ADVATE – Oktokog alfa uses, dose and side effects

}

250 IU, 500 IU, 1000 IU, 1500 IU powder and solvent for solution for injection. 
Octocog alfa ( recombinant human coagulation factor VIII)

1. What ADVATE is and what it is used for

ADVATE contains the active substance octocog alfa, human coagulation factor VIII produced by recombinant DNA technology. Factor VIII is needed for the blood to form clots and stop bleeding. In patients with hemophilia A (congenital factor VIIIdeficiency ), this is absent or does not function normally.

ADVATE is used to treat and prevent bleeding in patients of all ages who have hemophilia A (a hereditary form of hemophilia caused by a factor VIII deficiency ).

ADVATE is manufactured without the addition of any human or animal protein throughout the manufacturing process.

2. What you need to know before using ADVATE

Do not use ADVATE

  • If you are allergic to octocog alfa or any of the other ingredients of this medicine (listed in section 6).
  • If you are allergic to mouse or hamster protein.

If you are not sure, ask your doctor.

Warnings and cautions

Talk to your doctor before using ADVATE. Tell your doctor if you have previously been treated with factor VIII products, especially if you have developed inhibitors, as there may be a greater risk of recurrence. Inhibitors are blocking antibodies to factor VIII, which reduce the effect of ADVATE in preventing or controlling bleeding. The development of inhibitors is a known complication in the treatment of hemophilia. Contact your doctor immediately if your bleeding is not controlled with ADVATE.

There is a small risk of you getting an anaphylactic reaction (a severe, sudden allergic reaction ) from ADVATE. You should be aware of early signs of allergic reactions such as rash, hives, general itching, swelling of the lips and tongue, difficulty breathing, pressure over the chest, general malaise, and dizziness. These symptoms can be an early symptom of anaphylactic shock, reactions that may also include severe dizziness, unconsciousness, and severe difficulty breathing.

If you experience any of these symptoms, stop the injection/infusion immediately, and contact your doctor. Severe symptoms, such as difficulty breathing and fainting, require immediate emergency treatment.

Patients developing factor VIII inhibitors

The development of inhibitors ( antibodies ) is a known complication that may occur during treatment with any factor VIII drug. The inhibitors prevent, especially at high levels, that the treatment works properly. You or your child will be closely monitored for the development of such inhibitors. If you or your child suffer from bleeding that cannot be controlled with ADVATE, tell your doctor immediately.

Children and young people

The information on warnings and precautions applies to both adults and children (from 0 to 18 years).

Other medicines and ADVATE

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

Pregnancy and breastfeeding

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor for advice before using this medicine.

Driving and using machines

ADVATE has no effect on the ability to drive and use machines.

ADVATE contains sodium

This medicine contains 0.45 mmol sodium (10 mg) per vial. This should be considered by patients on a low-salt diet.

Incorrect administration of ADVATE

Improper administration ( injection into an artery or outside the vein) should be avoided, as mild, short-term reactions at the injection site, such as bruising and erythema, may occur.

3. How to use ADVATE

Treatment with ADVATE will be initiated by a physician experienced in the management of patients with hemophilia A.

Your doctor will calculate the dose of an ADVATE (in international units or IU) depending on your condition, your weight, and whether it is used to prevent or treat bleeding. How often the treatment is given depends on how well ADVATE works on you. Replacement treatment with ADVATE is usually a lifelong treatment.

Always use this medicine exactly as your doctor has told you. Consult a doctor if you are unsure.

Prevention of bleeding

The usual dose is 20 – 40 IU octocog alfa per kg body weight given every two to three days. In some cases, especially in young patients, more frequent injections or higher doses may be necessary.

Treatment of bleeding

The dose of octocog alfa is calculated depending on your body weight and the factor VIII levels to be achieved. The desired factor VIII level depends on the location and severity of the bleeding.

Dose (IU) = body weight (kg) x desired factor VIII increase (% of normal) x 0.5

If you have the impression that ADVATE is not working properly, talk to your doctor.

Your doctor will perform appropriate laboratory tests to ensure that you have adequate factor VIII levels. This is especially important if you are having major surgery.

Use in children and adolescents (from 0 to 18 years)

When it comes to treating bleeding, the dose for children is the same as for adult patients. When it comes to preventing bleeding in children under 6 years of age, a dose of 20 to 50 IU per kg body weight is recommended 3 to 4 times a week. Administration of ADVATE to children ( intravenously ) does not differ from administration to adults. A central venous access device may be required to enable frequent infusion of factor VIII products.

Due to the reduced injection volume of ADVATE reconstituted in 2 ml, there is even less time to react to hypersensitivity reactions. Therefore, caution is recommended when injecting ADVATE reconstituted in 2 ml, especially for children.

How ADVATE is given

ADVATE is usually injected into a vein ( intravenously ) by your doctor or nurse. You or someone else can also give ADVATE as an injection, but only after the necessary training. Detailed instructions on how to give yourself the medicine can be found at the end of this leaflet.

If you use more ADVATE than you should 

Always take ADVATE exactly as your doctor has told you. Consult a doctor if you are unsure. If you inject more ADVATE than recommended, tell your doctor as soon as possible.

If you forget to take ADVATE

Do not inject a double dose to make up for a forgotten dose. Take the next dose as planned and continue according to your doctor’s prescription.

If you stop taking ADVATE

Do not stop using ADVATE without consulting your doctor

If you have any further questions on the use of this product, ask your doctor.

4. Possible side effects

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

If severe, sudden allergic (anaphylactic) reactions occur, discontinue injection immediately. You must contact your doctor immediately if you get any of the following early signs of allergic reactions:

  • rash, hives, general itching,
  • swelling of the lips and tongue,
  • difficulty breathing, wheezing, pressure over the chest,
  • general malaise,
  • dizziness, unconsciousness.


Severe symptoms, such as difficulty breathing and fainting, require immediate emergency treatment.

In children who have not been previously treated with factor VIII drugs, it is very common for inhibitory antibodies to develop (see section 2) (affects more than 1 user in 10). However, for patients who have previously been treated with factor VIII(treatment for more than 150 days), the risk is less and the complication is less common (occurs in less than 1 in 100 users). If you or your child develop antibodies, the medicines may stop working properly and you or your child may suffer from persistent bleeding. If this happens, consult a doctor immediately.

A very common side effect is (occurring in more than 1 in 10)

Factors VIII inhibitors (in children not previously treated with factor VIII medicines).

Common adverse s (affects up to 1 in 10)

Headache and fever.

Less common side effects are (affects up to 1 in 100)

Inhibitors of factor VIII (in patients who have been treated with factor VIII -previously (treatment for more than 150 days)), dizziness, influenza, fainting, abnormal heart rhythm, red itchy lumps on the skin, chest discomfort, bruising at the injection site, reaction to the injection site, itching, increased sweating, unusual taste in the mouth, swelling, migraine, memory problems, chills, diarrhea, nausea, vomiting, shortness of breath, sore throat, infection of the lymph vessels, pallor, eye inflammation, eczema, profuse sweating, swollen legs, feet decreased proportion of red blood cells in the blood, increased number of a certain type of white blood cells ( monocytes ) and pain in the upper abdomen or lower chest.

In connection with surgery

catheter-related infection, decreased red blood cell count, swelling of extremities joints, prolonged bleeding after drainage removal, decreased factor VIII level, and postoperative bruising.

In connection with the device for central venous access

Catheter-related infection, systemic infection, and local blood clot at the catheter site.

Adverse reactions with an unknown frequency (cannot be calculated from the available data).

Potentially life-threatening reactions ( anaphylaxis ) and other allergic reactions (hypersensitivity), general symptoms (fatigue, weakness).

Additional side effects are in children

In addition to the development of inhibitors in pediatric patients not previously treated, as well as catheter-related complications, no age-specific differences in adverse reactions were observed during clinical trials.

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 to the Medical Products Agency, www.lakemedelsverket.se. By reporting side effects, you can help increase drug safety information.
