Genes and genomic signatures

Genes and genomic signatures

Comprehensive assessment in a single test

FoundationOne CDx comprehensively examines the tumour genome, assessing the four main classes of genomic alteration in 324 known cancer-relevant genes, while also reporting TMB and MSI, which can help inform eligibility for immunotherapies.1,2,15–23 In addition, FoundationOne CDx reports high Loss of Heterozygosity (LoH), which may reflect if a tumour is homologous recombination deficient (HRD+) and which can help inform the use of poly-ADP ribose polymerase (PARP) inhibitors.24,25

Based on FDA-approved comprehensive platform

FoundationOne CDx is based on our analytically and clinically validated, FDA-approved comprehensive platform.3,4 You can be confident in the insights generated by FoundationOne CDx thanks to the review and approval of the workflow by the FDA, including analytical and clinical validation, and bioinformatics.3,4


In-depth report

EU report includes EU-approved therapies to support clinical decision-making

A clear, in-depth report provides insights on your patient’s genomic profile as well as associated targeted therapies, immunotherapies and relevant clinical trials.5 Approved therapies are ranked alphabetically within NCCN therapy categories. The report also highlights important disease-relevant genes with no reportable alterations identified and genomic alterations associated with potential resistance to therapy to help rule out potentially ineffective treatment.5 Reports vary according to regional differences, e.g. EU reports list EU-approved therapy options to support clinical decision-making.§
