Who could benefit from this research

Could help

Pregnant individuals diagnosed with iron-deficiency anemia who are in any trimester and are eligible for iron therapy.

Less likely to help

Patients who do not have iron-deficiency anemia or have contraindications to IV iron may not benefit.

What this research studies

If you are pregnant and have iron-deficiency anemia, this trial will compare giving iron through an IV versus by mouth to see which approach keeps anemia from worsening and lowers the chance you’ll need a blood transfusion around delivery. The researchers will enroll multiple medical centers and randomly assign participants to IV or oral iron, tracking anemia status, side effects, and outcomes for both mom and baby. The goal is to identify a delivery method that is effective, safe, and easier for patients to tolerate and adhere to throughout pregnancy.

Why it matters

Potential benefit: If successful, the trial could show that IV iron reduces anemia and related risks for mothers and babies, potentially changing standard care.

How similar studies have gone: Preliminary data suggested that oral iron often fails due to side effects and adherence, making IV iron a promising alternative; this trial seeks to confirm effectiveness at scale.
