Evaluating phosphate level targets in patients with end-stage kidney disease
Official title: An Investigator-initiated, International, Multi-centre, Prospective, Randomized, Open-label, Parallel-group, Superiority, and Pragmatic Large Simple Trial (LST) to Determine Whether the Currently Recommended Strategy of Intensive Reduction of Serum Phosphate Concentration Towards the Normal Level Results in Significant Patient-centred Benefits in End-stage Kidney Disease (ESKD) Patients Receiving Dialysis.
Run by The University of Queensland · NCT03573089 · Data updated 2026-11-12
This study tests if lowering blood phosphate levels more strictly helps adults with end-stage kidney disease feel better and reduces their risk of heart problems.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 45 and older, or those aged 18 and older with diabetes, who have been on dialysis for at least three months and are currently prescribed phosphate-lowering medications.
✕Probably not a fit
Patients scheduled for elective kidney transplantation or those with major comorbidities that may lead to death within six months may not benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This trial investigates the impact of lowering blood phosphate levels in patients with end-stage kidney disease (ESKD) on critical health outcomes. It compares a liberal phosphate target of 2.0 to 2.5 mmol/L with an intensive target of ≤1.50 mmol/L to determine which approach better reduces the risk of cardiovascular events and improves overall patient health. The study involves 3600 adult patients receiving dialysis and utilizes phosphate binders as part of the treatment regimen. The primary focus is on patient-centered outcomes, including mortality and quality of life.
Why it matters
Potential benefit: If successful, this study could lead to improved survival rates and quality of life for patients with end-stage kidney disease.
How similar studies have gone: While there is a lack of direct trial data on this specific approach, the study builds on existing guidelines and preliminary evidence suggesting that managing phosphate levels is crucial for ESKD patients.
