Researchers are evaluating the efficacy and safety of rilvegostomig compared to pembrolizumab monotherapy as the first-line treatment for patients with metastatic non-small cell lung cancer mNSCLC whose tumors express high levels of PD-L1. This Phase III, randomized, double-blind, multicenter global study focuses on patients with mNSCLC without certain genetic mutations who are suitable for this treatment approach. Participants are randomly assigned to receive either rilvegostomig or pembrolizumab intravenously on Day 1 of each 21-day cycle. The study compares these two drugs over repeated treatment cycles as first-line therapy. Both treatments are biological agents given by infusion, and the study is designed to monitor their effects over up to approximately five years. During the trial, participants will undergo regular assessments including physical exams, imaging scans such as CT or MRI to measure tumor lesions, and laboratory tests to evaluate organ function. Researchers will closely monitor overall survival, progression-free survival, treatment response, duration of response, and patient-reported outcomes on physical functioning and quality of life. Safety and immunogenicity of rilvegostomig will also be evaluated. Participants are followed and assessed for up to five years to gather comprehensive data on treatment effects and long-term outcomes.
