About Inovio's Immunotherapy Products

DNA-based immunotherapy products have the potential to by-pass inherent scientific obstacles of conventional vaccines that prevent their development for cancer and chronic infectious diseases such as HIV and hepatitis C. Pre-clinical data has indicated the potential ability of Inovio's technologies to safely and effectively deliver and significantly enhance the potency of such immunotherapies.

Inovio's DNA-based immunotherapy products consist of DNA plasmids and the Elgen and MedPulser DNA delivery systems. DNA plasmids are designed to express antigens that can induce an immune response specific to a cancer or infectious disease-causing organism. These plasmids are created synthetically and readily manufactured using well-established bacterial fermentation and purification technology. After a plasmid is delivered into muscle or tumor cells, production of the desired antigens may then induce a preventive or therapeutic immune response against the targeted disease. Inovio's advanced electroporation devices facilitate delivery and expression of such immunotherapies and have been shown in primate studies to boost antibody and T-cell immune response by orders of magnitude over DNA plasmid alone, suggesting the potential to provide better protection from complex infectious diseases such as HIV and hepatitis C as well as cancers such as prostate and breast cancers.

Inovio is poised to deliver advanced DNA-based immunotherapies, devices and know-how in this rapidly advancing field. The company is actively licensing its technology to pharmaceutical and biotechnology companies and supporting early stage clinical studies arising from
