Assessing the Effectiveness, Immunogenicity and Safety of Meningococcal ABCWY Vaccine Administered to Healthy Adolescents

22 de agosto de 2018 atualizado por: GlaxoSmithKline

A Phase 2b, Controlled, Observer-Blind, Multi-Center Study Assessing the Effectiveness, Immunogenicity and Safety of the 3rd Dose of Novartis Meningococcal ABCWY Vaccine Administered to Healthy Adolescents in the U.S.

This is extension of the V102_16 study (NCT02140762). V102_16E1 is designed to assess the effectiveness of a 3-dose vaccination series of MenABCWY, administered according to 0, 2, 6 month schedule, against the same panel of endemic US N. meningitidis serogroup B strains, as measured by enc-hSBA assay. The subjects who completed the parent V102_16 study will be invited at the time of their last study visit to participate in this extension study.
