General information about the trial
|
|||
Main objective of the trial |
This study evaluated the immunogenicity, safety, and tolerability of VARIVAX® (Varicella Virus Vaccine Live) manufactured with a new passage extension (PE34) process compared with the VARIVAX® 2016 commercial process. The primary hypotheses being tested were that antibody response rate and mean antibody titer induced at 6 weeks after a single vaccination by VARIVAX® PE34 Process are non-inferior to those induced by VARIVAX® 2016 commercial process, and that antibody response rate induced by VARIVAX® PE34 Process is acceptable.

Protection of trial subjects |
This study was conducted in conformance with Good Clinical Practice standards and applicable country and/or local statutes and regulations regarding ethical committee review, informed consent, and the protection of human subjects participating in biomedical research.

End point description |
The varicella zoster virus (VZV) antibody response rate was defined as the percentage of participants with VZV antibody titer ≥5 glycoprotein enzyme-linked immunosorbent assay (gpELISA) units/mL among participants who were seronegative to VZV (titers <1.25 gpELISA units/mL) at baseline. The analysis population included the number of participants with seronegative antibody titer (<1.25 gpELISA units/mL) at baseline and postvaccination serology.

Percentage of Participants with One or More Adverse Events | ||||||||||||
End point description |
An adverse event (AE) is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol-specified procedure. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition that is temporally associated with the use of the Sponsor’s product, is also an AE. The percentage of participants with one or more adverse events for Day 1 through Day 42 after vaccination 1 and Day 1 through Day 42 after vaccination 2 was reported.
