Throughout a day-long dialogue, committee members famous that, if permitted, donanemab would have some obvious benefits over Leqembi. The older drug is given each two weeks indefinitely, whereas the newer one is given month-to-month and could possibly be stopped for some sufferers.

The committee mentioned the dangers related to donanemab at size.
Members have been particularly involved about individuals who carry two copies of a gene known as APOE4. The gene vastly will increase the danger that they’ll get Alzheimer’s, however it additionally vastly will increase the danger of mind bleeding or swelling after they obtain donanemab.
However Colette Johnston, the affected person consultant on the committee, mentioned even higher-risk sufferers ought to have entry to the drug.
