Study of DTaP-IPV-Hep B-PRP~T Combined Vaccine Compared to Infanrix®Hexa in Healthy Peruvian Infants

8. april 2016 opdateret af: Sanofi Pasteur, a Sanofi Company

Immunogenicity Study of DTaP-IPV-Hep B-PRP~T Combined Vaccine in Comparison to Infanrix®Hexa, at 2-4-6 Months of Age in Healthy Peruvian Infants

The study aims to confirm that, in Peruvian infants, the investigational DTaP-IPV Hep B-PRP~T vaccine has immunological and safety profiles that are comparable to those of the control vaccine that is already marketed (Infanrix®Hexa)

Primary Objective:

To demonstrate that the hexavalent DTaP-IPV-Hep B-PRP~T combined vaccine induces an immune response that is at least as good as the response following Infanrix®Hexa in terms of seroprotection rates to HB, one month after a three-dose primary series (2, 4 and 6 months)

Secondary Objectives:

  • To describe in each group the immunogenicity to vaccine components (for DTaP-IPV-Hep B-PRP~T and Infanrix®Hexa) one month after the third dose of the primary series.
  • To assess the overall safety in each group one month after each dose of the primary series and through the entire study.

  • Known systemic hypersensitivity to any of the vaccine components or history of a life threatening reaction to the trial vaccine or a vaccine containing the same substances
  • Congenital or acquired immunodeficiency, or immunosuppressive therapy such as long-term (for more than 2 weeks) systemic corticosteroid therapy within the last four weeks
  • Chronic illness at a stage that could interfere with trial conduct or completion
  • Blood or blood-derived products received since birth
  • Any vaccination in the 4 weeks preceding the first trial vaccination
  • Any planned vaccination during the trial (until Visit 06), except the study vaccines, rotavirus vaccine and pneumococcal conjugate vaccines
  • Documented history of pertussis, tetanus, diphtheria, poliomyelitis, hepatitis B or Haemophilus influenzae type b infection(s) (confirmed either clinically, serologically, or microbiologically)
  • Previous vaccination against pertussis, tetanus, diphtheria, poliomyelitis, hepatitis B or Haemophilus influenzae type b infection(s)
  • Known personal or maternal history of Human Immunodeficiency Virus, hepatitis B or hepatitis C seropositivity
  • Known thrombocytopenia or bleeding disorder contraindicating intramuscular vaccination

Number of Participants Achieving Seroprotection for Anti Hep-B After a Primary Series of Vaccination With Either DTaP-IPV-Hep B-PRP~T or Infanrix Hexa™
Tidsramme: Day 150 (1 month after dose 3)
Anti-hepatitis B (Hep B) antibodies were measured by chemiluminescence detection. Seroprotection was defined as a titer ≥ 10 mIU/mL.
Day 150 (1 month after dose 3)
Number of Participants Achieving Seroprotection to Vaccine Antigens After a Primary Series Vaccination With Either DTaP-IPV-Hep B-PRP~T or Infanrix Hexa™ Vaccine.
Tidsramme: Day 150 (1 month after dose 3)

Antibody titers were measured by chemiluminescence detection for hepatitis B (Hep B), by Farr type radioimmunoassay for Haemophilus influenzae type b (PRP), and by toxin neutralization test for diphtheria. Seroprotection criteria were defined as:

Criteria 1: Anti-Hep B titer ≥ 10 mIU/mL; Anti-PRP titer ≥ 0.15 µg/mL; Anti-diphtheria titer ≥ 0.01 IU/mL.

Criteria 2: Anti-Hep B titer ≥ 100 mIU/mL; Anti-PRP titer ≥ 1 µg/mL; Anti-diphtheria titer or ≥ 0.1 IU/mL.
