General information about the trial
|
|||
Main objective of the trial |
To demonstrate the non-inferiority of Varilrix HSA-free vaccine as compared to Varilrix vaccine in terms of geometric mean titer (GMT) of varicella zoster virus (VZV) antibodies 43-57 days after the first dose vaccination.
Criterion for non-inferiority: The lower limit of the 95% confidence interval (CI) for the GMT ratio (derived from immunofluorescence assay [IFA]) between Group Varilrix HSA free and (divided by) Group Varilrix is equal to or above the pre-defined clinical limit of 0.5.
If this first criterion was met, an additional criterion was to be tested.
Additional criterion of non-inferiority: The lower limit of the 95% CI for the GMC ratio (derived from ELISA) between Group Varilrix HSA-free and (divided by) Group Varilrix is equal to or above the pre-defined clinical limit of 0.67
|
||
Protection of trial subjects |
The subjects were observed closely for at least 30 minutes following the administration of vaccines, with appropriate medical treatment readily available in case of a rare anaphylactic reaction.
