Immunogenicity and Safety of an Investigational Quadrivalent Meningococcal Conjugate Vaccine Versus Nimenrix® or NeisVac-C® in Healthy Toddlers 12 to 23 Months of Age

Sanofi Pasteur, a Sanofi Company·interventional·Posted Mar 26, 2019·Updated Sep 15, 2025

In Brief

A Phase 3 clinical trial evaluating Meningococcal polysaccharide (serogroups A, C, Y, and W) tetanus toxoid Conjugate vaccine, Meningococcal polysaccharide group A, C, W-135 and Y Conjugate vaccine, and 1 other intervention for Meningococcal Immunisation (Healthy Volunteers). Completed, enrolled 707 participants across 29 sites in 3 countries.

Detailed Summary

Primary Objective: To demonstrate: * the non-inferiority of the seroprotection rate (antibody titers greater than or equal to \[\>=\] 1:8) to meningococcal serogroup C following the administration of MenACYW Conjugate or Nimenrix® as measured by serum bactericidal assay using human complement (hSBA). If this non-inferiority was demonstrated, then * the non-inferiority of the antibody response (geometric mean titers \[GMT\]). If this non-inferiority was demonstrated, then * the superiority of the antibody response (GMT). If this superiority was demonstrated, then * the superiority of the seroprotection rate. Or to demonstrate: * the non-inferiority of the seroprotection rate (antibody titers \>= 1:8) to meningococcal serogroup C following the administration of MenACYW Conjugate or NeisVac-C® as measured by serum bactericidal assay using baby rabbit complement (rSBA). If this non-inferiority was demonstrated, then * the non-inferiority of the antibody response (GMT). If this non-inferiority was demonstrated, then * the superiority of the antibody response (GMT). Secondary Objective: To demonstrate: * the non-inferiority of the seroprotection rate (antibody titers \>= 1:8) to meningococcal serogroup C following the administration of MenACYW Conjugate vaccine or Nimenrix® as measured by rSBA. If this non-inferiority was demonstrated, then * the non-inferiority of the antibody response (GMT). If this non-inferiority was demonstrated, then * the superiority of the antibody response (GMT). Or to demonstrate: * the non-inferiority of the seroprotection rate (antibody titers \>= 1:8) to meningococcal serogroup C following the administration of MenACYW Conjugate vaccine or NeisVac-C® as measured by hSBA. If this non-inferiority was demonstrated, then * the non-inferiority of the antibody response (GMT). If this non-inferiority was demonstrated, then * the superiority of the antibody response (GMT) .
