Quanterix Serum Nf-L Assay Powers Key Trial and Study Results Presented at ECTRIMS 2019

Quanterix Corporation (NASDAQ: QTRX), a company digitizing biomarker analysis to advance the science of precision health, today announced that its Simoa technology and Nf-L assays were used in many of the groundbreaking research and treatment developments presented at the 35^th Congress of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS). The conference was held from Sept. 11-13, 2019 in Stockholm, Sweden. Prior to the beginning of the conference, Quanterix announced that presentations leveraging Simoa increased by 40 percent from the 2018 ECTRIMS event, to a total of 49 references. The widespread adoption of Quanterix’ technology demonstrates the value it brings to advancing disease diagnosis and monitoring for Multiple Sclerosis.

Major Serum Nf-L highlights from ECTRIMS included:

• Powering Drug Trials: Novartis announced that its Phase III ASCLEPIOS trials demonstrate the efficacy of ofatumumab in patients with relapsing MS. Nf-L using Simoa was used as a secondary endpoint and showed reductions after just three months of treatment.
• Therapeutic Effectiveness: Several industry presentations on efficacy and comparative effectiveness of existing disease-modifying therapies in MS included data on Nf-L. Roche announced results of retrospective analyses of its Phase III OPERA I, OPERA II and ORATORIO trials for patients with relapsing-remitting or primary progressive MS treated with Ocrevus, who saw serum Nf-L levels (measured with Simoa) lowered to those of healthy donors. These reductions in Nf-L were accompanied by significant reductions in wheelchair use and disease activity progression.
• Revealing Biology of Disease: Several studies, including recently published data in the Journal of American Medicine (JAMA) Neurology provided greater insights into the biology of MS, connection between inflammation and neurodegeneration, understanding the genetics of MS severity, and how additional Simoa assays such as GFAP can be combined with Nf-L for even greater insights. One study showed serum Nf-L levels rising six years before the onset of MS, suggesting a possible role for the test as an early marker of neuronal damage.
• Moving from Research to the Clinic: Numerous studies were presented further strengthening the role of serum Nf-L as a prognostic and treatment monitoring tool in MS, and supporting future implementation for clinical use. Biogen released data generated in collaboration with Siemens Healthineers using Quanterix/UmanDiagnostics Nf-L antibodies to adapt the Simoa assay onto a routine analyzer platform, bringing promise to a future IVD assay.

“The research presented at ECTRIMS is critical to the MS community. The use cases of Nf-L as a valuable biomarker are growing rapidly,” said Kevin Hrusovsky, CEO, President and Chairman of Quanterix. “Our partnerships with the top academic institutions, research organizations and pharmaceutical companies, in conjunction with our acquisition of UmanDiagnostics, are providing an important opportunity for scientific breakthroughs, which may someday change the lives of patients around the globe.”
