Fecal microbiota transplantation (FMT) is a treatment that restores the balance of gut bacteria and is the most effective treatment for patients who suffer from recurrent Clostridioides difficile infection (CDI) brought on by antibiotic use. Although highly effective, we do not understand how FMT actually works.
Freeze-dried or lyophilized fecal microbiota transplant (LFMT) has been shown to be effective. Recently, filtered fecal slurry, free of any live bacteria, has also been shown to cure 5 such patients. The advantage of the filtered fecal slurry is that it may be safer to patients as it does not contain any live bacteria. We have conducted a pilot study comparing LFMT to lyophilized sterile fecal filtrate (LSFF) in 9 patients, and found that the success rate of treatment was 80% vs 75% in these 2 groups.
Therefore we need to perform a larger multicenter study to compare LFMT to LSFF to determine the success rate of curing these patients.
|Condition or disease||Intervention/treatment||Phase|
|Clostridia Difficile Colitis Clostridium Difficile Diarrhea||Biological: Lyophilized fecal microbiota transplant Biological: Lyophilized sterile fecal filtrate||Phase 2|
This prospective double blind randomized study will enroll 110 patients with recurrent Clostridium difficile infection (RCDI) in a 1:1 ratio to receive either LFMT or LSFF by capsules.
Patients will receive 15 capsules at week 0 and be assessed at weeks 1, 4, 8 and 24. Blood, stool and urine samples will be collected. If the first treatment fails, patients will be given open label LFMT from the same donor. If treatment fails again, FMT will be offered in the form and route at the treating physician's discretion.
