1. What is ADVATE and what is it used for

ADVATE contains the active substance octocog alfa, which is a recombinant human coagulation factor VIII produced by DNA technology. Factor VIII is necessary for blood to clot and to stop bleeding. In patients with hemophilia A, factor VIII is missing or does not work properly (hereditary absence of factor VIII).

ADVATE is used to treat and prevent bleeding in patients of all ages with hemophilia A (a hereditary bleeding disorder caused by the absence of factor VIII).

ADVATE is prepared without the addition of any human or animal-derived protein during the entire manufacturing process.

2. What you need to know before you use ADVATE

Do not use ADVATE

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

If you are not sure if you are allergic, consult your doctor.

Warnings and precautions

Consult your doctor before starting treatment with ADVATE. Inform your doctor if you have been previously treated with medicines containing factor VIII, especially if you developed inhibitors, as there may be a high risk that this will happen again. Inhibitors are antibodies that block factor VIII, reducing the effectiveness of ADVATE in preventing bleeding control. The development of inhibitors is a known complication in the treatment of hemophilia A. If your bleeding is not controlled with ADVATE, consult your doctor immediately.

There is a small risk that you may experience a severe allergic reaction (anaphylaxis) to ADVATE. You should be aware that the first symptoms of an allergic reaction are rash, itching, hives, generalized itching, swelling of the lips and tongue, difficulty breathing, wheezing, chest tightness, feeling of general discomfort, and dizziness. These symptoms can be a warning of anaphylactic shock, which can also cause severe dizziness, loss of consciousness, and severe breathing difficulties.

If you experience any of these symptoms, stop the administration of the medicine immediately and consult a doctor. Severe symptoms, including difficulty breathing and (near) fainting, require rapid emergency treatment.

Patients who develop factor VIII inhibitors

The formation of inhibitors (antibodies) is a known complication that can occur during treatment with all factor VIII medicines. These inhibitors, especially in large quantities, prevent the treatment from working properly, so you and your child will be carefully monitored for the development of such inhibitors. If your bleeding or your child's bleeding is not controlled with ADVATE, consult your doctor immediately.

Children and adolescents

The warnings and precautions mentioned apply to adults and children (from 0 to 18 years of age).

Using ADVATE with other medicines

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

Pregnancy andbreast-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 this medicine.

Driving and using machines

Treatment with ADVATE does not affect the ability to drive and use machines.

ADVATE contains sodium

This medicine contains 0.45 mmol of sodium (10 mg) per vial, which should be taken into consideration in patients on a low-sodium diet.

Incorrect administration of ADVATE

Incorrect administration (injection into an artery or outside a vein) should be avoided, as it can cause mild and short-term reactions at the injection site, such as bruising and redness.

3. How to use ADVATE

Treatment with ADVATE will be started by a doctor who has experience in treating patients with hemophilia A.

Your doctor will calculate your dose of ADVATE (in international units or IU) based on your condition, body weight, and whether it is to be used for prevention or treatment of bleeding. The frequency of administration will depend on how ADVATE works for you. Replacement therapy with ADVATE is usually a lifelong treatment.

Follow the instructions for administration of this medicine exactly as your doctor has told you. If you are not sure, ask your doctor again.

Prevention of bleeding

The usual dose of octocog alfa is 20 to 40 IU per kilogram of body weight, administered every 2 or 3 days. However, in some cases, especially in younger patients, more frequent administration of injections or higher doses may be required.

Treatment of bleeding

The dose of octocog alfa is calculated based on your body weight and the desired factor VIII levels. The factor VIII levels to be achieved will depend on the severity and location of the bleeding.

Dose (IU) = body weight (kg) x desired increase in factor VIII (% of normal) x 0.5

If you think that the effect of ADVATE is too weak, consult your doctor.

Your doctor will perform the necessary laboratory tests to ensure that you have adequate factor VIII levels. This is especially important if you are going to undergo major surgery.

Use in children and adolescents(from 0 to 18 years of age)

For the treatment of bleeding, the dose in children does not differ from that in adult patients. To prevent bleeding in children under 6 years of age, doses of 20 to 50 IU per kilogram of body weight are recommended 3 to 4 times a week. The administration of ADVATE in children (intravenously) does not differ from that in adults. A central venous access device (CVAD) may be necessary to allow frequent infusions of factor VIII products.

Due to the reduced injection volume of reconstituted ADVATE in 2 ml, the time to react to hypersensitivity reactions during an injection is further reduced. Therefore, caution is advised during the injection of reconstituted ADVATE in 2 ml, especially in children.

How ADVATE is administered

ADVATE is usually injected into a vein (intravenously) by your doctor or nurse. You or another person can also administer the injection of ADVATE, but only after receiving proper training. Detailed instructions for administration are described at the end of this leaflet.

If you use more ADVATE than you should

Follow the instructions for administration of ADVATE exactly as your doctor has told you. If you are not sure, ask your doctor again. If you inject more ADVATE than you should, consult your doctor as soon as possible.

If you forget to use ADVATE

Do not inject a double dose to make up for forgotten doses. Administer the next injection as scheduled and continue as your doctor has told you.

If you stop using ADVATE

Do not stop using ADVATE without consulting your doctor.

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

4. Possible side effects

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

If you experience sudden and severe allergic reactions(anaphylaxis), stop the injection immediately. Contact your doctor immediately if you have any of the following initial symptoms of allergic reactions:

• rash, itching, hives, and generalized itching,
• swelling of the lips and tongue,
• difficulty breathing, wheezing, chest tightness,
• feeling of general discomfort,
• dizziness and loss of consciousness.

Severe symptoms, such as difficulty breathing and (near) fainting, require early emergency treatment.

In children who have not been previously treated with factor VIII medicines, inhibitor antibodies (see section 2) may occur very frequently (more than 1 in 10 patients); however, in patients who have been previously treated with factor VIII (more than 150 days of treatment), the risk is infrequent (less than 1 in 100 patients). If this happens, the medicines you or your child are taking may stop working properly, and you or your child may experience persistent bleeding. In this case, contact your doctor immediately.

Instructions for Preparation andAdministration

ADVATE should not be mixed with other medicines or solvents.

It is strongly recommended to record the name and batch number of the product each time ADVATE is administered.

Instructions for Reconstitution

• Do not use after the expiration date stated on the labels and on the container.
• Do not use if the blister cap is not perfectly sealed.
• Do not refrigerate the preparation after reconstitution.

1. If the medicine is in the refrigerator, take the sealed blister (containing pre-loaded vials of powder and solvent with the reconstitution system) out of the refrigerator and let it stand at room temperature (between 15°C and 25°C).
2. Wash your hands with soap and warm water.
3. Open the ADVATE packaging by removing the cap. Remove the BAXJECT III system from the blister.
4. Place ADVATE on a flat surface with the solvent vial on top (Fig. 1). The solvent vial has a blue line. Do not remove the blue protector until instructed to do so later.
5. While holding ADVATE with one hand in the BAXJECT III system, press the solvent vial firmly with the other hand until the system is fully contracted and the solvent enters the ADVATE vial (Fig. 2). Do not tilt the system until the transfer is complete.
6. Check that the solvent transfer is complete. Gently shake until all material is dissolved. Ensure that the ADVATE powder is completely dissolved; if not, the reconstituted solution will not pass through the filter of the equipment. The medicine dissolves quickly (usually in less than 1 minute). After reconstitution, the solution should be transparent, colorless, and free of foreign particles.

Instructions for Injection

Aseptic technique is required during administration.

A luer-lock syringe is required for administration.

Important Note:

• Do not attempt to administer the injection unless you have received special training from your doctor or nurse.
• Inspect the prepared solution for particles or discoloration before administration (the solution should be transparent, colorless, and free of foreign particles).

Do not use ADVATE if the solution is not totally transparent or not completely dissolved.

1. Remove the blue protector from the BAXJECT III system. Do not introduce air into the syringe. Connect the syringe to the BAXJECT III system.
2. Invert the system (the vial with the reconstituted solution on top). Introduce the reconstituted solution into the syringe by slowly pulling back the plunger.
3. Disconnect the syringe.
4. Connect a winged infusion needle to the syringe. Inject intravenously. The solution should be administered slowly, at a rate determined by the patient's level of comfort, not exceeding 10 ml per minute. The pulse should be taken before and during the administration of ADVATE. If a significant increase in pulse is observed, the administration rate should be reduced or the injection temporarily interrupted; this usually allows the symptoms to disappear immediately (see section 4 "Possible Adverse Effects").
5. Eliminate the unused solution in an appropriate manner.

On-Demand Treatment

In the case of post-hemorrhagic episodes, factor VIII activity should not be lower than the given plasma activity level (in % of normal or IU/dl) during the corresponding period. The following table can be used as a dosage guide for hemorrhagic episodes and surgery.

The dose and frequency of administration should be adapted to the clinical response in each individual case. In certain circumstances (e.g., presence of a low inhibitor titre), higher doses than those calculated using the formula may be necessary.
