New hope for advanced breast cancer: experimental drug targets tumors after other treatments fail
NCT ID NCT04829604
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests an experimental drug called ARX788 in people with HER2-positive breast cancer that has spread and no longer responds to standard treatments. About 72 adults will receive the drug to see if it shrinks tumors and how long that effect lasts. The goal is to find a new option for controlling the disease when other therapies stop working.
