AUSTIN, Texas, May 31, 2022 /PRNewswire/ -- Natera, Inc. (NASDAQ: NTRA), a global leader in cell-free DNA testing, today announced that new data on its personalized and tumor-informed molecular residual disease (MRD) test, Signatera, will be presented at the 2022 ASCO® Annual Meeting taking place June 3 – 7, 2022.
There will be seven poster presentations and one oral presentation highlighting the prognostic and predictive value of its personalized MRD technology in a wide range of tumors. These data further support Signatera as an effective tool for MRD detection and treatment response monitoring. “These data reinforce the significant potential of ctDNA monitoring to improve outcomes for patients with breast cancer and other solid tumors,” said Charles Coombes, M.D., professor of medical oncology at the Imperial College London and principal investigator of the EBLIS study. Below are highlights of selected Signatera abstracts, with updated data to be presented at the conference: Abstract ID: 562 | June 6, 2022, 8:00 AM-11:00 AM CDT 188 patients with primary breast cancer of different molecular subtypes were followed post-surgery and adjuvant therapy for up to 12 years as part of the prospective, multi-center EBLIS study. Serial Signatera testing predicted metastatic relapse with a median lead interval of 10 months (range: 0-39 months) and relapse detection of 88% (30/34 patients). Relapse-free and overall survival was significantly poorer in patients who were Signatera positive, regardless of subtype (HR 52.98 and 53.69, respectively). Abstract ID: 8540 | June 6, 2022, 8:00 AM-11:00 AM CDT In this prospective cohort, 17 patients with non-resectable stage I-III NSCLC were monitored before, during and after radiotherapy with or without concurrent systemic therapy and adjuvant durvalumab, for a median of 26 months. ctDNA was detected in 82% (14/17) of patients pre-treatment. 100% (9/9) of cases where clinical recurrence occurred had detectable ctDNA, a median of 5.4 months ahead of radiological relapse. ctDNA status after radiotherapy (single time point) as well as during systemic therapy (longitudinally) was highly predictive of disease recurrence (p=0.007, p<0.0001 respectively). Abstract ID: 4525 | June 4, 2022, 1:15 PM-4:15 PM CDT A 21-patient mRCC cohort was monitored using Signatera before and after the first cycle of sunitinib. ctDNA was detected in 81% (17/21) of patients pre-treatment. Patients whose ctDNA concentrations increased over the course of treatment were significantly more likely to experience disease progression (HR 4.9) compared to those with ctDNA decrease. In addition, ctDNA dynamics during systemic therapy allowed for detection of disease progression a median of 12 months ahead of radiographic imaging. Abstract ID: 9566 | June 6, 2022, 1:15 PM-4:15 PM CDT In this prospective, multicenter study of 125 MCC patients, Signatera detected 100% of all clinically evident MCC cases, and primary tumor diameter was strongly correlated with ctDNA concentration (r=0.81, p<0.001). The estimated risk of recurrence was 57%, within 60 days of a positive Signatera result. In contrast, the risk of recurrence was 0% within 60 days, and 3% between 60 - 90 days, of a negative result, demonstrating the value of Signatera for MCC surveillance. Abstract ID: 11547 | June 5, 2022, 8:00 AM-11:00 AM CDT Ten patients with localized, high-risk STS of different types were monitored longitudinally using Signatera at diagnosis, post surgery and radiotherapy. ctDNA was detected in 70% (7/10) of patients at diagnosis, demonstrating the feasibility of Signatera testing in this heterogeneous group of tumors. Abstract ID: 2510 | June 6, 2022, 1:15 PM- 2:45 PM CDT This study investigates the predictive ability of a tissue RNA-based classifier called VIGex, in combination with ctDNA dynamics using Signatera, in patients treated with pembrolizumab in the INSPIRE trial. A total of 57 patients had both VIGex and ctDNA data. VIGex was predictive of treatment response, independently of PD-L1 and TMB, with predictive performance further improved by the addition of on-treatment ctDNA dynamics. 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. About Natera Natera™ is a global leader in cell-free DNA testing, dedicated to oncology, women’s health, and organ health. We aim to make personalized genetic testing and diagnostics part of the standard of care to protect health, and inform earlier, more targeted interventions that help lead to longer, healthier lives. Natera’s tests are validated by more than 100 peer-reviewed publications that demonstrate high accuracy. Natera operates ISO 13485-certified and CAP-accredited laboratories certified under the Clinical Laboratory Improvement Amendments (CLIA) in Austin, Texas and San Carlos, California.
