Trastuzumab plus nivolumab with gemcitabine and cisplatin as first-line therapy for HER2-positive unresectable biliary tract cancer: a phase 1b/2 trial
A phase 1b/2 trial tested trastuzumab combined with nivolumab, gemcitabine and cisplatin as first-line therapy for HER2-positive unresectable biliary tract cancer. The regimen showed encouraging clinical response rates, and HER2 expression was associated with clinical benefit. The results support HER2 status as a marker guiding trastuzumab-based treatment in this population.
Why it matters: First data on adding trastuzumab and nivolumab to standard gemcitabine-cisplatin in HER2-positive biliary tract cancer.
