Geometric Mean Titers (GMTs) of Meningococcal Serogroups A, C, Y, And W Antibodies Following Vaccination With 3 Lots of MenACYW Conjugate Vaccine (Day 30 (post-vaccination)) (del registro, en inglés)
Cómo lo describe el promotor
En el documentoEn inglés, del registroThe purpose of the study was to evaluate immune lot consistency of Meningococcal Polysaccharide (Serogroups A, C, Y and W) Tetanus Toxoid (MenACYW) Conjugate vaccine and the immune non-inferiority compared to the licensed vaccine Menactra®, and describe the safety and additional immunogenicity of these study vaccines in adolescents and adults 10 to 55 years of age in the United States (US). Primary Objectives: * To demonstrate the immune lot consistency of the antibody responses to meningococcal serogroups A, C, Y, and W following the administration of a single dose of MenACYW Conjugate vaccine with respect to serum bactericidal assay using human complement (hSBA) geometric mean titers (GMTs). * To demonstrate the non-inferiority of the antibody responses to meningococcal serogroups A, C, Y, and W following the administration of a single dose of MenACYW Conjugate vaccine (pooled Lots 1 to 3) compared to those observed following the administration of a single dose of Menactra®. Secondary Objective: * To demonstrate the non-inferiority of the antibody responses to meningococcal serogroups A, C, Y, and W following the administration of a single dose of MenACYW Conjugate vaccine (pooled Lots 1 to 3) compared to those observed following the administration of a single dose of Menactra® in the adult population (18 to 55 years old). * To demonstrate the non-inferiority of the antibody responses to meningococcal serogroups A, C, Y, and W following the administration of a single dose of MenACYW Conjugate vaccine (pooled Lots 1 to 3) compared to those observed following the administration of a single dose of Menactra® in the adolescent population (10 to 17 years old). * To compare the hSBA vaccine seroresponses of meningococcal serogroups A, C, Y, and W for each of 3 lots of MenACYW Conjugate vaccine 30 days (+14 days) after vaccination. * To compare the hSBA antibody GMTs of meningococcal serogroups A, C, Y, and W following the administration of MenACYW Conjugate vaccine to those observed following the administration of Menactra®. Observational Objectives: * To describe the safety profile of MenACYW Conjugate vaccine and that of the licensed Menactra®.
