What this trial studies
This observational registry aims to enroll 4,000 patients undergoing fecal microbiota transplantation (FMT) across 75 sites in North America. It will collect detailed information on FMT methodologies, recipient characteristics, and indications for FMT. Patients will be followed for up to 10 years post-procedure, with regular assessments of safety and effectiveness conducted through healthcare provider follow-ups and direct patient communication. The goal is to gather comprehensive data to better understand the short and long-term outcomes of FMT.
Why it matters
Potential benefit: If successful, this registry could provide valuable insights into the safety and effectiveness of fecal microbiota transplantation for patients with Clostridium difficile infection and other gut-related issues.
How similar studies have gone: Other studies on fecal microbiota transplantation have shown promising results, indicating that this approach is gaining traction and is supported by previous findings.
