TGFBR2 KO CAR27/IL-15 Natural Killer Cells for the Treatment of Relapsed/Refractory Lymphoid Cancers

Trial Status: active

This phase I trial studies the side effects and best dose of TGFBR2 KO CAR27/IL-15 natural killer (NK) cells when given after chemotherapy in treating patients with lymphoid cancers that have come back after a period of improvement (relapsed)/that do not respond to treatment (refractory). TGFBR2 KO CAR27/IL-15 NK cells is a type of treatment in which natural killer cells from donor umbilical cord blood are changed in the laboratory so they will attack cancer cells. The NK cells are taken from the umbilical cord blood. Then the gene for a special receptor that binds to a certain protein on the patient’s cancer cells is added to the NK cells in the laboratory. The special receptor is called a chimeric antigen receptor. Giving chemotherapy before TGFBR2 KO CAR27/IL-15 NK cells helps kill cancer cells in the body and helps make room for the NK cells to work. Chemotherapy drugs, such as fludarabine and cyclophosphamide, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving TGFBR2 KO CAR27/IL-15 NK cells after chemotherapy may be safe, tolerable, and/or effective in treating patients with relapsed/refractory (R/R) lymphoid cancers.
