Trial summary

Erythropoietin (EPO) is a glycoprotein hormone with a molecular weight of 30.4 kDa, responsible for regulating erythropoiesis in adults, newborns and fetuses. During pregnancy, the concentration of maternal serum EPO increases linearly to allow for effective erythropoiesis over time. Read more about this study

About this study

Erythropoietin (EPO) is a glycoprotein hormone with a molecular weight of 30.4 kDa, responsible for regulating erythropoiesis in adults, newborns and fetuses. During pregnancy, the concentration of maternal serum EPO increases linearly to allow for effective erythropoiesis over time. In the fetus, in the first 30 weeks of gestation, the liver is the main synthetic organ. Thereafter, there is a progressive transfer of the synthesis of EPO to the kidneys. In the long term, under normal conditions of oxygenation, the fetal synthesis of EPO is mainly ensured by the kidney.

Because of the impossibility of making EPO tissue reserves and the inability of EPO to pass the placental barrier, the concentration of circulating EPO in the fetus reflects the balance between production and elimination. During the last trimester of pregnancy, in the absence of patent hypoxia, fetal concentrations of circulating EPO are between 10 and 50 mIU /ml, while in amniotic fluid the EPO is found at lower concentrations, between 2 and 20 mIU /ml.

In adults, EPO synthesis is primarily renal, and incidentally hepatic, even if in certain pathological situations (end-stage kidney disease or polycystosis) the liver is able to take over and synthesize EPO with an electrophoretic profile similar to that of the EPO from the umbilical cord, but often in insufficient quantities.

The objective of this study is to describe the forms of EPO in newborns and to compare possible iso-forms with those of adults.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. EPO concentration UI/L

    Measured: Baseline

  2. Electrophoretic profile of EPO

    It is an indicator of glycosylation differences (more complex forms including sialic acids are more acidic, less complex forms are more basic)

    Measured: Baseline

Questions about this trial

What is this clinical trial studying?

An observational study of Newborn Infant and Child Under One Year of Age, run by Centre Hospitalier Universitaire Dijon at 1 site in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 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 21 May 2019. 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 France. 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 François Girodon (03.80.29.30.47 ext. +33, francois.girodon@chu-dijon.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

EPO concentration UI/L (time frame: Baseline). The study lists 2 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 NCT03957863, 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 21 May 2019.
