Clinical Trial Summary

This study is to confirm non-inferiority of the three MenACWY vaccines (Menveo, Menactra or Nimenrix) in adolescents, and to identify whether the number of previous doses of MenC influences the response to the MenACWY vaccine.


Description:

Participants will be randomized to receive one of the three doses of licensed MenACWY as a booster dose in adolescents. Serology will be collect at 3 time points; prior to the booster dose and 1 month and 1 year post-vaccination to measure antibody levels. The participants are healthy students in grades 7-9 who have not received their MenACWY vaccine yet and received their routine infant MenC vaccines per previous Canadian schedules.

Eligibility INCLUSION CRITERIA All the following need to be fulfilled: 1. Healthy adolescent 2. Previous receipt of appropriate MenC vaccine according to the relevant provincial schedule (see above) 3. Parent/legal guardian has given informed consent OR participant has given consent (if participant demonstrates capacity to consent) 4. Participant has given consent (as above) OR assent. EXCLUSION CRITERIA The participant may not enter the trial if ANY of the following apply: 1. Has already received any doses of MenACWY vaccine at any age 2. Previous confirmed or suspected meningococcal disease 3. Close contact with an individual with laboratory-confirmed N. meningitidis in prior 12 months 4. Previous allergic reaction to a component of any of the 3 vaccines 5. Serious chronic or progressive disease 6. Confirmed/suspected immunodeficiency 7. Receipt of more than 1 week of immunosuppressants or immune modifying drugs (e.g. oral prednisolone >0.5mL/kg/day or intravenous glucocorticoid steroid). Nasal, topical or inhaled steroids are allowed 8. Administration of immunoglobulins within the prior 12 months and/or any blood products planned during the study period 9. Pregnancy (based on history from adolescent and parent/legal guardian) 10. Any other significant disease or disorder which, in the opinion of the Investigator, may either put the participants at risk because of participation in the trial, or may influence the result of the trial, or the participant's ability to participate in the trial. TEMPORARY EXCLUSION CRITERIA If the adolescent has a temperature = 38°C, then vaccination (and blood sampling if due to occur at same visit) will be postponed until resolution of fever.

Outcome

Type Measure Description Time frame Safety issue
Primary Confirm non-inferiority of MenC protection at 1-year post-MenACWY booster between groups with differing priming schedules N. meningitidis capsular group C serum bactericidal antibody titer 1 year following MenACWY adolescent booster
Primary Confirm non-inferiority of MenC protection at 1-year post-MenACWY booster between differing vaccines N. meningitidis capsular group C serum bactericidal antibody titer 1 year following MenACWY adolescent booster
Secondary Confirm non-inferiority of MenC protection at 1 month post-MenACWY booster between groups with differing MenC priming schedules. N. meningitidis capsular group C serum bactericidal antibody titer 1 month following MenACWY booster
Secondary Confirm non-inferiority of MenC protection at 1 month post-MenACWY booster between groups with different MenACWY vaccines N. meningitidis capsular group C serum bactericidal antibody titer 1 month following MenACWY booster
Secondary Subgroup analysis to determine effects of different MenACWY vaccines in subjects primed with different MenC schedules at 1 month and 1 year post-MenACWY booster N. meningitidis capsular group C serum bactericidal antibody titer 1 month and 1 year following MenACWY booster
Secondary Subgroup analysis to determine effects of different MenC priming schedules in subjects receiving different MenACWY booster immunizations at 1 month and 1 year post-MenACWY booster N. meningitidis capsular group C serum bactericidal antibody titer 1 month and 1 year following MenACWY booster
Secondary Confirm safety of MenACWY conjugate vaccines Adverse events as reported by study participants Up to 1 month post-vaccine
