Hepatocellular Carcinoma Study Comparing Vaccinia Virus Based Immunotherapy Plus Sorafenib vs Sorafenib Alone

Not Recruiting

Trial ID: NCT02562755


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.

Official 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
