Clinical Studies Are In Progress To
Help Them — Help You — Help Others ♥
Here is a list of Clinical Trial Phases:
Clinical trials are conducted in a series of steps, called phases – each phase is designed to answer a separate research question.
- Phase I: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
- Phase II: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
- Phase III: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
- Phase IV: Studies are done after the drug or treatment has been marketed to gather information on the drug’s effect in various populations and any side effects associated with long-term use.

C. diff. Infection (CDI)_Prevention Clincal Studies In Progress
UPDATE: On May 11, 2017 The U.S. Food and Drug Administration (FDA) has granted a Breakthrough Therapy Designation for SYN-004 (ribaxamase) for the prevention of Clostridium difficile infection.
Synthetic Biologics is developing cutting-edge therapeutics to treat pathogen-specific diseases.
Our two leading candidates are:
SYN-004 (ribaxamase) to prevent C. difficile infection and antibiotic-associated diarrhea
SYN-010 to treat irritable bowel syndrome with constipation (IBS-C)
A global, multi-center, randomized, double-blind, placebo-controlled clinical trial to evaluate the ability of SYN-004 to degrade certain IV beta-lactam antibiotics within the GI tract to maintain the natural balance of the gut microbiome for the prevention of C. difficile infection, C. difficile associated diarrhea and antibiotic-associated diarrhea in patients hospitalized for a lower respiratory tract infection and receiving IV ceftriaxone.
Update July 2016:
the United States Adopted Names Council (USAN) of the American Medical Association has approved the use of “ribaxamase” (Rye-bak’-sa-mase) for Synthetic Biologics’ SYN-004. Ribaxamase is the Company’s Phase 2 development candidate designed to protect the gut microbiome from the unintended effects of certain commonly used intravenous (IV) beta-lactam antibiotics for the prevention of C. difficile infection (CDI), antibiotic-associated diarrhea (AAD) and the emergence of antibiotic-resistant organisms.
Synthetic Biologics recently reported positive results from two Phase 2a clinical trials demonstrating a correlation of the 150 mg dose of ribaxamase with the degradation of residual IV ceftriaxone alone, and in the presence of the proton pump inhibitor (PPI), esomeprazole, to levels that were near or below detectable in the intestinal chyme of healthy participants with functioning ileostomies. A Phase 2b proof-of-concept, randomized, placebo-controlled clinical trial is currently underway to evaluate the ability of ribaxamase to prevent CDI and AAD in patients hospitalized with a lower respiratory tract infection and receiving IV ceftriaxone. An interim analysis of blinded data performed by an independent data monitoring committee is expected in summer of 2016.
“The approval of the generic name ribaxamase for SYN-004 by USAN is a defining milestone for Synthetic Biologics. Ribaxamase represents a newly created and innovative first-in-class drug designed to protect the naturally occurring gut microbiome from the unintended consequences of antibiotic use,” said Jeffrey Riley, President and Chief Executive Officer. “By degrading certain IV beta-lactam antibiotics before they reach the gastrointestinal (GI) tract, ribaxamase may not only prevent the onset of CDI and AAD, but has the potential to be an instrumental tool for preventing the emergence of antibiotic resistance in organisms which comprise the gut microbiome. We are excited for the continued clinical development of ribaxamase and look forward to sharing our progress including announcing results from our ongoing global Phase 2b proof-of-concept clinical trial.”
Da Volterra is a biopharmaceutical company, privately-held and headquartered in Paris (France), focused on the discovery and development of innovative therapeutic and preventive products for Clostridium difficile and multi-resistant infections. Our most advanced product, DAV132, is designed as a prophylactic treatment intended to prevent the development of
C. difficile infection, by binding with and neutralizing common antibiotics in the gut.
DAV132 decreases the risk of triggering CDI by inactivating residual antibiotics in the colon
before they can disrupt the bacterial flora, without impacting the systemic efficacy of the antibiotics.
It is noteworthy that DAV132 is developed to accompany all oral and intravenous antibiotics of any class and would therefore significantly reduce the risks to acquire C.difficile infections for patients at risk (especially patients who had prior episodes). We see DAV132 as a real game changer for C.difficile prevention.
Have a look at our video presenting the mechanism of action of DAV132:
The video is highly illustrative of what C.diff is and how C.diff is triggered.
We have already performed 2 clinical trials with DAV132 and we have a very exciting dataset (both preclinical and clinical) suggesting that DAV132 will very effectively prevent C.diff infections. I would be happy to exchange with you more information on this. Our next clinical trial, in patients actually treated with antibiotics and at-risk of C.diff, will start in Q4 2015 or early 2016
Pfizer Announces Positive Top-Line Results from Phase 2 Study of
Investigational Clostridium difficile Vaccine for the
Pfizer’s C. difficile Vaccine Candidate to Commence Phase 3 Study in First Half of 2017
On Thursday, January 26, 2017 Pfizer Inc. announced that the Phase 2 study evaluating the Company’s Clostridium difficile (C. difficile) vaccine candidate, PF-06425090, provided positive data, based on a pre-planned interim analysis. The randomized Phase 2 study (NCT02561195) examined the safety, tolerability, and immunogenicity of the vaccine in healthy adults 65 to 85 years of age. Pfizer’s vaccine candidate is designed to help prevent
C. difficile infection (CDI), which can include life-threatening diarrhea and pseudomembranous colitis,1 by inducing a functional antibody response capable of neutralizing the two main disease-causing toxins produced by C. difficile (toxins A and B).2
“Despite improved infection control measures, C. difficile disease continues to rise, further augmenting an already urgent public health threat with particular negative impact on older adults,” said Kathrin Jansen, Ph.D., senior vice president and head of Vaccine Research and Development for Pfizer Inc. “We are very encouraged by these interim immunogenicity and safety results demonstrating robust increases in vaccine-elicited neutralizing antibodies to both toxins, that we believe could provide protection against C. difficile disease.”

Seres Therapeutics is developing Ecobiotic® drugs designed to prevent C diff infections from coming back again.
Most C diff infections occur after antibiotic treatment. Why? Our gut contains trillions of microbes, called the microbiome, which protects us from bacterial invaders that can cause disease. Antibiotics kill both good and bad bacteria, leaving holes in this ecology (community) of microbes. When the microbiome is damaged, bad bacteria, like C diff, can take advantage and cause disease. Although specific antibiotics can kill the active C diff bacteria, the sleeping forms (ie, spores) are untouched. These spores turn into active C diff bacteria and cause disease again and again – usually after antibiotic treatment has finished.
Seres Therapeutics has developed an oral medicine called SER-109, which aims to prevent C diff from coming back by repairing the microbiome. This Ecobiotic® drug is being studied in a large Phase 3 clinical trial that is enrolling patients who have had multiple C diff infections. This important clinical study is being done in the United States and Canada and may provide the final clinical data needed to support FDA and Canadian drug approvals. For more information, please follow this link to the patient website: https://serescdiffstudy.com/
Seres Therapeutics is also enrolling patients into a phase 1b trial of SER-262, which is an Ecobiotic® drug to prevent recurrence among those experiencing their first C diff infection.

Valneva Announces Start of Phase II Clinical Trial of its Clostridium difficile vaccine candidate
UPDATE: Valneva SE July 26, 2016 announced the successful completion of its Phase II study for its prophylactic vaccine candidate VLA84 targeting primary prevention of C. difficile infection (CDI), which is emerging as a leading cause of life-threatening, healthcare-associated infections (HAIs) worldwide. Valneva previously announced positive top-line data from the Phase II study at the end of 2015. These initial results, which included data up to Day 56 following initial vaccination, were presented at the American Society of Microbiology’s annual meeting, ASM Microbe 2016, on June 17 in Boston. VLA84 was immunogenic at all doses and formulations tested, in that Immunoglobulin G (IgG) and functional (neutralizing) antibody responses were observed. The study met its primary endpoint in terms of identifying the dose/formulation with the highest seroconversion rate against both toxins A and B and confirmed the favorable safety profile observed in Phase I.
Final Phase II results included the follow-up of study participants until Day 210. This long-term data confirmed the optimal vaccine dose and formulation that had been previously identified (high-dose formulation without adjuvant) with an immunogenicity profile at Day 210 in line with expectations. Long-term safety concerns were not seen in any of the different vaccine doses tested.
- First Study participant(s) enrolled in Phase II trial which aims to enable Phase III entry upon successful completion
- Study to enroll 500 healthy subjects aged 50 years and older in the United States and Germany
- First results are expected in Q4 2015
Lyon (France), December 18, 2014 – European biotechnology company Valneva SE (“Valneva”) announced today the initiation of the Phase II clinical trial of its VLA84 prophylactic vaccine candidate against Clostridium difficile (C. difficile), the main cause of nosocomial diarrhea. Data from the Phase I study in healthy elderly and adults showed good safety and immunogenicity of the vaccine candidate, and indicated functionality of induced antibodies, supporting the Company`s decision to progress the vaccine
candidate into Phase II
C. diff. Infection (CDI) Treatments Clinical Studies In Progress
To LISTEN to the October 2017 Live Broadcast from the C. diff. Spores and More Global Broadcasting Network program with Dr. Richard Vickers, and Dr. Dr Kevin W Garey, PharmD, Click on the Summit Therapeutics Logo above : Research Update From Summit Therapeutics on Ridinilazole
With input from the FDA and EMA, Summit intends to design the Phase 3 clinical programme to evaluate superiority of ridinilazole over standard of care in the treatment of C. diffiicle Infection (CDI).
A positive Phase 3 result on superiority has the potential to support the commercial launch of ridinilazole as a differentiated therapy that can both treat initial CDI and reduce disease recurrence.
Mr Glyn Edwards, Chief Executive Officer of Summit commented: “The constructive end of Phase 2 meetings with the US and European regulators have enabled us to design a Phase 3 programme that focuses on evaluating ridinilazole’s superiority over standard of care.
This is something we believe would help differentiate our novel class antibiotic from currently marketed CDI treatments and those in late-stage development. Superiority in the combined measure of treatment of initial infection and importantly, reduction in recurrence, could position ridinilazole for front-line treatment of CDI.”
Summit discussed its Phase 3 development programme with the FDA at an End of Phase 2 meeting and through a scientific advice process with EMA. With input from both agencies, the Phase 3 programme is expected to include two trials evaluating ridinilazole as compared to the standard of care, vancomycin, each of which would enrol approximately 700 patients with CDI with the primary endpoint being superiority in sustained clinical response (‘SCR’). Other planned endpoints will include health economic outcome measures. The Phase 3 trial designs are consistent with the successful proof of concept Phase 2 trial, CoDIFy, in which ridinilazole achieved statistical superiority over vancomycin in SCR. SCR is a combined endpoint that measures cure at the end of treatment and a lack of recurrence in the 30 days after treatment. FDA also confirmed that ridinilazole would be eligible for Priority Review based on its QIDP designation.
During the trial, the new oral antibiotic significantly outperformed vancomycin, the current standard prescription, which was the primary objective said Summit.
Over two-thirds (66.7%) of those treated showed a sustained clinical response (SCR) against 42.4% for vancomycin.
The statistical superiority was driven by a large numerical reduction in recurrent disease compared with vancomycin, which Summit said was key as recurrence is one of the hardest things to stop.
C.difficile or CDI is a growing danger for patients in hospital, care homes and the wider community.
Annually, there are between 450,000 and 700,000 cases in the US alone, with the elderly and sick especially vulnerable.
One study has suggested it costs US $4.8bn to treat these people.
The biggest unmet need in CDI treatment is reduce recurring cases, he added and the results from the latest trial had exceeded its ‘wildest expectations’.
“These outstanding clinical data from CoDIFy strongly support the profile of ridinilazole as a narrow spectrum antibiotic.
“There is a vital need for potent new antibiotics, and the potential of ridinilazole has attracted great interest.
Edwards added that the results from the CoDIFy trial were exceptionally encouraging and the aim no is to advance ridinilazole into Phase 3 clinical trials.
Here, the company would evaluate partnership opportunities against the benefit of it forward itself, he added.
Professor Mark Wilcox, at Leeds University and Public Health England’s lead consultant on C.difficile added that the latest data indicated ridinilazole could become an important new treatment option for CDI with the potential to reduce the high rates of recurrent disease that remain a key clinical challenge.
CoDIFy was a double blind, randomised, active controlled, multicentre, Phase II clinical trial that evaluated the efficacy of ridinilazole against vancomycin in 100 patients in the US and Canada.
Results from a second CoFIFy trail are due next year, though Edwards said the results announced today would provide the bulk of the quantitative data.
ridinilazole has already received Qualified Infectious Disease Product, or QIDP, designation and has been granted Fast Track status from the US Food and Drug Administration

Study: PUNCH CD 3 (Currently Enrolling) *Updated 9/2018
The PUNCH CD 3 study is a Phase 3 clinical study to evaluate the safety and efficacy of Rebiotix RBX2660 for the prevention of recurrent Clostridium difficile infection (CDI).
This prospective, randomized, double-blinded, placebo-controlled clinical research study is expected to enroll up to 270 patients at 60 research sites in the U.S. and Canada. Patients that meet the study requirements and choose to enroll will be randomized to receive either RBX2660, an investigational new drug, or a placebo. Two out of every three study patients will receive RBX2660, and one out of every three study patients will receive the placebo study treatment (2:1 randomization). Study patients whose CDI returns within 8 weeks after blinded study treatment may be scheduled to receive an RBX2660 treatment (no placebo). The study’s primary endpoint will compare the proportion of patients with treatment success following treatment with RBX2660 to prevent recurrent CDI within 8 weeks of blinded treatment as compared to placebo.
