Phase 3 Study Comparing Pumitamig and Pembrolizumab as First Treatment in Adults With Advanced Non-Small Cell Lung Cancer and High PD-L1 Levels

What this Trial Is About

Researchers are evaluating the effectiveness of Pumitamig compared to Pembrolizumab in adults with previously untreated advanced Non-Small Cell Lung Cancer NSCLC who have a PD-L1 expression level of 50% or higher. This Phase 3 randomized, double-blind study focuses on patients with locally advanced or metastatic NSCLC to better understand first-line treatment options. Participants receive either Pumitamig or Pembrolizumab as the study drug, given at specified doses on certain days. The study uses a parallel design with two treatment groups to compare these therapies as first-line options. The study is planned to continue until October 2031, with treatment and follow-up periods extending up to approximately 5 years for overall survival assessments. During the study, participants will have regular assessments to monitor disease progression and response to treatment using criteria like RECIST v1.1. Researchers will evaluate progression-free survival, overall survival, objective response rates, duration of response, disease control rate, and symptom changes related to lung cancer over time. Safety and treatment effects will be closely monitored throughout the study duration.
