About This Trial

This is a Phase 3 Randomized, double-blind, Multiregional Study of Ivonescimab Combined with Chemotherapy Versus Pembrolizumab Combined with Chemotherapy for the First-line Treatment of Metastatic Non-small Cell Lung Cancer. The primary endpoint is overall survival and progression free survival assessed by investigator. The key secondary endpoints include response and safety.

More detail

This study consists of two distinct NSCLC histology cohorts: squamous (N=600) and non-squamous (N=1000), approximately 1600 patients in total. Within each cohort, subjects are randomized in a 1:1 ratio into one of two treatment groups, receiving either ivonescimab or pembrolizumab combined with platinum-doublet chemotherapy. The two histology cohorts will be analyzed independently
