Aducanumab targets the underlying cause of Alzheimer’s, the most common form of dementia, rather than its symptoms.
Charities have welcomed the news of a new therapy for the condition.
But scientists are divided over its potential impact because of uncertainty over the trial results.
At least 100,000 people in the UK with a mild form of the disease could be suitable for the drug if it were to be approved by the UK regulator.
The US Food and Drug Administration (FDA) said there was “substantial evidence that aducanumab reduces amyloid beta plaques in the brain” and that this “is reasonably likely to predict important benefits to patients”.
Aducanumab targets amyloid, a protein that forms abnormal clumps in the brains of people with Alzheimer’s that can damage cells and trigger dementia, including: memory and thinking problems, communication issues and confusion.
