Comparison of Oral Ferrous Sulfate to Intravenous Ferumoxytol in Antepartum Iron Deficiency Anemia

Stanford University·interventional·Posted Feb 5, 2020·Updated Jun 30, 2026

In Brief

A Phase 3 clinical trial evaluating Ferumoxytol Injection [Feraheme] and Ferrous Sulfate for Pregnancy Related and Anemia, Iron Deficiency. Completed, enrolled 83 participants across 1 site.

Detailed Summary

Evaluate the extent to which treatment of iron deficiency anemia beyond 24-34 weeks' gestation of pregnancy with intravenous iron increases hemoglobin compared to oral iron. The investigators will test the hypothesis that pregnant women who are anemic in the second and third trimester are more likely to significantly increase their hemoglobin with intravenous iron as opposed to the usual standard of care, oral iron.

Arms & Interventions

Intravenous ironexperimental

Participants will receive 510mg intravenous iron ferumoxytol, with a maximum of 2 doses based on the baseline hemoglobin level. The ferumoxytol is administered as an infusion for approximately 15 - 30 minutes.

Drug: Ferumoxytol Injection [Feraheme]
Oral ironactive_comparator

Participants will be prescribed 1-2 ferrous sulfate 325mg tablets by mouth (based on severity of anemia) until delivery. For standardization, the dosage is as follows based on severity: one ferrous sulfate tablet for women with baseline hemoglobin 9-11, and two ferrous sulfate tablets for hemoglobin \< 9.

Drug: Ferrous Sulfate
