Quanterix To Unveil Groundbreaking Neurodegenerative Disease Research And Strategic Partnership At Neuroscience 2016

Lexington, Mass. — Quanterix Corporation, a company digitizing biomarker
analysis to advance the science of precision health, today announced a strategic collaboration with
UmanDiagnostics AB, a company specializing in the early detection of brain diseases, to provide
commercial access to a Simoa ultrasensitive NeuroFilament Light (Nf-L) assay. Additionally, the company
today unveiled that researchers from the University of Mississippi Medical Center and the German
Center for Neurodegenerative Disease, will present new results from research conducted using
Quanterix’ Simoa technology at Neuroscience 2016on November 12 – 16, 2016 in San Diego, CA.

Neurodegenerative diseases, such as Alzheimer’s Disease and Parkinson’s Disease, are currently
incurable and have debilitating conditions that result in progressive neurodegeneration, which may start
20-30 years before symptoms are noticed. Developing specific, sensitive and predictive biomarkers is
one of the major challenges so far for establishing therapeutic treatment for these diseases. The major
barrier is a lack of highly sensitive and reliable tools to measure the gradient difference of molecules in
the bloodstream at the pre-symptomatic stage. Many of the critical neurology health related
biomarkers, including Nf-L, are not present in high enough concentrations in the blood to be detected
with standard assay technology today.

Quanterix’ digital health solution, Simoa, solves this problem by giving researchers the ability to closely
examine critical biomarkers simultaneously, in a hypersensitive and reliable manner. The strategic
partnership with UmanDiagnostics will provide researchers and clinicians with commercial access to the
most sensitive NeuroFilament Light (Nf-L) assay available on the market, which will improve detection
and diagnosis capabilities in neurology.

“We are extremely pleased to be working closely with Quanterix to provide Uman’s highly specific Nf-L
antibodies for use in the Simoa assay format. This enables the world’s most specific and sensitive assay
for Nf-L,” said Dr. Niklas Norgren, CEO, UmanDiagnostics. “The Simoa Nf-L assay is capable of detecting
this highly informative neuronal damage biomarker directly in blood, enabling simplified assessment of a
variety of neurological disorders, such as Alzheimer’s, Parkinson’s, Multiple Sclerosis, and potentially a
critical way to access concussion-related neurological issues.”

“This year’s Neuroscience event is a great opportunity for researchers to showcase groundbreaking
discoveries in several different areas of neurology and an appropriate forum for us to unveil our
partnership with UmanDiagnostics,” said Kevin Hrusovsky, CEO and Executive Chairman, Quanterix. “Our
collaboration with UmanDiagnostics will provide critical, commercial availability of our Simoa-based
assay, which can detect and quantify Nf-L in blood. We look forward to advancing research with this
sensitive assay and uncovering groundbreaking discoveries in neurology disease. We’re also excited to
take part in this innovative conference and collaborate with leading scientists in the field to transform
the way in which we detect and treat neurodegenerative disease in the future.”

Nanosymposium Session Details:

“Using a Single Molecule Digital Analyzer to Measure Blood Based Biomarkers for Neurodegenerative Diseases”
When: Saturday, November 12, 2016, 1:00 – 1:15 p.m. PT
Where: San Diego Convention Center, Room 32B
Authors: J. Wang, Department of Pathology, University of Mississippi Medical Center, Q. Zhang,
B. Zheng, J. Lage, C. Stockmeier, T. Mosley, University of Mississippi Medical Center

Session Abstract: 

Using Quanterix technology, these researchers have successfully developed an
ultra-sensitive, single molecule digital analyser platform which can measure the molecules in
plasma and tissue homogenates at serial pg/ml to fg/ml in a very reliable manner – R square
values are as high as 99 in serial dilution tests. They’ve now successfully established the tests for
several cytokines and also for a neurosteroid allopregnanolone in human plasma samples.
Further spike and recovery experiments in diluted samples help them to accurately measure the
spiked samples in calibrator into those diluted brain samples (recovery 70-93%). The high
sensitivity also indicates that these molecules can be measured in a small size quantity/volume
(less than 200μ) of samples. Therefore, the highly sensitive and reliable measurement platform
can be used to determine the blood based, early changes of bioactive molecules for
neurodegenerative disease. The results will also provide targets for developing therapeutic
strategies for these neurodegenerative diseases.

Presentation Abstract: 

The inhibition of the beta-site amyloid precursor protein-cleaving
enzyme 1 (BACE1) is a main therapeutic approach for the treatment of Alzheimer’s disease. The
characterization of BACE1 inhibitors has largely focused on direct effects, (i.e. the reduction of
β-amyloid (Aβ) generation and deposition in the brain). These researchers previously reported
an age-related increase of tau protein in the cerebrospinal fluid (CSF) of Aβ precursor protein
(APP) transgenic mice reminiscent of changes in the CSF of AD patients. Using a novel highsensitivity
tau sandwich immunoassay they now demonstrate that BACE1 inhibition prevents
CSF tau increase both in early-depositing APP tg mice and APP tg mice with moderate Aβ
pathology. Their results demonstrate that BACE1 inhibition not only reduces Aβ generation but
also downstream AD pathophysiology. The tight correlation between Aβ aggregation in brain
and tau levels in CSF renders CSF tau a valuable marker to predict the effectiveness of BACE1
inhibitors in current clinical trials.

Quanterix will also be hosting a webinar with Dr. Michelle M. Mielke, Professor of Epidemiology and
Neurology, The Mayo Clinic, and Dr. Stephan Käser, HIH Hertie Institute for Clinical Brain Research, on
Friday December 2, 2016 at 11:00 a.m. EST on novel CNS biomarker applications enabled by Simoa. The
webinar will highlight the use of a Simoa custom assay and the commercial tau assay for different
applications in mouse and human studies in both cerebrospinal fluid (mouse) and blood (humans). To learn more about the webinar and register, please visit here.
