Vasogen Files Amended And Restated Prospectus

MISSISSAUGA, ON, Aug. 11 /PRNewswire-FirstCall/ - Vasogen Inc. , today announced that it has filed an amended and restated prospectus with the Ontario Securities Commission and the U.S. Securities and Exchange Commission (SEC) to increase by 30 million the number of common shares that may be sold by certain selling shareholders under the prospectus. The common shares may be issued in connection with the senior convertible notes issued in October 2005 by Vasogen Ireland Limited (VIL), a wholly owned subsidiary of Vasogen Inc. As of August 1, 2006, the outstanding principal amount owing under the notes was US$14.8 million. VIL may continue to repay the outstanding principal on a monthly basis over the remaining term of the notes in any combination of cash or common shares at its sole discretion, provided certain conditions are met. Given VIL’s right to pay in cash and the potential fluctuation of the Company’s share price, the number of shares actually issued may be significantly different from the number covered by the amended prospectus.

In addition, Vasogen Inc. has today filed with applicable Canadian securities regulatory authorities on SEDAR its Report on Form 40-F previously filed with the SEC on EDGAR on February 21, 2006.

About Vasogen:

Vasogen is focused on the research and commercial development of technologies targeting the chronic inflammation underlying cardiovascular and neurological disease. The recently completed international 2,400-patient ACCLAIM trial assessed the impact of the Celacade technology on reducing the risk of mortality and morbidity in patients with advanced heart failure. Full results for the ACCLAIM study are scheduled to be presented at the World Congress of Cardiology 2006, being held in Barcelona, Spain, from September 2 to 6 and at the 10th Annual Scientific Meeting of the Heart Failure Society of America being held in Seattle, Washington, from September 10 to 13, 2006. Vasogen is also developing a new class of drugs for the treatment of neuro-inflammatory and neuro-vascular disorders. VP025, which is entering phase II clinical development, is the lead product candidate from this new class of drugs.
