研究概览
简要总结
The purpose of this study is to generate immunogenicity and safety data of an investigational hexavalent DTaP-IPV-Hep B-PRP-T vaccine compared to a control vaccine, Infanrix hexa™ when given along with Prevenar™ and Rotarix™ vaccines.
Primary Objectives:
- To demonstrate the equivalence of immunogenicity of 3 lots of DTaP-IPV-Hep B-PRP-T vaccine 1 month after a 3-dose primary series (2, 4 and 6 months) when given with Prevenar™ and Rotarix™, in terms of immunoresponses.
- To demonstrate the non-inferiority of the hexavalent DTaP-IPV-Hep B-PRP-T vaccine to the licensed hexavalent Infanrix hexa vaccine when given with Prevenar™ and Rotarix™.
Secondary Objectives:
- To describe in each group the immunogenicity parameters for all antigens for each vaccine
- To assess the safety profile in terms of solicited and unsolicited adverse events and serious adverse events in each group for each vaccine.
详细描述
Each participant will receive 3 doses of 1 of 3 lots of the investigational hexavalent vaccine or the control vaccine, Infanrix hexa™, administered with Prevenar™ at 2, 4, and 6 months of age and Rotarix™ at 2 and 4 months of age.
All participants will be monitored for safety for 6 months after the last injection of the primary vaccination series.

结局指标
主要结局
Geometric Mean Titers (GMTs) of Anti-Hepatitis B Before and After 3 Dose Primary Vaccination With Either DTaP-IPV-Hep B-PRP~T Batch A, B, or C, or Infanrix Hexa™
时间窗: Day 0 (pre-vaccination) Dose 1 and 30 days post-vaccination
Antibodies against Hepatitis B (Hep B) were measured by chemiluminescence detection.
Number of Participants With Seroprotection or Vaccine Response After Vaccination With Either DTaP-IPV-Hep B-PRP~T or Infanrix Hexa Vaccine
时间窗: 30 Days post-dose 3
Seroprotection was defined as titers ≥ 0.01 IU/mL for Diphtheria (D) and Tetanus (T); ≥ 10 IU/mL for Hep B; ≥ 0.15 µg/mL for PRP, and ≥ 8 (1/dil) for Poliovirus. Vaccine response for PT and FHA were defined as a titer ≥ lower limit of quantitation (LLOQ) in initially seronegative participants, or at least persistence (post-vaccination titer ≥ pre-vaccination titer) in initially seropositive subjects (titer ≥ LLOQ).
次要结局
- Geometric Mean Titers (GMTs) of Antibodies After Vaccination With Either DTaP-IPV-Hep B-PRP~T or Infanrix Hexa Vaccine(Day 0 (pre-vaccination) and 30 days post-dose 3)
- Number of Participants Reporting at Least One Solicited Injection Site (Study Vaccine) or Systemic Reactions After Vaccination With Either DTaP-IPV-Hep B-PRP~T or Infanrix Hexa Vaccine(Day 0 up to 7 after each dose)
- Number of Participants Reporting at Least One Solicited Injection Site Reaction at the Prevenar Injection Site After Vaccination With Either DTaP-IPV-Hep B-PRP~T or Infanrix Hexa™ Vaccine(Day 0 up to 7 post each vaccination)
