EnWave Corporation Announces Positive Animal Vaccine Dehydration Results and New Testing Agreement with Saskatchewan Research Council
Published: Dec 16, 2010
VANCOUVER, BRITISH COLUMBIA--(Marketwire - December 16, 2010) - EnWave Corporation (TSX VENTURE: ENW)(FRANKFURT: E4U) ("EnWave" or "the Company") today announced that the Saskatchewan Research Council ("SRC") has demonstrated positive results in a set of viability and shelf-life tests designed to measure the potential benefits of EnWave's freezeREV™ Radiant Energy Vacuum ("REV") dehydration technology over the standard industry method for preserving pharmaceuticals in-vial, freeze drying. Conducted at the SRC Fermentation Pilot Plant in Saskatoon, Saskatchewan, on a live Escherichia coli ("E.coli") animal vaccine, the tests showed that the freezeREV™ single-vial prototype is capable of drying this vaccine in 50 minutes compared to 40 hours of freeze drying, with the same bacterial survival rates.
Following the successful dehydration test, samples were then placed into a six month shelf-life study at three different temperatures 4 degrees C, 22 degrees C and 37 degrees C (39.2 degrees F, 71.6 degrees F and 98.6 degrees F) to measure organism survival over time. Results from the study have shown that the freezeREV™ process is comparable to freeze drying, although survival rates were lower with the freezeREV™ samples stored at the highest temperature. Scientists from both SRC and EnWave believe that this result can be improved by making adjustments to the design of the technology, and the two companies have now signed a Testing Agreement ("the Agreement") to collaborate on the further development and testing of EnWave's recently announced multi-vial freezeREV™ prototype.
"SRC is very pleased with these results as they show promise for the pharmaceutical industry that so clearly needs to improve the speed and effectiveness of its current method of preserving vaccines for shipment and storage," said Dale Kelly, Vice-President of SRC's Agriculture, Biotechnology and Food Division. "EnWave's freezeREV™ is an excellent example of Canadian ingenuity and innovation at work, and our organization is keen to move to the next step with EnWave in developing this exciting technology."
"Over the past three years, freezeREV™ has shown a great deal of promise as a high-speed dehydration method for a wide variety of biomaterials in vials including bacteria, enzymes, antibodies and viruses," said Dr. Tim Durance, EnWave's Chairman and Co-CEO. "I am very much looking forward to the next stage of development for this technology, and to continuing our productive and cost-effective relationship with SRC."
EnWave's proprietary Radiant Energy Vacuum ("REV") technology combines microwave energy with vacuum pressure to produce high-speed dehydration of live or active pharmaceuticals and other biomaterials stored in vials. The Company has developed two versions of REV for this sector: bioREV™, a dehydration method for materials which require a gentler drying process without extreme temperature changes or freezing, and freezeREV™, an accelerated freeze drying method for material where low moisture levels in the final product are imperative for long product shelf-life.
SRC is Saskatchewan's leading provider of applied R&D and technology commercialization. It takes the leading-edge knowledge developed in Saskatchewan and sells it to the world and, at the same time, brings the best knowledge the world has to offer and applies it to unique Saskatchewan situations. SRC, a Treasury Board Crown Corporation, was established in 1947 to advance the development of the province in the physical sciences. Today, SRC has evolved to become a market-driven corporation, selling sevices and products to companies in Saskatchewan and around the world. The company currently has more than 400 employees. Annual revenues are over $42.6 million and growing. More information is available about SRC at www.src.sk.ca.
Using proprietary technologies developed in conjunction with the University of British Columbia, EnWave is commercializing a new method for dehydrating food and biological materials using Radiant Energy Vacuum ("REV") technology under its nutraREV™, powderREV™, bioREV™ and freezeREV™ brands. REV technology combines microwave energy transfer under vacuum to dehydrate and alter structures and drive chemical reactions, thereby creating unique product characteristics for both food products and medical applications that include fruit, vegetables, probiotics, enzymes, proteins, food cultures, vaccines and antibodies.
