Phase IIb Primary Vaccination Study to Evaluate Non-Inferiority & Persistence of the Immune Response of GSK Biologicals' MenACWY Conjugate Vaccine (Intramuscularly) vs Mencevax ACWY (Subcutaneously) to Healthy Subjects (11-55 Years of Age)
In Brief
A Phase 2 clinical trial evaluating meningococcal ACWY (vaccine) and Mencevax™ ACWY for Infections, Meningococcal. Completed, enrolled 500 participants across 3 sites in 2 countries.
Detailed Summary
Meningococcal disease is mostly caused by N. meningitidis of serogroups A, B, C, W-135, Y. Meningococcal polysaccharide-conjugate vaccines have the advantage to induce a T-cell dependant immune response while the existing polysaccharide vaccines induce a T-cell independent response, i.e. with no immune memory response. GSK Biologicals has developed a combined Men ACWY conjugate vaccine intended to protect against meningococcal disease due to serogroups A, C, W-135 and Y. In the vaccination phase of this study, the new MenACWY-TT conjugate vaccine will be evaluated in adolescents and adults using Mencevax™ ACWY as control. In the long-term follow-up phase (extension phase) of the study, the long-term protection offered by the new MenACWY-TT conjugate vaccine will be assessed up to five years after the vaccination in adolescents and adults using Mencevax™ ACWY as control. This protocol posting deals with objectives \& outcome measures of both the primary \& extension phases.
