Ivonescimab plus gemcitabine and cisplatin as first-line therapy for advanced biliary tract cancer: a multicenter, open-label phase 2 trial

Listen to this summary

This phase II trial aimed to evaluate the efficacy and safety of ivonescimab combined with gemcitabine and cisplatin as a first-line treatment for patients with advanced biliary tract cancer (aBTC). The study found a promising objective response rate of 66.7% and a median overall survival of 16.8 months, suggesting that this regimen may be a viable option for treatment-naive patients with unresectable aBTC. Additionally, the research identified MAP2K7 as a potential biomarker for resistance, which could inform future therapeutic strategies.
