E.1.1 | Medical condition(s) being investigated |
Prevention of meningococcal disease caused by serogroup C Neisseria meningitidis by evaluating the immunogenicity, tolerability, and safety of a liquid formulation of Novartis meningococcal C conjugate vaccine (MenC-CRM liquid) and of the lyophilized MenC-CRM vaccine produced with drug substance manufactured at Rosia, Italy, in comparison to the lyophilized MenC-CRM vaccine produced with drug substance manufactured at Emeryville, USA (Menjugate Kit). |

E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The equivalence of MenC-CRM liquid to Menjugate Kit and the equivalence of MenC-CRM ROS to Menjugate Kit will be simultaneously assessed with adjustment for multiple comparisons.
1. To demonstrate the equivalence of MenC-CRM liquid to Menjugate Kit when administered to toddlers, as measured by human serum bactericidal activity (hSBA) geometric mean titers (GMTs) against N. meningitidis type C, approximately 28 days after a single vaccination.
2. To demonstrate the equivalence of MenC-CRM ROS to Menjugate Kit when administered to toddlers, as measured by human serum bactericidal activity (hSBA) geometric mean titers (GMTs) against N. meningitidis type C, approximately 28 days after a single vaccination.
|
|
E.2.2 | Secondary objectives of the trial |
To demonstrate equivalence of MenC-CRM liquid to MenC-CRM ROS when administered to toddlers, as measured by the ratio of the hSBA GMTs, approximately 28 days after a single vaccination. |
|

E.3 | Principal inclusion criteria |
Subjects eligible to be enrolled in the study:
1. Healthy 12 – 23 (inclusive) month-old male or female toddlers
2. A parent/legal guardian has given written informed consent after the nature of the study has been explained.

12. Received any other vaccines within 30 days prior to enrollment or intent to receive any other vaccine during the study (Exception: Inactivated influenza vaccine may be administered up to 15 days prior to study immunization and no less than 15 days after study immunization).
13. Child's parent(s) or legal guardian(s) are not able to comprehend and to follow all required study procedures for the whole period of the study.
14. Participation in any clinical trial with another investigational product 30 days prior to first study visit or intent to participate in another clinical study during this study.
15. Family members or household members of site research staff.
16. History or any illness/condition that, in the opinion of the investigator, might interfere with the results of the study or pose additional risk to the subjects due to participation in the study.
17. Any serious chronic or progressive disease according to judgment of the investigator (neoplasm, insulin dependent diabetes, cardiac, renal or hepatic disease). |
