First seen Jun 30, 2026 · Last updated Jul 01, 2026 · Updated 1 time

Summary

This phase 3 trial compares a new drug, SHR-A1811, to the standard treatment T-DM1 in women with HER2-positive breast cancer who still have cancer cells after initial therapy. The goal is to see if SHR-A1811 can better prevent the cancer from coming back. Participants receive either drug after surgery, and researchers track how long they remain cancer-free.
