|Experimental: Pexa-Vec combined with Nivolumab||
Biological: Pexastimogene Devacirepvec (Pexa Vec)
Pexa-Vec (pexastimogene devacirepvec) will be administered as 3 bi-weekly intratumoral (IT) injections of 10^9 pfu at day 1 and weeks 2 and 4
Nivolumab will be administered intravenously every 2 weeks (from week 2)
- Phase I part: To evaluate the safety profile of intratumoral (IT) Pexa-Vec combined with intravenous (IV) nivolumab in patients with advanced HCC. Dose Limiting Toxicities (DLTs) [ Time Frame: 4 weeks ]
DLTs are defined as the occurrence of any of the following events evaluated as related to study drugs and occurring during the first 4 weeks:
- All Grade 3-4 non-hematologic toxicity that represent a 2-grade increase over baseline, excluding: inadequately treated nausea, vomiting and diarrhea, alopecia, transient fatigue and laboratory/metabolic abnormalities.
- Any Grade ≥ 3 treatment-related acute immune-related AE involving major organs.
- Grade ≥ 3 injection site reaction.
- AST or ALT ≥ 10xULN, unless it is related to a definite progression of liver metastases or another clearly identifiable etiology; doubling of AST or ALT that is concurrent with a doubling of the total bilirubin.
- Any toxicity related to study therapy that results in a delay in treatment of 2 or more weeks.
- Neutropenia lasting for more than 7 days; Neutropenic fever; Grade 4 thrombocytopenia or grade 3 thrombocytopenia with clinically significant bleeding.
- Phase IIa part: To evaluate the anti-tumor activity and efficacy of IT Pexa-Vec combined with IV nivolumab in patients with advanced HCC with respect to Overall Response Rate (ORR) (RECIST 1.1). [ Time Frame: 6 months ]Overall response rate (ORR): proportion of patients, whose best overall response is either CR or PR, confirmed at least 4 weeks after initial documentation.
- Disease Control Rate (DCR) at 4 months [ Time Frame: 4 months ]4-month DCR: proportion of patients whose best overall response in the study is either CR, PR, or stable disease (SD) 4 months after D1.
- Overall Survival (OS) [ Time Frame: every 3 months up to 1 year ]Proportion of patients alive at specified time points
