Major trial tests if early aspirin stop is safe for Moms-to-Be

NCT ID NCT07665853

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study looks at whether pregnant women at high risk for preeclampsia can safely stop taking daily aspirin at 24-28 weeks instead of continuing until 36 weeks. Over 15,000 women across Europe and Africa will be randomly assigned to stop or continue aspirin. The goal is to see if stopping early is just as effective at preventing preterm preeclampsia while reducing side effects like bleeding.

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)

What this could lead to

If successful, this could show that stopping aspirin earlier is just as effective for preventing preeclampsia, reducing unnecessary medication and side effects for many pregnant women.

What could go wrong

This is a large phase 3 trial, but it's testing a non-inferiority hypothesis—meaning it aims to prove stopping early is not worse than continuing. There's a risk that stopping earlier might slightly increase preeclampsia cases in certain populations, especially women of African origin.
