Package Leaflet: Information for the User
Replagal 1 mg/ml concentrate for solution for infusion
Agalsidase alfa
Read all of this leaflet carefully before you start taking this medicine because it contains important information for you.
Contents of the pack:
The active substance of Replagal is agalsidase alfa (1 mg/ml). Agalsidase alfa is a form of the human enzyme α-galactosidase. It is produced by activating the α-galactosidase A gene in cells. The enzyme is then removed from the cells and converted into a sterile concentrate for solution for infusion.
Replagal is used to treat adult patients, as well as adolescents and children from 7 years of age, with a confirmed diagnosis of Fabry disease. It is used as long-term enzyme replacement therapy when the level of enzymes in the body is absent or lower than normal, as occurs in Fabry disease.
After 6 months of treatment, Replagal significantly reduced pain in patients compared to patients treated with placebo (inactive medicine). Replagal reduced left ventricular mass in treated patients compared to patients treated with placebo. These results suggest that the symptoms of the disease are improving or that the disease is stabilizing.
You should not be given Replagal
Warnings and precautions
Talk to your doctor or pharmacist before you start taking Replagal.
If you notice any of these effects during or after an infusion, you should tell your doctor immediately:
Your doctor may temporarily stop the infusion (5-10 minutes) until the symptoms disappear and then restart the infusion. Your doctor may also treat the symptoms with other medicines (antihistamines or corticosteroids). Most of the time, you can still receive Replagal even if these symptoms occur.
If you have a severe allergic reaction (anaphylactic type), the administration of Replagal will be stopped immediately and your doctor will start appropriate treatment.
If your body produces antibodies due to treatment with Replagal, this will not make Replagal less effective and the antibodies may disappear over time.
If you have advanced kidney disease, you may find that your treatment with Replagal has a limited effect on your kidneys. Talk to your doctor or pharmacist before you start taking Replagal.
Children
Experience in children from 0 to 6 years is limited and, therefore, no dose can be recommended for this age group.
Using Replagal with other medicines
Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.
Tell your doctor if you are taking any medicine that contains chloroquine, amiodarone, benoquin, or gentamicin. There is a theoretical risk of decreased activity of agalsidase alfa.
Pregnancy and breastfeeding
The limited clinical data available on exposure to Replagal during pregnancy do not indicate any adverse effects on the mother or the newborn.
If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.
Driving and using machines
You can drive and use machines while you are receiving Replagal.
This medicine should be administered and supervised by trained personnel who will also calculate the dose to be administered.
The recommended dose is an infusion of 0.2 mg per kilogram of body weight. This corresponds to approximately 14 mg or 4 vials (glass bottles) of Replagal for a person weighing about 70 kg.
Use in children and adolescents
For children and adolescents from 7 to 18 years of age, a dose of 0.2 mg/kg every two weeks may be used.
Children and adolescents may be more likely than adults to experience an infusion-related reaction. Talk to your doctor if you experience any side effects during the infusion.
Method of administration
Replagal must be diluted in a 9 mg/ml sodium chloride solution (0.9%) before administration.
After dilution, Replagal is administered through a vein, usually in the arm.
The infusion will be given every two weeks.
Each time you receive treatment, it will take 40 minutes to administer Replagal through the vein. The treatment will be supervised by a doctor specializing in the treatment of Fabry disease.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
Like all medicines, this medicine can cause side effects, although not everybody gets them.
If you experience a severe allergic reaction (anaphylactic type), the administration of Replagal will be stopped immediately and your doctor will start appropriate treatment.
Most of them are mild or moderate. Approximately 1 in 7 patients (very common reaction) may have a reaction during or after the infusion of Replagal (infusion-related reaction). These reactions include chills, headache, nausea, fever, flushing of the face, fatigue, low blood pressure, instability, sweating, difficulty breathing, itching, tremors, cough, and vomiting. However, some side effects can be serious and may require treatment. Infusion-related reactions that affect the heart, including heart rhythm problems, myocardial ischemia, and heart failure, may occur in patients with Fabry disease that affects the heart (frequency not known). Your doctor may temporarily stop the infusion (5-10 minutes) until the symptoms disappear and then restart the infusion. Your doctor may also treat the symptoms with other medicines (antihistamines or corticosteroids). Most of the time, you can still receive Replagal even if these symptoms occur.
List of other side effects:
Very common: may affect more than 1 in 10 people
Common: may affect up to 1 in 10 people
Uncommon: may affect up to 1 in 100 people
Children and adolescents
The side effects reported in children were, in general, similar to those reported in adults. However, infusion-related reactions (fever, difficulty breathing, chest pain) and worsening of pain occurred more frequently.
