AASLD-Jennerex to Present Final Survival Data From Randomized Phase 2 Clinical Trial of JX-594 in Advanced Liver Cancer

SAN FRANCISCO, Nov. 2, 2011 /PRNewswire/ -- Jennerex, Inc., a private clinical-stage biotherapeutics company focused on the development and commercialization of first-in-class targeted oncolytic products for cancer, today announced that final data from its Phase 2 randomized clinical trial in advanced liver cancer patients will be presented on Monday, November 7, 2011 at the 62nd Annual Meeting of the American Association for the Study of Liver Diseases (AASLD) taking place November 4-8, 2011 in San Francisco, California. These data, evaluating multi-dose administration of JX-594 in U.S., Korean and Canadian patients with advanced liver cancer, were selected for an oral presentation in the late-breaking oral session of the conference.

The presentation details are as follows:

Abstract Title: "A Randomized, Controlled Phase 2 Clinical Trial of JX-594, a Targeted Multi-Mechanistic Oncolytic Poxvirus, in Patients with Advanced Hepatocellular Carcinoma: Final Data." (Abstract #LB1)
Presenter: Tony Reid, M.D., Ph.D., professor of medicine, hematology/oncology, director of clinical investigation, and the tumor growth, invasion and metastasis program, Moores UCSD Cancer Center at the University of California, San Diego
Session: Late-Breaking Oral Session, November 7, 2011, 2:45 p.m. PT

JX-594: A Multi-Mechanistic Approach To Targeting Cancer

JX-594 is a proprietary, engineered oncolytic virus that is designed to selectively target and destroy cancer cells. JX-594 is designed to attack cancer through three diverse mechanisms of action: 1) the lysis of cancer cells through viral replication, 2) the shutdown of the blood supply to tumors through vascular targeting and destruction, and 3) the stimulation of the body's immune response against cancer cells, i.e., active immunotherapy. Phase 1 and Phase 2 clinical trials in multiple cancer types to date have shown that JX-594, delivered either directly into tumors or systemically, induces tumor shrinkage and/or necrosis and is well-tolerated by patients (over 120 treated to date).

JX-594 is the most advanced product candidate from Jennerex's proprietary SOLVE™ (Selective Oncolytic Vaccinia Engineering) platform. SOLVE takes advantage of the natural attributes of poxviruses as well as their ability to be genetically engineered to produce safe, therapeutic viruses that can infect solid tumors both systemically and locally. The vaccinia poxvirus strain backbone of JX-594 has been used safely in millions of people as part of a worldwide vaccination program. This strain naturally targets cancer cells due to common genetic defects in cancer cells. JX-594 was engineered to enhance this natural safety and cancer-selectivity by deleting its thymidine kinase (TK) gene, thus making it dependent on the cellular TK expressed at persistently high levels in cancer cells. To enhance product efficacy, JX-594 is also engineered to express the immunogenic GM-CSF protein. GM-CSF complements the cancer cell lysis of the product candidate, leading to a cascade of events resulting in tumor necrosis, tumor vasculature shutdown and sustained anti-tumoral immune attack.
