About this study

Official title: Collection of Whole Blood Specimens From Pregnant Women at Increased Risk of Fetal Chromosomal Abnormality for Use in Development of a Noninvasive Prenatal Test in the Detection of the Relative Quantity of Chromosomal Material in Circulating Cell-Free DNA Extracted From Maternal Plasma

The specimen collection is designed for the purpose of the development of a noninvasive prenatal test for T21.

Read the detailed description

To collect specimens for the purpose of developing a prenatal aneuploidy test. The test will analyze circulating cell free fetal (ccff) nucleic acid from blood samples from pregnant women who have an increased risk indicator/s for fetal chromosomal aneuploidy and are undergoing invasive prenatal diagnosis by chorionic villus sampling (CVS) and/or genetic amniocentesis. The results of the ccff aneuploidy test will be compared to the chromosomal analysis obtained via CVS or genetic amniocentesis.

Questions about this trial

What is this clinical trial studying?

An observational study of Down Syndrome and Fetal Aneuploidy, run by Sequenom, Inc. at 14 sites in 2 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 6 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: looking for participants now, as of the sponsor's last update on 9 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 14 sites in United States, Canada. 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?

This study is still under way. Results are not available in the source record yet.

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

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Collect samples and data for assay validation. (time frame: 9-24 weeks of gestatational age). 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 9 Sep 2026.
