Generex Biotechnology Awarded New U.S. Patents for Its Core Vaccine Technologies

WORCESTER, MA--(Marketwire - June 14, 2007) - Generex Biotechnology Corporation (NASDAQ: GNBT) announced today that its wholly owned subsidiary, Antigen Express, Inc., has been awarded two new United States patents strengthening its core vaccine technology platform. The first patent, titled Ii-Key/Antigenic Epitope Hybrid Peptide Vaccine, and the second patent, titled Hybrid Peptides Modulate the Immune Response, both help secure the novel Antigen Express vaccine technology platform which is the foundation for a number of vaccine products presently in clinical development.

Proprietary immunotherapeutic cancer vaccines as well as prophylactic vaccines for infectious disease derive increased protection under these patents. The most advanced product is an immunotherapeutic vaccine that has entered Phase II clinical trials in breast cancer patients. The same compound is being tested in a Phase I clinical trial in prostate cancer patients. In addition, other hybrid peptide vaccines, based upon the same technology, are being tested in a Phase I clinical trial for their ability to generate an immune response against the potentially pandemic H5N1 avian influenza virus. To date, these types of epitope hybrid peptide vaccines have been tested in over 115 individuals and appear to be safe and well-tolerated.

The increased activity of peptide vaccines designed using this technology is the result of their ability to potently stimulate CD4+ T helper cells to recognize specific pathogenic agents. T helper cells play a critical role in enabling the immune system to recognize novel agents and establishing immunological 'memory.'
