What Normal Immunoglobulin-VF is used for

Normal Immunoglobulin-VF is manufactured from human plasma (the liquid component of blood) collected by Australian Red Cross Lifeblood. Normal Immunoglobulin-VF contains protein substances called antibodies which can provide protection against some infectious diseases. It can prevent infection if given to people with low levels of antibodies.

Normal Immunoglobulin-VF is used to treat conditions where low antibody levels in the blood are inherited, and in other diseases where a lack of antibody may cause frequent infections.

It is also used to prevent infection by viruses such as poliomyelitis, hepatitis A, and measles in those coming in contact with a source of infection, such as family members.

Ask your doctor if you have any questions about why Normal Immunoglobulin-VF has been prescribed for you. Your doctor will have assessed the risks and benefits associated with the use of this medicine for you.

Before you are given Normal Immunoglobulin-VF

Normal Immunoglobulin-VF must not be used if you have a history of allergy to this medicine. 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
are taking or using any other medicines. These include medicines bought from pharmacies, supermarkets and health food stores.
have had any vaccination during the last two weeks
have a history of heart, or blood vessel disease, or blood clots, have thick blood, have been immobile for some time. Also tell the doctor what medicine you are using as some medicines such as those that contain the hormone estrogen (for example, birth control pills), may increase your risk of developing a blood clot.
have any other medical conditions.

Pregnant or lactating women should discuss use of Normal Immunoglobulin-VF with their doctor.

About blood products

When products are made from human blood and injected into you, it is possible that viruses or other substances could be present in the product and cause an illness. These could be viruses such as hepatitis, human immunodeficiency virus (HIV), or human parvovirus B19 and theoretically the Creutzfeldt-Jakob Disease (CJD) agent. There could also be other infectious agents some of which may not as yet have been discovered.

To reduce the risk of this happening, extra steps are taken when manufacturing this product. Strict controls are applied to the selection of blood donors and donations. The product is specially treated to remove and kill certain viruses. These special treatments are considered effective against viruses known as enveloped viruses such as HIV, hepatitis B virus and hepatitis C virus, and the non-enveloped viruses, such as hepatitis A virus and human parvovirus B19. Additionally, the product contains specific antibodies which can provide some protection against human parvovirus B19. Despite these measures, the risk of viral and other agent’s infectivity cannot be totally eliminated.

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.

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

How to use Normal Immunoglobulin-VF

Your doctor will determine the dose(s) of Normal Immunoglobulin-VF that you are to receive. Your doctor will give you the injection. It will be injected into the muscle. If a large volume of product is required, you may receive more than one injection.

Side effects

Along with their intended effects, medicines may cause some unwanted effects, which can sometimes be serious. Furthermore, individual patients may react differently to the same dose of the same medicine. This applies to Normal Immunoglobulin-VF.

Reactions are very uncommon after injection with Normal Immunoglobulin-VF. However, some pain, redness and stiffness may be apparent at the injection site. This may occur after any large injection into a muscle.

Occasionally mild fever, chills, drowsiness or discomfort may be felt and an itchy rash may develop.

If any of these effects are severe, or if you are worried about any other symptoms after the injection, consult your doctor.

Contact your doctor immediately if you experience signs and symptoms such as shortness of breath, chest pain, pain and swelling of a limb, weakness or numbness on one side of the body after receiving Normal Immunoglobulin-VF.

Normal Immunoglobulin-VF can interfere with some live vaccines (e.g. measles and polio), even up to three months later. Advise your doctor if you are to receive other vaccines within three months of receiving Normal Immunoglobulin-VF.

Overdose

The consequences of overdosage are not known.

Storing Normal Immunoglobulin-VF

Store at 2°C to 8°C (Refrigerate. Do not freeze). Protect from light.

Do not use after the expiry date shown on the label.

4 Clinical Particulars

4.1 Therapeutic Indications

Normal Immunoglobulin-VF is indicated in the management of congenital and acquired forms of primary hypogammaglobulinaemia. It may also be of value in treating secondary forms of this disorder as in leukaemia, nephrosis and acute protein-losing enteropathy, particularly when there is a tendency to recurrent infection.
In susceptible contacts of hepatitis A, measles and poliomyelitis, Normal Immunoglobulin-VF may be of value in preventing or modifying the disease. In general, the earlier in the incubation period of these diseases Normal Immunoglobulin-VF is given, the greater its effectiveness.

Hepatitis A.

Routine passive protection is recommended in persons exposed less than one week previously for the following categories of individuals:
Household contacts of an index case, who have not already had hepatitis A or have no serological evidence of immunity to the virus.
Common source exposures. When a vehicle such as food or water is identified as a common source of infection for multiple hepatitis cases, administration of Normal Immunoglobulin-VF should be considered for all those exposed to the source.
Institutional contacts.
Staff in institutions where hepatitis is endemic.
Routine prophylaxis is not recommended for school, office, factory or hospital contacts.

Rubella.

Although Normal Immunoglobulin-VF can prevent or modify the clinical disease in susceptible rubella contacts if given within 72 hours of exposure, it does not prevent viraemia in such patients. It should, therefore, not be relied upon to prevent congenital malformations due to rubella if given to susceptible pregnant women during the first trimester.

Measles (morbilli).

Normal Immunoglobulin-VF is indicated for protection against measles in persons exposed less than one week previously. It is recommended in children under six months of age whose mothers have not had the disease, in children between six months and three years of age who have not been actively immunised and in immunosuppressed contacts of the index case.

Poliomyelitis.

Normal Immunoglobulin-VF is recommended for susceptible contacts who have not been immunised against poliomyelitis.

4.2 Dose and Method of Administration

Dosage.

The following dosages are recommended:
Hepatitis A.

Household contacts, common source exposures.

A dose of Normal Immunoglobulin-VF equivalent to 0.06 mL/kg bodyweight should be given for long-term protection or 0.03 mL/kg bodyweight for short-term protection. For prophylaxis long-term, the injections should be given 5-monthly but serological checks should be made to assess if active immunity has developed.
The following doses of Normal Immunoglobulin-VF are recommended for persons who plan to travel in areas where hepatitis A is common*. Length of stay less than 3 months, 0.03 mL/kg bodyweight; 3 months or longer, 0.06 mL/kg bodyweight (repeat every 4-6 months).

Institutional contacts*.

0.06 mL/kg bodyweight.

Staff in institutions where hepatitis is endemic*.

A large dose (0.06 mL/kg bodyweight) should be offered at the time of employment, and this should be repeated at six-monthly intervals if the risk persists.
*The use of hepatitis A vaccine may be more appropriate for these individuals, provided there is adequate time for active immunity to develop (7-10 days).
Measles. 0.2 mL/kg bodyweight for prevention.
Poliomyelitis. 0.3 mL/kg bodyweight.
Hypogammaglobulinaemia. 0.6 mL/kg bodyweight at intervals of one month. An additional dose should be given during the first month of treatment.

Administration.

If the product appears to be turbid by transmitted light or contains any sediment, it must not be used. The product contains no antimicrobial preservative. It must, therefore, be used immediately after opening the vial. Any unused solution must be discarded appropriately.
Normal Immunoglobulin-VF should be brought to room temperature before use, and given slowly by deep intramuscular injection using an appropriate sized needle. If a large dose (more than 5 mL) is required, it is advisable to administer it in divided doses at different sites. Hyaluronidase and/or a suitable local anaesthetic may be added to the injection if desired.
An intravenous preparation is available from CSL when large doses of immunoglobulin need to be given, or when the patient has a significant haemostatic defect which may cause bleeding following intramuscular injection.

4.3 Contraindications

Normal Immunoglobulin-VF is contraindicated in individuals:
1. With isolated immunoglobulin A (IgA) deficiency, unless they have been tested and shown not to have circulating anti-IgA antibodies.
2. Who have severe thrombocytopenia or any coagulation disorder that would contraindicate intramuscular injections.

4.4 Special Warnings and Precautions for Use

Hypersensitivity.

Normal Immunoglobulin-VF must not be administered intravenously because of the potential for anaphylactic reactions. Injections must be made intramuscularly, and care should be taken to draw back on the plunger of the syringe before injection in order to be certain that the needle is not in a blood vessel.
Normal Immunoglobulin-VF should be given with caution to patients with a history of prior systemic allergic reactions following the administration of human immunoglobulin preparations. In the case of shock, treatment should follow the guidelines of shock therapy.

Thromboembolism.

Arterial and venous thromboembolic events including myocardial infarction, stroke, deep venous thrombosis and pulmonary embolism have been associated with the use of immunoglobulins. These events may be associated with Normal Immunoglobulin-VF when it is used for primary or secondary hypogammaglobulinaemia. 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 hypovolaemic 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.

Pathogen safety.

This product is made from human plasma. Products made from human plasma may contain infectious agents, such as viruses and theoretically Creutzfeldt-Jakob Disease (CJD) agents, that can cause disease. The risk that such products will transmit an infectious agent has been reduced by screening plasma donors for prior exposure to certain infectious agents and by testing for the presence of certain viral markers.
In addition, the manufacturing process for Normal Immunoglobulin-VF contains specific steps to reduce the possibility of viral transmission including pasteurisation for viral inactivation and nanofiltration for virus removal. The current procedures applied in the manufacture of this product are effective against enveloped viruses such as human immunodeficiency virus (HIV), hepatitis B virus (HBV) and hepatitis C virus (HCV), and the nonenveloped viruses, such as hepatitis A virus (HAV) and human parvovirus B19.
Additionally, the product contains specific antibodies directed against human parvovirus B19.
There is no evidence to date that parvovirus B19 can be transmitted by Normal Immunoglobulin-VF, which is known to contain antibodies to the virus and the nanofiltration step of the manufacturing process has been shown to remove such viruses (or viruses of similar size).
Immunoglobulins for intramuscular injection, prepared by this process from plasma screened by current methods, have not been implicated in the transmission of viral infectious diseases, including human immunodeficiency virus (HIV). Studies using plasma spiked with HIV have shown that the Cohn cold ethanol fractionation process produces a very large reduction in virus titre with undetectable levels in the immunoglobulin fraction. Epidemiological studies have not recognised any cluster of AIDS patients or HIV seroconversion in immunoglobulin recipients.
Despite these measures, such products may still potentially transmit disease. There is also the possibility that other known or unknown infectious agents may be present in such products.
Vaccination for patients in receipt of medicinal products from human plasma should be considered where appropriate.

Use in the elderly.

The use of this product in the elderly population has not been established in appropriate studies. To date, this population is not over-represented in spontaneous reports of adverse events associated with the use of CSL's intramuscular immunoglobulin products.

Paediatric use.

The use of this product in the paediatric population has not been established in appropriate studies. To date, this population is not over-represented in spontaneous reports of adverse events associated with the use of CSL's intramuscular immunoglobulin products.

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.

4.5 Interactions with Other Medicines and Other Forms of Interactions

Normal Immunoglobulin-VF should not be mixed with other pharmaceutical products, except as indicated (see Section 4.2 Dose and Method of Administration).

Live attenuated virus vaccines.

Passively acquired antibody can interfere with the response to live, attenuated virus vaccines. Therefore, administration of such vaccines, e.g. poliomyelitis or measles, should be deferred until approximately three months after passive immunisation. By the same token, immunoglobulins should not be administered for at least two weeks after a vaccine has been given.

Inactivated vaccines.

Inactivated vaccines may be administered concurrently with passive antibody (although in separate syringes) to induce active immunity as is sometimes done for tetanus-prone wounds.

4.6 Fertility, Pregnancy and Lactation

Effects on fertility.

No reproductive toxicity studies have been conducted with Normal Immunoglobulin-VF. There have been no reports of such effects associated with the use of CSL's plasma-derived therapeutic medicines.
The safety of this medicinal product for use in human pregnancy has not been established in controlled clinical trials. Normal Immunoglobulin-VF should therefore only be given with caution to pregnant women.
The safety of this medicinal product for use during lactation has not been established in controlled clinical trials. Normal Immunoglobulin-VF should therefore only be given with caution to breastfeeding mothers. Immunoglobulins are excreted in breast milk, however, it is not known whether this applies to passively administered Normal Immunoglobulin-VF.

4.7 Effects on Ability to Drive and Use Machines

The effects of this medicine on a person's ability to drive and use machines were not assessed as part of its registration.

4.8 Adverse Effects (Undesirable Effects)

Local tenderness, erythema and stiffness may occur at the site of injection and may persist for several hours. This may occur after any intramuscular injection. In the clinical trial with hepatitis B immunoglobulin, the following general and local reactions were recorded in the 58 healthy subjects (total number of events, up to and including 7 days postinjection; pasteurised/ unpasteurised product): malaise (20/22 events), drowsiness (13/17 events), induration (10/4 events), sensation of fever (4/4 events), chills (3/3 events), sweating (3/1 events) and warmth/ heat when touched (0/4 events). There was an overall higher reporting of local tolerance adverse events at the injection site for the unpasteurised product, such as pain (32/52 events), bruising (10/22 events), redness (2/8 events) and irritation (2/4 events).
Mild pyrexia, malaise, drowsiness and urticaria have been reported occasionally after injections of immunoglobulins. True allergic responses are rare. Skin lesions, headache, dizziness, nausea, generalised hypersensitivity reactions and convulsions have been reported on rare occasions.

Reporting suspected adverse effects.

Reporting suspected adverse reactions after registration of the medicinal product is important. It allows continued monitoring of the benefit-risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions at www.tga.gov.au/reporting-problems.

4.9 Overdose

The consequences of overdosage are not known.
For information on the management of overdose, contact the Poisons Information Centre on 13 11 26 (Australia).

5 Pharmacological Properties

5.1 Pharmacodynamic Properties

Mechanism of action.

Normal Immunoglobulin-VF consists mainly of IgG with a broad spectrum of antibodies against various infectious agents.

Clinical trials.

A comparative clinical trial was conducted to investigate the effect of pasteurisation on the in vivo behaviour of intramuscular immunoglobulins using hepatitis B immunoglobulin (pasteurised and unpasteurised) as the representative of this group of products.
Fifty-eight (58) healthy subjects (28 males and 30 females) each received an intramuscular injection of pasteurised (viral inactivated) or unpasteurised hepatitis B immunoglobulin. No significant clinical differences were observed.
Twenty-eight (28) subjects received the viral inactivated product. Maximal serum concentration of IgG was reached after 8.0 ± 5.5 days (mean ± SD), and the estimated half-life of IgG was 27.2 ± 6.6 days (mean ± SD). These values are consistent with ranges observed with other intramuscular immunoglobulin products.
A clinical trial with Normal Immunoglobulin-VF has not been conducted.

5.2 Pharmacokinetic Properties

See Section 5.1 Pharmacodynamic Properties.

5.3 Preclinical Safety Data
