KEYNOTE-025: Phase 1b study of pembrolizumab in Japanese patients with previously treated programmed death ligand 1-positive advanced non-small-cell lung cancer.

ABSTRACT: Pembrolizumab, a humanized monoclonal antibody against programmed death 1 (PD-1), has been shown to improve overall survival (OS) in patients with previously treated advanced non-small-cell lung cancer (NSCLC) with programmed death ligand 1 (PD-L1) tumor proportion score (TPS) ≥1%. We report safety and efficacy results from the phase 1b KEYNOTE-025 study, which evaluated pembrolizumab in Japanese patients with previously treated NSCLC. Eligible patients had histologically/cytologically confirmed advanced NSCLC with PD-L1 TPS ≥1% and had received ≥1 platinum-doublet chemotherapy. Patients received pembrolizumab 10 mg/kg once every 3 weeks for 2 years or until disease progression/unacceptable toxicity. Primary objectives were to evaluate the safety of pembrolizumab in patients with PD-L1 TPS
