简要总结
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.
详细描述
This is a Phase 2, open-label, pilot safety study designed to evaluate the safety and tolerability of sequential therapy consisting of Pexa-Vec (JX-594) followed by standard sorafenib in patients with advanced, unresectable primary hepatocellular carcinoma (HCC).
Patients will receive an initial intravenous (IV) infusion of Pexa-Vec at a dose of 1 x 10^9 plaque-forming units (pfu) on Day 1. This is followed by two intratumoral (IT) injections of Pexa-Vec on Day 8 and Day 22, each at a total dose of 1 x 10^9 pfu divided among 1 to 5 hepatic tumors. Starting on Day 25 (approximately 3 days after the final regular dose of Pexa-Vec), patients will initiate standard oral sorafenib therapy twice daily. For patients with viable hepatic tumor tissue at Week 12, an optional additional IT dose of Pexa-Vec may be administered.
The primary objective of this study is to assess the safety and toxicity of this sequential regimen, determined by the incidence of treatment-related Grade 3 and Grade 4 adverse events (AEs) and treatment-related serious adverse events (SAEs). Secondary objectives include evaluating the disease control rate (DCR) at 12 weeks, overall survival (OS) time, and radiographic response rate based on modified RECIST (mRECIST 1.0) and/or Choi criteria.

研究组 & 干预措施
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.

结局指标
主要结局
Determine safety and tolerability of intravenous infusion of JX-594 followed by intratumoral injections with JX-594 prior to standard sorafenib therapy
时间窗: Safety evaluations through 28 days after last dose of JX-594
Adverse events will be collected and assessed to assess safety and tolerability through 28 days after last dose of JX-594 (or until all events considered probably or possibly related to JX-594 have resolved, stabilized, or returned to baseline status).
次要结局
- Determine Disease Control Rate (DCR) at 12 weeks(Disease control and response assessment at 12 weeks from first JX-594 dose)
- Determine overall survival time(Ongoing (average of 1 year))
- Determine radiographic response rate(Periodically throughout study participation (average of up to 1 year))
