Synthetic Biologics Announces Positive Topline Results from Phase 1a Trial of SYN-004 for the Prevention of C. difficile Infection
-- First-in-Class Drug Candidate to Prevent C. difficile Ahead of Schedule for Phase 2 Testing to Begin in 1st Quarter 2015 --
ROCKVILLE, Md., Dec. 22, 2014 /PRNewswire/ -- Synthetic Biologics, Inc. (NYSE MKT: SYN), a developer of pathogen-specific therapies for serious infections and diseases, with a focus on protecting the microbiome, today announced positive topline safety and tolerability results from a Phase 1a clinical trial of SYN-004, the Company's investigational oral beta-lactamase enzyme for the prevention of Clostridium difficile (C. difficile) infection, antibiotic-associated diarrhea and secondary antibiotic-resistant infections in patients receiving intravenous (IV) beta-lactam antibiotic therapy.
Since December 2nd, the randomized double-blind, placebo-controlled Phase 1a clinical trial conducted at Clinical Pharmacology of Miami, has enrolled 24 healthy volunteers in three cohorts of eight patients each. A total of 18 volunteers have been administered one dose of SYN-004 at increasing dose levels by cohort, and six volunteers received placebo. No clinically significant or relevant adverse events have been reported to date.
"Completing the first safety review and reporting positive topline results in the Phase 1a clinical trial of SYN-004 is an important event for Synthetic Biologics, bringing us closer to the first potential point-of-care preventative therapy for C. difficile, the CDC's top-ranking public health threat. Achieving this milestone moves us closer to validating our ground-breaking approach to preventing C. difficile infection in a way that protects the gut microbiome, which also holds the hope of treating a variety of GI, metabolic and CNS disorders," said Jeffrey Riley, Chief Executive Officer of Synthetic Biologics.
Mr. Riley added, "Based on the results observed in the first three cohorts, and per our clinical plan, we intend to proceed with our planned multiple-ascending dose placebo-controlled Phase 1b study of SYN-004, in which healthy volunteers will receive increasing doses of SYN-004 over several days. We expect enrollment into our Phase 1b SYN-004 clinical trial to begin before year-end, with topline data available during the first quarter of 2015. We also expect to initiate enrollment in a Phase 2 SYN-004 clinical trial ahead of schedule during the first quarter of 2015."
SYN-004 is Synthetic Biologics' oral drug candidate designed to be the first and only treatment intended to prevent C. difficile infection. Its mechanism of action is to bind with and neutralize certain common IV beta-lactam antibiotics in the gut. During 2012, 14.4 million U.S. patients received approximately 117.6 million doses of IV antibiotics[i] that could be inactivated in the gastrointestinal (GI) tract by SYN-004. SYN-004 is intended to block the unintended harmful effects of antibiotics within the GI tract, maintaining the natural balance of the bacterial flora (gut microbiome), potentially preventing the 1.1 million C. difficile infections[ii] and 30,000 C. difficile-related deaths[iii] in the United States each year.
The U.S. Centers for Disease Control (CDC) has identified C. difficile as an "urgent public health threat" and occurs mostly in people who have had recent medical care with IV antibiotics. These antibiotics can create a harmful imbalance in the gut microbiome by killing "good" bacteria, giving C. difficile a chance to multiply and cause diarrhea, which can lead to dehydration, fever, abdominal pain, cramping, nausea, colitis, and even death. In all, 24 million Americans receive IV antibiotics annually[iv].
