The Most Powerful
Liquid Biopsy Assay
Ever Developed

Caris AssureTM

Caris Assure is a minimally invasive blood test that provides comprehensive molecular analysis of tumor biomarkers when tumor tissue is not available. The assay utilizes circulating Nucleic Acid Sequencing (cNAS), a novel approach to liquid biopsy that analyzes cell-free DNA and RNA from plasma, plus genomic DNA and messenger RNA from circulating white blood cells (WBCs), to distinguish:
  • Somatic tumor variants – Caris Assure provides confidence in therapy decisions by distinguishing somatic tumor from CHIP or germline variants, helping to avoid off-target drugs.
  • Incidental CHIP – By sequencing both plasma and buffy coat (i.e., white blood cells), Caris Assure distinguishes clonal hematopoiesis of indeterminate potential (CHIP) from somatic tumor mutations.
  • Incidental germline† – Also by sequencing plasma and buffy coat, Caris Assure can distinguish germline and somatic mutations.
Caris Assure has the potential to pick up more mutations, with a sensitivity of 93.8% when compared to matched tissue collected within 30 days and using ≥5 ng of input material. Test results include genomic signatures such as microsatellite instability (MSI) and blood tumor mutational burden (bTMB), plus HLA genotyping to provide deep molecular insights to help inform therapy decisions.

†Not a replacement for comprehensive germline testing. Incidental pathogenic alterations detected in ACMG recognized cancer genes are reported. Negative results do not imply the patient does not harbor a germline mutation.

Caris Assure™ is intended for patients with previously diagnosed solid malignant neoplasms when tissue is not feasible and is to be used by qualified healthcare professionals. RNA results are intended for investigational purposes only. Not available in all locations.

Clinical Confidence Through Comprehensive and Reliable Results

This revolutionary, pan-cancer assay utilizes a novel circulating Nucleic Acid Sequencing (cNAS) approach. With deep molecular insights from a minimally invasive blood sample, Caris Assure delivers uncompromising reliability and performance to guide personalized treatment decisions and help improve patient outcomes.

Somatic Tumor

By distinguishing somatic (acquired) variants from incidental CHIP or incidental germline results, Caris Assure provides confidence in therapy decisions and avoidance of off-target drugs.

Incidental CHIP

Clonal hematopoiesis of indeterminate potential (CHIP) mutations from aging white blood cells may cause false positive results in blood-based assays. Caris Assure distinguishes CHIP from somatic tumor mutations to improve accuracy.

Incidental Germline

Caris Assure analyzes genomic DNA from circulating white blood cells found in the buffy coat and can distinguish incidental germline† mutations from somatic mutations.
