VGX Pharmaceuticals Announces an R&D and License Agreement with
VGX International to Develop Gastric Cancer Therapeutics

Blue Bell, PA – June 20, 2007 –

VGX Pharmaceuticals announced today that the Company has granted VGX International, its Affiliate based in Seoul, Korea, a worldwide exclusive license to conduct research, development and marketing of VGX-100 for gastric cancer. Under the terms of this agreement, VGX Pharmaceuticals and VGX International will collaborate on pre-clinical as well as other phases of clinical trials for the development of VGX-100 for the gastric cancer indication. VGX Pharmaceuticals will receive milestone payments and royalties on the future sale of this product worldwide and has retained an option to develop VGX-100 in the US and Europe.

VGX Pharmaceuticals has developed technology using specific viral proteins that can induce selective apoptosis (programmed cell death) in rapidly dividing cancer cells, leaving normal cells unharmed. VGX-100, a recombinant viral protein r (Vpr), induces tumor cell death through apoptosis in number of human-derived tumor tissues including stomach, breast, prostate and brain.

Earlier this year, VGX has announced that VGX-100 will be manufactured using the Dowpharma’s Pf_nex Expression Technology™, a Pseudomonas-based technology. In addition, the scale-up development and clinical trial material manufacturing will be conducted by Diosynth Biotechnology, an Akzo Nobel Company.

“VGX-100 has been one of the most exciting product candidates in our preclinical development portfolio. Patients who are afflicted with gastric or stomach cancer currently have very little available treatment options,” says J. Joseph Kim, Ph.D., President and CEO of VGX Pharmaceuticals. “It is our goal to accelerate the development of VGX-100 by a close collaboration with VGX International.”
