Evidence suggests that people get the most benefit if they are given the treatment earlier in the disease. Treatment with donanemab reduced amyloid plaque on average by 84% at 18 months, Lilly found.
Donanemab, sold under the brand name Kisunla, is a monoclonal antibody used for the treatment of Alzheimer's disease. [1] [2] Donanemab was developed by Eli Lilly and Company. [3] [4] The most common side effects include amyloid-related imaging abnormalities and headache. [2] Donanemab was approved for medical use in the United States in July 2024.
Aducanumab, sold under the brand name Aduhelm, is a monoclonal antibody designed to treat Alzheimer's disease. It is a monoclonal antibody that targets aggregated forms (plaque) of amyloid beta (Aβ) found in the brains of people with Alzheimer's disease to reduce its buildup. [10] It was developed by Biogen and Eisai. [11] Aducanumab is given via intravenous infusion. [5] Aducanumab was ...
In Lilly's large clinical trial, donanemab, given by infusion once a month, slowed progression of memory and thinking problems by 29% overall, roughly comparable to the 27% slowing seen with Leqembi.
The FDA was initially set to decide about the treatment in March but delayed the decision in order to get more guidance from its advisory panel on whether the benefits outweighed the side effects.
The blood–brain barrier is formed by special tight junctions between endothelial cells lining brain blood vessels. Blood vessels of all tissues contain this monolayer of endothelial cells, however only brain endothelial cells have tight junctions preventing passive diffusion of most substances into the brain tissue.

Human monoclonal antibodies (suffix -umab) are produced using transgenic mice or phage display libraries by transferring human immunoglobulin genes into the murine genome and vaccinating the transgenic mouse against the desired antigen, leading to the production of appropriate monoclonal antibodies.
