Summary

This study is for people with advanced HER2-positive breast cancer whose current treatment (trastuzumab deruxtecan) has stopped working. Researchers want to see if switching immediately to another targeted drug (trastuzumab emtansine) can help control the cancer longer. About 100 participants in Korea will be followed to track how long the cancer stays under control and how well the new drug works.
