Brief Summary:

This is a study for children who have been previously treated for Leukemia/Lymphoma. In particular, it is a study for people who have a type of Leukemia/Lymphoma that involves B cells (a type of white cell), which contain the cancer. This is a new approach for treatment of Leukemia/Lymphoma that involves B cells (tumor cells). This study will take the subject's white blood cells (T cells) and modify them in order to target the cancer.

The subject's T cells will be modified in one or two different ways that will allow the cells to identify and kill the tumor cells (B cells). Both ways of modifying the cells tells the T cells to go to the B cells (tumor cells) and turn "on" and potentially kill the B cells (tumor cells). The modification is a genetic change to the T cells, or gene transfer, in order to allow the modified T cells to recognize your tumor cells but not other normal cells in the subject's body. These modified cells are called chimeric antigen receptor 19 (CART19) T-cells.

Condition or disease	Intervention/treatment	Phase
B Cell Leukemia; B Cell Lymphoma	Biological: CART-19	Phase 1

Detailed Description:

At entry subjects will be staged and the suitability of their T cells for CART-19 manufacturing will be determined. Subjects who have adequate T cells will be leukapheresed to obtain large numbers of peripheral blood mononuclear cells (PBMC) for CART-19 manufacturing. The T cells will be purified from the PBMC, transduced with CART-19 lentiviral vector, expanded in vitro and then frozen for future administration. Chemotherapy will then be given. Following tumor burden reassessment, CART-19 cells will be thawed and infused.

Subjects will have blood tests to assess safety, and engraftment and persistence of the CART-19 cells at regular intervals through four weeks after their last infusion of the study. Following the 6 months of intensive follow-up, subjects will be evaluated quarterly for two years with a medical history, a physical examination, and blood tests. Following this evaluation, subjects will enter a roll-over study for annual follow-up by phone and questionnaire for an additional thirteen years to assess for the diagnosis of long-term health problems, such as development of new malignancy.

Primary objectives:

1. Determine the safety and feasibility of administration of chimeric antigen receptor T cells transduced with the anti-CD 19 lentiviral vector (referred to as "CART-19" cells).
2. Determine duration of in vivio survival of CART-19 cells. Real Time polymerase chain receptor (RT-PCR) analysis of whole blood will be used to detect and quantify survival of CART-19 TCR:4-1BB and TCR cells over time.

Secondary objectives:

1. For patients with detectable disease, measure anti-tumor response due to CART-19 cell infusions.
2. To determine if the 4-1BB transgene is superior to the TCR only transgene as measured by the relative engraftment levels of CART-19 TCR:4-1BB and TCR cells over time.
3. For patients with stored or accessible tumor cells (such as patients with active chronic lymphocytic leukemia (CLL), acute lymphoblastic leukema (ALL), etc) determine tumor cell killing by CART-19 cells in vitro.
4. Determine if cellular or humoral host immunity develops against the murine anti-CD19, and assess correlation with loss of detectable CART-19 (loss of engraftment).
5. Determine the relative subsets of CART-19 T cells (Tcm, Tem, and Treg)

Arm	Intervention/treatment
Experimental: CART-19 T Cells; The subject's thawed T cells will be modified in one or two different ways that will allow the cells to identify and kill the tumor cells (B cells). The T cells will be infused over 10-15 minutes on days Days 0, and 1. Day 14 is tentative based on response.

Primary Outcome Measures :

1. Number of Participants with Severe/Adverse Events as a Measure of Safety and Tolerability [ Time Frame: 24 weeks ]
   Safety of CAR+ T cell infusion and observed side effects

Secondary Outcome Measures :

1. Ability of two different types of CAR+ T cells to expand and persist in the patient [ Time Frame: 24 weeks ]
   The change in the ratio of the vector transduced cells to each other between baseline and week four will be evaluated. Observation and monitoring of patients will continue on a monthly basis until week 24 post dosing
2. Impact of CAR+ T cell infusion on cancer [ Time Frame: 4 weeks ]
   Patients with measurable disease will be assessed for the response of their disease to the CAR+ T cell treatment

Criteria

Inclusion Criteria:

Male and female subjects with CD 19+ B cell malignancies in patients with no available curative treatment options (such as autologous or allogeneic SCT) who have limited prognosis (several months to <2 year survival) with currently available therapies will be enrolled:

1. Eligible diseases: CD 19+ leukemia or lymphoma

   1. ALL without curative options for therapy, including those not eligible for allogeneic

      SCT because of:
