First North American Patient in Liver Cancer Clinical Trial Treated at UT Medical Center

findeissThe University of Tennessee Medical Center initiated treatment on North America’s first participant in a clinical trial for patients who have advanced liver cancer and limited available treatment options. The Phase III clinical trial involves the injection of an experimental agent directly into liver tumors. The agent is a vaccinia virus (Pexa-Vec), modified to destroy cancer cells and create an immune response to the cancer (also known as “Oncolytic Immunotherapy”). This final phase study will assess the effectiveness of the agent, combined with standard chemotherapy, in fighting the cancerous tumors and improving survival.

The clinical trial, known as the PHOCUS trial, is for patients with hepatocellular carcinoma (HCC) who have failed localized therapies and have not undergone prior systemic treatment. Half of the PHOCUS trial participants will receive sorafenib (Nexavar®), the only drug currently approved for HCC treatment, while the other half will receive injections of Pexa-Vec, an oncolytic vaccinia virus immunotherapy created by SillaJen, Inc., followed by sorafenib.

"Having been involved in a prior clinical trial using Pexa-Vec, I remain excited about the potential this new cancer immunotherapy holds," said Laura Findeiss, MD, Professor and Chair of the Department of Radiology and principal investigator of the study at The University of Tennessee Medical Center and UT Graduate School of Medicine. "At The University of Tennessee Medical Center, we are at the forefront of bringing innovative cancer treatments to patients, as exemplified by having enrolled the first North American patient into the PHOCUS trial."

The randomized study is designed to enroll 600 patients and will be conducted at approximately 140 sites worldwide. The primary objective of the study will be to determine the overall survival of patients treated with Pexa-Vec, followed by sorafenib versus sorafenib alone. Secondary objectives will include safety as well as assessments for tumor responses between the two groups as measured by the following endpoints: time to progression, progression-free survival, overall response rate and disease control rate.

"Primary liver cancer remains an unmet medical need for thousands of newly diagnosed patients and their families," said Eun Sang Moon, chief executive officer of SillaJen. "We hope that the initiation of the global PHOCUS clinical trial is an early step toward developing a new treatment for this disease."
