Risk of amyloid-related imaging abnormalities

Kisunla has a boxed warning for the risk of amyloid-related imaging abnormalities (ARIA). A boxed warning is the most serious warning from the FDA. It alerts people about certain drug effects that may be dangerous.

In studies of Kisunla, ARIA was a common side effect. This refers to abnormalities that may appear on imaging such as MRI scans. They typically occur when your first begin treatment, but it can happen anytime during treatment.

ARIA can appear as either swelling or bleeding spots in different parts of your brain. In some cases, large bleeding areas of your brain may occur.

ARIA usually doesn’t cause any symptoms. However, some people have symptoms such as:

• headache
• confusion
• dizziness
• vision changes
• nausea
• seizures
• difficulty walking

In rare cases, ARIA can cause serious complications including seizures and status epilepticus.

Having a certain genetic risk factor (homozygous apolipoprotein E ε4 gene carrier) can raise the risk of developing ARIA if you receive Kisunla.

Taking antithrombotic medications, which help prevent and treat blood clots, can raise your risk of bleeding in your brain. Brain bleeding can also occur with certain types of ARIA. So, you may be more likely to experience ARIA with brain bleeding if you take antithrombotic medications during your Kisunla treatment.

What might help

Before receiving Kisunla, talk with your doctor about your medical conditions and all medications your take, including prescriptions, supplements, and over-the-counter medications. Your doctor will help determine whether Kisunla is the right medication for you.

Your doctor will likely order a test to check for the genetic factor mentioned above before prescribing Kisunla for you. Before and during your Kisunla treatment, your doctor will also order MRI scans of your brain. This will help check for brain abnormalities or changes. Your doctor will monitor you more closely during the first 24 weeks of treatment for any brain changes.

It may be difficult to distinguish ARIA symptoms from symptoms of a stroke. If you develop symptoms of ARIA described above, immediately call your doctor or go to the closest emergency room.

Infusion reactions

Severe infusion reactions were an uncommon side effect in studies of Kisunla. Mild and moderate infusion reactions were more commonly reported.

Infusion reactions typically occur during the infusion or within 30 minutes after the infusion ends. An infusion reaction may not occur with each dose of Kisunla. The majority of infusion reactions were reported within the first four doses.

Infusion-related reactions may cause symptoms such as:

• chills
• nausea and vomiting
• sweating
• headache
• chest pain
• trouble breathing
• skin irritation

What might help

Your doctor may give you other medications before your Kisunla infusion. This is to help prevent infusion-related reactions. They may give you the following medications:

• antihistamine, such as diphenhydramine (Benadryl)
• pain reliever, such as acetaminophen (Tylenol)
• corticosteroid, such as prednisone (Rayos)

If you develop infusion-related reaction during or after your Kisunla treatment, talk with your doctor right away. They may slow or stop the infusion if you’re receiving a dose at the time. Or they may consider an alternative treatment in the future.

Keeping track of side effects

During your Kisunla treatment, consider taking notes on any side effects you’re having. You can then share this information with your doctor. This is especially helpful when you first start taking a new drug or receiving a combination of treatments.

Your side effect notes can include things such as:

• what dose of the drug you were taking when you had the side effect
• how soon you had the side effect after starting that dose
• what your symptoms were
• how your symptoms affected your daily activities
• what other medications you were taking
• any other information you feel is important

Sharing notes with your doctor will help them learn more about how Kisunla affects you. They can then use this information to adjust your treatment plan if needed.
