Purpose

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.
