"This financing will fully fund our planned Phase II clinical study for our DNA vaccine against cervical dysplasias and cancers, as well as other clinical studies that Inovio intends to directly fund and launch in 2011. The additional capital will also allow us to more rapidly advance other promising preclinical DNA vaccine programs toward the clinic, and we believe we now have sufficient cash to cover our operations into 2014," noted Dr. J. Joseph Kim, President and CEO.

About Inovio Pharmaceuticals, Inc.

Inovio is developing a new generation of vaccines, called DNA vaccines, to treat and prevent cancers and infectious diseases. These SynCon(TM) vaccines are designed to provide broad cross-strain protection against known as well as newly emergent strains of pathogens such as influenza. These vaccines, in combination with Inovio's proprietary electroporation delivery devices, have been shown to be safe and generate significant immune responses. Inovio's clinical programs include HPV/cervical dysplasia and cancer (therapeutic), avian flu (preventive), and HIV vaccines (both preventive and therapeutic). Inovio is developing universal influenza and other vaccines in collaboration with scientists from the University of Pennsylvania. Other partners and collaborators include Merck, National Cancer Institute, U.S. Military HIV Research Program, NIH, HIV Vaccines Trial Network, National Microbiology Laboratory of the Public Health Agency of Canada, and PATH Malaria Vaccine Initiative.
