About this study

Official title: Development of Non-invasive Prenatal Diagnostic Test Based on Fetal DNA Isolated From Maternal Blood

The primary purpose of this study is to collect maternal blood samples from pregnant women to develop a non-invasive prenatal diagnostic test based on fetal DNA isolated from maternal blood.

Read the detailed description

The investigators will seek to enroll subjects to collect the following types of samples:

  • Up to 2,000 maternal blood samples along with their corresponding paternal blood, buccal or saliva samples (1,000 required for final analysis).
  • Up to 200 maternal blood samples from carrying a fetus with a confirmed chromosomal abnormality or genetic disorder, along with their corresponding paternal blood, buccal or saliva samples (50 required for final analysis). For women who opted for termination, a genetic sample of the fetus may also be collected.
  • Up to 1,000 buccal or saliva samples from paternal grandfathers and/or the biological father's brothers.
  • Up to 1,000 cord, buccal or saliva samples from the born children.
  • Up to 40 blood samples (20 non-pregnant females and 20 males) from healthy volunteers (20 required for final analysis)
  • Up to 400 blood samples from women undergoing D\&C procedure following a miscarriage along with corresponding paternal blood (or buccal or saliva samples) (200 required for final analysis).

What participants receive

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

  • Blood drawProcedure or surgery

    Also called Non-Invasive Prenatal Diagnosis, NIPD

    Blood is drawn at the appropriate time given their cohort inclusion.

  • Cheek swab/Saliva SamplingProcedure or surgery

    Also called Non-Invasive Prenatal Diagnosis, NIPD

    In lieu of blood draw, male relatives may donate cheek swab or saliva sample. Children born to participating women can donate cheek swab or saliva sample soon after birth.

What is being measured

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

  1. Fetal chromosome abnormality from a maternal plasma sample

    Maternal plasma will be drawn at the time at which they present while pregnant as long as they are at least 6 weeks along. Additional samples (for confirmation of chromosome makeup) may also be drawn on that fetus when fetal sampling is possible (termination, miscarriage) or on the child at or shortly after birth.

    Measured: From date of initial blood draw until the date of pregnancy end (miscarriage/termination) or time of birth, whichever came first, assessed up to 10 months

Questions about this trial

What is this clinical trial studying?

An observational study of Chromosome 13 Aneuploidy and Chromosome 18 Aneuploidy, run by Natera, Inc. at 1 site 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 6 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: finished, as of the sponsor's last update on 2 Jul 2013. 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 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?

Fetal chromosome abnormality from a maternal plasma sample (time frame: From date of initial blood draw until the date of pregnancy end (miscarriage/termination) or time of birth, whichever came first, assessed up to 10 months). 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 2 Jul 2013.
