E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |

|
E.1.1.2 | Therapeutic area | Diseases [C] - Bacterial Infections and Mycoses [C01] |
MedDRA Classification |
E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Immune responses to MenACWY, when given: (a) concomitantly with Tdap and HPV; and (b) when given one month after Tdap, were not inferior to the immune response when MenACWY was administered alone;
• Immune response to Tdap, when given concomitantly with MenACWY and HPV, was not inferior to immune response when Tdap was administered alone |
|
E.2.2 | Secondary objectives of the trial |
a.To demonstrate that the immune response to HPV vaccine given concomitantly with MenACWY and Tdap is not inferior to the response when HPV is given alone.
b. To demonstrate that the immune response to Tdap administered alone one month after MenACWY is not inferior to the immune response to Tdap administered alone one month prior to MenACWY
c. To assess the immunogenicity of MenACWY as measured by hSBA geometric mean titers (GMTs) and by the percentage of subjects with hSBA≥1:4 and hSBA ≥ 1:8, directed against N. meningitidis serogroups A, C, W and Y.
d. To assess the immunogenicity of Tdap administered alone or concomitant with MenACWY and HPV as measured by anti-diphtheria and anti-tetanus GMCs and the percentage of subjects with a four-fold rise in antibody over baseline for anti-PT, anti- FHA, and anti-PRN titer
Safety: Describe and compare the safety profile of MenACWY in 3 study groups, and the safety profile of the HPV vaccine when given alone or with Tdap and MenACWY.
