Multispecies Synbiotic in hemodialysis patients with CKD
Official title: Alterations of Gut Derived Uremic Toxins and Microbiome Metabolites by Multispecies Synbiotic Supplementation in Hemodialysis Patients
Run by Tungs' Taichung Metroharbour Hospital · NCT07443280 · Data updated 2026-11-12
This pilot study tests whether a multispecies synbiotic can lower gut-derived toxins and reduce inflammation in adults on maintenance hemodialysis.

Is this trial a fit for you?
✓Likely a good fit
Adults on maintenance hemodialysis for at least 3 months who have not used probiotic supplements recently and do not have exclusionary conditions.
✕Probably not a fit
Patients with recent antibiotic use, active infections, major intestinal surgery, severe liver disease, active cancer, or other exclusion criteria may not benefit or could be at risk.

What this trial studies
This is a single-arm, open-label pilot study enrolling adults on maintenance hemodialysis to see if 12 weeks of a multispecies synbiotic (Renobiome) can reduce gut-derived uremic toxins and inflammatory markers. Participants will take one capsule twice daily and undergo baseline and 12-week assessments of serum and urinary toxins, plus gut microbial metabolites. Safety monitoring occurs at 4 weeks, and outcomes include changes in indoxyl sulfate, p-cresyl sulfate, and related inflammatory markers. The study plans to enroll about 30 participants to detect a medium effect size with adequate power. Results will inform whether multispecies synbiotics merit further testing in larger trials.
Why it matters
Potential benefit: If successful, patients may experience lower levels of gut-derived toxins and reduced systemic inflammation.
How similar studies have gone: Prior probiotic studies show mixed results; this pilot addresses multispecies synbiotics specifically in a hemodialysis population with GDUTs.
