研究概览
简要总结
The study was designed to compare the safety and immunogenicity of DTap-IPV with DAPTACEL® + IPOL® as the 5th dose booster in children ≥ 4 to < 7 years of age in the US and Puerto Rico who were previously vaccinated with DAPTACEL® and/or Pentacel® vaccines only.
Primary Objectives:
- To compare the pertussis [Pertussis Toxoid (PT), Filamentous Haemagglutinin (FHA), Pertactin (PRN), and Fimbriae Types 2 and 3 (FIM)] booster responses and geometric mean concentrations (GMCs) (as measured by enzyme-linked immunosorbent assay [ELISA]) following DTap-IPV vaccination to those elicited following DAPTACEL® + IPOL® vaccination when administered as a 5th dose.
- To compare the diphtheria and tetanus booster responses and GMCs (as measured by ELISA) following DTap-IPV vaccination with those elicited following DAPTACEL® + IPOL® vaccinations when administered as a 5th dose .
- To compare the Inactivated Poliovirus Vaccine booster responses (as measured by neutralizing assay) following DTap-IPV vaccination with those elicited following DAPTACEL® + IPOL® vaccinations.
Observational Objectives:
- To compare the polio (types 1, 2, and 3) geometric mean titers (GMTs) following DTap-IPV vaccination with those elicited following DAPTACEL® + IPOL® vaccinations.
- To assess the safety of DTap-IPV vaccine or DAPTACEL® + IPOL® vaccine when administered as the fifth dose booster vaccine in participants previously vaccinated with DAPTACEL and/or Pentacel vaccines.
详细描述
All participants will be randomized to receive either one dose each of DTap-IPV + Measles, Mumps, and Rubella Virus Vaccine Live (M-M-R®II) + VARIVAX® or one dose each of DAPTACEL® + IPOL® + M-M-R®II + VARIVAX® on Day 0.

结局指标
主要结局
Geometric Mean Concentrations of the Pertussis Antibodies Before and Following Vaccination With Either DTaP-IPV or DAPTACEL® + IPOL® Vaccine
时间窗: Day 0 (pre-vaccination) and Day 28 post-vaccination
Geometric mean concentrations to pertussis antigens (pertussis toxoid \[PT\], filamentous hemagglutinin \[FHA\], pertactin \[PRN\], and fimbriae types 2 and 3 \[FIM\]) were measured by enzyme-linked immunosorbent assay (ELISA).
Geometric Mean Concentrations of the Tetanus and Diphtheria Antibodies Before and Following Vaccination With Either DTaP-IPV or DAPTACEL® + IPOL® Vaccine
时间窗: Day 0 (pre-vaccination) and Day 28 post-vaccination
Geometric mean concentrations to anti-tetanus and anti-diphtheria were measured by enzyme-linked immunosorbent assay (ELISA).
Number of Participants With Booster Response to Tetanus and Diphtheria Antigens Following Vaccination With Either DTaP-IPV or DAPTACEL® + IPOL® Vaccine
时间窗: Day 0 (pre-vaccination) and Day 28 post-vaccination
Anti-Tetanus antibodies were measured by enzyme-linked immunosorbent assay (ELISA). Anti-Diphtheria antibodies were measured by a toxin neutralization test. Booster responses were defined as participants with a pre-vaccination antibody concentration \<0.1 IU/ml, achieving a post-vaccination level ≥0.4 IU/ml, or a pre-vaccination antibody concentration ≥0.1 IU/ml but \<2.0 IU/ml, achieving a 4-fold rise rate post-vaccination, or a pre-vaccination antibody concentration ≥2.0 IU/ml, achieving a 2-fold response.
Number of Participants With Booster Response to the Pertussis Antigens Following Vaccination With Either DTaP-IPV or DAPTACEL® + IPOL® Vaccine
时间窗: Day 0 (pre-vaccination) and Day 28 post-vaccination
Booster responses to pertussis antigens \[pertussis toxoid (PT), filamentous hemagglutinin (FHA), pertactin (PRN), and fimbriae types 2 and 3 (FIM)\] were measured by enzyme-linked immunosorbent assay (ELISA). Booster responses were defined as participants with either a pre-vaccination antibody concentration less than lower limit of quantitation (\<LLOQ), achieving a post-vaccination level ≥4X LLOQ, or pre-vaccination antibody concentrations ≥LLOQ but \<4X LLOQ, achieving a 4-fold rise rate of post-vaccination, or a pre-vaccination antibody concentration ≥4X LLOQ, achieving a 2-fold response.
