Foundation Medicine, Inc., a global, patient-focused precision medicine company, today announced the launch of FoundationOne®MRD, a molecular residual disease (MRD) test.1 This launch follows the completion of Roche’s acquisition of SAGA Diagnostics. FoundationOne MRD is the first-of-its-kind MRD test to combine structural variants and digital PCR, enabling ultra-sensitive MRD detection, with high specificity.2
FoundationOne MRD leverages a differentiated approach designed to deliver highly sensitive and specific MRD detection alongside an accelerated turnaround time for healthcare providers. The personalized tumor fingerprint and initial blood test can be expected within approximately 2 to 3 weeks from the sample receipt, and subsequent blood test results can be anticipated within 1 to 3 days. This new MRD offering is covered by Medicare for cancer recurrence monitoring in early-stage breast cancer across all subtypes, with plans for a global launch.3
“FoundationOne MRD represents the next bold step in our mission to transform cancer care throughout a patient’s experience,” said Dan Malarek, CEO of Foundation Medicine. “FoundationOne MRD offers healthcare providers and patients a powerful solution leveraging a proprietary combination of whole genome sequencing (WGS) and digital PCR to reliably detect and monitor structural variants. With our deep expertise, we will incorporate FoundationOne MRD into our comprehensive portfolio to bring answers to even more people.”
FoundationOne MRD enriches Foundation Medicine’s suite of diagnostics tools, empowering healthcare providers to identify disease recurrence earlier, select the best therapies for patients and monitor treatment response over time.

About FoundationOne®MRD
FoundationOne®MRD is performed by SAGA Diagnostics US, Inc. It is a tissue-informed liquid biopsy assay for the detection of circulating tumor DNA (ctDNA). The test entails whole genome sequencing (WGS) of a patient’s tumor specimen to identify candidate structural variants (SVs). This information is used to generate a customized multiplex digital PCR (dPCR) fingerprint for up to 16 SVs. This patient-specific dPCR assay is then used to detect the present or absence of ctDNA. The assay is a laboratory developed test that was developed, and its performance characteristics determined, by SAGA Diagnostics. FoundationOne MRD has not been cleared or approved by the U.S. Food and Drug Administration.
