Clinical Evaluation of the SEQureDx Trisomy Test in Low Risk Pregnancies

This study has been completed.

Sequenom, Inc. Identifier:
First received: May 9, 2012
Last updated: April 18, 2016
Last verified: April 2016
Pregnant women with low risk indicators for fetal chromosomal aneuploidy will be enrolled. Study blood will be collected in the first or second trimester at a scheduled prenatal screening visit, processed to plasma, and stored frozen until analysis. Each pregnancy will be followed until delivery and the birth outcome recorded.

Condition Intervention
Down Syndrome
Noninvasive Prenatal Screening
Device: SEQureDx Trisomy Test

Study Type: Observational
Study Design: Observational Model: Case-Only
Time Perspective: Prospective
Official Title: A Clinical Study to Evaluate the Relative Clinical Specificity Performance of the SEQureDx Trisomy Test in Pregnant Women at Low Risk for Fetal Chromosomal Aneuploidy

Further study details as provided by Sequenom, Inc.:

Primary Outcome Measures:
  • Estimate the false positive rate of SEQureDx Trisomy 21 Test [ Time Frame: pregnancy outcome ]

Biospecimen Retention:   Samples With DNA
Whole blood specimens will be collected and processed to plasma. DNA will be extracted from the plasma.

Enrollment: 3333
Study Start Date: July 2012
Study Completion Date: December 2015
Primary Completion Date: February 2014 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
low risk pregnancies Device: SEQureDx Trisomy Test
Plasma samples obtained from maternal blood will be tested using the SEQureDx Trisomy Test, an in vitro diagnostic test that measures circulating cell-free fetal DNA. The test detects the relative quantity of chromosome 21, which is associated with trisomy 21.
