Oragenics Advances Towards Identification of Lead Antibiotic Clinical Candidate

Lantibiotic Pipeline through Exclusive Channel Collaboration with Intrexon Generates Several New MU1140 Analogs with Activity Against Certain Drug-Resistant Bacteria

TAMPA, Fla.-- Oragenics, Inc. (NYSE MKT: OGEN) announced today that through its Exclusive Channel Collaboration (ECC) with Intrexon Corporation (NYSE: XON), a leader in synthetic biology, it has produced and analyzed a large number of new potential analogs generated from its Mutacin 1140 (MU1140) lantibiotic program platform, and advanced several promising compounds for further evaluation. These compounds will serve as the basis for selecting a lead drug candidate for clinical development later this year. The triaged analogs were selected from hundreds of variants generated using genetic engineering at Intrexon.

Dr. John N. Bonfiglio, Chief Executive Officer of Oragenics, remarked, "The compounds we have selected for final evaluation align with our goal of identifying the first lead compound this year. We plan on meeting with the FDA later this year to discuss the IND enabling activities necessary to submit an IND application by mid-2015. Intrexon’s synthetic biology expertise in collaboration with our scientists has enabled generation of a large library of new potential MU1140 analogs with chemical and biological properties that differentiate from native MU1140. We remain very optimistic that these new lantibiotics will become useful in the fight against certain drug-resistant bacteria.”
