Comparison of DTaP-IPV-Hep B-PRP~T Combined Vaccine to CombAct-HIB® Concomitantly Given With Engerix B® Paediatric and OPV
- Conditions
- Hepatitis BPolioDiphtheriaPertussisHaemophilus Influenzae Type b
- Registration Number
- NCT00362336
- Lead Sponsor
- Sanofi Pasteur, a Sanofi Company
- Brief Summary
The purpose of this study is to document the immunological response to the investigational hexavalent vaccine at the 6, 10, and 14 weeks schedule
The primary objective is to demonstrate that the hexavalent DTaP-IPV-HB-PRP\~T combined vaccine does not induce lower immune responses than CombAct-HIB® with Engerix B® Paediatric and OPV in terms of seroprotection rates to Diphtheria (D), Tetanus (T), polio, Hepatitis B (HB), and Polyribosyl ribitol phosphate (PRP), one month after a 3-dose primary series (6, 10, and 14 weeks) with no HB vaccination at birth.
The secondary Objectives are:
To describe the safety in terms of any adverse events in the first 28 days after each injection and any serious adverse events during the entire trial.
To describe Immunogenicity after the primary series and prior to and after a booster vaccination.

- Primary Outcome Measures
Name Time Method Number of Participants With Seroprotection After Primary Series Vaccination With DTaP-IPV-Hep B-PRT~T or CombAct Hib™ + Engerix B™ + Oral Polio Vaccine (OPV) 1 month post-Dose 3 Antibodies were measured by the following methods: anti-Hepatitis B (Hep B) by enhanced chemiluminescence detection, anti-Haemophilus influenzae type b (Hib) by Farr type radio immunoassay, anti-Diphtheria (D) by toxin neutralization assay, anti-Tetanus (T) by indirect enzyme-linked immunosorbent assay (ELISA), and anti-Poliovirus types 1, 2, and 3 by neutralization assay. Seroprotection was defined as the following antibody titers: Anti-Tetanus ≥ 0.01 International Unit (IU)/mL; Anti-Diphtheria ≥ 0.01 IU/mL; Anti-Hepatitis B ≥ 10 mIU/mL; Anti-Polyribosyl ribitol phosphate ≥ 0.15 µg/mL; Anti-polio 1, 2, and 3 ≥ 8 (1/dil).

Name Time Method Number of Participants Attaining Other Seroprotection and Seroconversion Titers After Primary Series Vaccination With DTaP-IPV-Hep B-PRT~T (With or Without Engerix B™ at Birth) or CombAct Hib™ + Engerix B™ + Oral Polio Vaccine (OPV) 1 month post-Dose 3 Anti-Hepatitis B (Hep B) was measured by enhanced chemiluminescence detection, anti-Haemophilus influenzae type b (Hib) by Farr type radio immunoassay, anti diphtheria by toxin neutralization assay, anti-Tetanus (T) by indirect enzyme-linked immunosorbent assay (ELISA), and anti-Pertussis toxoid (PT) and anti-Filamentous hemagglutinin (FHA) by ELISA. Seroprotection was defined as a titer ≥ 100 mIU/mL for anti-Hep B; ≥ 1 µg/mL for anti-PRP; ≥ 0.1 IU/mL (Level 1) and ≥ 1.0 IU/mL (Level 2) for anti-Diphtheria and anti-Tetanus. Seroconversion for anti-PT and anti-FHA was a ≥ 4-fold increase from baseline.
