First Approved Blood Test Predicts Likely Progression to Alzheimer's Up to Six Years in Advance

The first approved blood test can identify whether individuals with early cognitive impairment will or will not progress to Alzheimer's disease with high accuracy.

Diadem Srl (Brescia, Italy) has received CE IVD certification for its AlzoSure Predict prognostic blood test for the early prediction of Alzheimer's disease, allowing . the company to take the test to markets in the UK and the 27 countries of the European Union (EU). It also enables market development across much of the rest of the world. The accreditation follows the US Food and Drug Administration's awarding of a Breakthrough Device Designation to AlzoSure Predict in January.

AlzoSure Predict is a biomarker blood test that can identify with high accuracy whether individuals over the age of 50 with signs of cognitive impairment will or will not progress to Alzheimer's disease up to six years before definitive symptoms are apparent. The company's technology uses an analytical method that includes a proprietary and patented antibody developed by Diadem designed to bind to U-p53AZ and its target sequences. U-p53AZ is a conformational variant of the p53 protein that has been implicated in the pathogenesis of AD in multiple studies.

AlzoSure Predict's accreditation is supported by positive clinical data from a 482-patient longitudinal study showing that the test can identify whether individuals will or will not progress to full-fledged Alzheimer's disease up to six years before the illness is apparent. Patients were aged 50 years or older at the start of the study and asymptomatic or at the early stages of AD or other dementias. The second phase of this study, which includes biobank data on more than 1,000 additional patients from Europe and the US, will be completed in the coming months.

"This first regulatory approval for AlzoSure Predict is a signal event for our scientists whose insight and commitment have enabled us to achieve this milestone," said Paul Kinnon, CEO of Diadem. "We believe it represents a significant advance for the millions of patients and their families in Europe at risk from Alzheimer's disease. Earlier knowledge will benefit those who are found to be not likely to advance to AD as well as those individuals found to be at risk, who can now take steps to slow the progression of the condition. We will be partnering with a variety of health providers to ensure wide access to AlzoSure Predict and expect the test to be available to physicians and patients in the EU in the coming months."
