Details and patient eligibility

About

The purpose of this study is to compare the persistence of 2 or 3 doses of the GSK MenABCWY vaccine, or 2 doses of GSK rMenB+OMV vaccine (Bexsero) administered to healthy adolescents at approximately 24 months after the last meningococcal vaccination in the parent study V102_15(NCT02212457), compared with baseline antibody levels in vaccine naïve subjects at similar age at enrolment.

Full description

Naive subjects will be randomized 1:1 to receive MenABCWY or rMenB+OMV at Day 1. No randomization to treatment arm for follow-on subjects is required as vaccine groups remain the same as in the parent study V102_15 (NCT02212457).

Response to a booster dose of MenABCWY vaccine will also be assessed in follow-on subjects who received 2 or 3 doses of MenABCWY (at 0.2-, 0,.6- or 0,.2,.6-month schedules) in the parent study, and will be compared with responses to a single dose of MenABCWY in naive subjects (subjects who are meningococcal vaccine-naive and of similar age to subjects enrolled from the parent study).

Response to a booster dose of GSK Meningococcal B Recombinant vaccine (rMenB+OMV) will be assessed in subjects who received 2 doses of rMenB+OMV (at 0, 2-month schedule) in the parent study, and will be compared with responses to a single dose of rMenB+OMV in naive subjects.

• Who have not received any meningococcal vaccination since birth
• Individuals who have given their written informed consent or assent after the nature of the study has been explained according to local regulatory requirements, prior to study entry. If the subject is under age 18 at the time of enrollment, the parent(s)/ legal guardian(s) of the subject should have given their written consent.
• Individuals of who the investigator believes can and will comply with the requirements of the protocol.
• Individuals in good health as determined by the outcome of medical history, physical examination and clinical judgment of the investigator.

Exclusion criteria

Follow-on Participants:

• Current or previous, confirmed or suspected disease caused by N. meningitidis, since termination from parent study.
• Household contact with and/or intimate exposure to an individual with any laboratory confirmed N. meningitidis infection within 60 days of enrollment.
• If the subject is female of childbearing potential, sexually active, and has not used any of the acceptable contraceptive methods for at least 2 months prior to study entry and for the duration of the trial.

• Any confirmed or suspected condition with impaired/altered function of immune system.
• Chronic administration of immunosuppressants or other immune-modifying drugs within three months prior to the study vaccination or planned use throughout the study period. (For corticosteroids, this means prednisone, or equivalent, ≥ 20 mg/day. Inhaled, intranasal and topical steroids are allowed).

• Clinical conditions representing a contraindication to intramuscular vaccination and/or blood draws.
• Who have received systemic antibiotic treatment within 3 days prior to any blood draw
• Any other clinical condition that, in the opinion of the investigator, might pose additional risk to the subject due to participation in the study.
