Inovio Announces H7N9 DNA Vaccine Protects 100% of Vaccinated Animals


Inovio Pharmaceuticals, Inc. (NYSE: INO) announced today that in a preclinical study of its influenza DNA vaccine against the virulent, newly emergent H7N9 flu virus, 100% of the vaccinated animals were protected against sickness and death when they were challenged with a lethal dose of H7N9 virus. The results from a study in mice demonstrated that Inovio's vaccine generated not only hemagglutination inhibition (HAI)-based protection against the H7N9 virus but also strong T-cell responses. Inovio's DNA vaccine created cellular immune responses that could reduce the severity of the infection in a person that acquires the virus and limit the spread of the virus in a pandemic setting. Detailed study results will be presented at an invited plenary session at the TEPIK/APACI International Influenza Symposium being held in Seoul, South Korea, on July 12, 2013.

Inovio researchers constructed a consensus DNA vaccine targeting the HA influenza antigen based on sequences collected from several infected H7N9 patients to create a vaccine that is broadly protective against all
