New iron drug could help anemic kids with kidney problems
NCT ID NCT03619850
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a drug called ferumoxytol, a type of intravenous iron, to treat iron deficiency anemia in children aged 2 to 17 with chronic kidney disease. The trial compares ferumoxytol to another iron drug, iron sucrose, to see which is safer and works better. About 129 children will take part, and the main goal is to see if their hemoglobin levels improve within 5 weeks.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Ferumoxytol (a form of intravenous iron)
- What this could lead to
- If it works, this could offer a safer and more effective way to treat iron deficiency anemia in children with chronic kidney disease.
- What could go wrong
- This is a phase 3 trial, but it's still relatively small (129 participants) and open-label, which can introduce bias. There are also risks like allergic reactions or low blood pressure.
