NY-ESO-1 TCR-T Cells for NY-ESO-1 Positive Subjects With Advanced Solid Tumors

Summary

New York Esophageal Squamous Cell Carcinoma 1 (NY-ESO-1) is a cancer-testis antigen (CTA) which is expressed in various tumors. In TCR-T therapy, researchers take the blood of a certain patient, select T cells and insert genes into the cell that expressing a kind of protein that targeting NY-ESO-1. The genetically engineered cells are called NY-ESO-1 TCR-T cells. Then the engineered cells are re-infused to the cancer patients to cure the disease or prolong life.
