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.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

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.
