Hepatitis C Therapeutic DNA Vaccine Delivered by Inovio Biomedical's Electroporation Technology Reduces Viral Load by Up to 99.7% : Clinical Data Presented at Annual Scientific Meeting of the American Association for the Study of Liver...( Inovio Biome...),Health

Inovio Biomedical Corporation (AMEX:INO), a leader in enabling the development of DNA vaccines using electroporation-based DNA delivery, announced today that its partner, Tripep AB, reported positive additional interim results from its ongoing phase I/II clinical study of its therapeutic DNA vaccine against hepatitis C virus (HCV). This vaccine is being delivered using Inovio’s electroporation-based DNA delivery system. In the third and highest dose cohort of the study, two of three subjects demonstrated reductions in viral load of 93% and 99.7%. Previously reported middle dose cohort results demonstrated an 87% and 98% reduction in HCV in two of three subjects, while no anti-viral effect was observed in the low dose cohort. No safety issues have been noted to date in the trial. These data suggest a potential dose response of the vaccine and support the inclusion of three additional subjects in the high dose cohort.

SAN DIEGO (Business Wire EON) November 17, 2008 -- These data where presented by Dr. Matti Sllberg of Tripep at the recent American Association for the Study of Liver Diseases meeting held in San Francisco.

Avtar Dhillon, MD, Inovio's president and CEO, stated: "We continue to be encouraged by the data flowing out of the ChronVac-C study. This promising DNA vaccine candidate, in which Inovio has an ownership position, is one of the more advanced clinical vaccine candidates in the HCV field. ChronVac-C was designed to play a role as a first-line therapy or as an adjunct to existing therapies."

About ChronVac-C

ChronVac-C is a therapeutic DNA-based vaccine given to individuals already infected with the hepatitis C virus with the aim of clearing the infection from the liver by boosting the body's immune response against the virus. Inovio's electroporation technology is being used to deliver the vaccine and is intended to enhance the
