E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
- To evaluate the safety and reactogenicity of both vaccines in HIV+ subjects for up to one month after the third dose of vaccine.
- To demonstrate non-inferiority of Cervarix versus (vs.) Gardasil in terms of geometric mean titers (GMTs) against HPV-16 and HPV-18 measured by Pseudovirion-based neutralization assay (PBNA) one month after administration of the third dose of vaccine in HIV+ subjects.
- If the first primary objective for immunogenicity is demonstrated, superiority of Cervarix over Gardasil in terms of GMTs against HPV-16 and HPV-18 measured by PBNA in HIV+ subjects will be assessed following a sequential approach.
- First, superiority for HPV-18 will be assessed.
- Second, if superiority for HPV-18 is shown, superiority for HPV-16 will be assessed. |
|
E.2.2 | Secondary objectives of the trial |
- To demonstrate superiority of Cervarix vs. Gardasil in terms of GMTs against HPV-16 or HPV-18 measured by PBNA 1 month (M) after the administration of the 3rd dose of vaccine in HIV- subjects.
- To evaluate the antibody response of both vaccines with respect to HPV-16 and HPV-18 antibody levels by ELISA at Day 0, Week (W)6, W 10, M 7, 12, 18 and 24 in all subjects.
- To evaluate antibody response, by ELISA, against HPV-16 and HPV-18 in CVS at Day 0, W 6, W 10, M 7, 12 and 24 in post-menarcheal subjects who volunteer for this procedure.
- To evaluate memory B and T cell-mediated immune (CMI) response against HPV-16 and HPV-18 at Day 0, W 6, W 10, M 7 and 12 in a subset of approximately 100 subjects (50 HIV+ and 50 HIV-).
- To evaluate the safety and reactogenicity of both vaccines in HIV- subjects for up to 1M after the 3rd dose of vaccine and in all subjects for up to 24 M after the Iast vaccine dose. |
