> Novo Nordisk's actual dedicated clinical trials for Alzheimer's completely failed to show that semaglutide stops cognitive decline
Sure, but the EVOKE studies were focused on something that could be sold as a product covered by insurance: semaglutide to those who had already developed Alzheimer’s. It is widely agreed the trial failed because it was a population already diagnosed with dementia. There’s lots of studies not funded by Novo that show semiglutatide has reduced the incidence of dementia in the diabetes population. Novo knows that running a general study on whether semaglutide reduces dementia in a non-diagnosed population is useless to their bottom line because insurance will never pay for everyone to take the drug.
