1. What is IMMUNINE and what is it used for

IMMUNINE is a concentrate of coagulation factor IX. It replaces the factor IX that is missing or not working properly in hemophilia B. Hemophilia B is a hereditary and sex-linked bleeding disorder caused by a deficiency of factor IX. It causes severe bleeding into joints, muscles, and internal organs, either spontaneously or as a result of accidental or surgical trauma. Administration of IMMUNINE temporarily corrects the factor IX deficiency and reduces the tendency to bleed.

IMMUNINE is used for the treatment and prophylaxis of bleeding episodes in patients with congenital hemophilia B.

IMMUNINE is indicated for all age groups, from children over 6 years to adults.

There are not enough data to recommend the use of IMMUNINE in children under 6 years of age.

2. What you need to know before you use IMMUNINE

Do not use IMMUNINE

• If you are allergicto human coagulation factor IX or to any of the other components of this medicine (listed in section 6).

• If you have a known allergy to heparin or have had an abnormal decrease in the number of blood cells involved in the formation of blood clots caused by heparin administration (heparin-induced thrombocytopenia).

After adequate treatment of these situations, IMMUNINE should only be used in case of life-threatening bleeding episodes.

Warnings and precautions

Consult your doctor or pharmacist before starting treatment with IMMUNINE.

When allergic reactions occur:

There is a rare possibility that you may experience a sudden and severe allergic reaction (anaphylactic reaction) to IMMUNINE.

If you detect one or more of the following symptoms, stop administration immediately and seek medical assistance at once. They may be signs of anaphylactic shock and require immediate urgent treatment.

• redness of the skin
• rash
• hives
• itching all over the body
• swelling of lips and tongue
• difficulty breathing
• difficulty inhaling or exhaling due to constriction of the airways
• chest tightness
• general discomfort
• dizziness
• decrease in blood pressure
• loss of consciousness

When monitoring is required:

• It is possible that your doctor may want to perform some tests to ensure that the dose you receive is sufficient to achieve and maintain adequate factor IX levels in the blood.
• Your doctor will monitor you closely to detect possible complications:
• • if you receive high doses of IMMUNINE
  • if you are prone to developing thrombosis. In this case, you will receive lower levels of factor IX, the active ingredient of IMMUNINE.

When bleeding continues:

• If your bleeding does not come under control with IMMUNINE, consult your doctor immediately. It is possible that you have developed factor IX inhibitors. Factor IX inhibitors are antibodies present in the blood that counteract the effect of factor IX. This reduces the effectiveness of IMMUNINE in treating bleeding episodes. Your doctor will perform the necessary tests to confirm this.

• There may be a connection between the development of factor IX inhibitors and allergic reactions. Patients with factor IX inhibitors may have a higher risk of severe allergic reactions (anaphylaxis). Therefore, in patients who suffer an allergic reaction, the presence of a factor IX inhibitor should be investigated.

Tell your doctor if you have heart or liver disease or if you have recently undergone major surgery, as there is a higher risk of blood clotting complications.

Safety information regarding infectious agent transmission

When human plasma or blood-derived medicines are administered, certain measures must be taken to prevent infections from being transmitted to patients. These measures include:

• careful selection of donors to exclude those who are at risk of being carriers of infectious diseases
• testing for specific infection markers in individual donations and plasma pools to detect possible viruses or infections
• inclusion of stages in the manufacturing process to eliminate/inactivate viruses.

Despite this, when human blood or plasma-derived medicines are administered, the possibility of transmitting infectious agents cannot be completely excluded. This also applies to emerging or unknown viruses or other types of infections.

These measures are considered effective for enveloped viruses such as human immunodeficiency virus (HIV), hepatitis B virus, and hepatitis C virus, and for the non-enveloped hepatitis A virus.

The measures taken may have limited value against other non-enveloped viruses such as parvovirus B19 (the virus that causes erythema infectiosum).

Parvovirus B19 infection can be severe for a pregnant woman (fetal infection) and for individuals whose immune system is depressed or for patients with certain types of anemia (e.g., sickle cell anemia or hemolytic anemia).

Your doctor may recommend that you be vaccinated against hepatitis A and hepatitis B if you are regularly or repeatedly administered human plasma-derived medicines.

It is strongly recommended that, each time a dose of IMMUNINE is administered, a record be kept of the name of the medicine and the batch number administered in order to maintain a record of the batches used.

Children

There are not enough data to recommend the use of IMMUNINE in children under 6 years of age.

Using IMMUNINE with other medicinesTell your doctor or pharmacist if you are taking or have recently taken or might take any other medicines.

No interactions of IMMUNINE with other medicines are known.

Pregnancy and breastfeeding

Hemophilia B is rare in women. Therefore, there is currently no experience with the use of IMMUNINE during pregnancy and breastfeeding.

If you are pregnant or breastfeeding, think you may be pregnant or are planning to have a baby, ask your doctor for advice before taking this medicine.

Your doctor will decide whether you can use Immunine during pregnancy and breastfeeding.

Driving and using machines

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

IMMUNINE contains sodium chloride and sodium citrate

This medicine contains 41 mg of sodium (the main component of cooking/table salt) in each vial. This is equivalent to 2% of the maximum recommended daily intake of sodium for an adult.

3. How to use IMMUNINE

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

Your doctor will decide what dose is appropriate for you. He will calculate the dose according to your individual needs. Tell your doctor if you think the effect of Immunine is too strong or too weak.

Use in children

There are not enough data to recommend the use of IMMUNINE in children under 6 years of age.

Monitoring by your doctor

Your doctor will perform the appropriate laboratory tests at regular intervals to ensure that you have sufficient factor IX levels. This is especially important if you are going to undergo major surgery or life-threatening bleeding.

Patients with inhibitors

If the factor IX level in the blood does not reach the expected levels, or if bleeding is not controlled after an adequate dose, the presence of factor IX inhibitors should be suspected. Your doctor will check for the presence of inhibitors by performing the appropriate tests. In case of inhibitor development, contact a specialized hemophilia center.

If you have developed factor IX inhibitors, you may need a higher dose of IMMUNINE to control bleeding. If this dose does not control your bleeding, your doctor may consider using an alternative medicine. Do not increase the total dose of IMMUNINE you use to control your bleeding without consulting your doctor.

Frequency of administration

Your doctor will tell you how often and at what intervals IMMUNINE should be administered. He will calculate it for your individual case, depending on your response to IMMUNINE.

Route and/or method of administration

IMMUNINE is administered slowlyinto a vein (intravenously) after preparing the solution with the provided solvent.

Before administration, IMMUNINE should not be mixed with other medicines. This may affect the efficacy and safety of the product.

Please follow your doctor's instructions strictly.

The rate of administration will depend on the discomfort you may feel, without exceeding 2 ml per minute.

• Use only the administration equipment provided. If other administration equipment is used, incorrect dosing may occur as a result of IMMUNINE adsorption to the inner surfaces of some infusion equipment.
• If you are also receiving other products through the same venous access, you mustflush the access with a suitable solution, such as physiological saline, before and afteradministration of IMMUNINE.
• IMMUNINE must be reconstituted only immediately before administration, and the solution must be used immediately. (The solution does not contain preservatives). The infusion must be completed within 3 hours of reconstitution.
• The injectable solution is clear or slightly milky (opalescent). Do not use cloudy solutions or those containing visible particles.
• Any unused solution must be disposed of properly.

Reconstitution of the powder to prepare an injectable solution:

Prepare the solution in the cleanest and most sterile conditions possible!

1. Warm the closed vial with the rubber stopper containing the solvent (sterilized water for injectable preparations) to room temperature (max. 37°C).
2. Remove the protectors from the vials with rubber stoppers containing the powder and solvent (fig. A) and clean the rubber stoppers of both vials.
3. Remove the seal covering one end of the transfer needle by twisting and pulling it. Insert the needle through the rubber stopper of the solvent vial (fig. B and C).
4. Remove the seal covering the other end of the transfer needle, taking care not to touch the exposed end.
5. Invert the solvent vial over the powder vial and insert the free end of the transfer needle into the powder vial, piercing the stopper (fig. D). The vacuum in the powder vial will aspirate the solvent.
6. After all the solvent has passed into the powder vial, separate the two vials by removing the transfer needle from the powder vial (fig. E). Gently swirl the powder vial to accelerate dissolution.
7. Once the powder is completely dissolved, insert the provided venting needle (Fig. F) and any foam that may have formed will disappear. Remove the venting needle.

Injection/Infusion:

Prepare the solution in the cleanest and most sterile conditions possible!

1. Remove the protector from the provided filter needle by twisting and pulling it, and attach it to a sterile disposable syringe. Aspirate the solution with the syringe (fig. G).
2. Separate the syringe from the filter needle and inject the solution slowly (maximum rate of 2 ml per minute) intravenously with the provided infusion equipment (or with the included disposable needle).

If the product is administered by infusion, use the disposable winged infusion set with an appropriate filter.

This information is intended for healthcare professionals only:

Posology and method of administration

Treatment should be initiated under the supervision of a doctor experienced in the treatment of haemophilia.

Posology

The dose and duration of replacement therapy depend on the severity of the factor IX deficiency, the location and extent of the bleeding, and the patient's clinical condition.

The number of units of factor IX administered is expressed in International Units (IU), which are related to the current WHO standard for factor IX 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 of factor IX concentrates in plasma).

One International Unit (IU) of factor IX activity is equivalent to the amount of factor IX present in one ml of normal human plasma.

On-demand treatment

The calculation of the required dose of factor IX is based on the empirical finding that 1 International Unit (IU) of factor IX per kg of body weight increases the activity of factor IX in plasma by 1.1% of normal activity in patients 12 years and older.

The required dose is determined using the following formula:

Required IU = body weight (kg) x desired increase in factor IX (%)(IU/dl) x 0.9

The amount to be administered and the frequency of administration should always be guided by the individual clinical efficacy. Factor IX products are rarely needed to be administered more than once a day.

In the case of the following bleeding episodes, the activity of factor IX should not fall below the given plasma activity level (in % of normal or in IU/dl) during the corresponding time period.

In surgery and bleeding episodes, the following table can be used as a dosing guide:

Prophylaxis

For long-term prophylaxis against bleeding 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 to 4 days.

In some cases, especially in younger patients, shorter dosing intervals or higher doses may be required.

During the course of treatment, it is recommended to determine the factor IX levels appropriately as a guide to the dose to be administered and the frequency of repeated infusions. In particular, in the case of major surgical interventions, exact monitoring of replacement therapy by means of coagulation analysis (plasma factor IX activity) is essential. The response to factor IX may vary in each individual patient, achieving different recovery levels in vivo and showing different half-lives.

Paediatric population

According to available clinical data, the recommended posology in the paediatric population can be performed in patients from 12 to 18 years of age. There are insufficient clinical data to provide a recommended posology in patients between 6 and 12 years of age.

Adverse reactions

Special populations

The use of IMMUNINE was investigated in paediatric patients with haemophilia B. The safety profile was similar to that of adults using IMMUNINE.

The use of IMMUNINE was investigated in two observational studies in children up to 6 years of age and in patients from 0 to 64 years of age with haemophilia B, respectively. The safety profile in children up to 6 years of age was similar to that of children over 6 years of age and to that of adults using IMMUNINE.
