New treatment for high oxalate levels and kidney stones

Official title: SLC26A3 (DRA) Inhibitors for Treatment of Hyperoxaluria and Nephrolithiasis

Funded at University of California, San Francisco · NIH-10877183 · Data updated 2026-11-12

This study is looking at a new way to help people with hyperoxaluria, a condition that can cause kidney stones, by blocking a protein in the colon that makes the body absorb too much oxalate, so that more oxalate can be removed through stool instead of ending up in the urine.

Who could benefit from this research

Could help

Ideal candidates for this research include individuals with hyperoxaluria, particularly those with a history of kidney stones or chronic kidney disease.

Less likely to help

Patients who do not have elevated oxalate levels or related kidney conditions may not benefit from this research.

What this research studies

This research investigates a novel approach to treat hyperoxaluria, a condition characterized by high levels of oxalate in the urine that can lead to kidney stones and chronic kidney disease. The study focuses on inhibiting a specific protein, SLC26A3, in the colon that facilitates the absorption of oxalate, thereby promoting its excretion through stool. By blocking this protein, the researchers aim to reduce the amount of oxalate that enters the urine, potentially alleviating the risk of kidney stone formation and protecting kidney function. The research utilizes both animal models and human data to explore the effectiveness of these inhibitors.

Why it matters

Potential benefit: If successful, this research could provide a new treatment option for patients suffering from hyperoxaluria and related kidney issues.

How similar studies have gone: Previous research has shown promising results with similar approaches targeting oxalate absorption, suggesting potential for success in this novel treatment strategy.
