RecruitingPhase 3Drug trialIntravenous Versus Oral Iron for Treating Iron-Deficiency Anemia in PregnancyDouble blind, placebo controlled, multicenter randomized trial in pregnant women in the U.S. (N=300) to test the central hypothesis that IV iron in pregnant women with IDA (Hb\<11 g/dL and ferritin\<30 ng/mL) at 13 - 30 weeks will be effective, safe and cost-effective in reducing severe maternal morbidity-as measured by maternal anemia at delivery-and will also improve offspring neurodevelopment.
