NALIRIFOX+Adebrelimab+PULSAR for Advanced Pancreatic Cancer

Summary

This study aims to evaluate the safety and preliminary efficacy of NALIRIFOX combined with adebrelimab and PULSAR as first-line treatment for locally advanced unresectable or metastatic pancreatic ductal adenocarcinoma (PDAC). Additionally, it will explore potential predictive and efficacy-related biomarkers.
