Natera announced that the Expand clinical trial has enrolled over 2,000 patients, more than doubling enrollment in the last 12 months. Expand is a prospective, blinded, multi-site clinical trial designed to study Natera's Fetal Focus single-gene noninvasive prenatal test. The trial was featured in an oral plenary session at the Society for Maternal-Fetal Medicine Expand Meeting in February 2026. "In developing Fetal Focus, our goal has been to expand the scope of what noninvasive prenatal testing can deliver," said Sheetal Parmar, SVP of Medical Affairs, Women's Health at Natera. "With more than 2,000 patients enrolled, EXPAND is helping to set a new standard for clinical evidence in single-gene NIPT, and we remain focused on generating high-quality data to support clinicians and the families they serve."

About NTRA
Natera, Inc. provides cell-free DNA (cfDNA) and genetic testing, dedicated to oncology, women’s health, and organ health. The Company's cfDNA technology platform combines novel molecular biology techniques with bioinformatics software and artificial intelligence. It has leveraged its platform to develop non-invasive prenatal test on the market (Panorama), the first tumor-specific assay for truly individualized cancer care (Signatera), best-in-class rejection assessment for kidney transplantation (Prospera) and others. In the women’s health space, it develops and commercializes non- or minimally- invasive tests to evaluate risk for, and thereby enable early detection of, a range of genetic conditions, such as Down syndrome. In oncology, it is focused on detecting molecular residual disease and recurrence monitoring in solid tumors, among others. In organ health, it offers tests to assess kidney, heart, and lung transplant rejection as well as genetic testing for chronic kidney disease.

Natera Partners with Diakonos to Evaluate New Therapy
- Collaboration Background: Natera has partnered with Diakonos Oncology Corp. to utilize Signatera™ for assessing molecular responses in patients with refractory melanoma enrolled in the DOC-RM clinical trial, marking a significant advancement in precision medicine for cancer treatment.
- Clinical Trial Progress: The DOC-RM trial, which began enrollment in May, evaluates the FDA Fast Track-designated DOC1021 therapy, aiming to provide new treatment options for patients with unresectable or metastatic cutaneous melanoma, indicating potential positive impacts on patient outcomes.
- Technical Advantage: By analyzing circulating tumor DNA (ctDNA) at multiple timepoints, Natera's Signatera test can offer earlier insights into molecular responses compared to traditional imaging, enabling physicians to better understand treatment dynamics and optimize therapeutic strategies.
- Market Demand: Patients with refractory melanoma face significant unmet medical needs, and the collaboration between Natera and Diakonos not only aims to address this gap but also has the potential to drive the development of new therapies, enhancing patient survival rates and quality of life.

Natera Initiates SIGNAL-ER 101 Study for Early-Stage Breast Cancer
- Study Launch: Natera Inc. has enrolled its first patient in the SIGNAL-ER 101 study, aimed at facilitating diagnosis and treatment for early-stage breast cancer through the Signatera MRD test, marking a significant advancement in precision medicine.
- Patient Recruitment Plan: The study plans to enroll 725 intermediate-risk HR+/HER- early-stage breast cancer patients, allowing those diagnosed as MRD negative via the Signatera test to receive endocrine therapy alone, thus avoiding unnecessary CDK4/6 inhibitor treatment.
- Efficacy Improvement: Endocrine therapy shows a 95% recurrence-free success rate in MRD negative patients, highlighting the importance of the Signatera test in optimizing treatment regimens and potentially improving patient outcomes significantly.
- Market Reaction: Natera's stock is currently trading at $205.52, up 1.19%, reflecting positive market sentiment regarding the progress of its new study, which may drive further investment and development in the precision medicine sector.

Natera Launches SIGNAL-ER 101 Trial for Breast Cancer Treatment De-escalation
- SIGNAL-ER 101 Trial Launch: Natera has initiated the SIGNAL-ER 101 trial to evaluate the clinical utility of Signatera MRD-guided de-escalation strategies in early-stage HR+/HER2- breast cancer, aiming to enroll 725 patients across 50 sites in the U.S.
- Standard of Care Transformation: The current standard recommends 2-3 years of CDK4/6 inhibitors for intermediate-risk HR+/HER2- breast cancer patients, yet only about 3% benefit, with over 60% experiencing serious adverse events, indicating a critical need to reassess treatment necessity and efficacy.
- Potential of MRD-Negative Patients: Data shows that MRD-negative patients tested with Signatera have over 95% distant recurrence-free interval at 5 years, suggesting they can safely defer CDK4/6 inhibition, thereby reducing unnecessary treatments and associated side effects.
- Optimizing Treatment Strategies: The implementation of SIGNAL-ER 101 not only helps mitigate overtreatment in breast cancer patients but also provides crucial evidence for Natera's innovations in cancer treatment, supporting MRD-based personalized treatment optimization and enhancing patient quality of life.

Natera Enhances Panorama NIPT with Low Fetal Fraction Technology
- Technological Innovation: Natera's Panorama non-invasive prenatal test (NIPT) has successfully reduced the no-call rate to 0.5% for low fetal fraction samples through SNP-informed deep sequencing technology, significantly enhancing the accuracy and reliability of testing, thereby enabling more patients to receive actionable results.
- Clinical Validation: In a prospective clinical validation study involving 3,323 high- and low-risk pregnant patients, Panorama demonstrated 100% sensitivity for trisomy 21 and 93.3% sensitivity for trisomy 18 in low fetal fraction samples, indicating a substantial improvement in its competitive edge in this critical area.
- Market Demand Fulfillment: Low fetal fraction has remained a significant challenge in non-invasive prenatal screening, and Natera's application of this new technology not only addresses this issue but also fills the gap in the market regarding performance data for low fetal fraction testing, thereby enhancing its market competitiveness.
- Strategic Implications: This technological upgrade not only improves Panorama's clinical performance but also simplifies processes for healthcare providers by delivering more reliable testing results, positioning the company favorably in the rapidly evolving prenatal testing market.
