Outcomes and Data Collection for Fecal Microbiota Transplantation for the Treatment of Recurrent Clostridium Difficile
What this study is about
The purpose of this study is to see if stool transplant performed by colonoscopy is effective at treating recurrent Clostridium difficile (C. diff) infection of the colon. During the procedure a stool sample is taken from a healthy donor (usually family member or close friend) and transplanted directly into the colon of the patient with C. diff infection.
View original scientific description
The purpose of this study is to see if stool transplant performed by colonoscopy is effective at treating recurrent Clostridium difficile (C. diff) infection of the colon. During the procedure a stool sample is taken from a healthy donor (usually family member or close friend) and transplanted directly into the colon of the patient with C. diff infection. The goal of this experimental procedure (called fecal microbiota transplantation) is to replenish the good bacteria in the colon that can help prevent C. diff infection from coming back after treatment.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Two or more recurrences of C. difficile infection (CDI) with recurrence defined as a positive test result, e.g. Polymerase Chain Reaction (PCR) test and with appropriate symptoms within 2-8 weeks of last positive result, provided that symptoms from earlier episode resolved with or without therapy.
- Failed standard therapy with oral metronidazole and/or oral vancomycin
- One or more episodes of severe CDI resulting in hospitalization and not responding to standard antibiotic therapy. Hospitalization for CDI occurs in the setting of severe diarrhea, abdominal pain and signs of systemic toxicity
Exclusion criteria
- Age \<16 years old
- patients with acute severe colonic dilation at risk for colonic perforation
Where
- Worcester, Massachusetts
Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
