Clinical Trial 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.

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.

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

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Assess Efficacy of Oral FMT on Composition and Function of the Gut Microbiota Compared to Placebo.	Assess microbial composition of stool using 16s targeted sequencing and shotgun metagenomics	60 days
Secondary	Comparison of Treatment-related Adverse Events in the Oral FMT Regimens Versus Placebo.	Proportion of participants with treatment-related adverse events as assessed by CTCAE v4.0, including serious adverse events, will be assessed. We will also assess proportion of newly diagnosed infectious diseases, which are considered adverse events of special interest (AESI) after randomization.	60 days
Secondary	Determine the Rate of Clostridium Difficile Infection (CDI) During Oral FMT Regimens Versus Placebo	Collection of CDI infection rates from baseline to end of study and comparison between both oral FMT groups versus placebo.	60 days
Secondary	Evaluate Time to Clostridium Difficile Infection (CDI) and/or Colonization With C. Difficile.	C. difficile colonization will be detected in stool samples submitted at baseline through end of study. If patients' become colonized, time from randomization to colonization is collected. Comparisons are made between the oral FMT groups and placebo.	60 days
