Assess Immune Response Following Primary Vaccination With Tritanrix™-HepB Vaccine Mixed With 3 Formulations of Hib-MenAC Vaccine to Infants

Phase 2

Completed

• Conditions: Diphtheria; Tetanus; Pertussis; Hepatitis B; Hib Diseases; Neisseria Meningitidis Serogroups A & C Diseases

• Registration Number: NCT00291967
• Lead Sponsor: GlaxoSmithKline

Brief Summary

To compare three formulations of Hib-MenAC vaccines mixed with Tritanrix™-HepB vaccine with that of Tritanrix™-HepB vaccine concomitantly administered with GSK Biologicals' Hiberix™ vaccine and Tritanrix™-HepB vaccine mixed with Hiberix™ vaccine and concomitantly administered with Wyeth Lederle's meningococcal C conjugate vaccine (Meningitec™), with respect to antibody response to vaccine antigens (meningococcal serogroups A and C and PRP) after a three-dose primary vaccination course.

Detailed Description

Randomized study with five groups to receive one of the following vaccination regimens: One of the three formulations of GSK Biologicals' Hib-MenAC mixed with GSK Biologicals' Tritanrix™-HepB (3 different groups) GSK Biologicals' Tritanrix™-HepB + GSK Biologicals' Hiberix™ GSK Biologicals' Tritanrix™-HepB mixed with GSK Biologicals' Hiberix™ + Wyeth Lederle's Meningitec™

Primary Outcome Measures

Name	Time	Method
One month after the third dose of the primary vaccination course, measurement of serum bactericidal titers against meningococcal serogroups A and C (SBA-MenA; SBA-MenC) and anti-PRP antibody concentration.

Secondary Outcome Measures

Name	Time	Method
Immunogenicity: Before the first dose, antibody concentrations or titres against vaccine antigens (MenA, MenC, PRP, pertussis)
One month after the third dose, antibody concentrations or titres against all vaccine antigens
Reactogenicity & safety: after each dose: solicited (d 0-7, local & general) & unsolicited (d 0-30) symptoms
Over the full course of the study: serious adverse events (SAEs)
