First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study looks at how much of the drug T-DXd enters brain tumors in people with HER2-positive brain cancers or glioblastoma. Thirty participants will receive T-DXd before surgery to remove a brain tumor, and researchers will measure drug levels in the tumor. The goal is to see if T-DXd can effectively target these hard-to-treat cancers.
