Research & Development

18.05.2007

Vienna (Austria), May 18, 2007 - Intercell AG (VSE, "ICLL") has been
informed by its strategic partner Merck & Co., Inc. on the results
of a Phase I study involving in total over 120 adult healthy
volunteers comparing safety and immunogenicity of different doses of
the Staphylococcus aureus vaccine.

The Staphylococcus aureus vaccine is based on a conserved protein
antigen discovered by Intercell´s Antigen Identification Program
(AIP®) and was licensed to Merck & Co., Inc. on an exclusive world
wide basis in 2003.

The data show that the vaccine is safe and generally well tolerated.
Immune responses were observed within several weeks following
vaccination and these immune responses persisted throughout the
course of the study.

"We are very pleased that the vaccine candidate, for which the
antigen was identified by our proprietary AIP® technology, delivered
promising clinical data, and look forward to its further clinical
development ", states Gerd Zettlmeissl, CEO of Intercell. "These data
underline the high potential of our AIP® technology for the
identification of other bacterial vaccine product candidates in-house
or in collaboration with leading vaccine companies".

About Staphylococcus aureus and nosocomial infections

Hospital-acquired infections are one of the major causes of death and
serious illness worldwide, resulting in an annual burden of more than
USD 20 billion in the developed world. In the United States alone,
about two million patients become infected annually while receiving
health care in hospitals. The incidence of nosocomial infections is
steadily increasing due to medical interventions and most notably due
to the emergence of antibiotic resistant bacteria circulating in
hospitals. Staphylococcus aureus is the most frequent cause of
hospital acquired infections. In addition to bloodstream infections
with a mortality rate of up to 35%, infections of bone, heart and
other inner organs are leading to serious health complications, death
and economic burden. Today, approximately 50% of Staphylococcus
aureus strains isolated in hospitals worldwide are resistant to
multiple antibiotics, rendering staphylococcal disease management
increasingly difficult and challenging.
