Blood test could guide lung cancer treatment without invasive biopsies
NCT ID NCT04223596
First seen Feb 04, 2026 · Last updated May 13, 2026 · Updated 19 times
Summary
This study looks at whether a simple blood test (liquid biopsy) can help doctors monitor how well the drug brigatinib is working in people with a specific type of advanced lung cancer (ALK-positive non-small cell lung cancer). About 33 patients who have not had chemotherapy before will take brigatinib pills daily until their cancer worsens or side effects become too much. The main goal is to see how many patients' tumors shrink, and the blood test results will be compared to standard scans to see if it's a reliable way to track the cancer over time.
