About the trial

What the trial wants to find out

In this phase II trial, the investigators overarching goal is to demonstrate the feasibility and potential benefit of darbepoetin (Darbe) plus slow-release intravenous (IV) iron to decrease transfusions, maintain iron sufficiency and improve the neurodevelopmental outcomes of preterm infants.

Read full original descriptionShow less

Investigators hypothesize that in infants < 32 completed weeks of gestation, combined treatment with Darbe plus Ferumoxytol (FMX) or Darbe plus low molecular weight iron dextran (LMW-ID) will: 1) be safe, 2) decrease or eliminate transfusions, 3) maintain iron sufficiency, 4) result in higher hematocrit and 5) improve neurodevelopment. Investigators further hypothesize that when compared to oral iron supplementation (standard care), IV iron will be better tolerated, with less effect on the gastrointestinal (GI) microbiome

The 5 groups in the trial

  • Group 1. Oral ironExisting treatment, for comparison

    Oral iron is started on day 7 of life if baby is feeding 100 mL/kg/day. Iron supplements of up to 12 mg/kg/day are given based on CBC, retic, ret-hgb, serum ferritin and zinc protoporphyrin to heme ratio (ZnPP/H). Iron supplements are adjusted every 2 weeks following iron studies.

    Treatment: Oral iron supplements

  • Group 2Treatment being tested

    Infants randomized to this arm will receive Darbe 10 mcg/kg q week started on day 3 of life. In addition, beginning on day 7, they will receive LMW-ID: 10 mg/kg x 1, retreat if ferritin \< 76 mcg/L

    Treatment: Darbepoetin Alfa and Low Molecular Weight Iron Dextran

  • Group 3Treatment being tested

    Infants randomized to this arm will receive Darbe 10 mcg/kg q week started on day 3 of life. In addition, beginning on day 7, they will receive LMW-ID: 20 mg/kg x 1, retreat if ferritin \< 76 mcg/L

    Treatment: Darbepoetin Alfa and Low Molecular Weight Iron Dextran

  • Group 4Treatment being tested

    Infants randomized to this arm will receive Darbe 10 mcg/kg q week started on day 3 of life. In addition, beginning on day 7, they will receive FMX: 10 mg/kg x 1, retreat if ferritin \< 76 mcg/L

    Treatment: Darbepoetin Alfa and Ferumoxytol injection

  • Group 5Treatment being tested

    Infants randomized to this arm will receive Darbe 10 mcg/kg q week started on day 3 of life. In addition, beginning on day 7, they will receive FMX: 20 mg/kg x 1, retreat if ferritin \< 76 mcg/L

    Treatment: Darbepoetin Alfa and Ferumoxytol injection
