USDA agrees to grant conditional license for
E. Coli cattle vaccine
Bioniche Life
Sciences Inc. (TSX: BNC), a research-based, technology-driven Canadian
biopharmaceutical company, received notice from the United States
Department of Agriculture (USDA) on Tuesday that the latest data for its
E. coli O157:H7 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 vaccine.
The Bioniche
vaccine is the world's first vaccine that may be used as an on-farm
intervention to reduce the amount of E. coli O157:H7 shed by cattle.
Bioniche and
its collaborators have been moving the vaccine towards commercial
availability for eight years and it has been extensively tested at the
University Nebraska-Lincoln, with efficacy results now being published
in peer-reviewed scientific journals, most recently, the Journal of Food
Protection, in November 2007.
The E. coli
O157:H7 cattle vaccine will be manufactured in the Bioniche production
facility in Belleville, Ontario, Canada where a two-year, $25 million
expansion is taking place. Vaccine supply will be limited during this
manufacturing expansion period.
"This is a
large step forward for the E. coli O157:H7 vaccine," said Graeme McRae,
President & CEO of Bioniche Life Sciences Inc. "The granting of a U.S.
conditional license will permit U.S. beef and dairy producers access to
a scientifically-validated means to reduce the risk of E. coli O157:H7
contamination."
Rick Culbert,
president of Bioniche food safety, added, "There are an estimated 97
million cattle in the United States, many of which carry and shed E.
coli O157:H7. We look forward to working with producers to implement
vaccination as the first licensed on-farm intervention for E. coli risk
reduction."
In order to
begin providing vaccine to U.S cattle producers, the company is required
to produce three validated production lots, which will be filled in the
United States, in accordance with the Virus-Serum-Toxin Act of 1913, as
amended 1985.
It has taken
some months for USDA reviewers to complete their assessment of vaccine
efficacy data against a pathogen with a complex life cycle in variable
real-world environments. Both the USDA and Bioniche have been diligently
working through these challenging issues with a view to benefiting
public health and the cattle industry.
"We are very
pleased that the USDA reviewers recognize the scientific merit and
importance to the market of this vaccine," added Mr. McRae. "The vaccine
is especially novel in that it reduces shedding of an organism that,
while potentially lethal to humans, causes no disease in cattle. As a
result, it was particularly challenging for regulators - understanding
the many implications of this vaccine as a tool in reducing the shedding
and colonization of E. coli O157:H7 in cattle."
Food recalls
due to E. coli O157:H7 contamination continue to be a concern in beef,
produce and prepared food. 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.
Approximately
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
hemolytic 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 |
