First seen Jan 03, 2026 · Last updated May 12, 2026 · Updated 16 times

Summary

This study looks at how the drug tucatinib enters and works in HER2+ brain tumors before they are surgically removed. Researchers want to understand why some cancer cells stop responding to treatment. Nine adults with HER2+ breast, lung, stomach, or colorectal cancer that has spread to the brain will take tucatinib before surgery, and their tumor tissue will be analyzed for genetic differences.
