Trial overview

Official title: A Phase 3b, Randomized, Observer-Blind, Placebo-Controlled Multi-Center Study Comparing Immunogenicity, Safety and 1 Year Persistence of Antibodies after either One or Two Doses of Novartis Meningococcal ACWY Conjugate Vaccine, administered to Healthy Children 2 to 10 years of age.
Trial description: This study was designed to conduct a comparative trial to further evaluate the safety, immunogenicity and antibody persistence of two doses of Novartis MenACWY conjugate vaccine, given 2 months apart, versus one dose of Novartis MenACWY conjugate vaccine in children 2 through 10 years of age.
Primary purpose:
Prevention
Trial design:
Parallel Assignment
Masking:
Single (Outcomes Assessor)
Allocation:
Randomized
Primary outcomes:

Non-inferiority of two vaccinations versus one vaccination of MenACWY-CRM, by age cohort, as measured by the percentage of subjects with hSBA seroresponse against N. meningitidis serogroups A, C, W and Y, at 1 month after last vaccination

Timeframe: One Month After Last Vaccination ( day 86)

Superiority of two vaccinations versus one vaccination of MenACWY-CRM, by age cohort, as measured by the percentage of subjects with hSBA seroresponse against N. meningitidis serogroups A, C, W and Y, at 1 month after last vaccination

Timeframe: One Month After Last Vaccination (day 86)

Secondary outcomes:

Percentage of Subjects With hSBA Titer ≥1:8, Directed Against N. Meningitidis Serogroups A, C, W and Y At One Month After One or Two Vaccination(s) of MenACWY-CRM

Timeframe: One Month After Last Vaccination (day 86)

Geometric Mean Titers of Subjects, Directed Against N. Meningitidis Serogroups A, C, W and Y At One Month After One or Two Vaccination(s) of MenACWY-CRM

Timeframe: One Month After Last Vaccination (day 86)

Percentage of Subjects With hSBA Titer ≥1:8, Directed Against N. Meningitidis Serogroups A, C, W and Y At One Year After One or Two Vaccination(s) of MenACWY-CRM

Timeframe: One year after one vaccination or two vaccinations (day 422).

Geometric Mean Titers of Subjects, Directed Against N. Meningitidis Serogroups A, C, W and Y At One Year After One or Two Vaccination(s) of MenACWY-CRM

Timeframe: One year after one vaccination or two vaccinations (day 422).

Number of 2 to 5 Years-Old Subjects Who Reported Solicited Local and Systemic Adverse Events After Any Vaccination

Timeframe: From Days 1-7 after each vaccination

Numbers of 6 to 10 Years-Old Subjects Who Reported Solicited Local and Systemic Adverse Events After Any Vaccination

Timeframe: From Days 1-7 after each vaccination

Number of Subjects who Reported Selected AEs After Any Vaccination

Timeframe: Day 1 to Day 86

Number of Subjects Who Reported Selected AEs After Any Vaccination

Timeframe: Day 1 to Day 422
