WHAT IS IN THIS LEAFLET

This leaflet answers some common questions about gammanorm®. It does not contain complete information about gammanorm®. It does not take the place of talking to your doctor. If you have any concerns about using this product, ask your doctor. Follow your doctor's advice even if it is different from what this leaflet says.

Please read this leaflet carefully and keep it for future reference. However, the information in this leaflet is subject to change. Please check with your doctor whether there is any new information about this product that you should know since you were last treated with this product.

WHAT GAMMANORM IS USED FOR

gammanorm® is prepared from blood obtained from donors. gammanorm® contains proteins known as antibodies which can provide protection against some infections.

gammanorm® is used to treat patients who need replacement of antibodies due to an inherited disease (where antibody levels are low) or in other diseases where a lack of antibodies may cause frequent infections.

Ask your doctor if you have any questions about why gammanorm® has been prescribed for you. Your doctor will have assessed the risks and benefits for you associated with the use of this product.

BEFORE YOUR DOCTOR GIVES YOU GAMMANORM

Special Warning

This product is made from human plasma obtained from donors. 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 the blood and plasma donors to make sure those at risk of carrying infections are excluded, and the testing of each donation and pools of plasma for signs of virus/infections. Manufacturers of these products also include steps in the processing of the blood or plasma that can inactivate or remove the viruses. Despite these measures, when medicines prepared from human blood or plasma are administrated, the possibility of passing on infection cannot be totally excluded. This also applies to any unknown or emerging viruses or other types of infections and theoretically to Creutzfeldt-Jacob Disease (CJD) agents.

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.

Immunoglobulins have not been associated with hepatitis A or parvovirus B19 infections possibly because the antibodies against these infections, which are contained in the product, are protective.

Vaccines are available against some of these viruses and your doctor will be able to help you decide whether it is worthwhile having any of those vaccines.

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

Please discuss the risks and benefits of this product with your doctor.

gammanorm® must not be used if you have a history of allergy to this product or other human immunoglobulin products. Tell your doctor if you have allergies to any other medicines, or if you have ever had an allergic reaction to an injection.

Tell your doctor also if you:

  • have previously been advised that you have Immunoglobulin A (IgA) deficiency
  • suffer from a blood disorder or blood clotting problem
  • are taking or using any other medicines. These include medicines bought from pharmacies, supermarkets and health food stores
  • have any other medical conditions
  • are pregnant or breast-feeding
  • become pregnant during your treatment
  • have had any vaccination within the last two weeks or intend to receive one in the next three months

If you want further information, consult your doctor.

HOW TO USE GAMMANORM

gammanorm® should be given as a subcutaneous (under the skin) infusion. Treatment should be started by a doctor experienced with subcutaneous immunoglobulin. The dosage and infusion speed will be determined by your doctor, who will adapt the dose especially for you. If a large volume of product is required, you may receive more than one infusion.

Should your doctor decide that treatment at home is appropriate, your doctor will ensure that you receive training and precise information on using the infusion pump, infusion technique, keeping a treatment diary, and what action to take in the event of serious side effects. As soon as you are able to treat yourself, and if no side effects have arisen during treatment, your doctor may allow you to continue treatment at home. Always follow your doctor’s instructions.

In special cases where gammanorm® cannot be given subcutaneously, it may be administered intramuscularly (into muscle). An intramuscular injection must be given by a doctor or nurse.

Instructions

Always use gammanorm® as instructed by your doctor. Consult your doctor if you are uncertain.

The product should be at room or body temperature prior to use.

The solution should be clear or semi-translucent. Do not use solution that is cloudy, contains particles, or has deposits.

Handling instructions:

  • Remove the protective cap from the vial and wipe the rubber stopper with alcohol.
  • For withdrawing gammanorm, use a sterile syringe and needle or a transfer device (e.g. Minispike® or Medimop® vial adapter).
  • Inject air into the vial that is equivalent to the amount of gammanorm® to be withdrawn. Then withdraw gammanorm® from the vial. If multiple vials are required to achieve the desired amount of gammanorm®, repeat this step.
  • Follow the manufacturer’s instructions for preparing the pump. Prime the administration tubing to ensure that no air is left in the tubing by filling the tubing/needle with gammanorm®.
  • Clean the injection site(s) with antiseptic solution.
  • Grasp the skin between two fingers and insert the needle into the subcutaneous tissue.
  • gammanorm® must not be injected into a blood vessel. To test that no blood vessel has been accidentally hit, gently pull back on the syringe plunger and look to see if any blood is flowing back into the tubing. If you see any blood, remove and discard the needle and tubing. Repeat priming and needle insertion steps using a new needle, tubing and a new infusion site.
  • Secure the needle in place by applying sterile gauze or transparent dressing.
  • Infuse gammanorm® following the manufacturer’s instructions for the pump.
  • The infusion site should be changed after 5 - 15 ml.
  • Multiple injection sites can be used simultaneously. Injection sites should be at least 5 cm apart.
  • Remove the peel-off label from the gammanorm® vial and insert into the patient diary.

Unwanted effects

Along with their intended effects, blood products occasionally cause unwanted effects, some of which are serious. Individuals may also react differently to similar doses of the same medicine. Most minor effects are related to the rate of infusion and disappear when the rate is slowed down or the infusion stopped.

Do not be alarmed by the following list of side effects, you may not experience any of them. You should tell your doctor as soon as possible if you do not feel well while you are being given this medicine.

Common side effects of gammanorm® are local reactions at the injection site such as swelling, tenderness, pain, redness, hardening, a sensation of heat, itching, bruising, or rashes.

Side effects such as low blood pressure and allergic reactions may occasionally occur. In very rare cases, headache, dizziness, nausea, vomiting, moderate pain in the lower back, joint pains, fever, shivering, tiredness and anaphylactic shock (severe hypersensitivity reaction) have been reported.

If you experience any of the above mentioned effects or if you are worried about any other symptoms after administration, consult your doctor or pharmacist.

gammanorm® can interfere with some live vaccines (eg. measles, mumps, rubella and polio), even up to three months later. Advise your doctor if you are to receive other vaccines within three months of receiving gammanorm®.

gammanorm® can also interfere with some blood tests. Advise your doctor if you are to be tested after receiving gammanorm®.

For information on viral safety see BEFORE YOUR DOCTOR GIVES YOU gammanorm®.

Overdose (if you take too much)

As gammanorm® is usually given to you under the supervision of your doctor or trained medical professional, it is very unlikely that you will receive an overdose. If you experience several side effects, tell your doctor immediately and your doctor will know what to do.

Although the consequences of an overdose are unknown, it is recommended not to exceed the advised dosage.

Pharmacology

Pharmacodynamic properties.

ATC code.

J06BA01.
Human normal immunoglobulin contains the IgG antibodies present in the normal population, with a broad spectrum of antibodies against infectious agents. Gammanorm has a distribution of IgG subclasses closely proportional to that in native human plasma. Adequate doses of Gammanorm may restore abnormally low IgG levels to the normal range.

Pharmacokinetic properties.

With subcutaneous administration of human normal immunoglobulin, peak levels are achieved in the recipient's circulation after approximately 4-6 days.
In a clinical study the kinetics of IgG and IgG subclasses were studied in 23 patients with common variable immunodeficiency (CVID) who received human normal immunoglobulin subcutaneously (SC) at a dose of 100 mg/kg/week for a period of 18 months. Seventeen of these patients had been treated previously by the IM or IV routes. Out of these 17 patients, 11 were treated with weekly infusions (100 mg/kg/week) (group I), while in 6 (group II) the treatment was carried out as daily infusions (100 mg/kg/day) for 5 consecutive days during the first week (100 mg/kg/day) of treatment and then as weekly infusions thereafter (100 mg/kg/week). The remaining 6 patients had never been treated with any form of gammaglobulin (group III); these patients received weekly SC infusions (100 mg/kg/week).
The following results were achieved for this study: see Table 1.
Stable steady-state levels of IgG were obtained after one week in the subgroup of patients who received daily infusions for 5 days (group II).
These data show that trough levels can be maintained with dosing regimens of 100 mg/kg once a week.
With intramuscular administration, human normal immunoglobulin is bioavailable in the recipient's circulation after a delay of 2-3 days.
IgG and IgG complexes are broken down in the cells of the reticuloendothelial system.

Clinical Trials

Studies in patients with primary hypogammaglobulinaemia.

Twenty five (25) adult patients with unspecified primary hypogammaglobulinaemia were treated with human normal immunoglobulin (100 mg/kg/week, 34 to 40 mL/hour) for between 10 and 46 months. Patients were aged between 18 and 73 years (mean: 43 years); 10 men and 15 women took part in the study. After 6 months of SC therapy, the serum IgG concentrations were similar to those obtained after IV infusion and the median value was within the normal range.
In a second study, performed at multiple centres, 165 patients with primary immunodeficiency were followed during SC IgG replacement therapy for between 5 months and over 9 years (median treatment time was 3 years). The 69 women and 96 men enrolled in the study were aged between 13 and 76 years (mean: 43 years). The study population included patients with CVID (n = 101), X-linked agammaglobulinaemia (XLA, n = 7) and IgG subclass deficiencies with (n = 5) or without (n = 52) concurrent IgA deficiency. The mean doses at the 4 participating centres were between 220 and 465 mg/kg/month, administered once weekly in most patients.
In the study population with CVID or XLA a significant correlation was found between the monthly immunoglobulin doses given and the serum IgG levels reached after 6 months on SC therapy.

Study in patients with secondary hypogammaglobulinaemia.

Seventeen (17) patients with secondary immunodeficiency were treated subcutaneously with normal human immunoglobulin (50 mg/kg/week). After 6 months of therapy mean serum IgG levels increased from 3.1 g/L to 5.5 g/L. Higher doses could be used to achieve IgG levels within the normal range.
The time spent in hospital due to infections decreased from 272 days to 112 days in 11 of the 17 patients. The therapy was associated with a significant reduction in the number of hospital admissions due to infection and in the number of courses of antibiotic treatment compared with before treatment.

Study in children with hypogammaglobulinaemia.

Eight (8) children with immunodeficiency were treated subcutaneously with normal human immunoglobulin for an average of 3 years (range 1.5 to 6 years).
In total, approximately 1100 infusions were given. The patients received immunoglobulin doses ranging from 58 mg/kg/week to 149 mg/kg/week (mean 97 mg/kg/week) and achieved serum levels of IgG of between 5.2 g/L and 9.6 g/L. Diagnosis, age, dose and serum IgG levels in children treated with SC immunoglobulin transfusions at home are given in Table 2.

Indications

Replacement therapy in adults and children with primary immunodeficiency syndromes such as:
congenital agammaglobulinaemia and hypogammaglobulinaemia;
common variable immunodeficiency;
severe combined immunodeficiencies;
IgG subclass deficiencies with recurrent infections.
Replacement therapy in myeloma or chronic lymphatic leukaemia with severe secondary hypogammaglobulinaemia and recurrent infections.

Contraindications

Hypersensitivity to homologous immunoglobulins, especially in very rare cases of IgA deficiency, when the patient has antibodies against IgA. Gammanorm is contraindicated in any patient who has a history of allergic reaction to any human immunoglobulin preparation or hypersensitivity to any constituent of the product.
Gammanorm must not be administered intramuscularly in cases of severe thrombocytopenia and in other disorders of haemostasis.

Precautions

Gammanorm is made from human plasma. Products made from human plasma may contain infectious agents that can cause disease, such as viruses and theoretically Creutzfeldt-Jacob Disease (CJD) agents.
Standard measures to prevent infections resulting from the use of plasma-derived products include:
i. selection of donors;
ii. screening of individual donations and plasma pools for specific markers of infection; and
iii. the inclusion of effective manufacturing steps for the inactivation/removal of viruses.
The viral inactivation/removal steps for Gammanorm include solvent-detergent treatment and ethanol precipitation step.
Despite this, when plasma-derived products are administered, the possibility of transmitting infective agents cannot be totally excluded. This also applies to unknown or emerging viruses and other pathogens.
The measures taken are considered effective for enveloped viruses such as HIV, HBV and HCV.
The measures taken may be of limited value against non-enveloped viruses such as HAV and parvovirus B19. Parvovirus B19 may cause serious reactions in pregnant women who are sero-negative (foetal infection) and for individuals with immunodeficiency or increased red cell production (e.g. in haemolytic anaemia); however, there is reassuring clinical experience regarding the lack of hepatitis A or parvovirus B19 transmission with immunoglobulins and it is also assumed that the antibody content makes an important contribution to the viral safety.
Vaccination for patients in receipt of medicinal products made from human plasma should be considered where appropriate.
It is strongly recommended that every time that Gammanorm is administered to a patient, the name and batch number of the product are recorded in order to maintain a link between the patient and the batch of the product.
Gammanorm does not protect against hepatitis A.
Gammanorm must not be administered intravenously. If Gammanorm is accidentally administered into a blood vessel, patients could develop shock. In case of shock, the current medical standards for shock treatment should be observed.
For intramuscular administration, care should be taken to draw back the plunger of the syringe before injection to ensure that the needle is not in a blood vessel.
The recommended infusion rate should be adhered to (see Dosage and Administration). Patients should be closely monitored and carefully observed for any adverse events throughout the infusion period and for at least 20 minutes after the infusion.
Certain adverse drug reactions may occur more frequently in patients who receive human normal immunoglobulin for the first time or, in rare cases, when the human normal immunoglobulin product is switched or when treatment has been stopped for more than eight weeks.

Hypersensitivity.

True hypersensitivity reactions are rare. They can particularly occur in the very rare cases of IgA deficiency with anti-IgA antibodies. These patients should be treated with caution.
Rarely, human normal immunoglobulin can induce a fall in blood pressure with anaphylactic reaction, even in patients who have tolerated previous treatment with human normal immunoglobulin.
Potential complications can often be avoided by ensuring that:
i. patients are not sensitive to human normal immunoglobulin by first injecting the product slowly (see Dosage and Administration);
ii. patients are carefully monitored for any symptoms throughout the infusion period. In particular, patients naïve to human normal immunoglobulin, patients switched from an alternative product or when there has been a long interval since the previous infusion should be monitored during the first infusion and for the first hour after the first infusion, in order to detect potential adverse signs. All other patients should be observed for at least 20 minutes after administration.
Suspicion of allergic or anaphylactic type reactions requires immediate discontinuation of the injection. In case of shock, the current medical standards for shock treatment should be observed.

Thromboembolism.

Arterial and venous thromboembolic events including myocardial infarction, stroke, deep venous thrombosis and pulmonary embolism have been associated with the use of immunoglobulins.
Patients should be sufficiently hydrated before use of immunoglobulins. Caution should be exercised in patients with pre-existing risk factors for thrombotic events (such as advanced age, hypertension, diabetes mellitus and a history of vascular disease or thrombotic episodes, patients with acquired or inherited thrombophilic disorders, patients with prolonged periods of immobilisation, severely hypovolemic patients, patients with diseases which increase blood viscosity).
Patients should be informed about first symptoms of thromboembolic events including shortness of breath, pain and swelling of a limb, focal neurological deficits and chest pain and should be advised to contact their physician immediately upon onset of symptoms.

Use in pregnancy.

The safety of Gammanorm for use in human pregnancy has not been established. Clinical experience with immunoglobulins suggests that no harmful effects on the course of pregnancy, or on the foetus and the neonate are to be expected.

Use in lactation.

The safety of immunoglobulin G for use during lactation has not been established.

Genotoxicity.

No studies have been conducted.

Carcinogenicity.

No studies have been conducted.

Effects on ability to drive and use machines.

No effects on ability to drive and use machines have been observed.

Interactions

Immunoglobulin administration may impair for a period of at least six weeks and up to three months the efficacy of live attenuated virus vaccines such as measles, rubella, mumps and varicella.
After administration of this product, an interval of three months should elapse before vaccination with live attenuated virus vaccines. In the case of measles, this impairment may persist for up to one year. Therefore patients receiving measles vaccine should have their antibody status checked.

Effects on laboratory tests.

After injection of immunoglobulin, the transitory rise of the various passively transferred antibodies in the patient's blood may result in misleading positive results in serological testing.
Passive transmission of antibodies to erythrocyte antigens, e.g. A, B or D may interfere with some serological tests (e.g. reticulocyte count, haptoglobin and Coombs test).

Adverse Effects

Adverse reactions for Gammanorm are rare. In case of severe reactions, the infusion should be stopped and an appropriate treatment should be initiated.
The following adverse reactions have been observed with Gammanorm: see Table 3.
Cases of exfoliative dermatitis have been observed with human normal immunoglobulin products.
When large doses are given, it is advisable to administer them in divided doses at different sites.
For information on viral safety, see Precautions.

Dosage and Administration

Replacement therapy.

Treatment should be initiated and monitored under the supervision of a physician experienced in the treatment of immunodeficiency.
The dosage may need to be individualised for each patient dependent on the pharmacokinetic and clinical response. The following dosage regimens are given as guidance.
The dosage regimen should achieve a sustained level of immunoglobulin G (IgG). A loading dose of at least 0.2-0.5 g/kg may be required. After steady-state IgG levels have been attained, maintenance doses are administered at repeated intervals to reach a cumulative monthly dose of the order of 0.4-0.8 g/kg.
Trough levels should be measured in order to adjust the dose and dosage interval.
For intramuscular administration see below.

Administration.

Gammanorm should be administered via the subcutaneous or intramuscular route. In exceptional cases, where subcutaneous administration may not be applicable, low doses of Gammanorm can be administered via the intramuscular route.

Subcutaneous infusion for home treatment.

Home treatment should be initiated by a physician experienced in the guidance of patients for home treatment. The patient will be instructed in the use of a syringe driver, infusion techniques, the keeping of a treatment diary and measures to be taken in the case of severe adverse events.

Subcutaneous infusion with pump.

A common dose is 0.6 mL (100 mg) Gammanorm per kg bodyweight once a week, which may be administered at several infusion sites. Initial infusion rate: 10 mL/hour/pump. The infusion rate may be gradually increased by 1 mL/hour/pump every three to four weeks. The maximum dose administered has been 40 mL/hour using two pumps simultaneously.
When large doses are given, it is advisable to administer them in divided doses at different sites.

Intramuscular injection.

Intramuscular injection must be given by a physician or nurse.

Paediatric patients.

In children suffering from PID, as with adults, trough levels should be measured in order to adjust the dose and dosage interval. After steady-state IgG levels have been attained, maintenance doses of about 80 to 100 mg/kg/week are usually administered to reach a cumulative monthly dose of the order of 0.4-0.8 g/kg. If home treatment is considered, advice from a physician experienced in the guidance of patients for home treatment should be sought. The patient's parents should be instructed in the use of the application device, infusion techniques, the keeping of a treatment diary and measures to be taken in case of severe adverse events.

Instructions for use, handling and disposal.

Gammanorm should be brought to room or body temperature before use.
The solution should be clear or slightly opalescent and colourless or pale yellow or light brown. Do not use solutions that are cloudy or have deposits.

Handling instructions.

Remove the protective cap from the vial and wipe the rubber stopper with alcohol.
For withdrawing Gammanorm, use a sterile syringe and needle or a transfer device (e.g. Minispike or Medimop vial adapter).
Inject air into the vial that is equivalent to the amount of Gammanorm to be withdrawn. Then withdraw Gammanorm from the vial. If multiple vials are required to achieve the desired amount of Gammanorm, repeat this step.
Follow the manufacturer's instructions for preparing the pump. Prime the administration tubing to ensure that no air is left in the tubing by filling the tubing/ needle with Gammanorm.
Clean the injection site(s) with antiseptic solution.
Grasp the skin between two fingers and insert the needle into the subcutaneous tissue.
Gammanorm must not be injected into a blood vessel. To test that no blood vessel has been accidentally hit, gently pull back on the syringe plunger and look to see if any blood is flowing back into the tubing. If you see any blood, remove and discard the needle and tubing. Repeat priming and needle insertion steps using a new needle, tubing and a new infusion site.
Secure the needle in place by applying sterile gauze or transparent dressing.
Infuse Gammanorm following the manufacturer's instructions for the pump.
The infusion site should be changed after 5-15 mL.
Multiple injection sites can be used simultaneously. Injection sites should be at least 5 cm apart.
Remove the peel off label from the Gammanorm vial and insert into the patient diary.
The product does not contain an antimicrobial agent. It must, therefore be used immediately after opening the vial. Product is for single use in one patient only. Any unused product or waste material should be disposed of in accordance with local requirements.
