Can blood transfusions protect pregnant women with sickle cell disease?
NCT ID NCT06979492
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether giving regular blood transfusions during pregnancy can reduce sickle cell complications and pregnancy-related problems in women with sickle cell disease. About 50 pregnant women will be randomly assigned to receive transfusions or standard care. The goal is to see if transfusions lower hospital visits and improve outcomes for both mother and baby.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- red blood cell transfusion
- What this could lead to
- If it works, this could establish a standard practice to prevent serious complications in pregnant women with sickle cell disease.
- What could go wrong
- This is a small Phase 4 trial with only 50 participants, so results may not apply to all. Transfusions carry risks like allergic reactions or iron overload.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Female * Diagnosis of SCD of any genotype (i.e., HbSS, HbSC, HbSβ thalassemia) * 18 Years and older * Currently pregnant at 6 weeks through 20 weeks of gestation. * Ability to understand the purposes and risks of the study and willingly give informed consent. * For participants with private health insurance, insurance pre-approval for blood transfusions Exclusion Criteria: * Currently on chronic transfusion therapy before pregnancy * Prior history of DHTR with hyperhemolysis * Red cell antibody history, which would prevent the provision of adequate red cell units to support chronic transfusions. * Unable or unwilling to receive blood transfusion for social, religious, or clinical reasons * Known current triplet pregnancy * Current diagnosis of major medical or psychiatric comorbidity, which in the randomizing clinician's opinion renders them unable to enter a clinical trial.
