The Lancet Publishes Vasogen's ACCLAIM Results

MISSISSAUGA, ON, Jan. 18 /PRNewswire-FirstCall/ - Vasogen Inc. (NASDAQ:VSGN; TSX:VAS) today announced that The Lancet, a world-leading medical journal, will publish an article entitled 'Results of a non-specific immunomodulation therapy in chronic heart failure (ACCLAIM trial): a placebo-controlled randomised trial' in its January 19th issue (Lancet 2008; 371: 228-36). The article describes the results from Vasogen's 2,400-patient ACCLAIM trial of its Celacade(TM) system in patients with chronic heart failure. Celacade is designed to target the destructive chronic inflammation underlying the development and progression of chronic heart failure.

The interpretation of the findings in The Lancet is that: "Non-specific immunomodulation (Celacade) may have a role as a potential treatment for a large segment of the heart failure population, which includes patients without a history of myocardial infarction (irrespective of their functional NYHA class) and patients within NYHA class II."

While the ACCLAIM study did not meet its primary endpoint for the intent-to treat-population, this primary endpoint was met for two large pre-specified subgroups of patients. In the trial, Celacade was shown to significantly reduce the risk of death or cardiovascular hospitalization by 39% in the subgroup of 689 patients with NYHA Class II heart failure, and by 26% in the subgroup of 919 patients with no prior history of heart attack. Importantly, the large risk reduction observed in these subgroups was achieved on top of the benefits derived from current standard-of-care medications and device therapy for heart failure.

"We are extremely pleased with the publication of the ACCLAIM results in The Lancet," commented Chris Waddick, President and CEO of Vasogen. "As previously reported, we expect that this publication will help to underpin our commercial activities with Celacade in the European Union, where it has already been approved, as well as the initiation of the ACCLAIM-II trial, our confirmatory trial in NYHA Class II patients being planned for the purpose of achieving regulatory approval in the United States."

The FDA has recommended that Vasogen use a Bayesian approach in the design of ACCLAIM-II, the Company's confirmatory trial. The Agency indicated that they were recommending this approach specifically because it would allow for the borrowing of statistical power from the ACCLAIM trial, and has the potential to substantially reduce the sample size required for a confirmatory study.

The planned trial design for ACCLAIM-II indicates that as few as 300 patients could provide sufficient data to confirm the NYHA Class II findings in the ACCLAIM trial, which demonstrated a 39% reduction (p=0.0003) in the risk of death or cardiovascular hospitalizations for patients receiving Celacade. Furthermore, the use of an adaptive clinical trial design also provides the flexibility to increase the sample size up to 600 patients, should additional data be required.

About Vasogen:

Vasogen is a biotechnology company engaged in the research and commercial development of therapies designed to target the destructive inflammatory process associated with the development and progression of cardiovascular and neurodegenerative disorders. The Company's lead product, the Celacade(TM) System, is designed to activate the immune response to apoptosis - an important physiological process that regulates inflammation. Celacade has received European regulatory approval under the CE Mark for chronic heart failure and is being marketed in the EU by Grupo Ferrer Internacional, S.A. Celacade is also in late-stage clinical development for the treatment of chronic heart failure in the United States. Vasogen is also developing a new class of drugs for the treatment of certain neuro-inflammatory disorders. VP025 is the lead candidate from this new class of drugs.
