Natera Announces Plans to Commercialize Tumor Whole Exome Sequencing from Plasma

Represents Next Advancement in Company's Innovative Oncology ctDNA Program

SAN CARLOS, Calif., April 10, 2019 /PRNewswire/ — Natera, Inc. (NASDAQ: NTRA) Natera, a leader in cell-free DNA testing, today announced plans to commercialize a research-use-only (RUO) service for whole exome sequencing (WES) of circulating tumor DNA, using plasma samples from patients with cancer. The new service is expected to be available in the second half of 2019.

The assay does not require tumor tissue and will interrogate approximately 20,000 genes from circulating tumor DNA (ctDNA) to detect somatic mutations, representing a significant increase in coverage over most commercially available fixed liquid biopsy panels. There are multiple benefits to the new plasma exome sequencing offering, including the ability to design Signatera™ assays when tissue is not available. The assay may also allow researchers to characterize resistance mutations, actionable mutations, neoantigens, and tumor evolution. Finally, this capability will enhance Natera’s oncology database by generating valuable new data about tumor evolution over time.

The plasma exome service can be ordered as a stand-alone assay, or reflexively for Signatera ctDNA-positive cases. Many researchers want a comprehensive view of tumor evolution in order to link to treatments and outcomes, but it is very expensive to conduct a comprehensive analysis in early-stage or adjuvant disease, where tumor DNA is often not detectable in the plasma. With the combined service, researchers can first use Signatera to monitor patients for the presence or absence of ctDNA, and for positive patients they can reflex to a plasma exome to characterize tumor evolution using the same exact DNA library sample.

The first of multiple publications has been accepted in a top peer-reviewed journal and is expected to be published this quarter. Initial data has shown concordance between WES from tissue and plasma, and also strong concordance between WES and Signatera (RUO). "This exciting capability grows out of our deep molecular and bioinformatics expertise, and optimized sample and library preparation methods which consistently deliver a high yield of cell-free DNA molecules," said Bernhard Zimmermann, Natera Vice President, Research and Development. "This expertise will enable multiple new research applications in oncology."   

"The plasma exome capability adds an important component to our suite of services for cancer researchers," said Eric Lindquist, Natera Vice President, Oncology Business Development. "We are pleased with the significant momentum in our pharma business and believe we are on track to achieve our goal of $40 to $50 million in cumulative contracted value. Our combined offerings enable us to access the approximately $21 billion ctDNA molecular residual disease and liquid biopsy market in a very competitive manner."

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.
