Signatera

Transforming the management of cancer with personalized testing

Signatera is a highly sensitive and personalized molecular residual disease assay (MRD) using circulating tumor DNA (ctDNA), custom designed for each patient to help identify relapse earlier than standard of care tools.

Why circulating tumor DNA (ctDNA) for MRD assessment?

  • Cancer cells release circulating tumor DNA (ctDNA) into the bloodstream
  • ctDNA is a powerful tool that can be measured to assess the absence or presence of molecular residual disease (MRD)
  • Dynamic real-time biomarker: the normal half-life is less than an hour

Clinical applications of ctDNA testing for MRD assessment

Now it is possible to detect cancer recurrence earlier than before

“Tumor-informed circulating tumor DNA tests have broad clinical utility across cancer types. I am excited to partner with Natera to further explore early indications of treatment response, or lack thereof, using this novel technology.”

Signatera helps you dive deeper

Detect residual disease early. Treat with confidence.

Adjuvant setting

  • Use Signatera after surgery to evaluate the need for adjuvant chemotherapy
  • Personalize and help inform when to reduce treatment
Surveillance setting

  • Assess for MRD more accurately than current risk-assessment methods
  • Use Signatera alongside CEA to detect recurrence earlier while it may still be resectable, or to reduce false positive CEA results

Signatera is the first tumor-specific assay for truly individualized cancer care

Personalized design for every patient

  • Custom-built assay—based on the unique mutation signature of each patient’s tumor—identifies and tracks tumor mutations at the source
  • Once a personalized assay is designed, a patient’s blood can be used to accurately monitor for the presence or absence of the disease over time

A positive Signatera result predicts relapse with overall positive predictive value more than 98%1-4

In clinical studies, Signatera showed high performance across multiple solid tumors

MRD testing uniquely personalized to each patient’s tumor mutation signature

  • Highly sensitive non-invasive assay to detect MRD earlier than other standard of care clinical tools.1‑4
  • Earlier cancer recurrence monitoring to help inform adjuvant treatment decisions.
  • Custom-built for each patient, using tumor tissue from surgical resection.
  • Highest level of monitoring accuracy when determining whether to augment or reduce therapy.

How Signatera Works: a personalized and tumor informed approach to MRD surveillance

ONC_how it works_MD-01

Personalized, tumor-informed assay

One-time, primary tissue sample and matched normal tissue is required for whole exome sequencing and personalized test design.

ONC_how it works_MD-02

Ultrasensitive ctDNA detection

Signatera is designed to detect ctDNA of somatic and truncal variants to optimize sensitivity. Tumor-informed method enables filtering of CHIP mutations to decrease false positive rates.

ONC_how it works_MD-03

Optimized for longitudinal monitoring

Once the patient’s personalized test has been designed, only a blood sample is needed each subsequent time Signatera is ordered for the adjuvant program or surveillance program.

How to order

To get started, send in your Signatera requisition form, sign in to the online portal or talk to your sales representative.

Natera accepts all commercial and public insurances (Medicare, Medicaid)

We are committed to make testing as affordable as possible

Medicare Coverage

  • For monitoring disease progression, recurrence, or relapse for colorectal cancer (CRC) and muscle invasive bladder cancer (MIBC), in both the adjuvant and surveillance settings.
  • Monitoring of response to immune-checkpoint inhibitor therapy for any solid tumor.


Commercial Insurance

We welcome all insurance plans.

We will work with patients so that cost is not a barrier for testing.

We offer an affordable self-pay rate for those patients who do not wish to use insurance.
