The query: title or abstract mentions "donanemab", "Kisunla" or "LY3002813", matched case-insensitively against each record's title and abstract (its summary field) in alzhub's library of 29,380 study records, as of 2026-11-08. Every count on this page comes from that match. The matched list as JSON.

Donanemab is a monoclonal antibody that targets a modified form of amyloid-beta found in established plaques. It is given by infusion, and in its trials treatment was stopped once a scan showed the plaques had been cleared.

As with lecanemab, the debate in the literature is about the size of the clinical benefit and the rate of ARIA (brain swelling or small bleeds). The counts below show how many papers address each.

This page describes what published research in alzhub's library reports. It is not medical advice and does not apply to any one person: a doctor who knows the person's history is the only one who can say what a result or a treatment means for them.

Questions

What is donanemab?
A monoclonal antibody against a form of amyloid-beta found in plaques, given by intravenous infusion, approved in the United States for early symptomatic Alzheimer's disease with confirmed amyloid. Its brand name is Kisunla.
How is donanemab different from lecanemab?
Both clear amyloid plaques, but they bind different forms of the protein, and donanemab's trials stopped dosing once plaques were cleared on a scan while lecanemab was given continuously. The papers listed below are the place to read how each trial measured its result.
How many studies on donanemab (kisunla) does alzhub hold?
166 of the 29,380 study records in alzhub's library match the query "title or abstract mentions "donanemab", "Kisunla" or "LY3002813""; 62 of them name it in the title. Counted from the records when this page was built.
What kinds of study are they?
18 systematic review or meta-analysis, 1 randomised controlled trial, 22 other clinical trials, 7 cohort or longitudinal studys; 105 record no design.
What is the most recent study in the set?
"When Is Amyloid Really Cleared? Substantial Discordance Between Centiloid Quantitation and Visual Reads of Amyloid PET after Amyloid-Targeting Therapy" (medRxiv, 2026), the newest by publication date among the matched records.
Which journals publish most on it?
Alzheimer's & dementia : the journal of the Alzheimer's Association (7); The journal of prevention of Alzheimer's disease (6); Zenodo (CERN European Organization for Nuclear Research) (6), counted across the matched records.
