Immunoscore IC is a novel assay designed to help predict a patient’s response to immune checkpoint inhibitors. The assay measures the densities of PD-L1+ and CD8+ cells, as well as the proximity among these cells on a single tissue section using imaging tools, and then produces a risk score based on a proprietary algorithm. The Immunoscore IC assay is available as a service for biopharmaceutical companies and is part of the Immunoscore family of assays. These assays measure the immune reaction in and around the tumor and help to determine drugs’ mechanisms of action and their impact on the tumor microenvironment (TME).
