Title

CD19 CAR-T Cells for Patients With Relapse and Refractory CD19+ B-ALL.
Phase I Study of the Safety and Efficacy of CD19 CAR-T Cells in Patients With Relapsed or Refractory Acute B-cell Lymphoblastic Leukemia (R/R B-ALL)

  • Phase

    Phase 1

  • Study Type

    Interventional

  • Status

    Unknown status

  • Study Participants

    18
This is a single center, single arm, open-lable phase 1 study to determine the safety and efficacy of CD19-CAR-T cells in patients with relapsed or refractory acute B-cell lymphoblastic leukemia (R/R B-ALL).
In this single-center, open-label, nonrandomized, no control, prospective clinical trial, no less than 18 CD19+ B-cell relapsed or refractory acute B-cell lymphoblastic leukemia (R/R B-ALL) patients will be enrolled. Side effects of CD19 CAR T cells therapy will be monitored. The purpose of current study is to determine the clinical efficacy and safety of CD19 CAR T cells therapy in patients with R/R B-ALL.

Biological CD19 CAR-T cells

T cells purified from the PBMC of subjects, transduced with 4-1BB/CD3-ζ lentiviral vector, expanded in vitro for future administration.

CD19-CAR-T Cells Experimental

Subjects will receive CD19-CAR-T Cells on Day 0 : 100% of total dose.
