The Lancet Publishes Vasogen's ACCLAIM Results



    MISSISSAUGA, ON, Jan. 18 /CNW/ - 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.

ongoing analysis of the ACCLAIM trial results, the requirement or election to
conduct additional clinical trials and the size and design of any such trials,
delays or setbacks in the regulatory approval process, difficulties in the
maintenance of existing regulatory approvals, securing and maintaining
corporate alliances, the need for additional capital and the effect of capital
market conditions and other factors on capital availability, the potential
dilutive effects of any financing, risks associated with the outcomes of our
preclinical and clinical research and development programs, the adequacy,
timing, and results of our clinical trials, competition, market acceptance of
our products, the availability of government and insurance reimbursements for
our products, the strength of intellectual property, reliance on partners,
