Natera Presents Outcomes Data at SMFM Annual Meeting Showing Strong Clinical Performance of Its SNP-Based Non-Invasive Prenatal Test

Study Shows High Positive Predictive Values in Detecting Common Chromosomal Aneuploidies in All Women, Including Women Under 35 Years of Age

SAN CARLOS, Calif., Feb. 19, 2019 /PRNewswire/ -- Natera, Inc. (NASDAQ: NTRA), a global leader in cell-free DNA testing, presented data at the Society for Maternal-Fetal Medicine (SMFM) Annual Pregnancy Meeting showing strong clinical performance of its Panorama® SNP-based non-invasive prenatal test (NIPT) to detect common chromosomal aneuploidies (genetic abnormalities) in all women, including women under 35 years of age, with high accuracy.1

The primary objective of the study was to prospectively analyze the clinical performance of the company's NIPT as a part of its rigorous laboratory-based quality assurance program. Fetal outcome data was solicited from women who received a high-risk result from over 900,000 Panorama tests performed between 2013 and 2017. The positive predictive value (PPV) in this cohort was 95.2% for trisomy 21 (Down syndrome), 93.5% for trisomy 18 (Edwards syndrome), 77.9% for trisomy 13 (Patau syndrome), and 86.7% for monosomy X. The PPV was similar for both high-risk (maternal age ≥ 35 yrs) and average risk (< 35 yrs) pregnancies, consistent with a previous study (n=17,885).2

"The high positive predictive values demonstrated in this study once again validate the utility of NIPT as a primary prenatal screening tool in the management of all pregnancies, including women under 35 years of age," said Dr. Kimberly A. Martin, Natera Vice President, Global Women's Health. "We believe this study continues to reaffirm NIPT as the most accurate screening option for pregnant women of all ages."

About Panorama®
Panorama reveals a baby's risk for severe genetic disorders as early as nine weeks into pregnancy. The test uses a unique single-nucleotide polymorphism (SNP)-based technology to analyze fetal/placental DNA obtained through a blood draw from the mother. It is the only test that differentiates between maternal and fetal DNA in the relevant chromosomes of interest. The test also screens twin pregnancies for zygosity, fetal sex of each baby, and identifies risk for more genetic conditions in twin pregnancies than any other NIPT. Panorama is one of several genetic screening tests from Natera designed to help families on the path to parenthood.

This test was developed by Natera, Inc., a laboratory certified under the Clinical Laboratory Improvement Amendments (CLIA). This test has not been cleared or approved by the U.S. Food and Drug Administration (FDA). Although FDA does not currently clear or approve laboratory-developed tests in the U.S., certification of the laboratory is required under CLIA to ensure the quality and validity of the tests.
