ButOx Human Trial: An Open Label Prospective Cohort Study to Investigate the Effect of Tributyrin (Butyrate Precursor Molecule) Supplementation on Markers of Calcium Oxalate Nephrolithiasis (NCT07004257)

🟡 Not Yet Recruiting Observational / Diagnostic 📋 Clinical Research Protocol Sponsor: University of British Columbia

🩺 Plain-English Summary (8th-Grade Level)

Kidney stone disease (KSD) is a condition where there are crystal deposits in the kidney. The gut microbiome is a community of gut bacteria which can produce substances such as short chain fatty acids (SCFAs). Individuals with KSD have a different gut microbiome composition and lower amounts of these SCFAs compared to healthy individuals. Tributyrin is a supplement which can increase levels of SCFAs. Our data from animal studies indicate that tributyrin supplementation may be able to reduce kidney stone formation. This pilot clinical trial will test if tributyrin supplementation helps in prevention or treatment of those with KSD.
