Could a higher aspirin dose stop preterm births? large trial launches

NCT ID NCT06980025

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tests whether taking 162 mg of aspirin daily (two baby aspirins) is better than the usual 81 mg for preventing another early birth. It includes 1,800 pregnant women who have previously delivered before 35 weeks. Participants start the medicine between 10 and 15 weeks of pregnancy and continue until nearly 37 weeks. The goal is to see if the higher dose reduces the chance of preterm delivery or fetal death before 35 weeks.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

Aspirin

What this could lead to

If successful, this could establish a higher dose of aspirin as a standard to prevent preterm birth in women with a history of early delivery.

What could go wrong

This is a phase 3 trial, but it only compares two aspirin doses—not a placebo—so the benefit over no treatment is already assumed. Results may not apply to all women, and aspirin carries bleeding risks.
