A Study of Universal CD19-Targeted UCAR-NK Cells Combined With HSCT for B Cell Hematologic Malignancies
B-Cell Lymphoblastic Leukemia/Lymphoma
About this trial
This is an interventional treatment trial for B-Cell Lymphoblastic Leukemia/Lymphoma focused on measuring universal CAR-NK(UCAR-NK), Hematopoietic Stem Cell Transplantation(HSCT)
