Tucatinib is an oral targeted therapy used to treat HER2-positive metastatic breast cancer, including cases where the cancer has spread to the brain.
It works by blocking the HER2 signaling pathway, helping slow down the growth of cancer cells.
Tucatinib is usually taken together with trastuzumab and capecitabine, especially for patients who have already tried other HER2 treatments.
This combination can improve treatment response and delay cancer progression.
This medicine must be used under the supervision of an oncologist.
