Natera, Inc. (NASDAQ: NTRA), a global leader in cell-free DNA testing, today announced the publication of a new study in Nature Medicine, which demonstrates the ability of the SignateraTM molecular residual disease (MRD) test to identify patients with stage II-IV colorectal cancer (CRC) who are at an increased risk of recurrence and predict who is likely to benefit from adjuvant chemotherapy (ACT). With this study, data supporting the clinical validity and utility of Signatera has now been published in 40 peer-reviewed publications.
The paper describes results from the GALAXY arm of the ongoing CIRCULATE-Japan trial, which is one of the largest and most comprehensive prospective studies of MRD testing in resectable CRC. The data builds on results previously presented at the 2022 ASCO Gastrointestinal Cancers Symposium (ASCO GI), now with median clinical follow-up extended to 16.74 months and DFS assessment at 18 months.
In the study, 1,039 patients with stage II-IV resectable CRC were monitored prospectively using the Signatera MRD test. Key takeaways include:
“Until now, oncologists did not have adequate tools to determine which colorectal cancer patients are likely to benefit from adjuvant systemic therapy,” said the study’s principal investigator, Dr. Takayuki Yoshino, of the National Cancer Center Hospital East, Kashiwa, Chiba, Japan. “This study provides strong evidence that Signatera MRD-positive patients will benefit significantly from adjuvant therapy, while MRD-negative patients may be safely observed, regardless of clinical or pathological stage.”
“This is a practice-changing study for the colorectal cancer community, demonstrating the predictive power of Signatera in the adjuvant setting,” said Minetta Liu, M.D., chief medical officer of oncology at Natera. “We are proud to partner with the CIRCULATE consortium and look forward to making Signatera accessible to all colorectal cancer patients in the U.S., Japan and worldwide.”
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. Signatera is intended to detect and quantify cancer left in the body, at levels down to a single tumor molecule in a tube of blood, to identify recurrence earlier and to help optimize treatment decisions.
