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.

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
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/our-programmes/c-difficile-infection.
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
Further details of the global clinical trials can be found by visiting: https://clinicaltrials.gov/ct2/show/NCT03595566 and https://clinicaltrials.gov/ct2/show/NCT03595553, and/or by speaking with one of the clinical trial sites.
The clinical trials will be taking place at sites in the US, Europe, Latin America, Australia and Asia. If you would like to be considered for enrollment into one of the clinical trials, please contact the study site nearest you.
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.
