About this study

Official title: A Phase 4, Single-arm, Open-label, Multi-center Study to Assess the Immune Response and Safety of the Meningococcal Group B Vaccine MenB+OMV NZ When Administered to Healthy Infants From 2 Months of Age in the Republic of Korea

The purpose of this study is to assess the safety and immune responses of rMenB+OMV NZ vaccine when administered to healthy infants from 2 months in the Republic of Korea according to a 2-dose primary schedule and 1 booster dose.

Read the detailed description

As a post-approval commitment to the Ministry of Food and Drug Safety, Bexsero, which is approved in the Republic of Korea for active immunization against MenB, participants will receive a primary series of 2 doses of rMenB+OMV NZ vaccine, with the first dose given at 2 to 5 months of age and the second dose 2 months later. A third dose (booster) will be administered at 12 to 15 months of age. Routine infant vaccines may be administered as per the Korean Routine Immunization Schedule. However, there will be a minimum interval of 14 days before and after the administration of rMenB+OMV NZ vaccine or any other vaccine (21 days for live attenuated vaccines and 7 days for influenza vaccines).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percentage of participants with hSBA titers equal to or higher than (≥) Lower Limit of Quantitation (LLOQ) against all MenB indicator strains for the vaccine antigens at Day 91

    The assessed strains are M14459, 96217, NZ98/254 and M13520.

    Measured: At Day 91 (30 days after completion of the primary series)

  2. Percentage of participants with hSBA titers equal to or higher than (≥) Lower Limit of Quantitation (LLOQ) against all MenB indicator strains for the vaccine antigens before the third (booster dose) vaccination

    The assessed strains are M14459, 96217, NZ98/254 and M13520.

    Measured: At any day between Day 241-391 (before the booster dose)

  3. Percentage of participants with hSBA titers equal to or higher than (≥) Lower Limit of Quantitation (LLOQ) against all MenB indicator strains for the vaccine antigens 30 days after the booster dose

    The assessed strains are M14459, 96217, NZ98/254 and M13520.

    Measured: At any day between Day 271 - 421 (30 days after the booster dose)

Secondary outcomes (2)

  1. Percentage of participants with any unsolicited adverse events (AEs)

    An AE is defined as an untoward medical occurrence in a clinical study participant, temporally associated with the use of a study intervention, whether or not considered related to the study intervention. An unsolicited AE (including both serious and nonserious AEs) is an AE that was either not included in the list of solicited events or could be included in the list of solicited events but with an onset outside the specified period of follow-up for solicited events. Unsolicited AEs must have been communicated by participant's parent(s)/Legally acceptable representative(s) who has signed the informed consent.

    Measured: Within 30 days after each vaccination and after any vaccination (vaccine administered at Day 1, Day 61, and any day between Day 241 - Day 391)

  2. Percentage of participants with AEs of special interest (AESI), Serious adverse events (SAEs), AEs leading to withdrawal and Medically attended AEs (MAAEs)

    AESIs includes seizures: febrile seizure and arthritis. An SAE is defined as any untoward medical occurrence that, at any dose: results in death; is life-threatening; requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent disability/incapacity. Any AE is defined as untoward medical occurrence in a clinical study participant, temporally associated with the use of a study intervention, whether or not considered related to the study intervention. A MAAE is an AE for which the participant received medical attention including any symptom or illness requiring hospitalization, or an emergency room visit, or visit to/by a healthcare professional.

    Measured: From Day 1 to any day between Day 421- Day 571 (throughout the study period)

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing rMenB+OMV NZ in people with Meningitis, Meningococcal, run by GlaxoSmithKline at 8 sites in South Korea.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 22 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 6 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 8 sites in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percentage of participants with hSBA titers equal to or higher than (≥) Lower Limit of Quantitation (LLOQ) against all MenB indicator strains for the vaccine antigens at Day 91 (time frame: At Day 91 (30 days after completion of the primary series)). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06113198.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Apr 2026; AzTrials last refreshed its copy on 7 Nov 2026.
