1. What Refixia is and what it is used for

What Refixia is

Refixia contains the active substance nonacog beta pegol. It is a long-acting version of factor IX.

Factor IX is a protein naturally found in the blood that helps to stop bleeding.

What Refixiais used for

Refixia is used to treat and prevent bleeding in patients 12 years and above with haemophilia B (inborn factor IX deficiency).

In patients with haemophilia B, factor IX is missing or does not work properly. Refixia replaces this faulty or missing factor IX and helps blood to form clots at the site of bleeding.

2. What you need to know before you use Refixia

Do not use Refixia

  • if you are allergic to the active substance or any of the other ingredients of this medicine (listed

in section 6).

  • if you are allergic to hamster proteins.

If you are not sure if either of the above applies to you, talk to your doctor before using this medicine.

Warnings and precautions

Traceability

It is important to keep a record of the batch number of your Refixia. So, every time you get a new package of Refixia, note down the date and the batch number (which is on the packaging after Lot) and keep this information in a safe place.

Allergic reactions and development of inhibitors

There is a rare risk that you may experience a sudden and severe allergic reaction (e.g. anaphylactic reaction) to Refixia. Stop the injection and contact your doctor or an emergency unit immediately if you have signs of an allergic reaction such as rash, hives, weals, itching of large areas of skin, redness and/or swelling of lips, tongue, face or hands, difficulty in swallowing or breathing, shortness of breath, wheezing, tightness of the chest, pale and cold skin, fast heartbeat, and/or dizziness.

Your doctor may need to treat you promptly for these reactions. Your doctor may also carry out a blood test to check if you have developed factor IX inhibitors (neutralising antibodies) against your medicine, as inhibitors may develop together with allergic reactions. If you have such inhibitors, you may have a higher risk of sudden and severe allergic reactions (e.g. anaphylactic reaction) during future treatment with factor IX.

Because of the risk of allergic reactions with factor IX, your initial treatment with Refixia should be given in a medical clinic or in the presence of health care professionals where proper medical care for allergic reactions can be provided if needed.

Talk to your doctor immediately if your bleeding does not stop as expected or if you have to significantly increase the amount of Refixia you need to stop a bleed. Your doctor will do a blood test to check if you have developed inhibitors (neutralising antibodies) against Refixia. The risk for developing inhibitors is highest in people who have have not been treated with factor IX medicines before, typically small children.

Blood clots

Tell your doctor, if any of the following apply to you as there is an increased risk of blood clots during treatment with Refixia:

  • you have recently had surgery
  • you suffer from other serious illness e.g. liver disease, heart disease, or cancer
  • you have risk factors for heart disease e.g high blood pressure, obesity, or smoking.

Kidney disorder (nephrotic syndrome)

There is a rare risk of developing a specific kidney disorder called “nephrotic syndrome” following high doses of factor IX in haemophilia B patients with factor IX inhibitors and a history of allergic reactions.

Catheter-related problems

If you have a central venous access device (CVAD), you may develop infections or blood clots at the site of the catheter.

Other medicines and Refixia

Tell your doctor if you are taking, have recently taken or might take any other medicines.

Pregnancy and breast-feeding

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor for advice before using Refixia.

Driving and using machines

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

Refixia contains sodium

This medicine contains less than 1 mmol sodium (23 mg) per vial, that is to say essentially “sodium-free”.

3. How to use Refixia

Treatment with Refixia will be started by a doctor who is experienced in the care of patients with haemophilia B. Always use this medicine exactly as your doctor has told you. Check with your doctor if you are not sure about how to use Refixia.

Your doctor will calculate the right dose for you. The dose will depend on your weight and what the medicine is being used for.

Prevention of bleeding

The usual dose of Refixia is 40 international units (IU) per kg of body weight. This is given as one injection every week. Your doctor may choose another dose or change how often the injections should be given, based on your need.

Treatment of bleeding

The usual dose of Refixia is 40 international units (IU) per kg of body weight. Depending on the location and the severity of bleeding you may need a higher dose (80 IU per kg) or extra injections. Discuss with your doctor the dose and number of injections you need.

Use in children and adolescents

Refixia should be used only in adolescents (12 years and above). The dose in adolescents is also calculated according to body weight and is the same dose as for adults.

How Refixia is given

Refixia is available as powder and solvent that is made up into a solution (reconstitution) and given as an injection into a vein. See “Instructions on how to use Refixia” for more information.

If you use more Refixia than you should

If you use more Refixia than you should, contact your doctor.

If you have to significantly increase the amount of Refixia you need to stop a bleed, talk to your doctor immediately. For further information, see section 2 “Allergic reactions and development of inhibitors”.

If you forget to use Refixia

If you forget a dose, inject the missed dose as soon as you remember. Do not inject a double dose to make up for a forgotten dose. If you are in doubt contact your doctor.

If you stop using Refixia

If you stop using Refixia you may no longer be protected against bleeding or a current bleed may not stop. Do not stop using Refixia without talking to your doctor.

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

Instructions on how to use Refixia

Read these instructions carefully before using Refixia.

Refixia is supplied as a powder. Before injection a solution must be made up (reconstituted) with the solvent supplied in the syringe. The solvent is a histidine solution. The reconstituted solution must be injected into a vein (intravenous (IV) injection). The equipment in this package is designed to reconstitute and inject Refixia.

You will also need an infusion set (tubing and butterfly needle), sterile alcohol swabs, gauze pads and plasters. These items are not included in the Refixia package.

Do not use the equipment without proper training from your doctor or nurse.

Always wash your hands and ensure that the area around you is clean.

When you prepare and inject medicine directly into the veins, it is important to use a clean and germ-free (aseptic) technique. Incorrect technique can introduce germs that can infect the blood.

Do not open the equipment until you are ready to use it.

Do not use the equipment if it has been dropped, or if it is damaged. Use a new package instead.

Do not use the equipment if it has expired. Use a new package instead. The expiry date is printed on the outer carton, on the vial, on the vial adapter, and on the pre-filled syringe.

Do not use the equipment if you suspect it is contaminated. Use a new package instead.

Do not dispose of any of the items until after you have injected the reconstituted solution.

The equipment is for single use only.

be clear and colourless and no particles should be visible. If you notice particles or discolouration, do not use it. Use a new package instead.

O

Refixia is recommended to be used immediately after it has been reconstituted. This is because if left, the medicine may no longer be sterile and could cause infections.

If you cannot use the reconstituted Refixia solution immediately, it should be used within 4 hours when stored at room temperature (up to 30 °C) and within 24 hours when stored in a refrigerator (2 °C – 8 °C). Store the reconstituted product in the vial.

Do not freeze reconstituted Refixia solution or store it in syringes.

Keep reconstituted Refixia solution out of direct light.

If your dose requires more than one vial, repeat steps A to J with additional vials, vial adapters and pre-filled syringes until you have reached your required dose.

Keep the plunger rod pushed completely in.

Turn the syringe with the vial upside down.

Stop pushing the plunger rod and let it move back on its own while the reconstituted solution fills the syringe.

Pull the plunger rod slightly downwards to draw the reconstituted solution into the syringe.

In case you only need part of the entire vial, use the scale on the syringe to see how much reconstituted solution you withdraw, as instructed by your doctor or nurse.

If, at any point, there is air in the syringe, inject the air back into the vial.

While holding the vial upside down, tap the syringe gently to let any air bubbles rise to the top.

Push the plunger rod slowly until all air bubbles are gone.

Unscrew the vial adapter with the vial.

Do not touch the syringe tip. If you touch the syringe tip, germs from your fingers can be transferred.



  • 5. Inject the reconstituted solution

Refixia is now ready to inject into your vein.

  • Inject the reconstituted solution as instructed by your doctor or nurse.
  • Inject slowly over 1 to 3 minutes.
  • Do not mix Refixia with any other intravenous infusions or medicines.

Injecting Refixia via needleless connectors for intravenous (IV) catheters

Caution: The pre-filled syringe is made of glass and is designed to be compatible with standard luer-lock connections. Some needleless connectors with an internal spike are incompatible with the pre-filled syringe. This incompatibility may prevent administration of the medicine and/or result in damage to the needleless connector.

Injecting the solution via a central venous access device (CVAD) such as a central venous catheter or a subcutaneous port:

  • Use a clean and germ-free (aseptic) technique. Follow the instructions for proper use for your

connector and CVAD in consultation with your doctor or nurse.


  • Injecting into a CVAD may require using a sterile 10 ml plastic syringe for withdrawal of the

reconstituted solution. This should be done right after step J.

  • If the CVAD line needs to be flushed before or after Refixia injection, use sodium chloride

9 mg/ml solution for injection.

Disposal

  • After injection, safely dispose of all

unused Refixia solution, the syringe with the infusion set, the vial with the vial adapter and other waste materials as instructed by your pharmacist.

Do not throw it out with the ordinary household waste.

Do not disassemble the equipment before disposal.

Do not reuse the equipment.
