1. What is AIMAFIX and what is it used for

AIMAFIX is a blood coagulation factor IX solution derived from human plasma. Factor IX is a protein that has an anti-haemorrhagic action.
AIMAFIX is used in the following therapies:

• in the treatment and prophylaxis (prevention) of bleeding in patients with haemophilia B (congenital factor IX deficiency).
• in the treatment of acquired factor IX deficiency.

2. What you need to know before you use AIMAFIX

Do not use AIMAFIX

• if you are allergic to factor IX or any of the other ingredients of this medicine (listed in section 6). Warnings and precautionsConsult your doctor or pharmacist before using AIMAFIX. As with any intravenous protein product, allergic-type hypersensitivity reactions are possible. AIMAFIX contains traces of human proteins other than factor IX. If you notice any of the symptoms listed below during the administration of the product, you mustimmediately stop the administration and contact your doctor, as these symptoms may be the first signs of an allergic reaction. The symptoms that may occur are:
• urticaria,
• generalised urticaria,
• a feeling of tightness in the chest,
• wheezing,
• hypotension (low blood pressure)
• anaphylaxis In case of shock, the doctor will follow the standard medical treatment for shock.

If you have cardiovascular risk factors, taking AIMAFIX may potentiate these risk factors.
If a central venous catheter (CVC) is required for the injection of AIMAFIX, the doctor must consider the risk of complications including local infections, spread of bacteria into the blood (bacteraemia) or formation of a blood clot in the blood vessel (thrombosis) where the catheter is inserted.
If you have a history of heparin-induced allergic reactions, you should avoid the use of medicines containing heparin.
After repeated treatments with human plasma coagulation factor IX, patients should be monitored for the development of neutralising antibodies (inhibitors). There are reports in the literature showing a correlation between the presence of antibodies that neutralise factor IX (inhibitors) and allergic reactions. Therefore, in patients who experience allergic reactions, the presence of an inhibitor should be considered. It should be noted that patients with factor IX inhibitors may have a higher risk of anaphylaxis (severe and rapid allergic reaction) on subsequent exposure to factor IX.
Due to the risk of allergic reactions with factor IX-based products, the first administration of factor IX should occur, in accordance with the opinion of the treating physician, under medical supervision and in an environment where appropriate medical intervention for allergic reactions can be provided.
Thromboembolism
Tell your doctor if you suffer from liver or heart disease or if you have recently undergone major surgery. Due to the potential risk of thrombotic complications, in fact, when this medicine is administered to patients with pre-existing risk factors towards liver diseases, those in the post-operative period, newborns or patients at risk of thrombotic phenomena or DIC, clinical surveillance must be undertaken, by means of appropriate biological tests, to identify the first signs of thrombotic and consumption coagulopathies.
In each of these situations, the benefit of treatment with AIMAFIX must be weighed against the risk of these complications.

Viral safety of AIMAFIX
When medicines are prepared from human blood or plasma, specific measures are put in place to prevent the transmission of infections to patients. These measures include:

• careful selection of blood and plasma donors to ensure that potentially infected donors are excluded,
• testing of each donation and plasma pool for the presence of viruses. Manufacturers of these medicines also introduce some steps into the processing of blood and plasma that are capable of inactivating or removing viruses. Despite these measures, when medicines prepared from human blood or plasma are administered, the possibility of transmission of infectious agents cannot be completely excluded. This also applies to viruses or other types of infectious agents, emerging or unknown. The measures taken are considered effective for enveloped viruses such as the human immunodeficiency virus (HIV), the hepatitis B virus (HBV), the hepatitis C virus (HCV) and the non-enveloped hepatitis A virus (HAV). The measures taken may have a limited effect against non-enveloped viruses such as parvovirus B19. Infection with parvovirus B19 can be severe in pregnancy (foetal infection) and in individuals with a compromised immune system or who have some type of anaemia (e.g. sickle cell anaemia or haemolytic anaemia). Your doctor may advise you to consider vaccination against hepatitis A and B if you regularly receive human plasma coagulation factor IX. It is strongly recommended that you record the trade name and batch number of the product each time you receive a dose of AIMAFIX, so as to maintain traceability of the batch used.

Children and adolescents
There is insufficient data to recommend the use of AIMAFIX in children under 6 years of age. The warnings and precautions listed in this section apply to both adult and paediatric populations.

Other medicines and AIMAFIX
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.
No interactions of human plasma coagulation factor IX products with other medicines are known.
AIMAFIX should not be mixed with other medicines.

Pregnancy, breastfeeding and fertility
If you are pregnant, suspect you are pregnant or are planning a pregnancy, or if you are breastfeeding, ask your doctor or pharmacist for advice before using this medicine.
Reproduction studies in animals have not been conducted with factor IX.
Due to the rare occurrence of haemophilia B in women, data on the use of factor IX during pregnancy and breastfeeding are not available. Therefore, factor IX should only be used during pregnancy and breastfeeding if clearly indicated.

Driving and using machines
AIMAFIX does not impair or negligibly impairs the ability to drive vehicles or operate machinery.

AIMAFIX contains sodium and heparin
This medicine contains up to a maximum of 41 mg of sodium (the main component of table salt) per 10 ml vial.
This is equivalent to 2.05% of the recommended daily intake with the diet of an adult.
This medicine contains heparin. Heparin can cause allergic reactions and a reduction in the number of blood cells, which can impair blood clotting. If you have had allergic reactions caused by heparin in the past, do not take medicines containing heparin.

3. How to use AIMAFIX

Use this medicine following the doctor's instructions exactly. If you have any doubts, consult your doctor
or pharmacist.
If you are administering the product on your own, always use AIMAFIX following
exactly the instructions given in the “Instructions for correct use” section.
Only the infusion devices included in the package should be used, as the treatment may
be ineffective due to the adsorption of plasma coagulation factor IX to the internal walls of
some infusion devices.
If you have any doubts, consult your doctor.
Treatment should be initiated under the supervision of a doctor experienced in the treatment of hemophilia.
Your doctor will determine the appropriate dose for you and the duration of treatment based on the severity of
factor IX deficiency, the location and extent of the bleeding, and your clinical condition.
The dose and frequency of applications should always be guided by clinical efficacy in each individual case.
During treatment, appropriate determination of factor IX levels is required to adjust the
dose to be administered and the frequency of infusions.
In particular, in the case of major surgery, it is essential to carefully monitor replacement therapy with factor IX through coagulation analysis (plasma factor IX activity).
Responses to factor IX may vary in individual patients, reaching different levels of in vivorecovery
and showing a different half-life.
The dosage calculated based on body weight may require adjustment in underweight or
overweight patients.

Further information regarding dosage and duration of therapy is included at the end of the
Bleeding prophylaxis
For long-term prophylaxis (prevention) of bleeding in patients with severe hemophilia B, the dose is normally
from 20 to 40 IU of factor IX per kg of body weight at intervals of 3 – 4 days. In some cases,
especially for younger patients, shorter therapeutic intervals or higher doses may be necessary.

Use in children and adolescents.
The safety and efficacy of AIMAFIX in children under 6 years of age have not yet been established.

Route of administration
Intravenous use.
The product must be administered intravenously, by injection or slow infusion.
It is recommended not to administer doses exceeding 100 IU/Kg of body weight per day.
The infusion rate must be evaluated for each individual patient.

Instructions for correct use
Reconstitution of the powder with the solvent:

• 1. Bring the vial of powder and solvent to room temperature;

If you use more AIMAFIX than you should
No symptoms of overdose with human plasma coagulation factor IX have been reported.
If you accidentally ingest/take an excessive dose of AIMAFIX, immediately inform your
doctor or go to the nearest hospital.
If you have any doubts about the use of AIMAFIX, consult your doctor (or pharmacist).

4. Possible side effects

Like all medicines, this medicine can cause side effects, although not everybody gets them.
Adverse reactions, known to be associated with the administration of human factor IX concentrates, may also occur with AIMAFIX.

If any of these side effects occur, contact your doctor immediately or go to the nearest hospital:

• Allergic reactions (hypersensitivity) which may manifest with a burning sensation and sharp pain at the infusion site, chills, flushing, hives (urticaria), rash all over the body (generalized urticaria), headache, low blood pressure (hypotension), restlessness, fast heartbeat (tachycardia), a feeling of tightness in the chest (chest oppression), wheezing, drowsiness (lethargy), tingling or altered sensation of the limbs or other parts of the body (paresthesia), nausea, vomiting, up to angioedema (rapid swelling of the skin and mucous membranes). In some cases, these reactions have progressed to severe anaphylaxis (including anaphylactic shock) and have occurred in close temporal association with the development of factor IX inhibitors (positive for Anti-factor IX antibodies).
• Nephrotic syndrome (a condition of severe kidney dysfunction characterized by protein loss in the urine with a consequent decrease in normal levels of these in the blood) has been reported following an attempt to induce immunological tolerance in patients with hemophilia B with factor IX inhibitors and a history of allergic reactions.
• Fever has also been observed.
• Patients with hemophilia B may develop neutralizing antibodies to factor IX (inhibitors). The presence of these inhibitors manifests with an insufficient clinical response. In such cases, it is advisable to contact a specialized hemophilia center.
• There is a potential risk of thromboembolic events (abnormal blood clot formation) following the administration of products containing factor IX, with a higher risk for poorly purified preparations. The use of factor IX products with a low degree of purity has been associated with cases of myocardial infarction, disseminated intravascular coagulation (widespread coagulation in blood vessels), venous thrombosis (blood clots in the veins) and pulmonary embolism (blood clots in the lungs). The use of highly purified factor IX is rarely associated with the occurrence of such adverse reactions.

Additional side effects in children and adolescents
No specific data are available for the pediatric population.

The following information is intended exclusively for doctors or healthcare professionals.
See also section 3.
Dosage:
The dosage and duration of replacement therapy depend on the severity of the factor IX deficiency, the
site and extent of the haemorrhage, and the patient's clinical condition.
The number of units of factor IX administered is expressed in International Units (IU), correlated to the current
WHO standard for factor IX-based products. The activity of factor IX in plasma is expressed either as a
percentage (relative to normal human plasma) or in International Units (relative to an international
standard for plasma factor IX).
The activity of one International Unit (IU) of factor IX is equivalent to the amount of factor IX
contained in one millilitre of normal human plasma.
Treatment on demand
The calculation of the factor IX dose required is based on the empirical observation that 1 International Unit
(IU) of factor IX per Kg of body weight increases plasma factor IX activity by 0.8% of normal activity. The
necessary dose is calculated using the following formula:

Units required = body weight (Kg) x desired increase in factor IX (%) (IU/dl) x (reciprocal of
observed recovery)
The amount to be administered and the frequency of applications must always be guided by clinical
effectiveness in each individual case.
In the case of the following haemorrhagic events, the activity of factor IX during the corresponding period must not fall
below the given level of plasma activity (as % of normal). The following table can be used
as a reference in haemorrhagic and surgical episodes:

Grade of haemorrhage/Type ofFactor IX levelFrequency of doses (hours)/
surgical procedurerequired (%) (IU/dl)Duration of therapy (days)
Haemorrhage
Early haemarthrosis, muscle haemorrhage or oral 20 – 40 Repeat every 24 hours. At least 1
haemorrhage day, until the haemorrhagic episode
indicated by pain is resolved or healing
has occurred.
Haemarthrosis, muscle haemorrhage 30 – 60 Repeat infusion every 24 hours for
or more extensive haematomas 3 – 4 days or more, until pain and
severe disability have passed.
Life-threatening haemorrhages 60 – 100 Repeat infusion every 8 - 24 hours
until symptoms resolve.
Surgery
Minor surgery, 30 – 60 Every 24 hours, at least 1 day, until
including tooth extractions healing.
Major surgery 80 – 100 Repeat infusion every 8 - 24 hours
(pre- and post-operative) until adequate wound healing; then therapy for at least
another 7 days to maintain
a factor IX activity of 30% to
60% (IU/dl).

Prophylaxis
For long-term prophylaxis of haemorrhages in patients with severe haemophilia B, the usual doses are 20 to
40 IU of factor IX per kg of body weight at intervals of 3 – 4 days.
In some cases, especially in younger patients, shorter therapeutic intervals or higher doses may be necessary.
Paediatric population
The safety and efficacy of AIMAFIX in children under the age of 6 years have not yet been established.
Monitoring of treatment
During treatment, appropriate determination of factor IX levels is required to adjust the
dose to be administered and the frequency of infusions. Responses to factor IX may vary in individual
patients, achieving different levels of in vivorecovery and showing a different half-life. The dose
calculated based on body weight may require adjustment and monitoring of factor IX levels
in underweight or overweight patients. In particular, in the case of major surgery, it is essential
to carefully monitor replacement therapy through coagulation analysis (plasma factor IX activity).
When using an in vitro“one-stage” coagulation test based on activated partial thromboplastin time (aPTT) for
determining factor IX activity in patient blood samples, the results of plasma factor IX activity may be significantly affected by both the type of aPTT reagent and
the reference standard used in the test. This is particularly important when changing the
laboratory and/or reagents used in the test.

Special warnings and precautions for use
Inhibitors
After repeated treatments with human plasma coagulation factor IX-based products, patients
should be monitored for the development of neutralising antibodies (inhibitors) which must be quantified
in Bethesda Units (BU) using appropriate biological assays.
There are reports in the literature showing a correlation between the presence of factor IX inhibitors and
allergic reactions. Therefore, in patients who experience allergic reactions, the presence of an inhibitor should be evaluated. It should be noted that patients with factor IX inhibitors may have a higher risk of
anaphylaxis upon subsequent exposure to factor IX.
Due to the risk of allergic reactions with factor IX-based products, the initial administration of
factor IX should occur, in accordance with the attending physician's opinion, under medical supervision and in an
environment where appropriate medical care for allergic reactions can be provided.
