Recruiting PHASE4 Hypertensive Disorders of Pregnancy

Prevention study for Hypertensive Disorders of Pregnancy

Official title Effectiveness of Two Aspirin Doses for Prevention of Hypertensive Disorders of Pregnancy: ASPIRIN TRIAL

ClinicalTrials.gov ID: NCT06468202

What this study is testing

What is Aspirin 81 mg?

Aspirin 81 mg is an investigational medicine, being studied as a potential treatment for hypertensive disorders of pregnancy.

Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.

What it's testing
The overall goal of this large, pragmatic, comparative effectiveness trial is to test the hypothesis that among at-risk individuals, 162 mg/day aspirin is superior to 81 mg/day in preventing Hypertensive disorders of pregnancy (HDP), and that there are multiple factors associated with adherence with aspirin therapy that will be important to identify to enable optimal implementation of study findings and population-level benefits.
