Brief Summary

Patients 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"). Their Lymphoma or Leukemia has come back or has not gone away after treatment (including the best treatment known for these cancers). This research study is a gene transfer study using special immune cells.

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. Antibodies are types of proteins that protect the body from bacterial and other diseases. T cells, also called T lymphocytes, are special infection-fighting blood cells that can kill other cells including tumor cells. Both antibodies and T cells have been used to treat patients with cancers; they have shown promise, but have not been strong enough to cure most patients.

T lymphocytes can kill tumor cells but there normally 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 cancer 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, investigators have also found that T cells work better if they also put a protein that stimulates T cells called CD28. Investigators hope that adding the CD28 might also make the cells last for a longer time in the body.

These CD19 chimeric receptor T cells with C28 T cells are investigational products not approved by the Food and Drug Administration.

The purpose of this study is to find the biggest dose of chimeric T cells that is safe, to see how the T cell with this 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.

Detailed Description

Patients will give us blood to make CD19 CD28 chimeric receptor-T cells in the laboratory. These cells will be grown and frozen for the patient. To make the T cells investigators take the blood and stimulate it with growth factors to make the T cells grow. To get the CD19 antibody (with CD28) to attach to the surface of the T cell, they insert the antibody gene into the T cell. This is done with a virus called a retrovirus that has been made for this study and will carry the antibody gene into the T cell. This virus also helps us find the T cells in the blood after they inject them using a special laboratory test. Because the patients will receive cells with a new gene in them they will be followed for a total of 15 years to see if there are any long term side effects of gene transfer. If the patient cannot visit the clinic, they may be contacted by the research coordinator or physician.

When the patients enroll on this study, they will be assigned a dose of CD19 CD28 chimeric receptor-T cells.

For those with intermediate or low grade lymphoma/leukemia: The investigators' studies so far have shown that the infused T cells may need to receive an extra boost in order to expand efficiently in the body. Therefore, 2 weeks after T cell infusion, the patient may receive one injection of a drug called ipilimumab, which they believe will help the T cells grow. This drug is approved by the FDA to treat certain cancers, such as melanoma, but the dose of drug used for this study will be lower than those used in those other treatments to avoid side effects.

Patients will be given an injection of cells into the vein through an IV at the assigned dose. The injection will take about 10 minutes. Patients will be followed in the clinic after the injection for up to 3 hours. If after a 4-6 week evaluation period after the infusion, the patient seems to be experiencing a benefit (confirmed by radiological studies, physical exam and/or symptoms), they may be able to receive up to three additional doses of the T cells if they wish. These additional infusions would be at least 4-6 weeks apart and at the same dose level they received the first time or a lower dose. The treatment will be given by the Center for Cell and Gene Therapy at Texas Children's Hospital or Houston Methodist Hospital.

To learn more about the way the CD19 CD28 chimeric receptor-T cells are working and how long they last in the body, extra blood will be drawn.
