Randomized clinical trial of pembrolizumab vs chemotherapy for previously untreated Chinese patients with PD-L1-positive locally advanced or metastatic non-small-cell lung cancer: KEYNOTE-042 China Study.

ABSTRACT: In the global KEYNOTE-042 study (Clinicaltrials.gov, NCT02220894), pembrolizumab significantly improved overall survival (OS) vs chemotherapy in patients with previously untreated programmed death ligand 1 (PD-L1)-positive locally advanced/metastatic non-small-cell lung cancer (NSCLC) without EGFR/ALK alterations. We present results from patients in KEYNOTE-042 enrolled from China in the global or extension study (NCT03850444; protocol identical to global study). Patients were randomized 1:1 (stratified by ECOG performance status 0 vs 1, squamous vs nonsquamous histology and PD-L1 tumor proportion score [TPS] ≥50% vs 1%-49%) to 35 cycles of pembrolizumab 200 mg every 3 weeks (Q3W) or investigator's choice of 4 to 6 cycles of carboplatin plus paclitaxel or pemetrexed Q3W with optional pemet
