New pill takes on hard-to-treat lung cancer in major trial
NCT ID NCT07242274
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a new targeted drug, JMKX001899, against standard chemotherapy (docetaxel) in people with advanced non-small cell lung cancer that has a specific genetic change called KRAS G12C. About 472 adults who have already tried at least one prior treatment will be randomly assigned to receive either the new drug or chemotherapy. The goal is to see if the new drug works better at slowing cancer growth and has fewer side effects.
