Early Antenatal Support for Iron Deficiency Anemia (EASI-A)
November 25, 2025 updated by: Thomas Jefferson University
Early Antenatal Support for Iron Deficiency Anemia: A Randomized Controlled Trial of Early Initiation of Intravenous Versus Oral Iron Therapy for Treatment of Iron Deficiency Anemia in Pregnancy
This is a randomized, controlled multi-site trial of iron therapy in pregnancy.
The purpose of this research is to see if second trimester initiation of intravenous (IV) iron therapy is better than oral iron therapy for treatment of anemia in pregnancy by improving blood count, quality of life and reducing side effects.

Detailed Description
Pregnant singletons diagnosed with iron deficiency anemia will be enrolled between 14-24 weeks and will be randomized 1:1 to either a course of ferumoxytol (510mg x 2 doses 3-8 days apart) or oral iron (325mg) twice daily.
