3    PHARMACEUTICAL FORM

Suspension for injection in pre-filled syringe.

ADACEL appears as a cloudy white suspension.

4    CLINICAL PARTICULARS

4.1    Therapeutic indications

ADACEL is indicated for active immunization against tetanus, diphtheria and pertussis in persons from 4 years of age as a booster following primary immunization.

The use of ADACEL should be determined on the basis of official recommendations.

4.2    Posology and method of administration

Posology

A single injection of one (0.5 mL) dose is recommended in all indicated age groups.

ADACEL is a vaccine containing low-dose diphtheria-, tetanus- and pertussis-antigens indicated for booster vaccinations. When administering the vaccine, indications and dosing intervals according to the official recommendations should be considered for all antigens contained in the vaccine.

Individuals with an incomplete, or no history of a primary series of diphtheria and tetanus toxoids should not be vaccinated with ADACEL.

ADACEL is not precluded in persons with an incomplete, or no history of previous pertussis vaccination. However, a booster response will only be elicited in individuals who have been previously primed by vaccination or by natural infection.

There are currently no data upon which to base a recommendation for the optimal interval for administering subsequent booster doses with ADACEL.

ADACEL can be used in the management of tetanus prone injuries with or without concomitant administration of Tetanus Immunoglobulin according to official recommendations.

Paediatric population

Children from the age of 4 years onwards and adolescents should receive the same dosage as adults.

Method of administration

A single injection of one dose (0.5 mL) of ADACEL should be administered intramuscularly. The preferred site is into the deltoid muscle.

ADACEL should not be administered into the gluteal area; intradermal or subcutaneous routes should not be used (in exceptional cases the subcutaneous route may be considered, see section 4.4).

Precautions to be taken before handling or administering the medicinal product

For instructions on handling of the medicinal product before administration, see section 6.6.

4.3 Contraindications

ADACEL should not be administered to person with known hypersensitivity

-    to diphtheria, tetanus or pertussis vaccines

-    to any other component of the vaccine (see section 6.1)

-    to any residual substances carried over from manufacture (formaldehyde and glutaraldehyde), which may be present in undetectable trace amounts.

ADACEL should not be administered to persons who experienced an encephalopathy of unknown origin within 7 days of previous immunization with a pertussis-containing vaccine.

As with other vaccines, ADACEL should be postponed in persons suffering from an acute severe febrile illness. The presence of a minor infection is not a contraindication.

4.4 Special warnings and precautions for use

ADACEL should not be used for primary immunization.

Regarding the interval between a booster dose of ADACEL and preceding booster doses of diphtheria and/or tetanus containing vaccines, the official recommendations should generally be followed. Clinical data have demonstrated that there was no clinically relevant difference in rates of adverse reactions associated with administration of a tetanus-, diphtheria- and pertussis-containing booster vaccine as early as 4 weeks, compared to at least 5 years, after a preceding dose of tetanus and diphtheria-containing vaccine.

Prior to immunization

Vaccination should be preceded by a review of the person’s medical history (in particular previous vaccinations and possible adverse events). In persons who have a history of serious or severe reaction within 48 hours of a previous injection with a vaccine containing similar components, administration of ADACEL vaccine must be carefully considered.

As with all injectable vaccines, appropriate medical treatment and supervision should be readily available for immediate use in case of a rare anaphylactic reaction following the administration of the vaccine.

If Guillain-Barre syndrome or brachial neuritis has occurred following receipt of prior vaccine containing tetanus toxoid, the decision to give any vaccine containing tetanus toxoid should be based on careful consideration of the potential benefits and possible risks.

ADACEL should not be administered to persons with progressive neurological disorder, uncontrolled epilepsy or progressive encephalopathy until a treatment regimen has been established and the condition has stabilized.

The immunogenicity of the vaccine could be reduced by immunosuppressive treatment or immunodeficiency. It is recommended to postpone the vaccination until the end of such disease or treatment if practical. Nevertheless, vaccination of HIV infected persons or persons with chronic immunodeficiency, such as AIDS, is recommended even if the antibody response might be limited.

Administration precautions

Do not administer by intravascular or intradermal injection.

Intramuscular injections should be given with care in patients on anticoagulant therapy or suffering from coagulation disorders because of the risk of haemorrhage. In these situations administration of ADACEL by deep subcutaneous injection may be considered, although there is a risk of increased local reactions.

Other considerations

As with any vaccine, vaccination with ADACEL may not protect 100% of susceptible individuals.

A persistent nodule at the site of injection may occur with all adsorbed vaccines particularly if administered into the superficial layers of the subcutaneous tissue.

4.5 Interaction with other medicinal products and other forms of interaction

Based on the results of concomitant use clinical studies, ADACEL can be administered concomitantly with any of the following vaccines: inactivated Influenza vaccine, Hepatitis B vaccine, Inactivated or Oral Poliomyelitis vaccine and recombinant Human Papillomavirus vaccine (See section 4.8) according to local recommendations.

Separate limbs must be used for the site of injection of concomitant parenteral vaccines. Interaction studies have not been carried out with other vaccines, biological products, or therapeutic medications. However, in accordance with commonly accepted immunization guidelines, since ADACEL is an inactivated product it may be administered concomitantly with other vaccines or immunoglobulins at a separate injection site.

In the case of immunosuppressive therapy please refer to section 4.4.

4.6 Fertility, pregnancy and lactation

Pregnancy

Data on a limited number of exposed pregnancies indicated no adverse effect of ADACEL on pregnancy or on the health of the foetus/newborn child. To date, no other relevant epidemiological data are available. Animal studies do not indicate direct or indirect harmful effects with respect to pregnancy, embryonal/foetal development, parturition or postnatal development.

ADACEL should be given to a pregnant woman only if clearly needed, based on an assessment of the benefits versus the risks.

Breast-feeding

It is not known whether the active substances included in ADACEL are excreted in human milk but antibodies to the vaccine antigens have been found to be transferred to the suckling offspring of rabbits. An animal developmental study conducted in rabbits has not shown any harmful effects of maternal antibodies induced by the vaccine on offspring postnatal development.

However, the effect on breast-fed infants of the administration of ADACEL to their mothers has not been studied. The risks and benefits of vaccination should be assessed before making the decision to immunize a nursing woman.

Fertility

ADACEL has not been evaluated in fertility studies.

4.7 Effects on ability to drive and use machines

No studies on the effects on the ability to drive or use machines have been performed. ADACEL has no or negligible influence on ability to drive and use machines.

4.8 Undesirable effects

Summary of the safety profile

In clinical trials ADACEL was given to a total of 3,234 persons, including 298 children (4 to 6 years), 1,184 adolescents (11 to 17 years) and 1,752 adults (18 to 64 years). Most commonly reported reactions following vaccination included local reactions at the injection site (pain, redness and swelling) that occurred in 21% - 78% of the vaccinees, headache and tiredness that occurred in 16% - 44% of vaccinees. These signs and symptoms usually were mild in intensity and occurred within 48 hours following vaccination. They all resolved without sequelae.

Safety analysis was conducted in 1,042 healthy adolescent males and females aged 10 to 17 years during a clinical trial. They received quadrivalent human papillomavirus types 6/11/16/18 vaccine (Gardasil) concurrently with a dose of ADACEL and a dose of quadrivalent meningococcal conjugate vaccine serogroup A, C, Y and W135. The safety profiles were similar in both concomitant and non concomitant groups. Higher frequencies of swelling at the Gardasil injection site, bruising and pain at ADACEL injection sites were observed in the concomitant administration group. The differences observed between concomitant and non concomitant groups were less than 7% and in a majority of subjects the adverse events were reported as mild to moderate in intensity.

Tabulated list of adverse reactions

Adverse reactions are ranked under headings of frequency using the following convention:

Very common Common Uncommon Rare

Very rare

cannot be estimated from the available data

Table 1 presents adverse reactions observed in clinical trials and also includes additional adverse events which have been spontaneously reported during the postmarketing use of ADACEL worldwide. Because post-marketing adverse events are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to vaccine exposure. Therefore, the frequency category “Not known” is assigned to these adverse events.

verse Events

Description of selected adverse reactions

General Disorders and Administration Site Conditions:

Large injection site reactions (>50 mm), including extensive limb swelling from the injection site beyond one or both joints occur after administration of ADACEL in adolescents and adults. These reactions usually start within 24 - 72 hours after vaccination, may be associated with erythema, warmth, tenderness or pain at the injection site and resolve spontaneously within 3 - 5 days.

Paediatric population

The safety profile of ADACEL as presented in Table 1 includes data from a clinical trial in 298 children 4 to 6 years of age who had previously received a total of 4 doses, including primary immunization, with DTaP-IPV combined with Hib, at approximately 2, 4, 6 and 18 months of age. In this clinical study, the most common adverse events reported within 14 days post-vaccination were pain at the injection site (in 39.6 % of subjects) and tiredness (in 31.5 % of subjects).

*For children 4-6 years of age previously primed with DTaP (diphtheria toxoid [paediatric dose], tetanus and acellular pertussis) at 2, 4, 6 and 18 months of age, a booster response is defined as a 4-fold increase in concentration of anti-pertussis antibodies.

For adolescents and adults, a booster response is defined as a 2-fold increase in concentration of antipertussis antibodies in participants with high pre-vaccination concentration and a 4-fold increase in participants with low pre-vaccination concentration.

The safety and immunogenicity of ADACEL in adults and adolescents was shown to be comparable to that observed with a single dose of an adult formulation diphtheria-tetanus (Td) adsorbed vaccine containing the same amount of tetanus and diphtheria toxoids.

Serological correlates for protection against pertussis have not been established. On comparison with data from the Sweden I pertussis efficacy trials conducted between 1992 and 1996, where primary immunization with Sanofi Pasteur Limited’s acellular pertussis infant DTaP formulation confirmed a protective efficacy of 85% against pertussis disease, it is considered that ADACEL had elicited protective immune responses. The pertussis antibody levels for all antigens following a booster dose of ADACEL in adolescents and adults exceeded those observed in a household contact study nested within the efficacy trial.
