  Purpose

This is a clinical study to assess the safety, tolerance and immunogenic response to MCV4(quadrivalent meningococcal polysaccharide conjugate, meningococcal serogroups A,C,Y, and W135), Tdap (diphtheria, tetanus, and acellular pertussis), and bivalent rLP2086 vaccine. Healthy male and female subjects, between the ages of 10 to 12 years old, will be randomized into 1 of 3 groups. The subjects, investigators, site staff and sponsor will be blinded to all injections given throughout the study. An unblinded administrator will be responsible to administer the vaccinations to all subjects and will be unblinded to the subject randomization in order to determine which subjects were in randomized to group 3 so they may receive their catch-up vaccinations of MCV4 and Tdap. A final telephone contact will be conducted with all subjects 6-months post their last vaccination to obtain safety information.

Primary Outcome Measures:
  • The geometric mean titers (GMTs) or geometric mean concentrations (GMCs) for each of the antibodies reactive with each of the 10 antigenic components in the marketed vaccines at visit 2, among subjects in Groups 1 and 2. [ Time Frame: Month 1 ] [ Designated as safety issue: No ]
  • The hSBA geometric mean titers (GMTs) for each of the 2 primary strains (PMB80 [A22] and PMB2948 [B24]) at visit 6, among subjects in Groups 1 and 3. [ Time Frame: Month 7 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • The seroresponse rate at visit 2 for each of the 10 marketed vaccine antigens in Group 1 and Group 2. [ Time Frame: Month 1 ] [ Designated as safety issue: No ]
  • Proportion of subjects (Groups 1 and 2) who achieve an antibody level >=1.0 IU/mL to tetanus and proportion of subjects (Groups 1 and 2) who achieve an antibody level >1.0 IU/mL to diphtheria toxoid. [ Time Frame: Month 1 ] [ Designated as safety issue: No ]
  • hSBA titers as measured by GMTs for each of the 2 primary MnB test strains (PMB80 [A22] and PMB2948 [B24]) at each applicable blood sampling time point. [ Time Frame: Month 0, 1, 3, 7 ] [ Designated as safety issue: No ]
  • Proportion of subjects with hSBA titers ≥LLOQ, ≥1:4, ≥1:8, ≥1:16 , ≥1:32, ≥1:64, ≥1:128 at each blood draw visit, for each of the 2 primary strains (PMB80 [A22] and PMB2948 [B24]). [ Time Frame: Month 0, 1, 3, 7 ] [ Designated as safety issue: No ]
  • Exploratory immunogenicity endpoints will be applied to MCV4 antigenic components in subjects from Group 1 and Group 2. The exploratory endpoints are IgG response (measured as GMCs) in serogroups A, C, Y and W-135. [ Time Frame: Month 1 ] [ Designated as safety issue: No ]
  • Proportion of subjects achieving at least a 4-fold increase in hSBA titer from baseline to 1-month after the second and the third vaccination with the bivalent rLP2086 vaccine for each of the 2 primary strains (PMB80 [A22], PMB2948 [B24]). [ Time Frame: Month 3, 7 ] [ Designated as safety issue: No ]
  • Safety measured by subjects reporting adverse events and use of antipyretic medication. [ Time Frame: Throughout the study. ] [ Designated as safety issue: Yes ]
