Analysis has proven that lecanemab slows cognitive decline by a couple of quarter in sufferers within the early phases of Alzheimer’s illness.
Alzheimer’s researchers praised the outcomes of the check as “historic” as a result of no earlier drug had convincingly demonstrated that the underlying mechanism of the illness might be slowed.

Total, it was concluded that the advantages of remedy didn’t outweigh the dangers.
In keeping with Professor Tara Spiers-Jones, chair of the British Neuroscience Affiliation, the EMA’s choice “will likely be a disappointment to many”.
However she mentioned there are causes to stay hopeful.
“Lecanemab has proven that it’s doable to gradual the development of the illness, and analysis is working. Now we have to step up our efforts to find new and safer remedies,” mentioned Prof Spiers-Jones.
In keeping with Prof John Hardy, professor of neuroscience and group chief on the UK Institute for Dementia Analysis at College Faculty London (UCL), the choice may have unintended penalties.
“I am positive we’ll now see rich individuals with early Alzheimer’s flying to the US or different jurisdictions for remedy.”
‘Thrilling second’
The BBC Panorama adopted sufferers on lecanemab and one other new drug: donanemab.
Within the programme, which aired earlier this 12 months, Prof Cath Mummery, neurologist and head of scientific trials at UCL’s Dementia Analysis Centre, mentioned that though the advantages of the medication have been small, they represented a “watershed second”.
She added: “I do not assume they’re false hopes. For the primary time we’ve medication that present you possibly can change the course of Alzheimer’s illness, and that’s one thing extraordinary.”
The Alzheimer’s Society mentioned it revered the choice on the drug however that it will be “very tough information for individuals in Europe who might need been eligible for this drug”.
“Regardless of the regulators resolve, we’re nonetheless at an necessary and thrilling time,” mentioned the affiliation’s Mark MacDonald.
“There are at present 164 energetic scientific trials in Alzheimer’s illness and we anticipate extra remedies to be submitted for approval to the MHRA sooner or later.”
