A Phase I Study of HERV-E TCR Transduced Autologous T Cells in Patients With Metastatic Clear Cell Renal Cell Carcinoma
Background: Gene transfer is a new cancer therapy takes white blood cells from a person and grows them in a lab. The cells are changed with a virus to attack tumor cells, then returned to the person. Researchers want to see if this therapy fights kidney cancer cells. Objective: To see if gene transfer is safe and causes tumors to shrink. Eligibility: People at least 18 years old with certain kidney cancer Design: Participants will be screened with blood and urine tests. They may have: * Scans * Heart, lung, and eye tests * Lab tests * Tumor samples taken Participants will have leukapheresis. Blood will be removed by a needle in an arm. It will go through a machine that removes white blood cells. Plasma and red cells will be returned through a needle in the participant s other arm. Participants cells will be grown in the lab and genetically changed. Participants will stay in the hospital 2-3 weeks. There they will: * Get 2 chemotherapy drugs by catheter (thin plastic tube) inserted into a vein in the chest. * Get the changed cells via catheter. * Get a drug to increase white blood cell count and one to make the cells active. * Recover for about a week. * Have lab and blood tests. After leaving the hospital, participants will: * Take an antibiotic for several months. * Have leukapheresis. * Have one- or two-day clinic visits every few weeks for 2 years, and then as determined by their doctor. These will include blood and lab tests, imaging studies, and physical exam. Participants will have follow-up checks for up to 15 years.
