| FDA Approval To Begin Clinical Trials Of Anti-Cancer Drug GTI 2040
 
 Lorus Therapeutics Inc. ("Lorus") announced that the U.S. Food and Drug Administration ("FDA") has approved the
 Company's Investigational New Drug ("IND") application to begin clinical trials of the anti-cancer drug, GTI 2040. The clinical
 trial will take place under the direction of Dr. Richard Schilsky of the Chicago Cancer Research Center.
 
 "The primary goal of this Phase I/II clinical trial is to look at the safety of GTI 2040 in patients with a variety of tumors," said
 Mr. Philippe G. Lacaille, chairman and chief executive officer at Lorus. "The clinical trial of GTI 2040 is the first involving our
 antisense compounds and we are very pleased to be starting it so quickly after our recent acquisition of GeneSense
 Technologies. The trial will be a dose escalating study to determine optimum dosing levels and will involve approximately 20 to
 25 patients who are non-responsive to other therapies."
 
 Although the primary goal of the clinical trial is to evaluate safety, tests aimed at monitoring potential efficacy of GTI 2040 will
 also be performed.
 
 In an earlier announcement, Lorus reported that GTI 2040 had demonstrated excellent anti-tumor activity in in vivo models
 when tested against a wide variety of human tumors.
 
 "Depending on the tumor model, we saw significant inhibition of tumor growth, disease stabilization and in some cases, dramatic
 tumor regression," said Dr. Jim Wright, president and chief scientific officer at Lorus. "GTI 2040 was tested extensively for
 safety in several animal models, and we expect to find similar safety characteristics in our clinical trials."
