Clinical Applications

Signatera™ Indications

Signatera™ can be used for a variety of cancer types.

Gastrointestinal Cancer

Signatera™ is custom-built to your unique set of tumor mutations to predict colorectal cancer recurrence. Because it is highly sensitive it can detect very small traces of tumor in the body so the oncologist can know earlier if cancer is present and make more informed decisions regarding the treatment.

Signatera™ is covered by Medicare (U.S.A.) for Stage II-IV and oligometastatic colorectal cancer (CRC) in the adjuvant and recurrence monitoring settings.

Bladder Cancer

Personalized molecular residual disease (MRD) testing in bladder cancer.

Signatera™ is covered by Medicare U.S.A. for muscle invasive bladder cancer (MIBC) in the adjuvant and recurrence monitoring settings.

Lymphoma

Signatera™ can be used to help better manage your patient’s lymphoma with a more personalized approach to their care including assessing MRD status after completion of initial therapy to help predict relapse and identifying patients who are MRD-positive to inform additional treatments.

Understanding MRD

Why circulating tumor DNA (ctDNA) for molecular residual disease assay (MRD) assessment?

ctDNA is a powerful tool that can be measured to assess the absence or presence of MRD.

Signatera™ is a highly sensitive and personalized MRD assay using ctDNA and is custom designed for each patient to help identify relapse earlier than standard of care tools.

Validated Performance

A positive Signatera™ result predicts relapse with overall positive predictive value more than 98%1-8

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

Truly Individualized

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.

How It Works

A personalized and tumor-informed approach to MRD surveillance

01

Personalized, tumor-informed assay

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

02

Optimized for longitudinal monitoring

Once the patient’s personalized test has been designed, only a blood sample is needed each subsequent time.

03

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.

Coverage

Covered by Medicare U.S.A. for multiple solid tumor indications

Medicare coverage indications for colorectal, breast, bladder, lung, ovarian, and solid tumors

Questions, Answered

FAQ

What is Signatera™ and what does it test for?

Signatera™ is a personalized, tumor-informed assay optimized to detect circulating tumor DNA (ctDNA) for molecular residual disease (MRD) assessment, treatment response monitoring, and early recurrence monitoring.

How is Signatera™ different from current biomarker tests?

Unlike other ctDNA assays, Signatera™ is designed to accurately detect MRD (i.e., not designed for early cancer screening nor for identifying actionable mutations for therapy selection). Instead, Signatera™ is customized for each patient’s unique tumor signature to optimize sensitivity and specificity for accurate MRD assessment.

How accurate is Signatera™?

By only tracking tumor-specific variants, sensitivity is maximized with a low limit of detection (LOD) of 0.01% variant allele frequency (VAF). Also, Signatera™ filters out clonal hematopoiesis of indeterminate potential (CHIP) mutations to greatly reduce false-positive results.

What information does the test report provide?

Signatera™ reports the presence or absence of circulating tumor DNA (ctDNA) and ctDNA quantity in terms of mean tumor molecules per mL (MTM/mL) to allow for assessment of tumor burden over time.

What does a positive Signatera™ result mean?

A positive test result indicates the presence of molecular residual disease (MRD). Serial sampling can be used to track whether disease burden is increasing or decreasing in response to treatment.

What does a negative Signatera™ result mean?

A negative result indicates that molecular residual disease (MRD) was not detected. Serial sampling can be used to track whether disease burden remains undetectable or increases to catch relapse early.

What type of samples are needed for Signatera™?

For initial testing, tumor tissue will need to be provided as a formalin-fixed paraffin-embedded (FFPE) block or on slides. The first blood draw will require one 6 ml EDTA tube and two 10 mL Streck tubes. All subsequent draws will only require two 10 mL Streck tubes.

What is the turnaround time for my Signatera™ results?

Initial test design takes 5-6 weeks after receipt of tumor and blood samples. Subsequent blood draws have a turnaround time of 15 days.
