contraindications

Posology, dosage &

administration

Surgery

50-100 U/kg bw should be given at

intervals of up to 6 hours, a maximum

daily dose of 200 U/kg bw should not

be exceeded.

Surgery

In surgical interventions, an initial dose of 100 U/kg body

weight may be administered preoperatively, and a further

dose of 50 – 100 U/kg body weight may be administered after

6 – 12 hours. As a postoperative maintenance dose, 50 – 100

U/kg body weight may be administered at 6 – 12-hour

intervals; dosage, dosage intervals and duration of the peri-

and postoperative therapy are guided by the surgical

intervention, the patient’s general condition and the clinical

efficacy in each individual case. (The maximum daily dose of

200 U/kg body weight must not be exceeded!)

Surgery

50-100 U/kg bw should be given at intervals of up to 6

hours, a maximum daily dose of 200 U/kg bw should not

be exceeded.

Use of FEIBA NF in special patient groups

See Section 5.1 for information in relation to hemophilia B

patients with factor IX inhibitor.

In combination with factor VIII concentrate, NF was also

used for long term therapy to achieve complete and

permanent elimination of the factor VIII inhibitor.

coagulation

(DIC),

venous

thrombosis,

pulmonary

embolism,

myocardial

infarction, and stroke, have occurred in the

Hypersensitivity Reactions

FEIBA NF can precipitate allergic-type hypersensitivity

reactions

that

have

included,

urticaria,

angioedema,

gastrointestinal

manifestations,

bronchospasm,

hypotension; these reactions can be severe and can be

systemic (e.g., anaphylaxis with urticaria and angioedema,

The risk of thrombotic and thromboembolic

events may be increased with high doses of

FEIBA NF. Some of these events occurred

with doses above 200 U/kg/day or in

patients

with

other

risk

factors

thromboembolic

events.

possible

presence of such risk factors should always

be considered in patients with congenital

and acquired hemophilia.

A single dose of 100 U/kg body weight and

a daily dose of 200 U/kg body weight

should not be exceeded unless the severity

of bleeding warrants and justifies the use of

higher doses. Patients receiving more than

100 U/kg body weight must be monitored

for the development of DIC and/or acute

coronary ischemia. When used to stop

bleeding, the product should be given only

for as long as absolutely necessary to

achieve the therapeutic goal.

In the following situations FEIBA NF

should only be used when no reaction to

treatment

with

other

appropriate

coagulation factor concentrates is to be

expected- such as in case of a high inhibitor

titre and a life-threatening haemorrhage or

risk of bleeding e.g. posttraumatic or

postoperative.

Disseminated

Intravascular

Coagulation (DIC):

Liver damage

Due to the delayed clearance of

activated

coagulation

factors,

patients

with

impaired

liver

function are at increased risk of

developing DIC.

Coronary

heart

disease,

acute

thrombosis and/or embolism.

Allergic-Type Hypersensitivity Reactions

As with any intravenously administered

plasma

products,

allergic

type

hypersensitivity

reactions

occur.

Patients should be informed of the early

signs of hypersensitivity reactions including

hives, generalised urticaria, tightness of the

chest, wheezing, drop in blood pressure and

anaphylactic shock. If these symptoms

occur,

patients

should

At the first sign or symptom of an infusion/hypersensitivity

reaction, FEIBA NF administration should be stopped and

medical care initiated as appropriate.

When considering re-exposure to FEIBA NF in patients with

suspected hypersensitivity to the product or any of its

components, the expected benefit and the risk of re-exposure

must be carefully weighed, taking into account the known or

suspected type of the patient’s hypersensitivity (allergic or

non-allergic),

including

potential

Thromboembolic Events

Thromboembolic

events,

including

disseminated

intravascular

coagulation

(DIC),

venous

thrombosis,

pulmonary embolism, myocardial infarction, and stroke, have

occurred in the course of treatment with FEIBA NF. Some of

these events occurred with doses above 200 U/kg/day or in

patients with other risk factors (including DIC, advanced

atherosclerotic disease, crush injury or septicemia) for

thromboembolic

events.

Concomitant

treatment

with

recombinant Factor Vlla may increase the risk of developing

a thromboembolic event.

The possible presence of such risk factors should always be

considered

patients

with

congenital

acquired

hemophilia.

FEIBA NF should be used with particular caution and only if

there are no therapeutic alternatives in patients with an

increased risk of thromboembolic complications.

These

include, but are not limited to, patients with a history of

coronary heart disease, liver disease, DIC, arterial or venous

thrombosis, post-operative immobilization, elderly patients

and neonates.

If signs or symptoms of thrombotic and thromboembolic

events are observed, the infusion should be stopped

immediately and appropriate diagnostic and therapeutic

measures initiated.

A single dose of 100 U/kg body weight and a daily dose of

200 U/kg body weight should not be exceeded unless the

severity of bleeding warrants and justifies the use of higher

doses. When used to stop bleeding, the product should be

given only for as long as absolutely necessary to achieve the

therapeutic goal.

Therapy monitoring

Individual doses of 100 U/kg body weight and daily doses of

200 U/kg body weight must not be exceeded.

Patients

receiving more than 100 U/kg body weight must be

monitored for the development of DIC and/or acute coronary

ischemia.. High doses of FEIBA NF should be administered

only as long as strictly necessary – in order to stop a

hemorrhage.

If clinically significant changes in blood pressure or pulse

rate, respiratory distress, coughing or chest pain occur, the

infusion is to be discontinued immediately and appropriate

diagnostic and therapeutic measures are to be initiated.

Significant laboratory parameters for DIC are a drop in

fibrinogen, a drop of the thrombocyte count and/or the

preventative

therapy

alternative

therapeutic agents.

In patients with a history of hypersensitivity

reactions

prophylactic

administration

antihistamines may be indicated.

Appropriate

vaccination

should

be

considered in patients with an inhibitor

As

the

quantity

of

in

the

maximum daily dose may exceed 200 mg,

special

care

should

be

taken

with

individuals on a low sodium diet.

Monitoring of Therapy

Individual doses of 100 U/kg body weight

and daily doses of 200 U/kg body weight

must not be exceeded. Patients who receive

an individual dose of 100 U/kg body weight

are to be monitored carefully, particularly

with regard to the development of a DIC or

the occurrence of symptoms of acute

coronary ischaemia. High doses of FEIBA

NFshould be administered only as long as

strictly necessary to stop a haemorrhage.

If clinically significant changes in blood

pressure or pulse rate, respiratory distress,

coughing or chest pain occur, the infusion is

discontinued

immediately

appropriate

diagnostic

measures are to be initiated. Laboratory

parameters indicative at DIC are decreased

and/or the presence of fibrin/fibrinogen

degradation products (FDP).

Other

parameters

include

prolonged

thrombin

time,

prothrombin time, or aPTT.

If coagulation parameters are suspicious of

DIC, a physician experienced in coagulation

therapies should be consulted.

There is insufficient data in children under 6

years of age to recommend the use of

therapy. Case studies have shown the

successful use of FEIBA NF in the young

age group.

FEIBA NF 500 U and FEIBA NF 1000 U

contain approx. 80 mg sodium (calculated)

per vial. This has to be attended for patients

on low sodium diet.

Acquired haemophilia

Patients with inhibitor haemophilia or with

acquired inhibitors to coagulation factors,

who are treated with FEIBA NF, may have

increased bleeding tendency as well as

increased risk of thrombosis at the same

time.

presence of fibrin/fibrinogen degradation products (FDP).

Other parameters for DIC are a clearly prolonged thrombin

time, prothrombin time or aPTT. In patients with inhibitor

hemophilia or with acquired inhibitors to factors VIII, IX

and/or XI, the aPTT is prolonged by the underlying disease.

Patients with inhibitor hemophilia or with acquired inhibitors

to coagulation factors, who are treated with FEIBA NF, may

have increased bleeding tendency as well as increased risk of

thrombosis at the same time.

Laboratory tests and clinical efficacy

In vitro tests, such as aPTT, whole blood coagulation time

(WBCT) and thromboelastograms (TEG) as proof of efficacy

do not have to correlate with the clinical picture. Therefore,

attempts to normalize these values by increasing the dose of

FEIBA NF cannot be successful, and are even to be strongly

rejected because of the possible risk of triggering a DIC

through overdosing.

Significance of the thrombocyte count

If the response to treatment with FEIBA NF is inadequate,

conducting a thrombocyte count is recommended since a

sufficient number of functionally intact thrombocytes is

necessary for the efficacy of FEIBA NF.

PRECAUTIONS

Thromboembolic Complications

In the following situations, FEIBA NF is to be applied only if

no reaction to treatment with suitable blood coagulation

factor concentrates can be expected – e.g. in case of a high

inhibitor titer and a life-threatening hemorrhage or risk of

bleeding (e.g. post-traumatically or postoperatively):

Disseminated intravascular coagulation

(DIC): laboratory findings and/or clinical

symptoms

Liver

damage:

delayed

clearance of activated coagulation factors,

patients with impaired liver function are at

increased risk of developing DIC.

Coronary heart disease, acute thrombosis

and/or embolism.

Patients who receive FEIBA NF should be monitored for the

development of DIC, acute coronary ischemia, and signs and

symptoms of other thromboembolic events. At the first signs

or symptoms of thrombotic and thromboembolic events, the

infusion should be stopped immediately and appropriate

diagnostic and therapeutic measures initiated.

Discordant Response to Bypassing Agents

Due to patient-specific factors the response to a bypassing

agent can vary, and in a given bleeding situation patients

experiencing insufficient response to one agent may respond

to another agent. In case of insufficient response to one

bypassing agent, use of another agent should be considered.

Anamnestic Responses

Administration of FEIBA NF to patients with inhibitors may

result in an initial “anamnestic” rise in inhibitor levels. Upon

continued administration of FEIBA NF, inhibitors may

decrease over time. Clinical and published data suggest that

the efficacy of FEIBA NF is not reduced.

Hepatitis B Surface Antibodies and Test Interpretation

After administration of high doses of FEIBA NF, the

transitory rise of passively transferred Hepatitis B surface

antibodies may result in misleading interpretation of positive

Laboratory Tests and Clinical Efficacy

In vitro tests, such as aPTT, whole blood

clotting

time

(WBCT)

thromboelastograms (TEG) as proof of

efficacy do not have to correlate with the

clinical picture. Therefore, attempts to

normalise these values by increasing the

dose of FEIBA NF cannot be successful,

and are even to be strongly rejected because

of the possible risk of triggering a DIC

through overdosing.

Significance of Platelet Count

In case of inadequate response to treatment

with FEIBA NF it is recommended to

perform a platelet count, since a sufficient

number of functionally intact platelets are

considered necessary for the efficacy of

FEIBA NF.

Measures to prevent transmission of

infectious agents

Standard measures to prevent infections

resulting from the use of medicinal products

prepared from human blood or plasma

include selection of donors, screening of

individual donations and plasma pools for

specific

makers

infection

inclusion of effective manufacturing steps

for the inactivation/removal of viruses.

Despite this, when medicinal products

prepared from human blood or plasma are

administered, the possibility of transmitting

infective agents cannot be totally excluded.

This also applies to unknown or emerging

viruses or other pathogens.

The measures taken are considered effective

for enveloped viruses such as human

immunodeficiency virus (HIV), hepatitis B

virus (HBV) and hepatitis C virus (HCV),

and for the non-enveloped virus hepatitis A

virus (HAV) and Parvovirus B19.

Appropriate vaccination (against hepatitis A

and B) should be considered for patients in

regular/repeated receipt of plasma-derived

products including FEIBA NF.

In the interest of patients, it is strongly

recommended that name and batch number

of the product be recorded every time

FEIBA is administered in order to be able to

link patient and product batch.

Other Precautions

Discordant Response to Bypassing Agents

Due to patient-specific factors the response

to a bypassing agent can vary, and in a

given bleeding situation patients

experiencing insufficient response to one

agent may respond to another agent. In case

of insufficient response to one bypassing

agent, use of another agent should be

considered.

Anamnestic Responses

Administration of FEIBA to patients with

inhibitors may result in an initial

results in serological testing.

Pediatrics

Case reports and limited clinical trial data suggest that FEIBA

NF can be used in children younger than 6 years of age. The

same dose regimen as in adults should be adapted to the

child’s clinical condition.

Prophylactic use in hemophilia B patients with inhibitors

Due to the rarity of the disease, only limited clinical data is

available for the prophylaxis of bleeding in hemophilia B

patients (literature case reports, n = 4, and clinical data in

prophylaxis study 090701, n = 1).

Transmission of infectious agents

Standard measures to prevent infections resulting from the

use of medicinal products prepared from human blood or

plasma include selection of donors, screening of individual

donations and plasma pools for specific markers of infection

and the inclusion of effective manufacturing steps for the

inactivation / removal of viruses. Despite this, when

medicinal products prepared from human blood or plasma are

administered, the possibility of transmitting infective agents

cannot be totally excluded. This also applies to unknown or

emerging viruses and other pathogens.

The measures taken are considered effective for enveloped

viruses such as HIV, HBV and HCV, and for the non-

enveloped virus HAV. The measures taken may be of limited

value against non-enveloped viruses such as parvovirus B19.

Parvovirus B19 infection may be serious for pregnant women

(fetal infection) and for individuals with immunodeficiency

or increased erythropoiesis (e.g. haemolytic anaemia).

It is strongly recommended that every time that FEIBA NF is

administered to the 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.

Appropriate vaccination (hepatitis A and B) should be

considered for patients in regular/ repeated receipt of human

plasma-derived products including FEIBA NF.

Excipient related considerations

FEIBA NF contains approximately 4 mg sodium (calculated)

per ml; it is approx. 80 mg sodium for the presentation 500 U

and 1000 U FEIBA NF.

This is to be taken into

consideration in patients on a low sodium diet.

preventative therapy or alternative therapeutic agents.

In patients with a history of hypersensitivity reactions to

plasma

derivatives

prophylactic

administration

antihistamines may be indicated.

Appropriate vaccination should be considered in patients

with an inhibitor against a coagulation factor.

As the quantity of sodium in the maximum daily dose may

exceed 200 mg, special care should be taken with

individuals on a low sodium diet.

Monitoring of Therapy

There is insufficient data in children under 6 years of age to

recommend the use of FEIBA NF. However, inhibitor

formation is a common occurrence in haemophilic children

undergoing factor VIII replacement therapy. Case studies

have shown the successful use of FEIBA NF in the young age

group.

FEIBA NF 500 U and FEIBA NF 1000 U contain approx. 80

mg sodium (calculated) per vial. This has to be attended for

patients on low sodium diet.

with

acquired

inhibitors to coagulation factors, who are treated with FEIBA

NF, may have increased bleeding tendency as well as

aminocaproic acid in combination with

FEIBA NF.

If treatment with both antifibrinolytics such

as epsilon-aminocaproic acid and FEIBA

NF is indicated, the two products should be

administered at least 6 hours apart.

No adequate and well-controlled studies of the combined or

sequential use of FEIBA NF and recombinant Factor VIIa or

antifibrinolytics have been conducted.

The possibility of

thromboembolic events should be considered when systemic

antifibrinolytics such as tranexamic acid and aminocaproic

acid are used during treatment with FEIBA NF. Therefore,

antifibrinolytics should not be used for approximately 6 to

12 hours after the administration of FEIBA NF.

In cases of concomitant rFVIIa use a

potential drug

interaction cannot be excluded according to available in vitro

data and clinical observations (potentially resulting in adverse

events such as thromboembolic event).

It is not recommended to use antifibrinolytics such as epsilon-

both in vitro and in vivo, its active principle

is still the subject of scientific debate.

However, recent scientific work indicates a

role of specific components of the activated

code: B02BD03.

Although FEIBA NF was developed in the early seventies

and its factor VIII inhibitor bypassing activity has been

proven in vitro as well as in vivo, its mode of action is still

the subject of scientific discussion. FEIBA NF, as found with

activity assays, is composed of prothrombin complex

zymogens which are both procoagulant (prothrombin FVII,

FIX, FX) and anticoagulant (protein C) in relatively equal

quantities to the arbitrary FEIBA NF potency unit but its

procoagulant enzyme content is relatively low. FEIBA NF,

thus, contains the proenzymes of the prothrombin complex

factors, but only very small amounts of their activation

products, with the contents of FVIIa being the highest.

[Turecek PL and Schwarz HP. Chapter 4: Factor Eight

Inhibitor Bypassing Activity, in Production of Plasma

Proteins for Therapeutic Use, eds. Joseph Bertolini, Neil

Goss, John Curling, Wiley 2013, ISBN: 978-0-470-92431-0].

Current scientific works point to the role of specific

components

activated

prothrombin

complex,

prothrombin (F II) and activated factor X (FXa) in the mode

of action of FEIBA NF. [Turecek PL, Varadi K, Gritsch H,

et al. Factor Xa and Prothrombin: Mechanism of Action of

FEIBA NF. Vox Sang. 77: 72-79, 1999]

FEIBA NF controls bleeding by induction and facilitation of

thrombin generation, a process for which the formation of the

prothrombinase-complex is crucial. A number of biochemical

in vitro and in vivo studies have shown that FXa and

prothrombin play a critical role in the activity of FEIBA NF.

The prothrombinase complex has been found to be a major

target site for FEIBA NF. Apart from prothrombin and FXa,

FEIBA NF contains other proteins of the prothrombin

complex,

Treatment of hemophilia B patients with inhibitors

The experience in hemophilia B patients with factor IX

inhibitors is limited due to the rarity of the disease. Five

hemophilia B patients with inhibitors were treated with

FEIBA

during

clinical

trials

either

on-demand,

prophylactically or for surgical interventions:

In a prospective open-label, randomized, parallel clinical study

in hemophilia A or B patients with persistent high-titer

inhibitors (090701, PROOF), 36 patients were randomized to

either 12 months ± 14 days of prophylactic or on-demand

therapy. The 17 patients in the prophylaxis arm received 85 ±

15 U/kg FEIBA NF administered every other day and the 19

patients in the on-demand arm were treated individually

determined by the physician. Two hemophilia B patients with

inhibitors were treated in the on-demand arm and one

hemophilia B patient was treated in the prophylactic arm.

The median ABR (annualized bleeding rate) for all types of

bleeding episodes in patients in the prophylaxis arm (median

ABR = 7.9) was less than that of patients in the on-demand

arm (median ABR = 28.7), which amounts to a 72.5%

reduction in median ABRs between treatment arms.

another

completed

prospective

non-interventional

surveillance study of the perioperative use of FEIBA NF

(PASS-INT-003, SURF) a total of 34 surgical procedures

were performed in 23 patients. The majority of patients (18)

were congenital hemophilia A patients with inhibitors, two

were hemophilia B patients with inhibitors and three were

patients with acquired hemophilia A with inhibitors. The

duration of FEIBA NF exposure ranged from 1 to 28 days,

with a mean of 9 days and a median of 8 days. The mean

cumulative dose was 88,347 U and the median dose was

59,000 U. For hemophilia B patients with inhibitors, the

longest exposure to FEIBA NF was 21 days and the maximum

dose applied was 7324 U.

In addition 36 case reports are available when FEIBA NF was

used for treatment and prevention of bleeding episodes in

hemophilia B patients with factor IX inhibitor (24 hemophilia

B patients with inhibitors were treated on-demand, four

hemophilia

were

treated

prophylactically and eight hemophilia B patients with

inhibitors were treated for surgical procedures).

There are also isolated reports on the use of FEIBA NF in the

treatment of patients with acquired inhibitors to factors X, XI

and XIII.

As the mode of action of FEIBA NF is still being discussed,

it is not possible to make a conclusive statement about the

pharmacokinetic properties.

4.2. Posology and Method of Administration

The treatment should be initiated and supervised by a physician experienced in the management of

coagulation disorders.

Posology

Dosage and duration of the therapy depend on the severity of the haemostasis disorders, the localization

and the extent of the bleeding, as well as the clinical condition of the patient.

Dosage and frequency of administration should always be guided by the clinical efficacy in the individual

case.

As a general guideline a dose of 50 to 100 U of FEIBA NF per kg body weight (bw) is recommended; a

single dose of 100 U/kg body weight and a maximum daily dose of 200 U/kg body weight must not be

exceeded unless the severity of bleeding warrants and justifies the use of higher doses. See Section 4.4.

Paediatric use (children)

The experience in children under 6 years of age is limited; the same dose regimen as in adults should be

adapted to the child’s clinical condition.

1) Spontaneous Bleeding

Joint, Muscle and Soft Tissue Haemorrhage

A dose of 50-75 U/kg body weight at 12-hour intervals is recommended for minor to moderately severe

bleeding The treatment should be continued until a clear improvement of the clinical symptoms, e.g.

reduction relief of pain, decrease of swelling or increase of joint mobility occurs.

For severe muscle and soft tissue bleeding, e.g. retroperitoneal hemorrhages, a dose of 100 U/kg body

weight at 12-hour intervals is recommended.

Mucous Membrane Haemorrhage

A dose of 50 U/kg body weight every 6 hours under careful monitoring of the patient (visual control of

bleeding, repeated determination of hematocrit) is recommended. If the bleeding does not stop, the dose

may be increased to 100 U/kg body weight, however a daily dose of 200 U/kg body weight must not be

exceeded.

Other Severe Haemorrhages

In severe hemorrhage, such as CNS bleeding, a dose of 100 U/kg body weight at 12-hour intervals is

recommended. In individual cases, FEIBA NF may be administered at 6-hour intervals, until clear

improvement of the clinical condition is achieved. (The maximum daily dose of 200 U/kg body weight must

not be exceeded!)

2) Surgery

In surgical interventions, an initial dose of 100 U/kg body weight may be administered preoperatively, and

a further dose of 50 – 100 U/kg body weight may be administered after 6 – 12 hours. As a postoperative

maintenance dose, 50 – 100 U/kg body weight may be administered at 6 – 12-hour intervals; dosage,

3) Use of FEIBA NF in special patient groups

See Section 5.1 for information in relation to hemophilia B patients with factor IX inhibitor.

In combination with factor VIII concentrate, FEIBA NF was also used for long term therapy to achieve

complete and permanent elimination of the factor VIII inhibitor.

Monitoring

In case of inadequate response to treatment with the product, it is recommended that a platelet count be

performed because a sufficient number of functionally intact platelets is considered to be necessary for

the efficacy of the product.

FEIBA NF 500U, 1000U with BAXJECT II Hi-Flow Device_ SPC_

License holder update_090120

Due to the complex mechanism of action, no direct monitoring of active ingredients is available.

Coagulation tests such as the whole blood coagulation time (WBCT), the thromboelastogram (TEG, r-

value) and the aPTT usually show only little reduction and do not necessarily correlate with the clinical

efficacy. Therefore these tests have little significance in the monitoring of the therapy with FEIBA NF. See

Section 4.4.

Method of Administration

Reconstitute the product as described in Section 6.6 RECONSTITUTION OF THE POWDER FOR

SOLUTION FOR INJECTION WITH THE BAXJECT II HI-FLOW OR RECONSTITUTION OF THE

POWDER FOR SOLUTION FOR INJECTION WITH TRANSFER NEEDLE, and inject or infuse slowly by

the intravenous route only. Do not exceed an injection/infusion rate of 2 U/kg bw per minute.

4.3 CONTRAINDICATIONS

FEIBA NF must not be used in the following situations if therapeutic alternatives to FEIBA NF are

available:

Hypersensitivity to the product or any of the components.

Disseminated Intravascular Coagulation (DIC).

Acute thrombosis or embolism (including myocardial infarction).

See Section 4.4.

4.4 SPECIAL WARNINGS AND SPECIAL PRECAUTIONS FOR USE

WARNINGS

Hypersensitivity Reactions

FEIBA

precipitate

allergic-type

hypersensitivity

reactions

that

have

included,

urticaria,

angioedema, gastrointestinal manifestations, bronchospasm, and hypotension; these reactions can be

severe and can be systemic (e.g., anaphylaxis with urticaria and angioedema, bronchospasm, and

circulatory shock). Other infusion reactions, such as chills, pyrexia, and hypertension have also been

reported.

Patients should be informed of the early signs of hypersensitivity reactions, for example erythema, skin

rash,

generalized

urticaria,

pruritus,

breathing

difficulties/dyspnoea,

tightness

chest,

general

indisposition, dizziness and drop in blood pressure up to allergic shock.

At the first sign or symptom of an infusion/hypersensitivity reaction, FEIBA NF administration should be

stopped and medical care initiated as appropriate.

When considering re-exposure to FEIBA NF in patients with suspected hypersensitivity to the product or

any of its components, the expected benefit and the risk of re-exposure must be carefully weighed, taking

into account the known or suspected type of the patient’s hypersensitivity (allergic or non-allergic),

including potential remedial and/or preventative therapy or alternative therapeutic agents.

Thromboembolic Events

Thromboembolic events, including disseminated intravascular coagulation (DIC), venous thrombosis,

pulmonary embolism, myocardial infarction, and stroke, have occurred in the course of treatment with

FEIBA NF. Some of these events occurred with doses above 200 U/kg/day or in patients with other risk

factors (including DIC, advanced atherosclerotic disease, crush injury or septicemia) for thromboembolic

events. Concomitant treatment with recombinant Factor Vlla may increase the risk of developing a

thromboembolic event.

The possible presence of such risk factors should always be considered in patients with congenital and

acquired hemophilia.

FEIBA NF should be used with particular caution and only if there are no therapeutic alternatives in

patients with an increased risk of thromboembolic complications. These include, but are not limited to,

patients with a history of coronary heart disease, liver disease, DIC, arterial or venous thrombosis, post-

operative immobilization, elderly patients and neonates.

If signs or symptoms of thrombotic and thromboembolic events are observed, the infusion should be

stopped immediately and appropriate diagnostic and therapeutic measures initiated.

A single dose of 100 U/kg body weight and a daily dose of 200 U/kg body weight should not be exceeded

unless the severity of bleeding warrants and justifies the use of higher doses. When used to stop

FEIBA NF 500U, 1000U with BAXJECT II Hi-Flow Device_ SPC_

License holder update_090120

bleeding, the product should be given only for as long as absolutely necessary to achieve the therapeutic

goal.

Therapy monitoring

Individual doses of 100 U/kg body weight and daily doses of 200 U/kg body weight must not be exceeded.

Patients receiving more than 100 U/kg body weight must be monitored for the development of DIC and/or

acute coronary ischemia.. High doses of FEIBA NF should be administered only as long as strictly

necessary – in order to stop a hemorrhage.

If clinically significant changes in blood pressure or pulse rate, respiratory distress, coughing or chest pain

occur,

infusion

discontinued

immediately

appropriate

diagnostic

therapeutic

measures are to be initiated. Significant laboratory parameters for DIC are a drop in fibrinogen, a drop of

thrombocyte

count

and/or the presence of fibrin/fibrinogen degradation products (FDP). Other

parameters for DIC are a clearly prolonged thrombin time, prothrombin time or aPTT. In patients with

inhibitor hemophilia or with acquired inhibitors to factors VIII, IX and/or XI, the aPTT is prolonged by the

underlying disease.

Patients with inhibitor hemophilia or with acquired inhibitors to coagulation factors, who are treated with

FEIBA NF, may have increased bleeding tendency as well as increased risk of thrombosis at the same

time.

Laboratory tests and clinical efficacy

In vitro tests, such as aPTT, whole blood coagulation time (WBCT) and thromboelastograms (TEG) as

proof of efficacy do not have to correlate with the clinical picture. Therefore, attempts to normalize these

values by increasing the dose of FEIBA NF cannot be successful, and are even to be strongly rejected

because of the possible risk of triggering a DIC through overdosing.

PRECAUTIONS

Thromboembolic Complications

In the following situations, FEIBA NF is to be applied only if no reaction to treatment with suitable blood

coagulation factor concentrates can be expected – e.g. in case of a high inhibitor titer and a life-

threatening hemorrhage or risk of bleeding (e.g. post-traumatically or postoperatively):

Disseminated intravascular coagulation (DIC): laboratory findings and/or clinical symptoms

Liver damage: Due to the delayed clearance of activated coagulation factors, patients with

impaired liver function are at increased risk of developing DIC.

Coronary heart disease, acute thrombosis and/or embolism.

Patients who receive FEIBA NF should be monitored for the development of DIC, acute coronary

ischemia, and signs and symptoms of other thromboembolic events. At the first signs or symptoms of

thrombotic and thromboembolic events, the infusion should be stopped immediately and appropriate

diagnostic and therapeutic measures initiated.

Discordant Response to Bypassing Agents

Due to patient-specific factors the response to a bypassing agent can vary, and in a given bleeding

situation patients experiencing insufficient response to one agent may respond to another agent. In case

of insufficient response to one bypassing agent, use of another agent should be considered.

Anamnestic Responses

Administration of FEIBA NF to patients with inhibitors may result in an initial “anamnestic” rise in inhibitor

levels. Upon continued administration of FEIBA NF, inhibitors may decrease over time. Clinical and

published data suggest that the efficacy of FEIBA NF is not reduced.

Hepatitis B Surface Antibodies and Test Interpretation

After administration of high doses of FEIBA NF, the transitory rise of passively transferred Hepatitis B

surface antibodies may result in misleading interpretation of positive results in serological testing.

FEIBA NF 500U, 1000U with BAXJECT II Hi-Flow Device_ SPC_

License holder update_090120

Pediatrics

Case reports and limited clinical trial data suggest that FEIBA NF can be used in children younger than 6

years of age. The same dose regimen as in adults should be adapted to the child’s clinical condition.

Prophylactic use in hemophilia B patients with inhibitors

Due to the rarity of the disease, only limited clinical data is available for the prophylaxis of bleeding in

hemophilia B patients (literature case reports, n = 4, and clinical data in prophylaxis study 090701, n = 1).

Transmission of infectious agents

Standard measures to prevent infections resulting from the use of medicinal products prepared from

human blood or plasma include selection of donors, screening of individual donations and plasma pools

for specific markers of infection and the inclusion of effective manufacturing steps for the inactivation /

removal of viruses. Despite this, when medicinal products prepared from human blood or plasma are

administered, the possibility of transmitting infective agents cannot be totally excluded. This also applies to

unknown or emerging viruses and other pathogens.

The measures taken are considered effective for enveloped viruses such as HIV, HBV and HCV, and for

the non-enveloped virus HAV. The measures taken may be of limited value against non-enveloped

viruses such as parvovirus B19. Parvovirus B19 infection may be serious for pregnant women (fetal

infection)

individuals

with

immunodeficiency

increased

erythropoiesis

(e.g.

haemolytic

anaemia).

It is strongly recommended that every time that FEIBA NF is administered to the 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.

Appropriate vaccination (hepatitis A and B) should be considered for patients in regular/ repeated receipt

of human plasma-derived products including FEIBA NF.

Excipient related considerations

FEIBA NF contains approximately 4 mg sodium (calculated) per ml; it is approx. 80 mg sodium for the

presentation 500 U and 1000 U FEIBA NF. This is to be taken into consideration in patients on a low

sodium diet.

4.5 Interactions with other medicinal products and other forms of interaction

No adequate and well-controlled studies of the combined or sequential use of FEIBA NF and recombinant

Factor VIIa or antifibrinolytics have been conducted. The possibility of thromboembolic events should be

considered when systemic antifibrinolytics such as tranexamic acid and aminocaproic acid are used

during treatment with FEIBA NF. Therefore, antifibrinolytics should not be used for approximately 6 to

12 hours after the administration of FEIBA NF.

In cases of concomitant rFVIIa use a potential drug interaction cannot be excluded according to available

in vitro data and clinical observations (potentially resulting in adverse events such as thromboembolic

event).

4.6 Fertility, pregnancy and lactation

There are no adequate data from the use of FEIBA NF in pregnant or lactating women. Physicians should

balance the potential risks and only prescribe FEIBA NF if clearly needed, taking into consideration that

pregnancy and the postpartum period confer an increased risk of thromboembolic events, and several

complications of pregnancy that are associated with an increased risk of DIC.

No animal reproduction studies have been conducted with FEIBA NF, and the effects of FEIBA NF on

fertility have not been established in controlled clinical trials.

4.7 Effects on the ability to drive and use machines

FEIBA NF has no, or negligible, influence on the ability to drive or to use machines.

4.8 Undesirable effects

The adverse reactions presented in this section have been reported from post marketing surveillance as

well as from 2 studies with FEIBA NF for the treatment of bleeding episodes in pediatric and adult patients

with hemophilia A or B and inhibitors to factors VIII or IX. One study also enrolled acquired hemophilia

patients with factor VIII inhibitors (2 of 49 patients). The adverse reactions from a third study comparing

prophylaxis with on-demand treatment have been added.

been proven in vitro as well as in vivo, its mode of action is still the subject of scientific discussion. FEIBA

NF, as found with activity assays, is composed of prothrombin complex zymogens which are both

procoagulant (prothrombin FVII, FIX, FX) and anticoagulant (protein C) in relatively equal quantities to the

arbitrary FEIBA NF potency unit but its procoagulant enzyme content is relatively low. FEIBA NF, thus,

contains the proenzymes of the prothrombin complex factors, but only very small amounts of their

activation products, with the contents of FVIIa being the highest. [Turecek PL and Schwarz HP. Chapter 4:

Factor Eight Inhibitor Bypassing Activity, in Production of Plasma Proteins for Therapeutic Use, eds.

Joseph Bertolini, Neil Goss, John Curling, Wiley 2013, ISBN: 978-0-470-92431-0].

Current scientific works point to the role of specific components of the activated prothrombin complex,

prothrombin (F II) and activated factor X (FXa) in the mode of action of FEIBA NF. [Turecek PL, Varadi K,

Gritsch H, et al. Factor Xa and Prothrombin: Mechanism of Action of FEIBA NF. Vox Sang. 77: 72-79,

1999]

FEIBA NF controls bleeding by induction and facilitation of thrombin generation, a process for which the

formation of the prothrombinase-complex is crucial. A number of biochemical in vitro and in vivo studies

have shown that FXa and prothrombin play a critical role in the activity of FEIBA NF. The prothrombinase

complex has been found to be a major target site for FEIBA NF. Apart from prothrombin and FXa, FEIBA

NF contains other proteins of the prothrombin complex, which could also facilitate haemostasis in

haemophilia patients with inhibitors.

Treatment of hemophilia B patients with inhibitors

The experience in hemophilia B patients with factor IX inhibitors is limited due to the rarity of the disease.

Five hemophilia B patients with inhibitors were treated with FEIBA NF during clinical trials either on-

demand, prophylactically or for surgical interventions:

In a prospective open-label, randomized, parallel clinical study in hemophilia A or B patients with

persistent high-titer inhibitors (090701, PROOF), 36 patients were randomized to either 12 months ± 14

days of prophylactic or on-demand therapy. The 17 patients in the prophylaxis arm received 85 ± 15 U/kg

FEIBA NF administered every other day and the 19 patients in the on-demand arm were treated

individually determined by the physician. Two hemophilia B patients with inhibitors were treated in the on-

demand arm and one hemophilia B patient was treated in the prophylactic arm.

The median ABR (annualized bleeding rate) for all types of bleeding episodes in patients in the

prophylaxis arm (median ABR = 7.9) was less than that of patients in the on-demand arm (median ABR =

28.7), which amounts to a 72.5% reduction in median ABRs between treatment arms.

In another completed prospective non-interventional surveillance study of the perioperative use of FEIBA

NF (PASS-INT-003, SURF) a total of 34 surgical procedures were performed in 23 patients. The majority

of patients (18) were congenital hemophilia A patients with inhibitors, two were hemophilia B patients with

inhibitors and three were patients with acquired hemophilia A with inhibitors. The duration of FEIBA NF

exposure ranged from 1 to 28 days, with a mean of 9 days and a median of 8 days. The mean cumulative

dose was 88,347 U and the median dose was 59,000 U. For hemophilia B patients with inhibitors, the

longest exposure to FEIBA NF was 21 days and the maximum dose applied was 7324 U.

In addition 36 case reports are available when FEIBA NF was used for treatment and prevention of

bleeding episodes in hemophilia B patients with factor IX inhibitor (24 hemophilia B patients with inhibitors

were treated on-demand, four hemophilia B patients with inhibitors were treated prophylactically and eight

hemophilia B patients with inhibitors were treated for surgical procedures).

There are also isolated reports on the use of FEIBA NF in the treatment of patients with acquired inhibitors

to factors X, XI and XIII.

5.2 Pharmacokinetic properties

As the mode of action of FEIBA NF is still being discussed, it is not possible to make a conclusive

statement about the pharmacokinetic properties.

5.3 Preclinical Safety data

Based on acute toxicity studies with factor VIII knockout mice and normal mice and rats with higher doses

than the maximum daily dose for humans (> 200 U/kg of body weight), it can be concluded that the side

effects in connection with FEIBA NF mainly result from hypercoagulation due to the pharmacological

properties.

Solvent:

Sterilized Water for Injections

6.2 Incompatibilities

This medicinal product must not be mixed with other medicinal products except the solvent mentioned in

Section 6.6.

As in all blood coagulation preparations, the efficacy and tolerance of the medicinal product may be

impaired by being mixed with other medicinal products. It is advisable to rinse a common venous access

with a suitable solution, e.g. with isotonic saline solution, before and after the administration of FEIBA NF.

Coagulation factors derived from human plasma may be adsorbed by the inner surfaces of certain types

of injection/infusion devices. If this were to occur, it could result in failure of therapy. Therefore, only

approved plastic infusion devices may be used with FEIBA NF.

6.6. Special precautions for disposal and other handling advice

To prepare the FEIBA NF solution, use only the sterilised water for injections and the reconstitution device

provided in the pack. Use aseptic technique throughout entire procedure. FEIBA NF is to be reconstituted

only immediately before administration. The solution should then be used straight away (the solution does

not contain preservatives). Swirl gently until all material is dissolved. Ensure that FEIBA NF is completely

dissolved; otherwise, less FEIBA NF Units will pass through the device filter. After reconstitution, the

solution should be inspected for particulate matter and discoloration prior to administration.
