Who this trial is looking for
This trial is looking for patients with certain types of blood cancers like Non-Hodgkin Lymphoma, leukemia, or who have had issues with previous treatments. Participants will receive a specialized treatment using their own T-cells to help fight the cancer.

Subjects on this study have a type of lymph gland cancer called Non-Hodgkin Lymphoma, acute lymphocytic leukemia, or chronic Lymphocytic Leukemia (these diseases will be referred to as "lymphoma" or "leukemia"). The lymphoma or leukemia has come back or has not gone away after treatment.

Subjects on this study have a type of lymph gland cancer called Non-Hodgkin Lymphoma, acute lymphocytic leukemia, or chronic Lymphocytic Leukemia (these diseases will be referred to as "lymphoma" or "leukemia"). The lymphoma or leukemia has come back or has not gone away after treatment.
The body has different ways of fighting infection and disease. No one way seems perfect for fighting cancers. This research study combines two different ways of fighting disease, antibodies and T cells, hoping that they will work together. Both antibodies and T cells have been used to treat patients with cancer. They have shown promise, but have not been strong enough to cure most patients.
T cells can kill tumor cells but normally there are not enough of them to kill all the tumor cells. Some researchers have taken T cells from a person's blood, grown more of them in the laboratory and then given them back to the person.
The antibody used in this study is called anti-CD19. It first came from mice that have developed immunity to human lymphoma. This antibody sticks to lymphoma cells because of a substance on the outside of these cells called CD19. CD19 antibodies have been used to treat people with lymphoma and leukemia. For this study, anti-CD19 has been changed so that instead of floating free in the blood it is now joined to the T cells. When an antibody is joined to a T cell in this way it is called a chimeric receptor.
In the laboratory, the investigators found that T cells work better if they also add proteins that stimulate T cells, such as one called CD28. Adding the CD28 makes the cells last longer in the body but not long enough for them to be able to kill the lymphoma cells. The investigators believe that if they add an extra stimulating protein, called CD137, the cells will have a better chance of killing the lymphoma cells.
The investigators are going to see if this is true by putting the CD19 chimeric receptor with CD28 alone into half of the cells and the CD19 chimeric receptor with CD28 and CD137 into the other half of the cells. These CD19 chimeric receptor T cells with CD28 and with or without CD137 are investigational products not approved by the FDA.
The purpose of this study is to find the biggest dose of chimeric T cells that is safe, to see how long the T cell with each sort of chimeric receptor lasts, to learn what the side effects are and to see whether this therapy might help people with lymphoma or leukemia.

Inclusion Criteria:
PROCUREMENT
Referred patients (or respective donors) will initially be consented for procurement of blood for generation of the transduced ATL. Eligibility criteria at this stage include:
* Diagnosis of recurrent B-cell lymphoma or leukemia (ALL or CLL), or newly diagnosed patients unable to receive or complete standard therapy OR diagnosis of relapsed/refractory aggressive B-cell lymphoma with a treatment plan that will include high dose therapy and autologous stem cell transplantation.
* CD19-positive tumor (result can be pending at this time).
* Age \<= 75 years. The first 3 patients treated on the study should be adults (\>= 18 years).
* Hgb greater than or equal to 7.0 (can be a transfused value)
* If pheresis required to collect blood:
* Creatinine \< 1.5 x upper limit normal
* AST \<1.5 × upper limit normal
* PT and APTT \<1.5 × upper limit normal
* Informed consent explained to, understood by and signed by patient/guardian (and donor, where applicable). Patient/guardian given copy of informed consent.
TREATMENT
* Diagnosis of recurrent B-cell lymphoma leukemia (ALL or CLL), or newly diagnosed patients unable to receive or complete standard therapy OR diagnosis of relapsed/refractory aggressive B-cell lymphoma with a treatment plan that will include high dose therapy and autologous stem cell transplantation.
* CD19-positive tumor.
* Age \<= 75 years. The first 3 patients treated on the study should be adults (\>= 18 years).

Exclusion Criteria:
PROCUREMENT
* Active infection requiring antibiotics.
* No history of other cancer (except non-melanoma skin cancer or in situ breast cancer or cervix cancer) unless the tumor was successfully treated with curative intent at least 2 years before trial entry.
