Australian GeneICE Patent Granted

For immediate release: 29th January 2008 VALIRX PLC ("ValiRx" or the "Company") Australian GeneICE Patent Granted ValiRx (AIM: VAL), the cancer therapeutics company, today announces that its proprietary gene-silencing technology, GeneICE, has received patent approval by the Australian Patent Office. This follows the granting of a US patent in April 2007 and a European patent in August 2007. ValiRx holds the rights to GeneICE through its subsidiary, Cronos Therapeutics Ltd ("Cronos"), which has an exclusive worldwide license agreement with Imperial College Innovations. GeneICE compounds have the potential to freeze the development and growth of cancerous cells and also have potential major applications in inflammatory disease and inherited genetic conditions. Cronos' partner, Cancer Research UK, a prestigious research institute in Europe, has recently completed phase one of its pre-clinical trials on GeneICE through Cancer Research Technology Limited ("CRT"). In these trials, GeneICE was successfully shown to trigger cell death in ovarian, pancreatic and prostate cancer cells and could potentially be relevant to other cancers. Dr Satu Vainikka, CEO of ValiRx, commented: "This latest patent further underpins the robustness of our gene silencing technology. Australia has one of the highest incidence rates for certain cancers in the world." --Ends-- About ValiRx plc ValiRx is a biopharmaceutical development company that is building a portfolio of complementary cancer-related therapeutic and diagnostic technologies.
