Molecular Screening Method for Preeclampsia (PREMOM)

The hypothesis is that there is a unique molecular profile in peripheral blood specific to women who develop EOPE that allow an early assess woman´s risk of developing this pregnancy complication. The purposed study is a biomedical, prospective, multicentre, case-control aimed to determine the predictive value and diagnostic precision of the maternal blood molecular profile for the early screening of EOPE. Late-onset preeclampsia (LOPE) and other pregnancy complications (such as preterm birth, intrauterine growth restriction, gestational diabetes, placenta previa, placental abruption, placenta accreta, premature rupture of preterm membranes, antepartum fetal death, uterine rupture and previous vasa, among others) could be analysed as a secondary outcome. Subjects will be 9585 pregnant women recruited between 9 and 14 gestational weeks. Participants will provide peripheral blood sample at three different times during pregnancy to be characterised at molecular level in the iPremom laboratories (Igenomix Preeclampsia SLU) after their obstetric outcome was known. Once the 50% of the total enrolment is achieved, an interim analysis will be conducted by an independent external committee. Data will be registered in an electronic Case Report Form (eCRF) specifically designed for this study. Monitoring activities and data verification will be performed during the whole study to ensure data quality, integrity and transparency. The total estimated duration of the study is 30 months, of which the first 18 months will correspond to the recruitment period of the participants.
