In a case of grade IV glioblastoma (GBM), we administered a combination therapy that included mRNA-DC cell vaccines, anti-PD-1 therapy, poly I:C, irradiation, chemotherapy, and surgical resection. The mRNA-DC cell vaccines, which incorporated 11 different antigens—including 7 tumor-associated antigens (TAAs)—successfully induced antigen-specific immune responses. The patient remains in a progression-free state. This case represents the first human proof-of-concept for triVAC modification, indicating that triVAC-modified mRNA-antigen-DC cell vaccines can enhance antigen immunogenicity and support the anti-cancer immune cycle.
