Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are pregnant women aged 18-45 with singleton gestation and diagnosed with moderate-to-severe iron-deficiency anemia.
✕Probably not a fit
Patients with non-iron-deficiency anemia or those with conditions that affect iron absorption may not benefit from this study.

What this trial studies
This clinical trial is a double-blind, placebo-controlled, multicenter randomized trial involving 746 pregnant women in the U.S. who have moderate-to-severe iron-deficiency anemia. The study aims to compare the effectiveness, safety, and cost-effectiveness of intravenous iron versus oral iron supplementation in reducing severe maternal morbidity and improving offspring neurodevelopment. Participants will be monitored for outcomes such as the need for blood transfusions and the health of their newborns. The trial specifically targets women between 13 to 30 weeks of gestation with low hemoglobin and ferritin levels.
Why it matters
Potential benefit: If successful, this study could provide a more effective treatment option for iron-deficiency anemia in pregnant women, potentially reducing complications for both mothers and their babies.
How similar studies have gone: Previous studies have indicated that intravenous iron can be effective in treating iron-deficiency anemia, but this specific comparison in a pregnant population is novel.
