On May 20, 2020 Foundation Medicine, Inc. reported that it has received approval from the U.S. Food and Drug Administration (FDA) for FoundationOneCDx to be used as a companion diagnostic for LYNPARZA (olaparib), which was also approved today in the U.S. for adult patients with deleterious or suspected deleterious germline or somatic homologous recombination repair (HRR) gene-mutated metastatic castration-resistant prostate cancer (mCRPC) who have progressed following prior treatment with enzalutamide or abiraterone (Press release, Foundation Medicine, MAY 20, 2020, View Source [SID1234558340]). FoundationOne CDx is the only FDA-approved comprehensive genomic profiling (CGP) test for all solid tumors that incorporates multiple companion diagnostic claims.

Prostate cancer is the second most common cancer in men; 1 in 9 will be diagnosed during their lifetime.1 mCRPC occurs when prostate cancer grows and spreads to other parts of the body despite the use of androgen-deprivation therapy to block the action of male sex hormones.2 Because there have previously been limited treatment options for this specific disease area, there is generally a high mortality rate.

"This therapy and companion diagnostic approval underscores the value of comprehensive genomic profiling in advanced cancer patients as it validates our ability to identify alterations in the 14 HRR pathway genes within FoundationOne CDx’s 324 gene panel that indicate a patient may be eligible for treatment with Lynparza, a process not possible through single gene or hot spot testing," said Brian Alexander, M.D., M.P.H., chief medical officer at Foundation Medicine. "This is an important advancement for patients with HRR-mutated metastatic castration-resistant prostate cancer, as there have previously been limited treatment options available for this specific condition."

FoundationOne CDx is the first FDA-approved broad companion diagnostic that is clinically and analytically validated for solid tumors. FoundationOne CDx is currently approved as a companion diagnostic for more than 20 targeted therapies.

LYNPARZA was approved based on the PROfound study, which was supported by Foundation Medicine and was the first phase III biomarker-selected study using a molecularly targeted treatment in men with metastatic castration-resistant prostate cancer (mCRPC) to demonstrate improved outcomes. The PROfound trial is the largest prospective study to date performing central tissue testing for homologous recombination repair (HRR) gene mutations in mCRPC patients. The clinical trial assay (CTA) is an NGS assay based on FoundationOne CDx.

LYNPARZA is jointly developed and commercialized by AstraZeneca (LSE/STO/NYSE: AZN) and Merck & Co., Inc.

About FoundationOne CDx

FoundationOne CDx is a next-generation sequencing based in vitro diagnostic device for detection of substitutions, insertion and deletion alterations (indels), and copy number alterations (CNAs) in 324 genes and select gene rearrangements, as well as genomic signatures including microsatellite instability (MSI) and tumor mutational burden (TMB) using DNA isolated from formalin-fixed paraffin embedded (FFPE) tumor tissue specimens. FoundationOne CDx is for prescription use only and is intended as a companion diagnostic to identify patients who may benefit from treatment with certain targeted therapies in accordance with their approved therapeutic product labeling. Additionally, FoundationOne CDx is intended to provide tumor mutation profiling to be used by qualified health care professionals in accordance with professional guidelines in oncology for patients with solid malignant neoplasms. 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. Some patients may require a biopsy.
