FoundationOne Liquid CDx analyzes the largest genomic region of any FDA-approved comprehensive liquid biopsy test and was approved in August to provide tumor mutation profiling in accordance with professional guidelines for patients with any solid tumor. Concurrently, it was approved as a companion diagnostic for a poly (ADP-ribose) polymerase (PARP) inhibitor approved by the FDA for the treatment of metastatic castration-resistant prostate cancer patients with qualifying BRCA1/2 alterations, and for three first-line EGFR tyrosine kinase inhibitors (TKIs) for the treatment of non-small cell lung cancer patients.

FoundationOne Liquid CDx offers oncologists an important and minimally invasive tool to consider when making treatment decisions for their patients, regardless of the type of cancer they have, said Brian Alexander, M.D., M.P.H., chief medical officer at Foundation Medicine. These three additional companion diagnostic claims expand the tests clinical utility into breast and ovarian cancer, demonstrating our commitment to bringing precision medicine to more patients, and we plan to continue working with our biopharma partners to increase that reach.

Todays approval expands FoundationOne Liquid CDxs companion diagnostic indications to include the following targeted therapies:

PIK3CA is the most commonly mutated gene in HR+/HER2- breast cancer; approximately 40% of patients living with HR+/HER2- breast cancer have this mutation.1

An estimated one in four women with epithelial ovarian cancer have a mutation of the BRCA1 or BRCA2 gene.2

Using a blood sample, FoundationOne Liquid CDx analyzes over 300 cancer-related genes for genomic alterations. FoundationOne Liquid CDx results are delivered in an integrated report that identifies alterations matched to FDA-approved therapies. It also enables accelerated companion diagnostic development for biopharma companies developing precision therapeutics.

As a laboratory professional service which has not been reviewed or approved by the FDA, the FoundationOne Liquid CDx report delivers information about the genomic signatures microsatellite instability (MSI) and blood tumor mutational burden (bTMB), as well as single gene alterations, including NTRK fusions, to help inform the use of other therapies including immunotherapies. Also, as a laboratory professional service, the report provides relevant clinical trial information and includes interpretive content developed in accordance with professional guidelines in oncology for patients with any solid tumor.

About FoundationOne Liquid CDx

FoundationOne Liquid CDx is a qualitative next generation sequencing based in vitro diagnostic test for prescription use only that uses targeted high throughput hybridization-based capture technology to analyze 324 genes utilizing circulating cell-free DNA (cfDNA) isolated from plasma derived from anti-coagulated peripheral whole blood of advanced cancer patients. The test is FDA-approved to report short variants in over 300 genes and is 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. Patients who are negative for companion diagnostic mutations should be reflexed to tumor tissue testing and mutation status confirmed using an FDA-approved tumor tissue test, if feasible.
