Cardiology's 59th Annual Scientific Session

TSX symbol: SBS

CALGARY, March 12 /CNW/ - SemBioSys Genetics Inc. (TSX:SBS), specializing in the manufacture of high-value proteins and oils in plant seeds, today announced that its collaborators at the Cedars-Sinai Heart Institute, under the direction of Dr. Prediman K. Shah, will present the results of a preclinical study with its Apo AI(Milano) candidate at the American College of Cardiology's (ACC) 59th Scientific Sessions in Atlanta. The poster presentation entitled: "Safflower Seed-derived Des-1,2-apo AI(Milano) Reduces Atherosclerosis in Hypercholesterolemic Apolipoprotein E (-/-) Mice" by Dr. Kuang-Yuh Chyu and colleagues (number 1022-116) will take place at the Georgia World Congress Center, Hall B5 on Sunday, March 14th. The abstract for the presentation will be made available on the SemBioSys website at http://www.sembiosys.com/Products/Stroke.aspx.

The poster presentation details results from preclinical studies with SemBioSys' Apo AI(Milano) candidate, a leading edge biopharmaceutical that represents a new paradigm in the treatment of cardiovascular disease. The protein is manufactured using the Company's proprietary platform, which allows for highly scalable, low cost production of pharmaceutical proteins with a high level of purity. The studies successfully demonstrate that a phospholipid complex containing SemBioSys' Apo AI(Milano) positively impacted the three key components required to achieve a therapeutic effect. The data demonstrated an increase in cholesterol efflux capacity (the ability to remove cholesterol from the vessel wall), an increase in circulating levels of free cholesterol and a reduction in atherosclerosis.

Apo AI is the major apolipoprotein associated with HDL (high density lipoprotein), commonly referred to as "good cholesterol", which naturally removes plaque from arteries. Clinical studies by an external party have shown that Apo AI(Milano), which is a variant of Apo AI in a phospholipid formulation, could reduce plaque volume at a level and speed unattainable with any current drug therapy.
