Da Volterra is a clinical-stage biotechnology company whose vision is to be a trusted and acknowledged leader in the microbiota field. Da Volterra’s mission is to discover, develop, and bring to market safe and novel therapeutic options, preserving patients’ microbiota to prevent and cure life-threatening diseases. Its most advanced product is DAV132, an oral product to be co-administered with any oral and intravenous antibiotics, to protect patients from antibiotic-induced intestinal microbiota disruption. DAV132 can prevent Clostridioides difficile infection by capturing residual antibiotics in the colon before they can disrupt the intestinal microbiota, without impacting the systemic efficacy of the antibiotics.
We see DAV132 as a real game-changer for C. difficile prevention.
Have a look at the DAV132 webpage, and a video presenting its mechanism of action: https://davolterra.com
The video is highly illustrative of what C. diff. is, how C. diff. is triggered, and how DAV132 could prevent the colonization of the intestinal microbiota by C. diff. and the occurrence of the infection.
Da Volterra has already performed 6 phase 1 clinical trial with DAV132 in healthy volunteers and one phase 2 clinical trial (SHIELD) in patients demonstrating DAV132 favorable safety profile and mechanism of action. The SHIELD study met its primary endpoint: DAV132 was very safe for use in hospitalized patients with several comorbidities and concomitant medications. The study also demonstrated positive results with regards to biological markers of efficacy for prevention of
C. difficile infection: DAV132 effectively protected the intestinal microbiota of patients from antibiotic-induced disruption and DAV132 also prevented the proliferation of C. difficile in an ex vivo assay, suggesting that DAV132 is able to protect patients against antibiotic-induced
C. difficile infection.
The press release on Da Volterra’s phase 2 SHIELD study results is available here: https://davolterra.com/wp-content/uploads/2020/02/2020-02-11-dav132-phase-2-clinical-trial-pr-vf.pdf
Da Volterra is now preparing for the launch of phase 3 pivotal study of DAV132 in patients who have a high risk of developing Clostridioides difficile infection.

"Is another C. diff. infection getting in the way of your life?”
Most Clostridioides difficile (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 disrupt the microbiome by killing both good and bad bacteria. 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 inactive forms (i.e. C diff spores) are untouched. When the microbiome is disrupted, these spores turn into active C diff bacteria and cause disease again and again – usually after antibiotic treatment has finished.
Seres Therapeutics is developing an investigational microbiome drug called SER-109. This medicine is being developed to prevent C diff from coming back by repairing the microbiome. Seres is pleased to announce the positive top-line results from its ECOSPOR-III trial, a Phase 3 trial, reported in August 2020, met its primary endpoint and showed that SER-109 significantly decreased the chance of a recurrence of C. diff in patients who’d had multiple recurrences. Approximately 88% of patients who received SER-109 did not experience a recurrence, compared to approximately 60% of patients who received placebo.
As part of its sustained commitment to patients, Seres may be able to provide access to its investigational drug, SER-109, under certain limited conditions, through its Expanded Access Program (EAP). Seres’ main objective when initiating an EAP is to equitably serve the patient community with compassion and dignity. Seres aims to accomplish this by thoughtfully balancing requests for treatment with the need to protect patient safety and ensure ethical and compliant access to medications.

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 to prevent the regrowth of C. Difficile.
Why bacterial consortia?
Unlike fecal transplants, which require the 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 reductionist 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.
About
CONSORTIUM (NCT03788434) is a randomized, double-blind placebo-controlled Phase 2 study to evaluate the 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 the 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.

Is developing a novel antibiotic known as CRS3123 for treatment of C. difficile infection In preclinical (early) studies CRS3123 has demonstrated that it quickly halts production of C. difficile toxin and spores via a new mechanism of action. In Phase 1 human clinical trials it caused minimal disruption of other, normal gut bacteria. In this Phase 2 study sponsored by NIAID (NIH), Crestone will test two different doses of CRS3123 compared to a standard antibiotic treatment for this infection called vancomycin.
If enrolled, subjects will receive either, 400 mg or 800 mg of CRS3123 or vancomycin for 10 days. Doses will be taken by mouth, every 6 hours. Neither subjects nor study healthcare providers will know which drug is being administered. Then subjects will be followed for an additional 60 days, resulting in about eight outpatient study visits over 70 days. Participants will receive study-related medication and exams at no cost and may be reimbursed for travel expenses for study visits.
The study will enroll subjects 18 or older who have a primary episode or first recurrence of C. difficile infections including diarrhea in the last 24 hours and a positive C. difficile toxin test on a stool sample. They may not participate if they have had more than one C. difficile infection episode in the last three months (or one that was not initially responsive to vancomycin), or two C. difficile infection episodes in the past twelve months. Pregnant or breastfeeding women may not participate in this study, and other entry criteria apply. Study physicians will determine eligibility and then request subjects’ consent to participate.
This study is currently recruiting in the following areas: Sacramento, CA; Lancaster, CA; Calgary, AB CANADA; London, ON CANADA; St. Petersburg, FL; Miami Lakes, FL; Pompano Beach, FL; Miami, FL; Doral, FL; Idaho Falls, ID; Shreveport, LA; Rochester, MN; Omaha, NE; Mentor, OH; Toledo, OH; Uniontown, PA; Union City, TN; San Antonio, TX; Cedar Park, TX; Houston, TX; Seattle, WA.

has developed unique and comprehensive expertise in the field of rare bacteria that it can decipher, culture, and optimize to disclose unsuspected possibilities and induce them to produce biobased molecules with activities of interest on an industrial scale. To do so, DEINOVE has been building and documenting since its creation an unparalleled biodiversity bank that it exploits thanks to a unique technological platform in Europe.
DEINOVE a French biotech company, pioneer in the exploration and exploitation of bacterial biodiversity to address the urgent, global challenge of antibiotic resistance, announced today that the independent Data Safety Monitoring Board (DSMB) has completed its review of the safety data from the first part of the Phase II clinical trial of DNV3837 in the treatment of Clostridioides difficile infection (CDI). The DSMB considered that the benefit/risk balance of antibiotic therapy with DNV3837 was in favor of continuing the recruitment in this trial.
The experience acquired during this first part of the study has made it possible to improve the trial protocol, with a reduction in dose by a factor of 4 and a reduction in the duration of administration by a factor of 2, reducing the intravenous treatment from 12 to 6 hours per day. This improvement simplifies the management of the trial for the investigating physicians and their teams.
The second part of the study will be conducted in an “open-label” manner, as DNV3837 is administered intravenously, while the standards of care are administered orally. Thus, all patients included in the trial (40 in total) will receive DNV3837.
To improve patients inclusion in the trial, it was decided to rapidly open new centers in addition to those active in the United States.
DEINOVE announces a favorable opinion from the DSMB for the continuation of the Phase II clinical trial of DNV3837 in Clostridioides difficile infections

Ridinilazole is being developed by Summit Therapeutics as a potential treatment for C. difficile infection (CDI) and is not approved by any regulatory body. It’s an investigational antibiotic being studied in adolescent patients with CDI. The purpose of the study is to determine whether ridinilazole is safe and effective as compared to the current standard of care. In an earlier clinical trial in patients with CDI, ridinilazole was found to have higher sustained clinical response compared to vancomycin. Sustained clinical response measured the if patients were cured after treatment and whether they experienced a recurrence within 30-days post-treatment.
More information on ridinilazole can be found by visiting
Then click on Our Programs and C. difficile Infection.
Some key information about the trial:
· This trial is expected to enroll approximately 40 adolescent patients (12 to ≤ 18 years of age)
· Patients will be randomized to receive either ridinilazole or vancomycin, and neither the patients nor the study doctors will know which drug patients receive
· Participation will involve about 8 study visits and/or telephone contacts 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 have signs and symptoms of CDI, require CDI treatment, and have ≥ 3 unformed bowel movements in the 24 hours prior to study randomization
· Patients must have presence of free toxin A and/or B in stool
· 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
