A Clinical Study on the Safety, Tolerability and Efficacy of Neoantigen-based Personalized mRNA Therapy iNeo-Vac-R01 Plus PD-1 Inhibitor in Adjuvant Treatment of Liver Cancer Post Radical Resection
China20 participantsStarted 2025-09-11
Plain-language summary
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.

Inclusion criteria
✓. Aged 18 to 75 years old (at the time of signing the informed consent form).
✓. Patients with histopathologically or cytologically confirmed hepatocellular carcinoma (HCC) eligible for radical resection; no tumor thrombus in the portal vein, hepatic vein or bile duct on pre-operative imaging; for multinodular patients, the number of tumor nodules ≤ 3 and no extrahepatic metastasis; clear margins of all tumor nodules and negative surgical margins after radical resection.
✓. High risk of postoperative recurrence, where high risk is defined as a single tumor lesion with microvascular invasion, or 2-3 tumor lesions; intermediate risk is defined as a single tumor lesion with a diameter \> 5 cm and no microvascular invasion.
Exclusion criteria
✕. Expected survival time of at least 6 months.
✕. Eastern Cooperative Oncology Group (ECOG) performance status score of 0 or 1.
✕. Sufficient tumor tissue samples can be obtained for genetic analysis: for puncture samples, at least 2 core biopsy tissues with tumor purity ≥ 50%; for surgical samples, a soybean-sized tissue sample.
