BackgroundImmune checkpoint inhibitors (ICIs) targeting the programmed death (ligand)-1 (PD-1/PD-L1) axis, like pembrolizumab, have significantly improved survival in non-small cell lung cancer (NSCLC). However, less than 50% of patients respond. Identifying early-response biomarkers is crucial to personalize therapy, thereby preventing ineffective, expensive and potentially harmful treatment. MethodsWe applied a novel ex vivo immunopharmacological bioassay to assess pembrolizumab-dependent T c...
