Brief Summary:
The objective is to examine the effect of Fecal Microbiota Transplantation (FMT) compared with vancomycin for cure of recurrent C. diff infection (CDI) in solid organ transplant (SOT) recipients in a randomized, controlled clinical trial.

Condition or disease Intervention/treatment Phase
Clostridium Difficile Infection Recurrence Drug: FMT oral capsule Drug: Oral Vancomycin Drug: FMT oral placebo Drug: Oral Vancomycin placebo Phase 2

Detailed Description:
Clostridium difficile (C.difficile) is a pathogen of major public health importance, especially in individuals with comorbid conditions such as solid organ transplantation (SOT). The incidence and adverse outcomes of CDI are greatly amplified in the setting of SOT, due to healthcare exposure, antibiotic use and immunosuppression, all of which are ubiquitous in SOT recipients. There are currently no effective treatment options to achieve a sustained cure of recurrent CDI and prevent further recurrence in SOT recipients. A novel approach that has recently gained attention is restoration of the CDI impaired gut microbiome by instillation of stool from a healthy donor into the intestine of a CDI patient. This treatment, called Fecal Microbiota Transplantation (FMT) has been found in non-comparative studies to reduce CDI recurrence dramatically with a reported efficacy of over 95%, however its efficacy in SOT recipients has not been studied and cannot be extrapolated from results in the non-SOT population because SOT recipients are a unique study population due to profound immunosuppression, frequent antibiotic use and frequent opportunities for exposure to CDI all of which markedly, repeatedly and persistently disrupt the gut microbiome. Thus, this critical gap in the field needs to be addressed by a trial of FMT in SOT recipients with CDI.

Primary Outcome Measures :
  1. Compare the rate of recurrence of CDI in solid organ transplant recipients with FMT compared with oral vancomycin [ Time Frame: 2 consecutive days ]
    Recurrence is defined as diarrhea (greater or equal to 3 or more loose stools that take the shape of the collection container in a 24 hr period)

Secondary Outcome Measures :
  1. CDI-related QOL [ Time Frame: At baseline, week 4 and at 29 weeks ]
    Cdiff 32

  2. Compare the change in gut microbiota and evaluate the association between the change in gut microbiota and recurrence of CDI [ Time Frame: up to 30 weeks of study participation ]
    Using multiple metric of microbiota structure and function

  3. Evaluate the short- and medium-term safety of FMT in SOT patients [ Time Frame: Up 30 weeks of study participation ]
    Closely follow safety events

  4. Compare the effects of FMT and oral vancomycin on intestinal colonization by multi-drug-resistant organisms other than C. difficile in SOT patients [ Time Frame: up to 30 weeks of study participation ]
    Analysis of stool samples
