Caris Assure is a blood-based molecular profiling assay that uses a novel circulating nucleic acids sequencing (cNAS) approach to analyze the Whole Exome (cfDNA) and Whole Transcriptome (cfRNA) of 22,000 genes, including Loss of Heterozygosity (LOH), Microsatellite Instability (MSI) and Tumor Mutational Burden (TMB) from a simple blood sample. This unique assay includes characterization of somatic tumor alterations, somatic Clonal Hematopoiesis of Indeterminate Potential (CHIP) alterations and identification of incidental germline findings. The assay further enables minimally invasive serial monitoring for detection of tumor heterogeneity and emergence of resistance mutations.
