A Trial of CP101 for the Prevention of Recurrent CDI (PRISM4)
Description

This is a Randomized, Double-Blind, Placebo-Controlled, Phase 3 Trial of the Efficacy, Safety, and Tolerability of a Single Oral Administration of CP101 for the Prevention of Recurrent Clostridioides difficile Infection (PRISM4). This Phase 3 trial will be conducted in 2 parts: a randomized, double-blind, placebo-controlled trial arm and an optional open-label treatment arm. After completing standard-of-care (SOC) CDI antibiotics for their most recent CDI recurrence, patients who meet all eligibility requirements will be randomized in a 2:1 ratio to receive either CP101 or placebo. Patients will be evaluated for CDI recurrence and safety follow-up through Week 8, the primary endpoint, as well as through Week 24. Patients who qualify may enroll into the optional open label arm if they experience CDI recurrence through week 8.

Prospective Trial of Oral Vancomycin Therapy vs. Placebo for Prevention of CDI
Description

The purpose of this research study is to determine in patients receiving intravenous (IV) antibiotic(s), if giving oral vancomycin therapy will prevent C. difficile-associated infection (commonly called CDI). Oral vancomycin is an antibiotic that is commonly used to treat CDI. The investigators want to study if using this drug can prevent the development of CDI while you are in the hospital receiving IV antibiotics. The key risk factors for developing CDI are age and IV antibiotic therapy. CDI is an infection in your colon caused by an organism called Clostridium difficile (or C. diff for short) that causes diarrhea. Up to 12% of hospital-acquired infections have been reported to be CDI. It can lead to longer hospital stays and more costs associated with the hospital stay.

COMPLETED
A Comparison of Fidaxomicin and Vancomycin in Patients With CDI Receiving Antibiotics for Concurrent Infections
Description

Administration of concomitant antibiotics (CA) is a known risk factor for treatment failure in the treatment of CDI, as well as for recurrence of CDI. Recent data suggested that among patients receiving CA, fidaxomicin is superior to vancomycin. While these data are encouraging, many clinicians remain unclear on how to apply these data to patient care. Additionally, patients were excluded from the trials presented to the FDA if it was expected that they would require ≥ 7 days of CA. Therefore, the clinical question still remains of how to apply these data to the real world patient who requires a long course of CA and develops CDI while on therapy. We therefore propose an open label, comparative and prospective study of fidaxomicin 200 mg twice daily vs oral vancomycin 125 mg four times daily for the treatment of CDI among patients who are receiving a long course of CA. We hypothesize that fidaxomicin will be superior to vancomycin with respect to clinical cure for patients with CDI.

FMT Versus Antimicrobials for Initial Treatment of Recurrent CDI
Description

The purpose of the study is to determine the safety and efficacy of Fecal Microbiota Transplant (FMT) for the treatment of the recurrence of Clostridium difficile infection (CDI) as compared to standard antibiotic therapy. Patients who have tested positive for CDI within 90 days of an admission for relapse of CDI will be approached to participate in this open-label, randomized controlled trial. Patients will either be randomized to the intervention group (receive FMT via retention enema) or the control group (receive antimicrobials targeting CDI).

Fecal Microbiota Transplant for Primary CDI
Description

Clostridium difficile infection (CDI) is one of the most urgent health threats in the U.S. associated with antibiotic use. After an initial episode, disease recurrence is high and relapses can occur in 20-30% of people treated with oral vancomycin. An antibiotic course can affect the gut microbiome for years, and patients with CDI have additional dysbiosis of their gut flora. Oral vancomycin perturbs the gut microbiome further. Restoration of the microbiome with Fecal Microbiota Transplant (FMT) has been proven a highly efficacious and cost-effective treatment for recurrent CDI. FMT has had very limited study for a primary episode of CDI to date because an endoscopic procedure was the recommended route of delivery. However, FMT is now available via frozen oral capsules and has been shown to be non-inferior to FMT via colonoscopy in randomized controlled trials. The investigators hypothesize that outcomes after a first episode of CDI can be improved if the microbiome is restored with oral FMT. It is further hypothesized that this will compensate for any additional microbiome perturbation caused by administration of oral vancomycin and decrease the likelihood of recurrence. Because the hypothesis is based on restoration of the microbiome, the investigators propose this proof-of-concept pilot study to examine whether FMT administered after oral vancomycin therapy for primary CDI restores microbiome diversity compared to patients who do not receive FMT. Because of the potential health benefits, this approach deserves further study. The results from this pilot study on the microbiome diversity as well as the surveys to be conducted about GI symptomatology (e.g., diarrhea, abdominal pain, bloating), CDI recurrence and healthcare utilization, would provide preliminary data to support a randomized controlled, multicenter clinical trial.

Oligosaccharide for Cdiff(+) Heme-onc Patients
Description

Clostridium difficile causes \~453,000 infections and \~29,300 deaths per year in the US, making it the most common hospital acquired infection in the country. C. difficile is an anaerobic bacterium that has the capacity to inhabit the colon of humans and other mammals. Initially thought to be a commensal, it was later found to be associated with antibiotic induced enterocolitis. Since then, it has gradually become one of the most important healthcare associated pathogens. C. difficile infection (CDI) causes colitis, which is inflammation of the colonic mucosa with a spectrum of severity from mild to more protracted diarrhea, abdominal pain, fever, toxic megacolon, sepsis, and in some instances death. Mortality occurs despite the existence of three antibiotic options. CDI is also associated with higher hospital readmission rates, and associated healthcare costs in the US are estimated at 4.8 billion dollars annually. Due to the significance of C. difficile in healthcare, hospital level C. difficile rates are publically reported and closely scrutinized by the Centers for Medicare and Medicaid. Standard infection control bundles are proving to be insufficient for controlling the national C. difficile problem. Better understanding of the biological steps preceding clinical infection and reversal of the underlying gut dysbiosis will allow us to curtail our C. difficile epidemic. The present study aims to manipulate the gut microbiota to halt the biological progression of C. difficile. CDI is a serious problem in hematology-oncology patients. The incidence of CDI in the hematology-oncology population is much higher than in other populations and hematology-oncology inpatient units frequently have the highest incidence of CDI cases within an institution. Additionally, hematology-oncology patients have high rates of C. difficile colonization upon hospitalization and more than 50% of patients detected with C. difficile colonization before bone marrow transplantation end up diagnosed with hospital associated CDI. This finding is not trivial as CDI treatment with oral vancomycin causes major and prolonged perturbations of their intestinal microbiota, which has been associated with higher mortality. In addition to the usual complications of CDI, a higher incidence of graft-versus-host-disease has been described in patients with CDI.

PROCLAIM -- Misoprostol in the Prevention of Recurrent CDI Prevent Recurrence of Clostridium Difficile Infection With Misoprostol
Description

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).

EGESTA - Emergent GI Therapy for Severe, Complicated CDI Using Fecal Microbiota Transplant
Description

The objectives/specific aims of this study are three-fold. First, the study seeks to evaluate the safety of fecal microbiota transplant (FMT) in patients with severe, complicated C. difficile infection (scCDI). Second, the study seeks to evaluate whether fecal microbiota transplant (FMT) can improve scCDI, with "improve" defined as either decreasing the severity of CDI, or by resolving the infection altogether. Third, the study seeks to further study the mechanism by which FMT improves the course of scCDI by performing 16S rRNA and ITS sequencing on pre-FMT and serial post-FMT stool samples in order to measure changes to bacterial and fungal microbiota as a consequence of CDI and FMT therapy. FMT material (hereafter referred to as FMTm) would be obtained from OpenBiome. FMTm is prepared from prescreened healthy donors. The hypothesis of the study is that FMT is a preferred salvage therapy for scCDI as compared to (1) ongoing, failing medical therapy with conventional antibiotics and (2) surgery.

RECRUITING
Immune Response to C.Difficile Infection
Description

The protocol aims to address the basic mechanisms of Clostridium difficile pathogenesis by identifying how a Th 17 response impacts severity of C. difficile infection and how Type II immunity protects the gut from Clostridium difficile toxin-induced damage. This could lead to new and effective approaches to the treatment or prevention of Clostridium difficile colitis that act downstream of fecal microbiota transplants (FMT) or next generation probiotics. Successful fecal microbial transplantation will restore protective immunity to recurrent C.difficile infection.

Description

A Phase 2b Parallel-Group, Double-Blind, Placebo-Controlled, Multicenter Study of SYN-004 Compared to Placebo for the Prevention of Clostridium difficile Infection (CDI) in Hospitalized Patients receiving IV ceftriaxone with a Diagnosis of a Lower Respiratory Tract Infection (LRTI).

COMPLETED
Early FMT for C.Difficile
Description

Clostridium difficile infection (CDI) has increased worldwide in both frequency and severity. It is the leading cause of hospital acquired infection in developed countries and has been associated with at least 14,000 deaths per year in the United States. With 3 million cases/ year, the annual cost for treating the infection is exceeding 3 billion dollars. It can also have a profound negative impact on quality of life. The investigators believe that patients who are at high risk of relapse after a first CDI episode would benefit from early fecal microbial transplant (FMT). The proposed study will produce preliminary data regarding safety and efficacy and potential for cost effectiveness for the use of early fecal transplant in those patients with their first episode of non-refractory CDI who are predicted to have a high rate of recurrence based on previously published risk factors. The investigators will be better prepared to test the efficacy of this approach in a future multicenter clinical trial in a randomized controlled fashion. The purpose of this study is to compare the effectiveness and safety of early fecal transplant using donor stool from a healthy person in a group of patients who are diagnosed with their first episode of Clostridium difficile infection and are predicted to have a high chance of the infection returning against a similar group of patients who receive current standard of care for treatment of C.difficile. The investigators hypothesize: * that clinical remission rates at 12 weeks as noted by absence of clinical symptoms and/or negative C.difficile stool polymerase chain reaction (PCR) will be greater in the experimental arm compared to the control arm * that patients in the experimental group will have a low microbial diversity prior to FMT but will exhibit a high microbial diversity after the FMT that resembles the respective donor * that the microbial diversity will be diminished in both groups at the time of enrollment, but the experimental group will exhibit a higher microbial diversity compared to the control population at 12 weeks * that patients in both groups will exhibit poor quality of life at the time of enrollment, however, the experimental group will demonstrate higher quality of life compared to the control group at follow up after completion of treatment * that costs incurred by the experimental group will be less than the control group
