1. What is FEIBA NF and what is it used for

FEIBA NF is a medicine obtained from human plasma, which enables blood clotting in the event of a deficiency or lack of certain clotting factors.
FEIBA NF is used to treat bleeding and prevent bleeding in patients with hemophilia A complicated by the presence of factor VIII inhibitors and hemophilia B complicated by the presence of factor IX inhibitors.
Additionally, FEIBA NF may be used to treat and prevent bleeding in individuals who do not have hemophilia but have acquired inhibitors of factors VIII, IX, and XI.
FEIBA NF is also used in combination with factor VIII concentrate during long-term treatment aimed at completely and permanently eliminating factor VIII inhibitors, to enable regular treatment with factor VIII concentrate, as in patients without inhibitors.
In isolated cases, FEIBA NF has been used in patients with von Willebrand factor inhibitors.

2. Important information before using FEIBA NF

Inform your doctor if you have any allergies.
Inform your doctor if you are on a low-sodium diet.

When not to use FEIBA NF

In the following situations, FEIBA NF should not be used if it is possible to use another treatment:

• if the patient is hypersensitive to the anti-inhibitor coagulant complex or any of the other components of this medicine (listed in section 6).
• if the patient has disseminated intravascular coagulation (DIC, consumption coagulopathy, a life-threatening condition associated with massive blood clotting and the formation of blood clots in blood vessels, leading to a general depletion of clotting factors).
• if the patient has acute thrombosis or embolism (including myocardial infarction).

See "Warnings and precautions" section.

Warnings and precautions

Discuss the use of FEIBA NF with your doctor before starting treatment.
This medicine may cause allergic-type hypersensitivity reactions, including hives, angioedema, gastrointestinal symptoms, bronchospasm, and hypotension; these reactions can be severe and systemic (e.g., anaphylactic reaction with hives and angioedema, bronchospasm, and shock). Other infusion-related reactions, such as chills, fever, and hypertension, have also been reported.
If the first signs or symptoms of infusion-related reactions/hypersensitivity occur (see section 4), administration of this medicine should be discontinued and appropriate medical care should be initiated.
In patients suspected of being hypersensitive to the medicine or any of its components, the doctor will decide to re-administer FEIBA NF only after careful consideration of the risk and expected benefits and (or) when no alternative preventive or alternative therapeutic measures can be expected.
During treatment with FEIBA NF, thromboembolic events, including disseminated intravascular coagulation (DIC), venous thrombosis, pulmonary embolism, myocardial infarction, and stroke, have occurred.
If the first signs or symptoms of thromboembolic events occur (see section 4), the infusion should be discontinued immediately and appropriate diagnostic and therapeutic measures should be initiated.
Some thromboembolic events have occurred with the use of high doses of FEIBA NF or in patients with other risk factors for thromboembolic events, including DIC, advanced atherosclerosis, crush injury, or sepsis. Concomitant use of recombinant factor VIIa may increase the risk of thromboembolic events. In patients with congenital or acquired hemophilia, the possibility of such risk factors should always be considered.
The medicine should be used with caution in patients at risk of DIC, arterial or venous thrombosis.
Cases of thrombotic microangiopathy have been reported in a clinical study of emicizumab, in which patients received FEIBA NF as part of the breakthrough bleeding treatment regimen.
In patients with hemophilia and inhibitors or acquired inhibitors of clotting factors, during treatment with FEIBA NF, there may be an increased tendency to bleeding and an increased risk of thrombosis at the same time.
In the following situations, the use of FEIBA NF is only justified when no response to treatment with the appropriate clotting factor concentrate is expected, e.g., in the case of a high-titer inhibitor and life-threatening bleeding or risk of bleeding (e.g., post-traumatic or post-operative):

• Disseminated intravascular coagulation (DIC).
• Liver damage: due to the delayed elimination of active clotting factors in patients with impaired liver function, there is an increased risk of DIC.
• Coronary heart disease, acute thrombosis, and (or) embolism. See "When not to use FEIBA NF" section.

In the case of medicines produced from human blood or plasma, certain measures are taken to prevent infections in patients. These measures include careful selection of blood and plasma donors to ensure that those who are at risk of transmitting infections are excluded, and testing of individual blood donations and plasma pools for viruses/infections. Manufacturers of these products also include steps in the blood and plasma processing process that are designed to inactivate or remove viruses. Despite these measures, when administering medicines produced from human blood or plasma, it is not possible to completely exclude the possibility of transmitting an infection. This applies to both known and newly discovered viruses or other types of infections.
The measures taken are considered effective against enveloped viruses, such as HIV (which causes AIDS), hepatitis B virus, and hepatitis C virus, as well as non-enveloped hepatitis A virus. The measures taken may have limited value against non-enveloped viruses, such as parvovirus B19. Parvovirus B19 infection can be serious in pregnant women (fetal infection) and for individuals with immune deficiency or increased erythropoiesis (e.g., hemolytic anemia).
In patients receiving regular or repeated factor VIII from human plasma, consideration should be given to appropriate vaccinations (against viral hepatitis A and B).
After administration of high doses of FEIBA NF, a transient increase in passively transferred antibodies against the surface antigen of hepatitis B virus may result in false-positive serological test results.
The medicine contains isoagglutinins, antibodies against red blood cells, which, when passively transferred, may affect the results of serological tests for the presence of antibodies against red blood cells, such as the antiglobulin test (Coombs test).
Each time a dose of FEIBA NF is administered to the patient, the name and batch number of the medicine should be clearly recorded in order to maintain information about the batches used.

FEIBA NF and other medicines

Inform your doctor about all medicines you are currently taking or have recently taken, including those available without a prescription.
No adequate and well-controlled studies have been conducted on the concomitant or sequential use of FEIBA NF and recombinant factor VIIa, fibrinolysis inhibitors, or emicizumab (see "Warnings and precautions").
The possibility of thromboembolic events should be considered when using systemic fibrinolysis inhibitors, such as tranexamic acid and aminocaproic acid, in combination with FEIBA NF. Therefore, fibrinolysis inhibitors should not be used for approximately 6 to 12 hours after administration of FEIBA NF.
Based on available in vitro data and clinical observations, in cases of concomitant use of recombinant factor VIIa, a potential drug interaction cannot be excluded, which may result in a thromboembolic event.
If treatment with FEIBA NF is considered after the patient has received emicizumab, the patient should be closely monitored by the treating physician.
As with all clotting factor products, FEIBA NF should not be mixed with other medicines before administration; this may adversely affect the efficacy and safety of the medicine.
It is recommended to flush the intravenous access line with isotonic sodium chloride solution before and after administration of FEIBA NF.

Pregnancy, breastfeeding, and fertility

The doctor will decide whether FEIBA NF can be used during pregnancy or breastfeeding. Due to the increased risk of thrombosis during pregnancy, FEIBA NF should only be used under close medical supervision and when clearly indicated.
Regarding the risk of parvovirus B19 infection, see "Warnings and precautions" section.

Driving and using machines

No effects on the ability to drive and use machines have been observed.

FEIBA NF contains sodium

The medicine contains 80 mg of sodium (the main component of common salt) in each vial. This corresponds to 4% of the maximum recommended daily intake of sodium in the diet for adults.

3. How to use FEIBA NF

FEIBA NF powder is dissolved in the supplied solvent and administered intravenously.
This medicine should always be used in accordance with the doctor's instructions. In case of doubts, consult a doctor or pharmacist.
Treatment should be initiated and supervised by a doctor experienced in the treatment of clotting disorders.
The doctor will determine the appropriate dose and frequency of administration individually for each patient, taking into account the severity of the clotting disorder, the location and extent of the bleeding, and the patient's overall condition and response to the medicine. The patient should not change the dose of the medicine or discontinue treatment without consulting a doctor.
If the patient feels that the medicine is too strong or too weak, they should contact a doctor or pharmacist.
Before administration, the medicine should be warmed to room temperature or body temperature if necessary.
FEIBA NF should be prepared immediately before administration.
The prepared solution should be used immediately (the medicine does not contain preservatives).
Gently mix by rotating until the powder is completely dissolved. Ensure that FEIBA NF is completely dissolved; otherwise, fewer units of FEIBA will pass through the filter of the device.
Do not use a solution that is cloudy or contains sediment. Do not use a solution from previously opened vials.
Only use the supplied solvent (sterile water for injections) and the set for preparing the solution.
If a different set for preparing and administering the solution is used than the one supplied with FEIBA NF, ensure that a filter with a pore size of at least 149 µm is used.
Do not use if the system maintaining sterility or the medicine packaging is damaged or compromised.
Record the administration of the medicine on the attached adhesive label.
Any unused medicine or waste materials should be disposed of in accordance with local regulations.
Administration using needles:

Preparing the solution for injection

Follow aseptic procedures throughout the procedure.

• 1. Warm the closed vial containing the solvent (sterile water for injections) to room temperature if necessary, e.g., by using a water bath for a few minutes (max. 37°C).
• 2. Remove the protective caps from the vials containing the powder and solvent and disinfect the rubber stoppers of both vials.
• 3. Twist and pull to remove the sheath from one end of the supplied double-ended needle (Fig. A). Insert the exposed needle into the rubber stopper of the vial containing the solvent (Fig. B).
• 4. Remove the sheath from the other end of the double-ended needle, taking care not to touch the exposed part.
• 5. Invert the vial containing the solvent and insert the free end of the double-ended needle into the rubber stopper of the vial containing the powder (Fig. D). The solvent will be drawn into the vial containing the powder by vacuum.
• 6. Separate the two vials by withdrawing the needle from the vial containing the powder (Fig. E). Gently swirl or rotate the vial containing the powder to accelerate the dissolution process.
• 7. After the powder has dissolved, insert the needle with the air vent (Fig. F) and the foam will disappear. Remove the needle with the air vent.

Injection/infusion

Follow aseptic procedures throughout the procedure.

• 1. Remove the sheath from the supplied needle with a filter by twisting and pulling, and attach the needle to a sterile single-use syringe. Draw the solution into the syringe (Fig. G).
• 2. Detach the needle with the filter from the syringe and, after attaching the supplied infusion set with a butterfly needle (or a single-use injection needle), slowly inject the solution intravenously. A syringe pump can be used to control the infusion rate.

Information intended for healthcare professionals only:

Treatment should be initiated and supervised by a doctor experienced in the treatment of hemophilia.

Dosage

Dosage and duration of treatment depend on the severity of the clotting disorder, the location and extent of the bleeding, and the patient's clinical condition.
The dose, as well as the frequency of administration, should always be aimed at clinical efficacy in the given case.
Generally, a dose of 50-100 IU FEIBA per kg body weight is recommended; however, the single dose should not exceed 100 IU/kg body weight, and the maximum daily dose should not exceed 200 IU/kg body weight, unless the severity of the bleeding requires and justifies the use of higher doses.
Due to specific factors for the given patient, the response to the complex of clotting factors with bypassing activity may vary, and in a given case of bleeding in a patient who has an inadequate response to one of the factors, the use of another factor should be considered.
Children and adolescents
Experience with the use of FEIBA NF in children under 6 years of age is limited; the dosing regimen, the same as for adults, should be adjusted according to the child's clinical condition.

• 1)

Spontaneous bleeding

Bleeding into joints, muscles, and soft tissues

In cases of minor or moderate bleeding, a dose of 50-75 IU/kg body weight is recommended at 12-hour intervals. Treatment should be continued until clear signs of clinical improvement are observed, such as relief of pain, reduction of swelling, or mobilization of the joint.
In cases of major bleeding into muscles and soft tissues, such as bleeding into the retroperitoneal space, doses of 100 IU/kg body weight at 12-hour intervals are recommended.

Bleeding from mucous membranes

A dose of 50 IU/kg body weight is recommended every 6 hours, with close monitoring of the patient (observation of the bleeding surface, repeated hematocrit measurements in the patient). If the bleeding does not stop, the dose can be increased to 100 IU/kg body weight. The maximum daily dose should not be exceeded.

Other severe bleeding

In severe bleeding, such as bleeding into the central nervous system, a dose of 100 IU/kg body weight at 12-hour intervals is recommended. In individual cases, FEIBA NF can be administered at 6-hour intervals until clear signs of clinical improvement are observed. The maximum daily dose should not exceed 200 IU/kg body weight!

• 2)

Surgical procedures

Administer 50-100 IU/kg body weight at 6-hour intervals, taking care not to exceed the maximum daily dose.

• 3)

Prophylaxis

There are limited clinical data on the use of FEIBA NF for the prophylaxis of bleeding in patients with hemophilia.

• Prophylactic treatment of bleeding in patients with high-titer inhibitors and frequent bleeding, in whom induction of immune tolerance (ITI) has failed or is not considered: A dose of 70-100 IU/kg body weight every other day is recommended. If the bleeding does not stop, the dose can be increased to 100 IU/kg body weight administered daily, or gradually decreased.
• Prophylactic treatment of bleeding in patients with high-titer inhibitors during induction of immune tolerance (ITI): FEIBA NF can be administered concomitantly with factor VIII concentrates at doses of 50-100 IU/kg body weight twice daily, until the factor VIII inhibitor titer decreases to <2 bu.< li>

*1 Bethesda unit is defined as the amount of antibody that reduces the activity of factor VIII by 50% in fresh normal human plasma after 2 hours of incubation at 37°C.

Method of administration

See also "FEIBA NF and other medicines" and section 3 of the package leaflet.
FEIBA NF should be administered slowly intravenously (no faster than 2 IU/kg body weight per minute).
FEIBA NF should be prepared immediately before administration.
The solution should be used immediately (the medicine does not contain preservatives).
Do not use a solution that is cloudy or contains sediment. Do not use a solution from previously opened vials.
Do not use if the needle-free transfer device or double-ended needle, the system maintaining their sterility, or their packaging is damaged or compromised.
Unused solution residues should be disposed of in accordance with the applicable procedure.

Monitoring of treatment

Due to the complex mechanism of action, there is no direct method for monitoring the active substances.
The results of laboratory tests in vitro to assess the efficacy of treatment, such as aPTT, blood clotting time, and thromboelastogram (TEG), may not reflect clinical improvement. Therefore, attempts to restore normal values of these parameters by increasing the dose of FEIBA NF may be misleading and should be avoided due to the risk of DIC caused by overdose.
In case of an inadequate response to treatment with FEIBA NF, it is recommended to determine the platelet count, as a sufficient number of functionally intact platelets is necessary for the efficacy of FEIBA NF.
Do not exceed single doses of 100 IU/kg body weight and a daily dose of 200 IU/kg body weight. Patients receiving more than 100 IU/kg body weight should be monitored for the occurrence of DIC and (or) acute coronary syndrome. High doses of FEIBA NF should only be administered for the time necessary to stop the bleeding.
In case of significant changes in blood pressure, heart rate, respiratory disturbances, chest pain, and cough, the administration of the medicine should be discontinued immediately and appropriate diagnostic and therapeutic measures should be initiated.
Laboratory results indicating DIC are: decreased fibrinogen levels, decreased platelet count, and the presence of fibrin/fibrinogen degradation products (FDP).
Administration of FEIBA NF to patients with inhibitors may result in an initial anamnestic increase in inhibitor levels. Under the influence of further administration of FEIBA NF, the inhibitor level may decrease over time. Clinical and literature data indicate that the efficacy of FEIBA NF is not reduced.
During administration of FEIBA NF, patients with hemophilia complicated by the presence of inhibitors or patients with acquired inhibitors of clotting factors may experience an increased tendency to bleeding and an increased risk of thrombosis at the same time.
