Abstract Background Anti-PD-1 and PD-L1 (collectively PD-[L]1) therapies are approved for many advanced solid tumors. Biomarkers beyond immunohistochemistry, microsatellite instability, tumor mutation burden (TMB) may improve benefit prediction. Methods Using treatment data genomic transcriptomic tissue profiling from an observational trial (NCT03061305), we developed Immunotherapy Response Score (IRS), a pan-tumor predictive model of PD-(L)1 benefit. IRS real-world progression free survival...

Immunotherapy response score (IRS) integrates tumor mutation burden (TMB) and quantitative expression biomarkers to predict anti-PD-1/PD-L1 [PD-(L)1] monotherapy benefit. Here, we evaluated IRS in additional cohorts. Patients from an observational trial (NCT03061305) treated with anti-PD-(L)1 were included assigned IRS-High (-H) versus -Low (-L) groups. Associations real-world progression-free survival (rwPFS) overall (OS) determined by Cox proportional hazards (CPH) modeling. Those...
