March 15, 2021 — An experimental drug appeared to sluggish cognitive decline in individuals with early Alzheimer’s illness, in line with newly revealed analysis.
The drug, donanemab, is an antibody that targets and removes plaques from the brain referred to as amyloid-beta, that are thought to play a job in Alzheimer’s illness.
Compared to individuals in the examine who acquired a placebo, individuals who obtained donanemab confirmed 32% slower cognitive decline over a 12 months and a half, in line with examine outcomes published in the New England Journal of Medicine and introduced on the 2021 International Conference on Alzheimer’s and Parkinson’s Diseases. People who obtained the experimental drug additionally had a higher discount in the quantity of amyloid plaques in the mind, in comparison with individuals who obtained the placebo.
The outcomes from the comparatively small, early examine give “a sign … that there may be a modest cognitive profit,” mentioned Howard Fillit, MD, neuroscientist and chief science officer of the Alzheimer’s Drug Discovery Foundation, who was not concerned with the analysis.

Though the examine measured a slower fee of cognitive decline for individuals who took the experimental drug, it’s not clear but whether or not this slowdown makes a noticeable distinction for individuals with Alzheimer’s, he mentioned, significantly contemplating that researchers didn’t see the identical profit after they assessed trial members with further measures of cognitive capability.
“Basically, it was a optimistic examine that most likely must be adopted by one other, a lot bigger examine to get us to essentially see the profit,” Fillit mentioned.
The trial was carried out at 56 websites in the United States and Canada and included 257 sufferers between the ages of 60 and 85. The drug firm growing donanemab, Eli Lilly, funded the examine.
The researchers observe that further trials following extra sufferers for longer intervals of time are warranted to additional decide the efficacy and security of donanemab in Alzheimer’s illness.
In a press release, Maria Carrillo, PhD, chief science officer for the Alzheimer’s Association, mentioned the group “is inspired by this promising information,” whereas calling for extra work to evaluate the experimental drug.
“I’m eager for the long run,” Carrillo mentioned.
