  The frequency, severity, and laboratory findings of all adverse events/serious adverse events are included. Description, time, classification, and outcome of AE events resulted from the investigational medical product, delivery method, or emergency measures will be recorded in the case report form.

  Up to 12 months after infusion

Secondary Outcomes (7)

• Granulocyte implantation time

  Up to 1 month after infusion

• Platelet implantation time

  Up to 1 month after infusion

• Red blood cell implantation time

  Up to 1 month after infusion

• Duration of remission (DOR)

  Up to 24 weeks after infusion

• Disease control rate (DCR)

  Up to 24 weeks after infusion

Study Arms (1)

Treatment group

EXPERIMENTAL

Patients will get infused with anti-CD19 CAR-NK cells within 1 week after hematopoietic stem cell infusion.

Biological: anti-CD19 UCAR-NK cells

Interventions

anti-CD19 UCAR-NK cells BIOLOGICAL

Enrolled participants are chosen to receive one of three different dose levels of U-CAR-NK cells: Dose level one: 5-10×10\^6/kg; Dose level two:1-2×10\^7/kg; Dose level three:2-5×10\^7/kg.
