TORONTO, CANADA, July 6, 2005 – Lorus Therapeutics, a biopharmaceutical company specializing in the development and commercialization of pharmaceutical products and technologies for the management of cancer today announced the successful completion of Last Patient Visit (LPV) in the Global Phase III clinical study of Virulizin(R) in combination with Gemzar(R) for the treatment of pancreatic cancer.  This Phase III clinical registration study has been ongoing since early 2002.  The study has enrolled 436 patients at over 100 clinical sites in North America and Europe.


This phase III clinical study compares the efficacy and safety of Virulizin(R) when combined with Gemzar(R) versus a placebo combined with Gemzar(R) in patients with locally advanced or metastatic pancreatic cancer.  The primary efficacy endpoint is overall survival, while secondary endpoints include progression of symptoms of pain, deterioration of performance status and weight loss.  


Virulizin(R) has been granted fast track status, orphan drug status in the United States and Europe and a Special Protocol Assessment (SPA) by the U.S. Food and Drug Administration (FDA) in advanced pancreatic cancer.  Additionally, the US FDA agreed in May to a rolling New Drug Application (NDA) for Virulizin(R).

LPV will be followed by database lock later this summer once the data cleaning exercise has been completed at all the participating clinical sites.  According to the study protocol requirements for follow-up, database lock and data analysis, the results of the study are anticipated for late 2005.  This clinical study report will be pivotal in the application for marketing approval for Virulizin(R), which is planned for submission to the FDA in the first half of 2006.


“Approximately one year ago, we met the challenging milestone of ‘Enrollment Close” with this study and as we move forward, particularly in light of the successful completion of the ‘Last Patient Visit’, we continue to strengthen our ability to submit a comprehensive clinical package to the FDA,” said Dr. Jim Wright CEO of Lorus.  “We look forward to this exciting time ahead of us at Lorus.”
