About this trial
This study primarily aims to assess the safety and tolerability of XP-004 personalized mRNA vaccines encoding tumor neoantigens combined with PD-1 inhibitor as adjuvant therapy for chemotherapy-intolerant patients following radical pancreatic cancer resection.
Secondary objectives focus on evaluating preliminary efficacy through three parameters: 1) XP-004-induced antigen-specific CD4+/CD8+ T cell activation levels, 2) recurrence-free survival (RFS), and 3) overall survival (OS) in post-operative pancreatic cancer patients receiving this combination therapy.
