Lung cancer relapse mystery: new study digs into genetic clues
NCT ID NCT07363252
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at 100 people with a specific type of lung cancer (EGFR-mutated NSCLC) whose cancer came back during or after treatment with the drug osimertinib. Researchers want to find out what new genetic changes appear when the cancer returns. This is an observational study, meaning no new treatment is given—just analysis of tumor samples to better understand why resistance happens.
