Signatera™

Predict Immunotherapy Treatment Benefit As Early As Week 6¹

A personalized tumor-informed circulating tumor DNA assay covered by Medicare for immune checkpoint inhibitor (ICI) treatment response monitoring across all solid tumor types and stages of cancer.

Assess Immunotherapy Treatment Response

Unlike static tumor markers for cancer, the Signatera™ Molecular Residual Disease Test (MRD) quantifies circulating tumor DNA (ctDNA) over time to provide a real-time assessment of changes in disease burden during immunotherapy (IO) treatment.¹

INSPIRE Trial

The INSPIRE trial validated Signatera™ ctDNA testing as an early biomarker of immunotherapy response with 98% baseline ctDNA detection across 94 patients and 25 solid tumor types.¹

Early Changes in ctDNA Levels Predict Treatment Benefit

Changes in ctDNA levels from baseline to week 6 (start of cycle 3) are predictive of immunotherapy benefit across cancer types.¹

ctDNA Clearance at Any Time Correlates with Overall Survival

Overall survival was 100% in patients who experienced ctDNA clearance for at least one on-treatment time point.¹

Review Real-World Case Studies

Is the treatment working?	A patient with stage IV non-small cell lung cancer (NSCLC) who experienced early tumor progression during first-line immunotherapy treatment	Read Case Study
Is the cancer actually progressing?	A patient with stage IV melanoma with an indeterminate imaging result during immunotherapy treatment	Read Case Study
Is the patient an exceptional responder?	A patient with stage IV non-small cell lung cancer (NSCLC) who was able to discontinue immunotherapy treatment after a prolonged, durable, complete response	Read Case Study
