New AI-derived model integrates longitudinal ctDNA and clinical data with digital pathology and tumor sequencing data, to refine recurrence risk assessment and outcomes prediction

Natera, Inc. (NASDAQ: NTRA), a global leader in cell-free DNA (cfDNA) testing and precision medicine, today announced an advancement in molecular residual disease (MRD)-based risk stratification that is expected to extend the company’s leadership in oncology. The new multi-modal model will integrate longitudinal ctDNA and clinical data with digital pathology imaging and tumor sequencing data, to enhance the Signatera™ MRD assessment.

Signatera has transformed cancer management by enabling ultra-sensitive MRD detection and informing more personalized treatment decisions. The multi-modal approach leverages additional information from the patient’s tumor sample, using Natera’s AI models trained on long-term molecular and clinical outcomes from Natera’s proprietary database of approximately 300,000 patients tested with Signatera since launch. The approach shows statistically and clinically significant enhancements, with data expected to be presented at an upcoming conference ahead of launches in the research and clinical settings.

“MRD testing has become a critical tool in precision oncology, and the next phase of innovation is understanding how molecular signals can further refine the trajectory for every patient,” said Alexey Aleshin, M.D., corporate chief medical officer and general manager of oncology. “Predicting these longitudinal patterns with AI models depends on access to large datasets built over years of real-world clinical use, where repeated ctDNA measurements are linked to pathology, treatment decisions and outcomes. Natera is uniquely positioned to do this and improve oncology patient care.”

The innovation to enhance MRD diagnostics is part of Natera’s active research and development pipeline and builds on its previously announced AI initiatives, including its proprietary AI foundation model trained on longitudinal ctDNA data, AI-driven neoantigen prediction and predictive modeling of immuno-oncology treatment response. The company continues to invest in expanding its AI capabilities and strategic collaborations, including recently announced initiatives with NVIDIA, to support scalable, high-performance modeling of complex biological data.
