    Dosage and Administration (2.2, 2.3)

    09/2020

    INDICATIONS AND USAGE

    BOOSTRIX is a vaccine indicated for active booster immunization against tetanus, diphtheria, and pertussis in individuals aged 10 years and older. (1)

    DOSAGE AND ADMINISTRATION

    For intramuscular use only.

    Each dose of BOOSTRIX is administered as a 0.5-mL injection. (2.2)
    An initial dose of BOOSTRIX is administered 5 years or more after the last dose of the Diphtheria and Tetanus Toxoids and Acellular Pertussis (DTaP) series or 5 years or more after a dose of Tetanus and Diphtheria Toxoids Adsorbed (Td). BOOSTRIX may be administered as an additional dose 9 years or more after the initial dose of Tetanus Toxoid, Reduced Diphtheria Toxoid and Acellular Pertussis Vaccine Adsorbed (Tdap). (2.2)
    BOOSTRIX may be administered for tetanus prophylaxis for wound management. For management of a tetanus-prone wound, a dose of BOOSTRIX may be administered if at least 5 years have elapsed since previous receipt of a tetanus toxoid-containing vaccine. (2.2)

    DOSAGE FORMS AND STRENGTHS

    Single-dose vials and single-dose prefilled syringes containing a 0.5-mL suspension for injection. (3)

    CONTRAINDICATIONS

    Severe allergic reaction (e.g., anaphylaxis) after a previous dose of any tetanus toxoid-, diphtheria toxoid-, or pertussis antigen-containing vaccine or to any component of BOOSTRIX. (4.1)
    Encephalopathy (e.g., coma, decreased level of consciousness, prolonged seizures) within 7 days of administration of a previous pertussis antigen-containing vaccine. (4.2)

    WARNINGS AND PRECAUTIONS

    The tip caps of the prefilled syringes contain natural rubber latex which may cause allergic reactions. (5.2)
    If Guillain-Barré syndrome occurred within 6 weeks of receipt of a prior vaccine containing tetanus toxoid, the risk of Guillain-Barré syndrome may be increased following a subsequent dose of tetanus toxoid-containing vaccine, including BOOSTRIX. (5.3)
    Progressive or unstable neurologic conditions are reasons to defer vaccination with a pertussis-containing vaccine, including BOOSTRIX. (5.4)
    Persons who experienced an Arthus-type hypersensitivity reaction following a prior dose of a tetanus toxoid-containing vaccine should not receive BOOSTRIX unless at least 10 years have elapsed since the last dose of a tetanus toxoid-containing vaccine. (5.5)
    Syncope (fainting) can occur in association with administration of injectable vaccines, including BOOSTRIX. Procedures should be in place to avoid falling injury and to restore cerebral perfusion following syncope. (5.7)

    ADVERSE REACTIONS

     
    Following an initial vaccination with BOOSTRIX:
    Common solicited adverse reactions (≥15%) in adolescents (aged 10 to 18 years) were pain, redness, and swelling at the injection site; increase in arm circumference of the injected arm; headache; fatigue; and gastrointestinal symptoms. (6.1)
    Common solicited adverse reactions (≥15%) in adults (aged 19 to 64 years) were pain, redness, and swelling at the injection site; headache; fatigue; and gastrointestinal symptoms. (6.1)
    The most common solicited adverse reaction (≥15%) in the elderly (aged 65 years and older) was pain at the injection site. (6.1)

    Following revaccination with BOOSTRIX:

    Common solicited adverse reactions (≥15%) in adults (aged 20 years and older) were pain, redness, and swelling at the injection site; headache; and fatigue. (6.1)

    To report SUSPECTED ADVERSE REACTIONS, contact GlaxoSmithKline at 1-888-825-5249 or VAERS at 1-800-822-7967 or www.vaers.hhs.gov.

    DRUG INTERACTIONS

    In subjects aged 11 to 18 years, lower levels for antibodies to pertactin (PRN) were observed when BOOSTRIX was administered concomitantly with meningococcal conjugate vaccine (serogroups A, C, Y, and W-135) as compared with BOOSTRIX administered first. (7.1)
    In subjects aged 19 to 64 years, lower levels for antibodies to filamentous hemagglutinin (FHA) and PRN were observed when BOOSTRIX was administered concomitantly with an inactivated influenza vaccine as compared with BOOSTRIX alone. (7.1)
    Do not mix BOOSTRIX with any other vaccine in the same syringe or vial. (7.1)

    See 17 for PATIENT COUNSELING INFORMATION.

    Revised: 9/2020

  • Table of Contents
  • 1 INDICATIONS AND USAGE

    BOOSTRIX is indicated for active booster immunization against tetanus, diphtheria, and pertussis in individuals aged 10 years and older.

  • 2 DOSAGE AND ADMINISTRATION

    For intramuscular use only.

    2.1 Preparation for Administration

    Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. Do not use the vaccine if either of these conditions exist. Shake vigorously to obtain a homogeneous, turbid, white suspension before administration. Do not use if resuspension does not occur with vigorous shaking.

    For the prefilled syringes, attach a sterile needle and administer intramuscularly.

    For the vials, use a sterile needle and sterile syringe to withdraw the 0.5-mL dose and administer intramuscularly. Changing needles between drawing vaccine from a vial and injecting it into a recipient is not necessary unless the needle has been damaged or contaminated.

    2.2 Administration, Dose, and Schedule

    BOOSTRIX is administered as a 0.5-mL intramuscular injection into the deltoid muscle of the upper arm.

    An initial dose of BOOSTRIX is administered 5 years or more after the last dose of the Diphtheria and Tetanus Toxoids and Acellular Pertussis (DTaP) series or 5 years or more after a dose of Tetanus and Diphtheria Toxoids Adsorbed (Td).

    BOOSTRIX may be administered as an additional dose 9 years or more after the initial dose of Tetanus Toxoid, Reduced Diphtheria Toxoid and Acellular Pertussis Vaccine Adsorbed (Tdap).

    BOOSTRIX may be administered for tetanus prophylaxis for wound management. For management of a tetanus-prone wound, a dose of BOOSTRIX may be administered if at least 5 years have elapsed since previous receipt of a tetanus toxoid-containing vaccine.

    2.3 Additional Dosing Information

    The use of BOOSTRIX as a primary series or to complete the primary series for diphtheria, tetanus, or pertussis has not been established.

  • 3 DOSAGE FORMS AND STRENGTHS

    BOOSTRIX is a suspension for injection available in 0.5-mL single-dose vials and prefilled TIP-LOK syringes.

  • 4 CONTRAINDICATIONS

    4.1 Hypersensitivity

    A severe allergic reaction (e.g., anaphylaxis) after a previous dose of any tetanus toxoid-, diphtheria toxoid-, or pertussis antigen-containing vaccine or any component of this vaccine is a contraindication to administration of BOOSTRIX [see Description (11)]. Because of the uncertainty as to which component of the vaccine might be responsible, none of the components should be administered. Alternatively, such individuals may be referred to an allergist for evaluation if immunization with any of these components is considered.

    4.2 Encephalopathy

    Encephalopathy (e.g., coma, decreased level of consciousness, prolonged seizures) within 7 days of administration of a previous dose of a pertussis antigen-containing vaccine that is not attributable to another identifiable cause is a contraindication to administration of any pertussis antigen-containing vaccine, including BOOSTRIX.

  • 5 WARNINGS AND PRECAUTIONS

    5.1 Management of Acute Allergic Reactions

    Epinephrine and other appropriate agents used for the control of immediate allergic reactions must be immediately available should an acute hypersensitivity or anaphylactic reaction occur following the administration of BOOSTRIX.

    5.2 Latex

    The tip caps of the prefilled syringes contain natural rubber latex which may cause allergic reactions.

    5.3 Guillain-Barré Syndrome and Brachial Neuritis

    If Guillain-Barré syndrome occurred within 6 weeks of receipt of a prior vaccine containing tetanus toxoid, the risk of Guillain-Barré syndrome may be increased following a subsequent dose of tetanus toxoid-containing vaccine, including BOOSTRIX. A review by the Institute of Medicine (IOM) found evidence for a causal relationship between receipt of tetanus toxoid and both Guillain-Barré syndrome and brachial neuritis.1

    5.4 Progressive or Unstable Neurologic Disorders

    Progressive or unstable neurologic conditions (e.g., cerebrovascular events, acute encephalopathic conditions) are reasons to defer vaccination with a pertussis-containing vaccine, including BOOSTRIX. It is not known whether administration of BOOSTRIX to persons with an unstable or progressive neurologic disorder might hasten manifestations of the disorder or affect the prognosis. Administration of BOOSTRIX to persons with an unstable or progressive neurologic disorder may result in diagnostic confusion between manifestations of the underlying illness and possible adverse effects of vaccination.

    5.5 Arthus-Type Hypersensitivity

    Persons who experienced an Arthus-type hypersensitivity reaction following a prior dose of a tetanus toxoid-containing vaccine usually have a high serum tetanus antitoxin level and should not receive BOOSTRIX or other tetanus toxoid-containing vaccines unless at least 10 years have elapsed since the last dose of tetanus toxoid-containing vaccine.

    5.6 Altered Immunocompetence

    As with any vaccine, if administered to immunosuppressed persons, including individuals receiving immunosuppressive therapy, the expected immune response may not be obtained.

    5.7 Syncope

    Syncope (fainting) can occur in association with administration of injectable vaccines, including BOOSTRIX. 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.

  • 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.

    Table 1 provides an overview of the studies that evaluated the safety of BOOSTRIX in various populations.

    In these studies, subjects were monitored for solicited adverse events using standardized diary cards during the 4 days (Days 0 to 3) or 15 days (Days 0 to 14) following vaccination. Unsolicited adverse events were monitored for the 31-day period following vaccination (Days 0 to 30).

    Serious adverse events were monitored for 6 months post-vaccination in the initial-dose studies (NCT00109330, NCT00263679, NCT00346073, NCT00835237) and for the 31-day (Days 0 to 30) period post-vaccination in the revaccination (NCT01738477, NCT00489970) and the concomitant-vaccine administration studies (NCT00282295, NCT00385255).

    Initial-Dose Studies

    In clinical studies, 4,949 adolescents (aged 10 to 18 years) and 4,076 adults (aged 19 years and older) were vaccinated with a single dose of BOOSTRIX. Of these adolescents, 1,341 were vaccinated with BOOSTRIX in a coadministration study with meningococcal conjugate vaccine [see Drug Interactions (7.1), Clinical Studies (14.4)]. Of these adults, 1,104 were aged 65 years and older [see Clinical Studies (14.2)]. A total of 860 adults aged 19 years and older received concomitant vaccination with BOOSTRIX and influenza vaccines in a coadministration study [see Drug Interactions (7.1), Clinical Studies (14.5)].

    Solicited Adverse Events in the U.S. Adolescent Study: Table 2 presents the solicited local adverse reactions and general adverse events within 15 days of vaccination with BOOSTRIX or Td vaccine for the total vaccinated cohort.

    The primary safety endpoint was the incidence of Grade 3 pain (spontaneously painful and/or prevented normal activity) at the injection site within 15 days of vaccination. Grade 3 pain was reported in 4.6% of those who received BOOSTRIX compared with 4.0% of those who received the Td vaccine. The difference in rate of Grade 3 pain was within the pre-defined clinical limit for non-inferiority (upper limit of the 95% CI for the difference [BOOSTRIX minus Td] ≤4%).

    Unsolicited Adverse Events in the U.S. Adolescent Study: The incidence of unsolicited adverse events reported in the 31 days after vaccination was comparable between the 2 groups (25.4% and 24.5% for BOOSTRIX and Td vaccine, respectively).

    Solicited Adverse Events in the German Adolescent Study: BOOSTRIX was administered to 319 children aged 10 to 12 years previously vaccinated with 5 doses of acellular pertussis antigen-containing vaccines; 193 of these subjects received 5 doses of INFANRIX (Diphtheria and Tetanus Toxoids and Acellular Pertussis Vaccine Adsorbed). Table 3 presents the rates of solicited local adverse reactions and fever within 15 days of vaccination for those subjects who had previously been vaccinated with 5 doses of INFANRIX. No cases of whole arm swelling were reported. Two individuals (2/193) reported large injection site swelling (range: 110 to 200 mm diameter), in 1 case associated with Grade 3 pain. Neither individual sought medical attention. These episodes were reported to resolve without sequelae within 5 days.

    Serious Adverse Events (SAEs): In the U.S. and German adolescent safety studies, no serious adverse events were reported to occur within 31 days of vaccination. During the 6-month extended safety evaluation period, no serious adverse events that were of potential autoimmune origin or new onset and chronic in nature were reported to occur. In non-U.S. adolescent studies in which serious adverse events were monitored for up to 37 days, 1 subject was diagnosed with insulin-dependent diabetes 20 days following administration of BOOSTRIX. No other serious adverse events of potential autoimmune origin or that were new onset and chronic in nature were reported to occur in these studies. In the U.S. adult (aged 19 to 64 years) study, serious adverse events were reported to occur during the entire study period (0-6 months) by 1.4% and 1.7% of subjects who received BOOSTRIX and the comparator Tdap vaccine, respectively. During the 6-month extended safety evaluation period, no serious adverse events of a neuroinflammatory nature or with information suggesting an autoimmune etiology were reported in subjects who received BOOSTRIX. In the U.S. elderly (aged 65 years and older) study, serious adverse events were reported to occur by 0.7% and 0.9% of subjects who received BOOSTRIX and the comparator Td vaccine, respectively, during the 31-day period after vaccination. Serious adverse events were reported to occur by 4.2% and 2.2% of subjects who received BOOSTRIX and the comparator Td vaccine, respectively, during the 6-month period after vaccination.

    Revaccination Studies

    U.S. Revaccination Studies in Adults: In 2 clinical studies, 974 adults (aged 20 years and older) were vaccinated with a dose of BOOSTRIX [see Clinical Studies (14.3)].

  • 7 DRUG INTERACTIONS

    7.1 Concomitant Vaccine Administration

    BOOSTRIX was administered concomitantly with MENACTRA in a clinical study of subjects aged 11 to 18 years [see Clinical Studies (14.4)]. Post-vaccination geometric mean antibody concentrations (GMCs) to pertactin (PRN) were lower following BOOSTRIX administered concomitantly with meningococcal conjugate vaccine compared with BOOSTRIX administered first. It is not known if the efficacy of BOOSTRIX is affected by the reduced response to PRN.

    BOOSTRIX was administered concomitantly with FLUARIX (Influenza Virus Vaccine) in a clinical study of subjects aged 19 to 64 years [see Clinical Studies (14.5)]. Lower GMCs for antibodies to the pertussis antigens filamentous hemagglutinin (FHA) and PRN were observed when BOOSTRIX was administered concomitantly with FLUARIX as compared with BOOSTRIX alone. It is not known if the efficacy of BOOSTRIX is affected by the reduced response to FHA and PRN.

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

    7.2 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 BOOSTRIX.

  • 8 USE IN SPECIFIC POPULATIONS

    8.1 Pregnancy

    Pregnancy Exposure Registry

    There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to BOOSTRIX during pregnancy. Healthcare providers are encouraged to register women by calling 1-888-452-9622.

    Risk Summary

    All pregnancies have a risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. There are no adequate and well-controlled studies of BOOSTRIX in pregnant women in the U.S.

    Available data suggest that the rates of major birth defects and miscarriage in women who received BOOSTRIX within 28 days prior to conception or during pregnancy are consistent with estimated background rates (see Data).

    A developmental toxicity study was performed in female rats administered INFANRIX prior to mating and BOOSTRIX during gestation, 0.1 mL at each occasion (a single human dose is 0.5 mL). In a second study, female rats were administered 0.2 mL of BOOSTRIX prior to mating and during the gestation and lactation period. In a third study, female New Zealand White rabbits were given 0.5 mL (full human dose) of BOOSTRIX (non-U.S. formulation) prior to mating and during gestation. These studies revealed no evidence of harm to the fetus due to BOOSTRIX (see Data).

    Data

    Human Data: An assessment of data from the U.S. pregnancy registry over approximately 14 years (2005-2019) included 1,455 prospective reports of exposure to BOOSTRIX within 28 days prior to conception or during pregnancy. Of these reports, 250 had known pregnancy outcomes available. After excluding those with exposure in the third trimester (n = 193) and those with an unknown exposure timing (n = 10), there were 47 pregnancies with known outcomes with exposure within 28 days prior to conception through the second trimester. Outcomes among these prospectively followed pregnancies included 3 cases of miscarriage in women exposed in the first trimester and no major birth defects in infants born to women with exposure within 28 days prior to conception or during pregnancy.

    An assessment of spontaneous and postmarketing data through August 2019 included 749 prospective reports of exposure to non-U.S. formulations of BOOSTRIX/Tdap or BOOSTRIX-Polio/Tdap-IPV within 28 days prior to conception or during pregnancy. Of these reports, 163 had known pregnancy outcomes available. After excluding elective terminations (n = 3), those with exposure in the third trimester (n = 61), and those with an unknown exposure timing (n = 6), there were 93 pregnancies with known outcomes with exposure during the 28 days prior to conception through the second trimester. Outcomes among these prospectively followed pregnancies included 1 live infant with a major birth defect born to a woman with exposure during the first trimester, 1 stillbirth in a woman exposed in the first trimester, and 4 cases of miscarriage in women exposed in the first trimester.

    Animal Data: Developmental toxicity studies were performed in female rats and New Zealand White rabbits. In one study, female rats were administered 0.1 mL of INFANRIX (a single human dose is 0.5 mL) by intramuscular injection 30 days prior to mating and 0.1 mL of BOOSTRIX (a single human dose is 0.5 mL) by intramuscular injection on Gestation Days 6, 8, 11, and 15. The antigens in INFANRIX are the same as those in BOOSTRIX, but INFANRIX is formulated with higher quantities of these antigens. In a second study, female rats were administered 0.2 mL of BOOSTRIX by intramuscular injection 28 days and 14 days prior to mating, on Gestation Days 3, 8, 11, and 15, and on Lactation Day 7. In these studies, no adverse effects on embryo-fetal or pre-weaning development up to Postnatal Day 25 were observed; there were no fetal malformations or variations observed. In a third study, female New Zealand White rabbits were administered 0.5 mL (full human dose) of BOOSTRIX (non-U.S. formulation) by intramuscular injection on Premating Days -28 and -14 and on Gestation Days 3, 8, 11, 15, and 24. In this study, no adverse effects on embryo-fetal development related to BOOSTRIX were observed; postnatal development was not evaluated.

    8.2 Lactation

    Risk Summary

    It is not known whether the vaccine components of BOOSTRIX are excreted in human milk. Data are not available to assess the effect of administration of BOOSTRIX on breastfed infants or on milk production/excretion. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for BOOSTRIX and any potential adverse effects on the breastfed child from BOOSTRIX or from the underlying maternal condition. For preventive vaccines, the underlying maternal condition is susceptibility to disease prevented by the vaccine.

    8.4 Pediatric Use

    BOOSTRIX is not indicated for use in children aged younger than 10 years. Safety and effectiveness of BOOSTRIX in this age group have not been established.

    8.5 Geriatric Use

    In the initial-dose clinical trials, 1,104 subjects aged 65 years and older received BOOSTRIX; of these subjects, 299 were aged 75 years and older. Adverse events following BOOSTRIX were similar in frequency to those reported with the comparator Td vaccine [see Adverse Reactions (6.1)].

    A revaccination study of BOOSTRIX in adults aged 28 to 73 years [see Clinical Studies (14.3)] did not include sufficient numbers of subjects aged 65 and older to determine whether they respond differently from younger subjects.

  • 11 DESCRIPTION

    BOOSTRIX (Tetanus Toxoid, Reduced Diphtheria Toxoid and Acellular Pertussis Vaccine, Adsorbed) is a noninfectious, sterile, vaccine for intramuscular administration. It contains tetanus toxoid, diphtheria toxoid, and pertussis antigens (inactivated pertussis toxin [PT] and formaldehyde-treated FHA and PRN). The antigens are the same as those in INFANRIX, but BOOSTRIX is formulated with reduced quantities of these antigens.

    Tetanus toxin is produced by growing Clostridium tetani (C. tetani) in a modified Latham medium derived from bovine casein. The diphtheria toxin is produced by growing Corynebacterium diphtheriae (C. diphtheriae) in Fenton medium containing a bovine extract. The bovine materials used in these extracts are sourced from countries which the United States Department of Agriculture (USDA) has determined neither have nor are at risk of bovine spongiform encephalopathy (BSE). Both toxins are detoxified with formaldehyde, concentrated by ultrafiltration, and purified by precipitation, dialysis, and sterile filtration.

    The acellular pertussis antigens (PT, FHA, and PRN) are isolated from Bordetella pertussis (B. pertussis) culture grown in modified Stainer-Scholte liquid medium. PT and FHA are isolated from the fermentation broth; PRN is extracted from the cells by heat treatment and flocculation. The antigens are purified in successive chromatographic and precipitation steps. PT is detoxified using glutaraldehyde and formaldehyde. FHA and PRN are treated with formaldehyde.

    Each antigen is individually adsorbed onto aluminum hydroxide. Each 0.5-mL dose is formulated to contain 5 Lf of tetanus toxoid, 2.5 Lf of diphtheria toxoid, 8 mcg of inactivated PT, 8 mcg of FHA, and 2.5 mcg of PRN (69 kiloDalton outer membrane protein).

    Tetanus and diphtheria toxoid potency is determined by measuring the amount of neutralizing antitoxin in previously immunized guinea pigs. The potency of the acellular pertussis components (inactivated PT and formaldehyde-treated FHA and PRN) is determined by enzyme-linked immunosorbent assay (ELISA) on sera from previously immunized mice.

    Each 0.5-mL dose contains aluminum hydroxide as adjuvant (not more than 0.39 mg aluminum by assay), 4.4 mg of sodium chloride, ≤100 mcg of residual formaldehyde, and ≤100 mcg of polysorbate 80 (Tween 80).

    BOOSTRIX is available in vials and prefilled syringes. The tip caps of the prefilled syringes contain natural rubber latex; the plungers are not made with natural rubber latex. The vial stoppers are not made with natural rubber latex.

    BOOSTRIX is formulated without preservatives.

  • 12 CLINICAL PHARMACOLOGY

    12.1 Mechanism of Action

    Tetanus

    Tetanus is a condition manifested primarily by neuromuscular dysfunction caused by a potent exotoxin released by C. tetani. Protection against disease is due to the development of neutralizing antibodies to the tetanus toxin. A serum tetanus antitoxin level of at least 0.01 IU/mL, measured by neutralization assays, is considered the minimum protective level.2 A level ≥0.1 IU/mL by ELISA has been considered as protective.

    Diphtheria

    Diphtheria is an acute toxin-mediated infectious disease caused by toxigenic strains of C. diphtheriae. Protection against disease is due to the development of neutralizing antibodies to the diphtheria toxin. A serum diphtheria antitoxin level of 0.01 IU/mL, measured by neutralization assays, is the lowest level giving some degree of protection; a level of 0.1 IU/mL by ELISA is regarded as protective.3 Diphtheria antitoxin levels ≥1.0 IU/mL by ELISA have been associated with long-term protection.3

    Pertussis

    Pertussis (whooping cough) is a disease of the respiratory tract caused by B. pertussis. The role of the different components produced by B. pertussis in either the pathogenesis of, or the immunity to, pertussis is not well understood.

  • 13 NONCLINICAL TOXICOLOGY

    13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

    BOOSTRIX has not been evaluated for carcinogenic or mutagenic potential, or for impairment of male fertility in animals. Vaccination of female rabbits and rats with BOOSTRIX had no effect on fertility. [See Use in Specific Populations (8.1).]

  • 14 CLINICAL STUDIES

    14.1 Effectiveness of BOOSTRIX, INFANRIX, and PEDIARIX

    Effectiveness of BOOSTRIX

    The effectiveness of the tetanus and diphtheria toxoid components of BOOSTRIX is based on the immunogenicity of the individual antigens compared with U.S.-licensed vaccines using established serologic correlates of protection. The effectiveness of the pertussis components of BOOSTRIX was evaluated by comparison of the immune response of adolescents and adults following an initial dose of BOOSTRIX to the immune response of infants following a 3-dose primary series of INFANRIX or by comparison of the immune response of adults following an additional dose of BOOSTRIX to the immune response of infants following a 3-dose primary series of PEDIARIX. In addition, the ability of BOOSTRIX to induce a booster response to each of the antigens was evaluated.

    Efficacy of INFANRIX Against Pertussis

    The efficacy of a 3-dose primary series of INFANRIX in infants has been assessed in 2 clinical studies: A prospective efficacy trial conducted in Germany employing a household contact study design and a double-blind, randomized, active Diphtheria and Tetanus Toxoids (DT)-controlled trial conducted in Italy sponsored by the National Institutes of Health (NIH) (for details see INFANRIX prescribing information). In the household contact study, the protective efficacy of INFANRIX in infants against WHO-defined pertussis (21 days or more of paroxysmal cough with infection confirmed by culture and/or serologic testing) was calculated to be 89% (95% CI: 77%, 95%). When the definition of pertussis was expanded to include clinically milder disease, with infection confirmed by culture and/or serologic testing, the efficacy of INFANRIX against ≥7 days of any cough was 67% (95% CI: 52%, 78%) and against ≥7 days of paroxysmal cough was 81% (95% CI: 68%, 89%) (for details see INFANRIX prescribing information).

    Immune Responses to Pertussis Antigens of PEDIARIX Compared with INFANRIX

    The diphtheria, tetanus, and pertussis components in PEDIARIX are the same as those in INFANRIX. The effectiveness of the pertussis component of PEDIARIX was determined in clinical trials by comparison to antibody responses to INFANRIX (for details see PEDIARIX prescribing information).

    Immune Responses to Pertussis Antigens of BOOSTRIX Compared with INFANRIX or PEDIARIX

    Although a serologic correlate of protection for pertussis has not been established, serological data from a subset of infants immunized with a 3-dose primary series of INFANRIX in the German household contact study were compared with the sera of adolescents and adults immunized with an initial dose of BOOSTRIX [see Clinical Studies (14.2)]. Serological data from infants immunized with a 3-dose primary series of PEDIARIX in an additional pediatric study were compared with the sera of adults immunized with an additional dose of BOOSTRIX [see Clinical Studies (14.3)]. The GMCs to each of the pertussis antigens 1 month following a dose of BOOSTRIX were compared with the GMCs of infants following INFANRIX administered at 3, 4, and 5 months of age or were compared with the GMCs of infants following PEDIARIX administered at 2, 4, and 6 months of age. The majority of subjects in the study of INFANRIX had only anti-PT serology data.

    14.2 Immunological Evaluation following an Initial Dose of BOOSTRIX

    Adolescents (Aged 10 to 18 years)

    In a multicenter, randomized, observer-blinded, controlled study conducted in the United States, the immune responses to each of the antigens contained in BOOSTRIX were evaluated in sera obtained approximately 1 month after administration of a single dose of vaccine to adolescent subjects (aged 10 to 18 years). Of the subjects enrolled in this study, approximately 76% were aged 10 to 14 years and 24% were aged 15 to 18 years. Approximately 98% of participants in this study had received the recommended series of 4 or 5 doses of either DTwP or a combination of DTwP and DTaP in childhood. The racial/ethnic demographics were as follows: White 85.8%, Black 5.7%, Hispanic 5.6%, Oriental 0.8%, and other 2.1%.

    Response to Tetanus and Diphtheria Toxoids: The antibody responses to the tetanus and diphtheria toxoids of BOOSTRIX compared with Td vaccine are shown in Table 8. One month after a single dose, anti-tetanus and anti-diphtheria seroprotective rates (≥0.1 IU/mL by ELISA) and booster response rates were comparable between BOOSTRIX and the comparator Td vaccine.

    Adults (Aged 19 to 64 Years)

    A multicenter, randomized, observer-blinded study, conducted in the United States, evaluated the immunogenicity of BOOSTRIX compared with the licensed comparator Tdap vaccine (Sanofi Pasteur). Vaccines were administered as a single dose to subjects (N = 2,284) who had not received a tetanus-diphtheria booster within 5 years. The immune responses to each of the antigens contained in BOOSTRIX were evaluated in sera obtained approximately 1 month after administration. Approximately 33% of subjects were aged 19 to 29 years, 33% were aged 30 to 49 years, and 34% were aged 50 to 64 years. Among subjects in the combined vaccine groups, 62% were female; 84% of subjects were White, 8% Black, 1% Asian, and 7% were of other racial/ethnic groups.

    Response to Tetanus and Diphtheria Toxoids: The antibody responses to the tetanus and diphtheria toxoids of BOOSTRIX compared with the comparator Tdap vaccine are shown in Table 11. One month after a single dose, anti-tetanus and anti-diphtheria seroprotective rates (≥0.1 IU/mL by ELISA) were comparable between BOOSTRIX and the comparator Tdap vaccine.

    Elderly (Aged 65 Years and Older)

    The U.S. elderly (aged 65 years and older) study, a randomized, observer-blinded study, evaluated the immunogenicity of BOOSTRIX (n = 887) compared with a U.S.-licensed comparator Td vaccine (n = 445) (Sanofi Pasteur). Vaccines were administered as a single dose to subjects who had not received a tetanus-diphtheria booster within 5 years. Among all vaccine recipients, the mean age was approximately 72 years; 54% were female and 95% were White. The immune responses to each of the antigens contained in BOOSTRIX were evaluated in sera obtained approximately 1 month after administration.

    Response to Tetanus and Diphtheria Toxoids: Immune responses to tetanus and diphtheria toxoids were measured 1 month after administration of a single dose of BOOSTRIX or a comparator Td vaccine. Anti-tetanus and anti-diphtheria seroprotective rates (≥0.1 IU/mL) were comparable between BOOSTRIX and the comparator Td vaccine (Table 14).

    14.3 Immunological Evaluation following Revaccination with BOOSTRIX

    Adults (Aged 20 to 29 Years)

    A multicenter, open-label, controlled study conducted in the United States evaluated the immunogenicity of BOOSTRIX in adults aged 20 to 29 years who received an initial dose of BOOSTRIX (n = 128) or the comparator Td vaccine (MassBiologics) (n = 37) in the U.S. adolescent (aged 10 to 18 years) study. BOOSTRIX was administered to all subjects 10 years after initial vaccination. The immune responses to each of the antigens contained in BOOSTRIX were evaluated in sera obtained approximately 1 month after vaccine administration. Among all vaccine recipients, the mean age was 23.5 years; 45.5% were female, and 87.9% were White.

    Response to Tetanus and Diphtheria Toxoids: The antibody responses to the tetanus and diphtheria toxoids of BOOSTRIX are shown in Table 16. One month after vaccination, anti-tetanus and anti-diphtheria seroprotective rates (≥0.1 IU/mL by ELISA) were comparable between groups.

    Response to Pertussis Antigens: The GMCs to each of the pertussis antigens 1 month following a dose of BOOSTRIX in subjects who had received an initial dose of BOOSTRIX or the licensed comparator Tdap vaccine (Sanofi Pasteur) 9 years earlier were compared with the GMCs of infants following a 3-dose primary series of PEDIARIX [see Clinical Studies (14.1)].Table 19 presents the results for the ATP cohort for immunogenicity in both studies. Anti-PT, anti-FHA, and anti-PRN antibody concentrations observed in adults 1 month after a dose of BOOSTRIX were non-inferior to those of infants following a primary vaccination series with PEDIARIX.

    Compared with the Control Group, non-inferiority of booster response rates to the pertussis antigens following a dose of BOOSTRIX in subjects who had received an initial dose of BOOSTRIX or another licensed Tdap vaccine (Sanofi Pasteur) was achieved for the PT antigen [BOOSTRIX minus Control Group] and the FHA antigen [Tdap minus Control Group], respectively (Table 20). Non-inferiority was not achieved for FHA and PRN booster response rates [BOOSTRIX minus Control Group] or for PT and PRN booster response rates [Tdap minus Control Group].

    14.4 Concomitant Administration with Meningococcal Conjugate Vaccine

    The concomitant use of BOOSTRIX and a tetravalent meningococcal (groups A, C, Y, and W-135) conjugate vaccine (Sanofi Pasteur) was evaluated in a randomized study in healthy adolescents aged 11 to 18 years. A total of 1,341 adolescents were vaccinated with BOOSTRIX. Of these, 446 subjects received BOOSTRIX administered concomitantly with meningococcal conjugate vaccine at different injection sites, 446 subjects received BOOSTRIX followed by meningococcal conjugate vaccine 1 month later, and 449 subjects received meningococcal conjugate vaccine followed by BOOSTRIX 1 month later.

    Immune responses to diphtheria and tetanus toxoids (% of subjects with anti-tetanus and anti-diphtheria antibodies ≥1.0 IU/mL by ELISA), pertussis antigens (booster responses and GMCs), and meningococcal antigens (vaccine responses) were measured 1 month (range: 30 to 48 days) after concomitant or separate administration of BOOSTRIX and meningococcal conjugate vaccine. For BOOSTRIX given concomitantly with meningococcal conjugate vaccine compared with BOOSTRIX administered first, non-inferiority was demonstrated for all antigens, with the exception of the anti-PRN GMC. The lower limit of the 95% CI for the GMC ratio was 0.54 for anti-PRN (pre-specified limit ≥0.67). For the anti-PRN booster response, non-inferiority was demonstrated. It is not known if the efficacy of BOOSTRIX is affected by the reduced response to PRN.

    There was no evidence that BOOSTRIX interfered with the antibody responses to the meningococcal antigens when measured by rabbit serum bactericidal assays (rSBA) when given concomitantly or sequentially (meningococcal conjugate vaccine followed by BOOSTRIX or BOOSTRIX followed by meningococcal conjugate vaccine).

    14.5 Concomitant Administration with FLUARIX (Inactivated Influenza Vaccine)

    The concomitant use of BOOSTRIX and FLUARIX was evaluated in a multicenter, open-label, randomized, controlled study of 1,497 adults aged 19 to 64 years. In one group, subjects received BOOSTRIX and FLUARIX concurrently (n = 748). The other group received FLUARIX at the first visit, then 1 month later received BOOSTRIX (n = 749). Sera was obtained prior to and 1 month following concomitant or separate administration of BOOSTRIX and/or FLUARIX, as well as 1 month after the separate administration of FLUARIX.

    Immune responses following concurrent administration of BOOSTRIX and FLUARIX were non-inferior to separate administration for diphtheria (seroprotection defined as ≥0.1 IU/mL), tetanus (seroprotection defined as ≥0.1 IU/mL and based on concentrations ≥1.0 IU/mL), PT antigen (anti-PT GMC), and influenza antigens (percent of subjects with hemagglutination-inhibition [HI] antibody titer ≥1:40 and ≥4-fold rise in HI titer). Non-inferiority criteria were not met for the anti-pertussis antigens FHA and PRN. The lower limit of the 95% CI of the GMC ratio was 0.64 for anti-FHA and 0.60 for anti-PRN and the pre-specified limit was ≥0.67. It is not known if the efficacy of BOOSTRIX is affected by the reduced response to FHA and PRN.
