NCT ID NCT04294628

First seen Nov 01, 2025 · Last updated May 14, 2026 · Updated 28 times

Summary

This early-phase study looks at how the drug DS-8201a affects tumor cells and the immune system in people with advanced HER2-positive cancers that have stopped responding to standard treatments. Researchers will take small tumor samples before and after treatment to measure changes in proteins and immune cells. The goal is to learn how the drug works, not to test a cure or long-term control.
