Donanemab
Brand name: Kisunla (kih-SUHN-lah)
Dosage form: injection for intravenous use (350 mg/20 mL)
Drug class: Miscellaneous central nervous system agents
What is donanemab?
Donanemab (Kisunla) is used to Alzheimer’s disease to help slow down the decline in memory, thinking, and daily functioning. This means that Alzheimer’s disease does not progress as quickly, and people can continue living their lives doing their daily activities and hobbies for a longer time.
Alzheimer's disease symptoms are thought to be related to clumps of amyloid protein (amyloid plaques) that can occur in the brain. Donanemab is an amyloid plaque-targeting therapy that works by helping the body remove amyloid plaques in the brain, which slows the progression of Alzheimer’s disease.
Donanemab is administered as a once-monthly IV infusion that takes approximately 30 minutes. The dose is increased slowly over the first 4 infusions to reduce the risk of side effects.
Donanemab (Kisunla) FDA approval was received on July 2, 2024, as a treatment for adults with early symptomatic Alzheimer's disease (AD), which includes people with mild cognitive impairment (MCI) as well as people with mild dementia stage of AD, with confirmed amyloid pathology. Kisunla (donanemab) is an Eli Lilly and Company product.
How well does it work?
Kisunla (donanemab) significantly slowed Alzheimer's disease progression by more than 20% at 76 weeks in the TRAILBLAZER-ALZ 2 clinical trial. This was measured using the Integrated Alzheimer’s Disease Rating Scale (iADRS) and Clinical Dementia Rating Scale Sum of Boxes (CDR-SB) score in patients with low/medium tau and in the combined low/medium and high tau populations.
Treatment with Kisunla benefited all groups of trial participants, but patients in earlier stages of the disease showed the most significant improvements.
Donanemab side effects
Common donanemab side effects
Common Kisunla side effects include headache and swelling in areas of the brain with or without small spots of bleeding in or on the brain's surface. These occurred in at least 10% of patients and at a higher incidence compared to placebo.
Serious donanemab side effects
- Serious allergic reactions include swelling of the face, lips, mouth, or eyelids, difficulty breathing, and hives. Tell your healthcare provider if you have any symptoms of a serious allergic reaction during or after your infusion.
- Infusion-related reactions. If you have an infusion-related reaction, your infusion may be slowed down or stopped. Tell your healthcare provider right away if you have symptoms of sweating, irritation of the skin, headache, nausea, chest pain, vomiting, or problems breathing during an infusion chills. If you have had an infusion-related reaction while receiving donanemab, your healthcare provider may give you an antihistamine, acetaminophen, or a steroid before your infusions to decrease your risk of having an infusion reaction.
This is not a complete list of side effects, and others may occur. Call your doctor for medical advice about side effects. You may report side effects to the FDA at 1-800-FDA-1088.

Warnings
Donanemab can cause serious side effects, including:
Amyloid-Related Imaging Abnormalities or ARIA.
ARIA is a common side effect that does not usually cause any symptoms, but sometimes serious symptoms can occur. ARIA can be fatal. It is most commonly seen in an MRI as temporary swelling in areas of the brain that usually resolves over time. Some people may also have small spots of bleeding in or on the surface of the brain, and infrequently, larger areas of bleeding in the brain can occur.
Most people who develop ARIA do not have symptoms; however, some people may have symptoms such as headache, dizziness, nausea, difficulty walking, confusion, vision changes, and seizures.
If you have any of the symptoms of ARIA listed above, you should call your healthcare provider or go to the nearest hospital emergency room right away.
You are more at risk of ARIA if you have a genetic risk factor (homozygous apolipoprotein E ε4 gene carriers). Your healthcare provider may test to see if you have this risk factor.
If you take medicines to reduce blood clots from forming (antithrombotic medicines) while receiving donanemab, you may be at a higher risk of developing bleeding in the brain.
Magnetic resonance imaging (MRI) scans are done before and during your treatment to check you for ARIA.
You should carry information that you are receiving donanemab, which can cause ARIA, and that ARIA symptoms can look like stroke symptoms.
There are registries that collect information on treatments for Alzheimer’s disease. Your healthcare provider can help you become enrolled in these registries.
Consider the risk of ARIA and the benefit of Alzheimer's disease when deciding to treat with donanemab.
Who should not take donanemab?
