About this study

The objective of this project is to evaluate clinical significance of measuring maternal blood estriol levels, after the administration of antenatal corticosteroids to enhance lung maturity. The investigators will test for associations of the change in maternal estriol with the development of respiratory distress syndrome. The investigators are also interested in determining whether salivary estriol is a valid surrogate to estriol blood assays. In addition the investigators will correlate these changes to pharmacokinetic (PK), pharmacodynamics (PD), and pharmacogenetic measures of betamethasone administration and fetal respiratory outcome

Read the detailed description

We will obtain serum and saliva for estriol measurement before or within 2 hours of antenatal corticosteroid administration and about 24 hours after each dose is given.

Women who consent to an optional PK portion of the study will have plasma samples obtained pre-dose and then on a schedule of approximately 0.5-2, 4-8, 10-15, 22-24 hours after the first dose and then 6-8, 24, and 48 hours after the 2nd dose. One sample will be collected in each of these times.

A sample of whole blood will be obtained for DNA isolation. At the time of delivery, umbilical cord blood will be collected before being discarded for DNA and plasma. If we are unable to obtain umbilical cord blood, a buccal swab will be collected from the baby for DNA extraction.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

Study groups in NCT02112513
Study groupRoleWhat they receive
salivary estriol measurementSerum Estriol measurement via different assays is complex, expensive, labor intensive, time consuming, and generally performed at specific reference labs. Salivary Estriol level is an ideal potential surrogate for serum Estriol. It is convenient, non-invasive, and expedient. It may not, however, be as sensitive as serum estriol concentrations at detecting the association with glucocorticoid response. This study will collect both samples to determine which one is better suited for clinical use in this condition.
serum estriol measurewe will determine if changes in maternal serum estriol represent a biomarker of response to antenatal corticosteroids as evidenced by neonatal development of RDS
Betamethasone pharmacokineticwe will determine if pharmacokinetic parameters and neonatal outcomes after antenatal corticosteroid use are associated with genetic polymorphisms in drug metabolizing enzymes, transporters, and steroid pathway genes
betamethasone concentration and geneticswe will determine if maternal betamethasone concentrations and genetics are associated with maternal estriol changes or RDS development

What is being measured

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

  1. Respiratory distress syndrome

    Respiratory Distress Syndrome is diagnosed clinically, by need for mechanical ventilation and oxygen for at least 48 hours, and the presence of radiologic chest findings.

    Measured: At least 30 days after delivery, the maternal and neonatal charts will be reviewed

Questions about this trial

What is this clinical trial studying?

An observational study of Neonatal Respiratory Distress Syndrome, run by Indiana University at 2 sites in United States.

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 5 inclusion and 3 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: finished, as of the sponsor's last update on 28 Feb 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Respiratory distress syndrome (time frame: At least 30 days after delivery, the maternal and neonatal charts will be reviewed). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 28 Feb 2019.
