EU approves sale of new Alzheimer’s drug, with conditions
BRUSSELS: The European Commission said Wednesday that it had given formal approval for Leqembi, a long-awaited new treatment for early-stage Alzheimer’s disease, to be sold in the EU under strict conditions.
The authorisation was granted Tuesday based on a favourable decision by Europe’s medicines watchdog, which after initial misgivings endorsed the treatment last November for a set category of patients.
Leqembi, developed by US multinational Biogen and Japanese-based Eisai, is the brand name of an active substance called lecanemab that is used to treat adults with mild memory and cognitive problems resulting from the early stages of the common type of dementia.
The first such medicine to be allowed in the EU, the drug was approved in line with the “positive scientific assessment of the European Medicines Agency,” the commission said in a statement.
The EMA “concluded that the benefits of this medicine outweighed the risks, in a particular population of patients with such disease and as long as risk minimisation measures are applied,” the commission said.
“Therefore, the authorisation decision also sets strict conditions on the use of Leqembi, as well as clear risk mitigation requirements,” it said.
The EMA endorsed the drug only for patients with a lower risk of potential brain bleeding: those who have “only one copy or no copy of ApoE4”, a type of gene known as an important risk factor for Alzheimer’s.
Lecanemab has been hailed by Alzheimer’s researchers and charities for being the first approved treatment that tackles the early stages of the disease, rather than managing the symptoms.
It works by using antibodies that bind to and clear the proteins that normally build up in the brains of people with Alzheimer’s, the most common type of dementia.
The treatment has been shown to decrease cognitive decline by a quarter in people in the early stages of the disease.
Leqembi, together with another Alzheimer’s drug called Aduhelm, received approval from the US Food and Drug Administration in 2023.
