- The Elecsys® pTau217 plasma biomarker test is being developed as part of an ongoing partnership between Roche and Eli Lilly and Company
- Once approved, the test will aid healthcare providers in identifying amyloid pathology, a key feature of Alzheimer’s disease
- Roche and Lilly believe the test could play an important role in improving access to early and accurate Alzheimer’s diagnosis
The incidence of dementia is growing worldwide, with 75% of cases remaining undiagnosed.1 Consequently, there is a critical role for Diagnostics to play in addressing this global health challenge,” said Matt Sause, CEO of Roche Diagnostics. “We believe pTau217 is going to be crucial in the diagnosis of Alzheimer’s disease, a condition for which Roche Diagnostics is committed to improving the lives of patients worldwide. We plan to leverage our installed base of diagnostic systems, which is the largest in the world, to ensure we are able to create access to this test for those who need it the most.
“The development of the Elecsys pTau217 plasma assay is another milestone in our collaboration with Roche Diagnostics that will advance the Alzheimer’s diagnostic ecosystem,” said Anne White, executive vice president of Eli Lilly and Company and president of Lilly Neuroscience. “We’re excited to help meet the growing need for additional diagnostic tools to enable a timely and accurate diagnosis for people with Alzheimer’s disease.”
pTau217, which is a phosphorylated fragment of the protein tau, is a biomarker that has shown the ability in research settings to distinguish Alzheimer’s disease from other neurodegenerative disorders and has shown strong performance relative to other biomarkers.2
As global leaders in Alzheimer’s innovation, Roche and Lilly hope that this collaboration can bring additional speed and scale to testing and diagnosis in this important area of unmet medical need.
About Elecsys pTau217
Elecsys Phospho-Tau (217P) is intended to be an in-vitro diagnostic immunoassay for the quantitative determination of the protein Phospho-Tau (217P) (pTau217) in human plasma from individuals aged 60 years and older. The test is intended for use as an aid in identifying amyloid pathology, a pathological feature of Alzheimer’s disease.
A positive Elecsys pTau217 result indicates a high likelihood of having a positive amyloid PET/cerebrospinal fluid (CSF) result.
A negative Elecsys pTau217 result indicates a high likelihood of having a negative amyloid PET/CSF result.
An indeterminate pTau217 result indicates uncertainty on the amyloid PET/CSF result.
The pTau217 result should be used in the diagnostic pathway in conjunction with other clinical information.
About Roche in Alzheimer’s disease
With more than two decades of scientific research in Alzheimer’s, Roche is working toward a day when we can detect the disease early and stop its progression to preserve what makes people who they are. Today, the company’s Alzheimer’s portfolio spans investigational medicines for different targets, types and stages of the disease. This includes trontinemab, an innovative Brainshuttle™ anti-amyloid treatment that is specifically engineered to cross the blood-brain barrier. On the diagnostics side, it also includes approved and investigational tools, including digital and blood-based tests and CSF assays, aiming to more effectively detect, diagnose and monitor the disease. Yet the global challenges of Alzheimer’s go well beyond the capabilities of science, and making a meaningful impact requires collaboration both within the Alzheimer’s community and outside of healthcare. We will continue to work together with numerous partners with the hope we can transform millions of lives.
About Breakthrough Device Designation
The Breakthrough Devices Program is a voluntary program for certain medical devices that provide for more effective treatment or diagnosis of a life-threatening or irreversibly debilitating disease or condition. This program is designed to expedite the development and review of these medical devices.
