Spots Global Cancer Trial Database for Activated T Lymphocytes Expressing CARs, Relapsed CD19+ Malignancies Post-Allo HSCT(CARPASCIO)

Study Description

Brief Summary: Patients have a type of lymph gland cancer called Non-Hodgkin Lymphoma (NHL), acute lymphocytic leukemia (ALL) or chronic lymphocytic leukemia (CLL) (these diseases will be referred to as "lymphoma" or "leukemia"). The lymphoma or leukemia has come back or has not gone away after treatment (including the best treatment known for these cancers). Because there is no standard treatment for this cancer at this time, subjects are asked to volunteer to be in a gene transfer research 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. 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 cells 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. 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, the CD19 antibody 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. The T lymphocytes will also contain CD28, which stimulates T cells and makes them last longer. Treatment with CD19/CD28 chimeric receptor-T cells has had activity against lymphoma and leukemia when the cells are made from the patients affected by these diseases. In this study, investigators are going to see if this treatment works even better when they make these cells from a healthy stem cell donor. If investigators are not able to collect blood from the stem cell donor, they will collect blood from the subject to make the CD19/CD28 chimeric receptor-T cells. These CD19/CD28 chimeric receptor T cells 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 T cells with this chimeric receptor last, to learn what the side effects are, and to see whether this therapy might help people with lymphoma or leukemia after a stem cell transplantation from a donor.

Detailed Description: The subject or his/her donor will give blood to make CD19/CD28 chimeric receptor-T cells in the laboratory. These cells will be grown and frozen. To make the T cells, the donor/subject's blood will be stimulated 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, an antibody gene will be inserted 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 investigators find the T cells in the blood using a special laboratory test. Subjects will be followed for a total of 15 years to see if there are any long term side effects of gene transfer. When a subject enrolls on this study, s/he will be assigned a dose of CD19/CD28 chimeric receptor-T cells and should not receive other cancer treatment until 6 weeks after cell infusion. Several studies suggest that the infused T cells need room to be able to proliferate and accomplish their functions and that this may not happen if there are too many other T cells in circulation. Because of that, if the subject's level of circulating T cells is relatively high, s/hemay receive treatment with cyclophosphamide (Cytoxan) and fludarabine (chemotherapy drugs) before the T cells. If the subject is already receiving chemotherapy, this may not be needed. The subject will be given an injection of cells into the vein through an IV at the assigned dose. The injection will take up to 10 minutes. The research staff will follow the subject in the clinic after the injection for up to 4 hours. If after a 4-6 week evaluation period after the infusion, the subject seems to be experiencing a benefit (confirmed by radiological studies, physical exam and/or symptoms), s/he may be able to receive up to 5 additional doses of the T cells. These additional infusions would be at least 4-6 weeks apart and at the same dose level received the first time or a lower dose. There will be medical tests during and after treatment. To learn more about the way the CD19 chimeric receptor-T cells are working and how long they last in the body, extra blood will be drawn.
