Description of intervention(s) / exposure
Treatment: Other - Pexastimogene Devacirepvec (Pexa Vec)
Treatment: Drugs - Sorafenib

Experimental: Pexa-Vec followed by Sorafenib - Pexa-Vec (pexastimogene devacirepvec) will be administered as 3 bi-weekly intratumoral (IT) injections of 1e9 pfu at day 1 and weeks 2 and 4, followed by sorafenib at Week 6.

Active comparator: Sorafenib - Sorafenib (400 mg twice daily) begins on Day 1.


Treatment: Other: Pexastimogene Devacirepvec (Pexa Vec)
Pexa-Vec is a vaccinia virus based oncolytic immunotherapy designed to stimulate the immune system following infection and replication within tumor cells.

Treatment: Drugs: Sorafenib
Sorafenib belongs to the pharmacotherapeutic group of antineoplastic agents, protein kinase inhibitors, ATC code: L01XE05.

Sorafenib is a multi-kinase inhibitor which has demonstrated both anti-proliferative and anti-angiogenic properties in vitro and in vivo.

Sorafenib is approved for the treatment of advanced HCC and is the Standard Of Care for this disease.
