Phase II trial shows combination of tucatinib and trastuzumab effective in 46.7% bile duct cancer patients; further research needed.

A phase II trial suggests that the combination of tucatinib and trastuzumab, drugs targeting the HER2 protein, may be effective for patients with bile duct cancer. Among 30 bile duct cancer patients, 46.7% experienced tumor shrinkage, while the overall response rate was 22.2% across 217 participants. The treatment was well-tolerated, but further research is needed to validate these findings and potentially include the drug combination in clinical guidelines for HER2-positive bile duct cancer.
