Natera announced the publication of new data in JAMA Oncology, evaluating the utility of Signatera, its personalized molecular residual disease test, in patients with resected colorectal liver metastases. The data was also presented as an oral presentation at the 2026 European Society for Medical Oncology Gastrointestinal Congress. The liver is the most common site of distant metastasis in colorectal cancer, and CRLM is a major cause of cancer-related mortality. In patients where curative-intent surgery is possible, the benefit of adjuvant chemotherapy has been a point of debate and uncertainty. MRD status has previously been shown to predict a disease free survival benefit from ACT, but not an overall survival benefit. This is the first dataset in a large cohort to show MRD test prediction of OS from ACT in this population. The JAMA paper included 298 patients from the GALAXY trial, the prospective, observational arm of CIRCULATE-Japan. Outcomes were evaluated according to MRD status and whether patients received ACT, with a median follow-up of 43 months. Key findings included: Signatera identified patients who derive a significant survival benefit from ACT. Among MRD-positive patients who underwent surgery without neoadjuvant chemotherapy, ACT was associated with improved DFS and OS compared to observation. MRD-negative patients had favorable outcomes, with no observed survival benefit from ACT. Post-surgical MRD status was strongly prognostic. MRD positivity 2-10 weeks after surgery was associated with significantly worse DFS and OS, including those who received neoadjuvant chemotherapy before surgery, and those who did not.

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.

Signatera Test Shows Survival Benefits in Colorectal Cancer Patients
- Significant Survival Benefit: Among 298 patients with resected colorectal liver metastases, MRD-positive patients receiving adjuvant chemotherapy had a 48-month overall survival rate of 65.3%, significantly higher than the 32.9% in the observation group, highlighting the importance of the Signatera test in personalized treatment.
- Clear Prognostic Indicator: Post-surgical MRD positivity 2-10 weeks after surgery was strongly associated with worse survival outcomes, with hazard ratios of 4.82 for disease-free survival and 9.43 for overall survival in patients who received neoadjuvant chemotherapy, indicating MRD status as a crucial factor in treatment decisions.
- Broad Clinical Application: This study provides critical survival data for clinicians to identify which patients are most likely to benefit from adjuvant chemotherapy, further advancing the application of Signatera in personalized medicine.
- Robust Research Background: The findings were presented at the 2026 European Society for Medical Oncology Congress, emphasizing Natera's leadership in cell-free DNA and precision medicine, which is expected to drive further growth in the oncology sector.

Natera and Aveta Partner for Phase 3 Clinical Trial of APG-157
- Strategic Partnership Initiated: Natera and Aveta Biomics have formed a strategic partnership to advance the AVTA 30-01 clinical trial, evaluating APG-157's efficacy in patients with locally advanced head and neck squamous cell carcinoma, with an expected enrollment of 826 patients across North America, Europe, Asia-Pacific, and Australia, showcasing a strong collaboration in the oncology field.
- Innovative Therapy Potential: APG-157, as a first-in-class oral immunotherapy, has received FDA Fast Track and Orphan Drug Designations, aiming to provide new treatment options for both immune-cold and immune-hot tumors, potentially transforming the treatment landscape for locally advanced head and neck cancer and improving patient survival rates.
- Molecular Testing Application: The AVTA 30-01 trial will incorporate Signatera testing to assess molecular residual disease (MRD) and treatment response, utilizing circulating tumor DNA (ctDNA) technology, which is expected to detect recurrences earlier than conventional imaging, further validating the positive results observed in the Phase 2 trial.
- Significant Market Demand: With a global annual incidence of approximately 950,000 for head and neck cancer, and recurrence remaining a major cause of mortality despite advancements in surgery, radiation, and immunotherapy, the successful development of APG-157 will help address this unmet medical need, enhancing the market positions of both Natera and Aveta.
