Natera Selected for Circulating Tumor DNA Study in Colorectal Cancer
Second Study with Denmark's Aarhus University to Leverage Signatera™ (RUO) Personalized ctDNA Technology

SAN CARLOS, Calif., Nov. 6, 2017 /PRNewswire/ -- Natera, Inc., (NASDAQ: NTRA), a global leader in cell-free DNA testing, today announced a second research collaboration with Denmark's Aarhus University utilizing the company's Signatera™ (RUO) technology to evaluate ctDNA as a useful biomarker for detecting minimal residual disease, treatment response, and disease recurrence in colorectal cancer patients. The company previously announced that the university would be using the Signatera™ technology in a bladder cancer study.

This second study will evaluate 130 patients with stage I-III colorectal cancer previously treated with surgery and adjuvant chemotherapy, and then monitored longitudinally with blood samples drawn approximately every three months for up to 36 months. Sequencing data from each individual's tumor will be provided by Aarhus University and analyzed using the Signatera™ proprietary bioinformatics pipeline, resulting in custom ctDNA assays designed for each individual. The objective of the study is to determine the relationship between post-surgical ctDNA levels, minimal residual disease, disease relapse, and adjuvant therapeutic response. Study results are expected in 2018, which will help support the launch of Signatera in the clinical setting.

Colorectal cancer is the fourth most common cancer diagnosed in the United States and has the second highest mortality rate among all cancer types.1 In 2017, more than 135,000 people will be diagnosed with colorectal cancer2, with five-year prevalence of 385,000.3 Multiple studies have shown that early detection of disease relapse can help improve outcomes.4

"We are pleased to expand our research partnership with Natera to include this study of ctDNA in colorectal cancer," said Claus Lindbjerg Andersen, PhD, Professor, Department of Molecular Medicine at Aarhus University. "Better diagnostic tools in the adjuvant setting are needed, especially with the proven benefit of earlier detection and treatment of disease relapse. We expect that this study of circulating tumor DNA will provide new insights that may help improve patient outcomes."

"We look forward to working with Aarhus University on this important research project," said Jimmy Lin, MD, PhD, MHS, Chief Scientific Officer, Oncology, at Natera. "This study will help define whether personalized ctDNA analysis can improve diagnosis and management in early stage colorectal cancer."

Signatera™ (RUO) was recently launched for use by oncology researchers and biopharmaceutical companies, and is expected to be available for clinical use next year. The technology differs from currently available liquid biopsy assays, which test for a generic panel of genes independent of an individual's tumor. It 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.

A recent study of patients with early stage non-small cell lung cancer (NSCLC) showed the value of Natera's customized ctDNA analysis for use in cancer research. The study, which was featured on the cover of the journal Nature, demonstrated the method's potential to detect residual disease, measure treatment response, and identify recurrence up to 11 months earlier than the standard of care.5
