About Inovio Pharmaceuticals, Inc.

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