Protocol Summary

Protocol No.: OCR14527

Sponsor Protocol No.: JX594-HEP024

Study Title
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

Principal Investigator(s)
Cabrera, Roniel

Objective
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.

Phase: Phase III

Age Group: Adult

Scope: National

Treatment
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.
