Quanterix Granted Breakthrough Device Designation from U.S. FDA for Blood-Based pTau-181 Assay for Alzheimer’s Disease

BILLERICA, Mass.–(BUSINESS WIRE)–Quanterix Corporation (NASDAQ: QTRX), a company digitizing biomarker analysis with the goal of advancing the science of precision health, announced today that its Simoa® phospho-Tau 181 (pTau-181) blood test has been granted Breakthrough Device designation by the U.S. Food and Drug Administration (FDA) as an aid in diagnostic evaluation of Alzheimer’s Disease (AD). The FDA’s Breakthrough Device designation is granted to products that have the potential to offer more effective diagnosis of life-threatening diseases with an unmet medical need. The program is designed to enable accelerated development, assessment and review processes, with the intention to provide patients with more timely access to breakthrough technologies or devices.

“Quanterix’s technology has the unique ability to detect low-abundance markers in a blood sample, unlocking the possibility for earlier, more accessible, non-invasive diagnosis of disease, including AD. The breakthrough designation represents an important step in our long-term strategy to develop ultra-sensitive in vitro diagnostics,” said Kevin Hrusovsky, Chairman and CEO, Quanterix Corporation. “More importantly, it further validates the potential of our ultrasensitive Simoa technology, and we remain deeply committed to leveraging our innovative platform to support advances in neurodegenerative research and the translation of breakthrough scientific discoveries into the clinic. Our Research Use Only assays, including our Simoa pTau-181 assay, remain important tools in supporting these advances.”

The Simoa pTau-181 test is a semiquantitative immunoassay intended for the measurement of pTau-181 concentration in human serum and plasma using the Quanterix HD-X immunoassay system. Proposed indications under the Breakthrough Device designation include use of the test results in adult patients, aged 50 years and over, presenting with cognitive impairment who are being evaluated for AD and other causes of cognitive decline as an aid in diagnostic evaluation for AD. The test is not intended as a stand-alone diagnostic assay and test results will be interpreted in conjunction with other diagnostic tools to establish a final clinical diagnosis. Breakthrough Device designation does not guarantee that the FDA review and approval process will be shortened or that an application will be approved.
