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. Earlier, the patient gave us blood to make 14g2a chimeric receptor-T cells and 14g2a chimeric receptor-EBV CTLs in the laboratory. These cells were grown and frozen for the patient. The patient received treatment with these cells. However, there are enough cells remaining that we are able to offer to treat the patient with an additional dose if they would like. As with the original treatment, the patient will be given an injection of cells into the vein through and IV. Before the injection is received, the patient will be given a dose of Benadryl and Tylenol. The injection will take about 2 minutes. We will follow the patient in the clinic after the injection for 3 hours. The treatment will be given by the Center for Cell and Gene Therapy at Texas Children's Hospital. Medical tests before treatment-- Before being treated, the patient will receive a series of standard medical tests: * Physical exam * Blood tests to measure blood cells, kidney and liver function * Measurements of tumor by scans and bone marrow studies if the bone marrow may show evidence of disease Medical tests during and after treatment: The patient will receive standard medical tests when they are getting the infusions and after: * Physical exams * Blood tests to measure blood cells, kidney and liver function * Measurements of tumor by scans and bone marrow studies if the bone marrow had evidence of disease 6 weeks after each infusion Because the patient has received cells with a new gene in them the patient will be followed for a total of 15 years to see if there are any long term side effects of gene transfer. If they have a procedure related to their tumor (for example a biopsy or tumor resection), we will request permission to obtain a tissue sample. This will help investigators learn more about T cell and CTL treatment of neuroblastoma. In the event of death, we will request permission to perform an autopsy to learn more about the effects of these infusions on the disease.

Protocol

This section provides details of the study plan, including how the study is designed and what the study is measuring.
Design Details
19 patients to be enrolledTotal number of participants that the clinical trial aims to recruit.
Treatment Study
These studies test new ways to treat a disease, condition, or health issue. The goal is to see if a new drug, therapy, or approach works better or has fewer side effects than existing options.

How participants are assigned to different groups/arms
In this clinical study, all participants receive the same treatment. Since there is only one group, there is no need for randomization or assignment to different arms. This type of study is often used to test a new treatment without comparing it to another.

Other Ways to Assign Participants
Randomized allocation
: Participants are assigned randomly, like flipping a coin, to ensure fairness and reduce bias.

Non-randomized allocation
: Participants are assigned based on specific factors, such as their medical condition or a doctor's decision.

How treatments are given to participants
In this study, all participants receive the same treatment. This approach is often used to evaluate the effects of a single intervention without comparing it to another.

Other Ways to Assign Treatments
Parallel assignment
: Participants are split into separate groups, each receiving a different treatment.

Cross-over assignment
: Participants switch between treatments during the study.

Factorial assignment
: Participants receive different combinations of treatments.

Sequential assignment
: Participants receive treatments one after another in a specific order, possibly based on individual responses.

Other assignment
: Treatment assignment does not follow a standard or predefined design.

How the effectiveness of the treatment is controlled
In a non placebo-controlled study, no participants receive an inert substance (placebo) to compare outcomes. Instead, all participants receive either the experimental treatment or an alternative treatment (often the Standard of Care). This method allows researchers to compare the effects of the experimental treatment with those of a different active intervention, rather than a placebo.

Other Options
Placebo-Controlled
: A placebo is used to compare the effects of the experimental treatment with those of an inert substance, isolating the true treatment effect.

How the interventions assigned to participants is kept confidential
Everyone involved in the study knows which treatment is being given. This is typically used when it's not possible or necessary to hide the treatment details from participants or researchers.

Other Ways to Mask Information
Single-blind
: Participants do not know which treatment they are receiving, but researchers do.

Double-blind
: Neither participants nor researchers know which treatment is given.

Triple-blind
: Participants, researchers, and outcome assessors do not know which treatment is given.

Quadruple-blind
: Participants, researchers, outcome assessors, and care providers all do not know which treatment is given.
