研究概览
简要总结
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.
详细描述
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.

结局指标
主要结局
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™
时间窗: 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.
时间窗: 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.
次要结局

- 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))
