Abstract Immune checkpoint inhibitors (ICI) targeting the PD-1 pathway have transformed treatment of advanced renal cell carcinoma (RCC), but mechanisms underlying therapeutic response remain largely unknown. Herein, we perform transcriptomic analysis on RCC biospecimens from 102 patients enrolled in a phase II clinical trial frontline nivolumab (NCT03117309) to investigate determinants anti-PD1 monotherapy. Through bulk analysis, identify an enrichment genes associated with tertiary...
Abstract Purpose: Programmed cell death protein 1 (PD-1) expression on CD8+TIM-3−LAG-3− tumor-infiltrating cells predicts positive response to PD-1 blockade in metastatic clear-cell renal carcinoma (mccRCC). Because inhibition of signaling regulatory T (Treg) augments their immunosuppressive function, we hypothesized that Tregs would predict resistance inhibitors. Experimental Design: PD-1+ were phenotyped using multiparametric immunofluorescence ccRCC tissues from the CheckMate-025 trial...
