NCT03599375

Brief Summary

This study aims to evaluate the safety and clinical activity of CD19 Chimeric Antigen Receptor (CAR) redirected autologous T-cells in treating patients with recurrent or refractory CD19 positive B cell ccute lymphoblastic leukemia,and dynamically observe the changes of CAR-T in patients and the residual tumor.

Outcome Measures

Primary Outcomes (1)

  • overall response rate(ORR)

    ORR is defined as the proportion of partial responses plus complete responses.

    Participants will be followed for the duration of the treatment, with an expected average of 3 months.

Secondary Outcomes (2)

  • Progression free survival(PFS)

    15 years

  • Overall survival(OS)

    15 years

Study Arms (1)

B-ALL treated with CD19 CART cell

EXPERIMENTAL

The qualified CD19-targeted CART cells will be transferred to patient for 3 days as follow:D1,10% fraction;D2,30%;D3 60%. The number of CART cells for each course will be about 1×106/kg. If complete response (CR) or complete response with incomplete hemogram recovery (CRi) in hemogram is achieved after the first course of treatment, further treatment will be decided according to the clinical assessment and the wishes of the patient.If partial response (PR) is achieved after the first course, 1 or 2 courses of treatment will be continued. If there is no response (NR) after the first course, the treatment will be ceased or restarted based on the clinical assessment or patients' wishes. Treatent may be discontinued due to any severe toxicity, such as cytokine release syndrom.

Biological: CD19-targeted CART cells

Interventions

CD19 CAR T cells was transduced with a lentiviral vector to express anti-CD19 scFv.This is a second generation CRAT.
