Can a new iron strategy help kidney dialysis patients fight anemia?
NCT ID NCT06884280
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at different ways to give iron to people with kidney failure who are on peritoneal dialysis. Participants will get either high-dose or low-dose intravenous iron, or oral iron tablets. The main goal is to see if a larger trial is possible by checking how many people join, stay, and complete the study over 12 months.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Iron (intravenous iron isomaltoside 1000 or oral ferrous sulfate)
- What this could lead to
- If successful, this could help design a larger study to find the best way to treat anemia in people on peritoneal dialysis, potentially improving energy and quality of life.
- What could go wrong
- This is a small feasibility trial with only 30 participants, so results may not apply to everyone. It is testing whether a bigger study is possible, not yet proving which iron treatment works best.
