LucentAD^TM Complete improves on single biomarker tests, significantly reducing the intermediate zone, providing results for more patients

BILLERICA, Mass.--(BUSINESS WIRE)--Oct. 28, 2024-- Lucent Diagnostics, a brand of Quanterix Corporation (NASDAQ: QTRX), has introduced LucentAD Complete, a new multi-marker blood test designed to help detect Alzheimer’s Disease (AD) in a broader range of patients.

Recent Alzheimer’s Association criteria for diagnosing Alzheimer’s recommend that plasma p-Tau 217 tests be designed with two cutoffs to confidently differentiate between patients with or without amyloid pathology, a hallmark of AD. However, this approach leaves an “intermediate zone” of uncertainty, requiring patients that fall into this zone follow up with cerebral spinal fluid measurement via invasive lumbar puncture or costly amyloid PET scans. LucentAD Complete addresses this by reducing the number of patients that fall into the intermediate zone by threefold. The test uses a proprietary algorithm to score five AD-related biomarkers (p-Tau 217, Aβ42/40, NfL, GFAP) providing significantly better amyloid classification compared to single-marker tests alone.

“In over 1,000 patients across three independent clinical cohorts, we achieved guideline performance standard for a blood-based Alzheimer’s diagnostic test, while significantly increasing conclusive results for more patients versus p-Tau 217 alone,” said Masoud Toloue, CEO of Quanterix. “This test confirms our multi-marker approach as the next phase in the evolution of blood-based testing for AD, and we are excited to present our results at the Clinical Trials on Alzheimer’s Disease (CTAD) conference.”

The test development was funded by the Alzheimer’s Drug Discovery Foundation'sDiagnostics Accelerator.

“Alzheimer’s is a multifaceted disease and as such, we will need a multi biomarker approach to detect the various underlying pathologies. Multiplex platforms, like Quanterix’s Simoa platform, offer the potential to move us closer to a precision medicine approach,” said Howard Fillit, MD, Co-Founder and Chief Science Officer at Alzheimer’s Drug Discovery Foundation. “The ability of LucentAD’s test to reduce the intermediate zone of pTau testing further demonstrates that Alzheimer’s is not a single biomarker disease.”
