Study to Evaluate the Immune Response After a Booster Dose of a Quadrivalent Meningococcal (MenACYW) Conjugate Vaccine When Administered Alone or Concomitantly With a Licensed Meningococcal Serogroup B Vaccine, in Participants Who Received Primary Quadrivalent Meningococcal Conjugate Vaccine (MCV4)
- Conditions
- Meningococcal Immunisation (Healthy Volunteers)
- Registration Number
- NCT04084769
- Lead Sponsor
- Sanofi Pasteur, a Sanofi Company
- Brief Summary
Primary Objective:
To demonstrate the vaccine seroresponse sufficiency of meningococcal serogroups A, C, Y, and W following the administration of a booster dose of meningococcal Polysaccharide (Serogroups A, C, Y and W) Tetanus Toxoid (MenACYW) Conjugate vaccine:
* In Group 1 participants who were first vaccinated with 1 dose of MenACYW Conjugate vaccine 3-6 years before the booster dose.
* In Group 2 participants who were first vaccinated with 1 dose of Menveo vaccine (meningococcal \[Groups A, C, Y and W135\] Oligosaccharide Diphtheria CRM197 Conjugate vaccine) 3-6 years before the booster dose.
Secondary Objective:
To describe:
* The vaccine seroresponse, seroprotection (serum bactericidal assay using human complement \[hSBA\] titer greater than or equal to \[\>=\]1:8), and antibody responses (geometric mean titers \[GMTs\]) of meningococcal serogroups A, C, Y, and W measured using hSBA in serum specimens collected 6 days (±1 day) after vaccination in a subset of 50 participants per group (Groups 1 and 2).
* The vaccine seroresponse, seroprotection (hSBA titer \>=1:8), and antibody responses (GMTs) to serogroups A, C, Y, and W measured using hSBA on Day (D)0 (pre-vaccination) and D30 (+14 days) after vaccination with MenACYW Conjugate vaccine alone (Groups 1 and 2).
* The antibody persistence (GMTs and vaccine seroprotection; hSBA titer \>=1:8) of meningococcal serogroups A, C, Y, and W before a booster dose in participants who received either MenACYW Conjugate vaccine or Menveo vaccine 3-6 years earlier.
* The antibody persistence (GMTs and vaccine seroprotection; hSBA titer \>=1:8) of meningococcal serogroups A, C, Y, and W in participants who received either a single dose MenACYW Conjugate vaccine (participants randomized to MET59 Groups 1, 3, and 4) or Menveo vaccine (participants assigned to MET59 Group 2), as part of study MET50, or MET43 (participants randomized to MET59 Groups 1, 3 and 4).
* To describe the vaccine seroresponse, seroprotection (hSBA titer \>=1:8), and antibody responses (GMTs) to the antigens present in MenACYW Conjugate vaccine, when MenACYW Conjugate vaccine was given concomitantly with meningococcal serogroup B (MenB) vaccine (Groups 3 and 4), compared to those when it was given alone (Group 1).
- Detailed Description
Study duration per participant was approximately 6 months including: 1 day of screening and vaccination, 1 or 2 additional visits at Day 6 and Day 30, 2 phone calls and a safety follow-up/end of study visit, at Day 8 and Day 180 after vaccine administration, respectively.
Safety assessment included solicited reactions within 7 days after vaccination, unsolicited adverse events (AEs) up to 30 days after vaccination, serious adverse events (SAEs) throughout the study.

Name Time Method Percentage of Participants With Vaccine Seroresponse Against Meningococcal Serogroups A, C, Y, and W Following Vaccination With MenACYW Conjugate Vaccine in Study MET59: Group 2 Day 30 (post-vaccination) in study MET59 Antibody titers against meningococcal serogroups A, C, Y, and W were measured by hSBA. The hSBA vaccine seroresponse was defined as a post-vaccination hSBA titer \>=1:16 for participants with pre-vaccination hSBA titer \<1:8, or a \>=4-fold increase in hSBA titer from pre-vaccination to post-vaccination for participants with pre-vaccination hSBA titer \>=1:8. Immune response was considered sufficient if lower limit of the 1-sided 97.5% CI for percentage of participants with hSBA seroresponse against serogroups A, C, Y and W was greater than 75%.
Percentage of Participants With Vaccine Seroresponse Against Meningococcal Serogroups A, C, Y, and W Following Vaccination With MenACYW Conjugate Vaccine in Study MET59: Group 1 Day 30 (post-vaccination) in study MET59 Antibody titers against meningococcal serogroups A, C, Y, and W were measured by Serum Bactericidal Assay Using Human Complement (hSBA). The hSBA vaccine seroresponse was defined as a post-vaccination hSBA titer greater than or equal to (\>=) 1:16 for participants with pre-vaccination hSBA titer less than (\<) 1:8, or a \>= 4-fold increase in hSBA titer from pre-vaccination to post-vaccination for participants with pre-vaccination hSBA titer \>= 1:8. Immune response was considered sufficient if lower limit of the 1-sided 97.5% CI for percentage of participants with hSBA seroresponse against serogroups A, C, Y and W was greater than 75%.
