BLUE BELL, Pa., June 30, 2011 /PRNewswire/ -- Inovio Pharmaceuticals, Inc. (NYSE Amex: INO), a leader in the development of therapeutic and preventive vaccines against cancers and infectious diseases, announced today that it has achieved compelling immune responses in a study of its multi-subtype DNA vaccine for foot-and-mouth (FMD) disease administered by Inovio's proprietary vaccine delivery technology in sheep, the second large animal in which this vaccine was evaluated. Strong protective neutralizing antibodies were also observed in pigs vaccinated with the same Inovio FMD vaccine. These results were presented by Dr. Niranjan Y. Sardesai, Inovio Sr. VP of Research and Development, at the Biochemical and Molecular Engineering XVII Conference in Seattle in a talk titled "Engineering Effective Consensus DNA Vaccines." Today's FMD vaccines based on killed/inactivated viruses can actually cause FMD infection, so are only used regionally after an outbreak rather than for broad preemptive vaccination. Inovio's synthetic DNA vaccine cannot cause the disease, providing a safe approach to potentially protect against FMD and reduce its serious impact on global food supply and commerce.
The FMD virus is one of the most infectious agents causing significant disease in farm animals including cattle, swine, sheep and goats. Once an area is exposed to FMD, livestock & dairy exports are ceased and herds are culled. For example, in a major FMD outbreak in the UK in 2001, more than 4 million animals were slaughtered, resulting in more than $10 billion (USD) in economic losses. In a current FMD epidemic in South Korea, more than 3.3 million animals, mostly swine, have been culled in an attempt to keep the disease from spreading.
Because FMD can spread rapidly and beyond regional boundaries there is a need to develop vaccines that can simultaneously target different regional seroty
