Natera Obtains Z-Codes for Signatera MRD and Treatment Monitoring Test in Oncology

Represents Key Reimbursement Milestone In Line with Planned Clinical Launch

SAN CARLOS, Calif., Jan. 4, 2019 /PRNewswire/ — Natera, Inc. (NASDAQ: NTRA), a global leader in non-invasive genetic testing and cell-free DNA, today announced the assignment of two Z-codes for the company’s Signatera™ test, in preparation for its planned clinical launch in Q2 2019. Signatera, when clinically available, is intended for use by oncologists to detect molecular residual disease (MRD) and monitor treatment response in cancer patients.

Two Z-codes were awarded, ZB8DC and ZB8DD, representing the initial and subsequent test orders for each patient. These codes will cover multiple cancer types, as the Signatera technology has shown consistent performance across multiple cancers, including lung, breast, colorectal, and bladder.

"The attainment of these Z-codes is an essential part of our reimbursement strategy and is in line with our planned clinical launch this year," said Solomon Moshkevich, Natera’s General Manager, Oncology and Transplant Businesses. "When it is launched, we expect that Signatera will become a powerful new tool in the oncologist’s arsenal for post-treatment MRD assessment, treatment response monitoring, and earlier detection of recurrence."

About Signatera™
Signatera is the first ctDNA assay custom-built for treatment monitoring and MRD assessment. The test is currently available for Research Use Only (RUO), until its clinical launch currently planned for Q2 2019. The Signatera methodology differs from currently available liquid biopsy assays, 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 RUO 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. A 2017 study demonstrated the Signatera RUO method’s ability to detect MRD, measure treatment response, and identify recurrence up to 11 months earlier than the standard of care for early stage non-small cell lung cancer (NSCLC) with 93 percent sensitivity and zero false positives.1 Additional research presented at the European Society for Medical Oncology 2018 Congress showed successful results from bladder and colorectal cancer studies, including median detection points of ctDNA that were 3.3 and 7.9 months, respectively, ahead of clinical relapse detection.2,3 In two studies presented at the 2018 San Antonio Breast Cancer Symposium (SABCS), Signatera RUO was able to detect MRD up to two years prior to clinical relapse and to predict treatment response in a cross-section of breast cancer patients, including those who were HER-2 positive, hormone receptor-positive and triple negative.4,5 Based on numerous studies across multiple cancer types, a positive Signatera RUO result without further treatment has predicted clinical relapse nearly 100% of the time.1-5
