Summary

This trial is testing whether a combination of two drugs is better than just one of the drugs for overall survival and progression-free survival in people with a certain kind of cancer.

Who is the study for?
This trial is for adults with Stage IV non-small cell lung cancer (NSCLC) showing PD-L1 expression in at least 1% of tumor cells. Participants must not need EGFR-, ALK-, or ROS1-directed therapy, have a life expectancy of over 3 months, and an ECOG score of 0-1. Women must use effective contraception or be abstinent, and all participants should have adequate organ function.
What is being tested?
The study tests if a combination drug (pembrolizumab/vibostolimab) is more effective than pembrolizumab alone in improving survival without cancer progression. It focuses on patients whose tumors express the protein PD-L1 to varying degrees and measures overall survival and disease progression.
What are the potential side effects?
Potential side effects include allergic reactions to the drugs' components, immune system-related issues such as inflammation in various organs, fatigue, possible infections due to lowered immunity, and complications related to pre-existing conditions like pneumonitis.
