• Agreement provides Quanterix a license to extensively studied p-Tau 217 antibodies to enable global access to plasma-based testing for Alzheimer’s Disease research and diagnostics

BILLERICA, Mass. / Oct 23, 2023 / Business Wire / Quanterix Corporation (NASDAQ: QTRX), a leading provider of ultra-sensitive research products and high-definition diagnostics, today announced the signing of a license agreement with Janssen Sciences Ireland UC (Janssen), a Johnson & Johnson (J&J) Company. Under this agreement, Quanterix will receive worldwide, non-exclusive rights to J&J’s extensively studied p-Tau 217 antibodies and assay designs for potential use in clinical research and diagnostic products, further strengthening Quanterix’s position at the forefront of the Alzheimer's Disease (AD) biomarker field.

Under the terms of the license agreement, Janssen will grant Quanterix a worldwide non-exclusive license for J&J-developed technology to produce Simoa p-Tau 217 research-use only (RUO) assay kits for global distribution. Furthermore, under the agreement Quanterix will launch a Laboratory Developed Test (LDT) based on the J&J p-Tau 217 antibodies and assay, offered through Accelerator under the Lucent Diagnostics brand. These advances mark a significant milestone for Quanterix's continued leadership in advancing Alzheimer's Disease diagnosis and treatment, providing a path for the first scalable immunoassay-based p-Tau 217 test to potentially become widely available to researchers and clinicians.

p-Tau 217 has emerged as a top performing biomarker for AD, enabling clinical sensitivity and specificity in blood¹. Highly sensitive and specific blood-based biomarker tests may improve diagnosis by expanding access to treatments for millions of individuals with early Alzheimer’s Disease, which is currently detected using positron emission tomography (PET) or lumbar puncture for CSF biomarkers. These methods are expensive, lack wide availability, and are invasive. There is growing consensus that high performing blood-based biomarker tests may be an appropriate alternative for patient care.

"This collaboration demonstrates the scientific advances that are possible when Simoa’s ultra-sensitive detection is combined with clinically validated antibodies and critical reagents,” said Masoud Toloue, CEO of Quanterix. “Providing access to high-performing blood-based p-Tau 217 assays are an important step as we work with several partners to build the global infrastructure for non-invasive testing of Alzheimer’s Disease.”
