Interchangeability of Infanrix™ IPV/Hib and Pediacel® at 2,4 & 6 Months of Age

June 14, 2011 updated by: Dalhousie University

Safety and Immunogenicity of Two Mixed Primary Immunization Schedules: Pediacel® at 2 and 4 Months of Age Followed by One Dose of Infanrix™ IPV/Hib at 6 Months of Age; and, Infanrix™ IPV/Hib at 2 Months of Age, Followed by Pediacel® at 4 and 6 Months of Age

To demonstrate the safety and immunogenicity of two mixed primary immunization schedules: Pediacel® at 2 and 4 months of age followed by one dose of Infanrix™ IPV/Hib at 6 months of age; and, Infanrix™ IPV/Hib at 2 months of age, followed by Pediacel® at 4 and 6 months of age.

Study Overview

Status

Completed

Detailed Description

Immunogenicity will be evaluated using the following:

Serological outcome measures will be assessed on day 0 (visit 1) and 28-42 days after the 3rd dose of the primary series for both groups:

  • Seroprotection rates for antibodies against PRP (anti-PRP), defined as percentage of subjects with antibody concentrations ≥ 0.15 µg/ml and ≥ 1.0 µg/ml.
  • Geometric mean concentration (GMC) for antibodies against PT, FHA, PRN, and FIM.
  • Anti-pertussis antibody concentrations ≥4-fold rise (post-Dose 3/pre-Dose 1).

Safety will be evaluated using the following:

  • Occurrence, time to onset, number of days of occurrence, severity and seriousness of solicited injection site reactions (tenderness, erythema, swelling) and systemic symptoms (fever, vomiting, crying abnormal, drowsiness, appetite decreased, irritability) within 8 days (Day 0 - Day 7) after each vaccination and across all vaccinations.
  • Occurrence, nature, time to onset, duration, severity, and relationship to vaccination of unsolicited adverse events (AE) occurring within 31 days (Day 0 -Day 30) of each vaccination.
  • Occurrence, nature, time to onset, duration, and relationship to vaccination of any serious adverse events (SAE) during the entire study period for all groups.

Description

Inclusion Criteria:

  1. Infants aged 6 wks (42 days) to 2 months (1 day before they turn 3 months) inclusive on the day of inclusion.
  2. Born at full term of pregnancy (defined as ≥37 weeks, 0 days).

  6. Parent or legally authorized representative able to read and write in English or French.

Exclusion Criteria:

  1. Participation in another clinical trial in the 4 weeks preceding the first trial vaccination.
  2. Planned participation in another clinical trial during the present trial period.
  3. Personal history of congenital or acquired immunodeficiency, immunosuppressive therapy such as long-term systemic corticosteroids therapy.
  4. Known or suspected systemic hypersensitivity to any of the vaccine components or history of a life-threatening reaction to a vaccine containing the same substances as the trial vaccine(s).
  5. Chronic illness that could interfere with trial conduct or completion.
  6. Received blood or blood-derived products since birth.
  7. Any vaccination preceding the first trial vaccination, except vaccinations recommended as part of the infant schedule.
  8. Previous vaccination with any acellular pertussis- (DTaP) or whole cell pertussis-DTwP) based combination vaccines, Haemophilus influenzae type b Hib)conjugate,or poliovirus vaccines.
  9. Coagulation disorder contraindicating intramuscular vaccination.
  10. Clinically significant findings on review of systems (determined by investigator or sub-investigator to be sufficient for exclusion).
  11. Developmental delay or neurological disorder.
  12. Any condition which, in the opinion of the investigator, would interfere with the evaluation of the vaccine or pose a health risk to the subject.
  13. History of Hib, diphtheria, tetanus, pertussis or poliovirus disease.
