Screening and planned delivery to prevent preeclampsia at term

Official title: Protocol of the PE37 Study: A Multicenter Randomized Trial of Screening With sFlt1/PlGF and Planned Delivery to Prevent Preeclampsia at Term

Run by Fundació Institut de Recerca de l'Hospital de la Santa Creu i Sant Pau · NCT04766866 · Data updated 2026-11-12

This study is testing a new blood test to see if it can help predict preeclampsia in first-time pregnant women and if inducing labor early can lower the chances of complications for both mom and baby.

Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are nulliparous women over 18 years old with singleton pregnancies between 35.0 and 36.6 weeks of gestation.

Probably not a fit

Patients with fetuses/neonates that have major malformations or genetic anomalies, or those suspected of fetal growth restriction, may not benefit from this study.

What this trial studies

This study aims to evaluate a single-step screening method using the sFlt1/PlGF ratio in maternal blood at 35-36 weeks of gestation to predict term preeclampsia (PE). If detected, the study proposes to induce labor from 37 weeks to reduce the prevalence of term PE without increasing cesarean section rates or adverse neonatal outcomes. The approach is designed to be pragmatic and applicable in various healthcare settings, particularly in those with limited resources. The study focuses on nulliparous women with singleton pregnancies who meet specific eligibility criteria.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the incidence of term preeclampsia and improve maternal and neonatal outcomes.

How similar studies have gone: Previous studies have shown promising results with similar screening approaches, indicating potential for success in this novel intervention.
