About this study

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. In order to get them to kill cancers more effectively, in the laboratory, the study team inserted a new gene called a chimeric antigen receptor (CAR) into T cells that makes them recognize cancer cells and kill them. When inserted, this new CAR T cell can specifically recognize a protein found on solid tumors, called glypican-3 (GPC3). To make this GPC3-CAR more effective, the study team also added two genes called IL15 and IL21 that help CAR T cells grow better and stay in the blood longer so that they may kill tumors better. When the study team did this in the laboratory, they found that this mixture of GPC3-CAR,IL15 and IL21 killed tumor cells better when compared with CAR T cells that did not have IL15 plus IL21 in the laboratory. This study will use those cells, which are called 21.15.GPC3-CAR T cells, to treat patients with solid tumors that have GPC3 on thei…
