iC9-GD2-CAR-VZV-CTLs/Refractory or Metastatic GD2-positive Sarcoma and Neuroblastoma

The purpose of this study is to find the largest safe dose of GD2-T cells (also called iC9-GD2-CAR-VZV-CTLs) in combination with a varicella zoster vaccine and lymohodepleting chemotherapy. Additionally, we will learn what the side effects of this treatment are and to see whether this therapy might help patients with advanced osteosarcoma and neuroblastoma. Because there is no standard treatment for recurrent/refractory osteosarcoma and neuroblastoma at this time or because the currently used treatments do not work fully in all cases, patients are being asked to volunteer to take part in a gene transfer research study using special immune cells. The body has different ways of fighting infection and disease. No single way seems perfect for fighting cancers. This research study combines two different ways of fighting cancer: antibodies and T cells. Antibodies are types of proteins that protect the body from infectious diseases and possibly cancer. T cells, also called T lymphocytes, are special infection-fighting blood cells that can kill other cells, including cells infected with viruses and tumor cells. 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. Investigators have found from previous research that a new gene can be put into T cells that will make them recognize cancer cells and kill them. Investigators now want to see if a new gene can be put in these cells that will let the T cells recognize and kill sarcoma and neuroblastoma cells. The new gene is called a chimeric antigen receptor (CAR) and consists of an antibody called 14g2a that recognizes GD2, a protein that is found on sarcoma and neuroblastoma cells (GD2-CAR). In addition, it contains parts of the CD28 and OX40 genes which can stimulate T cells to make them live longer. Investigators have found that CAR-T cells can kill some of the tumor, but they don't last very long in the body and so the tumor eventually comes back. T cells that recognize the virus that causes chicken pox, varicella zoster virus (VZV), remain in the bloodstream for many years especially if they are stimulated or boosted by the VZV vaccine. Investigators will therefore insert the GD2-CAR gene into T cells that recognize VZV. These cells are called iC9-GD2-CAR-VZV-specific T cells but are referred to as GD2-T cells for simplicity.

B7H3 CAR T Cell Immunotherapy for Recurrent/Refractory Solid Tumors in Children and Young Adults

This is a phase I, open-label, non-randomized study that will enroll pediatric and young adult research participants with relapsed or refractory non-CNS solid tumors to evaluate the safety, feasibility, and efficacy of administering T cell products derived from the research participant's blood that have been genetically modified to express a B7H3-specific receptor (chimeric antigen receptor, or CAR) that will target and kill solid tumors that express B7H3. On Arm A of the study, research participants will receive B7H3-specific CAR T cells only. On Arm B of the study, research participants will receive CAR T cells directed at B7H3 and CD19, a marker on the surface of B lymphocytes, following the hypothesis that CD19+ B cells serving in their normal role as antigen presenting cells to T cells will promote the expansion and persistence of the CAR T cells. Arm A CAR T cells include the protein EGFRt and Arm B CAR T cells include the protein HER2tG. These proteins can be used to both track and destroy the CAR T cells in case of undue toxicity. The primary objectives of the study will be to determine the feasibility of manufacturing the cell products, the safety of the T cell product infusion, to determine the maximum tolerated dose of the CAR T cells products, to describe the full toxicity profile of each product, and determine the persistence of the modified cell in the participant's body on each arm. Participants will receive a single dose of T cells comprised of two different subtypes of T cells (CD4 and CD8 T cells) felt to benefit one another once administered to the research participants for improved potential therapeutic effect. The secondary objectives of this protocol are to study the number of modified cells in the patients and the duration they continue to be at detectable levels. The investigators will also quantitate anti-tumor efficacy on each arm. Participants who experience significant and potentially life-threatening toxicities (other than clinically manageable toxicities related to T cells working, called cytokine release syndrome) will receive infusions of cetuximab (an antibody commercially available that targets EGFRt) or trastuzumab (an antibody commercially available that targets HER2tG) to assess the ability of the EGFRt on the T cells to be an effective suicide mechanism for the elimination of the transferred T cell products.

EGFR806 CAR T Cell Immunotherapy for Recurrent/Refractory Solid Tumors in Children and Young Adults

This is a phase I, open-label, non-randomized study that will enroll pediatric and young adult research participants with relapsed or refractory non-CNS solid tumors to evaluate the safety, feasibility, and efficacy of administering T cell products derived from the research participant's blood that have been genetically modified to express a EGFR-specific receptor (chimeric antigen receptor, or CAR) that will target and kill solid tumors that express EGFR and the selection-suicide marker EGFRt. EGFRt is a protein incorporated into the cell with our EGFR receptor which is used to identify the modified T cells and can be used as a tag that allows for elimination of the modified T cells if needed. On Arm A of the study, research participants will receive EGFR-specific CAR T cells only. On Arm B of the study, research participants will receive CAR T cells directed at EGFR and CD19, a marker on the surface of B lymphocytes, following the hypothesis that CD19+ B cells serving in their normal role as antigen presenting cells to T cells will promote the expansion and persistence of the CAR T cells. The CD19 receptor harbors a different selection-suicide marker, HERtG. The primary objectives of the study will be to determine the feasibility of manufacturing the cell products, the safety of the T cell product infusion, to determine the maximum tolerated dose of the CAR T cells products, to describe the full toxicity profile of each product, and determine the persistence of the modified cell in the subject's body on each arm. Subjects will receive a single dose of T cells comprised of two different subtypes of T cells (CD4 and CD8 T cells) felt to benefit one another once administered to the research participants for improved potential therapeutic effect. The secondary objectives of this protocol are to study the number of modified cells in the patients and the duration they continue to be at detectable levels. The investigators will also quantitate anti-tumor efficacy on each arm. Subjects who experience significant and potentially life-threatening toxicities (other than clinically manageable toxicities related to T cells working, called cytokine release syndrome) will receive infusions of cetuximab (an antibody commercially available that targets EGFRt) or trastuzumab (an antibody commercially available that targets HER2tG) to assess the ability of the EGFRt on the T cells to be an effective suicide mechanism for the elimination of the transferred T cell products.

Study of CAR T-Cells Targeting the GD2 With IL-15+iCaspase9 for Relapsed/Refractory Neuroblastoma or Relapsed/Refractory Osteosarcoma

The body has different ways of fighting infections and disease. No single way seems perfect for fighting cancer. This research study combines two different ways of fighting disease: antibodies and T cells. Antibodies are molecules that fight infections and protect your body from diseases caused by bacteria and toxic substances. Antibodies work by sticking to those bacteria or substances, which stops them from growing and causing bad effects. T cells are special infection-fighting blood cells that can kill other cells, including tumor cells or cells that are infected. Both antibodies and T cells have been used to treat patients with cancers. They both have shown promise, but neither alone has been enough to cure most patients. This study is designed to combine both T cells and antibodies in order to create a more effective treatment. The treatment that is being researched is called autologous T lymphocyte chimeric antigen receptor cells (CAR) cells targeted against the disialoganglioside (GD2) antigen that express Interleukin (IL)-15, and the inducible caspase 9 safety switch (iC9), also known as iC9.GD2.CAR.IL-15 T cells. In previous studies, it has been shown that when T cells have part of an antibody attached to them they are better at recognizing and killing cancer cells. The antibody that will be used in this study is called anti-GD2. This antibody floats around in the blood and can detect and stick to cancer cells called neuroblastoma cells because they have a substance on the outside of the cells called GD2. For this study, the anti-GD2 antibody has been changed so instead of floating freely in the blood, it is now joined to the T cells. However, it is unknown how long the iC9.GD2.CAR.IL-15 T cells last in the body, so their chances of fighting cancer cells are not well known. To improve the tumor fighting power of GD2-CAR-T cells, our researchers have added two additional components to these cells. The IL-15 gene was added so that the GD2-CAR-T cells can attack tumor cells more effectively. Interleukin-15 (IL-15) is a chemical that cells use to communicate with one another. Other research using IL-15 in combination with CAR-T cells has shown there is an increase in the body's ability to allow the CAR-T cells to survive and grow in the body. The iC9 gene was added as an "off switch" so it can stop the activity of the GD2-CAR-T cells if you experience any serious bad side effects. Bad side effects seen previously in patients receiving the GD2 antibody alone include pain. In this study, the "stop switch" can be used to turn off the GD2-CAR-T cells if you experience intense pain that does not respond to normal pain treatments. The primary purpose of this study is to determine whether receiving iC9.GD2.IL-15 T cells is safe and tolerable in patients with relapsed/refractory neuroblastoma.
