A Phase I/II Study of the Pan-immunotherapy in Patients With Local Advanced/Metastatic BTC

• Status: Unknown status
• Trial end date: 2021-08-31
• Target enrollment: 0
• Participant gender: All

Summary

Biliary tract cancer (BTC) is a rare heterogeneous collection of malignancies arising within the biliary tract, characterized by innate chemoresistance and abysmal prognosis. PD-1 blockade has been developed to a new class of cancer immunotherapy that could restore an adequate immunosurveillance against the neoplasm and enhance T-cell-mediated anticancer immune responses. Manganese has been confirmed to activate antigen-presenting cells and function as mucosal immunoadjuvants in pre-clinical studies. This open-label, phase I/II study is designed to assess the safety and efficacy of Manganese primed combined therapy of anti-PD-1 antibody and gemcitabine/cisplatin chemotherapy.
