E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To demonstrate the equivalence of rMenB+OMV NZ lot 1 to rMenB+OMV NZ lot 2 when administered to adolescents, as measured by human serum bactericidal activity (hSBA) geometric mean titers (GMTs) against 3 N. meningitidis serogroup B reference strains (H44/76, 5/99, and NZ98/254) and as measured by ELISA geometric mean concentrations (GMCs) against vaccine antigen 287-953, approximately 30 days after a primary vaccination course of two doses administered one month apart. |
|
E.2.2 | Secondary objectives of the trial |
Immune response at one month after a primary vaccination course of two rMenB + OMV doses administered one month apart as measured by the percentage of subjects with hSBA ≥1:5 and as measured by the ratio of hSBA post-vaccination to pre-vaccination GMTs [GMR] against 3 N. meningitidis serogroup B reference strains (H44/76, 5/99, and NZ98/254) and as measured by the ratio of ELISA post-vaccination to pre-vaccination GMCs [GMR] against vaccine antigen 287-953.
Immune response at two weeks after a primary vaccination course of two rMenB+OMV NZ doses administered one month apart as measured by hSBA GMT, the ratio of hSBA post-vaccination to pre-vaccination GMTs [GMR], and the percentage of subjects with hSBA ≥1:5 against 3 N. meningitidis serogroup B reference strains (H44/76, 5/99, and NZ98/254) and
as measured by ELISA GMC and the ratio of ELISA post-vaccination to pre-vaccination GMCs [GMR] against vaccine antigen 287-953.

3. in good health as determined by the outcome of medical history, physical examination and clinical judgment of the investigator.
|

5. Antibiotics within 3 days (72 hours) prior to enrollment;
6. Pregnancy or nursing (breastfeeding) mothers;
7. Females of childbearing age who have not used or do not plan to use acceptable birth control measures, for the 2 months duration of the study. Oral, injected or implanted hormonal contraceptive, diaphragm, condom, intrauterine device or sexual abstinence are considered acceptable forms of birth control. If sexually active the subject must have been using one of the accepted birth control methods for at least 30 days prior to study entry;
8. Any serious chronic or progressive disease (e.g., neoplasm, diabetes, cardiac disease, hepatic disease, progressive neurological disease or seizure disorder; autoimmune disease, HIV infection or AIDS, or blood dyscrasias or diathesis, signs of cardiac or renal failure or severe malnutrition).
9. Known or suspected impairment/alteration of the immune system, immunosuppressive therapy, including use of corticosteroids in immunosuppressive doses or chronic use of inhaled high-potency corticosteroids within the previous 60 days. [Use of topical corticosteroids administered during the study in limited areas (i.e., eczema on knees or face or elbows) of the body is allowed]; immunostimulants;
10. Receipt of blood, blood products and/or plasma derivatives, or a parenteral immunoglobulin preparation within the previous 90 days;
11. History of severe allergic reactions after previous vaccinations or hypersensitivity to any vaccine component;
12. Receipt of or intent to immunize with any other vaccine(s) within 30 days prior (60 days for live viral vaccines) and throughout the study period (exception: licensed flu-vaccine should not be administered within 14 days prior to enrollment; routine vaccine may be administered after the blood draw at the last study visit);
13. Participation in another clinical trial within the last 90 days or planned for during study;
14. Family members and household members of research staff;
15. Any condition which in the opinion of the investigator and/or the Regional MD may interfere with the evaluation of the study objectives

E.5 End points |
E.5.1 | Primary end point(s) |
• hSBA GMT at one month after the second vaccination for each of the three reference strains. Consistency of the immune response of the 2 lots of rMenB+OMV NZ will be assessed based on the ratio of the hSBA GMTs for each of the three reference strains at one month after the second vaccination. The equivalence interval will be (0.5, 2.0). |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Day 61, ie, one month after the second vaccination |
|
E.5.2 | Secondary end point(s) |
• The percentage of subjects in each lot with hSBA ≥1:5 at one month after the second vaccination for each of the three reference strains (H44/76, 5/99, and NZ98/254) for each vaccine group.
• The hSBA GMT increase (post-vaccination to pre-vaccination geometric mean ratio [GMR]) and associated two-sided 95% CI at each time point for each of the three N. meningitidis serogroup B reference strains and for each vaccine group.
• The ELISA GMC increase (post-vaccination to pre-vaccination GMR) and associated two-sided 95% CI at each time point for vaccine antigen 287-953 and for each vaccine group.
• The hSBA GMT and associated two-sided 95% CI at two weeks after the second vaccination in a subset of approximately 160 subjects (approximately 80 per lot) for each of three N. meningitidis serogroup B reference strains (H44/76, 5/99, and NZ98/254) and for each vaccine group.
