULN if deemed to be elevated due to leukemic involvement; iii)Total bilirubin 2×ULN or =3×ULN if deemed to be elevated due to leukemic involvement; iv)Left ventricular ejection fraction =50%, Women of childbearing potential must have a negative, highly sensitive serum pregnancy test performed within 7 days prior to enrollment
