Thirty-eight percent (3 of 8) of participants with evaluable paired tissue samples had a greater-than 2-fold increase from baseline in IFN-γ signature and CD274 (programmed cell death protein 1 ligand, PD-L1) expression within the tumor microenvironment (TME), which was associated with increased CD8+ T cell infiltration and decreased infiltration of CD4+ T regulatory cells. The gene discussed is CD8A; the disease is neoplasm.
