1. what nuwiq is and what it is used for

Nuwiq contains the active substance human recombinant coagulation factor VIII (simoctocog alfa). Factor VIII is necessary for the blood to form clots and stop bleeding. In patients with haemophilia A (inborn factor VIII deficiency), factor VIII is missing or not working properly.

Nuwiq replaces the missing factor VIII and is used for treatment and prevention of bleeding in patients with haemophilia A and can be used for all age groups.

2. what you need to know before you use nuwiqdo not use nuwiq- if you are allergic to the active substance simoctocog alfa or any of the other ingredients of this medicine (listed in section 6).

If you are unsure about this, ask your doctor.

Warnings and precautions

Talk to your doctor before using Nuwiq.

There is a rare chance that you may experience an anaphylactic reaction (a severe, sudden allergic reaction) to Nuwiq. You should be aware of the early signs of allergic reactions as they are listed in section 4 “Allergic reactions”.

If any of these symptoms occur, stop the injection immediately and contact your doctor.

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, stop the treatment working properly and you or your child will be monitored carefully for the development of these inhibitors. If you or your child's bleeding is not being controlled with Nuwiq, tell your doctor immediately.

Cardiovascular events

In patients with existing cardiovascular risk factors, substitution therapy with FVIII may increase the cardiovascular risk.

Catheter-related complications

If you require a central venous access device (CVAD), risk of CVAD-related complications including local infections, presence of bacteria in the blood and catheter site thrombosis should be considered.

It is strongly recommended that every time that Nuwiq is administered, the name and batch number of the product are recorded in order to maintain a link between you and the batch of the medicinal product.

Other medicines and Nuwiq

Tell your doctor if you are using, have recently used or might use 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 this medicine.

Driving and using machines

Nuwiq has no influence on your ability to drive and use machines.

Nuwiq contains sodium

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

However, depending on your body weight and your dose of Nuwiq, you could receive more than one vial. This should be taken into consideration if you are on a controlled sodium diet.

3. how to use nuwiq

Treatment with Nuwiq will be started by a doctor who is experienced in the care of patients with haemophilia A. Always use this medicine exactly as your doctor or nurse has told you. Check with your doctor or nurse if you are not sure.

Nuwiq is usually injected into a vein (intravenously) by your doctor or a nurse who are experienced in the care of patients with haemophilia A. You or someone else might also give your Nuwiq injection, but only after receiving adequate training.

Your doctor will calculate your dose of Nuwiq (in international units = IU) depending on your condition and body weight, and on whether it is used for prevention or treatment of bleeding. How often you need an injection will depend on how well Nuwiq is working for you. Usually, treatment for haemophilia A is a life-long treatment.

Prevention of bleeding

The usual dose of Nuwiq is 20 to 40 IU per kg body weight, given every 2 to 3 days. However, in some cases, especially in younger patients, more frequent injections or higher doses may be necessary.

Treatment of bleeding

The dose of Nuwiq is calculated depending on your body weight and the factor VIII levels to be achieved. The target factor VIII levels will depend on the severity and location of the bleeding.

If you have the impression that the effect of Nuwiq is insufficient, talk to your doctor. Your doctor will perform appropriate laboratory tests to make sure that you have adequate factor VIII levels. This is particularly important if you are having major surgery.

Patients developing factor VIII inhibitors

If your plasma factor VIII fails to reach expected levels with Nuwiq, or if bleeding is not adequately controlled, it could be due to the development of factor VIII inhibitors. This will be checked by your doctor. You might need a higher dose of Nuwiq or a different product to control bleedings. Do not increase the total dose of Nuwiq to control your bleeding without consulting your doctor.

Use in children and adolescents

The way Nuwiq is used in children and adolescents does not differ from the way it is used in adults. Because factor VIII products may have to be given more often in children and adolescents, a central venous access device (CVAD) may need to be fitted. A CVAD is an external connector that allows access to the bloodstream through a catheter without injection through the skin.

If you use more Nuwiq than you should

No symptoms of overdose have been reported. If you have injected more Nuwiq than you should, please inform your doctor.

If you forget to use Nuwiq

Do not take a double dose to make up for a forgotten dose.

Proceed with the next dose immediately and continue as advised by your doctor.

If you stop using Nuwiq

Do not stop using Nuwiq 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.

Allergic reactions

You should be aware of the early signs of allergic reactions. If severe, sudden allergic reactions (anaphylactic) occur (very rare: may affect up to 1 in 10,000 people), the injection must be stopped immediately. You must contact your doctor immediately if you notice any of the following symptoms:

– rash, hives, wheals, generalised itching,
– swelling of lips and tongue,
– difficulty in breathing, wheezing, tightness in the chest,
– general feeling of being unwell,
– dizziness and loss of consciousness.

These symptoms can be early symptoms of an anaphylactic shock. If any of these symptoms occur, stop the injection immediately and contact your doctor. Severe symptoms require prompt emergency treatment.

Very common side effects may affect more than 1 in 10 people Factor VIII inhibition in previously untreated patients.

For children and adolescents not previously treated with factor VIII medicines, inhibitor antibodies (see section 2) may form very commonly (more than 1 in 10 patients).

However for patients who have received previous treatment with factor VIII (more than 150 days of treatment) the risk is uncommon (less than 1 in 100 patients). If this happens, your or your child's medicines may stop working properly and you or your child may experience persistent bleeding. If this happens, you should contact your doctor immediately.

Common side effects may affect up to 1 in 10 people Hypersensitivity, fever.

Uncommon side effects may affect up to 1 in 100 people

Tingling or numbness (paraesthesia), headache, injection site inflammation, injection site pain, back pain, vertigo, dry mouth, dizziness, a vague feeling of bodily discomfort, shortness of breath, haemorrhagic anaemia, non-neutralising antibody positive (in PTPs).

The following information is intended for healthcare professionals only:

On-demand treatment

The amount to be administered and the frequency of administration should always be oriented to the clinical effectiveness in the individual case.

In the case of the following haemorrhagic events, factor VIII activity should not fall below the given plasma activity level (in % of normal or IU/dL) in the corresponding period. The following table can be used to guide dosing in bleeding episodes and surgery.

Degree of haemorrhage/ Type of surgical procedure	Factor VIII level required (%) (IU/dL)	Frequency of doses (hours)/ Duration of therapy (days)
Haemorrhage
Early haemarthrosis, muscle bleeding or oral bleeding	20–40	Repeat every 12 to 24 hours. At least 1 day, until the bleeding episode as indicated by pain is resolved or healing is achieved.
More extensive haemarthrosis, muscle bleeding or haematoma	30–60	Repeat infusion every 12 to 24 hours for 3 to 4 days or more until pain and acute disability are resolved.
Life threatening haemorrhages	60–100	Repeat infusion every 8 to 24 hours until threat is resolved.
Surgery
Minor surgery including tooth extraction	30–60	Every 24 hours, at least 1 day, until healing is achieved.
Major surgery	80–100 (pre- and postoperative)	Repeat infusion every 8–24 hours until adequate wound healing, then therapy for at least another 7 days to maintain a factor VIII activity of 30% to 60% (IU/dL).

4. Peel back the paper cover from the vial adapter package. Do not remove the adapter from the package.

5. Place the powder vial on an even surface and hold it. Take the adapter package and place the vial adapter over the centre of the rubber stopper of the powder vial. Press down firmly the adapter package until the adapter spike penetrates the rubber stopper. The adapter snaps to the vial when done.

6. Peel back the paper cover from the pre-filled syringe package. Hold the plunger rod at the end and do not touch the shaft. Attach the threaded end of the plunger rod to the solvent syringe plunger. Turn the plunger rod clockwise until a slight resistance is felt.

INSTRUCTIONS FOR PREPARATION AND ADMINISTRATION

1. Allow the solvent syringe (water for injections) and the powder in the closed vial to reach room temperature. You can do this by holding them in your hands until they feel as warm as your hands. Do not use any other way to heat the vial and pre-filled syringe. This temperature should be maintained during reconstitution.
2. Remove the plastic flip-off cap from the powder vial to expose the central portions of the rubber stopper. Do not remove the gray stopper or metal ring around the top of the vial.
7. Break off the tamper-proof plastic tip from the solvent syringe by snapping the perforation of the cap. Do not touch the inside of the cap or the syringe tip. In case the solution is not used immediately close the filled syringe with the tamperproof plastic tip for storage.
8. Remove the adapter packaging and discard.
9. Firmly connect the solvent syringe to the vial adapter by turning clockwise until resistance is felt.
10. Slowly inject all solvent into the powder vial by pressing down the plunger rod.
11. Without removing the syringe, gently move or swirl the vial in circles a few times to dissolve the powder. Do not shake. Wait until all the powder dissolves completely.
12. Visually inspect the final solution for particles before administration. The solution should be clear and colourless, practically free from visible particles. Do not use solutions that are cloudy or have deposits.
13. Turn the vial attached to the syringe upside down, and slowly draw the final solution into the syringe. Make sure that the entire content of the vial is transferred to the syringe.
14. Detach the filled syringe from the vial adapter by turning counter clockwise and discard the empty vial.
15. The solution is now prepared for immediate use. Do not refrigerate.
16. Clean the chosen injection site with one of the provided alcohol swabs.
17. Attach the provided infusion set to the syringe.

Insert the needle of the infusion set into the chosen vein. If you have used a tourniquet to make the vein easier to see, this tourniquet should be released before you start injecting the solution. No blood must flow into the syringe due to the risk of formation of fibrin clots.

18. Inject the solution into the vein at a slow speed, not faster than 4 mL per minute.
