FEIBA NF, 500 units (50 units/ml), powder and solvent for solution for injection
Anti-inhibitor Coagulant Complex
FEIBA NF is a medicine obtained from human plasma, which enables blood clotting in cases of deficiency or absence 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 non-hemophilic patients with 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 complete and permanent elimination of 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 factor von Willebrand inhibitor.
Inform your doctor if you have any allergies.
Inform your doctor if you are on a low-sodium diet.
In the following situations, FEIBA NF should not be used if alternative treatment is possible:
See 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 an infusion-related reaction/hypersensitivity reaction occur (see section 4), administration of this medicine should be discontinued and appropriate medical care should be initiated.
In patients with suspected hypersensitivity to the medicine or any of its components, the doctor will decide on re-administration of 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.
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 high-titer inhibitors and life-threatening bleeding or risk of bleeding (e.g., post-traumatic or post-operative):
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 at risk of transmitting infections are excluded, as well as testing of individual blood samples 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.
Measures 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. Measures may have limited value against non-enveloped viruses, such as parvovirus B19. Parvovirus B19 infection can be serious in pregnant women (fetal infection) and in individuals with impaired immune function 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 hepatitis B surface antigen 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 a patient, the name and batch number of the medicine should be clearly recorded to maintain information on the batches used.
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 coagulation 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 venous access with isotonic sodium chloride solution before and after administration of FEIBA NF.
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".
No effects on the ability to drive and use machines have been observed.
The medicine contains 40 mg of sodium (the main component of common salt) per vial. This corresponds to 2% of the maximum recommended daily intake of sodium in the diet for adults.
The lyophilized powder FEIBA NF is dissolved in the supplied solvent and administered intravenously.
This medicine should always be used exactly as prescribed by your doctor. If you are unsure, consult your doctor or pharmacist.
Treatment should be initiated and supervised by a doctor experienced in the treatment of coagulation disorders.
The doctor will determine the appropriate dose and frequency of administration individually for each patient, taking into account the severity of the coagulation disorder, the location and extent of bleeding, and the patient's overall condition and response to the medicine. Do not change the dose of the medicine yourself or stop treatment without consulting your doctor.
If you feel that the medicine is too strong or too weak, contact your 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).

Treatment should be initiated and supervised by a doctor experienced in the treatment of hemophilia.
Dosage and duration of treatment depend on the severity of the coagulation disorder, the location and extent of bleeding, and the patient's clinical condition.
Dose, as well as frequency of administration, should always be aimed at clinical efficacy in the given case.
Generally, a dose of 50-100 units of FEIBA per kg body weight is recommended; however, the single dose should not exceed 100 units/kg body weight, and the maximum daily dose should not exceed 200 units/kg body weight, unless the severity of bleeding requires and justifies the use of higher doses.
Due to specific factors for the given patient, the response to the anti-inhibitor coagulant complex may vary, and in a given case of bleeding in a patient in whom the response to one of the factors is insufficient, 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 schedule, the same as for adults, should be adjusted according to the child's clinical condition.
In cases of minor or moderate bleeding, a dose of 50-75 units/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 units/kg body weight at 12-hour intervals are recommended.
A dose of 50 units/kg body weight every 6 hours is recommended, with close monitoring of the patient (observation of the bleeding surface, repeated hematocrit measurements in the patient). If bleeding does not stop, the dose can be increased to 100 units/kg body weight. Do not exceed the maximum daily dose of 200 units/kg body weight.
In severe bleeding, such as bleeding into the central nervous system, a dose of 100 units/kg body weight at 12-hour intervals is recommended. In individual cases, FEIBA NF can be administered at 6-hour intervals until clear clinical improvement is observed. Do not exceed the maximum daily dose of 200 units/kg body weight!
Administer 50-100 units/kg body weight at 6-hour intervals, taking care not to exceed the maximum daily dose.
There are limited clinical data on the use of FEIBA NF for prophylaxis of bleeding in patients with hemophilia.
*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.
See also section "FEIBA NF and other medicines" and section 3 of the package leaflet.
FEIBA NF should be administered slowly intravenously (no faster than 2 units/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 if the needleless transfer device or double-ended needle, the system maintaining their sterility, or their packaging is damaged or compromised.
Unused solution should be disposed of in accordance with the applicable procedure.
Due to the complex mechanism of action, there is no direct method for monitoring the active substances.
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 cases of insufficient 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 units/kg body weight and a daily dose of 200 units/kg body weight. Patients receiving more than 100 units/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 period necessary to stop bleeding.
In cases of significant changes in blood pressure, heart rate, respiratory disturbances, chest pain, and cough, administration of the medicine should be discontinued immediately and appropriate diagnostic and therapeutic measures should be initiated.
Laboratory results indicating DIC include 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, in patients with hemophilia complicated by the presence of inhibitors or in patients with acquired inhibitors of clotting factors, there may be a simultaneous tendency to bleeding and an increased risk of thrombosis.
