Outcome Measures

Primary Outcomes (1)

  • Incidence of severe CRS

    The safety of the CD19 CAR-T cells treatment will be evaluated and the maximum tolerated dose will be determined

    30 days after infusion of CD19 CAR-T cells

Secondary Outcomes (1)

  • Overall response of CD19 CAR-T cells treatment who achieve morphology complete remission(CR) and MRD negativity.

    30 days after infusion of CD19 CAR-T cells

Study Arms (2)
