SAN CARLOS, Calif., Dec. 6, 2018 /PRNewswire/ -- Natera, Inc. (NASDAQ: NTRA), a leader in non-invasive genetic testing and the analysis of cell-free DNA, presented data from two studies this week at the 2018 San Antonio Breast Cancer Symposium (SABCS), demonstrating the ability of its Signatera™ RUO (research-use-only) circulating tumor DNA (ctDNA) assay to detect molecular residual disease (MRD) up to two years prior to clinical relapse and to predict treatment response in breast cancer.
Both breast cancer studies included a cross-section of patient subtypes, including HER2-positive, hormone receptor-positive, and triple-negative.
"Our outstanding performance using Signatera (RUO) in clinical studies to detect molecular residual disease and monitor treatment response across lung, bladder, and colon cancers continues in breast cancer," said Jimmy Lin, M.D., Ph.D., MHS, Natera's Chief Scientific Officer, Oncology. "We look forward to sharing this new data and discussing the implications for using Signatera more broadly in clinical trials for patient selection, prognostic evaluation, treatment response monitoring, and recurrence monitoring in the neoadjuvant, adjuvant, and metastatic settings."
"The consistently strong performance of this assay demonstrates that our unique approach is realizing the promise of personalized medicine in local-regionally advanced early-stage cancer management," said Alexey Aleshin, M.D., Oncology Medical Director, Natera. "The body of evidence is building, and we are excited to see these new results in breast cancer. This represents a key milestone in making our assay available for clinical practice and for use in novel neoadjuvant and adjuvant clinical trial designs."
About Signatera (Research-Use-Only)
Signatera (RUO) is the first ctDNA assay custom-built for treatment monitoring and molecular residual disease assessment. The Signatera (RUO) methodology differs from currently available liquid biopsy assays, which test for a panel of genes independent of an individual's tumor. Signatera (RUO) provides each patient with a customized blood test tailored to match the mutations found in that individual's tumor tissue, which maximizes sensitivity and specificity. 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 molecular residual disease, 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

*I-SPY 2 TRIAL stands for "Investigation of Serial studies to Predict Your Therapeutic Response with Imaging And moLecular analysis 2" (NCT01042379). The goal is to identify improved treatment regimens for subsets of patients on the basis of molecular characteristics (biomarker signatures) of their disease. New drugs enter the trial as those that have undergone testing complete their evaluation. Quantum Leap Healthcare Collaborative (QLHC) is the sponsor of the I-SPY 2 TRIAL, and is a 501C(3) charitable organization established in 2005 as a collaboration between medical researchers at University of California, San Francisco and Silicon Valley entrepreneurs.
