Foundation Medicine, Inc. (NASDAQ:FMI) today announced that the U.S. Food and Drug Administration (FDA) granted a Breakthrough Device designation (formerly Expedited Access Pathway program) for its new liquid biopsy assay, which is an expanded version of its FoundationACT® assay. The new assay will include more than 70 genes and genomic biomarkers for microsatellite instability (MSI) and blood tumor mutational burden (bTMB). If approved, this test could be the first FDA-approved liquid biopsy assay to incorporate multiple companion diagnostics (CDx) and multiple biomarkers to inform the use of targeted oncology therapies, including immunotherapies.

“Liquid biopsies are becoming an increasingly important option to inform personalized treatment decisions for patients with advanced cancer. A critical need exists for non-invasive solutions for these patients to help guide the use of both targeted and immunotherapies. After successfully completing the parallel review process with FoundationOne CDx™ for solid tumors, we’re pleased to continue our work with the FDA applying this expertise to our liquid biopsy franchise with the potential to offer oncologists multiple FDA-approved options that enable biomarker-driven care and ultimately better outcomes for patients,” said Vincent Miller, M.D., chief medical officer at Foundation Medicine. “The acceptance of this assay for Breakthrough Device designation is an important step to advancing precision medicine options for patients, including the potential intended use as a companion diagnostic across multiple types of cancer, which will also help our biopharma partners accelerate their development efforts for these programs.”

The new liquid biopsy assay is a next generation sequencing-based in-vitro diagnostic device for the detection of substitutions, insertion and deletion alterations (indels), copy number alterations (CNAs) and select gene rearrangements, as well as genomic signatures including microsatellite instability (MSI) and blood tumor mutational burden (bTMB) using circulating cell-free DNA (cfDNA) isolated from plasma derived from peripheral whole blood. The company plans to seek approval of the assay for use as a companion diagnostic to identify patients who may benefit from treatment with certain targeted therapies in accordance with the approved therapeutic product labeling and to provide tumor mutation profiling to be used by qualified health care professionals following the professional guidelines in oncology for patients with malignant neoplasms.

The FDA granted Foundation Medicine's request for Breakthrough Device designation because it met the criteria necessary for inclusion in the program, one of which is the large unmet medical need for comprehensive genomic profiling of tumors for cancer patients for whom a tissue sample is unavailable for testing. Under the Breakthrough Device Program, the FDA works with device sponsors to try to reduce the time and cost from development to an approval decision.
