Genetically Engineered Cells (TROP2 CAR/IL-15 TGFBR2 KO NK Cells) after Preconditioning for the Treatment of Locally Advanced, Unresectable, Metastatic, or Recurrent Head and Neck Cancer

Trial Status: temporarily closed to accrual

This phase I trial tests the safety, side effects, and best dose of TROP2 CAR/IL-15 TGFBR2 KO NK cells after preconditioning with radiation therapy and chemotherapy for the treatment of patients with head and neck cancer that has spread to nearby tissue or lymph nodes (locally advanced), that cannot be removed by surgery (unresectable), that has spread from where it first started (primary site) to other places in the body (metastatic), or that has come back after a period of improvement (recurrent). TROP2 CAR/IL-15 TGFBR2 KO NK cells are human immune cells that have been grown and modified (changed) in the laboratory so that they will target tumor cells. To produce the TROP2 CAR/IL-15 TGFBR2 KO NK cells, natural killer cells are taken from a patient’s blood. Then the gene for a special receptor that binds to a certain protein on the patient’s tumor cells is added to the natural killer cells in the laboratory. The special receptor is called a chimeric antigen receptor (CAR). Large numbers of these cells are grown in the laboratory and given to the patient by infusion for treatment of certain tumors. Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill tumor cells and shrink tumors. Chemotherapy drugs, such as fludarabine and cyclophosphamide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Preconditioning with radiation and chemotherapy is given before treatment with TROP2 CAR/IL-15 TGFBR2 KO NK cells to help prepare the body to receive the natural killer cells.
