The Alzheimer’s Drug Discovery Foundation (ADDF)’s Diagnostics Accelerator (DxA) has invested $1.18 million in the University of Gothenburg to standardize phosphorylated tau 217 (p-tau217) blood tests, a key biomarker for Alzheimer’s disease. Led by Drs. Henrik Zetterberg and Nicholas Ashton, the project aims to develop certified reference materials to ensure consistency across test developers and clinical settings.
“Blood tests are transforming Alzheimer’s diagnosis and treatment,” said Dr. Howard Fillit, ADDF Co-Founder and Chief Science Officer. “Standardization is essential to provide reliable diagnostics globally, enabling patients to access accurate treatments for this debilitating disease.”
Building on successes with cerebrospinal fluid biomarkers like amyloid beta 1-42 (Aβ42) and total tau (t-tau), this initiative seeks to extend these advancements to blood tests, offering a critical step toward widespread diagnostic accessibility. Standardized p-tau217 assays will enhance diagnostic precision and advance research into Alzheimer’s underlying biology and treatment.
“Standardizing p-tau217 is urgently needed for global clinical adoption,” said Dr. Zetterberg. “This DxA investment underscores the importance of evidence-based guidelines in enabling uniform and reliable assays.”
The DxA has invested over $70 million in nearly 70 projects, including initiatives for retinal scans and digital tools, highlighting its commitment to accessible, scalable Alzheimer’s diagnostics. These innovations aim to support early detection, prognostic assessments, and prevention efforts.
As Alzheimer’s research progresses, standardized biomarkers like p-tau217 will be critical for precision medicine approaches, similar to personalized treatments in cancer care. These tools lay the foundation for combination therapies, offering new hope for patients and ensuring continued momentum in Alzheimer’s diagnostics and treatment innovation.
