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.

The main objective of this study was to observe and evaluate the safety and tolerability of mRNA-0217/S001 vaccine encoding personalized tumor neoantigens alone/in combination with Pembrolizumab injection for the treatment of advanced solid tumors. The secondary objective was to observe the preliminary efficacy of mRNA-0217/S001 personalized tumor vaccine in the treatment of advanced solid tumors with neoantigen-specific CD4+ and CD8+ T lymphocyte responses, objective tumor response rate (ORR) and disease control rate (DCR), progression-free survival (PFS) and overall survival (OS) caused by mRNA-0217/S001 personalized tumor vaccine.
