Understanding resistance to T-Dxd in HER2+ breast cancer

This study looks at how well Trastuzumab Deruxtecan (T-DXd) works in Chinese women with breast cancer that has spread. It is for people whose cancer is either HER2-positive or HER2-low and who have already had some treatment.

This trial compares a targeted antibody-drug conjugate called T-DXd against standard hormone therapy for women with HR+, HER2-low advanced breast cancer that has progressed after first-line endocrine therapy plus a CDK4/6 inhibitor. It aims to see if T-DXd works better than continuing hormone therapy alone.

This trial looks at whether a different targeted therapy, T-DM1, can work for women with advanced HER2-positive breast cancer after they have already tried another targeted therapy called T-DXd (Enhertu). If you have progressed while on T-DXd and have not had more than three previous treatments for advanced cancer, you may be able to join.

This study tests a drug called T-DXd (trastuzumab deruxtecan) for people with advanced breast cancer that has very low levels of HER2 (a protein that helps cancer grow) and that is also hormone receptor positive. The goal is to see if this drug can help shrink or slow the cancer.

This study looks at how well the drug T-DXd (Enhertu) works against breast cancer that has spread or can't be removed with surgery. It includes patients with any level of HER2 protein, so it might be an option even if your cancer has low HER2.

This study follows women with advanced breast cancer (metastatic) who have hormone-receptor positive tumors and low HER2 levels, to see how well a new drug called Trastuzumab Deruxtecan works when used in routine clinical care after prior hormone therapy.
