VGX Pharmaceuticals to present at the Second International Conference
on Cancer Vaccines/Adjuvants/Delivery

Blue Bell, PA – October 8, 2007 –

VGX Pharmaceuticals Inc. (VGX) announced today that Professor David B. Weiner of the University of Pennsylvania and Niranjan Y. Sardesai, VGX’s Vice President of Product Development, are scheduled to present at the Second International Conference on Cancer Vaccines/Adjuvants/Delivery for the Next Decade (CCADD) at The German Cancer Research Center in Heidelberg, Germany on October 10-12. Dr. Weiner, a VGX co-founder, is a pioneer in the field of DNA vaccines and is scheduled to present “DNA Vaccination in the Immunotherapy of Cancer” as part of the Conference’s Plenary Session. Dr. Sardesai will present “Enhanced Immune Responses to DNA Vaccines via Adaptive Electroporation” as part of the session on DNA Vaccines and Electroporation.

The three-day conference will focus on a variety of different approaches to cancer vaccines, including DNA based vaccination and immunotherapy, and will include international delegates from biotechnology companies, major pharmaceutical companies, academic institutions, and government labs. Over the last two decades, DNA vaccines have become a potent means of providing immune responses or protective immunity against viruses, bacteria and parasites in many species from fish to primates, including humans. Significantly, the first DNA based products in fish and dogs are on the market. A number of DNA vaccines, comprising plasmid DNA encoding proteins from pathogens, allergens, and tumors, are being evaluated as prophylactic vaccines and therapeutic treatments for infectious diseases, allergies and cancer. The use of DNA as a means of vaccination offers potential benefits in protective efficacy, cross-strain applicability, development speed and manufacturing cost compared with conventional vaccines.

Commenting on the conference proceedings, Dr. J. Joseph Kim, CEO and President of VGX said, “VGX is excited to be presenting at this conference showcasing the latest advances in cancer vaccines and immunotherapy. Our pre-clinical research studies demonstrate the broad applicability of our proprietary electroporation based CELLECTRA™ delivery platform beyond infectious diseases and into cancer.”

VGX has patented and developed the CELLECTRA™ electroporation device for the delivery of DNA vaccines and therapeutics. The company’s DNA-based oncology program includes: VGX-150, a DNA therapeutic, to control the growth of melanoma and other cancers; VGX-3100, a DNA vaccine targeting human papilloma virus (HPV) as a therapeutic for cervical cancer; and VGX-3200, a DNA-based therapeutic for the treatment of cancer related cachexia and anemia. Pre-clinical data from a mouse model show significant regression of established melanoma tumors after the introduction of VGX-150, using electroporation technology. Similarly, VGX has demonstrated regression of cervical cancer lesions and significant survival in an aggressive mouse model of cervical cancer when treated with the HPV vaccine compared to untreated controls. VGX-3100 and VGX-3200 are presently undergoing IND enabling pre-clinical GLP toxicology studies in combination with the CELLECTRA™ device. The company expects to file an IND for both of these products in the first quarter of 2008.
