E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
•To demonstrate the non-inferiority of MenACWY-TT co-administered with Boostrix® compared to MenACWY-TT administered alone with respect to serum bactericidal assay using rabbit complement (rSBA) geometric mean titres (GMTs) for serogroups A, C, W-135 and Y one month after MenACWY-TT vaccination.
•To demonstrate the non-inferiority of Boostrix® co-administered with MenACWY-TT compared to Boostrix® administered alone in terms of anti-diphtheria toxoid (anti-D) and anti-tetanus toxoid (anti-T) antibody concentrations one month after Boostrix® vaccination.
•To demonstrate the non-inferiority of Boostrix® co-administered with MenACWY-TT compared to Boostrix® administered alone with respect to geometric mean concentrations (GMCs) to each discrete pertussis antigen (pertussis toxoid [PT], filamentous haemagglutinin [FHA] and pertactin [PRN]) one month after Boostrix® vaccination. |
|
E.2.2 | Secondary objectives of the trial |
•To evaluate the immunogenicity of MenACWY-TT co-administered with Boostrix® or administered alone in all three study groups with respect to (1) the percentage of subjects with rSBA titres ≥ 1:8, ≥ 1:128 prior to and one month after MenACWY-TT vaccination, and (2) the vaccine response one month after MenACWY-TT vaccination.
•To evaluate the immunogenicity of Boostrix® co-administered with MenACWY-TT compared to Boostrix® administered alone with respect to (1) anti-D and anti-T GMCs, and (2) a booster response to PT, FHA and PRN one month after Boostrix® vaccination in all three study groups.
•To compare the immunogenicity of MenACWY-TT given one month after Boostrix® to MenACWY-TT given one month before Boostrix® and vice versa.
•To evaluate the safety and reactogenicity after vaccination with MenACWY-TT and Boostrix® in terms of solicited symptoms, unsolicited symptoms, serious adverse events and new onset of chronic illnesses throughout the study following each vaccination.

•Previous vaccination with a meningococcal vaccine.
•History of meningococcal disease.
•Vaccination with a DTP-containing vaccine within the previous five years.
•History of serious allergic reaction following any other DTP-containing vaccine or any component of the study vaccines.
•History of encephalopathy within seven days following administration of a previous dose of pertussis vaccine that is not attributable to another identifiable cause.
•Temperature of ≥ 40.5°C (105°F) within 48 hours of receipt of a previous dose of DTP vaccine, not due to another identifiable cause.
•Collapse or shock-like state within 48 hours of receipt of a previous dose of DTP vaccine.
•Seizures with or without fever within three days of a previous dose of DTP vaccine.
•Severe Arthus-type hypersensitivity reactions following a prior dose of tetanus toxoid (TT) within the previous ten years.
•Any confirmed or suspected immunosuppressive or immunodeficient condition, based on medical history and physical examination during the study period.
•History of any reaction or hypersensitivity likely to be exacerbated by any component of the vaccine(s).
•Progressive neurologic disorder, uncontrolled epilepsy or progressive encephalopathy.
•History of any neurologic disorders or seizures, including Guillain-Barré syndrome (GBS). History of a simple, single febrile seizure is permitted.
•Bleeding disorders, such as haemophilia or thrombocytopenia, or subjects on anticoagulant therapy.
•Administration of immunoglobulins and/or any blood products within the three months preceding the first dose of study vaccine, or planned administration during the study period.
•Pregnant or lactating female.
•Female planning to become pregnant or planning to discontinue contraceptive precautions.
•Family history of congenital or hereditary immunodeficiency.
•Major congenital defects or serious chronic illness.
•Acute disease and/or fever at the time of enrolment.
-Fever is defined as temperature ≥ 37.5°C /99.5°F for oral, axillary or tympanic route.
-Subjects with a minor illness (such as mild diarrhoea, mild upper respiratory infection) without fever may be enrolled at the discretion of the investigator.
