Using Darbe and IV iron to reduce transfusions in preterm infants

Official title: Trial of Darbepoetin Plus Slow-release Intravenous Iron to Decrease Transfusions and Improve Iron Status and Neurodevelopment in Preterm Infants

Run by University of Washington · NCT05340465 · Data updated 2026-11-12

This study is testing if giving preterm infants a combination of a special medication and intravenous iron can help reduce the need for blood transfusions and support their growth and development better than regular oral iron.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are NICU patients born between 24 and 31 weeks of gestation who require treatment for iron deficiency.

Probably not a fit

Patients with significant fetal or infant anomalies, high iron stores, or severe infections at enrollment may not benefit from this study.

What this trial studies

This phase II trial aims to evaluate the safety and efficacy of darbepoetin (Darbe) combined with intravenous iron formulations (Ferumoxytol or low molecular weight iron dextran) in preterm infants born before 32 weeks of gestation. The study will compare these treatments to standard oral iron supplementation to determine their impact on reducing transfusions, maintaining iron sufficiency, and improving neurodevelopmental outcomes. Participants will be monitored for adverse reactions and long-term effects on the stool microbiome. The trial will include assessments of hematocrit levels and neurodevelopmental progress up to two years of age.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the need for blood transfusions in preterm infants while ensuring adequate iron levels and promoting better neurodevelopment.

How similar studies have gone: Other studies have shown promise in using intravenous iron for similar populations, but this specific combination approach is relatively novel.
