SignateraTM Genome Clinical Performance Highlighted at ASCO 2025
Overall pan-cancer sensitivity of 94% and specificity of 100%, with analytical detection down to 1 PPM AUSTIN, Texas, June 02, 2025--(BUSINESS WIRE)--Natera, Inc. (NASDAQ: NTRA), a global leader in cell-free DNA and precision medicine, announced results from a large-scale pan-cancer study of its Signatera Genome assay, which was presented today, June 2nd, at the 2025 American Society of Clinical Oncology (ASCO) Annual Meeting. The study analyzed the performance of Signatera Genome in a cohort of 392 patients (> 2,600 plasma samples) across five different tumor types (breast cancer, non-small cell lung cancer, melanoma, renal cell carcinoma, and colorectal cancer). Key results included: Excellent pan-cancer performance: Signatera Genome demonstrated overall longitudinal sensitivity of 94% and specificity of 100% across 5 cancer types. Longitudinal sensitivity was 100% in lung cancer and renal cancer, and post-surgical landmark sensitivity was over 70% in both lung cancer and breast cancer. Ultrasensitive detection: In the surveillance setting, nearly 50% of Signatera-positive cases were detected in the ultra-sensitive range (≤100 parts per million). Highly predictive of long-term outcomes: In the pancancer cohort, patients who tested Signatera-negative had excellent prognosis, with 100% distant relapse-free survival (DRFS) at 12 months and 99% at 24 months. In contrast, Signatera-positive patients faced a markedly higher risk of recurrence, with DRFS dropping to 41% at 12 months and just 14% at 24 months. Extended lead times: Signatera Genome detected recurrence 3 months earlier, on average, compared to the Signatera Exome assay. Demonstrates Signatera's potential to identify which patients may benefit from adjuvant therapy: Among Signatera-positive patients, those who received adjuvant therapy had significantly improved outcomes, with a 12-month DRFS of 83% compared to 49% for those who did not receive therapy. For Signatera-negative patients, there was no meaningful benefit from adjuvant therapy with a 12-month DRFS of 93% (treated) vs. 98% (observation). "These results highlight that our ultra-sensitive Signatera Genome assay not only enables detection of ctDNA at extremely low levels, but also provides powerful insights into patient prognosis and treatment response," said Alexey Aleshin, M.D., MBA, corporate chief medical officer and general manager of oncology at Natera. "This is one of the largest MRD studies of a genome tumor-informed MRD assay, and reinforces the excellent performance of Signatera across a wide range of solid tumors."

Natera to Present over 25 Signatera™ Studies at 2025 ASCO Annual Meeting
Studies include nearly 25,000 patients across multiple indications, showcasing the clinical impact of Signatera Breast: 8 accepted abstracts (4 oral presentations), including interim analysis from the randomized Signatera-guided interventional DARE trial; a large real-world study of metastatic treatment monitoring; and two readouts from the ISPY-2 trial Signatera Genome: Large-scale, pan-cancer performance of Signatera Genome assay GI, GU, Skin, Sarcoma: Significance of Signatera MRD and dynamics to predict recurrence, progression, and treatment response across multiple disease subtypes AUSTIN, Texas, May 22, 2025--(BUSINESS WIRE)--Natera, Inc. (NASDAQ: NTRA), a global leader in cell-free DNA and precision medicine, today announced that data from more than 25 Signatera studies will be presented at the 2025 American Society of Clinical Oncology (ASCO) Annual Meeting, taking place from May 30 - June 3, 2025 in Chicago, IL. Together with its collaborators, Natera will showcase the clinical utility of Signatera across 10 different cancer types. This extraordinary breadth of data includes analyses of thousands of patients, demonstrating Natera's leadership in circulating tumor DNA (ctDNA) monitoring and molecular residual disease (MRD) assessment. "The depth and breadth of Natera's research at ASCO is our most significant to date, with multiple impactful datasets in several histologies," said Alexey Aleshin, M.D., corporate chief medical officer and general manager of oncology at Natera. "The interim analysis from the DARE trial shows a possible first signal in a randomized setting that treating high-risk breast cancer patients based on Signatera results can impact clearance rates. We also look forward to sharing results on our ultra-sensitive Signatera Genome assay, along with numerous other presentations underscoring our commitment to advance the way cancer is managed." Highlights include: DARE Clinical Trial: Oral Presentation DARE is a prospective, randomized study, launched in 2021, to investigate the utility of Signatera for guiding adjuvant endocrine therapy in 585 women with high-risk, estrogen receptor-positive, HER2-negative (ER+/HER2-) breast cancer. It assesses the novel concept of "treatment on molecular recurrence" (TOMR). Patients who were Signatera-positive and imaging-negative were randomized into two arms: the standard-of-care (SOC) arm with endocrine therapy vs. the escalated arm with fulvestrant+palbociclib (CDK 4/6i). This interim analysis of 507 women and 2,208 plasma samples demonstrates the exceptional clinical performance of Signatera, and the early feasibility of both this treatment escalation approach and the TOMR trial strategy, including: Strong test sensitivity and NPV: Among patients who remained persistently Signatera-negative during screening (>400 pts), 99% remained recurrence free with a median follow up of 27.4 months. High randomization rate: Of patients who tested Signatera-positive, 73% were negative on imaging, and 93% were willing to be randomized. 2x higher ctDNA clearance: Patients in Arm A had a 2x higher rate of ctDNA clearance at 3 months vs. Arm B. Signatera Monitoring in Metastatic Breast Cancer: Oral Presentation This real-world analysis of over 600 metastatic breast cancer (mBC) patients across all disease subtypes and a wide range of therapeutic regimens (e.g., chemo, ADCs, CDK4/6) shows the utility of metastatic monitoring with Signatera: Serial ctDNA testing done at an appropriate cadence (6 weeks) can inform treatment response and clinical decisions in metastatic breast cancer. Signatera ctDNA dynamics were the strongest predictor of treatment benefit in a multivariate analysis, based on measuring time to next treatment (TTNT). Nearly 75% of patients with favorable dynamics remained on the same treatment for over 4 months, including those receiving antibody drug conjugates (ADCs) where therapy response can be challenging to evaluate on imaging. Pan-Cancer Performance of Signatera Genome: Poster Presentation Large-scale presentation of Signatera's Genome assay, analyzing more than 3,000 samples from over 300 patients across 5 major cancer types. The study includes analysis of patients with breast cancer, colorectal cancer, non-small cell lung cancer, melanoma, and renal cell carcinoma. Signatera Performance in Post-Surgical Stage I-IIIb Melanoma: Poster Presentation This study includes 197 patients and 1,681 plasma samples, tested for a median period of 2 years. This is one of the most comprehensive MRD/monitoring datasets thus far in early melanoma, demonstrating the ability of Signatera to identify patients who may benefit from escalated imaging or earlier treatment initiation. Post-surgical Signatera-positivity was the most significant predictor of recurrence free survival (RFS). In the surveillance setting, Signatera-positivity was predictive of shorter RFS (HR: 24.0, P < 0.001).

Largest Sarcoma Study to Date with ctDNA Analysis Demonstrates Excellent Performance for Signatera
Stanford-led study included over 2,100 Signatera samples from over 200 sarcoma patients, with overall sensitivity of 89% and specificity of 100% Leiomyosarcoma, the most common subtype in the cohort, demonstrated sensitivity of 93% and specificity of 100% AUSTIN, Texas, May 05, 2025--(BUSINESS WIRE)--Natera, Inc. (NASDAQ: NTRA), a global leader in cell-free DNA and precision medicine, today announced the results of a study led by Stanford University School of Medicine for the evaluation of Signatera, Natera's personalized molecular residual disease (MRD) test, in patients with soft tissue and bone sarcomas. Results of the study (Utilizing Circulating Tumor DNA to Monitor Sarcoma Treatment and Recurrence) were presented at the 2025 Society of Surgical Oncology (SSO) Annual Meeting in March. With evaluation of approximately 200 patients and more than 2,100 plasma samples across multiple distinct subtypes, this is the largest sarcoma cohort to date using personalized circulating-tumor DNA (ctDNA) monitoring. The study assessed the correlation of Signatera results with imaging, stratified by sarcoma subtype, and followed patients through treatment, disease progression, and surveillance. Key findings included: The results demonstrated excellent test performance, with overall sensitivity to recurrence of 89% and specificity of 100%. In leiomyosarcoma, the most common subtype in the cohort, sensitivity was 93%, with specificity of 100%. For leiomyosarcoma patients who experienced progression, ctDNA kinetics during subsequent therapy were highly correlated with treatment response (90%). Sarcomas are a heterogeneous group of rare cancers, with more than 70 distinct histologic subtypes1, making treatment response and recurrence especially difficult to monitor through standard imaging and clinical evaluation. There are approximately 17,000 new cases of sarcoma diagnosed annually in the United States.2 "This data represents a major step forward in understanding how ctDNA monitoring can be applied across a diverse range of sarcoma subtypes," said Beatrice J. Sun, M.D., department of surgery at Stanford University. "With the ability to noninvasively detect disease recurrence and monitor treatment response, Signatera demonstrates the potential to meaningfully improve personalized care for patients with sarcoma." "This is the most comprehensive dataset to date on ctDNA monitoring in sarcoma, and it shows excellent performance of Signatera in a difficult-to-monitor cancer," said Alexey Aleshin, M.D., corporate chief medical officer and general manager of oncology at Natera. "The heterogeneity of sarcoma demands a personalized approach, and these results support Signatera's unique ability to track disease status with precision across a broad spectrum of subtypes." This retrospective real-world study demonstrates the promise of Signatera as a tool to monitor disease recurrence and treatment response. To build on these findings, the team intends to launch a prospective study to further demonstrate Signatera's clinical utility and explore its role in informing treatment decisions and improving future sarcoma care.
