Autologous Neoantigen-Specific T-Cell Therapy for Advanced Hepatocellular Carcinoma

Официальное название

Feasibility, Safety and Efficacy Study of Autologous Neoantigen-Specific T-Cell Therapy (iNeo-Vac-T01) in Advanced Hepatocellular Carcinoma Patients

Обзор

The goal of this open-label, single-arm phase I/II clinical trial is to evaluate the feasibility, safety, and anti-tumor efficacy of the autologous neoantigen-specific T-cell therapy (iNeo-Vac-T01) in patients with advanced hepatocellular carcinoma who have failed second-line or later systemic therapies.
