First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This Phase 2 trial tests whether trastuzumab rezetecan (SHR-A1811) works better than standard chemotherapy for people with HER2-Low breast cancer that has spread and is causing severe organ problems (visceral crisis). About 184 participants will receive either the new drug or a standard chemo every three weeks. The study measures how long the cancer stays under control and how well patients respond.
