Primary & Booster Immunogenicity Study of GSK Biologicals' Hib-MenC Versus a Licensed Men-C Vaccine

Phase 3

Completed

• Conditions: Haemophilus Influenzae Type b; Neisseria Meningitidis

• Registration Number: NCT00258700
• Lead Sponsor: GlaxoSmithKline

Brief Summary

The purpose of this study is to demonstrate the non-inferiority of the candidate Hib-MenC conjugate vaccine co-administered with Infanrix™-IPV versus a licensed meningococcal serogroup C vaccine co-administered with Pediacel™ when given according to a 2, 3, 4 month schedule and the immunogenicity of the Hib-MenC vaccine when given as a booster dose at 12-15 months of age.

Detailed Description

This multicenter study is open with respect to the treatment allocation, but double-blind with respect to the Hib-MenC-TT lots (3 lots). The study will be conducted in two stages. Primary vaccination phase: 3 doses Hib-MenC-TT with Infanrix™-IPV or for the control group a licensed Men-C vaccine with Pediacel™ at 2, 3, 4 months of age; Booster/persistence phase: 1 dose Hib-MenC with Priorix™. 4 blood samples of 3.5ml (5ml for the UK subset) are collected (Study Months 0 \& 3, prior to \& 42 days after the booster).
