NCT ID NCT04784221
First seen Jun 25, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This study aimed to test whether combining special nanoparticles with proton radiation could help control cancers that return after previous radiation treatment. The trial was planned for adults with tumors in specific areas like the skull base or throat. However, the study was withdrawn before any patients were enrolled, so no data was collected.
