          LORUS THERAPEUTICS SUPPORTS PANCREATIC CANCER AWARENESS MONTH

          -Update of Virulizin(R) compassionate use program announced-


TSX:     LOR
OTC BB:  LORFF

TORONTO, CANADA, NOVEMBER 7, 2003 - Lorus Therapeutics Inc. ("Lorus") announced
today the further global expansion of the compassionate use program for
Virulizin(R), its lead Phase III clinical drug for advanced pancreatic cancer.
The program has grown to include a total of 10 countries, with over 60 patients
having received Virulizin(R)for treatment of advanced pancreatic cancer in the
past year. Countries that have granted regulatory authorization for use of
Virulizin(R) as a compassionate drug now include the US, Canada, Japan,
Australia, Italy, Israel, Greece, Cyprus, Korea, and Taiwan.

"We are pleased to be able to support pancreatic cancer patients and health-care
providers worldwide in their efforts to seek newer, less toxic treatments. The
requests we receive through our program from patients and physicians in
countries around the globe attests to the dire need for new treatments," said
Dr. Jim Wright, CEO of Lorus. "We see a large demand for supply of this drug,
and our staff are committed to making as much supply as possible available to
compassionate use patients."

Since re-launching the compassionate use program in 2002, Lorus has provided
Virulizin(R) to patients primarily following failure of mainstay therapy, or in
the first-line setting where less toxic therapeutic alternatives were required.
Compassionate use data is being collected by Lorus and will be included as part
of the safety and use database for regulatory dossier filings. Compassionate use
programs are available in many countries to enable patients, following health
authority authorization, to receive investigational drugs or foreign-approved
drugs for the treatment of serious illnesses where no suitable alternative
treatment exists.

In addition, the company also announced as part of its commitment to Pancreatic
Cancer Awareness Month, its participation in the Weekend of Hope: Pancreatic
Cancer Symposium being held on November 7-9, 2003 in California. This
patient-based symposium is presented by the Pancreatic Cancer Action Network
(PanCAN), a national non-profit, patient advocacy organization that serves the
pancreatic cancer community.

"PanCAN is an important patient-oriented organization dedicated to helping
pancreatic cancer patients," added Dr. Wright. "We support its initiatives to
educate people about pancreatic cancer, as we evaluate Virulizin(R), in a Phase
III clinical trial for advanced pancreatic cancer at over 100 oncology centres
worldwide."

About Virulizin(R)
Virulizin(R) is currently in a global Phase III clinical trial for advanced
pancreatic cancer at major oncology centers in the US, Canada, Eastern and
Central Europe, and Latin America. The Phase III clinical study examines the use
of Virulizin(R) in the first-line treatment setting, in combination with
gemcitabine, the current chemotherapeutic standard of care for advanced
pancreatic cancer. Virulizin(R) is an immunotherapeutic drug that has been shown
to be well-tolerated in clinical trials. The drug has also demonstrated a broad
range of anti-tumor efficacy in pre-clinical testing. Virulizin(R) is currently
marketed in Mexico for malignant melanoma under a distribution agreement with
Mayne Pharma.
