Brief Summary
Patients have high-risk neuroblastoma, a form of cancer typically found in children. The patients previously participated in a gene transfer research study using special immune cells. This research study combines two different ways of fighting disease, antibodies and T cells. Antibodies are types of proteins that protect the body from bacterial and other infections. T cells, also called cytotoxic T lymphocytes or CTLs, are special infection-fighting blood cells that can kill some tumor cells. Both antibodies and T cells have been used to treat patients with cancers and while they have shown promise, they have not been strong enough to cure most patients. The antibody used in this study is called 14g2a. This antibody sticks to neuroblastoma cells because of a substance on the outside of these cells called GD2. 14g2a and other antibodies that bind to GD2 have been used to treat people with neuroblastoma. For this study 14g2a has been changed so that instead of floating free in the blood, it is now joined to T cells. When an antibody is joined to a T cell in this way it is called a chimeric receptor. T lymphocytes or CTLs can kill tumor cells but there normally are not enough of them to kill all 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 patient. Sometimes an antibody or chimeric receptor is attached to these T cells to help them bind to tumor cells. These chimeric receptor-T cells seem to kill some of the tumor, but they don't last very long in the body and so the tumor eventually comes back. We have found that T cells that are also trained to recognize the virus that causes infectious mononucleosis, Epstein Barr Virus (EBV), can stay in the blood stream for many years. By joining the 14g2a antibody to the CTLs that recognize EBV, we believe we will make a cell that can last a long time in the body (because they are EBV-specific) and recognize and kill neuroblastoma cells (because an antibody that can recognize these cells has been placed on their surface). Patients received treatment with the immune cells described above. They may want to receive an additional dose of these cells. This is being offered as an option because their neuroblastoma has returned and they have enough cells remaining to provide the patients with an additional dose. These 14g2a antibody CTLs are an investigational product not approved by the Food and Drug Administration.

Outcome Measures
Primary Outcomes (1)
Evaluate the safety of escalating doses of 14g2a.zeta chimeric receptor transduced autologous EBV specific cytotoxic T-lymphocytes (EBV-CTL) and 14g2a.zeta transduced autologous peripheral blood T-cells
Listings of adverse events by patients will include the time to onset, the duration of each event, the severity of each event, and the relationship of the event to study therapy, whether it was a serious event, and whether it caused withdrawal.
15 yrs
Secondary Outcomes (3)
Determine the differential survival and function of these two infused cell-types in vivo, in particular to determine if chimeric receptor transduced EBV-CTLs survive longer than transduced peripheral-blood T-cells.
15 yrs
Determine anti-tumor effects of transduced peripheral blood T-cells and EBV specific CTLs in vivo.
15 years
Compare the differential survival of these infused cells in an additional 6 patients treated at dose level #1 without CD45 antibody mediated lymphodepletion, to patients previously treated at dose levels #2 and #3.
15 years
Study Arms (1)
EBV specific CTLs w/out lymphodepletion
EXPERIMENTALEscalating doses of 14g2a.zeta chimeric receptor transduced autologous EBV specific cytotoxic T-lymphocytes (EBV-CTL) and 14g2a.zeta transduced autologous peripheral blood T-cells administered to patients with Neuroblastoma.
