Intervention model description: This is a phase 2, double-blind, randomized, placebo-controlled trial assessing the effects of either daily (group 1) or one-time (group 2) oral FMT on the composition and function of gut microbiome compared to placebo (group 3) in a population of patients with a history of Clostridium difficile infection (CDI).
Primary purpose: TREATMENT

Brief summary: The primary objective of this study is to compare the gut microbiota and clinical outcomes of oral FMT during antibiotic treatment, immediately following antibiotic treatment, and placebo. The second objective is to assess the safety and feasibility of daily oral Fecal Microbiome Transplant (FMT) as a treatment option.

Detailed description: Clostridium difficile is the most frequent bacterial cause of antibiotic-associated diarrhea. Those with a previous C. difficile infection (CDI) are at high risk of recurrent infection. Recurrent CDI often occurs when the normal gut microbiota are disrupted. Dysbiosis of the gut microbiota predisposes to CDI which, despite treatment can recur in 30% of patients. A novel way to prevent CDI recurrence is by instilling feces from a healthy individual into the intestine of the CDI patient, thereby restoring balance in the gut microbiota. However, it is unknown whether or not fecal microbiota transplantation (FMT) is an efficacious choice for CDI recurrence prevention when used concurrently with antibiotics. We propose a pilot randomized, double-blind placebo controlled trial comparing oral FMT with placebo in patients with a history of CDI, currently undergoing antibiotic treatment. We will collect fecal samples from subjects prior to, during, and after FMT and collect metagenomics and microbiologic data on microbiota composition and function, and CDI recurrence. The trial's primary outcome is gut microbial composition and function. Secondary outcomes are feasibility and safety, and recurrent CDI during the trial period. In this 3 group study, FMT will be administered daily via oral capsules containing frozen fecal microbiota from universal donors in group 1, administered at the end of antibiotic treatment for group 2, and group 3 will receive daily placebo. The results of this study will provide the necessary pilot data to examine whether or not concurrent FMT in antibiotic treated patients who are at high risk for recurrent CDI can maintain a diverse healthy GI microbiota.

Eligibility criteria: Inclusion Criteria:

1. Cognitively intact and willing to provide informed consent
2. Willing and able to comply with all study procedures for the duration of the study
3. Able to take oral medications
4. Age 18 or over
5. Recent CDI episode occurring in the last 180 days with completion of therapy as confirmed by the electronic medical record (EMR)
6. Receiving antibiotics at enrollment for reasons other than CDI and having taken the antibiotics for no longer than 10 days.
7. Women of childbearing potential in a sexual relationship with men must use an acceptable method of contraception (including, but not limited to, barriers with additional spermicidal foam or jelly, intrauterine devices, hormonal contraception started at least 30 days before enrollment into the study, or intercourse with men who underwent a vasectomy) for 4 weeks following completion of the study treatment,
8. Males must agree to avoid impregnation of women during and for 4 weeks following completion of the study treatment.
9. Able to take the test capsule successfully with no signs or symptoms of dysphagia.

Exclusion Criteria:

1. Females who are pregnant, lactating, or planning to become pregnant during the study. Female patients of childbearing potential will take a pregnancy test at the intervention visit and will be excluded if pregnant.
2. Inability (e.g. dysphagia) to or unwilling to swallow capsules
3. Known or suspected toxic megacolon and or known small bowel ileus
4. Bowel obstruction or other gut motility issues occurring in the last two weeks taht are unresolved as noted by the patient or in the EMR
5. Major gastrointestinal surgery (e.g. significant bowel resection) within 3 months before enrollment not including appendectomy or cholecystectomy.
6. History of bariatric or colectomy surgery
7. Concurrent intensive induction chemotherapy, radiation therapy, or biologic treatment for an active malignancy. Patients on maintenance chemotherapy may be enrolled after consultation with the medical monitor.
8. Expected life expectancy less than 6 months.
9. Patients with severe anaphylactic or anaphylactoid food allergy.
10. Solid organ transplant recipients ≤90 days post-transplant or on active treatment for rejection
11. Neutropenia (≤500 neutrophils/mL) or other severe immunosuppression. Anti-tumor necrosis factor (TNF) will be permitted. Patients on monoclonal antibodies to B and T cells, glucocorticoids, antimetabolites (azathioprine, 6-mercaptopurine, methotrexate), calcineurin inhibitors (tacrolimus, cyclosporine), and mycophenolate mofetil may only be enrolled after consultation with the medical monitor.
12. At risk of CMV/EBV associated disease, negative immunoglobulin gamma (IgG) testing for cytomegalovirus (CMV) or Epstein Barr Virus (EBV)
13. Any other gastrointestinal illness including diarrhea
14. On oral vancomycin or metronidazole
15. Having been taking the currently prescribed antibiotic for over 10 days
16. Any condition that would jeopardize the safety or rights of the patient, would make it unlikely for the patient to complete the study, or would confound the results of the study.
