Access Criteria

Study Characteristics


To assess the efficacy of fecal microbiota transplantation (FMT) for the prevention of subsequent recurrent Clostridium difficile infection (CDI), when administered after successful treatment of recurrent CDI with standard antimicrobial therapy.

Era of Service



Veterans living anywhere in the US who are enrolled at a VA facility, aged 18 and older, who:

  • Have had one or more episodes of recurrent difficile infection
  • Have had resolution or improvement of symptoms from the most recent CDI episode
  • Enroll within 2 to 14 days after completion of antimicrobial therapy or 30 days after the onset of CDI (whichever is later)
  • And are able to provide informed consent

Study Design

  • FMT: Half the participants will receive Fecal Microbiota Transplant (FMT) via oral capsule
  • Placebo: Half the participants will receive a placebo (sugar pill). The assignment is random, and the participant will not know what they received
  • All participants: All participants will be followed via phone at days 2, 14, 28, 42, and 56 after capsule administration, and once a month thereafter until month 6

Time Period

November 2018 – November 2023




390 participants

Response Rate

As of 2/28/21, a total of 1,926 patients were screened, 102 were eligible, and 102 underwent randomization.

Recruitment Method

The Minneapolis VA Medical Center centrally recruited patients nationwide who meet the eligibility criteria. Those providing written informed consent were enrolled in the study.  Due to the pandemic, recruitment has been conducted virtually using VA Video Connect (VVC) since September 2020. Priorly the study recruitment was in person.


Participants will receive up to $250 total compensation ($100 at enrollment, $50 at approximately 8 weeks after enrollment, and $100 at approximately 6 months after enrollment).  Compensation will be made either via debit card or electronic funds transfer.

Data Collected

Data collection is still ongoing. 

Types of data being collected are:

  • screening, randomization
  • medical history, baseline medications, quality of life, recurrent evaluations post intervention, and Adverse Events (AE)/Serious Adverse Events (SAEs)

Data Collection Methods

  • Study Coordinators will enroll the patients at their home or place of residence or via VVC.
  • All follow up is via telephone
