Clinical Trial Summary

The purpose of this study is to evaluate the immunogenicity, safety and tolerability of rMenB+OMV NZ and MenACWY vaccines when concomitantly administered to healthy subjects 16-18 years of age.

Description:

As per the recommendation from Center for Biologics Evaluation and Research (CBER) the study has been amended to include a new "agar-overlay" serum bactericidal assay using human serum complement (hSBA). Additional changes include validation of the MenB manual to measure immunogenicity of the meningococcal group B vaccine, a modification in the definition of 4-fold increase in post-vaccination hSBA titer definition when the pre-vaccination titer is below the limit of detection, and a modification in the population set to be used for safety analysis wherein the exposed set is to be used for all safety analyses.
