Item 5.04    Temporary Suspension of Trading Under Registrant's Employee Benefit Plans.

        OncoGenex Pharmaceuticals, Inc. (formerly Sonus Pharmaceuticals, Inc.) (the "Company") has decided to amend and restate the Sonus Pharmaceuticals, Inc. 401(k) Profit Sharing Plan and Trust (the "Plan") onto a plan document provided by Fidelity Investments, with Fidelity Investments serving as Trustee for the restated plan. The provisions of the restated Plan (which will be renamed) will be substantially the same as currently reflected in the Plan; provided, however, that different investment options will be available than those currently offered. Specifically, the Plan will not offer securities of the Company as an investment option.

        As a result of these changes, on December 18, 2008, pursuant to Section 306 of the Sarbanes-Oxley Act of 2002 and Section 104 of Regulation BTR of the Securities Exchange Act of 1934, as amended, the Company transmitted a notice to the Company's directors and executive officers regarding an impending blackout period. The blackout period is expected to commence on January 11, 2009 and is expected to end on March 8, 2009. The notice specified that, during the blackout period, participants in the Plan will be unable to access their accounts to direct or diversify their investments, or obtain a loan or distribution from the Plan. Additionally, the notice specified that the Company's directors and executive officers may not, during the blackout period, purchase, sell or otherwise acquire or transfer any of the Company's common stock or exercise any stock options of the Company.

        A copy of the aforementioned notice sent to directors and executive officers is attached hereto as Exhibit 99.1 and is incorporated herein by reference.

        Any questions concerning the blackout period should be addressed to Stephen Anderson, Chief Financial Officer, at the Company's headquarters, 1522 217th Place SE, Suite 100, Bothell, Washington, 98021 or by telephone at (604) 736-3678.
