Summary

This study tests whether a simple blood test (ctDNA) can help doctors decide if adding chemotherapy to the immunotherapy drug cemiplimab works better for advanced lung cancer. About 63 people with stage IV or stage IIIB/C non-small cell lung cancer that hasn't been treated before will join. The goal is to see if this personalized approach helps people live longer.
