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.
Special Warnings and
Special Precautions
for Use
Risk
of
Thrombotic
and
Thromboembolic Events
Thrombotic and thromboembolic events,
including
disseminated
intravascular
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
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
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

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
fibrinogen values, decreased platelet count
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
FEIBA NF. However, inhibitor formation is

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.
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.

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

is still the subject of scientific debate.
However, recent scientific work indicates a
role of specific components of the activated

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

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
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.
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

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.

Reporting of suspected adverse reactions
Reporting suspected adverse reactions after authorisation of FEIBA NF is important. It allows continued
monitoring of the benefit/risk balance of FEIBA NF. Healthcare professionals are asked to report any
suspected adverse reactions to the Ministry of Health according to the National Regulation by using an
online form
(http://forms.gov.il/globaldata/getsequence/getsequence.aspx?formType=AdversEffectMedic@moh.health

4.9 OVERDOSAGE
Some of the reported thromboembolic events occurred with doses above 200 U/kg. If signs or symptoms
of thromboembolic events are observed, the infusion should be stopped immediately and appropriate
diagnostic and therapeutic measures initiated. See Section 4.4
5. PHARMACOLOGICAL PROPERTIES
5.1 Pharmacodynamic properties
Pharmacotherapeutic group: blood coagulation factors, ATC 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 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.

Powder:
Sodium chloride
Sodium citrate
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.
