Quanterix Launches the First Comprehensive Multiplex Panel to Study Traumatic Brain Injury Severity


New panel offers unmatched sensitivity to simultaneously measure four proven neurological protein biomarkers in blood and cerebrospinal fluid within a single test

LEXINGTON, Mass. — May 17, 2017 Quanterix Corporation, a company digitizing biomarker analysis to advance the science of precision health, today announced the launch of the Simoa™ Neurology 4-Plex A assay (N4PA). The Simoa N4PA assay is the first test that can simultaneously measure four protein biomarkers from either cerebrospinal fluid (CSF) or directly from blood samples for the study of traumatic brain injury (TBI) and other neurodegenerative conditions. The four biomarkers used on the panel include neurofilament light (NF-L), tau, glial fibrillary acidic protein (GFAP) and ubiquitin carboxyl-terminal hydrolase L1 (UCH-L1). Launch of the Simoa N4PA panel will be highlighted this week in Boston at Brain Trust: Pathways to InnoVAtion, the 2nd annual event hosted by the Department of Veteran Affairs (VA).

Recent studies indicate that serum NF-L is a biomarker for mild TBI in amateur boxers and professional hockey players1, that plasma tau is related to concussion severity and return-to-play2, and that serum GFAP and UCH-L1 can detect mild to moderate TBI.3 The TBI Endpoints Development (TED) Initiative has also hosted a 2017 Consensus Conference, where thought leaders have identified NF-L, tau, GFAP and UCH-L1 as the top four fluid biomarkers of interest for mild TBI assessment.

“The Simoa N4PA panel is an essential research tool for assessing head trauma-induced neural damage, particularly mild cases of TBI, which are the hardest to detect,” said Kevin Hrusovsky, Executive Chairman and Chief Executive Officer at Quanterix. “The assay is the first of its kind to detect all four key neuro biomarkers linked to TBI. This can be done simultaneously in a single well, at 1/1000th of the concentration level required by traditional ELISAs. As a result of continued product advances, we plan to usher this ultrasensitive multiplex technology into the clinic, and develop the most accurate and predictive tests for neurological disorders. So many people in this world suffer from head trauma and its deleterious effects. Our digital biomarker tests could revolutionize objective testing and lead to a new standard of care for treating concussions and neurodegenerative disease.”

The assay’s high degree of sensitivity allows the use of blood serum or blood plasma to detect neurological biomarkers, in place of conventional CSF sampling that is invasive and painful. Similarly, ultra-low level detection enables measuring biomarkers, from early/mild stages to severe impairment. “The design of this multiplexed assay will provide researchers with the insights needed to speed the development of a new generation of diagnostic products that will hopefully be useful for early detection of neurological disease,” said Henrik Zetterberg, M.D., Ph.D., Professor of Neurochemistry and Head of the Department of Psychiatry and Neurochemistry, Sahlgrenska Academy, University of Gothenburg.

“Comparing the diagnostic and prognostic utility of tau, NF-L, UCHL-1 and GFAP head-to-head in samples collected at different time points following traumatic brain injury will give us new information on how we could potentially use these markers in clinical practice.”

The Simoa N4PA assay is for research use only and not for use in diagnostic procedures. The assay kit includes Simoa reagents, calibrators, multiplex Simoa beads, detector antibodies, and sample diluent required to run up to 96 tests. It is available for immediate purchase to run on the Simoa HD-1 Analyzer or via the Simoa Accelerator Lab, an innovation center for biomarker research, custom assay development and clinical sample testing.

Research and development of neurological tests including the Simoa N4PA assay is a result of two GE and NFL Head Health Challenge grants that have been awarded to Quanterix since 2015.

Sourcing Commercial Drugs for Clinical Trials: US vs. EU Understanding the Differences


Sourcing commercial drugs for clinical trials is a dynamic process. There are many factors to consider: single source or regional sourcing, strategy, price, supply availability, lead times, and documentation are just a few. In the past, there were fewer clinical trials that required commercial drug sourcing, so demand was not as high. Today, the demand for commercial drugs in clinical trials has greatly increased and, as a result, inventory is tighter, orders are monitored more closely by manufacturers, and lead times have increased. This report highlights the key differences in sourcing from the US and EU.
