Fecal Microbial Transplantation for Rheumatoid Arthritis Trial

This clinical trial will investigate the effects of capsules containing stool from healthy donors, called fecal microbial transplant (FMT), in rheumatoid arthritis patients.

This is a randomized double-blind placebo-controlled proof-of-concept trial. A total of 30 RA patients will be asked to join the study. They will be randomized to receive capsular FMT + standard of care or placebo + standard of care. There will be four study visits in total: Baseline, FMT administration, 6- and 12-week follow-up visits. Follow-up visits will consist of assessment by a rheumatologist, completion of surveys, and collection of biologic samples. Samples for the study are stool, urine and blood. Blood and fecal samples will be collected at baseline, 6 weeks and 12 weeks. Urine samples will be collected at baseline and 6 weeks.
