Texas - Natera, Inc. (NASDAQ: NTRA), a global leader in cell-free DNA testing, today announced a new study published in The Journal of Thoracic and Cardiovascular Surgery demonstrating the ability of Natera's personalized and tumor-informed molecular residual disease (MRD) test, Signatera, to risk stratify and detect recurrence early in patients with resected stage I-II non-small cell lung cancer (NSCLC).
Worldwide, lung cancer is the second most commonly diagnosed cancer. In the U.S., NSCLC accounts for 81% of all lung cancer diagnoses.1 About 25-30% of NSCLC patients are diagnosed with stage I-II disease.2,3 These patients typically undergo curative-intent complete surgical resection and may be treated with adjuvant systemic therapy. However, 30-55% of patients develop disease recurrence within the first five years after surgery, and five-year overall survival ranges from 68-92% for stage I and 53-60% for stage II NSCLC patients respectively.4,5,6
Given the significant risk of recurrence and death in NSCLC, it is critical to accurately risk-stratify patients to identify who may derive benefit from additional treatment after surgery. In addition, there is a need for sensitive and specific biomarkers to support early detection of recurrence before the onset of disease-related symptoms at a time when therapy might provide greater clinical benefit.
This study investigated the association of circulating tumor DNA (ctDNA) status with recurrence-free survival (RFS), as well as changes in clinical practice after a positive ctDNA result in patients with resected stage I-II NSCLC. A total of 378 serial plasma samples from 108 NSCLC patients were analyzed after surgical resection, with a median clinical followup of 16 months.
Key findings include: Patients who were ctDNA-positive within 6 months post-resection and prior to adjuvant treatment were 53-times more likely to recur (p
Natera, Inc. is a diagnostics company, which is focused on the development and commercialization of molecular testing services, applying its technology in the fields of womenâs health, oncology and organ health. Its cell-free deoxyribonucleic acid (cfDNA) technology combines its molecular assays, which reliably measure many informative regions across the genome from samples as small as a single cell. The Company's product offerings include Panorama Non-Invasive Prenatal Test (NIPT), Vistara, Horizon Carrier Screening, Spectrum Preimplantation Genetics, Anora Miscarriage Test, Empower, and Prospera. The Company also offers Constellation, a cloud-based software platform that enables laboratory customers to gain access through the cloud to the Companyâs algorithms and bioinformatics in order to validate and launch tests based on the Companyâs technology. Its NIPT screens for chromosomal abnormalities of a fetus as well as in twin pregnancies, typically with a blood draw from the mother.
