FULL PRESCRIBING INFORMATION

1 INDICATIONS AND USAGE

HIBERIX® is indicated for active immunization for the prevention of invasive disease caused by Haemophilus influenzae type b. HIBERIX is approved for use in children 6 weeks through 4 years of age (prior to fifth birthday).

The evaluation of effectiveness of HIBERIX was based on immune responses in children using serological endpoints that predict protection from invasive disease due to H. influenzae type b [see Clinical Pharmacology (12.1), Clinical Studies (14.1)]. These protective antibody levels have not been evaluated in clinical trials in which a booster dose of HIBERIX is compared to a booster dose of a US-licensed Haemophilus b Conjugate Vaccine in children who previously received a primary series with a US-licensed Haemophilus b Conjugate Vaccine [see Clinical Studies (14.1)].

2 DOSAGE AND ADMINISTRATION

2.1 Reconstitution

HIBERIX is to be reconstituted only with the accompanying saline diluent. The reconstituted vaccine should be a clear and colorless solution. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. If either of these conditions exists, the vaccine should not be administered.

Figure 1 Figure 2 Figure 3 Figure 4

Figure 1. Cleanse both vial stoppers. Withdraw 0.6 mL of saline diluent from accompanying vial.

Figure 2. Transfer 0.6 mL saline diluent into lyophilized vaccine vial.

Figure 3. Shake the vial well.

Figure 4. After reconstitution, withdraw 0.5 mL of reconstituted vaccine and administer intramuscularly.

Use a separate sterile needle and sterile syringe for each individual.

After reconstitution, administer HIBERIX immediately or store refrigerated between 2° and 8°C (36° and 46°F) and administer within 24 hours. If the vaccine is not administered immediately, shake the solution well again before administration.

2.2 Administration

For intramuscular use only.

HIBERIX is administered as a single dose (0.5 mL) by intramuscular injection into the anterolateral aspect of the thigh or deltoid.

Do not administer this product intravenously, intradermally, or subcutaneously.

2.3 Dose and Schedule

HIBERIX is administered as a 4-dose series (0.5-mL each dose) given by intramuscular injection. The series consists of a primary immunization course of 3 doses administered at 2, 4, and 6 months of age, followed by a booster dose administered at 15 through 18 months of age. The first dose may be given as early as 6 weeks of age.

3 DOSAGE FORMS AND STRENGTHS

HIBERIX is a solution for injection supplied as a single-dose vial of lyophilized vaccine to be reconstituted with the accompanying vial of saline diluent. A single dose, after reconstitution, is 0.5 mL.

4 CONTRAINDICATIONS

Severe allergic reaction (e.g., anaphylaxis) after a previous dose of any H. influenzae type b- or tetanus toxoid-containing vaccine or any component of the vaccine is a contraindication to administration of HIBERIX [see Description (11)].

5 WARNINGS AND PRECAUTIONS

5.1 Guillain-Barré Syndrome

If Guillain-Barré syndrome has occurred within 6 weeks of receipt of a prior vaccine containing tetanus toxoid, the decision to give any tetanus toxoid-containing vaccine, including HIBERIX, should be based on careful consideration of the potential benefits and possible risks.

5.2 Syncope

Syncope (fainting) can occur in association with administration of injectable vaccines, including HIBERIX. Syncope can be accompanied by transient neurological signs such as visual disturbance, paresthesia, and tonic-clonic limb movements. Procedures should be in place to avoid falling injury and to restore cerebral perfusion following syncope.

5.3 Apnea in Premature Infants

Apnea following intramuscular vaccination has been observed in some infants born prematurely. Decisions about when to administer an intramuscular vaccine, including HIBERIX, to infants born prematurely should be based on consideration of the individual infant’s medical status, and the potential benefits and possible risks of vaccination.

5.4 Preventing and Managing Allergic Vaccine Reactions

Prior to administration, the healthcare provider should review the patient's immunization history for possible vaccine hypersensitivity. Epinephrine and other appropriate agents used for the control of immediate allergic reactions must be immediately available should an acute anaphylactic reaction occur.

5.5 Altered Immunocompetence

Safety and effectiveness of HIBERIX in immunosuppressed children have not been evaluated. If HIBERIX is administered to immunosuppressed children, including children receiving immunosuppressive therapy, the expected immune response may not be obtained.

5.6 Interference with Laboratory Tests

Urine antigen detection may not have a diagnostic value in suspected disease due to H. influenzae type b within 1 to 2 weeks after receipt of a H. influenzae type b-containing vaccine, including HIBERIX [see Drug Interactions (7.1)].

5.7 Tetanus Immunization

Immunization with HIBERIX does not substitute for routine tetanus immunization.

6 ADVERSE REACTIONS

6.1 Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a vaccine cannot be directly compared with rates in the clinical trials of another vaccine, and may not reflect the rates observed in practice. There is the possibility that broad use of HIBERIX could reveal adverse reactions not observed in clinical trials.

Across clinical trials, common solicited adverse events (≥20%) were pain and redness at the injection site, irritability, drowsiness, fever, loss of appetite, fussiness, and restlessness.

Study 1: In a randomized, controlled clinical trial conducted in the US, children were vaccinated with HIBERIX (N = 2,963), a US-licensed monovalent Haemophilus b Conjugate Vaccine (Control PRP-T) (Sanofi Pasteur SA) (N = 520), or a US-licensed combined Diphtheria and Tetanus Toxoids and Acellular Pertussis Adsorbed, Inactivated Poliovirus and Haemophilus b Conjugate Vaccine (DTaP-IPV/Hib) (Sanofi Pasteur Ltd.) (N = 520) at 2, 4, and 6 months of age. HIBERIX and Control PRP-T (Sanofi Pasteur SA) were administered concomitantly with PEDIARIX® (DTaP-HBV-IPV) [Diphtheria and Tetanus Toxoids and Acellular Pertussis Adsorbed, Hepatitis B (Recombinant) and Inactivated Poliovirus Vaccine] and Pneumococcal 13-valent Conjugate Vaccine (PCV13) (Wyeth Pharmaceuticals Inc.) with Doses 1, 2, and 3 and ROTARIX® [Rotavirus Vaccine, Live, Oral] with Doses 1 and 2. DTaP-IPV/Hib was administered concomitantly with PCV13 and ENGERIX-B® [Hepatitis B Vaccine (Recombinant)] with Doses 1, 2, and 3 and ROTARIX with Doses 1 and 2. If a birth dose of hepatitis B vaccine was received, ENGERIX-B was given with Doses 1 and 3. In the total population, 51.2% were male; 61% were white, 8% were Asian, 9% were black, and 22% were other racial/ethnic groups.

In 7 additional clinical studies, 1,008 children received HIBERIX as a booster dose following primary vaccination with either HIBERIX (N = 530), Haemophilus b Conjugate Vaccine (Control PRP-T) (Sanofi Pasteur SA) (N = 235), Haemophilus b Conjugate Vaccine (Merck & Co., Inc.) (N = 26), or Haemophilus b Conjugate Vaccine (Wyeth Pharmaceuticals Inc.) (no longer licensed in the US, N = 217). None of the studies included a comparator group that received a booster dose with a US-licensed Haemophilus b Conjugate Vaccine. Studies were conducted in Europe, Canada, and Latin America. Across these studies, the mean age of subjects at the time of booster vaccination with HIBERIX ranged from 16 to 19 months. At the time of vaccination, 172 (17.1%) subjects were 11 to 14 months of age, 642 (63.7%) subjects were 15 to 18 months of age, and 194 (19.2%) subjects were 19 to 25 months of age. Approximately half of the subjects were male. Among subjects for whom information on race/ethnicity was available, nearly all subjects were white.

In these 7 studies, HIBERIX was administered concomitantly with non-US formulations (containing 2.5 mg 2-phenoxyethanol per dose as preservative) of one of the following US-licensed vaccines: INFANRIX® (DTaP) [Diphtheria and Tetanus Toxoids and Acellular Pertussis Vaccine Adsorbed], KINRIX® (DTaP-IPV) [Diphtheria and Tetanus Toxoids and Acellular Pertussis Adsorbed and Inactivated Poliovirus Vaccine], or PEDIARIX (DTaP-HBV-IPV). In the studies, DTaP-IPV and DTaP-HBV-IPV were administered in dosing regimens not approved in the US. Some subjects received DTaP-HBV (GlaxoSmithKline Biologicals, not licensed in US) concomitantly with HIBERIX.

Serious Adverse Events

In Study 1, one of 2,963 subjects who received HIBERIX and coadministered vaccines given at 2, 4, and 6 months of age experienced a SAE which was in temporal association with vaccination and had no alternative plausible causes (convulsion on Day 14 after Dose 1).

In the 7 additional studies, two of 1,008 subjects reported a serious adverse event that occurred in the 31-day period following booster immunization with HIBERIX. One subject developed bilateral pneumonia 9 days post-vaccination and one subject experienced asthenia following accidental drug ingestion 18 days post-vaccination.

6.2 Postmarketing Experience

In addition to reports in clinical trials, worldwide voluntary reports of adverse events received for HIBERIX since market introduction (1996) of this vaccine are listed below. This list includes serious events and/or events which have a plausible causal connection to HIBERIX. Because these events are reported voluntarily from a population of uncertain size, it is not possible to reliably estimate their frequency or establish a causal relationship to vaccination.

General Disorders and Administration Site Conditions

Extensive swelling of the vaccinated limb, injection site induration.

Immune System Disorders

Allergic reactions (including anaphylactic and anaphylactoid reactions), angioedema.

Nervous System Disorders

Convulsions (with or without fever), hypotonic-hyporesponsive episode (i.e., sudden onset of hypotonia, hyporesponsiveness, and pallor or cyanosis), somnolence, syncope, or vasovagal responses to injection.

Respiratory, Thoracic, and Mediastinal Disorders

Apnea [see Warnings and Precautions (5.3)].

Skin and Subcutaneous Tissue Disorders

Rash, urticaria.

7 DRUG INTERACTIONS

7.1 Interference with Laboratory Tests

Haemophilus b capsular polysaccharide derived from Haemophilus b Conjugate Vaccines has been detected in the urine of some vaccinees.1 Urine antigen detection may not have a diagnostic value in suspected disease due to H. influenzae type b within 1 to 2 weeks after receipt of a H. influenzae type b-containing vaccine, including HIBERIX [see Warnings and Precautions (5.6)].

7.2 Concomitant Vaccine Administration

In Study 1, HIBERIX was administered concomitantly with PEDIARIX (DTaP-HBV-IPV), PCV13, and ROTARIX [see Adverse Reactions (6.1), Clinical Studies (14.2)].

In the 7 additional studies, a booster dose of HIBERIX was administered concomitantly with 1 of the following vaccines: DTaP, DTaP-IPV, DTaP-HBV-IPV, or DTaP-HBV (GlaxoSmithKline Biologicals, not licensed in the US). The formulations of DTaP, DTaP-IPV, and DTaP-HBV-IPV were non-US formulations (containing 2.5 mg 2-phenoxyethanol per dose as preservative) of the following US-licensed vaccines: INFANRIX, KINRIX, and PEDIARIX, respectively. In these studies, DTaP-IPV and DTaP-HBV-IPV were administered in dosing regimens that are not approved in the US. [See Adverse Reactions (6.1), Clinical Studies (14.1).]

If HIBERIX is administered concomitantly with other injectable vaccines, they should be given with separate syringes and at different injection sites. HIBERIX should not be mixed with any other vaccine in the same syringe or vial.

7.3 Immunosuppressive Therapies

Immunosuppressive therapies, including irradiation, antimetabolites, alkylating agents, cytotoxic drugs, and corticosteroids (used in greater than physiologic doses), may reduce the immune response to HIBERIX.

8 USE IN SPECIFIC POPULATIONS

8.1 Pregnancy

Pregnancy Category C

Animal reproduction studies have not been conducted with HIBERIX. It is also not known whether HIBERIX can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity.

8.4 Pediatric Use

Safety and effectiveness of HIBERIX in children younger than 6 weeks of age and in children 5 to 16 years of age have not been established.

11 DESCRIPTION

HIBERIX [Haemophilus b Conjugate Vaccine (Tetanus Toxoid Conjugate)] is a solution for intramuscular injection, supplied as a sterile, lyophilized powder which is reconstituted at the time of use with the accompanying saline diluent. HIBERIX contains Haemophilus b capsular polysaccharide (polyribosyl-ribitol-phosphate [PRP]), a high molecular weight polymer prepared from the Haemophilus influenzae type b strain 20,752 grown in a synthetic medium that undergoes heat inactivation and purification. The tetanus toxin, prepared from Clostridium tetani grown in a semi-synthetic medium, is detoxified with formaldehyde and purified. The capsular polysaccharide is covalently bound to the tetanus toxoid. After purification, the conjugate is lyophilized in the presence of lactose as a stabilizer. The diluent for HIBERIX is a sterile saline solution (0.9% sodium chloride) supplied in vials.

After reconstitution, each 0.5-mL dose is formulated to contain 10 mcg of purified capsular polysaccharide conjugated to approximately 25 mcg of tetanus toxoid, 12.6 mg of lactose, and ≤0.5 mcg of residual formaldehyde.

HIBERIX does not contain a preservative.

The lyophilized vaccine and saline diluent vial stoppers are not made with natural rubber latex.

12 CLINICAL PHARMACOLOGY

12.1 Mechanism of Action

Haemophilus influenzae is a gram-negative coccobacillus. Most strains of H. influenzae that cause invasive disease are type b. H. influenzae type b can cause invasive disease such as sepsis and meningitis.

Specific levels of antibodies to polyribosyl-ribitol-phosphate (anti-PRP) have been shown to correlate with protection against invasive disease due to H. influenzae type b. Based on data from passive antibody studies2 and a clinical efficacy study with unconjugated Haemophilus b polysaccharide vaccine3, an anti-PRP concentration of 0.15 mcg/mL has been accepted as a minimal protective level. Data from an efficacy study with unconjugated Haemophilus b polysaccharide vaccine indicate that an anti-PRP concentration of ≥1.0 mcg/mL predicts protection through at least a 1-year period.4,5 These antibody levels have been used to evaluate the effectiveness of Haemophilus b Conjugate Vaccines, including HIBERIX.

13 NONCLINICAL TOXICOLOGY

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

HIBERIX has not been evaluated for carcinogenic or mutagenic potential, or for impairment of fertility.

14 CLINICAL STUDIES

14.1 Immunological Evaluation

Primary Series Vaccination (Doses 1, 2, and 3)

The immunogenicity of HIBERIX was evaluated in a randomized, controlled trial (Study 1). HIBERIX or control vaccines were administered concomitantly with US-licensed vaccines [see Adverse Reactions (6.1)].

Anti-PRP GMCs and seroprotection rates 1 month following Dose 3 of HIBERIX, Control PRP-T (Sanofi Pasteur SA), or DTaP-IPV/Hib are presented in Table 3.

In 6 clinical studies, the immune response to HIBERIX administered as a booster dose was evaluated in a total of 415 children 12 to 23 months of age. At the time of vaccination, 30 children were 12 to 14 months of age, 316 children were 15 to 18 months of age, and 69 children were 19 to 23 months of age. Among subjects, 43% to 60% were male. Among subjects for whom information on race/ethnicity was available, nearly all subjects were white. None of the studies included a comparator group that received a booster dose with a US-licensed Haemophilus b Conjugate Vaccine. Characteristics of 3 of these studies are presented in Table 4.

a Canadian study in children 16 to 18 months of age who previously received 3 doses of DTaP-HBV-IPV and Haemophilus b Conjugate Vaccine (Control PRP-T) (Sanofi Pasteur SA). The booster dose of HIBERIX was coadministered with DTaP-HBV-IPV (a fourth consecutive dose of PEDIARIX is not approved in the US). In this study, pre-vaccination sera may have been obtained up to 1 week prior to booster vaccination with HIBERIX.
 
b Canadian study in children 16 to 19 months of age who previously received 3 doses of DTaP-IPV and HIBERIX. The booster dose of HIBERIX was coadministered with DTaP-IPV. The DTaP-IPV dosing regimen is not approved in the US.
 
c German study in children 16 to 23 months of age who previously received 3 doses of DTaP-HBV (GlaxoSmithKline Biologicals, not licensed in the US) and HIBERIX. The booster dose of HIBERIX was coadministered with DTaP-HBV.

14.2 Concomitant Vaccine Administration

Primary Series Vaccination (Doses 1, 2, and 3)

In US Study 1, subjects who received HIBERIX concomitantly with PEDIARIX (DTaP-HBV-IPV) and PCV13 at 2, 4, and 6 months of age had no evidence for reduced antibody responses relative to the response in control subjects administered Control PRP-T (Sanofi Pasteur SA) concomitantly with PEDIARIX (DTaP-HBV-IPV) and PCV13, to pertussis antigens (GMC to pertussis toxin, filamentous hemagglutinin, and pertactin), diphtheria toxoid (antibody levels ≥0.1 IU/mL), tetanus toxoid (antibody levels ≥0.1 IU/mL), poliovirus types 1, 2, and 3 (antibody levels ≥1:8 to each virus), PCV13 (antibody levels ≥0.2 mcg/mL and GMC to each serotype), or hepatitis B (anti-hepatitis B surface antigen ≥10 mIU/mL). The immune responses to PEDIARIX (DTaP-HBV-IPV) and PCV13 were evaluated 1 month following Dose 3. Subjects in both groups received ROTARIX at 2 and 4 months of age.

Booster Vaccination (Dose 4)

In 7 additional studies, a booster dose of HIBERIX was administered concomitantly with non-US formulations of INFANRIX, KINRIX, and PEDIARIX. Non-US formulations of KINRIX and PEDIARIX were administered in dosing regimens not approved in the US.

Sufficient data are not available to confirm lack of interference in immune responses to vaccines administered concomitantly with a booster dose of HIBERIX.
