197 Clinical Trials for Various Conditions
The overall objective of the RESTORATiVE303 study is to evaluate the safety and the Clostridioides difficile infection (CDI) recurrence rate at Week 8 in participants who receive a 14-day course of VE303 or matching placebo. The objectives and endpoints are identical for Stage 1 (recurrent CDI) and Stage 2 (high-risk primary CDI).
This trial will be initiated to explore whether RBX2660 (REBYOTA®) could be suitable for administration by the practice of colonoscopy. More specifically, the purpose of this trial is to explore the safety and clinical effectiveness of RBX2660 when delivered by colonoscopy to adults with rCDI. The experience of physicians will be documented through a physician-experience questionnaire to explore the usability of RBX2660 in clinical practice for colonoscopic administration. Furthermore, to explore the patient-experience of RBX2660 treatment, each trial participant will be offered to undergo a structured interview.
The purpose of this study is to determine whether a single strain capsulated probiotic, when used after standard C. difficile antibiotic therapy, is effective in reducing the risk of infection recurrence mediated by a decrease in colonization by toxigenic C. difficile. This study will include adults with a history of two episodes of C. difficile infection (CDI).
The primary objective of the study is to determine whether dietary intervention to increase fiber and decrease fat reduces C. difficile infection recurrence in a cohort of oncology patients.
This is a randomized, placebo-controlled, double-blind, multi-site study in which up to approximately 36 subjects with a recent C. difficile infection (CDI) who have completed a standard of care course of CDI antibiotics and have achieved clinical cure based on signs and symptoms, will be randomized to 7 or 28 daily doses of ART24 or placebo. Subjects will be followed for 6 months after the last dose of study drug.
The study will compare the effectiveness of Bezlotoxumab in individuals with active C. diff ( Clostridium difficile) infection who are diagnosed with Inflammatory Bowel Disease.
This is a retrospective case:control study examining the use of adjunctive bezlotoxumab to standard C. difficile infection (CDI) treatment compared to standard CDI treatment alone in patients with CDI seen in an academic medical center's specialty outpatient clinic.

This is a single center collection of discarded biological samples and electronic medical review (EMR) data on patients who are hospitalized with clostridium difficile infections and treated with Fidaxomicin
Clostridium difficile (C. difficile) is a major pathogen causing serious healthcare-associated diarrheal illness in patients. Prevention of healthcare facility-onset C. difficile infection (CDI) is essential. Many CDI cases are caused by the transmission of the pathogen from patients who carry the bacteria, but do not have symptoms. However, there are limited data on how to prevent the transmission of C. difficile from patients who do not have symptoms. Universal gloving practices - the use of gloves by all healthcare workers for all patient contacts - may reduce CDI cases. In this study, the investigators will examine the effectiveness of universal gloving practices as compared to standard of care (use of gloving for contact only in patients with known CDI or other infections). The investigators will compare the effects of these practices on the transmission of C. difficile within participating hospital units to determine if universal gloving is an effective practice to prevent healthcare-associated CDI.
The purpose of this study is to gain further knowledge regarding the effectiveness of vancomycin prophylaxis in preventing Clostridium difficile infections in order to guide physicians' practices.
This is an open-label study to evaluate the safety, efficacy, and PK of DNV3837 at a dose of 1.5 mg/kg actual body weight(BW)/day administered via IV infusion in subjects with CDI. The study will be conducted in 2 subsequent parts. In Part 1 of the study, 10 subjects of either sex with severe or non-severe CDI will be enrolled to receive DNV3837. In Part 2 of the study, up to 30 subjects with severe or non-severe CDI will be enrolled to receive DNV3837. In both parts of the study, treatment infusions will be administered at a constant rate resulting in a total IV infusion duration of 6 hours per day, for a total maximum daily dose of 120 mg DNV3837. Infusions will be administered once daily for 10 consecutive days. The objectives of the study are: * To evaluate the safety of intravenous (IV) DNV3837; * To evaluate the efficacy of IV DNV3837; * To assess the pharmacokinetics (PK) of DNV3837 and DNV3681 in plasma and of DNV3681 in urine and feces; * To assess C. difficile using microbiological assessments; * To assess the proportion of subjects colonized with vancomycin-resistant enterococci (VRE), extended-spectrum beta-lactamase (ESBL) organisms, or carbapenem-resistant Enterobacteriaceae (CRE) in feces; and * To assess changes in the fecal microbiome using 16S ribosomal ribonucleic acid (RNA) analysis
This is a randomized, open label, comparative, Phase II study to determine which dose of fecal microbiota transplant using Penn Microbiome Therapy (PMT) products is most effective in treating and preventing recurrence of Clostridium difficile infection (C diff).
This is a randomized, open label, comparative, Phase II study to determine whether fecal microbiota transplant using Penn Microbiome Therapy products helps standard therapy to treat severe Clostridium difficile infection (C diff).
This is a prospective, multicenter, open-label Phase 3 study of a microbiota suspension of intestinal microbes. Patients who have had at least one recurrence of CDI after a primary episode and have completed at least one round of standard-of-care oral antibiotic therapy or have had at least two episodes of severe CDI resulting in hospitalization may be eligible for the study. Subjects may receive a second RBX2660 enema if they are deemed treatment failures following the initial enema per the protocol-specified treatment failure definition.
The investigators are doing this research study to answer questions about a nutritional therapy called the Specific Carbohydrate Diet (SCD) for children with active Clostridium Difficile Infection. For this study, the investigators will be looking to determine: 1. Is SCD effective for the treatment for Clostridium Difficile Colonization? 2. Is the SCD well tolerated?
This study will investigate a Clostridium difficile vaccine in adults 50 years of age and older. In half the adults, all 3 doses given are the Clostridium difficile vaccine, and in half the adults, 2 of the 3 doses are the Clostridium difficile vaccine with the other dose containing no active ingredients. The study will look at the subjects' immune response to the vaccine and assess the safety and tolerability of a 2-dose regimen of Clostridium difficile vaccine compared to a 3-dose regimen of Clostridium difficile vaccine.
This is a research study to collect information from people that have Clostridium difficile infection (CDI) and are treated with a standard antibiotic treatment in which the antibiotic dose is gradually reduced over 6 weeks and bezlotoxumab (BEZLO), an approved monoclonal antibody targeting C. difficile toxin, which has shown to reduce CID recurrence when used in combination with standard antibiotic treatment.
This study evaluated the safety and efficacy of VE303 for participants with primary C. difficile infection (pCDI) at high risk for recurrence or subjects with recurrent C. difficile infections (rCDI).
A total of 440 patients meeting enrollment criteria with a primary episode of C. Difficile Infection (CDI) will be enrolled across 3 sites. The total study time period for study procedures followed by clinical monitoring is anticipated to be about 24 months (biomarker assays and other analyses may be completed after the 24 month time period). All participants will receive oral antibiotics for CDI under the care of their physician. After consenting to participate in the study, participants will be randomized to receive either misoprostol (200 mcg po BID) or matching placebo for 14 days. Participants will be monitored for a total time-period of approximately 9 weeks with the goal of monitoring for recurrence of CDI during an 8-week follow-up period from the time that the course of antibiotic treatment is completed. Patients will have blood and stool samples (or rectal swabs if participants are unable to provide a stool sample) collected throughout the study to assess adherence, biomarkers, and to confirm recurrence of CDI (if necessary).
Summit is developing ridinilazole as a novel antimicrobial for Clostridioides difficile Infection (CDI), formerly known as Clostridium difficile Infection, with the goal of demonstrating an improved Sustained Clinical Response rate in subjects treated with ridinilazole as compared to subjects treated with vancomycin. A phase 2 proof of concept study, with vancomycin as comparator, demonstrated these attributes with a comparable safety profile. A high fecal concentration of ridinilazole and little systemic exposure were noted. The rationale for this phase 3 study is to confirm the improvement in sustained clinical response of CDI over vancomycin and to compare the safety and tolerability of ridinilazole to that of vancomycin. Ridinilazole plasma concentration will be assessed in a subset of patients.
Clostridium difficle infection is the leading cause of hospital acquired infection and infectious diarrhea in hospitalized patients. Eradication treatment for this infection is the challenging tasks for clinicians due to treatment resistance developed from new hypervirulent strains. The recurrence rate of this infection is around 20% and there is high likelihood(60-70%) of another episode after index recurrence. Given constant challenge new treatment options are under study. Aim of the study is to evaluate if use of bismuth subsalicylate (BSS) can decrease the length of stay in patients admitted with Clostridium difficile infection. Secondarily investigators will also see if there is any impact of BSS in decrease the recurrence.
This study will investigate a Clostridium difficile vaccine in healthy adults 65 to 85 years of age, who will each receive 3 doses of vaccine. The study will assess the lot consistency, safety, and tolerability of the vaccine, and also look at the subjects' immune response to the vaccine.
The purpose of this study is to see if stool transplant performed by colonoscopy is effective at treating recurrent Clostridium difficile (C. diff) infection of the colon. During the procedure a stool sample is taken from a healthy donor (usually family member or close friend) and transplanted directly into the colon of the patient with C. diff infection. The goal of this experimental procedure (called fecal microbiota transplantation) is to replenish the good bacteria in the colon that can help prevent C. diff infection from coming back after treatment.
Multi-center, randomized, placebo controlled, partially blinded trial comparing the safety and efficacy of fecal microbiota transplantation versus placebo both delivered by rectal enema in subjects 18 years of age or older with recurrent Clostridium difficile Associated Disease (CDAD). 162 male or female subjects will be enrolled in the study. Enrolled subjects will be randomized at each site to receive either FMT by enema or placebo by enema in a 2:1 ratio. Study duration is 3 years, subject participation duration is approximately 1 year. The primary study objectives are: 1) to evaluate the safety of FMT(s) delivered by enema vs. placebo delivered by enema and 2) to determine efficacy of FMT delivered by enema vs. placebo delivered by enema.
This is an open-label study evaluating the safety and efficacy of CP101 treatment in 1) Subjects in CDI-001 who had a CDI recurrence within 8 weeks of receiving CP101 or placebo; OR 2) adults with recurrent CDI who are eligible for direct study entry into CP101-CDI-E02. Subjects who are experiencing recurrent CDI will undergo screening procedures. Subjects who meet eligibility criteria will be eligible to be enrolled in he study and administered CP101. Approximately 200 subjects will receive CP101. The treatment duration will be 1 day. Subjects will be monitored for recurrence of CDI, safety, and tolerability for 24 weeks following receipt of CP101. The primary efficacy and safety endpoints will be evaluated at 8 weeks post treatment, and all subjects will continue to be followed for an additional 16 weeks for safety and recurrence of CDI.
This study evaluates the efficacy of prophylaxis with oral vancomycin for preventing recurrent Clostridium difficile Infection (CDI) in patients who have experienced at least one CDI episode in the last 180 days and are receiving antibiotics for a non CDI condition. Participants will be randomized to receive either placebo or oral vancomycin in addition to their prescribed antibiotic therapy.
The purpose of this study is to determine the risks and benefits of antibiotic treatment for Clostridium difficile infection (CDI) among patients whose stool samples are nucleic acid amplification test (NAAT) positive and enzyme immunoassay (EIA) negative for C. difficile. Currently, healthcare facilities use a wide variety of tests and strategies for identifying patients with CDI; both EIA and NAAT are widely used. There is no clear gold standard for identifying CDI. At WUSM and BJH, patients are only treated for CDI if they have a positive EIA. However, at many other healthcare facilities, the standard of care is to treat for CDI if the patient is NAAT positive. Some patients who are NAAT-positive may not have true CDI; while this treatment is standard of care at many facilities, the risk and benefits of treating these patients for CDI is unknown. We propose to perform a double blinded, randomized controlled non-inferiority trial of antimicrobial of patients who are EIA negative, NAAT positive to determine the risks and benefits of CDI treatment in this population.
To establish optimal dosing of lyophilized Fecal microbiota transplantation (FMT) product in the treatment of recurrent C. difficile infection
This is a prospective, multicenter, randomized, double-blinded, placebo-controlled Phase 3 study of a microbiota suspension of intestinal microbes. Patients who have had at least one recurrence after a primary episode and have completed at least one round of standard-of-care oral antibiotic therapy or have had at least two episodes of severe Clostridioides difficile infection (CDI) resulting in hospitalization within the last year may be eligible for the study. Subjects who are deemed failures following the blinded treatment per the pre-specified treatment failure definition may elect to receive an unblinded dose of RBX2660.
