Promising Data Presented on GenVec RSV Program

GAITHERSBURG, Md., Oct. 1, 2012 /PRNewswire/ -- GenVec, Inc. (Nasdaq: GNVC) announced today that data were presented on GenVec's respiratory syncytial virus (RSV) vaccine program at the "8th Annual International Respiratory Syncytial Virus Symposium," which took place in Santa Fe, New Mexico from September 27-30, 2012.

Data presented at the conference demonstrated GenVec's universal RSV vaccine candidate is highly immunogenic and produces durable and broad protection from a single intramuscular administration. Protection in cotton rat and mouse models was characterized by functional RSV neutralizing antibodies and no disease potentiation was observed. GenVec's RSV vaccine candidate utilizes a proprietary adenovirus that is capable of generating a broad immune response while avoiding the problems of vector specific immunity that has hampered other vectored vaccines.

"Preclinical studies in accepted animal models show that our vaccine candidate has the desired efficacy and safety attributes required for a successful RSV vaccine," stated Jason Gall, PhD, Senior Director of Research at GenVec and the company's lead RSV scientist. "GenVec has received valuable input from the FDA on the clinical plan for the vaccine and will continue to explore opportunities to move the program forward with a partner."

About Respiratory Syncytial Virus

RSV is the single most important viral cause of lower respiratory infections in infants and young children and there is no approved vaccine. According to the World Health Organization, nearly all U.S. children have been infected with RSV by two years of age. Although RSV infection usually produces cold-like symptoms, the infection can result in severe lower respiratory tract infection, which causes up to 130,000 pediatric hospitalizations per year in the U.S. RSV also causes repeated infections throughout life, placing the elderly and individuals with compromised cardiac, pulmonary, or immune systems at risk for severe disease. Among the institutionalized elderly, it is estimated there are about 15,000 deaths annually from RSV.
