“This is real progress,” mentioned Joanne Pike of the Alzheimer’s Affiliation. “Having multiple treatment options is the kind of advancement we’ve all been waiting for — all of us who have been touched, even blindsided, by this difficult and devastating disease.”
Like Eisai 4523.T and Biogen’s BIIB.O rival drug Leqembi, which was permitted a yr in the past, donanemab is designed to clear an Alzheimer’s-related protein referred to as beta amyloid from the mind.
A key differentiating issue for donanemab is the drug’s finite dosing, which permits sufferers to cease taking the therapy as soon as mind scans not present amyloid plaques.

“I think that, coupled with the monthly dosing, will make this an attractive option,” he added.
In Lilly’s massive, late-stage trial, donanemab slowed the development of reminiscence and pondering issues by 29% in contrast with a placebo. It additionally brought about mind swelling in almost 1 / 4 of sufferers and mind bleeding in almost a 3rd, however most instances have been gentle.
Because it did for Leqembi, the FDA positioned its strongest “boxed” security warning on donanemab’s prescribing label, flagging the danger of probably harmful mind swelling and bleeding.
One key distinction is that donanemab would require 5 MRI scans to examine for unwanted side effects, whereas Leqembi requires 4, which might be a bonus for the Eisai drug in facilities the place such scans are scarce, RBC Capital analyst Brian Abrahams mentioned in a analysis be aware.
Eisai and Biogen have began submitting information to the FDA to help approval of a month-to-month upkeep dose to be given as an IV infusion, in addition to a weekly injected model of Leqembi that sufferers may obtain at house.
Lilly’s drug is anticipated for use principally by sufferers enrolled within the U.S. authorities’s Medicare well being plan for individuals age 65 and older. Medicare final yr started protecting Alzheimer’s medicine that obtain customary FDA approval.
Morningstar analyst Damien Conover mentioned he expects Lilly’s drug to generate peak annual gross sales of over $5 billion, and “a fairly evenly split market between donanemab and Biogen’s Leqembi.”
