NfL test for multiple sclerosis

Quanterix Granted Breakthrough Device Designation from U.S. FDA

Blood-based assay has the potential to serve the multiple sclerosis (MS) community in management of relapsing-remitting form of the disease

April 22, 2022 08:30 AM Eastern Daylight Time: Quanterix Corporation, a company digitising biomarker analysis with the goal of advancing the science of precision health, announced that its Simoa® neurofilament light chain (NfL) plasma test has been granted Breakthrough Device designation by the U.S. Food and Drug Administration (FDA) as a prognostic aid in assessing the risk of disease activity in patients diagnosed with relapsing-remitting MS (RRMS).

The FDA’s Breakthrough Device designation is granted to products that have the potential to offer more effective diagnosis or treatment of life-threatening diseases with an unmet medical need. The programme 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. However, Breakthrough Device designation does not guarantee that the FDA review and approval process will be shortened or that an application will be approved.

The Quanterix Simoa® NfL test is a digital immunoassay that quantitatively measures NfL in human serum and plasma and shows promise to be used in conjunction with clinical, imaging and laboratory findings as an aid in identifying RRMS patients who are at lower or higher risk for relapse within four years. This prognostic information could be useful in tailoring the therapeutic approach to more effectively treat the disease.

The designation comes on the heels of a large-scale, international study published in The Lancet Neurology, in which researchers from the University Hospital Basel and University of Basel leveraged Quanterix’ ultra-sensitive Simoa® technology to help establish a new method for clinicians to identify and interpret elevated values of sNfL in individual MS patients. Along with this research, the Simoa® NfL assay was referenced in at least 20 studies presented at the American Academy of Neurology (AAN) 74th Annual Meeting, further validating the biomarker’s potential utility.

“There has been an ever-growing body of research with the Simoa® NfL blood test supporting NfL as a reliable biomarker for MS disease activity prognosis and treatment response monitoring,” said Dr. Mark S. Freedman, Professor of Neurology and Director of Multiple Sclerosis Research at the Ottawa Hospital.

The FDA’s grant of Breakthrough Device designation for this test has the potential to help the multiple sclerosis community further advance the optimal use of NfL measurements in both research and clinical practice aimed at more effective therapeutic management of the disease for the millions of patients suffering from the condition.

This is the second test from Quanterix to receive Breakthrough Device status – the company’s phospho-Tau 181 (pTau-181) assay for Alzheimer’s disease received the designation in 2021.
