iNeo-Vac-R01, a personalized neoantigen-based mRNA therapeutic technology for tumors, is a customized neoantigen mRNA injectable formulation developed by collecting patients' tumor tissues and peripheral blood, screening appropriate neoantigens via high-throughput sequencing, and encapsulating these neoantigens into mRNA liposomes. It can precisely induce the proliferation of patient-specific T cells to eliminate tumor cells. This tumor therapeutic approach that harnesses the body's own immune system features high efficacy and low toxicity, with milder treatment responses and no severe adverse reactions for patients. This study aims to provide a novel personalized therapeutic strategy for the adjuvant treatment of post-operative liver cancer patients, with the research objectives of prolonging their disease-free survival (DFS) and overall survival (OS) following surgery.
