How Kisunla (donanemab) works

Kisunla (donanemab) is a type of monoclonal antibody. It attaches to proteins in the brain called amyloid beta (or beta-amyloid). In Alzheimer's disease, these proteins clump together. This forms plaques that can be harmful to your brain cells.

Kisunla (donanemab) works to lessen plaque buildup in the brain. This might help slow Alzheimer's from getting worse.

Pharmacist tips for Kisunla (donanemab)

pharmacist
  • Each Kisunla (donanemab) infusion is given every 4 weeks. Mark your infusion dates on your calendar to help you stay on track with your treatment.
  • If you miss a Kisunla (donanemab) infusion, call your care team to reschedule it as soon as possible.
  • Your prescriber will order MRI scans before starting Kisunla (donanemab). You'll also need an MRI before your 2nd, 3rd, 4th, and 7th infusions. These are important to make sure the medication isn't causing serious problems like bleeding or swelling in your brain.
  • During your Kisunla (donanemab) infusion, let a member of your care team know if you don't feel well. Tell them if you have any trouble breathing, chills, chest pain, or nausea. These could be signs of an infusion-related reaction. Your nurse might slow down the infusion and give you medications to help you feel better. Also tell them if these symptoms happen a few hours after you leave the infusion center.
  • If you've had a reaction to an infusion, your care team have you take some medications before your next Kisunla (donanemab) infusions. These medications can help prevent another reaction or make it less severe. They can include an antihistamine, acetaminophen (Tylenol), or a steroid.
  • Let your prescriber know if you take medications that help lower the risk of blood clots. This includes aspirin and blood thinners. Your prescriber will talk to you about your risk of possible bleeding problems with Kisunla (donanemab) treatment.
  • You're encouraged to join research programs that help experts learn more about Alzheimer's disease. They also help explore more about how treatments can make a difference. For more information, ask your prescriber or call 1-800-545-5979.

Common questions about Kisunla (donanemab)

Each infusion of Kisunla (donanemab) takes about 30 minutes. But if you have a reaction to the infusion, your care team might slow it down. This can make the infusion take longer. Also remember to account for time to settle down before your infusion too. Plan accordingly, and bring a book to read or music to listen to during your infusion to help pass the time.

No, Kisunla (donanemab) doesn't cure Alzheimer's disease (AD). But it can help slow it down. In studies, people with early AD who took Kisunla (donanemab) did better on Alzheimer's tests after about a year and half of treatment than those who took a placebo (no active medication).

There isn't a set number of Kisunla (donanemab) infusions that you should get. There also isn't a specific length of time you should take the medication. In general, you get your Kisunla (donanemab) infusion once every 4 weeks. During treatment, your prescriber will check for amyloid plaques in your brain. They might decide to stop the medication if your brain scan shows that the plaque levels are low enough. Talk to your prescriber about how long you should take Kisunla (donanemab).

Kisunla (donanemab) is made by Eli Lilly and Company.

Kisunla (donanemab) and Leqembi (lecanemab) are both used to treat mild Alzheimer's disease. They're both infusions given through the vein by a healthcare professional. But how long the infusions take and how often you need them are different. Kisunla is a 30-minute infusion that's given once every 4 weeks. But the Leqembi infusion takes 1 hour and is given either every 2 or 4 weeks. Also, the IV dose for Leqembi is based on body weight. But the Kisunla dose is fixed and is slowly raised over the first 4 infusions to lower the risk of serious side effects. In addition, after a year and a half of treatment with Leqembi, there's an option to switch to Leqembi Iqlik. This is a new version of Leqembi that's given as an injection under the skin once weekly at home. Kisunla doesn't have this option yet. Talk to your Alzheimer's specialist about the similarities and differences between Kisunla and Leqembi.

Risks and warnings for Kisunla (donanemab)

Kisunla (donanemab) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.

Amyloid related imaging abnormalities (ARIA)

  • Risk factors: Having two copies of the apolipoprotein E ε4 (ApoE ε4) gene | Taking medications that can raise bleeding risk

Kisunla (donanemab) can cause a side effect called amyloid related imaging abnormalities (ARIA). They're usually found on MRI scans and look like swelling or bleeding in the brain.

Check with your prescriber about the benefits of Kisunla (donanemab) and the risk of ARIA. ARIA can happen to anyone with Alzheimer's disease. But the risk seems higher for those with the ApoE ε4 gene. Also tell your prescriber about all the other medications you take or plan to take. Medications like aspirin or other blood thinners such as clopidogrel (Plavix) might raise your risk of bleeding in the brain.

ARIA most commonly happens early in treatment (within the first 24 weeks, or 6 months). But it's important to note that it can happen at anytime. It can also happen more than one time during treatment.

Most people don't notice any symptoms from ARIA. That's why you'll need an MRI before and periodically during treatment to watch out for it. If you do have symptoms, they usually go away over time. But some can be more serious and life-threatening. Call your care team right away if you have a headache, vision changes, confusion, dizziness, nausea, trouble walking, or a seizure.

Infusion-related reactions

Some people can have a reaction to the Kisunla (donanemab) infusion itself. These reactions usually happen during the infusion or within 30 minutes after, but they can also occur hours after. They happen most often within the first 4 infusions, especially with the first one.

Infusion-related reactions can include chills, headache, flushing, sweating, and chest pain. Some people might also feel nauseous, vomit, have trouble breathing, or have changes in blood pressure. Most reactions are mild or moderate in severity, but some can be serious.

Tell the nurse if you don't feel well, have trouble breathing, or have chest pain during or after your Kisunla (donanemab) infusion. The nurse can slow down the infusion or stop it completely. They can give you supportive care to help with symptoms if needed. Your prescriber might give you medications for you to take before your next infusion. This can help lower your chance of having another reaction.

Allergic reactions

Some people have had very serious allergic reactions to Kisunla (donanemab). They can include severe swelling, trouble breathing, and anaphylaxis. Get medical help right away if you notice hives, swelling in your face or throat, or trouble breathing.
