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.

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 important to keep a record of the batch number of your Nuwiq. So, every time you get a new package of Nuwiq, note down the date and the batch number (which is on the packaging after Lot) and keep this information in a safe place. 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 18.4 mg sodium (main component of cooking/table salt) in each vial. This is equivalent to 0.92 % of the recommended maximum daily dietary intake of sodium for an adult.

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.
Like all medicines, this medicine can cause side effects, although not everybody gets them. Please stop using this medicine immediately and seek urgent medical advice if: you notice symptoms of allergic reactions Allergic reactions may include rash, hives, urticaria (itchy rash), including generalized urticaria, swelling of lips and tongue, shortness of breath, wheezing, tightness of the chest, vomiting, restlessness, low blood pressure, and dizziness. These symptoms can be early symptoms of an anaphylactic shock. If severe, sudden allergic reactions (anaphylactic) occur (very rare: may affect up to 1 in 10,000 people), the injection must be stopped immediately, and you must contact your doctor right away. Severe symptoms require prompt emergency treatment. you notice that the medicine stops working properly (bleeding is not stopped or becomes frequent) 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. 20240515_pil_139_UK_03.02

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.
3. Wipe the top of the vial with an alcohol swab. Allow the alcohol to dry. 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.

Treatment and prophylaxis of bleeding in patients with haemophilia A (congenital factor VIII deficiency).
Nuwiq can be used for all age groups.
Treatment should be under the supervision of a physician experienced in the treatment of haemophilia.
Treatment monitoring
During the course of treatment, appropriate determination of factor VIII levels is advised to guide the dose to be administered and the frequency of repeated infusions. Individual patients may vary in their response to factor VIII, demonstrating different half-lives and recoveries. Dose based on bodyweight may require adjustment in underweight or overweight patients. In the case of major surgical interventions in particular, precise monitoring of the substitution therapy by means of coagulation analysis (plasma factor VIII activity) is indispensable.
When using an in vitro thromboplastin time (aPTT)-based one stage clotting assay for determining factor VIII activity in patients' blood samples, plasma factor VIII activity results can be significantly affected by both the type of aPTT reagent and the reference standard used in the assay. Also there can be significant discrepancies between assay results obtained by aPTT-based one stage clotting assay and the chromogenic assay according to Ph. Eur. This is of importance particularly when changing the laboratory and/or reagents used in the assay.
Posology
The dose and duration of the substitution therapy depend on the severity of the factor VIII deficiency, on the location and extent of the bleeding and on the patient's clinical condition.
The number of units of factor VIII administered is expressed in International Units (IU), which is related to the current WHO concentrate standard for factor VIII products. Factor VIII activity in plasma is expressed either as a percentage (relative to normal human plasma) or preferably in International Units (relative to an International Standard for factor VIII in plasma).
One International Unit (IU) of factor VIII activity is equivalent to the quantity of factor VIII in one mL of normal human plasma.
On-demand treatment
The calculation of the required dose of factor VIII is based on the empirical finding that 1 International Unit (IU) factor VIII per kg body weight raises the plasma factor VIII activity by approximately 2% of normal activity or 2 IU/dL. The required dose is determined using the following formula:
Required units = body weight (kg) x desired factor VIII rise (%) (IU/dL) x 0.5 (IU/kg per IU/dL)
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

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).
Prophylaxis
For long-term prophylaxis against bleeding in patients with severe haemophilia A, the usual doses are 20 to 40 IU of factor VIII per kg body weight at intervals of 2 to 3 days. The regimen may be adjusted based on patient response.
In some cases, especially in younger patients, shorter dose intervals or higher doses may be necessary.
Paediatric population
The posology is the same in adults and children and adolescents, however, shorter dose intervals or higher doses may be necessary for children and adolescents. Currently available data are described in sections 4.8, 5.1 and 5.2.
Method of administration
Nuwiq is for intravenous use.
It is recommended that not more than 4 mL per minute be administered.
For instructions on reconstitution of the medicinal product before administration, see section 6.6.
Hypersensitivity to the active substance or to any of the excipients listed in section 6.1.
Traceability
In order to improve traceability of biological medicinal products, the name and the batch number of the administered product should be clearly recorded.
Hypersensitivity
As with any intravenous protein product, allergic type hypersensitivity reactions are possible. Nuwiq contains traces of human host cell proteins other than factor VIII. If symptoms of hypersensitivity occur, patients should be advised to discontinue use of the medicinal product immediately and contact their physician. Patients should be informed of the early signs of hypersensitivity reactions including hives, generalised urticaria, tightness of the chest, wheezing, hypotension, and anaphylaxis.
In case of shock, standard medical treatment for shock should be implemented.
Inhibitors
The formation of neutralising antibodies (inhibitors) to factor VIII is a known complication in the management of individuals with haemophilia A. These inhibitors are usually IgG immunoglobulins directed against the factor VIII procoagulant activity, which are quantified in Bethesda Units (BU) per mL of plasma using the modified assay. The risk of developing inhibitors is correlated to the severity of the disease as well as the exposure to factor VIII, this risk being highest within the first 50 exposure days but continues throughout life although the risk is uncommon.
Cases of recurrent inhibitor (low titre) have been observed after switching from one factor VIII product to another in previously treated patients with more than 100 exposure days who have a previous history of inhibitor development. Therefore, it is recommended to monitor all patients carefully for inhibitor occurrence following any product switch.
The clinical relevance of inhibitor development will depend on the titre of the inhibitor, with low titre inhibitors which are transiently present or remain consistently low titre posing less of a risk of insufficient clinical response than high titre inhibitors.
In general, all patients treated with coagulation factor VIII products should be carefully monitored for the development of inhibitors by appropriate clinical observations and laboratory tests. If the expected factor VIII activity plasma levels are not attained, or if bleeding is not controlled with an appropriate dose, testing for factor VIII inhibitor presence should be performed. In patients with high levels of inhibitor, factor VIII therapy may not be effective and other therapeutic options should be considered. Management of such patients should be directed by physicians with experience in the care of haemophilia and factor VIII inhibitors.
Cardiovascular events
In patients with existing cardiovascular risk factors, substitution therapy with FVIII may increase the cardiovascular risk.
Catheter-related complications
If a central venous access device (CVAD) is required, risk of CVAD-related complications including local infections, bacteraemia and catheter site thrombosis should be considered.
Paediatric population
The listed warnings and precautions apply both to adults and children and adolescents.
Excipient related considerations (sodium content)
This medicinal product contains 18.4 mg sodium per vial, equivalent to 0.92 % of the WHO recommended maximum daily intake of 2 g sodium for an adult.
No interaction studies have been performed with Nuwiq.
Animal reproduction studies have not been conducted with factor VIII.
Based on the rare occurrence of haemophilia A in women, experience regarding the use of factor VIII during pregnancy and breast feeding is not available. Therefore, factor VIII should be used during pregnancy and breast-feeding only if clearly indicated. There are no fertility data available.
Nuwiq has no influence on the ability to drive and use machines.
Summary of the safety profile
Hypersensitivity or allergic reactions (which may include angiooedema, burning and stinging at the infusion site, chills, flushing, headache, hives, hypotension, lethargy, nausea, rash, restlessness, tachycardia, tightness of the chest, tingling, urticaria, including generalised urticaria, vomiting, wheezing) have rarely been observed with FVIII preparations and may in some cases progress to severe anaphylaxis (including shock).
Development of neutralising antibodies (inhibitors) may occur in patients with haemophilia A treated with factor VIII, including with Nuwiq. If such inhibitors occur, the condition will manifest itself as an insufficient clinical response. In such cases, it is recommended that a specialised haemophilia centre be contacted.
Tabulated list of adverse reactions
Table 1 presented below is according to the MedDRA system organ classification (SOC and Preferred Term Level). Frequencies are based on reports from clinical trials with a total of 355 unique subjects with severe haemophilia A, of which 247 were previously treated patients (PTPs) and 108 were previously untreated patients (PUPs).
Frequencies have been evaluated according to the following convention: very common (≥1/10); common (≥1/100 to <1/10); uncommon (≥1/1,000 to <1/100); rare (≥1/10,000 to <1/1,000); very rare (<1/10,000), not known (cannot be estimated from the available data).
Within each frequency grouping, adverse reactions are presented in order of decreasing seriousness.

Description of selected adverse reactions
A non-neutralizing anti-factor VIII antibody was detected in one adult patient (see Table 1). The sample was tested by the central laboratory at eight dilutions. The result was positive only at dilution factor 1 and the antibody titre was very low. Inhibitory activity, as measured by the modified Bethesda assay, was not detected in this patient. Clinical efficacy and in vivo recovery of Nuwiq was not affected in this patient.
Paediatric population
Frequency, type and severity of adverse reactions in children and adolescents are assumed to be the same as in adults.
Reporting of suspected adverse reactions
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the national reporting system.
