FDA Grants Breakthrough Device Designation to Natera's Signatera Test

SAN CARLOS, Calif., May 6, 2019 /PRNewswire/ -- Natera, Inc. (NASDAQ: NTRA) today announced that the U.S. Food and Drug Administration (FDA) has granted "Breakthrough Device" designation for its Signatera™ test for use in the post-surgical detection and quantification of circulating tumor DNA (ctDNA) in the blood of patients previously diagnosed with certain types of cancer and in combination with certain drugs. The designation will help accelerate FDA assessment and review of Signatera as an in vitro diagnostic for use in pharmaceutical trials.

Signatera is the first ctDNA test custom-built for each patient based on the unique mutations in an individual patient's tumor. Signatera has been shown in numerous clinical studies, across non-small cell lung, bladder, breast and colorectal cancers, to identify molecular residual disease significantly earlier (up to two years earlier) than standard imaging.^1-5 Studies have also shown that Signatera test status is the most significant predictor of long-term patient outcomes after surgery and treatment, relative to all other clinical and pathological factors.^1-5

"This Breakthrough Device designation is a significant step forward in our commercial strategy, helping to clear the path for Natera to participate in registrational drug trials that use Signatera for patient selection and study enrichment," said Solomon Moshkevich, Natera's General Manager, Oncology and Transplant Businesses. "This milestone directly supports our stated goal of achieving $40 to $50 million in cumulative pharma contracts by the end of 2019."

"We are delighted to work with the FDA in the context of the Breakthrough Device program," said Steve Chapman, Natera's CEO. "This designation validates our belief that Signatera will truly change the way cancer patients are diagnosed and treated, ultimately leading to better treatment decisions and improved clinical outcomes."

About Signatera™ 
Signatera is the first circulating tumor DNA (ctDNA) test custom-built for molecular treatment monitoring and molecular residual disease (MRD) assessment. The test is available for research use only (RUO) until its clinical launch planned for Q2 2019. The Signatera methodology differs from currently available liquid biopsy tests, which test for a fixed panel of therapeutically relevant genes. Signatera provides each individual with a customized blood test tailored to match the clonal mutations found in that individual's tumor tissue. This maximizes accuracy for detecting the presence or absence of MRD in a blood sample, even at levels down to a single mutant molecule in a tube of blood. Signatera also allows researchers to track additional mutations of interest, up to several hundred mutations, for clinical studies.

The body of evidence on the utility of Signatera is growing, with multiple studies demonstrating the Signatera RUO method's ability to detect MRD, measure treatment response, and identify recurrence months or years earlier than the standard of care for a variety of cancer types, including breast cancer, early stage non-small cell lung cancer, bladder cancer, and colorectal cancer.^1-5 Based on numerous studies across multiple cancer types, a positive Signatera RUO result without further treatment has predicted clinical relapse over 98 percent of the time.^1-5
