Sanofi Pasteur and Statens Serum Institut Team Up Against Tuberculosis

    Scientific Advances in Vaccine Research may Lead to Improved Vaccine
    Against Leading Cause of Death in Developing Countries

    LYON, France, Feb. 14 /CNW/ - Sanofi pasteur, the vaccines division of
the sanofi-aventis Group, announced today that it has signed a collaborative
research and license agreement with the Statens Serum Institut of Denmark
(SSI) for the development and marketing of a new vaccine against tuberculosis
(TB), a disease that causes the death of two million people, worldwide, each
    Under the terms of the agreement, SSI has granted sanofi pasteur a
license to its technology with regard to the use of certain fusion proteins in
the development of a tuberculosis vaccine. The license from SSI includes
access to the Intercell IC31(R) adjuvant. If the development is successful,
sanofi pasteur would manufacture the vaccine commercially.
    SSI TB vaccine candidates are recombinant protein sub-units, including
one currently in a Phase I clinical trial. Results from a previous study
showed the SSI TB vaccine technology to provide a positive immune response.
Sanofi pasteur intends to build on the successes of the SSI vaccine program.
    "This agreement is a milestone for sanofi pasteur," said Wayne Pisano,
President and Chief Executive Officer of sanofi pasteur, which is also working
to develop a vaccine against another one of the biggest global infectious
disease killers--malaria.
    "The current medical arsenal is inadequate for fighting tuberculosis,"
Pisano continued. "Improved vaccines are desperately needed if we are to
succeed in controlling this disease. Sanofi pasteur and SSI are joining forces
to develop a vaccine that may have a major impact on global health by
preventing a disease that currently infects one person in the world every
    According to SSI's CEO, Nils Strandberg Pedersen, M.D., this agreement is
a very important step in the fight against tuberculosis and for SSI. "SSI is
one of the world's leading producers of BCG and has for more than a century
worked within the field of prevention and control of TB. We are excited to
team up our research with one of the world's largest vaccine manufacturers.
The combination of both parties' leading vaccine expertise will really be able
to make a difference in the development of a novel TB vaccine for the benefit
of the world's poorest people."
    The only TB vaccine (BCG--attenuated Bacille Calmette Guerin) used in the
world today was developed over 80 years ago. A TB vaccine is especially
important in areas of the world where TB is highly prevalent and the chances
of an infant or young child becoming exposed to an infectious case are high.
Although BCG is effective in protecting infants against childhood forms of the
disease, a more effective vaccine is needed for protection of adolescents and
adults against pulmonary tuberculosis.
    Professor Paul-Henri Lambert of the Centre of Vaccinology, University of
Geneva, and Chairman of the TBVAC consortium steering committee, agrees that
to effectively control TB, a new or improved vaccine must be developed as an
alternative to or a complement of BCG. "The development of an improved TB
vaccine has been a challenging goal for decades, but significant scientific
advances have been made over the past 15 years that bring us closer than ever
before to achieving this goal," explains Dr. Lambert. "Results obtained with
recombinant protein TB vaccine candidates in pre-clinical studies are
promising, and I am very optimistic about this approach leading to a new TB

    About Tuberculosis(2)

    More than eight million people develop active TB annually, and
approximately two million die from the disease each year. The World Health
Organization estimates that there are more than 14 million people living with
TB. Those with active TB who receive no treatment can infect an average of 10
to 15 people annually.
    Most TB cases occur in Southeast Asia and Africa. One-third of the number
of new TB cases occurs in Southeast Asia, but the estimated incidence per
capita is highest in sub-Saharan Africa. Both the highest number of estimated
deaths due to TB and the highest mortality per capita are in Africa, where HIV
has led to rapid increases in TB incidence. TB and HIV/AIDS form a lethal
combination, each speeding the other's progress.
