Viral Therapy in Treating Patient With Liver Cancer


Phoenix/Scottsdale, Ariz.

Trial status:
Open for Enrollment
Why is this study being done?


     I. To determine the maximum tolerated dose (MTD) of vesicular stomatitis virus (VSV)-interferon beta (IFN-β) (recombinant vesicular stomatitis virus expressing interferon beta) in patients with hepatocellular carcinoma (HCC) refractory or intolerant to sorafenib therapy.


     I. To estimate the tumor response rate and overall survival.


     I. To determine the pharmacokinetic (PK) profile of VSV-IFN-β in patients with HCC by measurement of VSV-IFN-β in blood by reverse transcriptase polymerase chain reaction (RT-PCR).

     II. To characterize the pharmacodynamics (PD) of VSV-IFN-β by way of measuring serum interferon-β and also VSV-RT-PCR of VSV-IFN-β listed above.

     III. Assess CD8+ T cell (both general and VSV-hIFN-β specific) and natural killer (NK) cell responses.

     IV. Assess status of human interferon beta pathway pre/post therapy in tumor/normal liver tissue (status of IFN-β, interferon stimulated gene factor 3 [ISGF3 complex constituting signal transducer and activator of transcription (STAT)1/2 and p48 (ISGF3 γ)]).

     V. Assess phosphorylation of STAT1/2 post-therapy. VI. Evaluate transcription of interferon mediated genes (protein kinase R, the death receptor-tumor necrosis factor [TNF]-related apoptosis-inducing ligand [TRAIL], 2'-5' oligoadenylate/ribonucleic acid [RNA]se L proteins, heat shock proteins [Hsp 60/70/90], major histocompatibility class antigens and interferon regulatory factor [IRF]-7).

     VII. Assess presence of VSV in tumor/normal liver subsequent to administration of VSV-human IFN-β (hIFN- β).

     OUTLINE: This is a dose-escalation study.

     Patients receive recombinant vesicular stomatitis virus expressing interferon beta intratumorally on day 1.

     After completion of study treatment, patients are followed up every 4 weeks for up to 3 years.
