Brief Summary:
This phase 1 / 2 study will evaluate the response of B-cell malignancies expressing CD19 to autologous T cells transduced with a second generation anti-CD19 chimeric antigen receptor in children and young adults.

Condition or disease Intervention/treatment Phase
Acute Lymphoblastic Leukemia, B-precursor Non-Hodgkin Lymphoma, B-cell Biological: CD19 CAR T cells Phase 1 Phase 2

Detailed Description:

Autologous T cells transduced with chimeric antigen receptors (CAR) that recognize the CD19 antigen (CD19-CAR T cells) have been used in multiple clinical trials at several institutions worldwide. We established an in-house manufacturing process for CD19-CAR T cells with a CD28 (cluster of differentiation 28) costimulatory domain.

Primary Objectives:

  1. To study the safety of administration of CAR T cell at the Sheba Medical Center
  2. To determine the feasibility and efficacy of administering anti-CD19-CAR T cells in children and young adults with B cell malignancies.

Secondary Objectives

  1. To study in vivo and in vitro behavior of CAR T cell in patients, including persistence, expansion, cytotoxic potential and exhaustion.
  2. To study the cytokine milieu in CAR treated patients.

Eligibility Patients 1-50 years of age, with a CD19-expressing B-cell malignancy that has recurred after, or not responded to, one or more standard chemotherapy-containing regimens.

Design Peripheral blood mononuclear cells (PBMCs)will be obtained by leukapheresis. Anti-CD19 CAR T cells will be manufactured from fresh autologous PBMCs. PBMC will be cultured in the presence of anti-CD3 (cluster of differentiation 3) antibody and interleukin-2 followed by retroviral vector supernatant containing the anti-CD19 CAR. Total culture time is between 7-10 days. Patients will receive lymphodepleting chemotherapy composed of cyclophosphamide and fludarabine prior to cell infusion, and on day 0 will receive one million CAR T cells per kilogram. Patients will be monitored for toxicity including cytokine release syndrome, hematologic toxicities and B-cell aplasia; for response of their underlying malignancy; and for CAR-T cell persistence in the blood, marrow and cerebral spinal fluid (CSF).

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Number of patients with treatment related adverse events as assessed by CTCAE v4. [ Time Frame: 2 years ]
  2. Overall Response Rate [ Time Frame: 28 days ]
    Overall response rate = complete response (CR) + partial response (PR) + complete response with incomplete count recovery (CRi) in leukemia patients; Assessment using bone marrow evaluation for patients with leukemia, and imaging (CT / PET CT) for patients with lymphoma

  3. Feasibility of CD19 CAR T cell production as defined by number of products successfully meeting release criteria [ Time Frame: 12 days ]
    For each participant, the feasibility of generating sufficient autologous CAR T cells within 12 days will be evaluated.


Secondary Outcome Measures :
  1. CAR T cell persistence as measured by enumeration of CAR T cells in the blood and bone marrow of participants [ Time Frame: 1 year ]
    Enumeration of CAR T cells in the blood and bone marrow of participants

  2. T cell activity and exhaustion profile as measured by flow cytometry [ Time Frame: 3 months ]
    Assessment of T cells from peripheral blood by flow cytometry for expression of activation and exhaustion markers.

  3. Cytokine levels in the peripheral blood of the patients [ Time Frame: 30 days ]
    Measurement of cytokines in the blood of participants following CAR T cell administration
