1. What is Elfabrio and what is it used for
Elfabrio contains the active substance pegunigalsidasa alfa and is used as enzyme replacement therapy in adult patients with confirmed Fabry disease. Fabry disease is a rare genetic disorder that can affect many parts of the body. In patients with Fabry disease, a fatty substance is not removed from the body's cells and accumulates in the walls of blood vessels, which can cause organ failure. This fatty substance accumulates in the cells of these patients because they do not have enough of an enzyme called α-galactosidase-A, the enzyme responsible for breaking it down. Elfabrio is used long-term to supplement or replace this enzyme in adult patients with confirmed Fabry disease.
2. What you need to know before you use Elfabrio
Do not use Elfabrio
- if you are severely allergic to pegunigalsidasa alfa or any of the other ingredients of this medicine (listed in section 6).
Warnings and precautions
Talk to your doctor before starting treatment with Elfabrio.
If you are being treated with Elfabrio, you may experience a side effect during or shortly after administration of the medicine by drip (see section 4). This side effect is called an infusion-related reactionand can sometimes be severe.
- Infusion-related reactions include dizziness, headache, nausea, low blood pressure, fatigue, and fever. If you experience an infusion-related reaction, you must inform your doctor immediately.
- If you have an infusion-related reaction, you may be given other medicines to treat it or to help prevent future reactions. These medicines may be medicines used to treat allergies (antihistamines), medicines used to treat fever (antipyretics), and medicines to control inflammation (corticosteroids).
- If the infusion-related reaction is severe, your doctor will immediately stop the infusion and start giving you the appropriate medical treatment or slow down the treatment.
- If infusion-related reactions are severe or there is a loss of effect of this medicine, your doctor will do a blood test to check if you have antibodies that could affect the outcome of the treatment.
- Most of the time, you can continue to receive Elfabrio even if you experience an infusion-related reaction.
In very rare cases, your immune system may not be able to recognize Elfabrio and cause a kidney immune disease (membranoproliferative glomerulonephritis). During clinical trials, only one case occurred, and the only symptoms reported were a temporary decrease in kidney function with excess protein in the urine. The symptoms resolved after treatment was stopped.

This information is intended only for healthcare professionals:
Dilution (using an aseptic technique)
- Determine the total number of vials needed for the infusion.
The number of vials needed is based on the total dose required for each patient and requires calculating a dose based on weight.
An example of calculating the total dose in a patient weighing 80 kg who has been prescribed a dose of 1 mg/kg is as follows:
- Patient weight (in kg) ÷ 2 = dose volume (in ml)
- Example: 80 kg (patient weight) ÷ 2 = 40 ml (volume to be extracted).
- In this example, 4 vials of the 10 ml vial (or 16 vials of the 2.5 ml vial) are needed.
- Allow the required number of vials to reach room temperature before dilution (approximately 30 minutes).
Visually inspect the vials. Do not use if the cap is missing or broken. Do not use if there are solid particles or if a color change has occurred.
Avoid shaking or agitating the vials.
- Withdraw and discard the same volume calculated in step 1 from a sodium chloride 9 mg/ml (0.9%) infusion solution bag.
- Withdraw the required volume of the Elfabrio solution from the vials and dilute with a sodium chloride 9 mg/ml (0.9%) infusion solution up to the total volume based on the patient's weight as specified in the table below.
Minimum total infusion volume for patients based on body weight
Patient weight | Minimum total infusion volume |
<70 kg | 150 ml |
70-100 kg | 250 ml |
>100 kg | 500 ml |
Inject the Elfabrio solution directly into the infusion bag.
DO NOT inject into the air space within the bag.
Gently invert the infusion bag to mix the solution, avoiding vigorous shaking or agitation.
The diluted solution must be administered using a 0.2 μm low-protein-binding in-line filter.
