Purpose
Subjects that have relapsed or refractory neuroblastoma are invited to take part in this gene transfer research study.

We have found from previous research that we can put a new gene called a chimeric antigen receptor (CAR) into T cells that will make them recognize neuroblastoma cells and kill them. In a previous clinical trial, we used a CAR that recognizes GD2, a protein found on almost all neuroblastoma cells (GD2-CAR). We put this gene into T cells and gave them back to patients that had neuroblastoma. The infusions were safe and in patients with disease at the time of their infusion, the time to progression was longer if we could find GD2 T cells in their blood for more than 6 weeks. Because of this, we think that if T cells are able to last longer, they may have a better chance of killing neuroblastoma tumor cells.

Therefore, in this study we will add new genes to the GD2 T cells that can cause the cells to live longer. These new genes are called CD28 and OX40. As a safety precaution we will also include another gene that can be activated to destroy the T cells in case there are unexpected or unwanted side effects. This "safety gene" is called iC9 and is turned on by a medication called AP1903.

The purpose of this study will be to determine the highest dose of iC9-GD2-CD28-OX40 (iC9-GD2) T cells that can safely be given to patients with relapsed/refractory neuroblastoma.

Primary Outcome Measures:
Dose limiting toxicities at 6 weeks post T cell infusion [ Time Frame: 6 weeks after infusion of the last dose of iC9-GD2 T cells to all patients on the study ] [ Designated as safety issue: Yes ]
We will measure and assess the adverse events to find the maximum tolerated dose of iC9-GD2 T cells and the safety profile of iC9-GD2 T cells.

Effects of AP1903 administration [ Time Frame: 6 weeks after infusion of the last dose of iC9-GD2 T cells to all patients on the study ] [ Designated as safety issue: Yes ]
Blood will be evaluated to measure the effect of T cell elimination after administration of the dimerizing drug.


Secondary Outcome Measures:
To evaluate the expansion and persistence of 3rd generation iC9-GD2 T cells [ Time Frame: 15 years ] [ Designated as safety issue: No ]
We will determine the expansion and functional persistence of iC9-GD2 T cells in the peripheral blood of patients using transgene detection by quantitative real-time PCR and response of transgenic cells to tumor antigen and to dimerizing drug in vitro.

Time to progression of disease [ Time Frame: 15 years ] [ Designated as safety issue: No ]
To describe the overall response rate and disease-free survival.

Change in serum cytokine and chemokine levels [ Time Frame: 15 years ] [ Designated as safety issue: No ]
The changes in patients' serum cytokine and chemokine levels after iC9-GD2 T cell infusion


Estimated Enrollment: 14
Study Start Date: May 2013
Estimated Study Completion Date: May 2030
Estimated Primary Completion Date: May 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: iC9-GD2 T Cell Lymphocytes
The iC9-GD2 transduced T cells will given IV over 5-10 minutes. There is a possibility for additional doses of iC9-GD2 T cells.
Genetic: iC9-GD2 T Cell Lymphocytes
Subjects will receive the iC9-GD2 T cells through an IV over 5 to 10 minutes. Subjects will receive one of the following dose levels (cells/m2):

Dose Level 1 = 1 x 10^7
Dose Level 2 = 1 x 10^8
Dose Level 3 = 2 x 10^8
Six weeks after the infusion, patients will have a disease re-evaluation. If the disease has not gotten worse AND they have not had a severe side effect caused by the infusion of the iC9-GD2 T cells, the subject may be eligible to receive up to 2 additional doses of T cells. Each dose will be at the same dose level as the first infusion, if available, and separated by at least 6 weeks.

Other Names:
gene transfer
chimeric antigen receptor
CD28
OX40
Drug: AP1903
If there is development of Grade 3 or greater toxicity attributed to the infusion of iC9-GD2 T cells, we will administer a single dose of dimerizer drug (0.4mg/Kg I.V.) and measure the effects on circulating gene modified T cells and the associated toxicity.

Detailed Description:
We will make iC9-GD2 T cells by infecting normal T cells with a retroviral vector containing the iC9-GD2 gene. After the new gene has been put into the T cells, the cells will be tested to make sure that they kill GD2-positive neuroblastoma cells and then frozen until the patient is ready for their infusion.

The infusion will be given by the Center for Cell and Gene Therapy at Texas Children's Hospital in Houston, Texas. The injection will take between 5 and 10 minutes, but patients should expect to remain in Houston for the first few weeks after the infusion just in case we need to give AP1903 to turn on the safety switch within the cells.

There will be follow-up visits every 1-2 weeks during the first 2 months and then they will be spaced out over a total of 15 years. Because the cells are modified with a new gene we must follow patients for at least 15 years to see if there are any long term side effects of gene transfer. During the visits, we will see how the patients are doing and during certain time points we will obtain extra blood samples to learn more about the way the iC9-GD2 T cells are working and how long they last in the body.
