1. What Haemoctin is and what it is used for

Haemoctin is a medicine derived from human plasma, which contains coagulation factor VIII
necessary for the normal blood clotting process. After reconstitution of the powder with
water for injectable preparations, the solution is ready for intravenous injection.
Haemoctin is used for the treatment and prophylaxis of bleeding in patients with hemophilia A
(congenital factor VIII deficiency).
Haemoctin does not contain von Willebrand factor in pharmacologically active quantities and is
therefore not suitable for the treatment of von Willebrand's disease.

2. What you need to know before using Haemoctin

Do not use Haemoctin

• if you are allergic to coagulation factor VIII or any of the other ingredients of this medicine (listed in section 6). An allergic reaction may include skin rash, itching, difficulty breathing or swelling of the face, lips, throat or tongue.

Warnings and precautions
The formation of inhibitors (antibodies) is a known complication that can occur during treatment
with all factor VIII-based medicines. Inhibitors, especially at high levels, prevent the
treatment from working correctly and you or your child will be closely monitored to
check for the development of these inhibitors. If Haemoctin does not keep bleeding under control in you or
your child, inform your doctor immediately.
If you have pre-existing cardiovascular risk factors, therapy with Haemoctin may increase the risk
cardiovascular. If you have concerns, discuss them with your doctor.
Catheter-related complications: if a central venous access device (CVAD) is necessary
the risk of CVAD-related complications, including
local infections, bacteremia and thrombosis at the catheter site, must be considered.

Viral safety
When medicinal products are made from human blood or plasma, measures are taken
to prevent infections from being passed on to patients. The measures include:

• careful selection of blood and plasma donors to ensure the exclusion of possible carriers of infections.
• testing of each donation and plasma pools for viruses/infections.
• inclusion of procedures for removing and/or inactivating viruses in the manufacturing process of blood or plasma-derived products. Despite these measures, when products derived from human blood or plasma are administered, the transmission of infections cannot be completely excluded. This also applies to unknown or emerging viruses or other types of infections.

These procedures are considered effective against enveloped viruses, such as the human immunodeficiency virus (HIV), hepatitis B virus and hepatitis C virus, and the non-
enveloped hepatitis A virus.
The procedures used may be of limited effectiveness against other non-enveloped viruses
such as parvovirus B19. Parvovirus B19 infection can be severe for pregnant women
(fetal infection) and for those with a compromised immune system or certain forms of
anemia (such as sickle cell anemia or hemolytic anemia).
If you take factor VIII-derived plasma human products regularly/repeatedly
your doctor may recommend vaccination against hepatitis A and hepatitis B.
It is strongly recommended that you record the name and batch number of the product each time you receive
a dose of Haemoctin, in order to be able to always trace the batches used.

Children and adolescents
The warnings and precautions for use reported for adults must also be taken into consideration
for children and adolescents.

Other medicines and Haemoctin
Tell your doctor if you are taking, have recently taken or might take any other
medicines.
No interactions of Haemoctin with other medicines have been reported.

Pregnancy, breastfeeding and fertility
If you are pregnant, suspect you are pregnant or are planning to become pregnant, or if you are breastfeeding with
breast milk, ask your doctor for advice before taking this medicine.
Since hemophilia A is very rare in women, there are no data on the use of
factor VIII during pregnancy or breastfeeding. Studies in pregnant animals or during the
post-partum period have not been conducted.

Driving and operating machinery
Haemoctin does not impair or negligibly impairs the ability to drive vehicles or operate machinery.

Haemoctin contains sodium
Haemoctin 250 I.U. contains up to 16.1 mg (0.70 mmol) of sodium (the main component of table salt)
per vial. This corresponds to 0.81% of the recommended maximum daily intake with
the diet of an adult.
Haemoctin 500/1000 I.U. contains up to 32.2 mg (1.40 mmol) of sodium (the main component of
table salt) per vial. This corresponds to 1.61% of the recommended maximum daily
intake with the diet of an adult.

3. How to use Haemoctin

Haemoctin is intended for intravenous administration (injection into a vein). Treatment must
be carried out under the direct supervision of a physician experienced in the treatment of hemophilia A. Always use
Haemoctin exactly as your doctor has instructed. If you have any doubts, consult your doctor.

The dose and durationof treatment depend on the severity of the factor VIII deficiency, the site,
the extent of the bleeding, and the patient's clinical condition. The dose for each specific case
must be determined by the physician.
Ensure perfect sterility in all stages of the procedure.

Reconstitution of the powder:

• Bring the closed vials of solvent (water for injections) and the product to room temperature. If you use a water bath for heating, it is essential to ensure that water does not come into contact with the crimp caps or the vial stoppers, otherwise contamination of the medicinal product may occur.
• Very importantfor the correct use of the transfer system: before opening, make sure that the white lower part of the transfer system is in direct contact with the bottom of the blister (Fig. 1a: correct/ Fig. 1b: incorrect). If incorrectly positioned: push the transfer system downwards inside the blister until the white lower part of the transfer system is in direct contact with the bottom of the blister (Fig. 1c).
• Remove the crimp caps from the solvent vial and the product vial to expose the central part of the rubber stoppers (Fig. 2). Ensure that the rubber stoppers of the vials containing the product and the solvent have been treated with a disinfectant.
• Remove the upper part of the transfer system packaging (Fig. 3).
• Place the solvent vial on a flat surface. Position the blue part of the transfer system, which is located inside the blister, over the vial containing the solvent held in an upright position (Fig. 4). Do not twist the transfer system!
• Remove the remaining part of the blister from the transfer system. Do not crush the blister! The white part of the transfer system is now visible (Fig. 5).
• Place the vial containing the product on a flat surface.
• Invert the solvent vial together with the transfer system. Push the tip of the white part of the transfer system downwards to pierce the stopper of the vial containing the product (Fig. 6). The absence of air in the product vial allows the solvent to enter the product vial.
• Gently move the vial with the product to dissolve the powder. Do not shake vigorously, to avoid foaming! The solution is clear or slightly opalescent.
• Subsequently, unscrew the blue part of the transfer system together with the solvent vial by rotating counterclockwise (Fig. 7). Remove the solvent vial with the blue part of the transfer system still attached. The Luer-Lock connector is now visible.

The ready-to-use solution must be used immediately after being dissolved. Do not
use turbid solutions or those containing visible particles.

Injection:

• After dissolving the powder as described above, screw the included syringe onto the Luer-Lock connector of the vial containing the product with the white part of the transfer device (Fig. 8). This allows easy aspiration of the reconstituted drug (Haemoctin 250 I.U.: total volume 2.5 ml, Haemoctin 500 I.U./1000 I.U.: total volume 5 ml) into the syringe. It is not necessary to use a separate filter, as a filter is already present in the transfer system.
• Carefully disconnect the vial with the white part of the transfer system from the syringe. Use the butterfly needle included in the package and administer immediately by slow intravenous injection. The injection rate should not exceed 2-3 ml/minute.
• After using the butterfly needle, be sure to cover it with the protective closing cap for safety.

If you use more Haemoctin than you should
If you believe you have received an excessive amount of Haemoctin, inform your doctor, who will decide how
to proceed with treatment.

If you forget to use Haemoctin
In this case, the doctor will decide whether further treatment is necessary.

If you stop using Haemoctin
Do not stop using Haemoctin without consulting your doctor.
If you have any doubts about the use of this medicine, ask your doctor or pharmacist.

4. Possible side effects

Inform your doctor immediately if you notice any of the following effects:

• redness of the epidermis,
• burning and tingling at the infusion site,
• chills,
• flushing,
• headache,
• urticaria,
• hypotension,
• drowsiness,
• nausea,
• state of restlessness,
• tachycardia,

The following side effects have been reported with Haemoctin
Not known: frequency cannot be estimated based on available data

• Shock (anaphylactic), allergic reaction
• Redness of the skin, itching, urticaria

For children not previously treated with factor VIII-based medicines, the development of
inhibitor antibodies (see section 2) may be very common (more than 1 in 10 patients); however, in
patients who have received previous treatment with factor VIII (more than 150 days of
treatment) the risk is uncommon (less than 1 in 100 patients). If this happens, the medicine may stop
working properly for you or your child and you or your child may experience prolonged bleeding.
If this happens, you should contact your doctor immediately.

Side effects in children and adolescents
With the exception of inhibitor (antibody) development, side effects in
children are expected to be identical to those observed in adults.

The following information is intended exclusively for healthcare professionals:
Treatment Monitoring
During treatment, appropriate determination of factor VIII levels is recommended to define the dose to be administered and the frequency with which infusions should be repeated. The response to factor VIII may vary from patient to patient, with different half-lives and different recovery levels. In underweight or overweight patients, dose adjustment based on body weight may be necessary. In particular, in the case of major surgery, precise monitoring of replacement therapy by means of coagulation testing (plasma factor VIII activity) is essential.
When using a one-stage coagulation test in vitrobased on activated partial thromboplastin time (aPTT) to determine factor VIII activity in patient blood samples, the results for plasma factor VIII activity may be significantly altered by both the type of aPTT reagent and the reference standard used in the test. In addition, there may be significant discrepancies between the results obtained with a one-stage coagulation test based on aPTT and those obtained with the chromogenic test conforming to the European Pharmacopoeia. This aspect is of particular importance when the laboratory and/or the reagents used in the test change.

Dosage
The dose and duration of replacement therapy depend on the severity of the factor VIII deficiency, the site and extent of the bleeding, and the patient's clinical condition.
The number of units of factor VIII administered is expressed in International Units (IU), in relation to the current WHO standard for factor VIII-based products. The activity of factor VIII in plasma is expressed either as a percentage (relative to normal human plasma) or preferably in International Units (in reference to an International Standard for Factor VIII in plasma).
The activity of 1 International Unit (IU) of factor VIII is equivalent to the amount of factor VIII found in 1 ml of normal human plasma.

On-demand treatment
The calculation of the necessary dose of factor VIII is based on the empirical data that 1 International Unit (IU) of factor VIII per kg of body weight increases the activity of factor VIII in plasma by 1 - 2% of normal activity. The necessary dose is determined by applying the following formula:
Units required = body weight (kg) × desired increase in factor VIII (%) × 0.5
The amount to be administered and the frequency of administration must always take into account clinical efficacy in individual specific cases.
In the case of bleeding episodes reported in the table below, the activity of factor VIII must not be lower than the activity level indicated (in % of normal) in the corresponding period.
The following table can be used as a reference for dosage in the treatment of bleeding episodes and in surgical practice:

Prophylaxis
In long-term prophylaxis of bleeding in patients with severe hemophilia A, the usual dosage is 20 - 40 IU of factor VIII per kilogram of body weight at intervals of 2 – 3 days. In some cases, especially in younger patients, more frequent dosing intervals or higher doses may be necessary.

Route of administration
For intravenous use. It is recommended not to administer more than 2-3 ml per minute.
Use only the supplied infusion set, as otherwise therapy may be ineffective due to adsorption of factor VIII on the internal surfaces of some infusion devices.
Haemoctin must not be mixed with other medicinal products.
