Hepatocellular Carcinoma Study Comparing Vaccinia Virus Based Immunotherapy Plus Sorafenib vs Sorafenib Alone
A Phase 3 Randomized, Open-Label Study Comparing Pexa Vec (Vaccinia GM CSF / Thymidine Kinase-Deactivated Virus) Followed by Sorafenib Versus Sorafenib in Patients With Advanced Hepatocellular Carcinoma (HCC) Without Prior Systemic Therapy
This is a randomized Phase 3 study to determine whether treatment with vaccinia virus based immunotherapy (Pexa-Vec) followed by sorafenib increases survival compared to treatment with sorafenib in patients with advanced hepatocellular carcinoma who have not received prior systemic therapy.

This is a multi-center, randomized, open-label, Phase 3 study comparing Pexa Vec followed by sorafenib versus sorafenib in patients with advanced HCC without prior systemic therapy.

A total of 600 patients will be randomly assigned to 2 treatment arms in a 1:1 ratio (300 in each arm) to reach at least 570 evaluable patients.

Phase 3
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Hepatocellular Carcinoma (HCC)
  • Biological: 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.
    Other Name: JX-594
  • Drug: 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.

    Other Name: Nexavar
  • 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.
    • Biological: Pexastimogene Devacirepvec (Pexa Vec)
    • Drug: Sorafenib
  • Active Comparator: Sorafenib
    Sorafenib (400 mg twice daily) begins on Day 1.
    Intervention: Drug: Sorafenib
