About this study
Official title: Development of Non-invasive Prenatal Diagnostic Test for Multiple Gestation Pregnancies Based on Fetal DNA Isolated From Maternal Blood
The objectives of the clinical study are to demonstrate the accuracy of our new NATUS diagnostic method to determine the genetic health of the developing fetuses in a multiple gestation pregnancy from a maternal blood sample. The long term goal of this study will be the development of a method of minimally invasive prenatal diagnosis that has a higher sensitivity and lower false positive rate in the intended population (e.g. multiple gestation pregnancies) than any currently available screening tests. This will result in fewer unnecessary amniocenteses and CVS procedures, which are associated with a risk of miscarriage.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Multiple high risk gestation pregnancies | women pregnant with twins or triplets at high risk for aneuploidy | |
| Multiple low risk gestation pregnancies | women pregnant with twins or triplets at low risk for aneuploidy |
What is being measured
The primary outcome is the main question the study is designed to answer.
The primary outcome will be to confirm the diagnostic capability of NATUS risk results classified as positive result for aneuploidy, negative result for aneuploidy or 'no call.'
The chromosomal status will be determined from the CVS or amniocentesis results, if available. A cheek swab or saliva sample will be collected from live-born children if there are no CVS or amniocentesis results.
Measured: 2 years

Questions about this trial
What is this clinical trial studying?
An observational study of Trisomy 13 and Trisomy 18, run by Natera, Inc. at 8 sites in 3 countries.
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 4 inclusion and 2 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 26 Aug 2019. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 8 sites in United States, India, Malaysia. 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?
The primary outcome will be to confirm the diagnostic capability of NATUS risk results classified as positive result for aneuploidy, negative result for aneuploidy or 'no call.' (time frame: 2 years). 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 NCT02278536, which also lists 8 linked publications.
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 26 Aug 2019.
