NCT ID NCT07368946
First seen Jan 29, 2026 · Last updated Jun 23, 2026 · Updated 22 times
Summary
This pilot study is testing how different levels of dietary phosphorus affect people with chronic kidney disease (stages 3-4). Participants will follow a controlled meal plan with increasing phosphorus intake over 21 days. The goal is to find new biomarkers and create a better way to measure phosphate overload, which could help guide early treatment.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
dietary phosphorus (as sodium phosphate capsules and controlled meals)
What this could lead to
If successful, this could lead to better ways to measure phosphate overload in kidney disease patients, helping doctors intervene earlier.
What could go wrong
This is a small, early pilot study (60 people) that only looks at biomarkers, not health outcomes. Results may not apply to all patients.
