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.
