New combo therapy aims to prevent dangerous pregnancy condition
NCT ID NCT07361679
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether adding a blood thinner (low molecular weight heparin) to daily low-dose aspirin can prevent preeclampsia in pregnant women at high risk. Preeclampsia is a serious condition causing high blood pressure and organ damage. The trial will enroll 100 women early in pregnancy and compare the two treatments to see which works better.
