Monitoring therapeutic response during pregnancy for preeclampsia

Developing Extracellular Vesicle Based MPRINT Translational Resource Platform for Monitoring Therapeutics Response During Pregnancy

Observational Ohio State University · NCT06249178

This study is testing if blood samples from pregnant people at risk for preeclampsia can help us understand how well aspirin works in protecting both the mother and baby during pregnancy.

What this trial studies

This observational cohort study aims to analyze the extracellular vesicle (EV) proteome profiles of pregnant individuals at risk for preeclampsia who are receiving aspirin treatment. Participants will provide blood samples up to four times during their pregnancy to generate proteomic data that could help identify distinct maternal and fetal EV profiles associated with aspirin use. The study seeks to develop and validate a multi-marker panel to monitor placental function and assess the effectiveness of aspirin in preventing preeclampsia. By focusing on placental-specific biomarkers, the research addresses the gap in therapeutic evaluations for pregnant individuals.

Who should consider this trial

Good fit: Ideal candidates include pregnant individuals aged 18 and older, enrolled before 16 weeks of gestation, who are at high or moderate risk for hypertensive disorders of pregnancy.

Not a fit: Patients who are not pregnant or those with multiple gestations may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved monitoring and management of preeclampsia in pregnant individuals, enhancing maternal and fetal health outcomes.

How similar studies have performed: While the approach of using extracellular vesicle profiling is innovative, prior studies have shown potential correlations between aspirin use and pregnancy outcomes, indicating a promising avenue for further exploration.
