Natera to Present Latest Signatera™ MRD Data in Colorectal and Pancreatic Cancers at the ASCO GI Symposium 2022, and Host Special Investor Call

Oral presentations to include largest analysis to date from the prospective CIRCULATE-Japan study and results from first study showing clinical utility of Signatera in pancreatic cancer

AUSTIN, Texas, Jan. 19, 2022 /PRNewswire/ — Natera, Inc. (NASDAQ: NTRA), a leader in personalized genetic testing and diagnostics, today announced the company, along with its collaborators, will present new data on Natera’s personalized, tumor-informed molecular residual disease (MRD) test, Signatera, at the American Society of Clinical Oncology’s 2022 Gastrointestinal Cancers Symposium (ASCO GI), taking place January 20 – 22, 2022.

Natera has two oral presentations and four collaborative poster presentations highlighting clinical findings on the performance of Signatera across colorectal (CRC), pancreatic and anal cancers. The oral presentations include an interim analysis from the GALAXY cohort of the CIRCULATE-Japan trial, based on 12-month outcomes from more than 1,000 patients, demonstrating how MRD testing can help predict treatment benefit for CRC patients post-surgery, regardless of stage. A second oral presentation addresses results from the first major study on the utility of MRD testing for patients with pancreatic cancer, compared to the standard of care biomarker CA19-9.

"The predictive data coming out of CIRCULATE-Japan is exceptional, and we think it has the potential to transform clinical practice in CRC," said Solomon Moshkevich, general manager of oncology at Natera. "We also look forward to presenting high-impact data from our pancreatic and other GI studies, further expanding the pan-cancer utility of Signatera’s personalized and tumor-informed method."

Natera and its collaborators will present the following studies:

About Signatera

Signatera is a custom-built circulating tumor DNA (ctDNA) test for treatment monitoring and molecular residual disease (MRD) assessment in patients previously diagnosed with cancer. The test is available for both clinical and research use, and has been granted three Breakthrough Device Designations by the FDA for multiple cancer types and indications. The Signatera test is personalized and tumor-informed, providing each individual with a customized blood test tailored to fit the unique signature of clonal mutations found in that individual’s tumor. This maximizes Signatera’s accuracy for detecting the presence or absence of residual disease in a blood sample, even at levels down to a single tumor molecule in a tube of blood. Signatera is intended to detect and assess how much cancer is left in the body, to identify recurrence earlier and to help optimize treatment decisions.
