Biopharma & Research Solutions

Build early evidence of therapy efficacy, enroll patients most likely to benefit from treatment, and leverage data-driven trial designs to accelerate your drug development1-5.

Assess Disease at the Molecular Level

Signatera™ is a personalized, tumor-informed circulating tumor DNA (ctDNA) assay to detect and monitor molecular residual disease (MRD).

ONC_how it works_MD-01

Whole Exome Sequencing

Sequence tumor tissue and matched normal blood to identify tumor-specific genomic signatures

ONC_how it works_MD-02

Personalized Assay Design

Create custom multiplex PCR assay to target patient-specific clonal mutations in plasma

Longitudinal Monitoring

Assess ctDNA levels over time to evaluate disease persistence, recurrence, and treatment response

Enrich for High Risk Populations

  • Stratify & enrich for study participants most likely to benefit from additional treatment1-2
  • Treat on molecular relapse at time of lower disease burden


  • Maximize therapy efficacy and decrease necessary study size
  • Move ahead of next-line therapies

Predict Response Sooner

  • Predict therapy response as early as 6 weeks3 into treatment
  • Support early therapy efficacy readouts as a co-primary or surrogate endpoint


  • Improve program prioritization and planning
  • Accelerate approval of new therapies

… ctDNA as a biomarker has a number of potential regulatory and clinical uses in the early stage setting that may assist and expedite drug development … to enrich a high- or low-risk population for study in a trial, to reflect a patient’s response to treatment, or potentially as an early marker of efficacy …”
