SAN FRANCISCO and ILLKIRCH, France, April 6, 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, and Transgene (NYSE Euronext Paris: FR0005175080), a bio-pharmaceutical company specialized in the development of immunotherapeutic products, reported interim results from Phase 1 dose-escalation clinical trials demonstrating that administration of JX-594 targets tumor vasculature. By directly targeting and replicating within tumor vasculature, JX-594 disrupts the blood supply to the solid tumors contributing to destruction of the cancer. Data were reported in a poster presentation at the 102nd Annual Meeting of the American Association for Cancer Research (AACR) in Orlando, Florida.
"In addition to targeting, infecting and destroying cancer cells and stimulating a targeted immune response against remaining cancer cells, the analysis presented at AACR demonstrates JX-594's critical third mechanism of action—the disruption of the blood supply to the tumor," said David H. Kirn, M.D., president and chief executive officer of Jennerex.
"Importantly, these data show that both intravenous and intratumoral injection of JX-594 can effectively attack tumor vasculature. These results further demonstrate that JX-594 may have therapeutic benefit for a variety of solid tumors including liver, colorectal and other cancers," added Philippe Archinard, chairman and chief executive officer of Transgene.
Twenty three patients were enrolled in the Phase 1 dose-escalation clinical study using intravenous JX-594 to treat advanced, treatment refractory solid tumors. Tumor biopsies, evaluated through immunohistochemical analysis, showed that JX-594 given intravenously infected the vasculature of tumors causing the blood supply to the tumor to be disrupted. In addition, in another trial of patients with primary liver can
