Fecal Microbial Transplantation for Rheumatoid Arthritis
(FeMiTRA Trial)
Trial Summary
What is the purpose of this trial?
This clinical trial will investigate the effects of capsules containing stool from healthy donors, called fecal microbial transplant (FMT), in rheumatoid arthritis patients.
Will I have to stop taking my current medications?
The trial does not specify if you need to stop taking your current medications, but it requires that your rheumatoid arthritis therapy has been stable for more than 6 months. If you are on high-dose steroids, biologic therapies, or certain other medications, you may not be eligible to participate.
What data supports the effectiveness of this treatment for rheumatoid arthritis?
Is fecal microbiota transplantation (FMT) generally safe for humans?
FMT is generally considered safe, especially with thorough donor screening and testing. Most short-term risks are related to the delivery method, like colonoscopy, while long-term risks are less understood but have not shown harm in follow-ups. Rarely, it has been linked to serious outcomes, such as the transmission of antibiotic-resistant bacteria.12678
How does fecal microbial transplantation differ from other treatments for rheumatoid arthritis?
Fecal microbial transplantation (FMT) is unique because it involves transferring stool from a healthy donor to a patient to restore gut bacteria balance, which is different from traditional rheumatoid arthritis treatments that typically involve drugs or biologics targeting the immune system. This approach is novel as it focuses on altering the gut microbiome, which may influence inflammation and immune responses in the body.910111213
Eligibility Criteria
This trial is for adults over 18 with rheumatoid arthritis, who have specific RA antibodies and are in remission or have low disease activity. They must be on stable RA therapy for more than 6 months and agree to the study's terms. A healthy donor with a normal BMI will provide stool samples.Inclusion Criteria
