Study summary

Clostridium difficile associated diarrhea (CDAD) is a significant cause of morbidity and mortality, caused by loss of healthy gut flora. Conventional treatment uses antibiotics to kill Clostridium difficile. A novel treatment uses replacement of gut flora by fecal microbiota transplant (FMT). Randomized trials have established safety and efficacy of FMT in recurrent CDAD, but no trial has used FMT for primary CDAD. This study will randomize patients to oral encapsulated FMT or oral Vancomycin.

Read the detailed description

Patients with primary CDAD will be approached for consent and randomized equally to two arms: oral FMT with oral Vancomycin placebo, or oral FMT placebo with oral Vancomycin. FMT will be prepared from anonymous donors screened according to Health Canada guidelines and stored frozen.

What researchers measure

Primary outcomes

  1. Efficacy: Cure of diarrhea without recurrence in intention to treat population

    Cure is defined as less than 3 bowel motions per day for 2 consecutive days during the 10 day treatment period. Recurrence is defined as 3 or more bowel motions within one day during the follow-up period.

    Time frame: 56 days

  2. Adverse Events

    Number of participants with treatment-related adverse events as defined by the Medical Dictionary for Regulatory Activities.

    Time frame: 56 days

Secondary outcomes

  1. Efficacy: Cure of diarrhea without recurrence in a per protocol population

    Cure is defined as less than 3 bowel motions per day for 2 consecutive days during the 10 day treatment period. Recurrence is defined as 3 or more bowel motions within one day during the follow-up period.

    Time frame: 56 days

  2. Efficacy: cure of diarrhea in intention to treat and per protocol populations

    Cure is defined as less than 3 bowel motions per day for 2 consecutive days during the 10 day treatment period.

    Time frame: 10 days

  3. Efficacy: time to cure of diarrhea

    Cure is defined as less than 3 bowel motions per day for 2 consecutive days during the 10 day treatment period.

    Time frame: 56 days

  4. Efficacy: Health status questionnaire

    Time frame: 56 days
