Sequencing Antibody Drug Conjugates in ER+/HER2 LOW/ULTRA LOW MBC

Summary

The purpose of this research study is to see if the medication sacituzumab govitecan (SG) is effective at the currently approved dose and schedule in people who have previously received trastuzumab deruxtecan (T-DXd) for the treatment of metastatic, hormone receptor positive (HR+)/human epidermal growth factor 2 low (HER2 low) breast cancer. Although SG is approved to treat metastatic HR+/HER2 negative breast cancer, the aim of this study is to determine if SG is still effective specifically in people who have already received T-DXd.
