Roche has announced that its blood test, Elecsys pTau217, has been granted breakthrough device designation from the US Food and Drug Administration for earlier diagnosis of Alzheimer’s disease (AD).

The blood test, which is being developed in collaboration with Eli Lilly, works to identify the presence or absence of amyloid pathology in individuals, a pathological feature of the neurodegenerative condition.

AD is a progressive form of dementia that slowly destroys an individual’s memory and thinking skills.

According to the Alzheimer’s Society, around 55 million people are living with dementia globally, which is estimated to rise to 139 million by 2050.

In previous studies, pTau217 has shown the ability to distinguish AD from other neurodegenerative disorders and has demonstrated a strong performance relative to other biomarkers.

To be used in the diagnostic pathway with other clinical information, a positive result of the Elecsys pTau217 test indicates a high likelihood of having a positive amyloid positron emission tomography (PET)/cerebrospinal fluid (CSF) result.

Both companies believe that the plasma biomarker test could play a significant role in improving access to early and accurate AD diagnosis, following approval.

If successful, the test will support healthcare providers in identifying amyloid pathology in individuals and help ensure that they are able to receive the appropriate care, including through participating in clinical trials or by gaining access to approved disease-modifying therapies.

There is a critical role for diagnostics to play in addressing this global health challenge,” said Matt Sause, chief executive officer of Roche Diagnostics.

We believe pTau217 is going to be crucial in the diagnosis of AD… [and] we plan to leverage our installed base of diagnostic systems… to ensure we are able to create access to this test for those who need it the most,” Sause added.

Anne White, executive vice president of Eli Lilly and president of Lilly Neuroscience, said: “We’re excited to help meet the growing need for additional diagnostic tools to enable a timely and accurate diagnosis for people with AD.”

announced its partnership with Eli Lilly in March 2023 to develop the blood test for AD to help streamline the journey to diagnosis for more patients.
