Tucatinib and Trastuzumab for Previously Treated Human Epidermal Growth Factor Receptor 2–Positive Metastatic Biliary Tract Cancer (SGNTUC-019): A Phase II Basket Study
A Phase II basket study looking at tucatinib + trastuzumab in mBTC, only 30 patients were studied as this is a small subpopulation. However, the results were compelling, with an ORR of 47%. For a 3L patient who has failed gem/cis and FOLFONI, this would be a targeted option to consider.
