Personalized MRD Testing
Signatera™ is redefining the standard for MRD assessment through personalized, tumor-informed molecular testing.
By custom-designing each assay to a patient's unique cancer signature, Signatera™ identifies colorectal cancer recurrence with high sensitivity, detecting molecular relapse months ahead of traditional imaging. This window of lead time empowers clinicians to intervene earlier, optimize adjuvant therapy, and make more confident treatment decisions.
MRD Assessment
Signatera™ identifies colorectal cancer recurrence with high sensitivity by tracking patient-specific tumor variants over time.
That molecular view can support treatment planning across early and late stage CRC, helping care teams interpret recurrence risk, therapy response, and surveillance signals with greater confidence.
Inform Clinical Challenges
Signatera™ MRD status can provide clinically meaningful insight into survival and recurrence risk.
of ctDNA-negative patients vs. 71.8% of ctDNA-positive patients had 36-month OS.1
ctDNA-positive patients who achieved sustained clearance had 100% OS at 24 months.1
Treatment Escalation
CALGB (Alliance)/SWOG 80702 publication JAMA Oncology evaluated the predictive and prognostic value of Signatera™ in 940 stage III colon cancer treated with adjuvant FOLFOX ± celecoxib.
Signatera™-positive patients treated with both chemotherapy and celecoxib showed a 40% improvement in overall survival compared to chemotherapy alone.2
No benefit from celecoxib was observed in Signatera™-negative patients.
Celecoxib improved DFS in Signatera™-positive patients, independent of PIK3CA mutational status.
Natera Cancer Care
Altera™ tumor genomic profiling for patient selection + Signatera™ MRD testing. Altera™ detects PI3K pathway mutations (PIK3CA, PTEN, PIK3R1), which guide NSAID therapy decisions.
With a single sample, you can get molecular residual disease (MRD) and tumor genomic profiling from the same tumor sample, enabling selection of the right patients for additional therapy and tracking MRD status over time.
Metastasis-Directed Therapy
Signatera™ identified more patients eligible for curative-intent MDT during surveillance by detecting recurrence at the molecular level, when patients are still candidates for local therapy.3
Clinical Applications
Medically actionable information can guide treatment decisions from diagnosis through survivorship.
Monitor neoadjuvant response with serial Signatera™ testing. Identify low-risk patients who are ctDNA-negative to potentially support a nonsurgical watch and wait approach.
Identify patients at high risk of recurrence who may benefit from adjuvant chemotherapy.
Assess MRD more accurately than current risk assessment methods. ctDNA-positivity in the surveillance window was predictive of inferior DFS.
Serial Testing
Compared to patients who were serially ctDNA-negative, patients with ctDNA positivity at any timepoint were approximately 34 times more likely to recur (HR: 33.56, 95% CI: 26.07-43.20, P < 0.0001).1
Serial monitoring can help clinicians evaluate neoadjuvant response, post-surgical MRD status, and recurrence risk across the patient journey.
