LORUS ANNOUNCES SUCCESSFUL DSMB REVIEW AND PHARMACOKINETIC RESULTS FROM THE ONGOING VIRULIZIN(R) PHASE III CLINICAL TRIAL
TSX:
LOR
AMEX: LRP
TORONTO, CANADA, February 8, 2005 - -Lorus Therapeutics Inc. ('Lorus'), a biopharmaceutical company specializing in the research, development and commercialization of pharmaceutical products and technologies for the management of cancer, announced today that an independent data safety monitoring board (DSMB) reported on January 31, 2005 that the Company's ongoing phase III registration clinical trial in advanced pancreatic cancer, for its lead anticancer drug Virulizin(R), can continue without modification to the phase III study design.
The DSMB arrived at its independent conclusion after reviewing preliminary data from the phase III clinical trial. The principal objective of the DSMB review was to evaluate the interim safety of the study. The Virulizin(R) phase III clinical trial completed full enrollment of 436 patients at over 100 clinical sites in North America, South America and Europe in mid 2004 and is expected to conclude in mid 2005. The DSMB is an independent panel of research experts who are not participating in the study. The primary responsibility of the DSMB is to oversee the study and ensure the well being and safety of the participants in this clinical trial.
Additionally, Lorus has learned that the results of the pharmacokinetic drug interaction portion of the phase III clinical trial revealed no significantadverse interactions between Lorus's product Virulizin(R) and the current standard of care in pancreatic cancer, gemcitabine. This data was also reviewed by an independent body and submitted to the U.S. Food and Drug Administration (FDA). Virulizin(R) has been granted fast track status, orphan drug status and a special protocol assessment by the FDA in advanced pancreatic cancer.

"The favorable safety profile of Virulizin(R), along with the positive outcome of the PK portion of our ongoing phase III clinical trial is very important as we prepare for the conclusion, data analysis and planned New Drug Application (NDA) for this important registration study in pancreatic cancer," said Lorus' CEO Dr. Jim Wright.
Virulizin(R) is a novel immunotherapy that stimulates a patient's innate immune system through the activation of macrophages and the infiltration of NK cells into tumors. Evidence of clinical response was observed in Phase II clinical studies of Virulizin(R) as a monotherapy in advanced pancreatic cancer. Median survival in these Phase II studies compared favorably with single-agent chemotherapy trials, and in contrast to most standard chemotherapeutic drugs, Virulizin(R) was well tolerated.
