BioMS Medical initiates enrollment in pivotal U.S. phase III multiple sclerosis trial

    Toronto Stock Exchange Symbol: MS

    EDMONTON, June 5 /CNW/ - BioMS Medical Corp (TSX: MS), a leading
developer of products for the treatment of multiple sclerosis (MS), today
announced that the first patients have been enrolled in MAESTRO-03, its U.S.
pivotal phase III clinical trial of MBP8298, a proprietary synthetic peptide
for the treatment of multiple sclerosis. The randomized, double-blind study is
enrolling approximately 510 secondary progressive MS patients at approximately
60 sites across the U.S. who will be administered either MBP8298 or placebo
intravenously every six months for a period of two years.
    "This is an important milestone in our strategy to commercialize MBP8298
on a global basis," said Kevin Giese, President and CEO of BioMS Medical. "The
U.S. represents nearly half of the MS market and a successful outcome to this
trial would put BioMS in a strong position to capture a significant portion of
this and other major MS markets."
    The primary clinical endpoint for the MAESTRO-03 trial is defined as a
statistically significant time to disease progression as measured by the
Expanded Disability Status Scale (EDSS), in patients with HLA-DR2 and/or
HLA-DR4 immune response genes. Up to 75% of all MS patients are HLA-DR2 and/or
HLA-DR4 positive.

    MBP8298 is being assessed in two additional ongoing trials:

    -   MAESTRO-01 is a pivotal phase III trial being conducted in Canada and
        Western Europe evaluating MBP8298 for the treatment of secondary
        progressive multiple sclerosis (SPMS). The trial is a randomized,
        double-blind study and is fully recruited with 611 patients.
    -   MINDSET-01 is a phase II trial evaluating MBP8298 for the treatment
        of relapsing-remitting multiple sclerosis (RRMS). The trial is a
        randomized, double-blind study and is fully recruited with
        approximately 215 patients.

    About MBP8298 - Novel Mechanism of Action

    In MS patients, the body's immune system inappropriately attacks the
myelin coating around the nerves in the brain and spinal column, whereas
healthy people are otherwise "tolerant" of such common body components. The
proposed mechanism of action of MBP8298 is, by design, to re-introduce such a
state of "tolerance" to a critical portion of the nerve's Myelin Basic Protein
that is an immunological site of attack in many MS patients. This is
accomplished by the I.V. injection of MBP8298 every six months.
    Phase II and long-term follow-up treatment of MS patients with MBP8298,
recently published in the European Journal of Neurology showed that MBP8298
safely delayed the median time to disease progression for five years in
progressive MS patients with HLA-DR2 or HLA-DR4 immune response genes.

    About Multiple Sclerosis

    Multiple sclerosis (MS) is thought to affect as many as 2.5 million
people worldwide, including approximately 75,000 in Canada, 400,000 in the
United States and more than 450,000 in Western Europe. MS is a progressive
disease of the central nervous system, characterized initially by episodes of
paralysis, blindness, sensory disturbances and cognitive impairment. Almost
half of all MS patients have the secondary progressive form of the disease.
