What it is and what it is used for

for

VEYVONDI contains the active substance vonicog alfa, which is a recombinant human von Willebrand factor (rVWF). It behaves in the same way as natural human von Willebrand factor (VWF) in the body. VWF is the carrier molecule for coagulation factor VIII and is involved in blood clotting making platelets stick to wounds and so helps to form a blood clot. Lack of VWF increases the tendency to bleed. VEYVONDI is used to prevent and treat bleeding episodes, including bleeding during surgery in adult patients (aged 18 years and older) with von Willebrand disease. It is used when treatment with another medicine, desmopressin, is not effective or cannot be given. VEYVONDI is used to treat bleeding episodes in children aged less than 18 years with von Willebrand disease. It is used when treatment with another medicine, desmopressin, is not effective or cannot be given. Von Willebrand disease is an inherited bleeding disorder caused by the lack or an insufficient amount of von Willebrand factor. In patients with the disease the blood does not clot normally leading to a prolonged bleeding time. Administration of von Willebrand factor (VWF) allows for correction of von Willebrand factor deficiency. 2.

What you need to know before you take it

e VEYVONDI

Do not use VEYVONDI if you are allergic to vonicog 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 unsure about this, ask your doctor. 1

Warnings and precautions Talk to your doctor, pharmacist or nurse before using VEYVONDI. There is a risk that you may experience a hypersensitivity reaction (a severe, sudden allergic reaction) to VEYVONDI. Your doctor should inform you about early signs of severe allergic reactions such as increased heart rate, rash, hives, wheals, generalised itching, swelling of lips and tongue, difficulty in breathing, wheezing, tightness in the chest, fast heartbeat, stuffy nose, red eyes,general feeling of being unwell, and dizziness. These could be early symptoms of a hypersensitivity reaction. If any of these symptoms occur, stop the infusion immediately and contact your doctor. Severe symptoms, including difficulty in breathing and dizziness, require prompt emergency treatment. Patients developing inhibitors Inhibitors (antibodies) against the VWF may occur in some patients receiving the medicine.These inhibitors, especially at high levels, could cause the treatment to stop working properly. You will be monitored carefully for the possibility of having developed these inhibitors. If your bleeding is not controlled with VEYVONDI, tell your doctor immediately. If your plasma VWF or factor VIII fail to reach the expected levels with VEYVONDI based on the test results followed by your doctor, or if bleeding is not adequately controlled, it could be due to the presence of VWF or factor VIII antibodies. This will be checked by your doctor. You might need a higher dose of VEYVONDI, or a higher dose of factor VIII, or even a different medicine to control bleedings. Do not increase the total dose of VEYVONDI to control your bleeding without consulting your doctor. If you have previously been treated with plasma-derived VWF concentrates you may have reduced response to VEYVONDI due to pre-existing antibodies. Your doctor may adjust the dose according to your laboratory results. Thrombolism and embolism There is a risk of occurrence of thrombotic events if you have known clinical or laboratory risk factors. Therefore your doctor will monitor you for early signs of thrombosis. FVIII products may contain varying amounts of VWF. Therefore, any FVIII product that would be administered in combination with VEYVONDI should be a pure FVIII product. If you previously had problems with blood clots or vessel occlusion (thromboembolic complications), tell your doctor immediately. Children and adolescents VEYVONDI is approved for use in children or adolescents below 18 years to treat bleeding episodes; it is not approved for use in children below 18 years to prevent bleeding episodes, and to prevent and treat bleeding during surgery. Other medicines and VEYVONDI Tell your doctor, pharmacist or nurse 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, pharmacist or nurse for advice before taking this medicine. Driving and using machines VEYVONDI is not likely to affect your ability to drive and use machines. VEYVONDI contains sodium 2

This medicine contains 5.2 mg sodium (main component of cooking/table salt) in each 650 IU vial or 10.4 mg sodium in each 1 300 IU vial. This is equivalent to 2.2% of the recommended maximum daily dietary intake of sodium for an adult, assuming 70 kg body weight and 80 IU/kg body weight. This should be taken into consideration if you are on a controlled sodium diet. VEYVONDI contains polysorbate 80 This medicine contains 0.5 mg of polysorbate 80 in each 650 IU vial or 1.0 mg of polysorbate 80 in each 1 300 IU vial, which is equivalent to 0.1 mg/mL. Polysorbates may cause allergic reactions. Tell your doctor if you (or your child) have any known allergies. 3.

How to use VEYVONDI

Your treatment with VEYVONDI will be supervised by a doctor who is experienced in the care of patients with von Willebrand disease. Your doctor will calculate your dose of VEYVONDI (in international units or IU). The dose depends on: body weight, the site of the bleeding, intensity of the bleeding, your clinical condition, the required surgery, the VWF activity levels in your blood after surgery, the severity of your disease. Your doctor may test your blood to make sure that you have adequate levels of von Willebrand factor. This is particularly important if you are having major surgery. Treatment of bleeding episodes Your doctor will calculate the dose that is most appropriate for you or your child, how often you or your child should receive VEYVONDI and for how long. For minor bleeding (e.g. nose-bleed, oral bleeding, menorrhagia), each initial dose is usually 40 to 50 IU/kg and for major bleeding (severe or refractory nose-bleed, menorrhagia, gastrointestinal bleeding, central nervous system trauma, haemarthrosis, or traumatic haemorrhage), each initial dose is 50 to 80 IU/kg. Subsequent doses (as clinically required) are 40 to 50 IU/kg every 8 to 24 hours for minor bleeds as long as deemed clinically necessary and for major bleeds 40 to 60 IU/kg for approximately 2-3 days. If you feel that VEYVONDI is not working well enough, talk to your doctor. Your doctor will perform tests to make sure that you have adequate levels of von Willebrand factor. If you use VEYVONDI at home, your doctor will make sure that you are shown how to infuse it and how much to use. Prevention of bleeding in case of elective surgery For prevention of excessive bleeding your doctor will assess the FVIII:C levels within 3 hours before surgery. If your FVIII level is inadequate your doctor may give you a dose of 40-60 IU/kg VEYVONDI 12-24 hours (pre-operative dose) prior to initiating elective surgery in order to raise FVIII levels to the target level (0.4 IU/mL for minor and at least 0.8 IU/mL for major surgery). Within 1 hour prior to surgery, you will receive a dose of VEYVONDI based on the assessment 3 hours before surgery. The dose depends on VWF and FVIII levels of the patient, the type and severity of the expected bleeding. 3

Prophylaxis treatment The usual starting dose for long term prophylaxis against bleeding episodes is 40 to 60 IU/kg twice weekly. The dose can be adjusted to a maximum of 80 IU/kg one to three times per week, depending on your condition and how well VEYVONDI is working for you. Your doctor will calculate the dose that is most appropriate for you, how often you should receive VEYVONDI and for how long.

How to take it

VEYVONDI is usually infused into a vein (intravenously) by your doctor or nurse. Detailed instructions for reconstitution and administration are given at the end of this package leaflet. Use in children and adolescents VEYVONDI is approved for use in children and adolescents below 18 years to treat bleeding episodes; it is not approved for use in children below 18 years to prevent bleeding episodes, and to prevent and treat bleeding during surgery. If you use more VEYVONDI than you should Always use this medicine exactly as your doctor has told you. Check with your doctor if you are not sure. If you infuse more VEYVONDI than recommended, tell your doctor as soon as possible. There may be a risk of developing blood clots (thrombosis) in case of an accidental high dose. If you forget to use VEYVONDI Do not infuse a double dose to make up for a forgotten dose. Proceed with the next infusion as scheduled and continue as advised by your doctor. If you stop using VEYVONDI Do not stop using VEYVONDI without consulting your doctor. If you have any further questions on the use of this medicine, ask your doctor or pharmacist. 4.

Use plastic syringes with this product because proteins in the product tend to stick to the surface of glass syringes. Do not mix VEYVONDI with other medicinal products except for octocog alfa (ADVATE). Instructions for reconstitution

Steps

1

Remove the caps from the VEYVONDI powder and solvent vials to expose the centre of the rubber stoppers.

2

Disinfect each stopper with a separate sterile alcohol swab (or other suitable sterile solution suggested by your doctor or haemophilia treatment centre) by wiping the stopper for several seconds. Allow the rubber stoppers to dry. Place the vials on a flat surface.

3

Open the Mix2Vial device package by completely peeling away the lid, without touching the inside of the package. Do not remove the Mix2Vial device from the package. Turn the package with the Mix2Vial device upside down and place it over the top of the solvent vial. Firmly insert the blue plastic spike of the device into the centre of the solvent vial stopper by pushing straight down. Grip the package at its edge and lift it off the Mix2Vial device. Be careful not to touch the clear plastic spike. The solvent vial now has the Mix2Vial device connected to it and is ready to be connected to the VEYVONDI vial. To connect the solvent vial to the VEYVONDI vial, turn the solvent vial over and place it on top of the vial containing VEYVONDI powder. Fully insert the clear plastic spike into the VEYVONDI vial stopper by firmly pushing straight down. This should be done right away to keep the liquid free of germs. The solvent will flow into the VEYVONDI vial by vacuum. Check that all the solvent has transferred. Do not use if vacuum has been lost and the solvent does not flow into the VEYVONDI vial.

Disconnect the two sides of the Mix2Vial from each other by holding the clear plastic side of the Mix2Vial device attached to the VEYVONDI vial with one hand and the blue plastic side of the Mix2Vial device attached to the solvent vial with the other hand. Turn the blue plastic side counterclockwise and gently pull the two vials apart. Do not touch the end of the plastic connector attached to the VEYVONDI vial containing the dissolved product. Place the VEYVONDI vial on a flat work surface. Discard the empty solvent vial. Draw air into the empty, sterile disposable plastic syringe by pulling back on the plunger. The amount of air should equal the amount of reconstituted VEYVONDI that you will withdraw from the vial.

9

Leaving the VEYVONDI vial (containing the reconstituted product) on your flat work surface, connect the syringe to the clear plastic connector and turn the syringe clockwise.

10

Hold the vial with one hand and use the other hand to push all the air from the syringe into the vial

11

Flip connected syringe and VEYVONDI vial so the vial is on top. Be sure to keep the syringe plunger pressed in. Draw the VEYVONDI into the syringe by pulling plunger back slowly.

12

Do not push and pull solution back and forth between syringe and vial. Doing so may harm the medicine. When ready to infuse, disconnect the syringe by turning it counterclockwise. Inspect the syringe visually for particulate matter; the solution should be clear and colourless. If flakes or particles are seen, do not use the solution and notify your doctor.

If you need more than one vial of VEYVONDI to make up your dose:

• Leave the syringe attached to the vial until an additional vial is prepared.
• Use the reconstitution steps above (2 to 8) to prepare the additional vial of VEYVONDI using a fresh Mix2Vial for each vial. The contents of two vials may be drawn into a single syringe. NOTE: When pushing air into a second vial of VEYVONDI to be pooled into a syringe, position the vial and connected syringe so that the vial is on top.

Instructions for administration Inspect the prepared solution in the syringe for particulate matter and discolouration prior to administration (the solution should be clear, colourless and free from particles). It is not uncommon for a few flakes or particles to remain in the product vial after reconstitution. The filter included in the Mix2Vial device removes those particles completely. Filtration does not influence dose calculations. The solution in the syringe should not be used if it is cloudy or contains flakes or particles after filtration. 1. Attach the infusion needle to a syringe containing VEYVONDI solution. For comfort, a winged (butterfly) infusion set is preferred. Point the needle up and remove any air bubbles by gently tapping the syringe with your finger and slowly and carefully pushing air out of the syringe and needle. 2. Apply a tourniquet and get the infusion site ready by wiping the skin well with a sterile alcohol swab (or other suitable sterile solution suggested by your doctor or haemophilia treatment centre). 3. Insert the needle into the vein and remove the tourniquet. Slowly infuse VEYVONDI. Do not infuse any faster than 4 mL per minute. Disconnect the empty syringe. If your dose requires multiple syringes, attach and administer each additional syringe of VEYVONDI one at a time. Note: Do not remove butterfly needle until all syringes have been infused and do not touch the Luer port that connects to the syringe. If recombinant factor VIII has been prescribed, administer recombinant factor VIII within 10 minutes after infusion of VEYVONDI has been completed. 4. Take the needle out of the vein and use sterile gauze to put pressure on the infusion site for several minutes. In case large volumes of VEYVONDI are required, it is possible to pool two vials of VEYVONDI together. The contents of each reconstituted product of VEYVONDI can be drawn in a single syringe. However, in these cases the initially reconstituted solution of VEYVONDI should not be diluted any further. The solution should be slowly administered intravenously not exceeding 4 mL/min. Do not recap the needle. Place the needle, syringe, and empty VEYVONDI and solvent vial(s) in a hard-walled sharps container for proper disposal. Do not dispose of these supplies in ordinary household trash. Any unused medicinal product or waste material should be disposed of in accordance with local requirements. ———————————————————————————————————————–9

The following information is intended for healthcare professionals only: Treatment of bleeding episodes (on-demand treatment) in adults and children Dose and frequency must be individualized based on clinical judgment, taking into account of severity of bleeding episode, site of bleeding, patient's medical history, monitoring of appropriate clinical and laboratory measures (both VWF:RCo and FVIII:C levels). Start of treatment The first dose of VEYVONDI should be 40 to 80 IU/kg body weight. Replacement levels of VWF:RCo > 0.6 IU/mL (60%) and FVIII:C > 0.4 IU/mL (40%) should be achieved. Dosing guidelines for treatment of minor and major haemorrhages are provided in Table 1. VEYVONDI should be administered with recombinant factor VIII if the FVIII:C levels are <40%, or are unknown, to control bleeding. The rFVIII dose should be calculated according to the difference between the patient's baseline plasma FVIII:C level, and the desired peak FVIII:C level to achieve an appropriate plasma FVIII:C level based on the approximate mean recovery of 0.02 (IU/mL)/(IU/kg). The complete dose of VEYVONDI should be administered followed by rFVIII within 10 minutes. Calculating dose VEYVONDI dose [IU] = dose [IU/kg] x body weight [kg] Subsequent infusions A subsequent dose of 40 IU to 60 IU/kg of VEYVONDI should be infused every 8 to 24 hours as per the dosing ranges in Table 1, or as long as clinically appropriate. In major bleeding episodes, maintain trough levels of VWF:RCo greater than 50% for as long as deemed necessary. Table 1. Dosing recommendations for the treatment of minor and major haemorrhages Haemorrhage Minor (e.g. epistaxis, oral bleeding, menorrhagia) Majorb (e.g. severe or refractory epistaxis, menorrhagia, gastrointestinal bleeding, central nervous system trauma, haemarthrosis, or traumatic haemorrhage)

If rFVIII is administered, see rFVIII package insert for reconstitution and administration instructions. A bleed could be considered major if red blood cell transfusion is either required or potentially indicated or if bleeding occurs in a critical anatomical site (e.g., intracranial or gastrointestinal haemorrhage). a

b

Prevention of bleeding/haemorrhage and treatment in case of elective surgery in adults Assess FVIII:C levels prior to initiation of any surgical procedure. The recommended minimum target levels are 0.4 IU/mL for minor and oral surgery and 0.8 IU/mL for major surgery. 10

To ensure pre-operative endogenous FVIII levels of at least 0.4 IU/mL for minor and oral and 0.8 IU/mL for major surgery, a dose of 40-60 IU/kg VEYVONDI may be administered 12-24 hours (pre-operative dose) prior to initiating elective surgery. Within 1 hour prior to surgery, patients should receive a dose of VEYVONDI based on the assessment 3 hours before surgery. The dose depends on VWF and FVIII levels of the patient, the type and severity of the bleeding. If the FVIII:C levels are at the recommended target, a dose of VEYVONDI alone should be administered within 1 hour prior to the procedure. If the FVIII:C levels are not at the recommended target levels, rFVIII should be administered in addition to vonicog alfa to raise VWF:RCo and FVIII:C. Please refer to Table 2 for FVIII:C recommended target levels. Table 2. Recommended target peak plasma levels of VWF:RCo and FVIII:C to be achieved prior to surgery for the prevention of excessive bleeding during and after surgery VWF:RCo FVIII:C target Calculation of rVWF dose (to be Type of target peak peak plasma administered within 1 hour prior to surgery plasma level levela surgery) (IU VWF:RCo required) Minor 0.5 – 0.6 IU/mL 0.4 – 0.5 IU/mL ∆b VWF:RCo x BW (kg) /IRc Major 1 IU/mL 0.80 – 1 IU/mL ∆b VWF:RCo x BW (kg) /IRc Additional rFVIII may be required to attain the recommended FVIII:C target peak plasma levels.

If the IR is not available, assume an IR of 0.02 IU/mL per IU/kg. a

During and after surgery After the initiation of the surgical procedure, the VWF:RCo and FVIII:C plasma levels should be monitored and the intra- and post-operative substitution regimen should be individualized according to the pharmacokinetics (PK) results, intensity and duration of the haemostatic challenge, and the institution's standard of care. In general, the frequency of VEYVONDI dosing for post-operative substitution should range from twice a day to every 48 hours. Refer to Table 3 for treatment recommendations for subsequent maintenance doses. Table 3. Recommended target trough plasma levels of VWF: RCo and FVIII:C and minimum duration of treatment for subsequent maintenance doses for the prevention of excessive bleeding after surgery FVIII:C VWF: RCo target trough plasma target trough plasma level Minimum level Frequency of duration Type of After After dosing of surgery Up to 72 Up to 72 72 hours 72 hours treatment hours post hours post post post surgery surgery surgery surgery > Every 12-24 hrs Minor ≥ 0.30 IU/mL 48 hours 0.40 IU/mL / every other day > > > Every 12-24 hrs Major > 0.50 IU/mL 72 hours 0.30 IU/mL 0.50 IU/mL 0.40 IU/mL / every other day Prophylactic treatment in adults For initiation of long-term prophylaxis against bleeds in patients with VWD doses of 40 to 60 IU/kg of VEYVONDI administered twice weekly should be considered. Depending on the patient's condition 11

and clinical response, including breakthrough bleeds, higher doses (not exceeding 80 IU/kg) and/or an increased dose frequency (up to three times per week) may be required. Paediatric population The safety and efficacy of VEYVONDI in children aged less than 18 years have been established for the treatment of haemorrhage. Dosing is based on the same guidelines as for adults and should be adjusted to the clinical condition of the patient, as well as their VWF:RCo and FVIII:C plasma levels. In younger patients, shorter dose intervals or higher doses may be necessary. The safety and efficacy of VEYVONDI for prophylactic treatment or the prevention or treatment of surgical bleeding have not yet been established in children aged less than 18 years. Name and batch number of the medicinal product It is strongly recommended that every time that VEYVONDI is administered to a patient, the name and batch number of the product are recorded in order to maintain a link between the patient and the batch of the product.
