1. What EMOCLOT is and what it is used for

EMOCLOT is a highly purified concentrate of coagulation factor VIII obtained from human plasma. Factor VIII is a protein with antihemorrhagic activity.
EMOCLOT is used:

• for the treatment and prevention of bleeding in patients with congenital factor VIII deficiency (hemophilia A);
• for the treatment of bleeding in patients with acquired factor VIII deficiency;
• for the treatment of patients with hemophilia with inhibitors to factor VIII.

This medicinal product does not contain a pharmacologically effective amount of von Willebrand factor, and therefore it is not indicated for the treatment of von Willebrand's disease.

2. Before you use EMOCLOT

When not to use EMOCLOT

if you are allergic to human factor VIII or any of the other ingredients of this medicinal product (listed in section 6).

Warnings and precautions

Before starting treatment with EMOCLOT, you should discuss it with your doctor.
Hypersensitivity
It is possible to develop allergic reactions to EMOCLOT.
EMOCLOT contains trace amounts of human proteins other than factor VIII. Patients should be informed about the early signs of hypersensitivity reactions. Administration of the medicinal product should be stopped immediately if the patient experiences any of the following symptoms that may indicate an allergic reaction: rash, generalized urticaria, chest tightness, wheezing, low blood pressure, and acute allergic reaction.
In case of shock, administration should be stopped immediately and shock treatment should be initiated according to the guidelines.
Inhibitors
The development of inhibitors (antibodies) is a known complication that can occur during treatment with all factor VIII products. These inhibitors, especially at high levels, disrupt proper treatment, and the patient will be closely monitored for the development of these inhibitors. If the patient's bleeding is not properly controlled after using Emoclot, you should immediately tell your doctor.
Cardiovascular events
In patients with existing risk factors for cardiovascular diseases, substitution therapy with factor VIII may increase the risk of cardiovascular disorders.
Complications related to catheter administration
In case of need to use a device for central venous administration, the risk of complications associated with its use should be considered, including local infection, bacteremia, and thrombosis at the catheter insertion site.
Viral safety
For medicinal products manufactured from human blood or plasma, appropriate measures are taken to prevent the transmission of infections to patients. These include:

• careful selection of blood and plasma donors to ensure that individuals at risk of infection are excluded;
• testing of each donation and plasma pool (a collection of donations) for viruses and infections.
• incorporation into the manufacturing process of procedures that inactivate or remove viruses. Despite these precautions, it is not possible to completely exclude the possibility of transmitting infectious agents through a medicinal product prepared from human blood or plasma. This also applies to unknown or newly discovered viruses and other pathogens. The measures taken are considered effective against enveloped viruses such as HIV, HBV, and HCV, and non-enveloped viruses such as HAV. These measures may have limited effectiveness against non-enveloped viruses, such as parvovirus B19. Infection with parvovirus B19 can be harmful to pregnant women (fetal infection) and to patients with immune deficiency or certain types of anemia (e.g., sickle cell anemia or hemolytic anemia).

It is strongly recommended that every time EMOCLOT is administered to a patient, the name and batch number of the product should be recorded in order to facilitate the tracing of the batch should it be necessary in the future.
For patients receiving factor VIII regularly or repeatedly, appropriate vaccinations (against hepatitis A and B) should be considered.
Children and adolescents
The above warnings and precautions apply to both adults and children.
More information can be found at the end of the leaflet in the section intended for healthcare professionals.

EMOCLOT and other medicines

Tell your doctor or pharmacist about all the medicines you are taking or have recently taken, as well as any medicines you plan to take.
No interactions between factor VIII and other medicines have been reported.
There are no special data on the use in children.

Pregnancy and breastfeeding

• If you are pregnant or breastfeeding, think you may be pregnant, or plan to have a child, ask your doctor for advice before using this medicine.
• No studies on the effects of factor VIII on reproduction in animals have been conducted. Due to the rare occurrence of hemophilia A in women, there is a lack of experience with the use of factor VIII in pregnant and breastfeeding women. Therefore, factor VIII may be used during pregnancy and lactation only if strictly necessary.

Driving and using machines

EMOCLOT has no influence on the ability to drive and use machines.

EMOCLOT contains sodium

The medicinal product contains up to 41 mg of sodium (the main component of common salt) per 10 ml vial. This corresponds to 2.05% of the maximum recommended daily intake of sodium in the diet for adults.

3. How to use EMOCLOT

This medicinal product should always be used as directed by your doctor. Treatment should be initiated under the supervision of a doctor experienced in the treatment of hemophilia.

Recommended dose

Dosing and duration of substitution therapy depend on the degree of factor VIII deficiency, the location and extent of bleeding, and the patient's clinical condition.
On-demand treatment
When determining the required dose and frequency of administration, the clinical efficacy in the individual case should be taken into account.
Prophylaxis
In long-term prophylaxis of bleeding in patients with severe hemophilia A, doses of 20 to 40 IU of factor VIII per kg of body weight are usually administered at intervals of 2 to 3 days.
In some cases, especially in younger patients, it may be necessary to administer the medicinal product at shorter intervals or in higher doses.
Patients treated with factor VIII should be closely monitored for the development of inhibitors.
During treatment, the appropriate level of factor VIII should be evaluated in order to adjust the dosing and frequency of infusions. Especially in the case of major surgical procedures, precise monitoring of substitution therapy using coagulation tests (factor VIII activity in plasma) is necessary to determine the exact dosing and frequency of infusions.
Children and adolescents
EMOCLOT is not recommended for use in children under 12 years of age due to insufficient data on safety and efficacy.
More information on dosing and duration of treatment can be found at the end of this leaflet in the section intended for doctors and healthcare professionals.

Method of administration

The medicinal product is administered intravenously by injection or slow infusion.
In the case of intravenous injection, it is recommended to maintain the administration time from 3 to 5 minutes, checking the patient's heart rate and stopping the administration or reducing the infusion rate if the heart rate increases.
The infusion rate should be determined individually for each patient.
Only the enclosed injection or infusion sets should be used, as the adsorption of human factor VIII onto the inner surfaces of some injection or infusion sets may be the cause of therapeutic failure.
Incompatibilities: due to the lack of compatibility studies of this medicinal product, it must not be mixed with other medicinal products.

Overdose of EMOCLOT

There are no known symptoms of overdose of human coagulation factor VIII.
In case of accidental ingestion or overdose of EMOCLOT, you should immediately go to the nearest hospital.
If you have any further questions on the use of this medicinal product, ask your doctor or pharmacist.

4. Possible side effects

Like all medicines, this medicine can cause side effects, although not everybody gets them.
If you experience any of the following side effects, you should immediately inform your doctor or the nearest hospital:

• Severe allergic reactions (hypersensitivity): rapidly progressing swelling of the skin and mucous membranes around the mouth and face (angioedema). This reaction has been rarely observed, but in some cases, it may worsen to an acute allergic reaction, including anaphylactic shock.
• In patients with hemophilia A, neutralizing antibodies (inhibitors) to factor VIII may develop, which is manifested by a poor clinical response to treatment. In these cases, consultation with a specialized hemophilia treatment center is recommended.

Other possible side effects:

• Other allergic reactions (hypersensitivity) may include:
• burning and pain at the injection site;
• chills, sudden flushing of the face, generalized urticaria (occurring on the skin all over the body), rash;
• headache
• low blood pressure (hypotension), anxiety, rapid heartbeat (tachycardia), chest tightness, wheezing;
• drowsiness (lethargy);
• nausea, vomiting;
• tingling sensation. The above side effects have been observed in rare cases after administration of factor VIII products, but in some cases, they may worsen to acute allergic reactions, including anaphylactic shock.

The frequency of side effects after the marketing authorization of Emoclot is unknown, which means that it cannot be determined from the available data.
Fever has also been observed.
In children who have not been previously treated with factor VIII products, inhibitory antibodies (see section 2) may develop 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 not very common (less than 1 in 100 patients). If this happens, the medicines may stop working properly in the patient, and persistent bleeding may occur. If this happens, you should immediately contact your doctor.
Additional side effects in children
Although there are no special data on the pediatric population, several published studies on efficacy and safety have not shown significant differences between adults and children with the same condition.

Information intended for healthcare professionals only:

Monitoring of treatment
During treatment, the appropriate level of factor VIII should be evaluated in order to adjust the dosing and frequency of infusions. The response to factor VIII may vary in individual patients in terms of half-life and recovery levels. Dosing based on body weight may need to be adjusted in patients who are underweight or overweight.
Especially in the case of major surgical procedures, precise monitoring of substitution therapy through coagulation tests (factor VIII activity in plasma) is necessary to determine the exact dosing and frequency of infusions.
The above warnings and precautions apply to both adults and children.
More information can be found below.

Dosing

Dosing and duration of substitution therapy depend on the degree of factor VIII deficiency, the location and extent of bleeding, and the patient's clinical condition.
The number of units of factor VIII administered is expressed in international units (IU) corresponding to the current WHO standards for factor VIII products. Factor VIII activity in plasma is expressed either as a percentage (relative to normal human plasma) or in international units (relative to international standards for factor VIII in plasma).
One international unit (IU) of factor VIII activity is equivalent to the amount of factor VIII present in 1 ml of plasma from a healthy individual.
On-demand treatment
The calculation of the required dose of factor VIII is based on empirical data demonstrating that 1 IU of factor VIII per kg of body weight increases the factor VIII activity in plasma by 1.5% to 2%.
The required dose is determined according to the following formula:
Required number of units = body weight [kg] x desired increase in factor VIII activity [%] x 0.4
When determining the required dose and frequency of administration, the clinical efficacy in the individual case should always be taken into account.
In the following cases of bleeding, factor VIII activity in plasma should not fall below the specified value (% of normal or IU/ml).

Severity of bleeding/Surgical procedure

Frequency of dosing (hours)/

Duration of treatment (days)

Required factor VIII level (%)(IU/ml)

• 20 - 40 Repeat infusions every 12 to 24 hours for at least 1 day, until bleeding has stopped, as assessed by the disappearance of pain or healing of the wound. More severe bleeding into a joint, bleeding into muscles or hematoma
• 30 - 60 Repeat every 12-24 hours for 3-4 days or longer, until pain or acute disability has resolved. Life-threatening bleeding
• 60 - 100 Repeat every 8 to 24 hours until the risk has resolved Surgical procedures: Minor surgical procedures, including tooth extraction
• 30 – 60 Repeat infusions every 24 hours for at least 1 day, until healing. Major surgical procedures
• 80 – 100 (before and after surgery) Repeat every 8 to 24 hours until wound healing, then for at least 7 days to maintain factor VIII activity at a level of 30% to 60% (30 IU/ml - 60 IU/ml).

Prophylaxis
In long-term prophylaxis of bleeding in patients with severe hemophilia A, doses of 20 to 40 IU of factor VIII per kg of body weight are usually administered at intervals of 2 to 3 days.
In some cases, especially in younger patients, it may be necessary to administer the medicinal product at shorter intervals or in higher doses.
Children and adolescents
EMOCLOT is not recommended for use in children under 12 years of age due to insufficient data on safety and efficacy. Dosing in adolescents (12-18 years) for each indication is calculated based on body weight.

Method of administration

Administer intravenously by injection or slow infusion.
In the case of intravenous injection, it is recommended to maintain the administration time from 3 to 5 minutes, checking the patient's heart rate and stopping the administration or reducing the infusion rate if the heart rate increases.
The infusion rate should be determined individually for each patient.
Instructions for reconstitution of the medicinal product before administration, see section 3. How to use EMOCLOT.
Inhibitors
The clinical significance of the developed inhibitor will depend on the inhibitor titre, with low-titre inhibitors posing a lower risk of inadequate clinical response than high-titre inhibitors.
Generally, all patients treated with factor VIII products must be closely monitored for the development of inhibitors through clinical observation and laboratory tests. If, despite the use of an adequate dose, it is not possible to achieve the expected level of factor VIII activity in plasma or to control bleeding, a test to assess the presence of factor VIII inhibitors should be performed. In patients with significant inhibitor activity, treatment with factor VIII may be ineffective, and alternative treatment options should be considered. Treatment of such patients should be carried out under the supervision of physicians experienced in the treatment of hemophilia and factor VIII inhibitors.
