Genetically Engineered Cells (FH-FOLR1 ST CAR T Cells) for the Treatment of Advanced Refractory or Recurrent/Progressive Osteosarcoma, FIERCe Trial

This phase I trial tests the safety, side effects, and best dose of FH-FOLR1 ST chimeric antigen receptor (CAR) T cells and how well they work in treating patients with osteosarcoma that recurred or spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced) and that has not responded to previous treatment (refractory) or has come back after a period of improvement (recurrent)/is growing, spreading, or getting worse (progressive). CAR T-cell therapy is a type of treatment in which a patient's T cells (a type of immune system cell) are changed in the laboratory so they attack tumor cells. T cells are taken from a patient's blood through a process called apheresis. Then the gene for a special receptor that binds to a certain protein on the patient's tumor cells, such as FOLR1, is added to the T cells in the laboratory. The special receptor is called a CAR. Large numbers of the CAR T cells are grown in the laboratory and given to the patient by an intravenous infusion. Chemotherapy drugs, such as fludarabine and cyclophosphamide, are given to a patient before the manufactured FH-FOLR1 ST CAR T cells to make room for the CAR T cells in the blood and to enhance the CAR T cell activity in the patient. FH-FOLR1 ST CAR T cells may be safe, tolerable, and/or effective in treating patients with advanced refractory or recurrent/progressive osteosarcoma.

Targeted Therapy Directed by Genetic Testing in Treating Pediatric Patients With Relapsed or Refractory Advanced Solid Tumors, Non-Hodgkin Lymphomas, or Histiocytic Disorders (The Pediatric MATCH Screening Trial)

This phase II Pediatric MATCH screening and multi-sub-trial studies how well treatment that is directed by genetic testing works in pediatric patients with solid tumors, non-Hodgkin lymphomas, or histiocytic disorders that have progressed following at least one line of standard systemic therapy and/or for which no standard treatment exists that has been shown to prolong survival. Genetic tests look at the unique genetic material (genes) of patients' tumor cells. Patients with genetic changes or abnormalities (mutations) may benefit more from treatment which targets their tumor's particular genetic mutation, and may help doctors plan better treatment for patients with solid tumors or non-Hodgkin lymphomas.

Study of Onivyde With Talazoparib or Temozolomide in Children With Recurrent Solid Tumors and Ewing Sarcoma

The phase I portion of this study is designed for children or adolescents and young adults (AYA) with a diagnosis of a solid tumor that has recurred (come back after treatment) or is refractory (never completely went away). The trial will test 2 combinations of therapy and participants will be randomly assigned to either Arm A or Arm B. The purpose of the phase I study is to determine the highest tolerable doses of the combinations of treatment given in each Arm. In Arm A, children and AYAs with recurrent or refractory solid tumors will receive 2 medications called Onivyde and talazoparib. Onivyde works by damaging the DNA of the cancer cell and talazoparib works by blocking the repair of the DNA once the cancer cell is damaged. By damaging the tumor DNA and blocking the repair, the cancer cells may die. In Arm B, children and AYAs with recurrent or refractory solid tumors will receive 2 medications called Onivyde and temozolomide. Both of these medications work by damaging the DNA of the cancer call which may cause the tumor(s) to die. Once the highest doses are reached in Arm A and Arm B, then "expansion Arms" will open. An expansion arm treats more children and AYAs with recurrent or refractory solid tumors at the highest doses achieved in the phase I study. The goal of the expansion arms is to see if the tumors go away in children and AYAs with recurrent or refractory solid tumors. There will be 3 "expansion Arms". In Arm A1, children and AYAs with recurrent or refractory solid tumors (excluding Ewing sarcoma) will receive Onivyde and talazoparib. In Arm A2, children and AYAs with recurrent or refractory solid tumors, whose tumors have a problem with repairing DNA (identified by their doctor), will receive Onivyde and talazoparib. In Arm B1, children and AYAs with recurrent or refractory solid tumors (excluding Ewing sarcoma) will receive Onivyde and temozolomide. Once the highest doses of medications used in Arm A and Arm B are determined, then a phase II study will open for children or young adults with Ewing sarcoma that has recurred or is refractory following treatment received after the initial diagnosis. The trial will test the same 2 combinations of therapy in Arm A and Arm B. In the phase II, a participant with Ewing sarcoma will be randomly assigned to receive the treatment given on either Arm A or Arm B.

NKG2D.Zeta-NK Cell Conditioning With C7R.GD2.CAR-T Cells for Patients With Relapsed or Refractory Osteosarcoma or Neuroblastoma

The purpose of this study is to find the largest safe dose of i15.NKG2D.zeta-NK cells in combination with C7R.GD2.CAR-T cells, and additionally to evaluate how long they can be detected in patients' blood and what affect they have on patients' cancer. Patients eligible for this study have neuroblastoma or osteosarcoma that expresses a substance on the cancer cells called GD2. This cancer has either come back after treatment or did not respond to the standard or other investigational treatments or therapies used to treat it. There is no standard treatment for these types of advanced cancers at this time. This is a gene transfer research study using special immune cells called NK cells and T cells. NK cells and T cells are types of white blood cell that help the body fight infection. 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: NK cells and T cells. T cells are special infection-fighting blood cells that can kill cells infected with viruses and tumor cells. NK cells, another kind of infection-fighting cell, can recognize a wide range of cells in distress, including tumor cells and cells that help protect tumor cells in the cancer environment. Both NK cells and T cells have been used individually to treat patients with cancers. They have shown promise, but have not been strong enough individually to cure most patients. Investigators have found from previous research that we can put a new gene into T cells that will make them recognize GD2, a substance found on almost all neuroblastoma and osteosarcoma cells. We can also put a new gene into NK cells that help them fight the tumor environment. Investigators know that T cells and NK cells need substances called cytokines to survive but the cells do not get enough cytokines after infusion into the body; therefore, the investigators have added the genes C7R and IL15 into the T and NK cells, respectively, to give each cell a constant supply of cytokine that helps them to survive longer. The C7R.GD2.CAR-T cells and i15.NKG2D.zeta-NK cells are investigational products not approved by the Food and Drug Administration.
