Clinical Trial Summary

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.

Description:

Population: Patients >= 18 years hospitalized at Boston Medical Center (BMC) with a first documented episode of CDI.

Intervention: 30 FMT capsules administered orally under direct observation within 7 days of completion of 10-14 day treatment of oral vancomycin for CDI.

Objectives:

1. To characterize the microbial diversity in stool samples from subjects with a primary episode of CDI before and after oral vancomycin and determine the impact of FMT after completion of oral vancomycin course.

2. To characterize the feasibility and tolerability of FMT after completion of a course of oral vancomycin therapy for primary CDI, and to describe 30-day hospital readmission and gastrointestinal symptomatology and/or CDI recurrence during 60-day follow-up.

Design/Methodology:

15 subjects will be enrolled who are hospitalized at BMC for a primary episode of CDI. A discard aliquot from baseline stool samples obtained clinically for diagnosis will be frozen. Subjects will receive the standard of care treatment (oral vancomycin for 10-14 days) and within 7 days following completion will receive oral FMT during a 2 hour visit in the Infectious Disease (ID) Clinical Trials Unit. An additional 5 subjects will be enrolled as controls. Stool samples will be collected at time of CDI diagnosis and again 3 weeks after FMT for intervention group and 4 weeks after completion of oral vancomycin treatment for control subjects. The post-treatment samples will be obtained by the patient using special stool sample collection kits known as RNAlater kits (ribonucleic acid stabilization). These contain a liquid nontoxic tissue storage reagent known as RNAlater and helps preserve the stool sample. The subjects will mail this stool sample to the BMC Clinical Trials Unit (CTU) where it will aliquoted, centrifuged and frozen.

Samples will be processed at a collaborating lab at Tufts to characterize the fecal microbiome pre- and post oral FMT.

Study personnel will contact participants via telephone 60 days after FMT dosing to administer a follow-up survey (including questions on residual symptoms. CDI recurrence, re-hospitalization, adverse events and FMT acceptability).

Total Study Duration: Anticipated time: 12 months

Subject Participation Duration: The researchers anticipate a period of 1-2 hours while an inpatient for the screening and consent process, 2 hours for the CTU visit for FMT and 20-30 minutes responding to a follow up telephone survey. Total time in the study from enrollment to completion of follow-up will be approximately 3 months and will include 10-14 days of CDI treatment with oral vancomycin (per standard of care treatment), the FMT administration and a 60 day follow up.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Stool Microbiome With and Without FMT Administration	The stool microbiome in participants who receive additional FMT at end of Clostridium difficile infection (CDI) treatment with oral vancomycin will be compared to the stool microbiome in participants with standard treatment or oral vancomycin alone	11 months
Secondary	Feasibility of Administering FMT After Completion of a Course of Oral Vancomycin Therapy	The number and proportion of FMT pills participants ingest after completion of a course of oral vancomycin therapy will be documented.	12 months
