Clinical Studies Are In Progress To
Help Them — Help You — Help Others ♥
Here is a partial-listing and explanations 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.
THE FOLLOWING ARE A FEW EXAMPLES OF CLINICAL TRIALS AVAILABLE ADDRESSING C.difficile INFECTION PREVENTION AND TREATMENTS.

C. diff. Infection (CDI)_Prevention Clinical Studies
Da Volterra is a is a clinical stage biotechnology company whose vision is to be a trusted and acknowledged leader in the microbiota field. Our mission is to discover, develop and bring to market safe and novel therapeutic options, preserving patients’ microbiota to prevent and cure life-threatening diseases. Our most advanced product is DAV132, an oral product to be co-administered with any antibiotics, in order to protect patients from antibiotic-induced intestinal microbiota disruption. DAV132 decreases the risk of triggering Clostridium difficile infection 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. We see DAV132 as a real game changer for C.difficile prevention.
Have a look at DAV132 webpage and video presenting its mechanism of action: https://davolterra.com
The video is highly illustrative of what C.diff is and how C.diff is triggered.
We have already performed 4 clinical trials with DAV132 in healthy volunteers and we have a very exciting dataset (both preclinical and clinical) suggesting that DAV132 will very effectively prevent C.diff infections. We are currently conducting a clinical trial, in patients actually treated with antibiotics and at-risk of C.diff.

“Is another C. diff. infection getting in the way of your life?”
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.

Vedanta Biosciences, Inc. is a clinical-stage microbiome company developing a new category of therapies for immune-mediated diseases based on rationally-defined consortia of human microbiome-derived bacteria.
VE303 is a defined bacterial consortium designed to prevent recurrent C. difficile infections (“CDI”). VE303 is a preparation of eight different bacteria that were selected for their presumed ability of preventing regrowth of C. Difficile.
Why bacterial consortia?
Unlike fecal transplants, which require use of donors’ stool and are an inherently variable procedure, bacterial consortia therapeutics are defined drug compositions produced from clonally isolated bacteria that can trigger targeted immune responses. And unlike reductionistic approaches such as single strain probiotics, they can robustly shift the gut ecosystem.
The results of the Phase 1 study of VE303 showed both rapid expansion of protective VE303 bacteria in the gut and accelerated recovery to a healthy microbiome after disruption to the normal microbiome in the gut caused by antibiotics. Based on these Phase 1 results, Vedanta is now evaluating VE303 (the “CONSORTIUM” study) in individuals with CDI to see if it can prevent future CDI recurrences by restoring the intestinal bacteria to a healthy state.
CONSORTIUM (NCT03788434) is a randomized, double-blind placebo-controlled Phase 2 study to evaluate safety, tolerability, pharmacokinetic/pharmacodynamic (PK/PD) and efficacy of VE303 in patients with a recent diagnosis of CDI, who have completed a course of antibiotics but remain at risk for recurrence. The primary endpoint will be prevention of infection recurrence at eight weeks.
CONSORTIUM is currently enrolling participants across North America (U.S. and Canada) who have been diagnosed with high-risk CDI.

Valneva Clinical Trial of its Clostridium difficile vaccine candidate
UPDATE: February 2019
Valneva’s Clostridium difficile vaccine candidate – VLA84
Valneva successfully completed Phase 2 development of its prophylactic vaccine candidate against Clostridium difficile infection, confirming previously announced positive topline data. The vaccine candidate VLA84 is Phase 3 ready.
Valneva seeks to partner its Clostridium difficile vaccine candidate. At this point, however, potential partners are hesitant about the level of investment required to fund a Phase 3 clinical trial. Therefore, the Company reviewed its development and partnering approach. Valneva will consider using the first CDI vaccine approval and to conduct a head to head, non-inferiority Phase 3 trial, based on an immunological correlate that is expected to substantially improve the investment – risk profile of an in-house, or partnered, development to market.
BACKGROUND: 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
Acurx Pharmaceuticals, LLC a privately held, clinical-stage, a biopharmaceutical company developing new antibiotics for difficult-to-treat bacterial infections, announced that its lead product candidate, ACX-362E, has successfully completed the 68-subject, double-blind, placebo-controlled, multiple-ascending dose Phase 1 clinical trial of ACX-362E in healthy volunteers. The Phase 1 clinical trial was first-in-man for a new class of antibiotics that work by inhibiting DNA synthesis in certain bacterial cells (pol IIIC inhibitors). Pol IIIC is required for DNA replication of many Gram-positive pathogens, including Clostridioides as well as Enterococcus, Staphylococcus, and Streptococcus. Multiple-dose levels up to 450 mg BID for 10 days were shown to be well tolerated. Any adverse events attributed to ACX-362E were mild, transitory, and did not interrupt treatment in any subject. Blood levels of ACX-362E show low systemic exposure, indicating poor oral absorption and desirable in treating CDI. Additionally, fecal concentrations of ACX-362E at higher dose levels rapidly exceeded the concentrations known to inhibit C. difficile by several hundred-fold and were sustained for the duration of the 10-day treatment period.
ACX-362E is a novel, oral antibacterial agent for the treatment of Clostridioides difficile infection (CDI), an acute, serious, potentially life-threatening, intestinal infection. This Phase 1 study included a 6-subject vancomycin treatment arm (the current standard of care for CDI) for comparative microbiome analysis by Dr. Kevin Garey, Professor, University of Houston College of Pharmacy and Principal Investigator for this aspect of the trial. ACX-362E effects on the fecal microbiome were compared to those produced by vancomycin over the 10-day treatment course. The results demonstrate that while vancomycin significantly disrupts Bacteroidetes and Firmicutes, deemed to constitute more than 80% of the favorable microbiota in the gastrointestinal tract, ACX-362E had minimal impact on the Bacteroidetes and Firmicutes. Specifically, vancomycin treatment resulted in a 3-4 log reduction in Bacteroides while ACX-362E doses of 300 or 450 mg BID showed minimal effect.
Safety information was analyzed through assessment of adverse events and other standard safety measures, while concentrations of ACX-362E were determined in both the blood and the feces, the latter being the critical site of drug delivery for treating CDI. In addition, Acurx partnered with Dr. Kevin Garey’s laboratory at the University of Houston to perform state-of-the-art microbiome testing of gastrointestinal flora in trial subjects.

Summit Therapeutics Ridinilazole is being developed by Summit Therapeutics as a potential treatment for
C. difficile infection (CDI). It’s a new antibiotic, and Summit is testing whether it can improve patient outcomes over the current standard of care, vancomycin, in two global clinical trials. In an earlier clinical trial in patients with CDI, ridinilazole was found to be superior to vancomycin in a measure called sustained clinical response, which tested if patients were cured after treatment and did not experience a recurrence within 30-days post-treatment. More information on ridinilazole can be found by visiting www.summitplc.com
Some key information about the trials:
- Each trial is expected to enroll up to 680 patients
- Patients will be randomized to receive either ridinilazole or vancomycin, and neither the patients nor the study doctors will know which drug they receive
- Participation will involve about 7 study visits over approximately 100 days to track the safety and effectiveness of each drug
- Patients who participate may be reimbursed for travel expenses associated with study site visits
- Patients must be 18 years of age or older
- Patients must have signs and symptoms of CDI, including diarrhea, in the 24 hours prior to entry in the trial and a positive toxin test on a stool sample produced within 72 hours of entry into the trial
- Patients cannot have had more than one prior episode of CDI in the previous three months or more than three episodes in the past 12 months
- Patients cannot have had more than 24 hours of CDI antibiotic treatment prior to entry into the trial
- There are additional entry criteria and considerations; the study doctors will ultimately decide whether a patient is eligible for entry into the clinical trials and the patient will be required to give consent

This clinical trial (CP101) is in Phase 2. For more information from
http://www.ClinicalTrials.gov click on the following link:
The study drug, CP101, is a Full-Spectrum Microbiota™ investigational drug designed to deliver bacteria to the intestine. This bacteria may help overtake the surplus of C. diff. bacteria that cause CDI.
CP101 is encapsulated for oral administration. The powder is intended to be released from the capsules in the right part of your intestine where the bacteria may repopulate. This may aid in restoring the diverse community of bacteria found in the healthy human gut, which may prevent recurrence of C. diff..
CP101 drug products are in development and investigational at this time. No product has yet been approved by the U.S. Food and Drug Administration. Prolacta Bioscience is a company dedicated to Advancing the Science of Human Milk. It has been leading the way in developing human milk-based nutritional products for premature and other infants with special nutritional needs since 2005.
Prolacta has recently developed a potential therapeutic, consisting of beneficial components derived from human milk and is investigating its usefulness in the treatment of C. difficile associated diarrhea. In a healthy individual, the bacteria population living in the gut (microbiome) provides many health benefits and can prevent pathogens from causing infections. Antibiotics wipe out the beneficial bacteria in the gut and can allow harmful bacteria such as C. difficile to overgrow.
C. difficile causes disease by producing toxins that injure the cells of the gut wall. Although some specific antibiotics can cure C. difficile infections, at times the pathogen can resist antibiotics by forming spores. These C. difficile spores are immune to the effects of antibiotics and, under certain conditions, can become harmful active bacteria, which start the disease cycle all over again. If the gut microbiome does not return to a healthy state, the C. difficile infection may still return after each antibiotic treatment.
Prolacta’s new product has natural biological activities that could help restore the individual’s healthy gut microbiome and support immune function in order to potentially reduce the risk of a relapse of C. difficile disease without having to introduce a new bacterial population collected from outside sources.
Some Key Information about the trial:
• Patients will be given liquid product (consisting of human milk-derived components) or placebo, administered orally three times daily for seven days
• Phase I Study
• Double-blind, randomized, placebo-controlled dose escalation trial
• Study subjects will receive one of three doses depending upon which dose group is recruiting at the time of their participation.
• Currently enrolling patients age 18 or older who have had no more than four prior occurrences of C. difficile associated diarrhea (CDAD) and are currently being treated with standard of care antibiotics.
• The target enrollment number is between 48 and 54.
