Humanized CD19 Chimeric Antigen Receptor (CAR)-Modified T Cell Therapy in Treating Patients With B-cell Malignancies

Study Description
Brief Summary:
This is a single arm, open-label study to evaluate the safety and efficacy of humanized anti-CD19 CAR-T cells in patients with relapsed or refractory B cell Malignancies.

Condition or disease Intervention/treatment Phase
Acute Lymphoblastic Leukemia B Cell Lymphoma Genetic: Second generation humanized CAR-T cells Phase 1

Detailed Description:
Chimeric antigen receptor (CAR)-modified T cells (CAR-T cells) have the capabilities to recognize tumor associated antigen and kill tumor cells specifically. CAR-T therapy showed great effect on patients with relapsed or refractory B cell malignancies. To improve the efficacy and safety, the researchers designed a second-generation humanized CAR, consisting of humanized CD19 single chain variable fragment (scFv) and CD137 costimulatory domain. This study aims to evaluate the safety and effectiveness of humanized anti-CD19 CAR-T cells in patients with relapsed or refractory B cell Malignancies.

Outcome Measures
Primary Outcome Measures :
  1. Number of participants with adverse events [ Time Frame: 5 years ]
    Therapy-related adverse events were recorded and assessed according to the National Cancer Institute's Common Terminology Criteria for Adverse Events (CTCAE, Version 4.0)


Secondary Outcome Measures :
  1. One-month remission rate [ Time Frame: 1 month ]
    Response of B-ALL to CAR-T therapy was assessed on day 30 (±2), against the National Comprehensive Cancer Network (NCCN, Version 1.2015).

  2. Overall survival [ Time Frame: 5 years ]
    OS was calculated from the first CAR-T cell infusion to death or last follow-up (censored).

  3. Event-free survival [ Time Frame: 5 years ]
    EFS was calculated from the first CAR-T cell infusion to death, progression of the disease, relapse or gene recurrence, whichever came first, or last visit (censored).

  4. Relapse-free survival [ Time Frame: 5 years ]
    RFS was calculated from the first CAR-T cell infusion to relapse or last visit (censored).

  5. Rate of anti-CD19 CAR-T cells in bone marrow cells and peripheral blood cells [ Time Frame: 5 years ]
    In vivo (bone marrow and peripheral blood) rate of CAR-T cells were determined by means of flow cytometry.

  6. Quantity of anti-CD19 CAR-T cells in bone marrow cells and peripheral blood cells [ Time Frame: 5 years ]
    In vivo (bone marrow and peripheral blood) quantity of CAR-T cells were determined by means of flow cytometry.

  7. Quantity of anti-CD19 CAR copies in bone marrow cells and peripheral blood cells [ Time Frame: 5 years ]
    In vivo (bone marrow and peripheral blood) quantity of anti-CD19 CAR copies were determined by means of qPCR.
