Personalized Neoantigen Vaccine Plus IL-12 (INO-9012) Versus Active Surveillance in Subjects With High-Risk HCC (IMPACT31)

3. september 2026 opdateret af: Geneos Therapeutics

IMPACT31: A Randomized Open-label, Multi-center, Phase II Adjuvant Study of a Personalized Neoantigen DNA Vaccine (GNOS-PV02) and Plasmid Encoded IL-12 (INO-9012) Versus Active Surveillance in Subjects With High-Risk HCC

This is a randomized, open-label, multi-site Phase II study of a personalized neoantigen DNA vaccine (GNOS-PV02) and plasmid encoded IL-12 (INO-9012) in subjects with histologically or cytologically confirmed diagnosis of HCC based on pathology report, who were eligible to undergo definitive resection, have demonstrated laboratory, radiographic and/or pathologic high-risk criteria for recurrence (described under eligibility), have no evidence of disease (NED) as per MRI approximately 28 days post resection, and are able to provide a tissue sample for personalized neoantigen DNA vaccine development.
