1. What is Optivate and what is it used for

Optivate is a highly purified concentrate of factor VIII obtained from human plasma from tested donors. It is a white or pale yellow sterile powder, supplied with water for injections. Optivate is administered by intravenous injection for the prevention and treatment of bleeding in patients with hemophilia A (congenital factor VIII deficiency in the blood). The doctor may explain in more detail why this medicine has been prescribed.

2. Important information before using Optivate

When not to use Optivate:

• if the patient is allergic (hypersensitive) to human factor VIII or any of the other ingredients of this medicine (listed in section 6).

Warnings and precautions

• In case of more abundant or longer bleeding than usual, and if the bleeding does not stop after injection of Optivate, the patient should consult a doctor. In some patients with factor VIII deficiency, during treatment, inhibitors (antibodies) against factor VIII may develop. As a result, the treatment may not work as it should. The treating doctor will regularly order tests to detect any antibodies, especially before surgery. Both before and after the end of treatment with this medicine, especially during the first treatment cycle, the doctor will likely order tests to check the level of factor VIII in the blood.
• This medicine may contain small amounts of antibodies against blood group antigens originally present in the donors' plasma. This is normal, and in most cases, these antibodies do not cause any problems. However, if it is necessary to administer large doses of Optivate, for example during surgery, and the patient has blood group A, B, or AB, the doctor may order a blood test to check if the medicine affects red blood cells.

Complications related to catheterization: if it is necessary to use a device that provides access to the central vein (CVAD, central venous access device), the risk of complications associated with the use of CVAD should be considered, including local infections, bacteremia, and thrombosis at the catheter insertion site. For medicines produced from human blood or plasma, certain measures are taken to prevent the transmission of infections to patients. These measures include:

• careful selection of blood and plasma donors to ensure the exclusion of donors who may be carriers of infections,
• testing of individual blood samples and plasma pools for the presence of viruses/infections,
• use of blood and plasma processing stages that can inactivate or remove viruses.

Despite these measures, during the administration of medicines prepared from human blood or plasma, it is not possible to completely exclude the possibility of transmitting an infection. This also applies to unknown or newly discovered viruses and other types of infections. The measures taken are considered effective against enveloped viruses, such as human immunodeficiency virus (HIV), hepatitis B virus, and hepatitis C virus, as well as non-enveloped hepatitis A virus. The effectiveness of these measures may be limited for non-enveloped viruses, such as parvovirus B19. Parvovirus B19 infection can be dangerous for pregnant women (fetal infection) and for people with weakened immune systems or with certain types of anemia (e.g., sickle cell or hemolytic). It is recommended that before each administration of a dose of Optivate to the patient, the name and batch number of the product be recorded for the purpose of recording the batches used. Patients who regularly or repeatedly receive products with factor VIII from human plasma may be advised by their doctor to consider vaccination against viral hepatitis A and B.

Optivate and other medicines

Optivate should not be mixed in the same syringe with other medicines. The patient should tell their doctor about all medicines they are currently taking or have recently taken, as well as any medicines they plan to take.

Pregnancy, breastfeeding, and fertility

If the patient is pregnant or breastfeeding, thinks they may be pregnant, or plans to have a child, they should consult their doctor before using this medicine.

Driving and using machines

The effect of this medicine on the ability to drive and use machines is not known.

3. How to use Optivate

Before injecting the medicine at home, patients will be trained at a hemophilia treatment center in the administration of the medicine. Only the recommended injection equipment supplied with the medicine should be used. This medicine should always be used exactly as prescribed by the doctor. In case of doubts, the patient should consult their doctor. The doctor will explain what dose to use and when to take the medicine. The doctor usually prescribes a dose in relation to the number of whole vials for the most suitable dose. If further treatment is needed, subsequent doses can be administered every 8, 12, or 24 hours, depending on the needs. The doctor will provide the patient with information if necessary. The following table shows the approximate doses of factor VIII needed to stop bleeding in different conditions:

Adults:

What dose is needed to prevent bleeding in adults?

Usually, a dose of 20 to 40 IU/kg every 2 or 3 days is sufficient.

Children

In children under 6 years of age, the doctor will recommend the appropriate dose, but it usually ranges from 17 to 30 IU/kg. It can be administered up to 3 times a week to prevent bleeding.

Patients who have not been treated before

The safety and efficacy of Optivate have not been established in patients who have not been treated before.

When to inject Optivate

• The medicine should be injected after the first symptoms of bleeding appear.
• Injections should be repeated as needed until the bleeding stops.
• Each bleeding episode should be evaluated individually in terms of severity.
• In case of first-time use of the product, the doctor should supervise the patient.

Dissolving the medicine before use

The medicine should be dissolved onlyin the sterile water for injections supplied with the product.

• 1. Optivate should be dissolved only in the water for injections supplied with the product.
• 2. Before removing the cap, check that the Optivate vial and the supplied water vial are at room temperature (between 20°C and 30°C).
• 3. The water for injections intended for use with Optivate is supplied in a glass vial with a rubber stopper.
• 4. Optivate is supplied with the appropriate amount of water for injections, as presented in the table.

How to dissolve Optivate

The medicine can be dissolved using a transfer system called Mix2Vial:

The Mix2Vial transfer system is supplied with the medicine to enable easy, safe use without the need for a needle. Preparation of the solution is as follows:

	Step 1 Remove the cap from the vial and wipe the top of the rubber stopper with an alcohol swab. Repeat this step for the vial of water for injections. Remove the top part of the Mix2Vial transfer system packaging, but leave it in the packaging.
	Step 2 Place the blue end of the Mix2Vial transfer system on the water vial and press down until the needle pierces the rubber stopper, until it clicks. Remove the outer plastic packaging from the Mix2Vial transfer system and discard it, being careful not to touch the exposed end of the Mix2Vial transfer system.
	Step 3 Turn the water vial upside down without removing the Mix2Vial transfer system from it. Place the transparent end of the Mix2Vial transfer system on the Optivate vial and press down until the needle pierces the rubber stopper, until it clicks.
	Step 4 The water for injections will automatically flow into the Optivate vial due to the vacuum in the vial. Gently turn the vial to mix the product thoroughly. Do not shake the vial. Usually, within 2 to 2.5 minutes (maximum 5 minutes), a clear or slightly pearl-like solution is obtained.
	Step 5 Separate the empty water vial and the blue part from the transparent part by twisting them in the opposite direction of the clock hands. Draw air into the empty syringe by pulling the plunger to the required volume of added water. Attach the syringe to the transparent part of the Mix2Vial transfer system. Inject air from the syringe into the vial.
	Step 6 Immediately turn the vial with the solution upside down and draw the solution into the syringe. Disconnect the filled syringe from the Mix2Vial transfer system. The product is now ready for administration. The patient should follow the usual safety procedures when administering the medicine. The product should be

Note:If more than one vial of the product is needed to administer a dose, the patient should repeat steps 1 to 6 by drawing the solution from the vial into the same syringe. The Mix2Vial transfer system supplied with the product is sterile and intended for single use. After completing the dissolution process, it should be discarded into a container for contaminated items. The patient should not use this medicine if:

• the water does notflow into the vial with the medicine (this means that the vacuum in the vial has been lost; in this case, the medicine must notbe used)
• if during step 6, there are any particles in the syringe, if the solution is cloudy, or if a gelor clotforms (in this case, the patient should inform Bio Products Laboratory, providing the batch number printed on the vial).

Using a higher dose of Optivate than recommended

In case of suspected overdose, the patient should stop injecting the medicine and consult a doctor. If the patient knows they have taken too much of the medicine, they should contact their doctor as soon as possible.

Missing a dose of Optivate

The patient should not take a double dose to make up for a missed dose. They should inject the normal dose as soon as possible and then continue dosing as recommended by their doctor or a specialized nurse in hemophilia treatment.
