Brief Summary:
The primary purpose of this study is to evaluate the persistence of bactericidal antibodies in children of approximately 22 to 45 months of age previously enrolled in the V59P22 study (NCT00667602) who received Novartis MenACWY Conjugate Vaccine or Meningococcal C Conjugate Vaccine. This is measured by percentage of subjects with human Serum Bactericidal Assay (hSBA) titers ≥ 1:8 directed against Neisseria meningitidis serogroups A, C, W-135, and Y. In addition the response one month post an additional dose of Novartis MenACWY will be measured by percentage of subjects with hSBA titers ≥ 1:8 and GMTs.

Arm Intervention/treatment
Experimental: MenACWY (2 primary + 1 booster dose)
Subjects who had previously received two primary doses of MenACWY-CRM vaccine (at 6-8 months and 12 months of age) in parent study, were administered one booster dose of the same vaccine in this extension study.
 Biological: MenACWY-CRM
Experimental: MenACWY (1 primary + 1 booster dose)
Subjects who had previously received one primary dose of MenACWY-CRM vaccine (at 12 months of age) in parent study, were administered one booster dose of the same vaccine in this extension study.
 Biological: MenACWY-CRM
Experimental: MenC (1 primary dose)+MenACWY (1 booster dose)
Subjects who had previously received one primary dose of the comparator MenC vaccine (at 12 months of age) in parent study, were administered one booster dose MenACWY-CRM vaccine in this extension study.
 Biological: MenACWY-CRM


Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Percentage of Subjects With Persisting Serum Bactericidal Antibody Titers ≥1:8, Upto 13-33 Months After Primary Vaccination With Either MenACWY-CRM or MenC Vaccine [ Time Frame: From 13-33 months post last vaccination in parent study (V59P22) ]

    The percentage of subjects with persisting serum bactericidal antibody (hSBA)titers ≥1:8 against Neisseria meningitidis serogroups A,C,W,Y, 13-33 months after receiving either one or two doses of MenACWY-CRM conjugate vaccine or one dose of MenC vaccine in parent study, is reported.

    The functional bactericidal antibodies response against N. meningitidis serogroups was measured with the serum bactericidal assay using human complement (hSBA)


  2. Percentage of Subjects With Serum Bactericidal Antibody Titers ≥1:8, One Month After MenACWY-CRM Booster Vaccination [ Time Frame: 1 month post booster ]
    The serum antibody response following a booster dose of MenACWY-CRM conjugate vaccine in children, who had previously received either one or two doses of the same vaccine in the parent study, is reported as percentage of subjects with hSBA titers ≥1:8 against N. meningitidis serogroups A,C,W,Y.

  3. Geometric Mean Titers in Children,One Month After MenACWY-CRM Booster Vaccination [ Time Frame: 1 month post booster vaccination ]
    The serum antibody titers following a booster dose of MenACWY-CRM conjugate vaccine in children, who had previously received either one or two doses of the same vaccine in the parent study, are reported as geometric mean titers (GMTs) against N. meningitidis serogroups A,C, W,Y.

  4. Percentage of Subjects (Who Had Previously Received MenC Vaccine) With Serum Bactericidal Antibody Titers ≥ 1:8, After One Dose of MenACWY-CRM Vaccination [ Time Frame: 1 month after vaccination ]
    The serum antibody response following a dose of MenACWY-CRM conjugate vaccine in children, who had previously received one dose of MenC vaccine in the parent study, is reported as percentage of subjects with hSBA titers ≥1:8 against N. meningitidis serogroups A,C, W,Y

  5. Geometric Mean Titers in Children (Who Previously Received MenC Vaccine) One Month After One Dose of MenACWY-CRM Vaccine [ Time Frame: 1 month post vaccination ]
    The serum antibody titers following one dose of MenACWY-CRM conjugate vaccine in children, who had previously received one dose of MenC vaccine in the parent study, are reported as GMTs against N. meningitidis serogroups A,C,W,Y


Secondary Outcome Measures :
  1. Persisting Geometric Mean Titers in Children, 13-33 Months After Primary Vaccination With Either MenACWY-CRM or MenC Vaccine [ Time Frame: From 13-33 months post last vaccination in parent study (V59P22) ]
    The persisting serum bactericidal antibody titers in children, 13-33 months after receiving either one or two doses of MenACWY-CRM vaccine or one dose of Men C vaccine in the parent study, are reported as GMTs against N. meningitidis serogroups A,C, W,Y

  2. Percentage of Subjects With Serum Bactericidal Titers ≥1:8, Who Previously Received 1 Primary Dose of Either MenACWY-CRM or Men C Vaccine [ Time Frame: 1 month post vaccination ]
    Comparison of serum antibody responses following one dose of MenACWY-CRM conjugate vaccine in children, who had previously received either one dose of the same vaccine or one dose of Men C vaccine in the parent study, is reported as percentage of subjects with hSBA titers ≥1:8 against N. meningitidis serogroups A,C,W,Y

  3. Geometric Mean Titers Following One Dose of MenACWY-CRM Vaccine in Children Who Previously Received 1 Primary Dose of Either MenACWY-CRM or Men C Vaccine [ Time Frame: 1 month post vaccination ]
    Comparison of serum antibody titers following a one dose of MenACWY-CRM conjugate vaccine in children, who had previously received either one dose of the same vaccine or one dose of MenC vaccine in the parent study, are reported as GMTs against N. meningitidis serogroups A,C, W,Y

  4. Number of Children Reporting Solicited Local and Systemic Adverse Events (AEs) After MenACWY-CRM Vaccination [ Time Frame: Day 1-7 after vaccination ]
    The safety and tolerability of MenACWY-CRM vaccine in children (who had previously received either one or two doses of MenACWY-CRM vaccine or one dose of MenC vaccine in the parent study) is assessed in terms of number of subjects reporting solicited local and systemic AEs after MenACWY-CRM vaccine.

  5. Number of Children Reporting Unsolicited Adverse Events After MenACWY-CRM Vaccination [ Time Frame: Day 1-28 after vaccination ]
    The safety of MenACWY-CRM vaccine in children (who had previously received either one or two doses of MenACWY-CRM vaccine or one dose of MenC vaccine in the parent study) is assessed in terms of number of subjects reporting any unsolicited AEs (day 1 to day 7); serious AEs and AEs necessitating medical attention/or premature withdrawal (day 1 to day 28) after MenACWY-CRM vaccine.
