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

Phase 3
Completed
Conditions
Haemophilus Influenzae Type b
Hepatitis B
Pertussis
Diphtheria
Tetanus
Interventions
Biological: DTaP-HB-IPV and Haemophilus influenzae type b
Biological: DTaP IPV HB PRP~T vaccine
Registration Number
NCT00831753
Lead Sponsor
Sanofi Pasteur, a Sanofi Company
Brief Summary

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.

Detailed Description

The present trial will involve two-month old Peruvian infants, randomly assigned to receive three doses of either the investigational or the control vaccine at 2, 4, and 6 months of age.

Primary Outcome Measures
NameTimeMethod
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™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.

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.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.

Secondary Outcome Measures
NameTimeMethod
Number of Participants Reporting Solicited Injection Site or Solicited Systemic Reactions After Vaccination With Either DTaP-IPV-Hep B-PRP~T or Infanrix Hexa™ Vaccine.Day 0 up to Day 7 after each injection

Solicited Injection Site Reactions: Pain, Erythema, Swelling. Solicited Systemic Reactions: Pyrexia (Temperature), Vomiting, Crying, Somnolence, Anorexia, Irritability.

Grade 3 reactions were defined as: Pain, cries when injected limb is moved or movement of injected limb is reduced; Erythema and Swelling ≥ 5 cm; Pyrexia \> 39.5ºC; Vomiting ≥ 6 episodes per 24 hour or requiring parenteral hydration; Crying, \> 3 hours; Somnolence, sleeping most of the time or difficult to wake up; Anorexia refuses ≥ 3 feeds/meals or refuses most feeds/meals; Irritability inconsolable.

Geometric Mean Titers (GMTs) of Antibodies to Vaccine Antigens After a Primary Series of Vaccination With Either DTaP-IPV-Hep B-PRP~T or Infanrix Hexa™ Vaccine.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.
