5. Study Description

Brief Summary
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. 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. In other clinical studies using T cells, some investigators found that giving chemotherapy before the T cell infusion can improve the amount of time the T cells stay in the body and therefore the effect the T cells can have. This is called lymphodepletion and we think that it will allow the T cells we infuse to expand and stay longer in the body, and potentially kill cancer cells more effectively. The chemotherapy we will use for lymphodepletion is a combination of cyclophosphamide and fludarabine. Additionally, to effectively kill the tumor cells, it is important that the T cells are able to survive and expand in the tumor. Recent studies have shown that solid tumors release a substance (PD1) that can inhibit T cells after they arrive into the tumor tissue. In an attempt to overcome the effect of PD1 in neuroblastoma we will also give a medication called pembrolizumab.
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 will be either given fresh or frozen until the patient is ready for their infusion. First, patients will receive cyclophosphamide and fludarabine intravenously (through a needle inserted into a vein or your port-a-cath) for 2 days and then fludarabine alone for one day (Day -4, -3,-2). On the next day (Day -1) patients will receive the drug called pembrolizumab intravenously. Finally on Day 0 patients will be given an infusion of iC9 GD2 T cells into the vein through an IV line at the assigned dose. The iC9-GD2 T cell infusion will be given by the Center for Cell and Gene Therapy at Texas Children's Hospital or Houston Methodist Hospital. The infusion will take between 5 and 10 minutes. Patients may need to stay in Houston for up to 4 weeks after the infusion so we can monitor them for side effects. On Day 21 (at the time of the week 3 visit), if the treatment was well tolerated, patients will receive another dose of pembrolizumab intravenously. 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. After disease re-evaluation, if disease has not gotten worse, or if in the future it seems that patient might benefit and they have not had a severe side effect caused by the infusion of their iC9-GD2 T cells, patients may be eligible to receive up to 2 additional doses of their T cells. Each dose will be at the same dose level as their first infusion and separated by at least 6 weeks such that we can make sure patients have no severe side effects between infusions. If patients receive additional doses of iC9-GD2 T-cells, they may need to stay in Houston for up to 4 weeks after the infusion as well so we can monitor them for side effects. If there were no severe side effects from pembrolizumab, patients will receive pembrolizumab again with the iC9 GD2 T cells on the day before the T cell injection and 21 days after the T cells.
