Main objective of the trial

• To demonstrate non-inferiority of the MenACWY liquid product aged for approximately 24 months to that of MenACWY vaccine, as measured by hSBA GMTs directed against N. meningitidis serogroup A at Day 29 after a single dose vaccination. Criterion: Non-inferiority will be concluded if lower limit of the 2-sided 95% CI for ratio of hSBA GMTs against serogroup A between the MenACWY liquid vaccine aged for approximately 24 months and MenACWY vaccine is greater than 0.5. • To demonstrate non-inferiority of the MenACWY liquid vaccine aged for approximately 30 months to that of MenACWY vaccine, as measured by hSBA GMTs directed against N. meningitidis serogroup A at Day 29 after a single dose vaccination. Criterion: Non-inferiority will be concluded if lower limit of the 2-sided 95% CI for ratio of hSBA GMTs against serogroup A between the MenACWY liquid vaccine aged for approximately 30 months and the MenACWY vaccine is greater than 0.5.

Protection of trial subjects

All subjects were observed closely for at least 30 minutes following the administration of the vaccine, with appropriate medical treatment readily available in case of anaphylaxis. Vaccines were administered by qualified and trained personnel. Vaccines were administered only to eligible subjects that have no contraindications to any components of the vaccine. Safety was monitored for 6 months after vaccination.

Recruitment details

Enrollment was defined with 2 parallel groups per phase, in a 2-phase staggered design: both experimental groups subjects receiving respectively investigational vaccine aged for approximately 24 months in phase 1, and same vaccine aged for approximately 30 months in phase 2. Both comparator groups subjects receiving not aged licensed vaccine.

Screening details

Out of the 1707 subjects enrolled in the study (inclusive of phase 1 and 2), only 1690 were exposed to the vaccination. Out of the 17 subjects excluded from study, 11 were not randomized, 5 were not administered any study treatment, 1 did not sign the informed consent form.

Notes
[1] - The number of subjects reported to be in the baseline period are not the same as the worldwide number enrolled in the trial. It is expected that these numbers will be the same.
Justification: Number of subjects reported in the baseline period are the actual number of subjects who were vaccinated, as compared to the number enrolled (started) in the study.

Percentages of subjects with ≥4 fold rise in hSBA antibody titers for each of the N.meningitidis serogroups A, C,W and Y for each vaccine group and between-group differences

End point description

The percentages of subjects with a ≥ 4-fold rise in post-vaccination hSBA (at Day 29 compared to Day 1) and associated 2-sided 95% Clopper-Pearson CIs are computed by group and N. meningitidis serogroups A, C, W and Y. A 4-fold rise in the hSBA titers is defined as: - for individuals, whose pre-vaccination titers are < the LOD (limit of detection), the post-vaccination titers must be ≥ 4-fold the LOD or ≥ the LLOQ (lower limit of quantitation) whichever is greater; - for individuals whose pre-vaccination titers are ≥ the LOD and ≤ the LLOQ, the post-vaccination titers must be at least four times the LLOQ; - for individuals whose pre-vaccination titers are > the LLOQ, the post-vaccination titers must be at least four times the pre-vaccination titer.

Percentages of subjects with hSBA antibody titers ≥8 against each of the N.meningitidis serogroups A,C,W and Y for each vaccine group and between-group differences

End point description

For each vaccine group the percentage of subjects with hSBA titer ≥8 , and its associated two-sided 95% Clopper-Pearson CIs are computed for each of the N. meningitidis serogroups A, C, W and Y. Analysis is performed on the per protocol set for immunogenicity that includes subjects who received the vaccine did not have any protocol deviation leading to exclusion , who were not excluded due to other reasons defined prior to unblinding or analysis and had available immuno data for any serogroup and time point considered.

End point description

Medically attended AEs are defined as events for which the subject received medical attention defined as hospitalization, an emergency room visit, or a visit to or from medical personnel (medical doctor) for any reason. Any medically attended AE(s) is occurrence of any medically attended AE(s) regardless of intensity grade or relation to vaccination. Serious adverse event is any congenital anomaly/birth defect in the offspring of a study subject or any untoward medical occurrence that results in death or life threatening or requires hospitalization or results in disability or incapacity.
