Popis: | Summary Background This phase 3, multi-center, open-label study evaluated the immunogenicity and safety of a quadrivalent meningococcal conjugate vaccine (MenACWY-CRM, Menveo ® ; Novartis Vaccines and Diagnostics S.r.l., Siena, Italy) in healthy Indian subjects aged 2–75 years, to provide data for licensure in India. Methods A total of 180 subjects were enrolled (60 subjects 2–10 years, 60 subjects 11–18 years, and 60 subjects 19–75 years) and received one dose of MenACWY-CRM. Serum bactericidal activity with human complement (hSBA) was measured before and 1 month after vaccination. Adverse events were collected throughout the 29-day study period. Results Percentages of subjects with post-vaccination hSBA ≥8 were 72%, 95%, 94%, and 90% for serogroups A, C, W, and Y, respectively. Geometric mean titers rose 7-fold to 42-fold against the four serogroups. Similar immune responses were observed for the age subgroups 2–10 years, 11–18 years, and 19–75 years. Seroresponse rates at 1 month following vaccination were 72%, 88%, 55%, and 71% for serogroups A, C, W, and Y, respectively. The vaccine was well tolerated with no safety concerns. Conclusion A single dose of MenACWY-CRM induced a robust immune response against all four meningococcal serogroups and was well tolerated in an Indian population 2–75 years of age. |
