First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether freeze-dried fecal bacteria, given as oral capsules, can improve symptoms in 40 adults with active rheumatoid arthritis that hasn't responded to standard drugs. Participants will receive either the fecal transplant or a placebo for 24 weeks. The main goal is to see if more people in the treatment group achieve at least a 20% or 50% improvement in arthritis symptoms by week 16.
