Early double low-dose aspirin to help prevent preeclampsia and miscarriage

Official title: Early Double Low-Dose Aspirin to Reduce Preeclampsia and Miscarriage: a Global Approach RCT

Funded at University of Pennsylvania · NIH-11380015 · Data updated 2026-11-12

A large clinical trial tests whether starting a daily 162 mg aspirin as soon as pregnancy is detected can reduce both preeclampsia and pregnancy loss in early pregnancy.

Who could benefit from this research

Could help

Pregnant people in the very early stages of pregnancy (from first positive pregnancy test up to about 6 weeks gestation) who are eligible for participation at participating sites.

Less likely to help

Some participants may not experience a difference in outcomes or may encounter side effects from aspirin.

What this research studies

This trial invites people who might become pregnant to enroll if they test positive early, with aspirin taken from the moment of detection to see if it lowers risk of preeclampsia and miscarriage. It uses a randomized design to compare daily aspirin at a higher initial dose with standard care, while monitoring pregnancy outcomes. Participants will be followed through early pregnancy to track outcomes and safety. The study is led by the University of Pennsylvania and involves clinical centers and advisory committees to guide the trial conduct.

Why it matters

Potential benefit: If successful, the approach could reduce serious pregnancy complications and improve chances of a healthy pregnancy.

How similar studies have gone: Previous evidence supports aspirin for preeclampsia prevention, with newer data exploring earlier initiation and higher doses; this trial aims to confirm and extend those findings.
