C. difficile Clinical Trial News; Synthetic Biologics Initiates SYN-004 Phase 2b Proof-of-Concept Clinical Trial

In The News……

Study to Evaluate SYN-004’s Ability to Prevent C. difficile Infection and Antibiotic-Associated Diarrhea
Phase 2b Trial Expected to Enroll Approximately 370 Patients at up to 75 Global Clinical Sites

Synthetic Biologics, a clinical-stage company focused on developing therapeutics to protect the microbiome while targeting pathogen-specific diseases, reported the initiation of its SYN-004 Phase 2b proof-of-concept clinical trial. The clinical trial is intended to evaluate the effectiveness of SYN-004 to prevent C. difficile infection (CDI), C. difficile associated diarrhea (CDAD) and antibiotic-associated diarrhea (AAD) in patients hospitalized for a lower respiratory tract infection and receiving intravenous (IV) ceftriaxone.

C. difficile is the leading type of hospital acquired infection and is frequently associated with IV antibiotic treatment. Beta-lactam antibiotics are a mainstay in hospital infection management, and include commonly used penicillin and cephalosporin antibiotics, such as ceftriaxone. However, antibiotics have the potential to cause harmful effects within the gastrointestinal (GI) tract including disruption of the natural balance of the gut microbiome, leading to 1.1 million CDIsi and 30,000 C. difficile-related deathsii in the United States each year.

SYN-004 is Synthetic Biologics’ oral prophylactic therapy designed to degrade certain IV beta-lactam antibiotics within the GI tract and maintain the natural balance of the gut microbiome for the prevention of CDI, AAD and emergence of antibiotic-resistant organisms.

“Initiating the SYN-004 Phase 2b clinical trial is an important milestone for Synthetic Biologics as it is intended to assess the proof-of-concept of SYN-004, which is designed to protect the microbiome and prevent CDIs and AAD,” stated Jeffrey Riley, Chief Executive Officer of Synthetic Biologics. “Several Phase 2b clinical sites are open for enrollment and actively screening for patients with additional sites expected to open as we approach the cold and flu season.”

Mr. Riley added, “Before initiating the SYN-004 Phase 2b clinical trial, safety and tolerability was demonstrated in two Phase 1 studies: a single-ascending dose study and a multiple-ascending dose study. Full analysis was completed and study reports were submitted to the FDA.

“In addition, our novel Phase 2a clinical trials are evaluating the GI antibiotic-degrading effects and the safety of SYN-004, both alone and in the presence of the proton pump inhibitor (PPI), esomeprazole, in participants with ileostomies (colon and rectum removed, or just part of small intestine removed). They are intended to generate additional pharmacokinetics (PK) and pharmacodynamics (PD) data to support SYN-004, and in the case of the PPI study, to analyze any potential drug-drug interactions.

“We have now enrolled enough participants to complete the first Phase 2a trial analysis, even though the recruitment of qualified ileostomized participants was slower than anticipated. We are very grateful to these at-risk participants for being a part of these studies and helping us further the development of SYN-004 for the prevention of CDIs and AAD. The Phase 2a studies are ongoing and we will report topline data from each of them when full data analysis is available. We anticipate results will be consistent with our expectations and the positive PK and safety results demonstrated in the SYN-004 Phase 1a and 1b studies previously reported in March 2015, and in the first four participants in the first Phase 2a previously reported in July 2015.”

SYN-004 Phase 2b Proof-of-Concept Clinical Trial Design

The Phase 2b, parallel-group, double-blind, placebo-controlled study of SYN-004 is expected to enroll approximately 370 patients at up to 75 global clinical sites. Patients age 50 years and older, hospitalized for a lower respiratory tract infection, are expected to be randomized 1:1 into two groups, and receive either SYN-004 or placebo during the standard of care regimen of ceftriaxone (with or without a macrolide). The primary objectives of this clinical trial are to evaluate the effectiveness of SYN-004 to prevent CDIs and CDAD. The secondary objective of this clinical trial is to evaluate the effectiveness of SYN-004 to prevent AAD.

In The News – Synthetic Biologics’ SYN-004 Microbiome-Protecting Preclinical Data Highlighted in Late-Breaking Poster at DDW 2015

syntheticbiologics

Synthetic Biologics, Inc.  a clinical-stage company focused on developing therapeutics to protect the microbiome while targeting pathogen-specific diseases, presented preclinical results in a late-breaking poster at Digestive Disease Week® (DDW) 2015 in Washington, DC today. The research supports the development of SYN-004, the Company’s candidate therapy designed to degrade certain intravenous (IV) beta-lactam antibiotics within the gastrointestinal (GI) tract and maintain the natural balance of the gut microbiome for the prevention of C. difficile infection and antibiotic-associated diarrhea (AAD). Beta-lactam antibiotics are a mainstay in hospital infection management, and include commonly used penicillin and cephalosporin antibiotics, such as ceftriaxone.

The “SYN-004, a Clinical Stage Oral Beta-Lactamase Therapy, Protects the Intestinal Microflora from Antibiotic-Mediated Damage in Humanized Pigs” poster summarized preclinical efficacy data that support the ability of SYN-004 to degrade certain beta-lactam antibiotics in the GI tract, with the following conclusions:

  • In fistulated dogs, oral delivery of SYN-004 resulted in efficient degradation of ceftriaxone in the GI tract, and
  • In humanized pigs, SYN-004 protected the intestinal microflora from ceftriaxone and maintained the natural balance of the microbiome.

“The data suggest that SYN-004 has the potential to protect the human microbiome and to become the first prophylactic therapy designed to prevent antibiotic-mediated microbiome damage, including C. difficile infection, in patients receiving beta-lactam antibiotics,” stated Michael Kaleko, M.D., Ph.D., Senior Vice President, Research & Development of Synthetic Biologics.

“These findings support our ongoing Phase 2a clinical trial that is evaluating the ability of two different dose strengths of SYN-004 to degrade residual IV ceftriaxone in the GI tract of up to 20 healthy participants with functioning ileostomies, without affecting the concentrations of IV ceftriaxone in the bloodstream,” noted Jeffrey Riley, Chief Executive Officer of Synthetic Biologics.

“We are on schedule to report topline data from the Phase 2a clinical trial of SYN-004 this quarter, with a Phase 2b clinical trial anticipated to initiate during the second half of this year.”

The U.S. Centers for Disease Control and Prevention (CDC) has categorized C. difficile as an “urgent public health threat,” and has stated the need for research to better understand the role of normal gut bacteria. SYN-004 is intended to block the unintended harmful effects of certain IV antibiotics within the GI tract and maintain the natural balance of the gut microbiome, potentially preventing the 1.1 million C. difficile infections[i] and 30,000 C. difficile-related deaths[ii] in the United States each year. Approximately 118 million doses of IV beta-lactam antibiotics[iii] that could be inactivated in the GI tract by SYN-004, were administered to approximately 14 million hospitalized U.S. patients during 2012.

The majority of C. difficile cases are caused by the unintended consequences of antibiotic therapy to the gut microbiome. Intravenous (IV) antibiotics excreted to the gut often wipe out the natural balance of microflora, which can lead to recurring diarrhea and perforation of the intestinal wall, with potentially fatal outcomes. Co-administered with IV
antibiotics, Synthetic Biologics’ product candidate, SYN-004, is designed to be a preventive therapy intended to protect the gut microbiome by degrading IV antibiotics, thereby preventing the onset  of  a C. difficile infection.
