OncoGenex Announces Departure of Chief Financial Officer

BOTHELL, WA and VANCOUVER, BC, Feb. 25 /PRNewswire-FirstCall/ - OncoGenex Pharmaceuticals, Inc. (NASDAQ: OGXI) announced today that the Company and Steve Anderson, its chief financial officer, have agreed that he will leave the Company effective yesterday.

OncoGenex has initiated an executive search to identify a CFO candidate suited for the next stage of company growth, with deep ties in the biopharma investment community and experience transitioning a pharmaceutical company from R&D stage to commercial development.

"I want to thank Steve Anderson for his excellent service during the past four years as chief financial officer at OncoGenex, during which time OncoGenex successfully completed a reverse takeover of Sonus Pharmaceuticals, became a Nasdaq-listed public company and licensed its lead drug candidate to Teva Pharmaceutical," said Scott Cormack, President and Chief Executive Officer of OncoGenex. "In recognition of the company moving to a new stage in its development, Steve will be moving on to new challenges. We wish him every success in his future endeavors. While we identify a candidate to fit the evolving responsibilities of the job position, we have a strong financial team already in place to continue accurate, timely and seamless accounting and reporting."

"Our business remains focused on the clinical development of our drug candidates led by our Chief Medical Officer Dr. Cindy Jacobs," added Cormack. "Dr. Jacobs maintains an active role on the OGX-011 Joint Steering Committee in partnership with Teva Pharmaceutical, which is currently preparing to initiate two Phase 3 clinical trials in prostate cancer this year. In addition, Dr. Jacobs' team has been critically involved in advancing the OGX-427 program, including development of recent clinical trial protocols for Phase 2 prostate and bladder cancer."
