General information about the trial
|
|||
Main objective of the trial |
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 Hep B and PRP, 1 month after a three-dose primary series (at 2, 4, and 6 months), when co-administered with Prevnar™.
|
||
Protection of trial subjects |
Only subjects that met all the study inclusion and none of the exclusion criteria were randomized and vaccinated in the study. Vaccinations were performed by qualified and trained study personnel. Subjects with allergy to any of the vaccine components were not vaccinated. After vaccination, subjects were also kept under clinical observation for 30 minutes to ensure their safety. They were also followed up for a total of 300 days (including a 6 month safety follow up for SAEs) after the last vacine dose.
|
||
Background therapy |
All subjects in the study must have received Hep B vaccination at birth in order to comply with the Thai Standard Vaccination Schedule. | ||
Evidence for comparator |
Infanrix hexa™ is a licensed DTap/Hib/IPV/Hep B vaccine given in a three doses primary series vaccination. | ||

Blinding implementation details |
The investigator (blind observer or assessor) and subject’s parents or guardians did not know the vaccine administered. The assessor was in charge of the assessment of safety held in a separate room and away from where the vaccines were prepared. A nurse/vaccinator was in charge of the preparation and administration of the vaccine(s) in another room away from the assessor. When necessary the scratch off emergency decoding procedure described in the study protocol were to be followed.

Non inferiority of Hep B Seroprotection | |||||||||||||||
Statistical analysis description |
The differences in seroprotection rates for the Hep B and PRP antigens between the two groups (Test – Control) were calculated. The non inferiority margin for Hep B and PRP antigens was set to be –10%. The statistical method was based on the lower bound of the two sided 95% confidence interval (CI) of the difference of the seroprotection rates.

For each antigen, non inferiority for valence i was to be demonstrated if the lower limit of the two sided 95% CI was greater than -10. The primary objective (non inferiority of the investigational DTaP IPV Hep B PRP T vaccine) was not rejected for the Hep B and PRP since the lower bounds were > -10%.
