Abstract CT114: Nivolumab versus docetaxel in a predominantly Chinese patient population with previously treated advanced non-small cell lung cancer (NSCLC): results of the phase 3 CheckMate 078 study

Introduction: Lung cancer incidence in China has increased and it remains the leading cause of cancer death, highlighting a need for new treatments. We report results from CheckMate 078, the first phase 3 study of an anti-programmed death (ligand) 1 (PD-[L]1) agent in predominantly Chinese patients with NSCLC and disease progression after platinum (Pt)-based chemotherapy. Methods: Patients who had disease progression during or after Pt-based doublet chemotherapy were randomized 2:1 to receive nivolumab (3 mg/kg Q2W) or docetaxel (75 mg/m2 Q3W). Patients were included regardless of tumor histology or PD-L1 expression, and randomization was stratified according to both of these factors (≥1% vs Results: 639 patients were enrolled from December 2015 to December 2016; 504 were randomized. Of all randomized patients, ~90% were from China, 60% had non-squamous tumor histology; tumor PD-L1 expression was Conclusions: In this population of patients with advanced NSCLC previously treated with Pt-based chemotherapy, nivolumab demonstrated superior OS, PFS, and ORR compared with docetaxel. Efficacy and safety of nivolumab in this first randomized controlled trial of nivolumab in NSCLC in a predominantly Chinese patient population were consistent with the results of the pivotal global CheckMate 017/057 studies.
