Trial overview

Official title: A Phase 2b, Controlled, Observer-Blind, Multi-Center Study Assessing the Effectiveness, Immunogenicity and Safety of the 3rd Dose of Novartis Meningococcal ABCWY Vaccine Administered to Healthy Adolescents in the U.S.
Trial description: This is extension of the V102_16 study (NCT02140762). V102_16E1 is designed to assess the effectiveness of a 3-dose vaccination series of MenABCWY, administered according to 0, 2, 6 month schedule, against the same panel of endemic US N. meningitidis serogroup B strains, as measured by enc-hSBA assay. The subjects who completed the parent V102_16 study will be invited at the time of their last study visit to participate in this extension study.
Primary purpose:
Prevention
Trial design:
Parallel Assignment
Masking:
Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Allocation:
Randomized
Primary outcomes:

Percentages of subjects without bactericidal activity at 1:4 dilution against each US Neisseria meningitides (N. meningitidis) serogroup B strain at 1 month after the 3-dose vaccination series.

Timeframe: At Month 7 (1 month after the 3-dose vaccination series)

Secondary outcomes:

Percentages of subjects without bactericidal activity at 1:4 dilution against each US N. meningitidis serogroup B strain at 4 months after the 3-dose vaccination series.

Timeframe: At Month 10 (4 months after the 3-dose vaccination series)

Timeframe: At Months 7 and 10 (1 and 4 months after the 3-dose vaccination series)

Percentages of subjects with a three-fold rise in HT-hSBA titers against the N. meningitidis serogroup B test strains at 1 and 4 months after the 3-dose vaccination series.

Timeframe: At months 7 and 10 (1 and 4 months after 3-dose vaccination series)

Percentages of subjects with a four-fold rise in HT-hSBA titers against the N. meningitidis serogroup B test strains at 1 and 4 months after the 3-dose vaccination series.
