Data from TNFerade(TM) Esophageal Cancer Study Presented at 2010 ASCO Gastrointestinal Cancer Symposium

GAITHERSBURG, Md. — GenVec, Inc. (Nasdaq: GNVC) announced today that data from the Company’s trial in esophageal cancer were presented at the American Society of Clinical Oncology’s 2010 Gastrointestinal Cancer Symposium in Orlando, Florida on January 22, 2010.

The poster, titled, “Long term survival analysis of multicenter clinical trial using endoscopy (END) and endoscopic ultrasound (EUS) guided fine needle injection (FNI) of antitumor agent (TNFerade Biologic (TNF)) in patients with locally advanced esophageal cancer,” reports on updated efficacy and survival data. In the 24 patients receiving TNFerade in combination with chemoradiation, the median survival was 47.7 months.  Median survival from other historical clinical trials in similar stage disease ranged from 9.7 to 34 months.

Research presented in the poster received a prestigious ASCO Foundation Merit Award. In addition, the poster received focused attention at the oral review session on esophageal cancer on January 22, 2010.

“This symposium brings together the greatest thought leaders in this area of oncology and we are pleased to be presenting this analysis at this event,” stated Mark Thornton, Ph.D., GenVec’s Senior Vice President of Product Development. “The encouraging increases in survival versus historical controls will warrant additional evaluation.”
