New breast cancer trial adapts treatment based on early response

NCT ID NCT07340398

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This phase 2 trial is for people with HER2-positive early breast cancer. After initial standard therapy, those who don't respond well will switch to a stronger combination of newer drugs, including trastuzumab-rezetecan and pyrotinib. The goal is to see if this personalized approach can eliminate more cancer before surgery and reduce side effects. About 200 participants will be enrolled.
