Study to Assess Immunegnicity & Safety of Pentavalent Meningococcal Vaccine (NmCV-5)
Mali, The Gambia1,800 participantsStarted 2019-08-20
Plain-language summary
This observer-blind, randomized, active controlled trial will be conducted among 2-29 year olds in two sites (Mali and The Gambia). The objectives of the study are to assess and compare the immunogenicity and safety of NmCV-5 with that of Menactra.
A total of 1800 eligible participants (who or their parents/guardians have given written informed consent) will be randomised 2:1 (NmCV-5: Menactra) in each of the three age strata 18-29 years, 11-17 years \& 2-10 years (400 NmCV-5 recipients \& 200 Menactra recipients in each age strata).
Each subject will receive a single dose of study vaccine and will be followed up for 6 months post vaccination during which solicited reactions (for seven days), unsolicited AEs (28 days) and SAEs (until the end of study i.e. 168 days after vaccination) will be collected. A blood sample will be collected at baseline (pre-vaccination) and at day 28 post-vaccination for immunogenicity assessment by a Serum Bactericidal Activity assay using rabbit complement (rSBA).

. Male or non-pregnant female 2 through 29 years of age, inclusive, at the time of study IP administration.
. Written informed consent obtained from subjects at least 18 years of age or from their parent/guardian for subjects less than 18 years of age with additional subject assent obtained as appropriate for participating community (i.e. subjects at least 13 years of age in Mali or at least 12 years of age in The Gambia).

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
. Acute illness, at the time of study IP administration (once acute illness is resolved, if appropriate, as per investigator assessment, subject may be re-revaluated for eligibility).
. Recorded fever (for eligibility purpose defined as a body temperature greater than 37.5°C) within 3 days prior to study IP administration (once fever/acute illness is resolved, if appropriate, as per investigator assessment, subject may be re-revaluated for eligibility).
. Previous immunization with a Neisseria meningitidis vaccine other than MenAfriVac® during the previous five years.
. Current or previous, confirmed disease caused by Neisseria meningitidis.
. Household contact with or intimate exposure to an individual with any laboratory confirmed Neisseria meningitidis infection within 90 days prior to study IP administration.
. Known hypersensitivity to any component of the study IPs (i.e., NmCV-5 or Menactra®).
. History of significant hypersensitivity reactions to any previous vaccine.
. Administration of any vaccine other than study IPs within 28 days prior to study IP administration or planned administration prior to completion of the study Day 29 visit.
