US approves first new Alzheimer’s drug in 20 years
Islam News – 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 Alzheimer 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”.
Controversial trial
In March 2019, late-stage international trials of aducanumab, involving about 3,000 patients, were halted when analysis showed the drug, given as a monthly infusion, was not better at slowing the deterioration of memory and thinking problems than a dummy drug.
But later that year, the US manufacturer Biogen analysed more data and concluded the drug did work, as long as it was given in higher doses. The company also said it significantly slowed cognitive decline.
Aldo Ceresa, who took part in the trial, first noticed problems differentiating between left and right 10 years ago.
After his diagnosis, the 68-year-old, who is originally from Glasgow and now lives in Oxfordshire, close to his family, had to give up his job as a surgeon.
Mr Ceresa took aducanumab for two years before the trial was halted – and then had to wait almost as long for another trial, at the National Hospital for Neurology and Neurosurgery, in London, to begin.
“I’m quite happy to volunteer,” he says.
“I really, really enjoy this journey that I’m going through – and obviously the benefits I’m getting from it, which I’m very, very grateful for.”
He is convinced the drug has helped him.
“I feel like I’m not quite as confused. Although it’s still there, it’s not quite as bad. And I’m just getting that bit more confident now.”
Mr Ceresa says his family has noticed improvements too.
More than 30 million people around the world are thought to have Alzheimer’s, with most aged over 65.
For around 500,000 people affected in the UK, those eligible for aducanumab will be mostly in their 60s or 70s and at an early stage of the disease.
We need to keep our feet on the ground.
This is not a miracle drug, nor a cure for Alzheimer’s but it is the first treatment which tackles the destructive mechanism in the brain that drives the destruction of neurons. And that makes this a landmark moment.
‘Grave error’
And Prof Robert Howard, professor of old age psychiatry at UCL, went further calling the drug’s approval “a grave error” that could derail the ongoing search for meaningful dementia treatments “for a decade”.
He said the FDA had ignored data from the trial which showed no slowing of decline in cognition or function.
However, Alzheimer’s Society said the drug was “promising” but added it was “just the beginning of the road to new treatments for Alzheimer’s disease”.
Another charity, Alzheimer’s Research UK, said it had written to the Health Secretary Matt Hancock asking the government to prioritise the fast-track approval process for the drug in the UK.
Chief executive Hilary Evans, said: “People with dementia and their families have been waiting far too long for life-changing new treatments.
“It is now essential that regulatory authorities assess the evidence to decide whether they believe the drug is safe and effective for use in the UK.”
Although many doctors are doubtful of aducanumab’s benefits, its US approval could be a huge boost to dementia research, which is traditionally underfunded compared with cancer or heart disease.
