Clinical Trial Summary

The objective of this study is to evaluate the safety/tolerability efficacy of oncolytic virotherapy combined with Tislelizumab plus lenvatinib for advanced pancreatic cancer patients who were relapsed or refractory to standard therapy

Description:

Recent studies have suggested that local destruction of tumor tissue by oncolytic virus induced activation and maturation of dendritic cells and tumor-specific T cells by cross-presentation of tumor antigens. While pd-1 blocking antibody interferes with PD-1 mediated T-cell regulatory signaling. And combination of pd-1 blocking antibody plus lenvatinib showed increased ORR in many types of human cancers. Therefore, the objective of this study is to evaluate the safety and efficacy of oncolytic virotherapy combined with Tislelizumab plus lenvatinib for advanced pancreatic cancer patients who were relapsed or refractory to standard therapy.
