After weight reduction, Alzheimer’s could also be subsequent frontier for medication like Ozempic

LONDON, Might 8 (Reuters) – Diabetes medication that additionally promote weight reduction reminiscent of Novo Nordisk’s (NOVOb.CO) Ozempic, turning into a darling of celebrities and traders, are being studied to deal with a number of the most difficult-to-treat mind problems, together with Alzheimer’s illness.

Diabetes regimens, from Ozempic to outdated mainstays like insulin and metformin, seem to handle a number of totally different points of the metabolic system implicated in Alzheimer’s illness, together with a protein referred to as amyloid and irritation, researchers say.

The hope is that enhancing glucose utilisation and tamping down irritation in all the physique – together with the mind – may gradual development of debilitating ailments like Alzheimer’s and Parkinson’s.

A number of scientists interviewed by Reuters pointed to mounting research supporting testing diabetes medication towards neurodegenerative ailments.

Outcomes are years away and success unsure. However curiosity has been buoyed by current optimistic information on Alzheimer’s medication developed by Eisai Co Ltd (4523.T) with associate Biogen (BIIB.O) and by Eli Lilly and Co (LLY.N) demonstrating that eradicating sticky amyloid plaques collected within the mind can gradual cognition decline brought on by the deadly mind-wasting illness.

These successes adopted a long time of futility that had left many questioning the validity of the amyloid principle behind most experimental Alzheimer’s medication.

Dr. Suzanne Craft, professor of gerontology and geriatric drugs at Wake Forest College Faculty of Medication, gave a keynote speech at an influential Alzheimer’s scientific assembly late final yr about the necessity to check therapies reminiscent of diabetes medication to additional cut back the advance of Alzheimer’s.

She stated she has since been approached by pharmaceutical firms at an growing tempo, and is at the moment working an Alzheimer’s trial evaluating intranasal insulin together with one other diabetes drug.

Diabetes therapies could amplify the scientific advantage of anti-amyloid medication, and probably result in full stabilization and even some restoration in Alzheimer’s sufferers, Craft stated.

“That is what these brokers do, and what insulin does. It performs a job in regeneration. And that is what must occur. Given its position in modulating immune perform, it could forestall the amyloid from persevering with to build up,” Craft surmised.

In contrast to older off-patent medicines like metformin, there may be business incentive to check newer therapies reminiscent of GLP-1 agonists, a quickly increasing class now dominated by Ozempic, identified chemically as semaglutide, and Lilly’s Mounjaro, with other players working on a dozen potential new therapies.

4 firms with GLP-1 medication, together with two bigger drugmakers, say they’re anticipating outcomes of trials testing Novo’s drug in Alzheimer’s.

Ivan Koychev, marketing consultant neuropsychiatrist for Oxford College Hospitals NHS Basis Belief, is working a trial testing semaglutide with the purpose of halting the earliest adjustments within the brains of individuals susceptible to growing Alzheimer’s.

GLP-1s are his main focus, he stated, as a result of there may be “good epidemiological proof that they’re linked to decrease danger for dementia however run a lot decrease danger of great side-effects relative to the amyloid clearance therapies.”

Anti-amyloid therapies carry the danger of harmful mind swelling.

Any success may result in an enormous payoff. Dementia impacts greater than 55 million folks globally and the marketplace for Alzheimer’s medication is predicted to develop to $9.4 billion by 2028 and for Parkinson’s to $6.6 billion, in line with pharmaceutical information supplier Citeline.

Regardless of their potential towards Alzheimer’s, early analysis has yielded blended outcomes, cautioned Hannah Churchill, analysis communications supervisor on the Alzheimer’s Society.

“It is undoubtedly value pursuing, but it surely’s tough to know whether or not it is a front-runner at this stage,” she stated.


Novo in 2021 started two trials testing semaglutide – additionally bought for weight reduction as Wegovy – in hundreds of sufferers with early Alzheimer’s. Outcomes are anticipated by 2025 because it takes years to point out an impact on the progressive situation.

The Danish drugmaker declined to be interviewed for this story.

“Everyone seems to be ready to see what that may present. Traders need any person else to first take the danger in Alzheimer’s, like Novo,” stated Ted Dawson, professor of neurology at John Hopkins College and co-founder of Neuraly, which has an experimental GLP-1 drug.

Lilly informed Reuters it’s watching that trial intently. Pfizer (PFE.N)which has experimental GLP-1s, additionally has its eye on Novo.

Smaller firms, together with U.S.-based Neuraly and Denmark-based Kariya Prescribed drugs, stated they’re evaluating experimental GLP-1 medication towards Parkinson’s and will contemplate transferring onto Alzheimer’s ought to the Novo trial bear fruit.

Parkinson’s trials are inclined to take much less time and should require fewer sufferers as a result of it is simpler to evaluate the influence on motor perform traits of the illness to know whether or not the therapies profit the mind.

Wassilios Meissner, head of the division of neurology for neurodegenerative ailments at College Hospital Bordeaux, is concerned in a mid-stage Parkinson’s trial testing Sanofi’s (SASY.PA) GLP-1 lixisenatide.

Meissner stated postmortem analysis of the brains of each Alzheimer’s and Parkinson’s sufferers exhibits insulin signalling is impaired.

“That signifies that these pathways that present help to the mind are dysfunctional,” he stated. “So folks have began questioning whether or not there is likely to be an curiosity for anti-diabetics for the remedy of those problems.”
