SYNTHETIC BIOLOGICS AND FUJIFILM DIOSYNTH BIOTECHNOLOGIES UK ANNOUNCE SIGNIFICANT IMPROVEMENT IN API MANUFACTURING OF SYN-004 FOR THE PREVENTION OF C. DIFFICILE
Fujifilm’s pAVEway™ Platform Demonstrated >25-fold Improvement in SYN-004 Expression Titers
Rockville, MD, August 28, 2014 – Synthetic Biologics, Inc. (NYSE MKT: SYN), a developer of novel anti-infective biologic and drug candidates targeting specific pathogens that cause serious infections and diseases, and FUJIFILM Diosynth Biotechnologies UK Limited (Fujifilm), announced today confirmation of exceptional results from the initial phase of cGMP manufacturing of SYN-004, Synthetic Biologics’ proprietary oral beta-lactamase enzyme for the prevention of Clostridium difficile (C. difficile) infections.
The initial 750-liter cGMP production run on Fujifilm’s pAVEway™ platform yielded an unprecedented 5.5 kilograms of >95% pure SYN-004 active pharmaceutical ingredient (API) drug substance, which will be used to support Synthetic Biologics’ planned Phase I and II clinical trials, and continued research and development studies.
SYN-004 is believed to be the first and only therapy designed to neutralize intravenous (IV) antibiotics in the gut. It is intended to protect and maintain the balance of bacterial flora in the gastrointestinal (GI) tract, or gut microbiome, and to potentially prevent the devastating effects of C. difficile infection. Research continues to demonstrate that protection of the microbiome plays an increasingly important role in the prevention of a variety of GI, metabolic and CNS disorders. The U.S. Centers for Disease Control and Prevention (CDC) have classified C. diff as an “urgent public health threat”, surpassing Methicillin-resistant Staphylococcus aureus (MRSA) as the number one hospital-acquired infection in the United States. C. difficile is a multidrug-resistant bacterium that infects 1.1 million U.S. patients annually, and 30,000 patients die with a C. difficile infection annually.
“We are extremely impressed by the quality, quantity and efficiency of the initial SYN-004 API manufacturing work by Fujifilm,” stated Jeffrey Riley, Chief Executive Officer of Synthetic Biologics. “Fujifilm not only exceeded our yield expectations, but also provided exemplary customer service through its diligent approach and skillful execution in developing the cGMP process for SYN-004.”
Mr. Riley concluded, “Importantly, with a solid new GMP manufacturing process, Synthetic Biologics remains on schedule to file an Investigational New Drug (IND) application for SYN-004, and initiate Phase Ia and Ib clinical studies for the prevention of C. difficile infection in the second half of 2014. Preliminary Phase I topline data is expected by year-end 2014, and a Phase II efficacy study of SYN-004 is planned to begin in the first half of 2015.”
The GMP manufacturing process was initiated after a successful evaluation by Fujifilm that produced high yielding cell lines that exhibited consistent biological activity of SYN-004. Fujifilm successfully improved SYN-004 expression titers by greater than 25-fold (14 grams of SYN-004 per liter of culture broth), compared to the Bacillus platform previously employed for SYN-004’s first-generation predecessor. Fujifilm’s pAVEway™ platform (an E. coli system) utilizes proprietary expression vectors harboring palindromic DNA looping to provide tightly controlled gene expression, which can enable very high expression levels. The newly developed, single chromatography column purification process reproducibly yielded 40-50% SYN-004 drug substance recovery at purity levels great than 95%, another marked manufacturing improvement over the previous purification process.
Steve Bagshaw, Chief Executive Officer of FUJIFILM Diosynth Biotechnologies said, "We are pleased to demonstrate the remarkable versatility of our pAVEway™ expression system, and support Synthetic Biologics’ clinical development of its SYN-004 product. We look forward to a productive relationship with Synthetic Biologics as its API supplier."

In some cases forward-looking statements can be identified by terminology such as "may," "should," "potential," "continue," "expects," "anticipates," "intends," "plans," "believes," "estimates," and similar expressions. These statements are based upon current beliefs, expectations and assumptions and are subject to a number of risks and uncertainties, many of which are difficult to predict and include statements regarding the intended effects and potential impact of SYN-004, the timing of initiation of the Phase Ia and Ib clinical studies, the preliminary Phase I topline data and initiation of Phase II efficacy study and the expected size of the market for C. diff therapeutics. The forward-looking statements are subject to risks and uncertainties that could cause actual results to differ materially from those set forth or implied by any forward-looking statements. Important factors that could cause actual results to differ materially from those reflected in Synthetic Biologics’ forward-looking statements include, among others, our inability to timely commence or complete the clinical trials consistent with our current expectations and otherwise demonstrate the ability of SYN-004 to have a significant impact on mitigating the effects of C. difficile, our ability to successfully manufacture cGMP product, receive regulatory approvals for or to commercialize a new product candidate to prevent C. diff infection and other factors described in Synthetic Biologics’ report on Form 10-K for the year ended December 31, 2013 and any other filings with the SEC.
