1. What is ALPROLIX and what is it used for

ALPROLIX contains the active substance eftrenonacog alfa, a recombinant coagulation factor IX, Fc fusion protein. Factor IX is a protein that is naturally produced by the body and is necessary for blood to form clots and stop bleeding.

ALPROLIX is a medicine used to treat and prevent bleeding in patients of all ages with hemophilia B (a bleeding disorder caused by a deficiency of factor IX).

ALPROLIX is prepared using recombinant technology without the addition of any human or animal component in the manufacturing process.

How ALPROLIX works

In patients with hemophilia B, factor IX is missing or does not work properly. This medicine is used to replace the missing or deficient factor IX. ALPROLIX increases factor IX concentrations in the blood and temporarily corrects the tendency to bleed. The Fc fusion protein in this medicine prolongs the duration of action of the medicine.

2. What you need to know before you use ALPROLIX

Do not use ALPROLIX

• if you are allergic to eftrenonacog alfa or any of the other ingredients of this medicine (listed in section 6).

Warnings and precautions

Talk to your doctor, pharmacist, or nurse before you start using ALPROLIX.

• There is a small chance that you may have an anaphylactic reaction (a severe and sudden allergic reaction) to ALPROLIX. Signs of allergic reactions include generalized itching, hives, tightness in the chest, difficulty breathing, and low blood pressure. If any of these symptoms occur, stop the injection immediately and contact your doctor. Due to the risk of allergic reactions with factor IX, your first administrations of ALPROLIX should be performed under medical observation in a place where adequate medical care can be provided in case of allergic reactions.

• Talk to your doctor if you think you are not getting control of bleeding with the dose you are receiving, as there may be several reasons for this. For example, the formation of antibodies (also known as inhibitors) against factor IX is a known complication that can occur during treatment of hemophilia B. Antibodies prevent the treatment from working properly. Your doctor will check if this is the case. Do not increase the total dose of ALPROLIX to control bleeding without talking to your doctor first.

Patient with a factor IX inhibitor may have a higher risk of anaphylaxis during future treatments with factor IX. Therefore, if you experience allergic reactions as described above, you should have a test to check for the presence of an inhibitor.

Factor IX medicines may increase the risk of unwanted blood clots in your body, especially if you have risk factors for developing blood clots. Symptoms of a possible unwanted blood clot may include: pain and/or tenderness along a vein, unexpected swelling of an arm or leg, or sudden shortness of breath or difficulty breathing.

Cardiovascular disorders

If you have been told that you have a heart condition or are at risk of having one, be extra careful when using factor IX and talk to your doctor.

Catheter-related complications

If you need a central venous access device (CVAD), you should be aware of the risk of CVAD-related complications, including local infections, bacteria in the blood, and blood clots at the catheter insertion site.

Documentation

We strongly recommend that every time ALPROLIX is administered, the name and batch number of the product are recorded.

Other medicines and ALPROLIX

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

Pregnancy and breastfeeding

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 using this medicine.

Driving and using machines

ALPROLIX has no influence on the ability to drive and use machines.

ALPROLIX contains sodium

This medicine contains less than 1 mmol of sodium (23 mg) per vial, i.e., it is essentially "sodium-free". In case of treatment with several vials, the total sodium content should be taken into account.

3. How to use ALPROLIX

Treatment with ALPROLIX will be started by a doctor who is experienced in the care of patients with hemophilia. Follow exactly the administration instructions of this medicine given by your doctor (see section 7). If you are unsure, talk to your doctor, pharmacist, or nurse.

ALPROLIX is given by injection into a vein. You or another person can administer it after receiving the necessary training. Your doctor will decide the dose (in International Units or "IU") you will receive. The dose will depend on your individual needs for factor IX replacement treatment and whether it is used for prevention or treatment of bleeding. Talk to your doctor if you think you are not getting control of bleeding with the dose you are receiving.

How often you will need an injection will depend on how well the medicine is working for you. Your doctor will perform the relevant laboratory tests to ensure you have adequate factor IX concentrations in the blood.

Treatment of bleeding

The dose of ALPROLIX is calculated based on your body weight and the desired factor IX concentrations. The target factor IX concentrations depend on the severity and location of the bleeding.

Prevention of bleeding

If you are using ALPROLIX to prevent bleeding, your doctor will calculate the dose.

The usual dose of ALPROLIX is 50 IU per kilogram of body weight, administered once a week, or 100 IU per kilogram of body weight, administered once every 10 days. Your doctor may adjust the dose or interval. In some cases, especially in younger patients, shorter dosing intervals or higher doses may be necessary.

Use in children and adolescents

ALPROLIX can be used in children and adolescents of all ages. In children under 12 years, higher doses or more frequent injections may be necessary, and the usual dose is 50 to 60 IU per kilogram of body weight, administered once every 7 days.

If you use more ALPROLIX than you should

Tell your doctor as soon as possible. Follow exactly the administration instructions of ALPROLIX given by your doctor. If you are unsure, talk to your doctor, pharmacist, or nurse.

If you forget to use ALPROLIX

Do not take a double dose to make up for forgotten doses. Take your dose as soon as you remember and then continue with your normal dosing schedule. If you are not sure what to do, talk to your doctor, pharmacist, or nurse.

If you stop using ALPROLIX

Do not stop using ALPROLIX without talking to your doctor. If you stop using ALPROLIX, you may no longer be protected against bleeding or an existing bleed may not stop.

If you have any further questions on the use of this medicine, ask your doctor, pharmacist, or nurse.

4. Possible side effects

Like all medicines, this medicine can cause side effects, although not everybody gets them.

If a severe and sudden allergic reaction (anaphylactic reaction) occurs, the injection should be stopped immediately. Contact your doctor immediately if you experience any of the following symptoms of allergic reactions: swelling of the face, rash, generalized itching, hives, tightness in the chest, difficulty breathing, and low blood pressure.

In children who have not received previous treatment with factor IX-containing medicines, it is common for inhibitors to form (in up to 1 in 10 patients) (see section 2). If this happens, the medicine may stop working properly, and your child may experience persistent bleeding. If this happens, contact your doctor immediately.

The following side effects may occur with this medicine.

Common side effects (may affect up to 1 in 10 people):headache, numbness or tingling in the mouth, pain in the side with blood in the urine (obstructive uropathy), and redness at the injection site.

Children who have not received previous treatment with factor IX-containing medicines: factor IX inhibitors, hypersensitivity.

Uncommon side effects (may affect up to 1 in 100 people):dizziness, altered taste, bad breath, feeling tired, pain at the injection site, rapid heartbeat, blood in the urine (hematuria), pain in the side (renal colic), low blood pressure, and decreased appetite.

Rare side effects (frequency cannot be estimated from the available data):severe and sudden allergic reaction and potentially life-threatening allergic reaction (anaphylactic shock).

Reporting of side effects

If you experience any side effects, talk to your doctor, pharmacist, or nurse, even if it is possible that they are not listed in this leaflet. You can also report side effects directly through the national reporting system listed in Appendix V. By reporting side effects, you can help provide more information on the safety of this medicine.
