Could earlier aspirin save lives in sickle cell pregnancies?
NCT ID NCT06417411
First seen Jul 06, 2026 · Last updated Jul 07, 2026 · Updated 1 time
Summary
This study looks at whether starting daily low-dose aspirin in the first trimester (weeks 1–12) is safer and more effective than starting in the second trimester (weeks 13–27) for pregnant women with sickle cell disease. Researchers will track maternal deaths, preterm births, and late miscarriages. The goal is to find the best timing to reduce serious pregnancy complications in this high-risk group.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Aspirin 100 mg
- What this could lead to
- If starting aspirin earlier reduces complications, it could offer a simple, low-cost way to improve pregnancy outcomes in women with sickle cell disease.
- What could go wrong
- This is an early-phase study, so results may not be conclusive. Aspirin carries bleeding risks, and the benefit may be small or absent.
