PREdelivery Placental Biomarkers- Pregnancy and Delivery Outcome
An observational study of Pregnancy Complications and Placental Insufficiency, run by Oslo University Hospital at 1 site in Norway.
Trial summary
The PREPPeD study proposes that predelivery placenta-derived maternal circulating biomarkers reflect placental health, capacity and ageing, and can help predict onset and complications of delivery both in complicated pregnancies as well as in clinically uncomplicated term/post-term pregnancies.

About this study
Official title: The PREPPeD Study: "PREdelivery Placental Biomarkers- Pregnancy and Delivery Outcome"
The PREPPeD study proposes that predelivery placenta-derived maternal circulating biomarkers reflect placental health, capacity and ageing, and can help predict onset and complications of delivery both in complicated pregnancies as well as in clinically uncomplicated term/post-term pregnancies.
Read the detailed description
The main aim of the PREPPeD study is to explore whether placental health, evaluated by maternal blood biomarkers in late pregnancy, correlates with delivery outcomes in both healthy and complicated pregnancies.

What is being measured
The primary outcome is the main question the study is designed to answer.
Fetal acidaemia
In neonates delivered by cesarean section (CS) without labour (defined as absence of regular uterine contractions):
Umbilical artery blood (transporting blood from the fetus to the placenta) pH<7.13 and arterial BD >10.0
In neonates from labored delivery (regardless of subsequent delivery method, vaginal or CS):
Umbilical artery blood pH<7.05 and arterial BD>14; OR Umbilical artery blood (or venous if arterial blood not available) lactate above Reference level for respective gestational age according to publication by Wiberg N et al ,BJOG 2008 (doi: 10.1111/j.1471-0528.2008.01707.x.)
Measured: Umbilical cord gas/lactate are sampled directly post partum within 45 min; data assessed throughout study period of 140 months
Newborn low Apgar score
<4 at 1 minute OR <7 at 5 minutes

Questions about this trial
What is this clinical trial studying?
An observational study of Pregnancy Complications and Placental Insufficiency, run by Oslo University Hospital at 1 site in Norway.

Who may be eligible to take part?
The sponsor lists 1 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 19 Dec 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Norway. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Meryam Sugulle, PhD, MD (+4722119800, uxsume@ous-hf.no), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Fetal acidaemia (time frame: Umbilical cord gas/lactate are sampled directly post partum within 45 min; data assessed throughout study period of 140 months). The study lists 9 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03100084, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Dec 2020; AzTrials last refreshed its copy on 7 Nov 2026.
