Genetically Engineered Cells (NY-ESO-1 TCR/IL-15 NK cells) for the Treatment of Patients with Relapsed or Refractory Synovial Sarcoma, Myxoid Liposarcoma, or Solid Tumors

Trial Status: active

This phase I/Ib trial tests the safety, best dose, and effectiveness of NY-ESO-1 T-cell receptor (TCR)/IL-15 cord blood-derived natural killer (NK) cells after lymphodepleting chemotherapy in treating patients with NY-ESO-1 positive synovial sarcoma, myxoid liposarcoma, or other solid tumors that have come back after a period of improvement (relapsed) or that do not respond to treatment (refractory). NK cells are a type of white blood cell that destroy infected and diseased cells, such as cancer cells. To make the study product, NK cells are collected from the blood of the umbilical cord of a healthy newborn baby and then genetically modified (changed) to target certain proteins (NY-ESO-1 TCR/IL-15 cell receptors) found on the surface of multiple myeloma cancer cells and destroy the cells. Lymphodepleting chemotherapy with fludarabine and cyclophosphamide before infusion with NY-ESO-1 TCR/IL-15 NK cells helps prepare the body to receive the modified cells by destroying white blood cells known as lymphocytes.
