Swiss drugmaker Roche has received the CE mark – a European ​regulatory clearance allowing sale in the ‌region – for its second Elecsys blood test for Alzheimer’s disease, it said on Tuesday.

 

The ​test was developed with U.S. company ​Eli Lilly (LLY.N).

Compared with its already approved pTau181 ⁠test, which mainly helps rule out ​Alzheimer’s-related amyloid pathology, the newer pTau217 test ​can both help confirm and exclude the disease. It is validated for use in both ​primary and specialist care.

The test has ​already received breakthrough device designation from the U.S. ‌FDA.

Blood ⁠tests could speed diagnosis and widen access to treatments such as Biogen (BIIB.O) and Eisai’s (4523.T) Leqembi and Eli Lilly’s Kisunla, ​as current ​diagnostic methods ⁠are often costly or uncomfortable.

Roche said an estimated 75% ​of people living with dementia remain ​undiagnosed.

The ⁠test is expected to become available in CE-marked markets from July, Olivier Gillieron, life ⁠cycle ​leader in cardiometabolic and ​neurology at Roche told media in a call.
