ROCKVILLE, MD, USA I September 7, 2014 I Synthetic Biologics, Inc. (NYSE MKT: SYN), a biotechnology company developing novel anti-infective biologic and drug programs targeting specific pathogens that cause serious infections and diseases, announced today preclinical data that further validate the Company’s novel approach to preventing Clostridium difficile (C. difficile). The U.S. Centers for Disease Control has identified C. difficile as an “urgent public health threat,” and it has surpassed MRSA as the number one hospital-acquired infection in the United States. The data were highlighted on September 6th at the 54th Interscience Conference on Antimicrobial Agents and Chemotherapy (ICAAC), in Washington, D.C.

Synthetic Biologics’ Senior Vice President, Research & Development, Mike Kaleko, M.D., Ph.D., presented a late-breaking poster demonstrating the broad activity of its lead anti-infective candidate SYN-004 (P3A), as well as a potential pipeline candidate, P4A, for C. difficile prophylaxis. Both SYN-004 and P4A effectively degraded a broad spectrum of commonly used intravenous (IV) antibiotics that can lead to C. difficile infections, including cephalosporins.

“We were honored to have the opportunity to present our novel program for the prevention of C. difficile infection, including both SYN-004 and P4A. SYN-004 is designed to protect the gastrointestinal (GI) microflora – or gut microbiome – from the effects of certain commonly used IV antibiotics, thereby preventing C. difficile infection,” said Jeffrey Riley, Chief Executive Officer of Synthetic Biologics. “We are in the final stages of preparing the Investigational New Drug (IND) application for SYN-004, with the expectation of initiating Phase Ia and Ib clinical trials in the fourth quarter of 2014, and a Phase II efficacy study in the first half of 2015.”

About C. difficile Infections

C. difficile is classified by the CDC as an “urgent public health threat,” given its high prevalence and resistance to many drugs used to treat other infections. It affects 1.1 million Americans and causes 30,000 deaths each year,[i],[ii] adding an estimated four to seven hospitalization days per patient[iii] and $8.2 billion in overall annual hospital costs.[iv] C. difficile infections are strongly associated with the use of IV antibiotics, which are administered to more than 24 million Americans annually to prevent or treat infections.[v] These powerful antibiotics can create a harmful imbalance in the gastrointestinal tract by wiping out helpful, “good” bacteria, and allowing C. difficile to grow out-of-control, leading to severe diarrhea, damaging the colon, and in some cases, death.[vi]
