E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
1. Determine the safety , survival and feasibility of administration of chimeric antigen receptor T cells transduced with the anti-CD19 lentiviral vector (referred to as “CART-19” cells), in pediatric and adult patients who either:
a. have not received a prior allogeneic SCT or have 0% residual donor engraftment (“no allo” cohort), or
b. have relapsed after prior allogeneic SCT with any degree of residual donor engraftment (“allo” cohort).
2. Determine duration of in vivo survival of CART-19 cells. 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. |
|
E.2.2 | Secondary objectives of the trial |
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-zeta only transgene as measured by the relative engraftment levels of CART-19 TCR-zeta :4-1BB and TCR-zeta cells over time.
3. For patients with stored or accessible tumor cells (such as patients with active CLL, 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)
6. Determine safety and efficacy in a test cohort of patients with CNS3 disease. |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Eligible diseases: CD19+ leukemia or lymphoma
a. ALL without curative options for therapy, including those not eligible for allogeneic SCT because of: age, comorbid disease, other contraindications to TBI-based conditioning (required for ALL SCT), lack of suitable donor, prior SCT, Declines allo SCT (in CR3) as a therapeutic option after documented discussion about the role of SCT with a BMT physician not part of the study team (see note below).

-Beyond 1st CR with relapsed or persistent disease and not eligible or appropriate for conventional allogeneic or autologous SCT.
-Disease responding or stable after most recent therapy (chemotherapy, MoAb).
-Relapsed after prior autologous SCT.
e. B-cell prolymphocytic leukemia (PLL) with relapsed or residual disease after at least 1 prior therapy and not eligible for allogeneic SCT.
f. Diffuse large cell lymphoma or other high-grade NHL, previously identified as CD19+
-Residual disease after primary therapy and not eligible for autologous SCT.
-Relapsed after prior autologous SCT.
-Beyond 1st CR with relapsed or persistent disease and not eligible or appropriate for conventional allogeneic or autologous SCT.
2. Age 1 to 24 years. Patients ages 22-24 will only be enrolled if they are currently being treated at CHOP or another pediatric facility/oncologist.
3. Expected survival > 12 weeks
4. Creatinine < 2.5 mg/dl and less than 2.5x normal for age
5. ALT <= 5x normal
6. Bilirubin <2.0 mg/dl
7. Any relapse after prior SCT will make patient eligible regardless of other prior therapy.
8. Patients with relapsed disease after prior allogeneic SCT (myeloablative or non-myeloablative) will be eligible if they meet all other inclusion criteria and
a. Have no active GVHD and require no immunosuppression
b. Are more than 4 months from transplant (6 months at infusion)
9. For those patients who require leukapheresis for T cell collection (i.e. no previously collected product exists), adequate venous access for apheresis or eligible for appropriate catheter placement, and no other contraindications for leukapheresis.
10. Voluntary informed consent is given.
11. Patients with CNS3 disease will be eligible if CNS disease is responsive to therapy |
|
E.4 | Principal exclusion criteria |
- Pregnant or lactating women. Female study participants of reproductive potential must have a negative serum or urine pregnancy test performed within 48 hours before infusion.
- Uncontrolled active infection.
- Active hepatitis B or hepatitis C infection.
- Concurrent use of systemic steroids at the time of cell infusion or cell collection, or a condition, in the treating physician's opinion, that is likely to require steroid therapy during collection or after infusion. Steroids for disease treatment at times other than cell collection or at the time of infusion are permitted. Use of inhaled steroids, or hydrocortisone for physiological replacement in patients with adrenal insufficiency are permitted as well.
- Previous treatment with any gene therapy products.
- Any uncontrolled active medical disorder that would preclude participation as outlined.
- HIV infection.
- CNS3 disease that is progressive on therapy, or with CNS parenchymal lesions that might increase the risk of CNS toxicity
- Acute or chronic GVHD requiring systemic therapy (topical allowed). |
