E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
1. To evaluate the persistence of the antibody response at 5 years after one dose of MenACWY or Menomune, as measured by the percentage of subjects with bactericidal activity using human complement (hSBA) ≥1:8 directed against N. meningitidis serogroups A, C, W-135, and Y.
2. To evaluate the antibody response to one dose of MenACWY in subjects who had previously received one dose of MenACWY compared to the antibody response to one dose of MenACWY in meningococcal vaccine-naïve subjects, as measured by hSBA geometric mean titers (GMTs) directed against N. meningitidis serogroups A, C, W-135 and Y, at 28 days after vaccination. |
|
E.2.2 | Secondary objectives of the trial |
1. To evaluate the persistence of the antibody response at 5 years after one dose of MenACWY or Menomune, as measured by hSBA GMTs and percentage of subjects with hSBA ≥1:4 directed against N. meningitidis serogroups A, C, W-135, and Y.
2. To evaluate the antibody response to one dose of MenACWY in subjects who had previously received one dose of MenACWY compared to the antibody response to one dose of MenACWY in meningococcal vaccine-naïve subjects, as measured by percentage of subjects with seroresponse and percentage of subjects with hSBA ≥1:8 and hSBA ≥1:4 directed against N. meningitidis serogroups A, C, W-135, and Y, at 28 days after vaccination.
3. To evaluate all remaining pairwise immunogenicity comparisons (as expressed as hSBA ≥1:4 and ≥1:8 and GMTs) between each of the three study groups at days 1, 7, and 28 after vaccination.
Safety Objectives
To assess the safety and tolerability of one dose of MenACWY in all study subjects. |
