Promising drug may protect kidneys in kids with rare oxalate disorder

NCT ID NCT05001269

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tested a monthly injection called nedosiran in 27 children from birth to 11 years old with primary hyperoxaluria, a rare condition that causes harmful oxalate buildup and kidney damage. The goal was to see if the drug safely lowers oxalate levels in the urine. Early results suggest it may help control the disease, but more research is needed to confirm long-term benefits.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
nedosiran (a monthly injection that lowers oxalate production)
What this could lead to
If successful, this could offer a new treatment option for young children with primary hyperoxaluria, potentially reducing kidney damage and delaying or avoiding the need for dialysis or transplant.
What could go wrong
This is a small, early-phase study with only 27 children, so results may not apply to all patients. The drug may cause side effects or fail to lower oxalate enough to prevent long-term kidney problems.
