Oragenics Collaboration Demonstrates Initial Success in the Second Phase of Lantibiotics Project

TAMPA, Fla.-- Oragenics, Inc. (NYSE MKT: OGEN) announced today that through its Exclusive Channel Collaboration (ECC) with Intrexon Corporation (NYSE:XON), a synthetic biology company, preliminary experiments demonstrate that a genetically-modified (GM) host can be engineered to produce improved titers of OGEN’s lead compound MU1140, progressing towards the commercial production of lantibiotics, a novel-class of broad-spectrum antibiotics.

The collaboration has also uncovered two new methods of purifying its lead compound resulting in higher purity and yields of MU1140. The next step will be to use the GM host to produce analogs of MU1140 that are expected to demonstrate improved antimicrobial, chemical and pharmacological properties, with the objective of building a comprehensive antibiotic pipeline against various life-threatening indications.

"The ability to produce MU1140 by fermentation was originally thought not to be commercially feasible due to low titers and purification issues. The Oragenics-Intrexon ECC has shown that the application of specific expertise in key areas may enable a viable commercial strategy and ultimately bring these important drugs into human clinical studies," stated Dr. John N. Bonfiglio, Chief Executive Officer of Oragenics. “Preclinical development plans are currently being designed by our R&D team, which includes well-respected experts in the area of antibiotic commercialization,” Dr. Bonfiglio further stated.

In June 2012, Oragenics and Intrexon entered into an ECC to develop and commercialize lantibiotics for the treatment of infectious diseases. The companies are pursuing a pipeline of new lantibiotics that are particularly active against a variety of Gram positive bacteria that are resistant to drugs of last resort.
