VGX Pharmaceuticals Announces DNA Vaccines License Agreement
with University of Pennsylvania
Blue Bell, PA – April 24, 2007 –

VGX Pharmaceuticals Inc. (VGX) announced today that it has signed a license agreement with the University of Pennsylvania covering novel DNA Vaccines and Therapeutics. Under the terms of the agreement VGX will have exclusive worldwide rights to develop a number of DNA plasmids and constructs with potential for the treatment and/or prevention of HIV, HCV, HPV and Influenza. This new agreement broadens the existing relationship between the two organizations. VGX was founded as a start-up in 2000 based on technology licensed from the University of Pennsylvania. VGX has previously licensed a number of product candidates and technology from the University of Pennsylvania and currently sponsors clinical research and basic research projects at the University.

The underlying technology was developed in the laboratory of Dr. David B. Weiner, Professor of Pathology and Laboratory Medicine at the University of Pennsylvania. Professor Weiner is a pioneer in the field of DNA vaccines and a VGX co-founder. Dr. Weiner’s laboratory has developed consensus sequences and antigens for key HIV, HCV, HPV, and Influenza proteins that offer coverage across different viral sub-types or taxonomic groups. Pre-clinical studies have shown that immunization of mice and non-human primates using the consensus DNA constructs for each virus elicits an immune response against multiple sub-types of the HIV, HCV, HPV, or Influenza viruses respectively.

“We are pleased to have access to this exciting technology as this significantly expands our development pipeline of a new generation of DNA-based therapies and vaccines for use in humans,” said Dr. J. Joseph Kim, President and CEO of VGX. “The new DNA vaccines, especially those targeting HIV and HCV, will strengthen and complement our infectious diseases programs, with PICTOVIR™ and VGX-410C programs currently in Phase II clinical trials in the US. Moreover, our recent acquisition of ADViSYS, Inc. provides VGX access to a proprietary DNA delivery technology and cGMP plasmid manufacturing capabilities. These new activities ensure that VGX will continue to be a global technology leader in this important field. We plan to move these exciting programs into clinical evaluation as soon as possible.”

DNA-based vaccines and therapeutics deliver the immunogen or the therapeutic protein in the form of plasmid DNA encoding the protein of interest. The body then produces the protein of interest and elicits an immune response. Vaccination with DNA has multiple potential advantages over the present technology used for vaccination against a variety of infectious diseases. DNA vaccines are easier to manufacture, can be stored at room temperature and have the potential to more easily combine multiple antigens in one injection that would provide protection against multiple diseases or multiple targets from the same organism.
