Staphylococcus aureus vaccine development on track safe and immunogenic in Phase I clinical trials

22-May-2007

Intercell AG 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 inhouse or in collaboration with leading vaccine companies".
