E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Meningococcus group B disease, which can cause a variety of symptoms. The most serious of these are meningitis, and septicaemia (also known as blood poisoning). |
|
E.1.1.1 | Medical condition in easily understood language |
|
E.1.1.2 | Therapeutic area | Diseases [C] - Bacterial Infections and Mycoses [C01] |
MedDRA Classification |
E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To determine if giving one booster dose of a licensed vaccine (4CMenB) to protect against meningococcal group B disease produces an antibody response that is protective in teenagers who were immunised as infants, as opposed to the two doses that are required for adolescents who have never been vaccinated before. |
|
E.2.2 | Secondary objectives of the trial |
To investigate the persistence of the protective antibody response in adolescents who were vaccinated against meningococcal group B disease as infants, and those who were vaccinated as an infant with a toddler booster vaccine.
We will also explore: -the quantity and qualities of the responses to the vaccine including if the immune system keeps a memory of having encountered the vaccine, in adolescents after infant vaccination, after infant vaccination with toddler boosting, and after adolescent vaccination. - the impact of the vaccine on fever and other possible vaccine side effects in adolescents - if a giving a booster dose of the vaccine is more likely to result in expected vaccine side effects |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
For recruitment to all study groups: • Parents/legal guardians are willing and able to comply with the requirements of the trial protocol and have internet access for the duration of the study. • Parents/legal guardians have given informed consent for their child’s participation in the study • Participant is willing and able to give informed assent for participation in the trial. • In the Investigator’s opinion, participants are able and willing to comply with all trial requirements. • Parents/legal guardians/participants are willing to allow their General Practitioner and consultant, if appropriate, to be notified of participation in the trial.
For recruitment to study groups 1 to 6 only • Male or Female, aged approximately 11 years who have completed a vaccination course of meningitis B vaccine as an infant or toddler in a previous clinical trial conducted by OVG.
For recruitment to Naïve groups 7 and 8 only • Male or Female, born between 25/06/2006 - 17/12/2006 who have not previously received meningitis vaccine

E.4 | Principal exclusion criteria |
The participant may not enter the trial if ANY of the following apply: • Children of parents/legal guardians who are on the delegation log for this study • History of invasive meningococcal B disease • History of being a household contact with a case of confirmed bacterial meningitis • Confirmed or suspected immunodeficiency • A family history of congenital or hereditary immunodeficiency, or maternal HIV • Current 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. • History of anaphylactic reaction to any component of the vaccine • No internet access for the duration of the study. • 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. • Participants who have participated in another research trial involving an investigational product in the past 12 weeks. • Prior or planned receipt of any other investigational vaccine or drug. • Thrombocytopenia or any bleeding disorder. • Receipt of blood, blood products, or plasma derivatives within the past 3 months Exclusion to study groups 1 to 6 only • Any previous vaccination with 4CMenB vaccine except as part of V72P6, V72P6E1, V72P9 or V72P9E1 clinical trials. • Any previous vaccination with another meningococcal B vaccine (such as outer membrane vesicle vaccines) • Receipt of immunosuppressive therapy such as anti-cancer chemotherapy or radiation therapy within the preceding 1 month or long-term systemic corticosteroid therapy (e.g. oral prednisolone >0.5ml/kg/day or intravenous glucocorticoid steroid). However, this may be discussed on a case-by-case basis. Nasal, topical or inhaled steroids are allowed.
Exclusion to Naïve groups 7 and 8 only • Previous vaccination with 4CMenB vaccine or with any other meningococcal B vaccine (such as outer membrane vesicle vaccines) • Receipt of immunosuppressive therapy such as anti-cancer chemotherapy or radiation therapy. • Current receipt of long-term systemic corticosteroid therapy (e.g. oral prednisolone >0.5ml/kg/day or intravenous glucocorticoid steroid). Nasal, topical or inhaled steroids are allowed. • Long term prophylactic antibiotic use
