RNA sequencing could be performed on all 32 baseline and 30 on-treatment primary tumor biopsies. Based on gene-set enrichment analysis, the epithelial to mesenchymal transition signature was enriched in baseline tumors of patients without MPR, though its expression was insufficient to predict ICB response. Baseline and on-treatment IFNγ and T-cell signature expression (Z-score) were not significantly higher in patients with an MPR.­­­ Baseline primary tumor hypoxia-associated gene expression in IMCISION did not predict ICB response. However, on-treatment biopsies of MPR tumor samples showed significantly lower hypoxia gene expression when compared to non-MPR samples. Moreover, in a paired analysis of baseline and corresponding on-treatment samples, a significant decrease of hypoxia-related gene expression was observed in MPR biopsies, while this decrease was absent in non-MPR biopsies.
