1. What Privigen is and what it is used for
What Privigen is
Privigen belongs to the class of medicines called human normal immunoglobulins. Immunoglobulins are also known as antibodies and are blood proteins that help your body to fight infections.
How Privigen works
Privigen contains immunoglobulins that have been prepared from the blood of healthy people. The medicine works in exactly the same way as the immunoglobulins naturally present in human blood of healthy people.
What Privigen is used for
Privigen is used for the treatment of adults and children (0-18 years) in the following situations:
A) to increase abnormally low immunoglobulin levels in your blood to normal levels (replacement therapy). There are five groups:
1. Patients who are born with a reduced ability or inability to produce immunoglobulins (primary immunodeficiencies (PID)).
2. Patients with blood cancer (chronic lymphocytic leukaemia) who have low immunoglobulin levels in the blood (hypogammaglobulinaemia) and develop recurrent infections and for whom preventative antibiotics have failed.
3. Patients with bone marrow cancer (multiple myeloma) who have low immunoglobulin levels in the blood and develop recurrent infections, if no immune response is obtained after vaccination against certain bacteria (pneumococci).
4. Patients who have low immunoglobulin levels in the blood after transplantation of stem cells from another person.
5. Patients with inborn AIDS (Acquired Immunodeficiency Syndrome) and recurrent infections.
B) to treat certain inflammatory disorders (immunomodulation). There are four groups:
1. Patients who do not have enough blood platelets (primary immune thrombocytopenia (ITP)) and who are at high risk of bleeding or will have surgery in the near future.
2. Patients with Guillain-Barré syndrome. This is an acute disease that is characterised by inflammation of the peripheral nerves that causes severe muscle weakness mainly in the legs and upper limbs.
3. Patients with Kawasaki disease. This is an acute disease that primarily affects young children. It is characterised by inflammation of blood vessels throughout the body.
4. Patients with chronic inflammatory demyelinating polyneuropathy (CIDP). This is a chronic disease that is characterised by inflammation of the peripheral nerves that causes muscle weakness and/or numbness mainly in the legs and upper limbs.
2. What you need to know before you are given Privigen
Read this section carefully. The information given should be taken into consideration by you and your doctor before you are given Privigen.
Do NOT take Privigen
if you are allergic to human immunoglobulins or to proline.
if you have developed antibodies against immunoglobulins of the type IgA in your blood.
if you suffer from hyperprolinaemia type I or II (a genetic disorder causing high levels of the amino acid proline in the blood). This is an extremely rare disorder. Only a few families with this disease are known worldwide.
Warnings and precautions
Which circumstances increase the risk of having side effects?
Tell your doctor or healthcare professional prior to treatment if any of the circumstances listed below applies to you:
You receive this medicine in high doses either on 1 day or over several days and you have a blood group A, B or AB and/or you have an underlying inflammatory condition. In these circumstances, it has been commonly reported that immunoglobulins increase the risk of breakdown of red blood cells (haemolysis).
You are overweight, are elderly, have diabetes, have been bedridden for a long time, have high blood pressure, have low blood volume (hypovolaemia), have problems with your blood vessels (vascular diseases), have an increased tendency for blood clotting (thrombophilia or thrombotic episodes) or have a disease or a condition which causes your blood to thicken (hyperviscous blood). In these circumstances, immunoglobulins may increase the risk of heart attack (cardiac infarction), stroke, blood clots in the lung (lung embolism), or blockage of a blood vessel in the leg, although only very rarely.
You are diabetic. Although Privigen does not contain sugar, it may be diluted with a special sugar solution (5% glucose), which could affect your blood sugar level.
You have or had previously problems with your kidneys or take medicinal products that may harm your kidneys (nephrotoxic medicinal products). In these circumstances, immunoglobulins may increase the risk of serious rapid loss of kidney function (acute renal failure) although only very rarely. Loss of kidney function with fatal outcome has occurred in isolated haemolysis-related cases.
What kind of monitoring is required during the infusion?
For your personal safety, treatment with Privigen will take place under the supervision of your doctor or healthcare professional. You will usually be observed during the whole infusion and for at least 20 minutes thereafter. In certain circumstances, special precautions may be necessary. Examples of such circumstances are:
you are receiving Privigen at a high infusion rate or
you are receiving Privigen for the first time or after a long break in treatment (e.g. several months).
In these cases you will be closely observed during the whole infusion and for at least 1 hour afterwards.
When may slowing or stopping the infusion be required?
You may be allergic (hypersensitive) to immunoglobulins without knowing it. However, true allergic reactions are rare. They may occur even if you have previously received human immunoglobulins and had tolerated them well. It may happen particularly if you have developed antibodies against immunoglobulins of the type IgA. In these rare cases allergic reactions such as a sudden fall in blood pressure or shock may occur (see also section 4 “Possible side effects”).
In very rare cases, transfusion-related acute lung injury (TRALI) can occur after receiving immunoglobulins including Privigen. This will lead to non-heart related accumulation of fluid in the air spaces of the lungs (non-cardiogenic pulmonary oedema). You will recognize TRALI by severe difficulty in breathing (respiratory distress), abnormally low level of oxygen in the blood (hypoxemia), normal heart function (left ventricular function) and increased body temperature (fever). Symptoms typically appear within 1 to 6 hours after receiving treatment.
Tell your doctor or healthcare professional immediately if you notice such reactions during the infusion of Privigen. He or she will decide whether to decrease the infusion rate or to stop the infusion completely.
Blood tests
Tell your doctor about your treatment with Privigen prior to having any blood tests.
After receiving Privigen, the results of certain blood tests (serological tests) may be impaired for a certain time.
Information on safety with respect to infections
Privigen is made from human blood plasma (this is the liquid part of the 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 and 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, and for the non-enveloped hepatitis A virus and parvovirus B19.
Immunoglobulins have not been associated with hepatitis A or parvovirus B19 infections, possibly because antibodies against these infections, which are contained in the product, are protective.
It is strongly recommended that every time you are given a dose of Privigen the name and batch number of the product are recorded in order to maintain a record of the batches used.
Other medicines and Privigen
Tell your doctor or healthcare professional if you are using, have recently used or might use any other medicines.
Vaccinations
Tell your vaccinating doctor prior to a vaccination about your treatment with Privigen.
After receiving Privigen, the efficacy of certain vaccinations may be impaired. Affected are vaccinations with live attenuated virus vaccines such as vaccinations against measles, mumps, rubella and varicella. Such vaccinations should be postponed for at least 3 months after the last infusion of Privigen. In the case of measles vaccinations the impairment may persist for up to 1 year. Therefore, your vaccinating doctor should check the effectiveness of the measles vaccination.
Pregnancy and breast-feeding
Tell your doctor or healthcare professional if you are pregnant, plan to become pregnant or are breast-feeding. Your doctor will decide whether you can receive Privigen during your pregnancy or while you are breast-feeding.
Medicines containing antibodies have been used in pregnant and breast-feeding women. Long-term experience has shown that no harmful effects during the course of the pregnancy or to the newborn are to be expected.
If you receive Privigen while you are breast-feeding the antibodies in this medicine will also be found in the breast milk. Thus, also your baby can receive the protective antibodies.
Driving and using machines
Patients may experience effects, such as dizziness or nausea, during treatment with Privigen that might affect the ability to drive and use machines. If this happens, you should not drive or use machines until these effects have disappeared.
Privigen contains proline
You must not take it if you suffer from hyperprolinaemia (see also section 2 “What you need to know before you are given Privigen”).
Tell your doctor prior to treatment.
3. How to use Privigen
Privigen is intended solely for the infusion into a vein (intravenous infusion). It is usually administered by your doctor or healthcare professional.
Your doctor will calculate the correct dose for you taking into account your weight, the specific circumstances listed under section 2 “Warnings and precautions” and response to treatment. The dose calculation for children and young patients is not different from that for adults. At the beginning of the infusion you will receive Privigen at a slow infusion rate. If you tolerate this well, your doctor can gradually increase the infusion rate.
If you receive more Privigen than you should
Overdose is very unlikely to occur because Privigen is usually administered under medical supervision. If, in spite of this, you receive more Privigen than you should, your blood may become too thick (hyperviscous), which might increase the risk of developing blood clots.
This may happen particularly if you are a patient at risk, for example if you are elderly or if you suffer from a heart or kidney disease. Tell your doctor if you are known to have medical problems.
4. Possible side effects
Like all medicines, this medicine can cause side effects, although not everybody gets them.
Possible side effects may be reduced or even avoided by infusing Privigen at a slow infusion rate. Such side effects may occur even if you have previously received human immunoglobulins and tolerated them well.
In rare and isolated cases, the following side effects have been reported with immunoglobulin preparations:
severe hypersensitivity reactions such as a sudden fall in blood pressure or anaphylactic shock (e.g. you may feel light-headed, dizzy, faint on standing, cold in the hands and feet, sense an abnormal heart beat or chest pain, or have blurred vision) even when you have shown no hypersensitivity on previous infusions,
Tell your doctor or healthcare professional immediately if you notice such signs during the infusion of Privigen. He or she will decide whether to decrease the infusion rate or to stop the infusion completely.
formation of blood clots which may be carried off in the blood circulation (thromboembolic reactions) and which may result e.g. in myocardial infarction (e.g. when you have sudden chest pain or shortness of breath), stroke (e.g. when you have a sudden onset of muscle weakness, have loss of sensation and/or balance, decreased alertness or difficulty in speaking), blood clots in the arteries of the lungs (e.g. when you have chest pain, difficulty in breathing or are coughing up blood), deep vein thrombosis (e.g. when you have redness, feel warmth, pain, tenderness, or have a swelling of one or both legs),
chest pain, chest discomfort, painful respiration due to transfusion related lung injury (TRALI)
Tell your doctor or healthcare professional immediately if you have any of the above symptoms. Anyone experiencing such symptoms should immediately be transported to a hospital emergency room for eva luation and treatment.
