Summary

This trial will study using SRS and 3 drugs to treat brain mets from HER-2+ breast cancer.

Who is the study for?
This trial is for adults with HER-2 positive breast cancer that has spread to the brain. They must have 1-10 small brain metastases, good liver and kidney function, and a life expectancy of at least 12 weeks. Women who can bear children need negative pregnancy tests and must use two forms of contraception during the study.
What is being tested?
The study is testing how well stereotactic radiosurgery (SRS) works when combined with tucatinib, trastuzumab, and capecitabine in controlling brain metastases from HER-2 positive breast cancer. This combination treatment approach is experimental.
What are the potential side effects?
Possible side effects include diarrhea, liver issues reflected by blood test changes, heart problems like reduced heart pump function or irregular heartbeat, allergic reactions to any of the drugs used, as well as fatigue and low blood cell counts leading to increased infection risk.
