简要总结
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.
