Overview
Immune checkpoint inhibitors targeting PD-1 or PD-L1 have been developed and clinical trials showning better response in unselected patients with metastatic renal cell carcinoma (RCC). At the moment, no clear biomarker exists to accurately predict anti-PD1/PDL1 RCC responsiveness. The objective of this study is to develop and evaluate the utility of circulating exosomes as companion diagnostic biomarker for predicting response to immunotherapy in patients with RCC.
