Oragenics Announces Breakthrough Antibiotic Analog Generation in Intrexon Collaboration

Marks Significant Step Towards Production of Lantibiotics and Pipeline Expansion

Engineers Genetically-Modified Host to generate Mutacin 1140 Analog(s)

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 successfully engineered a genetically-modified (GM) host to generate analogs of Oragenics’ lead lantibiotic compound Mutacin 1140 (MU1140). The successful production of the first generation analogs using the GM host demonstrates significant progress and proof-of-concept toward the eventual production of a pipeline of novel antibiotics. The MU1140 analogs may offer superior antibacterial activity and pharmacologic properties as compared to the native molecule.

In June 2012, Oragenics and Intrexon entered into an ECC to develop and commercialize lantibiotics, a novel class of broad-spectrum antibiotics, for the treatment of infectious diseases. The collaboration recently demonstrated initial success in producing improved titers of Oragenics’ lead compound MU1140 through a genetically engineered host, progressing toward the goal of commercial lantibiotic production. Lantibiotics are a class of antibiotics with a novel mechanism of action that are active against several multi-drug resistant infectious agents. The intractability of lantibiotic-sensitive organisms to acquire or develop resistance to lantibiotics has aroused significant interest in these molecules as novel therapeutic agents.

Dr. John N. Bonfiglio, Chief Executive Officer of Oragenics, remarked, "We anticipate that this proof-of-concept will enable eventual production of a pipeline of new MU1140 analogs and other lantibiotics, and marks an important milestone towards the goal of generating critically needed novel antimicrobicidal therapeutics."
