What it is and what it is used for

for

ALTUVOCT contains the active substance efanesoctocog alfa, a replacement factor VIII protein. ALTUVOCT is used to treat and prevent bleeding in patients 2 years and above with severe or moderate haemophilia A (the factor VIII blood level is 5% or less). Factor VIII is a protein naturally found in the body and is necessary for the blood to form clots and stop bleeding. In patients with haemophilia A, factor VIII is missing or not working properly. ALTUVOCT replaces the deficient or missing factor VIII. ALTUVOCT increases factor VIII levels in the blood, helping blood to form clots at the site of bleeding which temporarily corrects the bleeding tendency. 2.

What you need to know before you take it

e ALTUVOCT

Do not use ALTUVOCT if you are allergic to efanesoctocog alfa or any of the other ingredients of this medicine (listed in section 6).

1

Warnings and precautions Talk to your doctor, pharmacist, or nurse before using ALTUVOCT. •

There is a rare chance that you may experience hypersensitivity reactions, including anaphylactic reaction (a severe, sudden allergic reaction) to ALTUVOCT. Signs of allergic reactions may include generalised itching, hives, tightness of the chest, difficulty in breathing, and low blood pressure. If any of these symptoms occur, stop the injection immediately and contact your doctor.

•

Talk to your doctor if you think that your or your child's bleeding is not being controlled with the dose you receive, as there can be several reasons for this. Some people using this medicine can develop antibodies to factor VIII (also known as factor VIII inhibitors). The formation of factor VIII inhibitors is a known complication that can occur during treatment with all factor VIII medicines. These inhibitors, especially at high levels, stop the treatment from working properly and you or your child will be monitored carefully for the development of these inhibitors.

Cardiovascular events If you have heart disease or are at risk for heart disease, take special care when using factor VIII medicines and talk to your doctor. 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. Other medicines and ALTUVOCT Tell your doctor if you are using, have recently used or might use any other medicines. Pregnancy and breastfeeding If you are pregnant or breastfeeding, think that you may be pregnant or are planning to have a baby, ask your doctor for advice before using this medicine. Driving and using machines ALTUVOCT has no or negligible influence on your ability to drive and use machines. 3.

How to use ALTUVOCT

Treatment with ALTUVOCT will be started by a doctor who is experienced in the care of patients with haemophilia A. ALTUVOCT is given as an injection into a vein. After proper training in the correct injection technique, patients or caregivers may be able to administer ALTUVOCT at home. Your doctor will calculate your dose (in International Units or "IU") for you. This will depend on your weight and whether it is used for prevention or treatment of bleeding. Always use this medicine exactly as your doctor has told you. Check with your doctor, pharmacist or nurse if you are not sure. Keeping a record Each time you use ALTUVOCT, record the date, the name of the medicine and the batch number. Prevention of bleeding The usual dose of ALTUVOCT is 50 international units (IU) per kg of body weight. The injection is given weekly.

2

Treatment of bleeding The dose of ALTUVOCT is 50 international units (IU) per kg of body weight. The dose and frequency may be adjusted depending on the severity and location of the bleeding. Use in children and adolescents ALTUVOCT can be used in children 2 years and above, the dose recommendation is the same as in adults.

How to take it

ALTUVOCT is given as an injection into a vein. See 'Instructions on how to use ALTUVOCT' for more information. If you use more ALTUVOCT than you should Tell your doctor as soon as possible. You should always use ALTUVOCT exactly as your doctor has told you. Check with your doctor, pharmacist or nurse if you are not sure. If you forget to use ALTUVOCT Do not inject a double dose to make up for a forgotten dose. Inject your dose as soon as you remember and then resume your normal dosing schedule. If you are not sure what to do, ask your doctor, pharmacist, or nurse. If you stop using ALTUVOCT If you stop using ALTUVOCT you may no longer be protected against bleeding or a current bleed may not stop. Do not stop using ALTUVOCT without talking to 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 hypersensitivity reactions, including anaphylactic reaction occurs, the injection must be stopped immediately, and you must contact your doctor right away. Symptoms of hypersensitivity reactions/ anaphylactic reaction include: • • • • • • • •

Swelling of the face rash generalised itching hives tightness of the chest difficulty breathing burning and stinging at the injection site chills

• • • • • • • •

flushing headache low blood pressure general feeling of being unwell nausea restlessness and fast heartbeat feeling dizzy loss of consciousness

Risk of formation of inhibitors For children not previously treated with factor VIII medicines, formation of inhibitor antibodies (see section 2) is very common (may affect 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 (may affect up to 1 in 100 patients). If you or your child develop inhibitor antibodies, the medicine may stop working properly and you or your child may experience persistent bleeding. If this happens, you should contact your doctor immediately.

Technical information intended for healthcare professionals (doctors and pharmacists). The Summary of Product Characteristics (SmPC) is the official document approved by the MHRA/EMA. It does not replace the patient leaflet or a doctor’s advice.

4.1. Therapeutic indications

Treatment and prophylaxis of bleeding in patients 2 years and above with severe or moderate haemophilia A (≤ 5% endogenous plasma factor VIII activity).

4.2. Posology and method of administration

Treatment should be under the supervision of a physician experienced in the treatment of haemophilia.

After proper training in the correct injection technique (see section 6.6 and package leaflet), a patient may self-inject ALTUVOCT, or the patient's caregiver may administer it, if their physician determines that it is appropriate.

Treatment monitoring

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. Monitoring of plasma factor VIII activity levels for the purpose of dose adjustment is usually not necessary during routine prophylaxis. In case of major surgery or life-threatening bleeds, determination of plasma factor VIII activity levels is required to guide the dose and frequency of repeated injections.

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.

It is recommended to use a validated one-stage clotting assay to determine plasma factor VIII activity of ALTUVOCT. Throughout the clinical development an Actin- FSL-based one-stage clotting assay was used.

According to the findings of a comparative analysis of clinical study samples, results obtained using a chromogenic assay should be divided by 2.5 to approximate the patient's plasma factor VIII activity (see section 4.4). In addition, a field study comparing different aPTT reagents indicated approximately 2.5-fold higher plasma factor VIII activity levels when using Actin-FS instead of Actin-FSL in the one-stage clotting assay and approximately 30% lower results when using SynthASil.

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 are 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 IU of factor VIII activity is equivalent to that quantity of factor VIII in one mL of normal human plasma.

For the dose of 50 IU factor VIII per kg body weight, the expected in vivo plasma recovery in factor VIII level expressed as IU/dL (or % of normal) is estimated using the following formula:

Estimated increment of factor VIII (IU/dL or % of normal) = 50 IU/kg x 2 (IU/dL per IU/kg)

On demand treatment

ALTUVOCT dosing for the on-demand treatment, control of bleeding episodes and perioperative management is provided in Table 1.

Degree of haemorrhage/ Type of surgical procedure

Recommended dose

Additional information

Haemorrhage

Early haemarthrosis, muscle bleeding or oral bleeding

Single dose of 50 IU/kg

For minor and moderate bleeding episodes occurring within 2 to 3 days after a prophylactic dose, a lower dose of 30 IU/kg dose may be used.

An additional dose of 30 or 50 IU/kg after 2 to 3 days may be considered.

More extensive haemarthrosis, muscle bleeding or haematoma

Single dose of 50 IU/kg

Additional doses of 30 or 50 IU/kg every 2 to 3 days may be considered until bleeding is resolved.

Life threatening haemorrhages

Single dose of 50 IU/kg

Additional doses of 30 or 50 IU/kg every 2 to 3 days may be administered until the threat is resolved.

Surgery

Minor surgery including tooth extraction

Single dose of 50 IU/kg

An additional dose of 30 or 50 IU/kg after 2 to 3 days may be considered.

Major surgery

Single dose of 50 IU/kg

Additional doses of 30 or 50 IU/kg every 2 to 3 days may be administered as clinically needed until adequate wound healing is achieved.

For resumption of prophylaxis (if applicable) after treatment of a bleed, it is recommended to allow an interval of at least 72 hours between the last 50 IU/kg dose for treatment of a bleed and resuming prophylaxis dosing. Thereafter, prophylaxis can be continued as usual on the patient's regular dosing schedule.

Prophylaxis

The recommended dosing for routine prophylaxis for adults and children is 50 IU/kg of ALTUVOCT administered once weekly.

Special populations

Elderly

There is limited experience in patients ≥ 65 years. The dosing recommendations are the same as for patients < 65 years.

Paediatric population

The dosing recommendations are the same as for adults. There is limited data in paediatric patients < 2 years of age.

ALTUVOCT should not be used in children below 2 years of age.

Method of administration

Intravenous use.

The entire ALTUVOCT dose should be injected intravenously over 1 to 10 minutes, based on the patient's comfort level.

For instructions on dilution of the medicinal product before administration, see section 6.6.

4.3. Contraindications

Hypersensitivity to the active substance or to any of the excipients listed in section 6.1.

4.4. Special warnings and precautions for use

Traceability

In order to improve the traceability of biological medicinal products, the name and the batch number of the administered product should be clearly recorded.

Hypersensitivity

Allergic type hypersensitivity reactions, including anaphylactic reactions have been observed with ALTUVOCT. 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, itching, nausea, vomiting, 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 pro-coagulant 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.

The clinical relevance of inhibitor development will depend on the titre of the inhibitor, with low titres 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 levels of plasma factor VIII activity 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 inhibitors, factor VIII therapy may not be effective. In patients with high titre inhibitors, 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.

Monitoring laboratory tests

If the chromogenic assay or the one-stage clotting assay with Actin-FS reagent are used, divide the result by 2.5 to approximate the patient's plasma factor VIII activity level (see section 4.2). Of note, this conversion factor only represents an estimate (mean chromogenic assay/one-stage clotting assay Actin-FSL ratio: 2.53; SD: 1.54; Q1: 1.98; Q3: 2.96; N=3 353).

Cardiovascular events

In patients with existing cardiovascular risk factors, substitution therapy with factor VIII 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.

4.5. Interaction with other medicinal products and other forms of interaction

No interactions of human coagulation factor VIII (rDNA) products with other medicinal products have been reported.

No interaction studies have been performed.

4.6. Fertility, pregnancy and lactation

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 lactation only if clearly indicated.

4.7. Effects on ability to drive and use machines

ALTUVOCT has no or negligible influence on the ability to drive and use machines.

4.8. Undesirable effects

Summary of the safety profile

Hypersensitivity or allergic reactions (which may include angioedema, burning and stinging at the injection site, chills, flushing, generalised urticaria, headache, hives, hypotension, lethargy, nausea, restlessness, tachycardia, tightness of the chest, tingling, vomiting, wheezing) have been observed rarely 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 ALTUVOCT (see section 5.1). If such inhibitors occur, the condition may 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 2 presented below is according to the MedDRA system organ classification (SOC and Preferred Term Level). Frequencies of adverse reactions are based on Phase 3 clinical studies in 277 previously treated patients (PTPs) with severe haemophilia A, of which 161 (58.2%) were adults (18 years of age and older), 37 (13.4%) were adolescents (12 to < 18 years of age), and 79 (28.5%) were children under the age of 12 years.

Adverse drug reactions (ADRs) (summarized in Table 2) were reported in 111 (40.1%) of the 277 subjects treated in clinical studies with routine prophylaxis or on-demand therapy or reported in post -marketing setting.

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.
