Evaluation of the Immunogenicity, Safety and Reactogenicity of the Combined DTPa-IPV Vaccine in Healthy Infants

Phase 3
Completed
Conditions
Acellular Pertussis
Diphtheria
Tetanus
Interventions
Biological: DTPa-IPV
Biological: DTPa
Biological: IMOVAX Polio®
Registration Number
NCT00290342
Lead Sponsor
GlaxoSmithKline
Brief Summary

DTPa and IPV vaccines are recommended for immunization of infants in Korea. The use of combination vaccines simplifies routine paediatric vaccination. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.

Detailed Description

Participants in this Phase IIIb study will either receive GSK Biologicals' combined diphtheria-tetanus-acellular pertussis-inactivated poliovirus (DTPa-IPV) vaccine or co-administration of GSK Biologicals' combined diphtheria-tetanus-acellular pertussis (DTPa) vaccine and Sanofi-Pasteurs' inactivated poliovirus vaccine. Vaccines for both groups will be administered at 2, 4 and 6 months of age. Two blood samples will be collected during the course of the study: prior to vaccination and one month after the third vaccine dose.

Infanrix-IPV GroupDTPa-IPVHealthy male or female subjects between and including 8 to 12 weeks (56-90 days) of age at the time of the first vaccination, who were born after a gestation period of 36 to 42 weeks, received 3 doses of the GSK Biologicals' combined Infanrix™-IPV (DTPa-IPV) vaccine at 2, 4 and 6 months of age, intramuscularly into the antero-lateral thigh.
Infanrix + IMOVAX Polio GroupDTPaHealthy male or female subjects between and including 8 to 12 weeks (56-90 days) of age at the time of the first vaccination, who were born after a gestation period of 36 to 42 weeks, received 3 doses of the GSK Biologicals' Infanrix™ (DTPa) vaccine co-administered with Sanofi-Pasteur's IMOVAX Polio® (IPV) vaccine at 2, 4 and 6 months of age, intramuscularly into the antero-lateral sides of opposite thighs.

Primary Outcome Measures
NameTimeMethod
Number of Seroprotected Subjects Against Poliovirus (Anti-polio) Types 1, 2 and 3One month (Month 5) post-primary vaccination course

A seroprotected subject was defined as a vaccinated subject with anti-poliovirus types 1, 2 and 3 (Anti-Polio 1, 2 and 3) antibody titers greater than or equal to (≥) the cut-off value of 8.

Number of Seroprotected Subjects Against Diphtheria (Anti-D) and Tetanus (Anti-T)One month (Month 5) post-primary vaccination course

A seroprotected subject was defined as a vaccinated subject with anti-diphteria (anti-D) and anti-tetanus (anti-T) antibody concentrations greater than or equal to (≥) the cut-off value of 0.1 international units/milliliter (IU//mL).

Number of Subjects With Vaccine Response to Pertussis Toxoid (PT), Pertactin (PRN) and Filamentous Haemagglutinin (FHA) AntigensOne month (Month 5) post-primary vaccination course

Vaccine response to pertussis toxoid (PT), pertactin (PRN) and filamentous haemagglutinin (FHA) was defined as the appearance of antibodies in subjects who were initially (i.e. before vaccination) seronegative (i.e. with concentrations \< 5 EL.U/mL), or at least as the maintenance of pre-vaccination antibody concentrations in subjects who were initially seropositive (i.e. with concentrations ≥ 5 EL.U/mL value).

Number of Subjects With a Vaccine Response for Anti-pertussis Toxoid (Anti-PT), Anti-pertactin (Anti-PRN) and Anti-filamentous Haemagglutinin (Anti-FHA)One month (Month 5) post-primary vaccination course

Vaccine response was defined as: - for initially seronegative subjects, antibody concentrations ≥ 5 EL.U/mL one month after third vaccine dose; - for initially seropositive subjects, at least maintenance of pre-vaccination antibody concentrations one month after third vaccine dose.

Secondary Outcome Measures
NameTimeMethod
Number of Subjects Reporting Any Serious Adverse Events (SAEs)During the entire study period (from Month 0 up to Month 5)

Serious adverse events (SAEs) assessed include medical occurrences that result in death, are life threatening, require hospitalization or prolongation of hospitalization or result in disability/incapacity.

Concentration of Antibodies Against Diphteria (Anti-D) and Tetanus (Anti-T)Before (Pre) and one month after (Post) the primary vaccination course

Concentrations are presented as geometric mean concentrations (GMCs), expressed in international units per millilitre (mIU/mL).

Number of Seroprotected Subjects Against Diphtheria (Anti-D) and Tetanus (Anti-T)Before (Pre) and one month after (Post) the primary vaccination course

A seroprotected subject was defined as a vaccinated subject with anti-diphteria (anti-D) and anti-tetanus (anti-T) antibody concentrations greater than or equal to (≥) the cut-off value of 1 international units/milliliter (IU//mL).

Titers for Poliovirus Type 1, 2 and 3 AntibodiesBefore (Pre) and one month after (Post) the primary vaccination course

Titers for anti-polio 1, 2 and 3 are presented as geometric mean titers (GMTs). The reference seropositivity cut-off value was greater than or equal to (≥) 8.

Concentrations of Antibodies Against Pertussis Toxoid (Anti-PT), Pertactin (Anti-PRN) and Filamentous Haemagglutinin (Anti-FHA)Before (Pre) and one month after (Post) the primary vaccination course

Concentrations are presented as geometric mean concentrations (GMCs), expressed in ELISA units per millilitre (EL.U/mL).

Number of Subjects Reporting Solicited Local SymptomsDuring the 4-day (Days 0-3) post-vaccination period, across doses

Assessed solicited local symptoms were pain, redness and swelling. Any = occurrence of the symptom regardless of intensity grade. Grade 3 pain = crying when limb was moved/spontaneously painful. Grade 3 redness/swelling = redness/swelling spreading beyond 20 millimeters (mm) of injection site.

Number of Subjects Reporting Solicited General SymptomsDuring the 4-day (Days 0-3) post-vaccination period, across doses

Assessed solicited general symptoms were drowsiness, fever \[defined as axillary temperature equal to or above 37.5 degrees Celsius (°C)\], irritability and loss of appetite. Any = occurrence of the symptom regardless of intensity grade. Grade 3 drowsiness = drowsiness that prevented normal activity. Grade 3 fever = fever \> 39.0 °C. Grade 3 irritability = crying that could not be comforted/ prevented normal activity. Grade 3 Loss of appetite = not eating at all. Related = symptom symptoms considered by the investigator to have a causal relationship to vaccination.

Number of Subjects Reporting Any Unsolicited Adverse Events (AEs)During the 31-day (Days 0-30) post-vaccination period

An unsolicited AE covers any untoward medical occurrence in a clinical investigation subject temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product and reported in addition to those solicited during the clinical study and any solicited symptom with onset outside the specified period of follow-up for solicited symptoms. Any was defined as the occurrence of any unsolicited AE regardless of intensity grade or relation to vaccination.
