1. What ReFacto AF is and what it is used for

ReFacto AF contains the active substance moroctocog alfa, human coagulation factor VIII. Factor VIII is necessary for blood to form clots and stop bleeding. In patients with haemophilia A (an inherited factor VIII deficiency), factor VIII is either missing or does not function properly.

ReFacto AF is used for the treatment and prevention (prophylaxis) of bleeding episodes in adults and children of all ages (including newborns) with haemophilia A.

2. What you need to know before using ReFacto AF

Do not use ReFacto AF

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

Consult your doctor if you have any doubts.

Warnings and precautions

Consult your doctor or pharmacist before starting to use ReFacto AF

• if you experience allergic reactions. Some signs of allergic reactions include difficulty breathing, shortness of breath, swelling, hives, itching, chest tightness, wheezing, and low blood pressure. Anaphylaxis is a serious allergic reaction causing difficulty swallowing or breathing, redness or swelling of the hands, face, or both. If any of these symptoms occur, stop the infusion immediately and contact your doctor or seek immediate emergency medical assistance. Alternative treatment should be considered in cases of severe allergic reactions.

• the development of inhibitors (antibodies) is a known complication that may occur during treatment with all factor VIII-containing medicines. These inhibitors, especially at high levels, may prevent the treatment from working properly, so you or your child will be closely monitored for the development of such inhibitors. If your bleeding or your child's bleeding is not controlled with ReFacto AF, contact your doctor immediately.

• if your bleeding does not stop as expected, contact your doctor or seek immediate emergency medical assistance.

Other medicines and ReFacto AF

Inform your doctor or pharmacist if you are taking, have recently taken, or might need to take any other medicines.

Pregnancy, breastfeeding, and fertility

If you are pregnant or breastfeeding, think you may be pregnant, or are planning to become pregnant, consult your doctor or pharmacist before using this medicine.

Driving and using machines

ReFacto AF has no influence on the ability to drive or operate machinery.

ReFacto AF contains sodium

After reconstitution, ReFacto AF contains 1.27 mmol (or 29 mg) of sodium (main component of table/cooking salt) per pre-filled syringe. This corresponds to 1.5% of the maximum recommended daily sodium intake for an adult. Depending on your body weight and your dose of ReFacto AF, you may receive multiple pre-filled syringes. This should be taken into account if you are on a low-sodium diet.

3. How to use ReFacto AF

Follow exactly the administration instructions for this medicine given by your doctor. If in doubt, consult your doctor or pharmacist again.

Treatment with ReFacto AF should be initiated by a physician experienced in the treatment of patients with haemophilia A. Your doctor will decide the dose of ReFacto AF you should receive. This dose and its duration will depend on your individual needs for factor VIII replacement therapy. ReFacto AF is administered by intravenous injection, which takes several minutes. Injections of ReFacto AF may be given by patients or their caregivers, provided they have received appropriate training.

During your treatment, your doctor may adjust the dose of ReFacto AF you receive.

Consult your doctor before travelling. When travelling, you should carry sufficient supplies of your factor VIII product for the intended treatment duration.

It is recommended that each time ReFacto AF is administered, you record the name shown on the packaging and the product's batch number. You may affix one of the peel-off labels from the pre-filled syringe to document the batch number in your diary or to report any adverse reactions.

Reconstitution and administration

The instructions provided below are a guide for reconstituting and administering ReFacto AF supplied in a pre-filled syringe. Patients must follow the specific reconstitution and administration instructions provided by their physicians.

ReFacto AF is administered by intravenous (IV) infusion after reconstitution. The pre-filled syringe consists of two chambers: one chamber contains the lyophilised powder of ReFacto AF and the other chamber contains the solvent [sodium chloride solution 9 mg/mL (0.9%)]. Throughout these instructions, this device will be referred to as the pre-filled syringe.

For reconstitution, use only the pre-filled syringe supplied in the package. For administration, other sterile disposable syringes may be used.

ReFacto AF must not be mixed with other infusion solutions.

Note: If you need to use more than one pre-filled syringe of ReFacto AF per infusion, each syringe must be reconstituted according to the specific instructions. To withdraw the reconstituted contents from each syringe, a 10 mL syringe or a larger syringe with a luer lock (not included in this kit) may be used (see Additional Instructions).

Preparation

1. Always wash your hands before performing the following procedures.
2. During the reconstitution procedure, an aseptic technique (i.e., clean and germ-free) must be followed.
3. To minimise exposure to air, all components used in the reconstitution and administration of this product should be used as soon as possible after opening the sterile packaging.

Reconstitution

1. Allow the pre-filled syringe to reach room temperature.
2. Remove the components of the ReFacto AF pre-filled syringe kit and place them on a clean surface, ensuring you have all the materials you will need.
3. Hold the plunger as shown in the diagram. Firmly screw the plunger into the opening of the ReFacto AF pre-filled syringe, pushing and twisting clockwise until resistance is felt (approximately 2 turns).

During the reconstitution process, it is important to keep the ReFacto AF pre-filled syringe in an upright position (with the white powder above the clear solution) to prevent possible leakage.

1. Holding the pre-filled syringe upright, remove the white safety seal by bending it from left to right (or with a careful rocking motion) to break the seal on the stopper and expose the grey rubber stopper of the ReFacto AF pre-filled syringe.

1. Remove the sterile blue venting cap from its packaging.

While holding the ReFacto AF pre-filled syringe upright, remove the grey rubber stopper and replace it with the blue protective venting cap. This venting cap has small openings that allow air to escape, preventing pressure build-up. Avoid touching the open end of the syringe or the blue protective venting cap.

1. Push the plunger slowly and carefully until the two plungers of the pre-filled syringe meet and all the solvent is transferred into the upper chamber containing the ReFacto AF powder.

Note: To prevent fluid leakage from the tip of the syringe, do not push the plunger with excessive force.

1. With the ReFacto AF pre-filled syringe held upright, gently agitate it several times until the powder is completely dissolved.

Visually inspect the final solution for particles or discoloration. The solution should appear clear to slightly opalescent and colourless. Discard the pre-filled syringe if particles or discoloration are observed.

1. Continuing with the ReFacto AF pre-filled syringe in an upright position, advance the plunger until almost, but not all, of the air has been removed from the (upper) chamber.

ReFacto AF must be used within 3 hours after reconstitution or after removal of the grey stopper from the pre-filled syringe.

If you do not use the ReFacto AF solution immediately, store the syringe upright with the blue venting cap still attached to the pre-filled syringe until ready for infusion. The reconstituted solution may be stored at room temperature for up to 3 hours. If not used within 3 hours, discard it.

Administration (Intravenous infusion)

Your doctor or another healthcare professional will teach you how to perform the ReFacto AF infusion. Once you have learned how to perform self-infusion, you may follow the instructions included in this leaflet.

ReFacto AF is administered by intravenous (IV) infusion after reconstitution of the powder with the solvent (0.9% sodium chloride). After reconstitution and before administration, ReFacto AF must be visually inspected for particles or discoloration.

ReFacto AF should be administered using the infusion set provided in this kit, unless your doctor or another healthcare professional has given you different instructions.

1. Remove the blue venting cap and firmly attach the infusion device to the ReFacto AF pre-filled syringe.

1. Apply a tourniquet and prepare the injection site by thoroughly cleaning the skin with one of the alcohol swabs provided.

1. Remove the protective cap from the needle and insert the butterfly needle of the infusion set into the vein, following your doctor’s or healthcare professional’s instructions. The reconstituted product should be injected intravenously over several minutes. Your doctor may adjust the recommended infusion rate to make it more comfortable. Speak with your doctor or healthcare professional about the infusion procedure. Do not perform self-infusion unless you have been properly trained.

Reconstituted ReFacto AF must not be administered in the same tubing or container as other medications.

1. After ReFacto AF infusion, remove and discard the infusion set. The amount of medication remaining in the infusion set does not affect your treatment.

Note: Dispose of unused solution, empty pre-filled syringes, and used medical materials in an appropriate container for medical waste, as these materials may harm others if not properly disposed of.

It is recommended to record the batch number shown on the label of the ReFacto AF pre-filled syringe each time you use ReFacto AF. You may use the peel-off label from the ReFacto AF pre-filled syringe to document the batch number.

Additional Instructions:

Multiple reconstitution of ReFacto AF from pre-filled syringes into a 10 mL syringe or a larger syringe with a luer lock (10 mL syringes or luer-lock syringes are not provided in the kit).

The following instructions are for using multiple ReFacto AF pre-filled syringe kits with a 10 mL syringe or a larger syringe with a luer lock.

1. Reconstitute all ReFacto AF pre-filled syringes following the instructions above (see Reconstitution and Administration).

Hold the ReFacto AF pre-filled syringe upright and slowly push the plunger until almost, but not all, of the air has been expelled from the chamber containing the product.

1. Remove the luer-to-luer syringe connector from its packaging (luer-to-luer syringe connectors are not included).

2. Connect a sterile 10 mL syringe or a larger luer-lock syringe to one open port of the syringe connector, and connect the ReFacto AF pre-filled syringe to the remaining open port on the opposite side.

1. With the ReFacto AF pre-filled syringe on top, slowly push the plunger until the contents are emptied into the 10 mL syringe or larger luer-lock syringe.

1. Remove the ReFacto AF pre-filled syringe and repeat steps 3 and 4 for additional reconstituted syringes.

2. Remove the luer-to-luer syringe connector from the 10 mL syringe or larger luer-lock syringe and connect the infusion set as described above in the administration instructions for the pre-filled syringe [see Administration (Intravenous infusion)].

Note: Dispose of unused solution, empty pre-filled syringes, and used medical materials in an appropriate container for medical waste, as these materials may harm others if not properly disposed of.
