    on its insulin program -

    TSX symbol: SBS

    CALGARY, June 26 /CNW/ - SemBioSys Genetics Inc. (TSX:SBS), a
biotechnology company developing a portfolio of therapeutic proteins for
metabolic and cardiovascular disease, today announced positive preclinical
data supporting the development of plant-derived recombinant human insulin.
The Company presented its findings at the 67th Scientific Sessions of the
American Diabetes Association (ADA) in Chicago. Specifically, the Company's
abstract and poster presentation highlighted its recent accomplishments in the
development of a highly-scalable, low-cost source of insulin, including:

    
    -  Results demonstrating that the Company exceeded its commercial target
       levels of insulin accumulation in safflower, its commercial plant
       system.
    -  Laboratory results demonstrating that safflower-produced insulin is
       physically, structurally and physiologically indistinguishable from
       pharmaceutical-grade human recombinant insulin.
    -  Laboratory results from competitive receptor binding assays
       demonstrating the functional equivalence of the Company's
       safflower-produced insulin to insulin reference standard.
    -  Animal results from insulin tolerance test assays demonstrating the
       pharmacodynamic equivalence of safflower-derived insulin to
       pharmaceutical-grade insulin.
    

    "These results validate the feasibility of our plant production
technology for the large-scale manufacture of human insulin. Plants are a
transformative platform for the production of biopharmaceuticals. They are
ideally suited to large volume products such as human insulin, where capacity
is in short supply. Plants offer unprecedented capacity and flexibility for
low-cost biopharmaceutical manufacturing and provide by far the most
attractive economics, both in terms of capital and cost of goods," said Andrew
Baum, President and CEO of SemBioSys Genetics Inc. "We have confirmed our
intention to pursue an abbreviated clinical trial under the 505(b)(2) rules of
the Food and Drug Act after a meeting with the U.S. Food and Drug
Administration late last year. We expect to enter directly into a Phase II
trial in early 2008 with commercialization of safflower-produced insulin
scheduled for as early as 2010."
    During the Scientific Sessions on Sunday June 24th, Dr. Larry C. Deeb,
ADA President, Medicine and Science, highlighted the need for increased access
to insulin and insulin treatment as part of his presidential address. Dr. Deeb
described the dire situation facing those suffering from type 1 diabetes in
parts of Africa where the cost of insulin is a primary barrier to treatment.
    Insulin is the largest volume recombinant biopharmaceutical product on
the market today with production estimated at approximately 6,000 kilograms in
2006 and sales in excess of US$7.5 billion worldwide. SemBioSys estimates that
the demand for insulin will increase to nearly 16,000 kilograms in 2012;
fuelled by an increasing incidence of diabetes, increasing demand for access
to insulin treatment in the developing world and adoption of alternate insulin
delivery technologies, which require between 5 to 20 times more insulin than
injection methods, in the developed world.
    The scientific poster and abstract SemBioSys presented at the ADA were
entitled: "Chemical and Biological Characterization of Recombinant Human
Insulin Produced in Transgenic Plants." Abstract Number 0459-P by Joseph
Boothe and colleagues at SemBioSys.
