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

ReFacto AF contains the active substance moroctocog alfa, human coagulation factor VIII. Factor VIII is necessary for blood to clot and stop bleeding. In patients with hemophilia A (congenital factor VIII deficiency), it is either not present or does not work properly.

ReFacto AF is used to treat and prevent (prophylaxis) bleeding episodes in adults and children of all ages (including newborns) with hemophilia A.

2. What you need to know before you use ReFacto AF

Do not use ReFacto AF

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

Talk to your doctor if you are unsure.

Warnings and precautions

Talk to your doctor or pharmacist before you start using ReFacto AF

• if you have allergic reactions. Some signs of allergic reactions are difficulty breathing, shortness of breath, swelling, hives, itching, chest tightness, wheezing, and low blood pressure. Anaphylaxis is a severe allergic reaction that causes difficulty swallowing or breathing, redness or swelling of the hands, face, or both. If you experience any of these symptoms, stop the infusion immediately and contact your doctor or seek emergency medical attention immediately. In cases of severe allergic reactions, alternative treatment should be considered.

• the formation of inhibitors (antibodies) is a known complication that can occur during treatment with all factor VIII medicines. These inhibitors, especially at high levels, can prevent the treatment from working properly, so you or your child will be closely monitored for the development of such inhibitors. If you 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 emergency medical attention immediately.

Other medicines and ReFacto AF

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

Pregnancy, breastfeeding, and fertility

If you are pregnant or breastfeeding, think you may be pregnant, or plan 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 and use machines.

ReFacto AF contains sodium

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

3. How to use ReFacto AF

Follow the instructions for administration of this medicine exactly as prescribed by your doctor. If you are unsure, consult your doctor or pharmacist again.

Treatment with ReFacto AF should be started by a doctor experienced in the treatment of patients with hemophilia 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 injection into a vein and the injection takes several minutes. ReFacto AF injections can be administered by patients or their caregivers, provided they have received appropriate training.

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

Consult your doctor before traveling. When traveling, you should carry your factor VIII product in sufficient quantity for the planned treatment.

It is recommended that each time you administer ReFacto AF, you record the name on the label and the batch number of the product. You can stick one of the detachable labels found on the vial to document the batch number in your diary or to report any side effects.

Reconstitution and administration

The instructions below are a guide for the reconstitution and administration of ReFacto AF. Patients should follow the specific reconstitution and administration instructions provided by their doctors.

For reconstitution, use only the pre-filled syringe provided in the pack. For administration, other sterile disposable syringes can be used.

ReFacto AF is administered by intravenous (IV) infusion after reconstituting the lyophilized powder for injection with the provided syringe of solvent, [a 9 mg/ml (0.9%) sodium chloride injection solution]. ReFacto AF must not be mixed with other infusion solutions.

Always wash your hands before performing reconstitution and administration. During the reconstitution procedure, an aseptic technique (i.e., clean and germ-free) must be followed.

Reconstitution:

1. Wait for the ReFacto AF lyophilized vial and the pre-filled syringe of solvent to reach room temperature.

1. Remove the plastic cap from the ReFacto AF vial to expose the central part of the rubber stopper.

1. Clean the top of the vial with the provided alcohol swab or another antiseptic solution and wait for it to dry. After cleaning, do not touch the rubber stopper with your hand or let it touch any surface.

1. Remove the cap from the plastic vial adapter package. Do not remove the adapter from the package.

1. Place the vial on a flat surface. While holding the adapter package, place the adapter over the vial and press firmly on the package until the adapter snaps into place on top of the vial and the adapter's spike penetrates the vial's stopper.

1. Remove the adapter package and discard it.

1. Attach the plunger rod to the solvent syringe by inserting the rod into the syringe's cap opening, pressing, and turning firmly until it is seated in the cap.

1. Remove the plastic tip cap from the solvent syringe by breaking the perforation of the cap. This is done by bending the cap up and down until the perforation breaks. Do not touch the inside of the cap or the tip of the syringe. The cap may need to be replaced (if ReFacto AF reconstituted is not administered immediately), so it should be set aside on its top.

1. Place the vial on a flat surface. Connect the solvent syringe to the vial adapter by inserting the syringe tip into the adapter opening while pressing and turning firmly clockwise until it is secure.

1. Slowly push the plunger rod to inject all of the solvent into the ReFacto AF vial.

1. With the syringe still connected to the adapter, gently swirl the vial until the powder is dissolved.

1. Visually inspect the final solution for particles before administration. The solution should appear clear to slightly opalescent and colorless.

Note: If you use more than one vial of ReFacto AF per infusion, each vial must be reconstituted following the above instructions. The solvent syringe should be removed, leaving the vial adapter in place, and another large luer-lock syringe can be used to withdraw the reconstituted contents from each individual vial.

1. Make sure the syringe plunger rod is still fully inserted, turn the vial upside down, and slowly push the entire solution back into the syringe through the vial adapter.

1. Separate the syringe from the vial adapter by pulling the syringe and turning it counterclockwise. Discard the vial with the adapter.

Note: If the reconstituted solution is not used immediately, the syringe cap should be carefully replaced. Do not touch the syringe tip or the inside of the cap.

ReFacto AF should be used immediately or within 3 hours after reconstitution. Before administration, the reconstituted solution can be stored at room temperature.

Administration (Intravenous Infusion):

ReFacto AF should be administered using the infusion set provided in this pack and the pre-filled syringe of solvent or a sterile disposable plastic syringe with a luer-lock fitting.

1. Attach the syringe to the luer-lock connection of the infusion set.

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

1. Insert the infusion set needle into the vein, following your doctor's instructions, and remove the tourniquet. Remove any air that may be in the infusion set by aspirating it into the syringe. The reconstituted product should be injected intravenously over several minutes. Your doctor may adjust the recommended infusion rate to make it more comfortable.

Discard the unused solution, empty vial(s), and used needles and syringes in an appropriate container for disposing of medical waste, as these materials may harm others if not disposed of properly.
