1. What is Elaprase and what is it used for
Elaprase is used as enzyme replacement therapy to treat children and adults with Hunter syndrome (Mucopolysaccharidosis II) when the level of the enzyme iduronate-2-sulfatase in the body is lower than normal, helping to improve the symptoms of the disease. When you have Hunter syndrome, a carbohydrate called glycosaminoglycan, which is normally metabolized by the body, is not metabolized and slowly accumulates in various cells of the body. This causes abnormal functioning of these cells, and consequently causes problems in several organs that can lead to tissue destruction and organ dysfunction and failure. The typical organs where glycosaminoglycan accumulates are the spleen, liver, lungs, heart, and connective tissue. In some patients, glycosaminoglycan also accumulates in the brain. Elaprase contains an active substance called idursulfase, which acts as a replacement for the enzyme that is at a low level, and thus breaks down this carbohydrate in the affected cells.
Enzyme replacement therapy is usually given as long-term treatment.
2. What you need to know before you use Elaprase
Do not use Elaprase
- if you have had severe or life-threatening allergic reactions to idursulfase or any of the other ingredients of this medicine (listed in section 6) that could not be controlled with medical treatment.
Warnings and precautions
Talk to your doctor or nurse before you start using this medicine.
If you are being treated with Elaprase, you may experience side effects during or after the infusion (see section 4, Possible side effects). The most common symptoms are itching, rash, hives, fever, headache, increased blood pressure, and flushing of the face. In most cases, this medicine can still be given to you even if these symptoms occur. If you experience an allergic reaction after receiving this medicine, you should contact your doctor immediately. You may be given other medicines, such as antihistamines and corticosteroids, to treat or help prevent allergic reactions.
Your doctor will stop the infusion immediately if severe allergic reactions occur and will start the appropriate treatment. You may need to stay in the hospital.
The nature of your genotype (a genetic makeup of all active genes in human cells, which determines individual characteristics and specific features of each person) may influence your therapeutic response to this medicine, as well as your risk of developing antibodies and experiencing infusion-related side effects. In individual cases, so-called "neutralizing antibodies" may develop, which may decrease the activity of Elaprase and your response to treatment. The long-term effects of antibody development on treatment response have not been established. Talk to your doctor for more information.
