Synthetic Biologics, Inc. and Enterome Bioscience SA enter into researching effects of beta-lactam antibiotics on the Microbiome

NewsSpeaker

 

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 Enterome Bioscience SA, a pioneer in the development of innovative disease management solutions based on a deep understanding of the gut microbiome, today announced that they have entered into an agreement to conduct metagenomic research on the effects of beta-lactam antibiotics on the gastrointestinal microflora (microbiome) of human patients. As part of this collaboration, a clinical microbiome study of approximately 100 patients is expected to begin next month. Research findings should provide important insights as Synthetic Biologics advances the development of SYN-004, which is intended to protect the gut microbiome from the effects of intravenous (IV) beta-lactam antibiotics, and in particular to prevent C. difficile (C. diff) infections. Phase Ia and Ib clinical trials of Synthetic Biologics’ SYN-004 are scheduled to begin later this year.

The Enterome microbiome study, scheduled for completion in the second half of 2014, is expected to provide a better understanding of the harmful effects of beta-lactam antibiotics on the gut bacterial community. The goal is to establish a “fingerprint” of the damage caused by beta-lactam antibiotics, thus yielding a panel of bacterial biomarkers that can be leveraged for diagnostic purposes. This novel study should clearly define the impact of beta-lactam antibiotics on the natural bacterial diversity of the gut microbiome. Changes in the gut microbiome have been related to multiple diseases, including C. diff infections, antibiotic-associated diarrhea, obesity, diabetes and other metabolic diseases. This study will utilize Enterome’s state-of-the-art shotgun metagenomic sequencing technology to profile the human gut microbiome.

“We are pleased to establish this collaboration with Enterome, a pioneer in the development of biomarkers and therapies for diseases of the gut microbiome,” stated Jeffrey Riley, CEO of Synthetic Biologics. “Findings from this study should support our C. diff therapeutic program, which focuses on protecting and maintaining the balance of bacterial microflora in the gut, while also establishing our presence in Europe.”

Synthetic Biologics’ lead anti-infective product candidate, SYN-004, is the first therapy designed to neutralize IV antibiotics in the gut, and is intended to protect and maintain the balance of bacterial flora in the gastrointestinal tract, to prevent the devastating effects of C. diff. The U.S. Centers for Disease Control and Prevention (CDC) has classified C. diff as an “urgent public health threat”i, surpassing Methicillin-resistant Staphylococcus aureus (MRSA) as the number one hospital-acquired infection in the United States. C. diff is a multidrug-resistant bacterium that infects 1.1 million U.S. patients annuallyii. In the U.S., patients with C. diff are hospitalized an estimated 3.6-7 extra daysiii, costing more than $8.2 billioniv.

“The signing of this agreement with Synthetic Biologics is another important corporate milestone for Enterome. I am very pleased that our pioneering approach to understanding the linkage between changes in the gut microbiome and disease has convinced Synthetic Biologics to work with us on such an important personalized medicine project. It is clear that new diagnostic solutions are needed to properly address the growing problem of antibiotic-induced dysbiosis and associated hospital-acquired bacterial infections,” stated Pierre Belichard, CEO of Enterome. “Tailoring the use of anti-infective treatments based on microbiome profiling is beginning to show great promise as a way to address the management of infectious diseases.”

“Comparing Enterome’s technology to other genomic analyses of gut microbiome is like comparing a Quad Full High definition color resolution TV to resolution of an analog black & white TV,” added Mr. Riley.

About SYN-004 Clinical Development

Synthetic Biologics is developing SYN-004, a novel second generation oral enzyme drug candidate, to be co-administered with commonly used IV beta-lactam antibiotics and is intended to protect the gastrointestinal microflora (microbiome) from the harmful effects of such antibiotics, thus potentially preventing C. diff infections. Planned next steps for SYN-004 include: 1) initiation of a 28-day bridging toxicology study in June 2014; 2) filing of an Investigational New Drug (IND) application to initiate Phase Ia and Ib clinical trials in the second half of 2014, with preliminary topline data expected by year-end 2014; and, 3) initiation of a Phase II efficacy study is expected to begin in the first half of 2015.

C. difficile Prevention Shows Reduction of CDI in NY Hospitals

* In The News 2 June 2014 *

In the past decade, the incidence and severity of hospital acquired Clostridium difficile (CDI) infections has increased dramatically in the United States. Research reported in the Journal for Healthcare Quality (JHQ), however, demonstrates that a collaborative multi-hospital model using standardized clinical infection and environmental cleaning programs can be effective in controlling the spread of this pathogen.

JHQ is the peer-reviewed publication of the National Association for Health Care Quality (NAHQ, http://www.nahq.org).

Treating CDI and its complications costs the U.S. healthcare system more than
$3.2 billion annually, and mortality is now estimated at 23.7 deaths per million. Therefore, interventions that interrupt CDI transmission are a critical component of CDI prevention programs.

The study reported the outcome of a collaborative program in which 35 acute care hospitals in the New York metropolitan area participated in a comprehensive CDI reduction intervention and formed multidisciplinary teams to implement the program.

New York has the highest CDI infection rate in the United States. Participating institutions were almost exclusively teaching hospitals with more than 100 beds. Standardized clinical infection prevention and environmental cleaning protocols were adopted and monitored using checklists.

Outcomes for the program showed that it achieved a significant reduction in the incidence of hospital-onset CDI. Participating hospitals had 1,084 fewer cases of hospital-onset CDI than expected, with a total estimated cost savings of $2.7 million to $6.8 million. This reduction occurred without any interventions intended to alter antimicrobial prescribing practices and without adding extensive new resources.

“Interventions to interrupt and prevent C. diff transmission maybe more successful when implemented on a regional basis, which suggests that community and regional factors, including transferring patients between healthcare facilities, contributes to the epidemiology of C. diff and other healthcare-associated pathogens,” said lead author Brian S. Koll, M.D., chief, infection prevention, Beth Israel Medical Center, New York.

C. difficile; Sanofi Pasteur Announces Favorable Phase II Study Results

Sanofi Pasteur Announces Favorable Phase II Study Results for Investigational Clostridium difficile Vaccine at the American Society for Microbiology Meeting

 

Results indicate vaccine generates an immune response against key toxins
in volunteers and establish dosing for Phase III

Boston, United States of America – May 19, 2014 – Sanofi Pasteur, the vaccines division of Sanofi (EURONEXT: SAN and NYSE: SNY), presented Phase II (H-030-012) trial results for an investigational vaccine for the prevention of Clostridium difficile (C. diff) infection (CDI) at the 114th General Meeting of the American Society for Microbiology (ASM). The Phase II trial met its primary objectives, reactions were generally mild and of short duration, and the candidate vaccine generated an immune response against C. diff toxins A and B. These toxins are largely responsible for CDI, which can cause potentially life-threatening gut inflammation and diarrhea.

 

Based on the Phase II results, a high-dose plus adjuvant vaccine formulation administered on days 0, 7 and 30 was selected for further evaluation in the global efficacy program Cdiffense. This ongoing Phase III trial began in August 2013 with plans to include up to 200 sites in 17 countries.

 

C. diff infection threatens the many people who frequently use antibiotics, as well as older hospitalized patients and residents in long-term healthcare facilities,” said Jamshid Saleh, M.D., who participated in Phase II and is currently the principal investigator in the Phase III trial at Northern California Clinical Research Center in Redding, California. “It would be great if we could offer patients a way to help prevent this contagious and debilitating disease versus just treating it after it happens.

 

The Phase II vaccine study was a randomized, multi-center trial split into two stages. The first, conducted with 455 volunteers, was placebo-controlled, double-blind and designed for dose and formulation selection. The second, which included 206 additional volunteers, was designed to compare the dose and formulation chosen in the first stage against two alternate dosing schedules. Volunteers in the study were adults aged 40-75 years who were at risk of CDI due to impending hospitalization or residence in a long-term healthcare facility.

 

In this trial, we saw a significant increase in antibody production against C. diff toxins, across all dosing schedules and volunteer ages,” said Guy De Bruyn, MBBCh MPH, Director, Clinical Development, Sanofi Pasteur, who presented the data at ASM. “These results provide a strong foundation for our efforts to develop and offer a vaccine to prevent first occurrence CDI.

 

In Stage 1 of this trial, volunteers were randomized into one of five study groups: high-dose or low-dose vaccine either with or without adjuvant, or placebo. Each formulation was administered on days 0, 7 and 30. Immune responses were measured using both Enzyme Linked Immunosorbent Assay (ELISA), which assesses anti-toxin A and B immunoglobulin G (IgG) concentrations, and Toxin Neutralization Activity (TNA), which measures anti-toxin A and B neutralizing activity. Composite ELISA ranking analysis determined that the high-dose plus adjuvant vaccine formulation (Group 3) generated the greatest immune response over a 60-day period. ELISA results also showed four-fold increases in the development of detectable antibodies for both toxins A and B.

 

The high-dose plus adjuvant vaccine formulation was then selected for further study in Stage 2 of the trial, which compared its use across three schedules: days 0, 7 and 30 (Group 3, N=101); days 0, 7 and 180 (Group 6, N=103); and days 0, 30 and 180 (Group 7, N=103). Analysis was conducted on days 0, 7, 14, 30, 60, 180 and 210.

 

Increased immune responses were observed in all vaccine groups and with each dose, according to ELISA and TNA. Overall, Group 3 demonstrated the most favorable immune profile over the 30-, 60- and 180-day periods, particularly in volunteers aged 65-75 years.

 

The safety profile of all vaccine doses was deemed acceptable throughout the Phase II study. Reactions were monitored until day 210 and were generally Grade 1 (classified as mild), of short duration, did not lead to study discontinuations, and were not considered clinically significant.

 

Sanofi Pasteur’s investigational vaccine stimulates a person’s immune system to fight C. diff toxins upon exposure and, ultimately, may help prevent a future CDI from occurring,” said Dr. Saleh. “Like other toxoid vaccinessuch as tetanus, diphtheria and whooping coughthis investigational vaccine targets the symptom-causing toxins generated by C. diff bacteria and could be an important public health measure to help protect individuals from CDI.

 

Analysis of available data indicates that CDI may have resulted in up to $4.8 billion in excess costs in acute-care facilities in the United States (U.S.) during 2008.4 In 2009, U.S. hospital stays in which CDI was a principal diagnosis averaged 6.9 days and $10,100.When CDI was a complicating factor to already complex principal diagnoses (e.g., septicemia, pneumonia, congestive heart failure, renal failure), hospital stays more than doubled and costs more than tripled (16 days and $31,500, respectively).5

C. difficile infection - Prevention - Da Volterra presents promising results of DAV-132 compound

* In The News 13 May 2014 *

Da Volterra, a leading biopharmaceutical company in the field of bacterial resistance, announces today very promising new results about DAV132 in the prevention of the side effects of antibiotics and the occurrence of severe Clostridium difficile infections. The Company presents two posters at ECCMID 2014 (the European Conference of Microbiology and Infectious Diseases) taking place in Barcelona on May 10-13, 2014.

With a novel and unique mechanism of action, DAV132 is a product candidate aiming at protecting the intestinal flora from the side effects of administered antibiotics, hence preventing Clostridium difficile infections. This pathogenic bacterium causes serious and potentially lethal gastro-intestinal infections. To this end, DAV132 captures the antibiotic residues in the digestive tract which are at the origin of the alterations of the intestinal flora, while maintaining the efficacy of the antibiotic treatment. As a consequence the flora disruption adverse effect is avoided.

The CL1001 study, a phase I clinical trial performed in the spring 2013 at the Medicine University of Greifswald (Germany) with 18 healthy volunteers, showed the expected targeted delivery of DAV132. The results demonstrate that DAV132 effectively exerts its adsorbing effect in the ileum and the colon, whereas DAV132 does not interfere upstream with antibiotics in the small intestine. Antibiotic treatments given together with DAV132 would thus be optimized, DAV132 reducing the alterations of the flora and their consequences such as Clostridium difficile infections or the emergence of resistant bacteria.

A preclinical study performed in the reference hamster model of Clostridium difficile infections evidenced the preventive effect of DAV132. Animals treated with moxifloxacin only (an antibiotic) showed 100% mortality (no survivor after 7 days) in the experiment. Interestingly, animals treated with moxifloxacin and DAV132 during 5 days are protected from the lethal impacts of Clostridium difficile. The protective effect of DAV132 is dose-dependent and a total protection is reached at the highest doses. This study in a predictive model of the disease illustrates the protective effects of DAV132, co-administered with an antibiotic treatment, against Clostridium difficile infections.

The detailed results are presented in two posters at the ECCMID conference (European Congress of Clinical Microbiology and Infectious Diseases) taking place in Barcelona on the 10-13 May, 2014.

Florence Séjourné, CEO of Da Volterra, declared: We are particularly proud to present these results to the scientific community, illustrating the very innovative and unique profile of DAV132. The control of Clostridium difficile infections and antibiotic resistance are major public health challenges. We look forward to advancing the development of DAV132, and are convinced that Da Volterra is well positioned to push forward its innovative product pipeline to meet these urgent medical needs.
