This oral targeted therapy is a HER2-specific tyrosine kinase inhibitor used in combination with trastuzumab and capecitabine to treat HER2-positive breast cancer that has spread to the brain or other parts of the body, particularly after prior HER2-based therapy. It is notable for its ability to penetrate the blood-brain barrier, making it effective against brain metastases. Diarrhea and liver enzyme elevations are common side effects that require monitoring.
