Canadian Regulator Recognizes Efficacy and Safety of Bioniche E. coli O157 Cattle Vaccine

    - clears path for full license -

    BELLEVILLE, ON, Sept. 24 /CNW/ - Bioniche Life Sciences Inc. (TSX: BNC),
a research-based, technology-driven Canadian biopharmaceutical company, has
received notice from the Canadian Food Inspection Agency (CFIA) that the data
package for its E. coli O157 cattle vaccine provides definitive evidence that
the vaccine meets the efficacy and safety requirements for full licensing of
the vaccine.
    Additional data confirming reduction in E. coli O157 shedding by
vaccinated animals was provided by the Company, which led to this recognition
from the CFIA. The most recent submission to the regulator involved data from
a controlled challenge study conducted at the Vaccine and Infectious Disease
Organization (VIDO) at the University of Saskatchewan. This study demonstrated
a significant reduction in the number of bacteria shed by vaccinated animals
and the number of animals shedding.
    The National Manager of the Veterinary Biologics Section, Animal Health
and Production Division of CFIA, Dr. Glen Gifford, stated, "Based on the
satisfactory results of the Bioniche-VIDO study, and supplemental information
from Bioniche's other studies, we have concluded that Bioniche has met the
efficacy and safety requirements for licensing of this product."
    As part of standard licensing requirements, the Company is required to
complete quality control tests on three pre-commercial batches to verify
consistency of manufacturing processes. The Company expects to meet these
requirements within the next few months.
    The Company was issued notification that it was allowed to distribute the
vaccine under the Permit to Release Veterinary Biologics Regulations by the
CFIA in December, 2006.
    "This news from CFIA is extremely encouraging," said Graeme McRae,
Chairman, President & CEO of Bioniche Life Sciences Inc. "We have demonstrated
definitive efficacy of the vaccine and, on completing one last task, we'll
have a full license in hand."
    The Company is concurrently working to meet the requirements for a U.S.
conditional license for the E. coli O157 vaccine. The United States Department
of Agriculture (USDA) informed the Company in February of this year that the
latest data for its E. coli O157 cattle vaccine "meets the 'expectation of
efficacy' standard" and is eligible for a conditional license, providing that
the Company develops a plan "that would collect sufficient data to move the
product to full licensure". The conditional license, when granted, will
provide the Company full access to the U.S. market with two restrictions: At
least one step in the manufacturing process must be performed in the United
States and Bioniche will not be permitted to use a trademark name for the
    Food recalls due to E. coli O157:H7 contamination continue to be a
concern in beef, produce and prepared food. This summer, a single U.S.
outbreak involved seven states and resulted in at least 60 serious human
infections following consumption of E. coli O157:H7-contaminated beef. On-farm
interventions to reduce the shedding of E. coli O157:H7 by cattle, such as
vaccination, may assist in reducing the potential for food and water
contamination and the resulting human illnesses and deaths.
    An estimated 100,000 cases of human infection with the E. coli O157:H7
organism are reported each year in North America. 2% to 7% of those people
develop haemolytic uremic syndrome (HUS), a disease characterized by kidney
failure (in recent outbreaks, this percentage has risen to as high as 16%).
Five percent of HUS patients die, many of them children and senior citizens,
whose kidneys are more sensitive to damage.
    In addition to being infected by contaminated food or water, individuals
can become infected from E. coli O157:H7 by visiting animal exhibits. Petting
zoos, fairs, and agricultural exhibits provide many possible routes of
transmission for E. coli. Direct animal contact is the obvious route, but
contact with contaminated products (e.g., sawdust, shavings, soiled clothing
or shoes) can also lead to human infection.
    The E. coli O157 cattle vaccine will be manufactured in the Bioniche
production facility in Belleville, Ontario, Canada where a two-year, $25
million expansion is taking place, supported by the Ontario and Canadian
governments. Vaccine supply will be limited during this manufacturing
expansion period.

    About the E. coli O157 Cattle Vaccine

    The Bioniche E. coli O157 cattle vaccine received international
recognition in September, 2007 at the Animal Pharm Industry Excellence Awards
as the best new veterinary product for livestock globally. The vaccine has
been developed by a strategic alliance formed in 2000 between the University
of British Columbia (UBC), the Alberta Research Council (ARC), the University
of Saskatchewan's Vaccine & Infectious Disease Organization (VIDO), and
Bioniche, which holds the rights for worldwide commercialization of the
vaccine. The vaccine prevents the E. coli O157 bacteria from attaching to the
intestines of vaccinated cattle, thereby reducing their reproduction within
the animal, and reducing the amount of bacteria that can be released through
cattle manure in the environment. More than 30,000 cattle have been involved
in clinical testing of the vaccine over the past five years. Two articles have
been published in a peer-reviewed journal, the Journal of Food Protection, in
regards to the efficacy of the Bioniche vaccine. These articles related to
field challenge studies conducted at the University of Nebraska-Lincoln
involving close to 900 animals in 2002 and 2003. Among the findings by
researchers Dr. David Smith and Dr. Rod Moxley et al: Vaccinating a majority
of cattle within a pen resulted in a significant protective effect to
unvaccinated cattle in the same pen. This effect is called "herd immunity".
Additional publications are pending.
