This trial aims to demonstrate the feasibility of this approach to reliably generate product and to safely administer the product to patients who have B-Cell Lymphoma and B-Acute Lymphoblastic Leukemia.

On this study the following procedures are sequentially performed: eligibility determination and informed consent; cell collection by apheresis; CAR T-cell manufacturing and lymphodepleting chemotherapy all followed by CAR T-cell infusion on day 0. The first 3 subjects will be followed in hospital from day 0 until +14 for CRS, ICANS and other toxicity. The PI and two physicians not affiliated with the study (Nathan Bahary, MD, PhD and Gene Finley, MD) will review the outcome of the first three patients to assure the interim analysis meets criteria for continuing accrual. This analysis will be submitted to the IRB prior to continuing with accrual. The toxicity profile of the first three subjects will be scrutinized. Should toxicity be minimal with CRS ≤ 2 and ICANS grade ≤1 then the PI might propose modification to hospitalization between days 0 and +14 according to comparison with prior experience with commercially available product. A protocol amendment would be submitted in this case. Should no CAR T-cell related toxicity be identified on day +15, the subject will be discharged from the hospital and followed in the Medical Short Stay Unit (or designated substitute inpatient unit) daily to day 30. At the discretion of the Investigator (based upon each subject's medical condition or status), this follow-up could be reduced to thrice weekly basis (e.g. Monday-Wednesday-Friday). CAR T-cell monitoring by flow cytometry will occur on day +30 and day +100. Response will be assessed at day +30 and the subject will be discharged for outpatient follow up. Response will be assessed monthly by clinical examination to day +100 and then every 3 months to day +730. Thereafter, clinical follow up will occur every 6 months to five years and then yearly up to 15 years, or until death (whichever occurs first). All subjects treated on this study must consent to reporting of de-identified data to the Center for International Blood and Marrow Transplantation Research (CIBMTR). (See Table 1: Schedule of Study Procedures, Figure 1: Study Diagram, Table 2: Laboratory Investigation and Table 3: Response Evaluation for details of study conduct.) The clinical care of subjects enrolled on this study is entirely within the standard of care employed for patients who receive commercial product. There are no drugs, surgical procedures, radiological investigations, laboratory tests or examinations that are considered experimental except for a peripheral blood sample to detect CAR T-cells (by flow cytometry) and the actual production/manufacture of CAR T-cells occurring in the local Cell Processing Laboratory.

For this reason, the intent of this protocol is to ensure that the standard of care is strictly followed as outlined in the SOP documents, screenshots and documents included in the appendix of this document. Thus, patients receiving commercial product and those treated on this protocol should receive the same supportive care. In addition to immune effector cells, these documents often describe methods and cellular therapy products not relevant to this investigation and for our purpose these sections can be ignored.

Inclusion Criteria:

1. Subjects with CD19+ B-cell lymphoma or B-Cell Acute Lymphoblastic Leukemia (B-ALL) with no currently available curative treatment option (such as autologous or allogeneic Hematopoietic stem cell transplantation (HSCT)) who have a limited prognosis (<2-year projected survival) will be enrolled. Participation on this trial is permitted as a bridge to HSCT.
2. Peripheral blood CD3 count > 200/µL by flow cytometry. Please note that this test might need to be repeated multiple times as standard practice to optimize collection efficiency.
3. Subjects will have a diagnosis of Diffuse Large B Cell Lymphoma (DLBCL), Follicular Lymphoma (FL), Mantle Cell Lymphoma (MCL), CLL, Marginal Zone Lymphoma (MZL), Lymphoplasmacytic Lymphoma (LPL) or B-ALL and will have failed at least 2 lines of therapy in the case of lymphoma and one line if the diagnosis is B-ALL or be refractory (no response or progressive disease) to first line therapy. A line of therapy must include conventional (immuno) chemotherapy (e.g. rituximab, cyclophosphamide, doxorubicin, and prednisone (R-CHOP) or Bendamustine plus Rituximab (BR) in the case of lymphoma) administered for at least 2 cycles. Second or greater lines of therapy must be administered for at least two cycles. Single agent anti-CD20 monoclonal antibody (e.g. rituximab, obinutuzumab) is not considered for the purposes of these criteria to count as a line of therapy. The definition of a line of therapy is taken according to recommended regimens for first and second line therapy in the relevant sections of the National Comprehensive Cancer Network (NCCN) guidelines. The most recent version of the guidelines will be used for eligibility determination. In the unlikely event that a subject received a first or second line regimen no longer listed in the most recent guidelines, but previously present in the version of the guidelines active at the time the therapy was administered, then the subject would be deemed to have received a line of therapy.
4. Subjects with pathological and clinical evidence of transformed indolent lymphoma (FL, CLL, MZL or LPL) are eligible for participation on this trial if they have received at least one line of therapy for transformed disease for at least two cycles regardless of response.
5. Demonstration of CD19 expression by immunohistochemistry or flow cytometry on a pathological specimen of lymphoma or ALL cells at any time in the course of prior treatment.
6. Subjects who are unable to receive commercially available CD19-CAR T-cell therapy.
7. Patients with lymphoma must have measurable or assessable disease. Patients in complete remission with no evidence of disease are not eligible.
8. Patients with B-ALL must have at least measurable detectable disease on two separate occasions at least 2 weeks apart to be eligible.
9. Subjects who relapse at > 100 days after autologous or allogeneic HSCT are eligible for participation on this trial. Allogeneic HSCT recipients must be off all immunosuppression for a minimum of 4 weeks before leukapheresis is performed and be free of active acute and chronic Graft Versus Host Disease (GVHD).
10. Subjects will be ≥ 18 and < 80 years of age.
11. Female subjects of childbearing potential must have a negative urine or serum pregnancy test and if sexually active must use an acceptable method of contraception, including abstinence, a barrier method (diaphragm or condom), Depo-Provera, or an oral contraceptive. Active contraception should continue for at least one year after CAR T-cell infusion.
12. Male participants must be willing to practice birth control from the time of enrollment on this study and for 6 months after receiving the preparative regimen.
