Clinical Trial Results:
A phase III open-label randomised study to evaluate the immunogenicity and safety of the concomitant administration of a new Hexavalent DTaP-IPV-HB-Hib combined vaccine (Hexavalent vaccine) given at 2, 3, and 4 months of age with a meningococcal serogroup C conjugate (MenC) vaccine given at 2 and 4 months of age.
Short title:
Concomitant administration of a new hexavalent vaccine (Hexavalent vaccine) with a meningococcal serogroup C conjugate vaccine in healthy infants during primary series immunisation followed by booster vaccination
Due to the EudraCT – Results system being out of service between 31 July 2015 and 12 January 2016, these results have been published in compliance with revised timelines.

General information about the trial

Main objective of the trial |
PRIMARY SERIES (Period 2):
- To demonstrate that the concomitant administration of the Hexavalent vaccine given at 2, 3 and 4 months of age with a meningococcal serogroup C conjugate (MenC) vaccine given at 2 and 4 months of age is non inferior to the administration of the Hexavalent vaccine without a MenC vaccine concomitantly in term of seroprotection rate for hepatitis B 1 month after the 3rd dose of the Hexavalent vaccine.
- To demonstrate that the concomitant administration of a MenC vaccine given at 2 and 4 months of age with the Hexavalent vaccine given at 2, 3 and 4 months of age induces an acceptable response for MenC in term of seroprotection rate (SPR) 1 month after the 2nd dose of MenC.
BOOSTER (Period 3):
To describe the immunogenicity of a booster dose of the Hexavalent vaccine and of a meningococcal group ACWY conjugate vaccine either co-administered at 12 months of age or given separately.
|
||
Protection of trial subjects |
Subjects in the study received 3 injections during primary series (period 2) and 1 injection during the booster part (period 3) of a single dose of the study vaccine DTaP-IPV-HB-Hib supplied in a pre-filled 0.5 mL syringe that was administered by qualified study personnel.
Subjects with allergy to any of the vaccine components were not vaccinated.
After each vaccination, subjects were also kept under observation for 30 minutes to ensure their safety. Appropriate equipment was also available on site in case of any immediate allergic reactions.
|
||
Background therapy |
Not Applicable | ||
Evidence for comparator |

Blinding implementation details |
This was an open-label study as the number of vaccines administered in each group was different at several visits. Blinding would have required a placebo injection which was not deemed necessary since the primary end points were based on immunological criteria. Serology tests for the Hexavalent vaccine antigens were performed by laboratory staff blinded to subject group.

Notes [1] - The number of subjects starting the period is not consistent with the number completing the preceding period. It is expected the number of subjects starting the subsequent period will be the same as the number completing the preceding period. Justification: 34 subjects of the Primary Series period (period 2) were not randomised in the Booster period (period 3): 32 "screen failure", and 2 "non-compliance with the protocol". |

Notes [2] - No statistical analyses have been specified for this primary end point. It is expected there is at least one statistical analysis for each primary end point. Justification: There was no comparison between groups in this end point. As specified above, the immune response to MenC vaccine was considered as acceptable if the lower bound of the 2-sided 95.0% CI of the percentage of subjects with anti-MenC ≥8 (1/dil) 1 month after the 2nd dose was greater than 90%. Acceptability criteria was met for MenC. |
