  • Clinically confirmed singleton pregnancy
  • Gestational age between 10 weeks, 0 days and 20 weeks, 0 days
  • Referred for prenatal genetic counseling due to increased risk for fetal aneuploidy (advanced maternal age (AMA ≥ 35 years at delivery, high-risk prenatal screen result, abnormal fetal ultrasound finding consistent with fetal aneuploidy, and/or history of prior affected pregnancy for fetal aneuploidy)
  • Pregnancy records accessible and available for data collection (e.g., results from screening, ultrasound examinations, invasive prenatal procedures if performed, and infant hospital discharge exam)
  • Able to provide consent for participation using language-appropriate forms

Who cannot join

  • Invasive prenatal procedure (amniocentesis or CVS) already performed

About this study

This is a prospective, single-institution observational study to be conducted at 4 clinics within the Southern California Permanente Medical Group. Pregnant women who present for prenatal genetic counseling at the designated clinics and who meet study eligibility criteria will be offered the option of the verifi® prenatal test by a trained, licensed and certified genetic counselor (GC) . Women who elect the verifi® prenatal test will have a blood sample drawn by peripheral venipuncture that will be sent to the Verinata Health CAP-accredited clinical laboratory (Redwood City, CA). Results will be reported to the ordering health care provider by the laboratory within 8-10 business days and will be shared with the subject by their provider. Subject care and decision-making following NIPT result will be clinically managed by the provider with his/her subject and is not dictated by the study protocol. All eligible women who provide informed consent, whether they elect or decline NIPT will be asked to complete a short questionnaire on their views of prenatal testing. The uptake of invasive prenatal procedures (CVS and/or amniocentesis) by the total prospective cohort will be collected through review of electronic medical records (EMR). A historical cohort with matched demographic and pre-test indications to the prospective cohort will be identified from the EMR for comparison in the primary analysis.

What is being measured

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

  1. Invasive prenatal procedures rate measure by the occurance of chorionic villus sampling (CVS) and/or amniocentesis

    The primary objective of this study is to compare the rate of uptake of invasive prenatal procedures (chorionic villus sampling (CVS) or amniocentesis) between a prospectively enrolled cohort of pregnant women at high-risk for fetal aneuploidy who are offered noninvasive prenatal testing (NIPT; verifi® prenatal test) and a historical cohort matched for demographics and pre-test risk indications. The prospective group will include both those who accept NIPT and those who decline NIPT, but are willing to consent and complete a brief questionnaire.

    Measured: Enrolled women will be evaluated on or before Gestational Age: Wk 28

Secondary outcomes (1)
  1. Preferences of pregnant women on prenatal testing by completion of preference questionnaire.

    The secondary objective is to collect views/preferences of pregnant women on prenatal testing for fetal chromosomal abnormalities and compare results of eligible women who accept versus those who decline NIPT during the enrollment period.

    Measured: Evaluated at time of enrollment

Questions about this trial

What is this clinical trial studying?

An observational study of High Risk Pregnancy, run by Verinata Health, Inc. at 4 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 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: finished, as of the sponsor's last update on 26 Sep 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 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?

Invasive prenatal procedures rate measure by the occurance of chorionic villus sampling (CVS) and/or amniocentesis (time frame: Enrolled women will be evaluated on or before Gestational Age: Wk 28). 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 NCT01708746, which also lists 2 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 Sep 2014.
