1.       What KANUMA is and what it is used for


KANUMA contains the active substance sebelipase alfa. Sebelipase alfa is similar to the naturally occurring enzyme lysosomal acid lipase (LAL), which the body uses to breakdown fats. It is used to treat patients of all ages with lysosomal acid lipase deficiency (LAL deficiency).


LAL deficiency is a genetic disease that leads to liver damage, high blood cholesterol, and other complications due to a build-up of certain types of fats (cholesteryl esters and triglycerides).


How KANUMA works

This medicine is an enzyme replacement therapy. This means that it replaces the missing or defective LAL enzyme in patients with LAL deficiency. This medicine works by lowering the build-up of fat that causes medical complications, including impaired growth, liver damage and heart complications. It also improves blood levels of fats, including elevated LDL (bad cholesterol) and triglycerides.



2.       What you need to know before KANUMA is given


You must not be given KANUMA

  • If you or your child has experienced lifethreatening allergic reactions to sebelipase alfa that cannot be managed when you or your child receives the medicine again, or to egg or any of the other ingredients of this medicine (listed in section 6).


Warnings and precautions

  • If treated with KANUMA, you or your child may experience a side effect while you or your child is being given the medicine or during the hours following the infusion (see section 4). This is known as an infusion reaction which can sometimes be severe, and may include an allergic reaction that could be lifethreatening and require medical treatment. The first time that you or your child are given KANUMA you should be observed by a healthcare professional for 1 hour to watch for any signs of an infusion reaction. If you or your child experiences a severe infusion reaction like this, seek immediate medical attention. If you or your child has an infusion reaction you or your child may be given additional medicines to treat or help prevent future reactions. These medicines may include antihistamines, feverreducing medicines and/or corticosteroids (a type of anti-inflammatory medicines).

If the infusion reaction is severe, your doctor may stop KANUMA infusion and start giving you or your child appropriate medical treatment.

  • The development of blood proteins against KANUMA, also called antidrug antibodies, may occur during the treatment. Talk to your doctor if you experience decreased efficacy with KANUMA
  • This medicine may contain egg proteins. If you or your child has an egg allergy or a history of allergies to eggs, tell your doctor or nurse (see You must not be given KANUMA).


Other medicines and KANUMA

Tell your doctor if you or your child are using, have recently used or might use any other medicines.



There are no data from the use of sebelipase alfa in pregnant women. As a precautionary measure, you should not be given KANUMA if you are pregnant.



It is not known whether sebelipase alfa passes into breast milk. Tell your doctor if you are breast-feeding or plan to do so. Your doctor will then help you decide whether to stop breast-feeding, or whether to stop taking KANUMA, considering the benefit of breast-feeding to the baby and the benefit of KANUMA to the mother.


If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor for advice before taking this medicine.


Driving and using machines

KANUMA may have a minor influence on the ability to drive and use machines. Adverse effects of sebelipase alfa include dizziness which could affect the ability to drive or use machines.


KANUMA contains sodium

This medicine, when diluted with sodium chloride 9 mg/mL (0.9%) solution for infusion for intravenous administration contains 33 mg sodium (main component of cooking/table salt) at the recommended dose. This is equivalent to 1.7% of the recommended maximum daily dietary intake of sodium for an adult. Tell your doctor if you or your child is on a controlled sodium diet.



3.       How KANUMA is given


The dose you or your child receives is based on your or your child’s body weight.


Infants (< 6 months of age)

For patients who have signs and symptoms of the disease when they are infants, the recommended starting dose is 1 mg/kg or 3 mg/kg once weekly. Dose adjustments may be considered based on how well your child responds to treatment.


Children and adults

The recommended dose is 1 mg per kg body weight once every other week through a drip into a vein. Dose adjustments may be considered based on how well the patient responds to treatment.


Each infusion will take approximately 1 to 2 hours. You or your child may be monitored by your doctor or nurse for an additional hour after the infusion. KANUMA should be started at as young an age as possible and is intended for long-term use.


Your doctor or nurse will give KANUMA to you or your child by an infusion (drip) into a vein. The medicine will be diluted before being given to you or your child.
