Evaluation of Persistence of Anti-meningococcal Bactericidal Antibodies Among Adolescents Who Previously Received MenACWY Conjugate Vaccine

Phase 3
Completed
Conditions
Meningococcal Meningitis
Interventions
Biological: MenACWY-CRM conjugate vaccine
Biological: Licensed comparator
Registration Number
NCT00856297
Lead Sponsor
Novartis Vaccines
Brief Summary

The primary objective is to evaluate the persistence of bactericidal antibodies in adolescents previously enrolled in the V59P13 study who received either Novartis MenACWY Conjugate Vaccine or commercially available MenACWY conjugate vaccine. The study will also enroll age-matched subjects who have never received any other meningococcal vaccine (naïve subjects) to serve as an additional control group.

Primary Outcome Measures
NameTimeMethod
Percentages of Subjects With Human Complement Serum Bactericidal Activity (hSBA) Titers≥ 1:8, After One Dose of Either MenACWY-CRM Conjugate or Licensed Comparator Vaccine21 months, 3 years and 5 years postvaccination

Immune response of one dose of MenACWY-CRM conjugate vaccine compared to that of one dose of licensed comparator vaccine at 21 months, 3 years and 5 years after vaccination, as measured by the percentages of subjects with human complement serum bactericidal activity (hSBA) titers≥ 1:8 directed against N meningitidis serogroups A, C, W and Y.

Secondary Outcome Measures
NameTimeMethod
hSBA Geometric Mean Titers (GMT) in Subjects With No Previous Meningococcal Vaccinationday 1

Immune response of age-matched subjects with no previous meningococcal vaccination, as measured by hSBA geometric mean titers (GMTs) against N meningitidis serogroups A, C, W and Y.

Percentages of Subjects With hSBA Titers≥ 1:4 and ≥ 1:8 After a Booster Dose of MenACWY-CRM Conjugate Vaccine1 month post booster vaccination

Immune response at one month after one dose of MenACWY-CRM conjugate vaccine in subjects who had previously received one dose of MenACWY-CRM conjugate vaccine or licensed comparator vaccine, as measured by percentages of subjects with hSBA Titers≥ 1:4 and ≥ 1:8 against N meningitidis serogroups A, C, W and Y.

Number of Subjects With New Medical Diagnoses of Chronic Diseases, After One Dose of Either MenACWY-CRM Conjugate Vaccine or Licensed ComparatorDay 1 to 5 years

Safety was assessed in terms of number of subjects with new diagnoses of chronic diseases, among subjects who had previously received one dose of either MenACWY-CRM conjugate vaccine or licensed comparator vaccine.

Number of Subjects Who Reported Medically Attended Adverse Events, After One Dose of Either MenACWY-CRM Conjugate or Licensed Comparator Vaccine28 days postvaccination

Safety was assessed in terms of number of subjects with medically attended AEs within 28 days after vaccination with one dose of either MenACWY-CRM conjugate or licensed comparator vaccine.

Percentages of Subjects With hSBA Titers≥ 1:4, After One Dose of Either MenACWY-CRM Conjugate or Licensed Comparator Vaccine21 months, 3 years and 5 years postvaccination

Immune response of one dose of MenACWY-CRM conjugate vaccine compared to that of one dose of licensed comparator vaccine at 21 months, 3 years and 5 years after vaccination, as measured by the percentages of subjects with hSBA titers≥ 1:4 against N meningitidis serogroups A, C, W and Y.

Percentages of Subjects With No Previous Meningococcal Vaccination With hSBA Titers≥ 1:4 and ≥ 1:8day 1

Immune response of age-matched naive subjects with no previous meningococcal vaccination, as measured by the percentages of subjects with hSBA titers≥ 1:4, and ≥ 1:8 against N meningitidis serogroups A, C, W and Y.

Percentages of Subjects With hSBA Titers≥ 1:4 and ≥ 1:8 in Subjects After One Dose of MenACWY-CRM Conjugate Vaccine2 years postvaccination

Persistence of immune response at two years following administration of one dose of MenACWY-CRM conjugate vaccine in subjects who previously received one dose of either MenACWY-CRM conjugate or licensed comparator vaccine, as measured by hSBA titers≥ 1:4 and ≥ 1:8 against N meningitidis serogroups A, C, W and Y.

Persistence of hSBA Geometric Mean Titers (GMTs) in Subjects After One Dose of MenACWY-CRM Conjugate Vaccine2 years postvaccination

Persistence of immune response at two years following administration of one dose of MenACWY-CRM conjugate vaccine in subjects who previously received one dose of either MenACWY-CRM conjugate or licensed comparator vaccine, as measured by hSBA GMTs against N meningitidis serogroups A, C, W and Y.

hSBA Geometric Mean Titers (GMTs), After One Dose of Either MenACWY-CRM Conjugate or Licensed Comparator Vaccine21 months, 3 years and 5 years postvaccination

Immune response of one dose of MenACWY-CRM conjugate vaccine compared to that of one dose of licensed comparator vaccine at 21 months, 3 years and 5 years after vaccination, as measured by the hSBA Geometric Mean Titers (GMTs) against N meningitidis serogroups A, C, W and Y.

Number of Subjects Reporting Solicited Local and Systemic Adverse EventsDay 1 to Day 7

Safety was assessed as the number of subjects who had previously been vaccinated in the parent study with MenACWY-CRM or licensed comparator who reported solicited local and systemic adverse events within 7 days after the administration of a booster dose of MenACWY-CRM conjugate vaccine at 3 year time point.
