Summary

This trial will see if tucatinib and T-DXd work better together than T-DXd alone to treat HER2+ breast cancer.

See full description
Who is the study for?
This trial is for people with HER2+ breast cancer that's spread or can't be fully removed by surgery. They should have had prior treatment with a taxane and trastuzumab, measurable disease, and treated brain metastases if present. Excluded are those who've recently used certain drugs like Lapatinib, have serious heart or lung conditions, active infections, liver diseases, or can't take pills.Check my eligibility
What is being tested?
The study tests how well tucatinib works alongside trastuzumab deruxtecan (T-DXd) in treating HER2+ breast cancer. All participants will receive both medications to see their effectiveness and monitor any side effects when combined.See study design
What are the potential side effects?
Possible side effects from tucatinib and T-DXd may include reactions at the infusion site, fatigue, nausea, changes in blood counts leading to increased infection risk or bleeding problems. There might also be specific organ-related issues such as inflammation of the lungs.
