FoundationOne®Liquid CDx is an FDA-approved companion diagnostic that analyzes guideline-recommended genes from a simple blood draw. It is the only FDA-approved blood-based test to analyze over 300 genes**—making it the most comprehensive FDA-approved liquid biopsy on the market. Plus, as a professional service, which has not been reviewed or approved by the FDA, this test reports blood tumor mutational burden (bTMB), microsatellite instability high (MSI-H), and tumor fraction values1.
With targeted therapy options, comprehensive genomic profiling with FoundationOne Liquid CDx can help guide treatment strategies and help predict patient benefit across multiple cancer indications. Foundation Medicine’s test portfolio enables you to easily reflex FoundationOne Liquid CDx, a blood-based test, to FoundationOne®CDx, a tissue-based test, or vice versa.‡
Coverage includes:
With such broad coverage, 87% -- or nearly 9 out of 10 patients -- pay $0 for testing.5
Over 300 genes, bTMB, and MSI-H1 Includes guideline-recommended genes and biomarkers to help guide therapy selection and identify clinical trial options for patients with solid tumors.

Our portfolio of tests analyzes genes and biomarkers for relevant alterations in patients with NSCLC, including EGFR, ALK, ROS1, BRAF, NTRK, METex14, PD-L1† and genomic signatures like TMB.‡
It’s always been an ambitious concept: By analyzing a patient’s blood, doctors might better understand their individual cancer, and thus better pinpoint what treatment options may be most effective. But yesterday’s ambition has become today’s reality—we’re living in an exciting time for this kind of test, known as liquid biopsy.
Our portfolio of tests analyzes all guideline-recommended genes and biomarkers for relevant alterations in patients with prostate cancer including: BRCA1, BRCA2, ATM, PALB2, FANCA, RAD51D, CHEK2, CDK12, and genomic signatures like MSI.§

Are your negative liquid biopsy results really negative?
FoundationOne®Liquid CDx reports include ctDNA tumor fraction*** as a professional service which has not been reviewed or approved by the FDA.
ctDNA tumor fraction is a determination of the amount of circulating tumor DNA as a fraction of total cell free DNA in a blood sample that accounts for aneuploidy, variant allele frequency, fragment length information, clonal hematopoiesis predictions and known tumor-associated alterations.
When FoundationOne Liquid CDx ctDNA tumor fraction is low and results are negative, reflexing to tissue may find actionable gene alterations (52% more actionable alterations in NSCLC6).
Next steps in patient care protocols tend to be more clear with positive results. However, when liquid biopsy results are negative, be better informed with ctDNA tumor fraction.
CGP liquid biopsies require detectable ctDNA in blood to be able to identify actionable alterations. When ctDNA tumor fraction was low, Foundation Medicine’s tissue CGP found previously unidentified alterations in 52% of patients with driver-negative FoundationOne®Liquid CDx results.6
Foundation Medicine reports circulating tumor DNA (ctDNA) tumor fraction as a percentage when ctDNA tumor fraction is 1% or greater.
Blood samples with high ctDNA tumor fraction have sufficient circulating tumor DNA (ctDNA) content to have confidence in negative results, increasing the likelihood that a genomic alteration will be identified by FoundationOne Liquid CDx if it exists. Such samples are at lower risk of producing false negative results.
high ctdna TUMOR FRACTION (≥1%) VALUES MEAN THAT THERE IS IMPROVED CONCORDANCE WITH TISSUE TESTING.
WHEN LIQUID BIOPSY (LBX) RESULTS ARE NEGATIVE AND ctdna TUMOR FRACTION IS LOW (<1%) ADDITIONAL TISSUE CGP MAY UNCOVER ACTIONABLE FINDINGS.
bTMB, MSI-H status, and ctDNA tumor fraction are reported as a laboratory professional service which is not reviewed or approved by the FDA.
A study investigating whether algorithmic quantification of ctDNA in a liquid biopsy (LBx) sample can increase confidence in negative LBx results, reducing need for confirmatory tissue biopsy testing.6
FoundationOne Liquid CDx results from NSCLC patients were analyzed and their ctDNA tumor fraction values recorded. All samples were then reflexed to FoundationOne®CDx to identify any additional actionable findings.6
Distribution of FoundationOne Liquid CDx ctDNA tumor fraction for subset of driver negative liquid biopsy samples (n=80).
When FoundationOne Liquid CDx results were negative and ctDNA tumor fraction was Low, reflexing to tissue testing with FoundationOne CDx found previously unidentified alterations in 52% of patient samples.6
When ctDNA tumor fraction was High, reflexing to tissue testing with FoundationOne CDx found no additional actionable alterations.6

***Foundation Medicine’s ctDNA tumor fraction is a determination of the amount of circulating tumor DNA as a fraction of total cell free DNA in a blood sample that accounts for aneuploidy, variant allele frequency, fragment length information, clonal hematopoiesis predictions and known tumor-associated alterations. ctDNA tumor fraction is reported as a laboratory professional service which has not been reviewed or approved by the FDA.
**FoundationOne®Liquid CDx is FDA-approved to report substitutions and indels in 311 genes, including rearrangements in ALK and BRCA1/2 and copy number alterations in BRCA1/2 and ERBB2 (HER2). Comprehensive results across all 324 genes are reported as a laboratory professional service which is not reviewed or approved by the FDA.
‡ When “Portfolio Reflex” is selected on the test requisition form (TRF), Foundation Medicine will proceed with the initial test and if the specimen does not meet the criteria for successful testing, we will automatically reflex to the other test and procure a new specimen.
✝ Sensitivity is high for short variants and fusions when ctDNA tumor fraction is ≥1%. Copy number amplifications and deletions of exons or genes are detectable across a range of ctDNA
tumor fraction values and reflexing to FoundationOne CDx may provide additional findings when these types of alterations report negative. (Refer to the FoundationOne Liquid CDx
product label for additional information.)

FoundationOne®Liquid CDx is for prescription use only and is a qualitative next-generation sequencing based in vitro diagnostic test for cancer patients with solid tumors. The test analyzes 324 genes utilizing circulating cell-free DNA and is FDA-approved to report short variants in 311 genes and as a companion diagnostic to identify patients who may benefit from treatment with specific therapies (listed in Table 1 of the Intended Use) in accordance with the approved therapeutic product labeling. Additional genomic findings may be reported and are not prescriptive or conclusive for labeled use of any specific therapeutic product. Use of the test does not guarantee a patient will be matched to a treatment. A negative result does not rule out the presence of an alteration. When considering eligibility for certain therapies for which FoundationOne Liquid CDx is a companion diagnostic, testing of plasma is only appropriate where tumor tissue is not available. Patients who are negative for other companion diagnostic mutations should be reflexed to tumor tissue testing and mutation status confirmed using an FDA-approved tumor tissue test, if feasible.

FoundationOne®Tracker is a clinical test performed exclusively as a laboratory service. This test has not been cleared or approved by the U.S. Food and Drug Administration (FDA). FoundationOne Tracker is a personalized assay for oncology that is based on patient-specific somatic variants (substitutions and short insertions/deletions) identified from baseline tumor tissue testing and used to detect and longitudinally measure plasma circulating tumor DNA (ctDNA) abundance as a biomarker for tumor burden. Treatment decisions are the responsibility of the treating physician. ctDNA detection sensitivity may be limited if blood collection occurs within two weeks of surgery or while a patient is on therapy. A negative test result does not definitively indicate the absence of cancer. This test is not designed to detect or report germline variation, nor does it infer hereditary cancer risk for a patient. This test is designed to detect ctDNA from the assayed tumor only; new primary tumors will not be detected. This test is expected to have limited sensitivity in some cancer types due to limited ctDNA shed.
