Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study is the first study of Sanofi's Pentavalent Meningococcal ABCYW vaccine clinical development program to be conducted in the pediatric population below 10 years of age. The aim of the study is to assess 2 formulations of the MenPenta vaccine compared to licensed meningococcal vaccines when administered alone in children (Stage 1) or concomitantly with routine pediatric vaccines in toddlers (Stage 2) and infants (Stage 3).

Study details include:

The study duration per participant will be up to 12 months for children in Stage 1 and toddlers in Stage 2 and 16 to-19 months for infants in Stage 3.

Blinding Strategy

QUADRUPLE

Participants Caregivers Investigators Outcome Assessors
Partially blinded (treatment assignment is blinded between the two investigational formulation groups, and open label between the investigation and the comparator group)

* Laboratory personnel will be blinded to the treatment assignment
* Participants, Investigators, and Site staff preparing and administering the study intervention will be unblinded between the MenPenta and comparator groups but will be blinded between the 2 MenPenta groups The Sponsor will be partially blinded. At the time of periodic data reviews, additional measures are put in place to maintain the blind of the study participants for the Sponsor staff. The data review will be conducted on the basis of blinded outputs (where data of the 2 MenPenta groups and the control group will be reviewed in aggregate, without any distinction by group). By design, the Sponsor team will have access to partially blinded data for individual participants (eg, for assessment of SAE)
