Tumor gene expression analysis of synovial sarcoma patients treated with NY-ESO-1 TCR T cells (NCT01343043) [Immune]

ABSTRACT: Autologous T cells transduced to express a high affinity T-cell receptor specific to NY-ESO-1 (letetresgene autoleucel, lete-cel) show promise in the treatment of metastatic synovial sarcoma, with 50% overall response rate. Biomarkers predictive of response and resistance remain to be better defined. In 45 synovial sarcoma patients, we analyzed the association of response to lete-cel (NCT01343043) with tumor gene expression. Analysis of tumor samples post-treatment illustrated lete-cel infiltration and decreased expression of macrophage genes, suggesting remodeling of the tumor microenvironment.
