1. WHAT ALPHANATE® IS AND WHAT IT IS USED FOR

Alphanate® is supplied as a powder for solution for injection containing approximately 250, 500, 1000 or 1500 IU of human coagulation factor VIII and 300, 600, 1200 or 1800 IU of human von Willebrand factor per vial (Note IU stands for international unit, a standard measure of activity).

Once reconstituted with the appropriate amount of solvent (water for injections), each vial contains approximately 50, 100 or 150 IU of FVIII/ml and 60, 120 or 180 IU VWF/ml.

Alphanate® is one of the group of medicines called clotting factors.

Alphanate® is used for the treatment and prevention of bleeding in patients with haemophilia A (congenital factor VIII deficiency).

Alphanate® is used for the treatment and prevention of bleeding (haemorrhage) or surgical bleeding in von Willebrand disease (VWD), when desmopressin (DDAVP) treatment alone is ineffective or contraindicated.

This product may be used in the management of acquired factor VIII deficiency.

2. WHAT YOU NEED TO KNOW BEFORE YOU USE ALPHANATE®

Do not use Alphanate®

•    If you are allergic to human coagulation factor VIII and von Willebrand factor complex or any of the other ingredients of this medicine (listed in section 6).

•    If you have not been fully trained how to inject yourself by your doctor or haemophilia nurse.

If you want more detailed information then ask your doctor.

Warnings and precautions

Talk to your doctor, pharmacist or nurse before using Alphanate®.

•    Rarely you may have an anaphylactic reaction (a sudden severe allergic reaction) such as rash, tightness of the chest, dizziness, vertigo or nausea, or feeling dizzy when you are standing. If these symptoms occur, you must stop using the product immediately and contact your doctor.

•    Your doctor should perform some tests to make sure that the dosage of Alphanate® you are receiving is enough to achieve and maintain appropriate factor VIII levels and thus stop any bleeding.

•    If your bleeding is not controlled with Alphanate®, consult your doctor immediately. You may have developed factor VIII inhibitors, these are antibodies which block the clotting effect of factor VIII. Your doctor will perform some tests to confirm whether the inhibitors are present in your blood.

•    During the treatment of the von Willebrand disease, there is a chance you may develop blood clots, particularly if you have known clinical risk factors. Therefore, your doctor should perform some tests to detect early signs of blood clots and recommend the treatment if necessary.

•    Patients with von Willebrand disease, especially type 3 patients, may develop antibodies (inhibitors) to von Willebrand factor. Your doctor may perform more blood tests to confirm whether the inhibitors are present in your blood.

When medicines are made from human blood or plasma, certain measures are put in place to prevent infections being passed on to patients. These include:

-    careful selection of blood and plasma donors to make sure those at risk of carrying infections are excluded,

-    the testing of each donation and pools of plasma for signs of virus/infections,

-    the inclusion of steps in the processing of the blood or plasma that can inactivate or remove viruses.

Despite these measures, when medicines prepared from human blood or plasma are administered, the possibility of passing on infection cannot be totally excluded. This also applies to any unknown or emerging viruses or other types of infections.

The measures taken are considered effective for enveloped viruses such as human immunodeficiency virus (HIV), hepatitis B virus and hepatitis C virus. The measures taken may be of limited value against non-enveloped viruses such as hepatitis A virus and parvovirus B19. Parvovirus B19 infection may be serious for pregnant women (foetal infection) and for individuals whose immune system is depressed or who have some types of anaemia (e.g. sickle cell disease or haemolytic anaemia).

Your doctor may recommend that you consider vaccination against hepatitis A and B if you regularly/repeatedly receive human plasma-derived factor VIII products.

It is strongly recommended that every time you receive a dose of Alphanate® the name and batch number of the product are recorded in order to maintain a record of the batches used.

See also section 4.

Other medicines and Alphanate®

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.

No interactions of Alphanate® with other medicines are known.

Do not mix Alphanate® with any other medicines that you receive by injection.

Pregnancy and breast-feeding

Based on the rare occurrence of haemophilia A in women, experience regarding the use of FVIII/VWF complex during pregnancy and breast-feeding is not available.

Ask your doctor or pharmacist for advice before taking any medicine.

Driving and using machines

Alphanate® has little or none effect on your ability to drive and use machines.

Sodium content

The residual content of sodium in Alphanate®, arising from the manufacturing process, does not exceed 23 mg (1 mmol) per vial. This is equivalent to 1.15% of the recommended maximum daily intake of sodium for an adult. However, depending on the body weight of the patient and the posology, the patient may receive more than one vial.

3.    HOW TO USE ALPHANATE®

Reconstitute the product as described at the end of this leaflet (please see pictograms on the back of the leaflet). The product must be given by intravenous route. The administration rate should be 3 ml/min and never more than 10 ml/min to avoid undesirable side effects. Inject Alphanate® immediately after reconstitution.

The amount of Alphanate® you should use depends on many factors, such as your weight, your clinical status and the type and severity of bleeding. Your doctor will calculate the dose, the frequency and the intervals of administration of Alphanate® in order to reach the necessary level of factor VIII or von Willebrand factor in your blood.

Your doctor will tell you the duration of your treatment with Alphanate®.

You will be given full training before using Alphanate® without the hospital supervision. Please refer to all your training materials or contact your local haemophilia centre for more information. You should not self-administer Alphanate® alone: always have a responsible adult present.

Use in children and adolescents

There are insufficient data from clinical trials to recommend the use of Alphanate® in children less than 6 years of age for the authorised indications.

If you use more Alphanate® than you should

No cases of overdose with Alphanate® have been reported. However, if you have used Alphanate® more than required, consult your doctor or pharmacist immediately.

If you forget to use Alphanate®

Proceed immediately with the following dose and continue at regular intervals as directed by your doctor. Do not take a double dose to make up for a forgotten dose.

4.    POSSIBLE SIDE EFFECTS

Like all medicines, this medicine can cause side effects, although not everybody gets them.

On rare occasions, you may have some of the following side effects after the administration of Alphanate®. Please contact your doctor immediately if you experience:

• itching, local reactions at the injection site (e.g. burning and transitory reddening)

8/9 8


•    allergic reactions (e.g. tightness of the chest/ feeling unwell, dizziness, nausea and slight drop of blood pressure than can make you feel dizzy when you are standing)

•    fever

•    faster heart beat (tachycardia)

Occasionally an anaphylactic shock may occur. If you observe any of the following symptoms during the injection/perfusion, interrupt the injection/ perfusion and contact your doctor immediately:

•    tightness of the chest/feeling unwell

•    dizziness

•    slight hypotension (slight drop of blood pressure with dizziness when you are standing)

•    nausea

Allergic reactions to the components of the product cannot be totally excluded. The formation of neutralising antibodies of factor VIII (inhibitors) is a well-known complication in the treatment of patients with haemophilia A. Study results show that first time users of factor VIII are mainly affected. You will be carefully monitored for the development of these inhibitors.

There is a chance of blood clots, particularly if you have known clinical risk factors.

Reporting of side effects If you get any side effects, talk to your doctor, pharmacist or nurse. This includes any possible side effects not listed in this leaflet. You can also report side effects directly via Yellow Card Scheme, Website: https://yellowcard.mhra.gov.uk. By reporting side effects you can help provide more information on the safety of this medicine.
