Can a higher aspirin dose shield High-Risk pregnancies from preeclampsia?
NCT ID NCT07779057
First seen Aug 21, 2026 · Last updated Aug 21, 2026
Summary
This trial tests whether a higher dose of aspirin (150 mg) prevents preeclampsia better than the standard low dose (75 mg) in pregnant women at high risk. Participants take their assigned dose nightly from early pregnancy until 36 weeks, and researchers track who develops preeclampsia, stillbirth rates, and newborn birth weight. The goal is to find the most effective aspirin dose to protect 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
- Aspirin (acetylsalicylic acid) taken orally once daily at bedtime from 11-14 weeks of pregnancy until 36 weeks
- What this could lead to
- If a higher dose works better, it could offer a simple, low-cost way to reduce preeclampsia risk in high-risk pregnancies, potentially improving outcomes for mothers and babies.
- What could go wrong
- This is a small, early-phase trial, so results may not be conclusive. Higher-dose aspirin may increase bleeding risk, and the benefit over the standard dose is not yet proven.
