NCT ID: NCT01171651

Last Updated: 2016-01-20

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE2
• Total Enrollment: 25 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2009-08-31
• Study Completion Date: 2015-12-31

Brief Summary

The purpose of this pilot safety study is to evaluate the safety and tolerability of JX-594 (Pexa-Vec) administered intravenously and intratumorally prior to standard sorafenib therapy.

Conditions

Carcinoma, Hepatocellular

Study Design

• Allocation Method: NON_RANDOMIZED
• Intervention Model: SINGLE_GROUP
• Primary Study Purpose: TREATMENT
• Blinding Strategy: NONE

Study Groups

JX-594 followed by sorafenib

1e9 pfu (plaque-forming units) total JX-594 dose on each of up to four (4) JX-594 treatment days. Sorafenib is initiated after 3 JX-594 treatments and briefly interrupted if an optional 4th JX-594 treatment is given.

Group Type: EXPERIMENTAL

JX-594 followed by sorafenib

Intervention Type: DRUG

Patients will receive a total dose of 1e9 per treatment starting with one IV dose on Day 1 and injected intratumorally in 1-5 intrahepatic tumors on Day 8 and 22. Starting on Day 25 (3 days after the final JX-594 dose) patients will initiate oral sorafenib therapy twice daily according to standard approved guidelines. An optional maintenance JX-594 dose may be given intratumorally at Week 12 (sorafenib briefly interrupted).

Eligibility Criteria

Inclusion Criteria

• Histological confirmation or clinical/laboratory diagnosis of primary hepatocellular carcinoma (HCC)
• Cancer is not surgically resectable for cure

Exclusion Criteria

• Known contraindications to sorafenib

• Patients with household contacts who meet any of these criteria unless alternate living arrangements can be made during the patient's active dosing period and for 7 days following the last dose of study medication:
• Pregnant or nursing an infant
• Children < 12 months old
• History of exfoliative skin condition that at some stage has required systemic therapy
• Significant immunodeficiency due to underlying illness (e.g. HIV/AIDS) and/or medication
