Natera Announces Updated Signatera™ MRD Data from CIRCULATE-Japan Presented in Plenary Talk at the Society of Surgical Oncology Conference, and Activation of CIRCULATE-US Trial
Natera announced new data from the CIRCULATE-Japan trial, revealing a 75% detection rate of colorectal cancer recurrence from a single blood draw four weeks post-surgery. This update, presented at the SSO 2022 conference, indicates improved outcomes for patients identified through Natera's Signatera test. The CIRCULATE-Japan study is the largest clinical trial focusing on molecular residual disease in colorectal cancer, enrolling over 3,300 patients to date. Additionally, Natera activated the CIRCULATE-US trial to further explore MRD-guided treatment strategies.
- 75% detection rate of recurrence in stage II-III patients with Signatera at 4 weeks post-surgery.
- Increased adoption of Signatera among cancer surgeons for decision-making.
- Activation of the CIRCULATE-US trial, expanding research on MRD-guided treatment.
- None.

AUSTIN, Texas, March 21, 2022 /PRNewswire/ -- Natera, Inc. (NASDAQ: NTRA), a global leader in cell-free DNA testing, today announced new Signatera data from the prospective, multi-center CIRCULATE-Japan trial, presented by Dr. Eiji Oki of Kyushu University in an oral presentation at the Society of Surgical Oncology (SSO) 2022 International Conference on Surgical Cancer Care.
CIRCULATE-Japan is the largest molecular residual disease (MRD)-guided clinical trial with more than 3,300 stage I-IV colorectal cancer (CRC) patients enrolled to date. This interim analysis at SSO, similar to the one previously presented at the 2022 ASCO GI symposium, analyzed 6-month and 12-month outcomes from 1,040 patients and showed that Signatera MRD-positive patients benefited significantly from adjuvant chemotherapy (ACT), while Signatera MRD-negative patients did not benefit from ACT.
Latest findings exclusive to SSO 2022 demonstrate
"Learnings from our study consistently suggest that stratifying post-surgical treatment decisions using Signatera can identify patients likely to benefit from adjuvant chemotherapy across stages," said the study's Principal Investigator, Dr. Takayuki Yoshino, of the National Cancer Center Hospital East, Kashiwa, Chiba, Japan. "We look forward to continuing to expand the study."
The presentation at SSO also indicates increasing interest in and adoption of Signatera among cancer surgeons, who are finding utility in personalized monitoring and MRD assessment to inform surgical decisions. Signatera has been shown in several studies3,4 to be predictive of treatment response in the neoadjuvant setting (before surgery) as well as the adjuvant setting (after surgery), across multiple cancer types.
In addition to presenting the latest CIRCULATE-Japan study data, Natera also announced the activation of the CIRCULATE-US trial, a national, prospective, multi-center, randomized clinical trial to investigate MRD-guided treatment strategies for patients with early-stage CRC. The study, which is being conducted in partnership with NRG Oncology and funded by the National Cancer Institute (NCI), was recently granted an investigational device exemption (IDE) from the FDA after a thorough review of Natera's clinical and analytical validation data.
"Natera is dedicated to continuing to drive improvement in MRD test sensitivity and improving CRC patient outcomes by executing definitive, practice-changing prospective studies," said Dr. Adham Jurdi, medical director of oncology at Natera. "We're delighted to be at the forefront of MRD and colorectal cancer research and excited to see these landmark studies, like CIRCULATE-US, progress."
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.
