TORONTO, CANADA – April 8, 2005 – Lorus Therapeutics Inc. (“Lorus”) today reported financial results for the three and nine-month periods ended February 28, 2005. Unless specified otherwise, all amounts are in Canadian dollars.

“Our third quarter results demonstrate, as promised, a significant reduction in our burn rate, year over year, as our Virulizin^® fully enrolled global clinical trial continues to wind down. We have also maintained our strong cash position through closing the second $5 million tranche of the convertible debenture agreement” said Dr. Jim Wright, president and CEO. “The results from the DSMB review, which confirmed our knowledge regarding the safety profile of Virulizin^® as well as the discoveries related to IL-17E have helped to further solidify our confidence in the future success of Virulizin^®.”

Cash used in operating activities before net change in non-cash working capital decreased 46% to $4.1 million for the three months ended February 28, 2005 compared to $7.6 million in the prior year. For the nine-month period ended February 28, 2005 cash used in operating activities before net change in non-cash working capital totaled $14.2 million compared with $20.8 million in the prior year. The significant decrease in our cash burn rate is due to lower research and development expenditures as our Phase III clinical trial of Virulizin^® winds down.

Loss for the period for the three months ended February 28, 2005 decreased 35% to $5.3 million ($0.03 per share) compared to a loss of $8.2 million ($0.05 per share) for the same period last year. For the nine month period ended February 28, 2005, loss for the period totaled $17.5 million ($0.10 per share) compared to $22.3 million ($0.13 per share) for the comparable period last year representing a year to date reduction in net loss of 22%. The year to date decrease in loss is due primarily to a reduction of $8.1 million in research and development expenses offset by lower revenues and interest income of $600,000 and $608,000 respectively, and non cash charges for the recognition of stock-based compensation expense in fiscal 2005 of $1.2 million resulting from the adoption of Canadian Institute of Chartered Accountants Handbook Section 3870, ‘Stock-Based Compensation and Other Stock-Based Payments’ effective June 1, 2004.

Revenue has decreased to $6,000 for the nine months ended February 28, 2005 compared with $606,000 for the same period in 2004. The decrease is primarily due to a $546,000 license fee received in the prior year related to the out-licensing of our clotrimazole analog library to Cyclacel Ltd.

Research and development expenses for the three months ended February 28, 2005 decreased to $3.2 million compared to $7.3 million for the same period last year, representing a 56% decrease over the prior year. For the nine months ended February 28, 2005, research and development expenses decreased 40% to $12.1 million compared to $20.2 million for the same period last year. The decrease in research and development activities relates primarily to lower clinical trial costs for the fully enrolled Phase III trial of Virulizin^® in comparison to the prior year as startup costs have been incurred and the clinical trial is winding down. Secondly, the initial costs of supplying the GTI-2040 drug to the NCI for the NCI sponsored phase II clinical trial program were incurred in 2004, for which Lorus continues to have a sufficient supply on hand for the clinical studies underway.

General & administrative expenses for the three months ended February 28, 2005 increased to $1.5 million compared to $1.0 million in the prior year. General and administrative expenses for the nine month period ended February 28, 2005 were $3.8 million compared with $3.4 million in the prior year. The increase is due to additions to the management team as well as higher consulting and legal costs.

Stock-based compensation expense of $341,000 for the three months ended February 28, 2005 and $1.2 million for the nine month period ended February 28, 2005 represents the amortization of the estimated fair value of stock options granted since June 1, 2002 applicable to the current service period as well as a one time charge of $207,000 recorded in the second quarter of 2005 representing the increase in value attributed to the November 18, 2004 shareholder approved amendment to the stock option plan to extend the contractual life of all options outstanding from five years to ten years.

Lorus recognized non-cash interest expense of $96,000 for the three months ended February 28, 2005 and $135,000 for the nine-month period ended February 28, 2005, representing interest at a rate of prime +1% on the first two tranches of the convertible debenture of $5 million each received on October 6, 2004 and January 14, 2005. The interest accrued on the debenture during the quarter was paid in common shares of the Company.

Accretion in the carrying value of the convertible debenture amounted to $137,000 for the three months ended February 28, 2005 and $195,000 for the nine-month period ended February 28, 2005. These amounts reflect the accretion charge from the date of issue (October 6, 2004) to the end of the quarter. This accretion charge arises as under Canadian GAAP, the Company has allocated the proceeds of the convertible debenture to the debt and equity instruments issued on a relative fair value basis resulting in the value of the $10.0 million convertible debenture having a carrying value of $6.5 million at inception. Each reporting period, the Company is required to accrete the carrying value of the convertible debenture such that at maturity on October 6, 2009, the carrying value of the debenture will be its face value of $10.0 million. The issued debentures are convertible into common shares of Lorus at $1.00 per share.

Interest income for the three months ended February 28, 2005 was $116,000, compared with $298,000 for the same period in the prior year. For the nine-month period, interest income was $397,000 in fiscal 2005 compared to $1.0 million for the same period last year. The decreases are attributable to a lower cash and short-term investment balance throughout fiscal 2005.

At February 28, 2005 Lorus had cash and cash equivalents and short-term investments totaling $20.3 million compared to $26.7 million at May 31, 2004. Working capital was $16.9 million at February 28, 2005 compared to $22.6 million at May 31, 2004. Pursuant to the $15 million convertible debenture agreement, Lorus expects to receive the remaining $5 million on April 15, 2005.
