Trial Outcomes & Findings for A Study to Evaluate Safety and Immune Response of Novartis Meningococcal ACWY Conjugate Vaccine In US Adolescents and Adults (NCT NCT00450437)

NCT ID: NCT00450437

Last Updated: 2015-01-28

Results Overview

Immunogenicity of a single injection of Meningococcal ACWY (3 lots pooled) to that of a licensed meningococcal ACWY conjugate vaccine, defined as the percentage of subjects with seroreponse directed against N. meningitidis serogroups A, C, W, and Y (healthy subjects 19 to 55 years of Age). Seroresponse to MenACWY: For a subject with hSBA titer \<1:4 at baseline, seroresponse is defined as a postvaccination hSBA titer ≥ 1:8; for a subject with hSBA titer ≥ 1:4 at baseline, seroresponse is defined as a postvaccination hSBA titer of at least 4 times the baseline.
