Efficacy and safety of Programmed Death Ligand 1 inhibitors versus Programmed Death 1 inhibitors in the first-line treatment of advanced non-small cell lung cancer: a meta-analysis of randomized controlled trials.
PD-1 Inhibitors Plus Chemotherapy Outperform PD-L1 Combinations in Survival for Advanced NSCLC — In a meta-analysis of 28 randomized controlled trials, PD-1 inhibitors combined with chemotherapy were associated with meaningfully better overall survival and progression-free survival than PD-L1 inhibitors combined with chemotherapy — approximately 26% higher risk of death (HR 1.26, 95% CI 1.13–1.41) and 21% higher risk of progression (HR 1.21, 95% CI 1.06–1.38) for the PD-L1 combination — challenging the assumption that these two checkpoint inhibitor classes are clinically interchangeable in first-line treatment.
