-
Brain MRI surveillance for HER2-positive metastatic breast cancer
This study tests whether adding regular brain MRIs helps detect hidden brain involvement earlier in people with HER2-positive metastatic breast cancer.
-
Using a pertuzumab biosimilar for HER2-positive breast cancer before surgery and as first-line treatment for metastatic disease
This project will look at how a pertuzumab biosimilar is used and how patients with HER2-positive breast cancer do when given it before surgery or as first-line treatment for metastatic disease.
-
Combining hormone therapy with chemotherapy and HER2-targeted treatment before surgery for HER2+ breast cancer
This trial will try giving hormone (endocrine) therapy at the same time as chemotherapy and HER2-targeted drugs for adults with HR+, HER2+ breast cancer to see if tumors respond better before surgery.
-
A166 for HER2-positive advanced or metastatic breast cancer
This trial will test whether A166 helps adults with HER2-positive unresectable or metastatic breast cancer who previously received a topoisomerase inhibitor–based HER2 antibody-drug conjugate.
