HCC
Conditions
Brief summary
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.
Interventions
delivered by intradermal injection and electroporation
GNOS-PV02 + INO-9012 ID followed by electroporation
cytokine interleukin-12 (IL-12), a vaccine adjuvant

Diagnosis of immunodeficiency or is receiving systemic steroid therapy or any other form of immunosuppressive therapy within 7 days prior to the first dose of study drug 5. Diagnosed additional malignancy within 5 years prior to baseline, except for: (a) non-invasive carcinomas subject to successful curative treatment in the opinion of the investigator which require no further therapy and (b) other malignancies for which subjects have undergone potentially curative therapy and have been considered disease free for at least 3 years prior to screening. 6. Active infection requiring systemic therapy 7. Is pregnant, breastfeeding or expecting to conceive or father children within the study's projected duration 8.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Recurrence-free survival | Up to 5 years | RFS is defined as the time from randomization to any recurrence (local, locoregional, regional or distant), occurrence of new primary HCC, as assessed by the investigator, or death due to any cause, whichever occurs first. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Incidence of treatment emergent adverse events (safety and tolerability) | Up to 5 years | Summary adverse events according to CTCAE 6.0 |
| Time to extra-hepatic spread or macro-vascular invasion | Up to 5 years | Time to extra-hepatic spread or macro-vascular invasion (TTEHS/MVI) |
| Overall survival | Up to 5 years on study + 3 years follow up | OS is defined as time from randomization to death of any cause |
| RFS rate at 12, 18 and 24 months as assessed by the investigator | Randomization up to 12 months, 18 and 24 months | The proportion of patients who remain free from disease recurrence after treatment over a specified period |
| RFS rate at 12, 18 and 24 months as assessed by the BIRC | Randomization up to 12 months, 18 months and 24 months | The proportion of patients who remain free from disease recurrence after treatment over a specified period |
