SUCCESSFUL INJECTIONLESS DELIVERY OF VACCINES
(Aurora, Ontario) - Dr. Marianna Foldvari, Director of Pharmaceutical Research for Helix BioPharma Corp., and Dr. Lorne Babiuk, Director of the University of Saskatchewan's Veterinary Infectious Disease Organization, reported today at Helix's Annual General Meeting in Toronto that vaccines have been successfully delivered transdermally in mice utilizing the BiphasixTM delivery system.
These vaccine results complement the Company's earlier announcement in November 1998 that the BiphasixTM delivery system had been successfully used to deliver a large therapeutic protein, interferon-", transdermally without the need for an injection.
Furthermore, vaccine research using proprietary lipid-based delivery systems clearly showed that a single intranasal immunization generated a significant immune response in mice. When these immunized mice were exposed to the disease, they were 15 times more likely to survive than the mice which were not immunized.
According to Dr. Foldvari, these results signify a major step forward in the development of the Company's delivery systems for human and veterinary vaccine applications.
The market for vaccines is currently in excess of US$ 4 billion worldwide and growing at more than 10% per year.
With most vaccines and macromolecular therapeutics being delivered by injection, and more than 500 such large molecules and vaccines in the regulatory process in the United States, the BiphasixTM delivery system has the potential to replace or complement injections by taking molecules of varying sizes into and through the skin.
