Main objective of the trial

Immunogenicity: 1. To demonstrate that the immune response for Neisseria meningitidis group A (MenA), Neisseria meningitidis group C (MenC), Neisseria meningitidis group W (MenW), and Neisseria meningitidis group Y (MenY) induced by 2 doses of Neisseria meningitidis group A, B, C, W, and Y vaccine (MenABCWY ) is noninferior to the immune response induced by 1 dose of meningococcal groups A, C, Y, and W-135 oligosaccharide diphtheria conjugate vaccine (MenACWY-CRM) in both ACWY-naïve and ACWY-experienced participants, separately. 2. To demonstrate that the immune response for MenB induced by 2 doses of MenABCWY is noninferior to the immune response induced by 2 doses of Trumenba. Safety: To describe the safety profile of MenABCWY, as measured by local reactions, systemic events, adverse events (AEs), serious adverse events (SAEs), newly diagnosed chronic medical conditions (NDCMCs), medically attended adverse event (MAEs), and immediate AEs.

Protection of trial subjects

The study was in compliance with the ethical principles derived from the Declaration of Helsinki and in compliance with all International Council for Harmonisation (ICH) Good Clinical Practice (GCP) Guidelines. All the local regulatory requirements pertinent to safety of trial subjects were followed.

Recruitment details

Screening details

A total of 2431 subjects were enrolled and randomised in the study of which 18 subjects did not receive any vaccination. 2413 subjects received at least 1 dose of vaccination. 1 subject initially randomised to group 3 was excluded from safety population set as the subject received the wrong vaccination (Trumenba + saline).

ACWY-Naive: Group 1 MenABCWY + Saline

Arm description

On Day 1, Neisseria meningitidis group A, C, W, and Y (ACWY) naive subjects received a single dose of 0.5 millilitre (mL) Neisseria meningitidis serogroup A, B, C, W, Y (MenABCWY) intramuscularly into the left deltoid muscle along with 0.5 mL of saline intramuscularly into the right deltoid muscle (Vaccination 1). After 6 months, subjects received 0.5 mL of MenABCWY intramuscularly into the left deltoid muscle (Vaccination 2). Subjects were followed up for 6 months after last vaccination and contributed to both safety and immunogenicity analyses.

Percentage of Subjects Achieving At least 4-Fold Rise in Serum Bactericidal Assay Using Human Complement (hSBA) Titer From Baseline for Each of the MenACWY Strains: 1 Month After Vaccination 2 in Group 1 Compared to 1 Month After Vaccination 1 in Group 2 ^[1]

End point description

4-fold increase was defined as: for subjects with baseline hSBA titer below limit of detection (LOD) (or hSBA titer <1:4),response=hSBA titer >=1:16;baseline hSBA titer >=LOD and < lower limit of quantitation (LLOQ) (i.e. hSBA titer of 1:8), response=hSBA titer >=4times LLOQ; baseline hSBA titer >=LLOQ, response=hSBA titer >=4 times baseline titer. Exact 2-sided confidence interval (CI) using Clopper and Pearson method was presented. Post-vaccination(PV) 1 and PV2 evaluable immunogenicity population for Group 2 and Group 1 included subjects randomised to study group of interest; eligible at visit(V) 2 and 4, respectively; received vaccine at V1 or V1 and V3, respectively; blood drawn for assay testing at protocol-specified time points; at least 1 valid, determinate MenACWY or MenACWY/MenB assay result, received no prohibited vaccines/treatment and had no protocol deviations through V2 and V4 respectively. N= subjects evaluable for end point; n=subjects evaluable for specified rows.

Local reactions included pain at injection site, redness and swelling and were recorded by subjects in an electronic diary (e-diary). Redness and swelling were measured and recorded in caliper units. 1 caliper unit =0.5 centimeter (cm) and graded as mild: >2.0 to 5.0 cm, moderate: >5.0 to 10.0 cm and severe: >10.0 cm. Pain at injection site was graded as mild: did not interfere with daily activity, moderate: interfered with daily activity and severe: prevented daily activity. Percentage of subjects with local reactions at injection site on left arm were reported in this endpoint. Exact 2-sided CI was based on the Clopper and Pearson method.

Fatigue, headache, chills, muscle pain and joint pain were graded as mild: did not interfere with activity, moderate: some interference with activity and severe: prevented daily routine activity. Vomiting was graded as mild: 1 to 2 times in 24 hours(h), moderate: >2 times in 24h and severe: required intravenous hydration. Diarrhea was graded as mild: 2 to 3 loose stools in 24h, moderate: 4 to 5 loose stools in 24h and severe: 6 or more loose stools in 24h. Exact 2-sided CI was based on the Clopper and Pearson method.

End point description

Systemic events were recorded by subjects in e-diary. Fever was defined as temperature >=38.0 deg C and was categorised as 38.0 to 38.4 deg C, >38.4 to 38.9 deg C, >38.9 to 40.0 deg C and >40.0 deg C. Fatigue, headache, chills, muscle pain and joint pain were graded as mild: did not interfere with activity, moderate: some interference with activity and severe: prevented daily routine activity. Vomiting was graded as mild: 1 to 2 times in 24h, moderate: >2 times in 24h and severe: required intravenous hydration. Diarrhea was graded as mild: 2 to 3 loose stools in 24h, moderate: 4 to 5 loose stools in 24h and severe: 6 or more loose stools in 24h. Exact 2-sided CI was based on the Clopper and Pearson method. Safety population included all randomised subjects who received at least 1 dose of investigational product and had safety data reported after vaccination. Here, ‘Number of Subjects Analysed’ (N)=subjects evaluable for this endpoint.
