The active substance in Replagal is agalsidase alfa (1mg/ml). Agalsidase alfa is a form of the human enzyme α-galactosidase. It is produced by switching on the gene for α-galactosidase A in cells. The enzyme is then removed from the cells and made into a sterile concentrate for solution for infusion.
Replagal is used to treat adult patients, as well as adolescents and children from the age of 7, with confirmed diagnosis of Fabry Disease. It is used as long-term enzyme replacement therapy when the level of enzyme in the body is absent or lower than normal as in Fabry Disease.
After 6 months of therapy Replagal significantly reduced pain in patients when compared to placebo (dummy) treated patients. Replagal reduced left ventricle mass in treated patients compared to placebo treated patients. These results suggest the symptoms of the disease are improving or the disease is becoming stable.
- if you are allergic to agalsidase alfa or any of the other ingredients of this medicine (listed in section 6).
Talk to your doctor or pharmacist before Replagal is used.
If you notice any of these effects during or after an infusion you should tell your doctor immediately:
- high fever, chills, sweating, fast heart rate.
- vomiting.
- light-headedness.
- hives.
- swelling in your hands, feet, ankles, face, lips, mouth or throat which may cause difficulty in swallowing or breathing.
Your doctor may stop the infusion temporarily (5-10 min) until the symptoms go away and then begin the infusion again.
Your doctor may also treat the symptoms with other medicines (antihistamines or corticosteroids).
Most of the time you can still be given Replagal even if these symptoms occur.
If you experience a severe allergic (anaphylactic-type) reaction, the administration of Replagal will be immediately discontinued and an appropriate treatment will have to be initiated by your doctor.
If treatment with Replagal makes your body produce antibodies this will not stop Replagal from working and the antibodies may disappear with time.
If you have advanced renal disease, you may find that your Replagal treatment has a limited effect on your kidneys. Talk to your doctor or pharmacist before using Replagal.
The experience in children 0-6 years old is limited and therefore no dose can be recommended for this age group.
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.
Tell your doctor if you use any medicines containing chloroquine, amiodarone, benoquin or gentamicin. There is a theoretical risk of decreased agalsidase alfa activity.
Very limited clinical data on pregnancies exposed to Replagal have shown no adverse effects on the mother and newborn child.
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.
You may drive and use machines whilst on Replagal.
This medicine contains 14.2 mg sodium (main component of cooking/table salt) in each vial. This is equivalent to 0.7 % of the recommended maximum daily dietary intake of sodium for an adult.
This medicine contains 0.836 mg of polysorbate 20 in each vial which is equivalent to 0.22 mg/ml. Polysorbates may cause allergic reactions. Tell your doctor if you or your child have any known allergies.
In order to improve the traceability of biological medicinal products, the name and batch number of the administered product should be clearly recorded by your healthcare professional. Speak with your healthcare professional if you are not sure.
This medicine should be applied and supervised by appropriately trained personnel, who will also calculate the dose that you will be given. While remaining under the physician’s supervision, Replagal can be self-administered (by you or your caregiver) after appropriate training by the treating physician and/or nurse. Self-administration should occur in the presence of a responsible adult.
The recommended dose is an infusion of 0.2 mg for every kg you weigh. This would be about 14 mg or 4 vials (glass bottles) of Replagal for an average size (70 kg) individual.
For children and adolescents 7-18 years old a dose of 0.2 mg/kg every other week may be used.
Children and adolescents may be more likely than adults to experience an infusion related reaction. Tell your doctor if you experience any side effects whilst having the infusion.
Replagal has to be diluted in 9 mg/ml (0.9%) sodium chloride solution before use. After dilution Replagal is given in a vein. This will usually be in your arm.
The infusion will be given every two weeks.
Each time you are treated it will take 40 minutes for Replagal to be given to you in a vein. Your treatment will be supervised by a doctor who specialises in the treatment of Fabry Disease.
For self-administration, the dose and rate of infusion given should not be changed without the agreement of the treating physician.
If you believe you have used more Replagal than you should, please contact your doctor.
If you believe you have used less Replagal than you should, please contact your doctor.
If you have missed an infusion of Replagal, please contact your doctor.
Do not stop using Replagal without contacting your doctor.
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 (anaphylactic-type) reaction, the administration of Replagal will be immediately discontinued and an appropriate treatment will have to be initiated by your doctor.
Most side effects are mild to moderate. More than 1 in 10 people (frequency “very common”) may have a reaction during or following an infusion of Replagal (infusion related reaction). These effects include chills, headache, nausea, fever, tiredness, unsteadiness, difficulty breathing, shaking, cough and vomiting. However, some effects may be serious and may need treatment. Infusion related reactions involving the heart including heart muscle ischemia and heart failure, may occur in patients with Fabry disease involving the heart structures (frequency “not known” (cannot be estimated from the available data)). Your doctor may stop the infusion temporarily (5 - 10 min) until the symptoms go away and then begin the infusion again. Your doctor may also treat the symptoms with other medicines (antihistamines or corticosteroids). Most of the time you can still be given Replagal even if these symptoms occur.
