SemBioSys' Plant-Produced Insulin Chemically and Physiologically Equivalent to Commercial Insulin in Animal Studies

    Calgary, Alberta (ots/PRNewswire) -

    - Canadian Biotechnology Company Takes Next Significant Step Towards  Advancing its Product to the Clinic -

    SemBioSys Genetics Inc. (TSX:SBS), a biotechnology company developing a  broad pipeline of protein-based pharmaceuticals and non-pharmaceutical  products, today announced that its proprietary plant-produced insulin has  been demonstrated in animal models to be chemically, structurally and  functionally equivalent to U.S. pharma grade human insulin. The results of  analytical, in vitro and in vivo assays confirm that insulin produced in  safflower, SemBioSys' commercial crop, is indistinguishable from human  insulin analytically and physiologically.

    "Establishing insulin equivalence is the second major scientific milestone from our insulin program in the past six months. By exceeding our  commercial target levels of human insulin accumulation in safflower last  July and now confirming that safflower-produced insulin is physiologically  equivalent to human insulin we believe we have substantially lowered the  scientific risk of our insulin program," said Andrew Baum, President and  CEO. "As a result of these achievements we expect that we will be able to  submit an Investigational New Drug Application (IND) later this year and initiate a Pharmacokinetic/Pharmacodynamic study of safflower-produced  insulin late in the fourth quarter of 2007 or early in the first quarter of  2008, leading to an end of Phase II meeting with the FDA in 2008."

    SemBioSys has confirmed the equivalence of safflower-produced insulin  through analytical, in vitro, and in vivo animal assays. Chemical and  structural authenticity have been confirmed through mass spectrometry and  peptide fingerprint analysis. Functionality of safflower-produced insulin  has been demonstrated using in vitro receptor phosphorylation assays,  confirming biological activity in human cells. Finally, SemBioSys has  demonstrated functional equivalence through conducting insulin tolerance  testing in mice, which monitors blood glucose levels as the assay variable, confirming that there is no statistically significant difference in the  pharmacodynamic response of safflower-produced insulin in comparison to Eli  Lilly's Humulin(R) and U.S.P. insulin treatments.

    "The equivalence results demonstrate that we have done what we said we  were going to do, when we said we would do it, which continues to build our  confidence in the insulin program. With the achievement of commercial  levels of insulin accumulation in safflower and confirmation of equivalence , our ability to execute continues to be critically important, however, the  overall insulin program risk has now been significantly reduced. Insulin is  a well-characterized compound for which a great deal of data already exists . With these high-risk scientific achievements behind us, we now transition  to the execution stage of our clinical development plan for insulin," said  Mr. Baum.

    The results from the equivalence testing are the most recent achievement in a series of four significant milestones events for the insulin program. In July 2006, SemBioSys exceeded its target level of insulin accumulation in safflower. In November, SemBioSys signed an agreement with Cangene Corporation to purify safflower-produced insulin  from SemBioSys' seed lines under cGMP for clinical trials. Finally, earlier  this month SemBioSys announced that after meeting with the U.S. Food and  Drug Administration (FDA) it would proceed with an abbreviated regulatory  path for safflower-produced insulin under a 505(b)(2) application. The  Company expects to be in a position to submit an IND to the FDA in the  second half of 2007 and to initiate a PK/PD bioequivalence study in late  2007 or early 2008 to be followed by a Phase III study in support of an NDA.

    Demand for insulin for the treatment of diabetes reached an estimated  5,000 to 6,000 kilograms in 2005 and is projected to increase to 16,000  kilograms by 2012. Demand for insulin is expected to grow due to a number  of issues including; earlier diagnosis of diabetes; increased diabetes  incidence in the developed world due to demographic trends, as well as  consumption and behavioural habits; increasing incidence in the developing  world due to increasing affluence and changing dietary habits; new  alternative delivery methods that require between five and ten times the  amount of insulin as injection methods; and the use of insulin as a  treatment for type 2 diabetes patients earlier in the treatment protocol as recommended by the consensus statement from the American Diabetes Association and the European Association for the Study of Diabetes.

    SemBioSys believes its safflower-produced insulin can reduce capital  costs compared to existing insulin manufacturing by up to 70% and product  costs by 40% or more. Insulin currently produced using fermentation is  estimated to require US$200 to US$250 million in capital investment for  1,000 kilograms of production capacity. In addition, because of the ease in  scaling-up crop acreage, plant-produced insulin offers significant  improvements in the flexibility and speed of scale-up. SemBioSys has five  years of experience growing transgenic safflower in Canada, the U.S.,  Mexico and Chile under permits issued by the pertinent regulatory authorities.
