VGX Pharmaceuticals Receives $1.9 Million Contract from U.S. Government
to Develop Skin Micro-Electroporation for Improved Biodefense Vaccine Efficacy

Blue Bell, PA – September 10, 2007 –

VGX Pharmaceuticals announced today that it has been awarded a contract from the Defense Threat Reduction Agency (DTRA) to develop VGX’s constant current electroporation technology for intradermal (ID) delivery of DNA vaccines and therapeutics. The contract is for $1.9 Million over 12 months. Under the contract, VGX will demonstrate in vivo efficacy of novel vaccines derived from DNA plasmid-based pox virus antigens delivered using a skin micro-electroporation system.

The development of candidate countermeasures to chemical and biological warfare agents represents a major thrust of the US Government’s Chemical and Biological Defense Initiative. Smallpox is classified as a CDC category A pathogen. Although this highly contagious and often fatal virus was eradicated in 1979, it affected almost 1 billion people since the late 19th century and has a high biothreat potential today.

"This contract demonstrates the U.S. government’s support of in vivo electroporation for the delivery of DNA vaccines as a defense against bioterrorism, and further encourages the development of the skin micro-electroporation platform for our pipeline," stated Dr. J. Joseph Kim, President and CEO of VGX. “We are excited to be awarded this contract to further validate the skin-delivery system for immunogenicity and efficacy in a pathogen of particular interest to the DTRA and set the platform for delivery of other vaccines in the biodefense program.”

VGX is developing the CELLECTRA™ electroporation device to deliver a number of DNA vaccine and therapeutic candidates for both ID and intramuscular (IM) routes. The device is portable, water-proof, shock-proof, battery operated, and software driven, making it particularly suited for usage in the field. Delivery of vaccines via the CELLECTRA™ skin micro-electroporation system may have several potential advantages such as lower dosage and higher tolerability.

VGX has established a dynamic vertically-integrated product development platform encompassing novel DNA vaccine constructs, proprietary electroporation technology for DNA delivery, and an efficient process for the cGMP manufacturing of DNA plasmids. VGX is currently developing a portfolio of DNA based vaccines covering HIV, HPV and influenza as well as DNA therapies for cancer-related cachexia based on growth hormone releasing hormone (GHRH). These potential products are anticipated to be developed for human applications in combination with the CELLECTRA™ electroporation device. VGX has initiated the formal IND-enabling toxicology studies for its HPV, influenza, and GHRH product candidates in Q3 2007.
