Genes and genomic signatures

FoundationOne Liquid CDx reports >300 genes and is able to detect both novel and known variants, including four classes of genomic alterations (base substitutions, insertions or deletions, copy number alterations and gene rearrangements), genomic signatures (MSl, bTMB) and Tumour Fraction, to provide prognostic, diagnostic and predictive insights that inform research or treatment decisions for individual patients across all solid tumours.‡1,2

Faster treatment decisions

Quick and convenient single blood draw helps avoid invasive biopsies and enables faster treatment decisions1,28

FoundationOne Liquid CDx requires only two tubes of b lood from a single blood draw (2 x 8.5 ml whole blood) and has a turnaround time of less than 2 weeks from receipt of the sample at our laboratory to report, thereby allowing informed treatment decisions to be made faster.1-28

This may help reduce distress that patients may experience from long waiting times for scheduling a biopsy and receiving the results associated with tissue-based testing.12-15

FoundationOne Liquid CDx has demonstrated strong clinical utility

Our previous blood-based comprehensive genomic test demonstrated clinical utility for treatment selection at diagnosis in metastatic NSCLC in BFAST (Blood First Assay Screening Trial), a global, prospective cohort study.30-39
ALK+ prevalenceThe proportion of patients identified as ALK+ using blood-based testing (BFAST) was comparable to that previously reported using tissue-based testing (meta-analysis, range among Western populations)30,40LIQUID5.4%4.5%–6.4%TISSUE

BFAST used an earlier version of Foundation Medicine's current liquid biopsy service, FoundationOne Liquid CDx. The assay used in BFAST for measuring o f ALK+ has been incorporated into FoundationOne Liquid CDx. For concordance results between these two tests, please see our ful l intended use at: www.foundationmedicine.com/F1LCDx.

In-depth report

A clear, in-depth report provides insights on your patient's genomic profile as well as associated targeted therapies, immunotherapies and relevant clinical trials1,2.4-11,41

Approved targeted therapies and immunotherapies for the patient's genomic alterations and biomarkers are ranked alphabetically within NCCN Categories of Preference (for additional information on the NCCN therapy categories please refer to the NCCN Compendium® at www.nccn.org). Reports vary according to regional differences, e.g. EU reports list EU-approved therapy options to support clinical decision-making.‖41

When using different Foundation Medicine services across the patient journey, consistency of the reports aid comparison of the results.41,42

Up to five previous tests may be shown. For some genes in FoundationOne Liquid CDx, only select exons are assayed. Therefore, an alteration found by a previous test may not have been confirmed despite overlapping gene lists. Please refer to the Appendix for the complete list of genes and exons assayed. The gene and biomarker list will be updated periodically to reflect new knowledge about cancer biology. As new scientific information becomes available, alterations that had previously been listed as Variants of Unknown Significance (VUS) may become reportable. Tissue Tumor Mutational Burden (TMB) and blood TMB (bTMB) are estimated from the number of synonymous and non-synonymous single-nucleotide variants (SNVs) and insertions and deletions (indels) per area of coding genome sampled, after the removal of known and likely oncogenic driver events and germline SNPs. Tissue TMB is calculated based on variants with an allele frequency of ! 5%, and bTMB is calculated based on variants with an allele frequency of ! 0.5%. Not Tested = not baited, not reported on test, or test preceded addition of biomarker or gene Not Detected = baited but not detected on test Detected = present ( = Cannot Be Determined = Sample is not of sufficient data quality to confidently determine biomarker status NOTE Electronically Signed by Julia A.
