Clostridium Difficile
Conditions
Brief summary
This is a single center, randomized, parallel assignment, double-blinded, efficacy and safety study to be conducted in subjects with recurrent C. difficile Infection (RCDI). Approximately 200 subjects will be enrolled in the study and randomized at 1:1 ratio to receive lyophilized intestinal bacteria obtained from either single or three donors (group 1 receiving healthy microbiota collected from single donor 90g stool for 2 consecutive days; group 2 receiving healthy microbiota collected from three donors 90g stool for 2 consecutive days). All subjects will be followed for approximately 180 days following FMT treatment for safety.
Detailed description
The endpoints of the study are to evaluate the efficacy and safety of lyophilized product by capsules obtained either from single or three donors and the prevention of subsequent bouts of CDI in 60 days post FMT.

Masking description
An independent statistician will develop a randomization list using SAS. Randomization in permuted blocks will be used to achieve balance across treatment groups. The randomization scheme consists of a sequence of blocks such that each block contains a pre-specified number of treatment assignments in random order. The purpose of this is to balance the randomization scheme at the completion of each block. The target sample size is 200 evaluable subjects or as many as can be done up to that number.
Intervention model description
This is a double-blinded study for the groups randomized to receive FMT products either from single or three healthy donors

Subject must have an attending physician who will provide non-transplant care (Either PI of this study or referring physician). 7. Medical history of ≥ 3 bouts of CDI in outpatient or ≥ 2 bouts of CDI in inpatient with either group having ≥ 2 positive fecal tests for C. difficile toxin and at least one bout of CDI within 6 months of enrollment. 8. Received at least two courses of standard-of-care antibiotic therapy for CDI.
Exclusion criteria
1. Unable to take capsules orally. 2. Requiring systemic non-C. difficile antibiotic therapy within 14 days prior to FMT. 3. Unwilling to stop taking non-dietary probiotics 24-96 hours prior to FMT. 4. Unable to stop taking bile acid sequestrants (e.g. cholestyramine) 24-96 hours prior to FMT. 5. Unable to stop use of drugs with CDI activity: oral vancomycin, oral or IV metronidazole, fidaxomicin, rifaximin or nitazoxanide 24-96 hours prior to FMT and after FMT. 6. Receipt of CDI monoclonal antibodies as treatment for the most recent bout of CDI. 7. Life expectancy of \< 6 months. 8. In the opinion of investigator, subject for any reason, should be excluded from the study.
