About this study

Official title: Phase 1 Dose Esc Study of Safety and Immun of 3 Injections, Given at 0, 6 and 24 Wks, of Grp B Meningococcal 44/76 MOS NOMV 5D Vaccine Admin to Healthy Subjs IM With and Without Adjuvant

The purpose of this study is to determine if the vaccine called Group B Meningococcal 44/76 MOS NOMV 5D Vaccine is safe and free from side effects and if it will protect people from meningitis.

This study will vaccinate three groups of people. In the first 2 groups, the study will be double-blinded. This means that neither the volunteer or the medical team will know which formulation of the vaccine was administered. The third group of volunteers and the medical team will know that they are receiving the higher dose of the vaccine.

Read the detailed description

Meningococcal disease is a contagious bacterial disease caused by Neisseria meningitidis that can kill children and young adults very quickly. Meningococci are divided into distinct sergroups based on their polysaccharide outer capsule, which is the usual target antigen for vaccines. Serogroup A is the main cause of epidemics in Africa and in the United States, sergroups B, C and Y predominate. In the United States, no vaccine is yet available to offer protection against serogroup B which currently accounts for 32% of all meningococcal disease in the United States.

This study serves as a proof of concept for our new NOMV Group B single strain monovalent vaccine model which is obtained from a genetically modified parent. If successful we plan to develop a multivalent Group B vaccine for routine use for military recruits at the beginning of basic training, for college students, particularly those who live in dormitories, and for use by travelers to countries recognized as having hyperendemic disease.

What is being measured

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

  1. Safety: Severity Summary of Solicited and Unsolicited Adverse Events

    Solicited and unsolicited summary of severity of adverse events (AEs) during the 7 day follow-up period after each vaccination

    Measured: 7 day f/u period after each vaccination

  2. Safety: Adverse Event Type Summarized by Dose

    Adverse events summarized by type and dose

    Measured: 7 days after each vaccination

Secondary outcomes (2)
  1. Weeks to Serconversion

    Weeks to seroconversion evaluated by serum bactericidal assay. Immunogenicity was determined by assessing the number of subjects, in each cohort, who seroconverted. Seroconversion was defined as a 4-fold or greater increase in serum bactericidal antibodies against the vaccine strain. The geometric mean bactericidal titer (GMT) for each group was determined prior to vaccination and at 2 weeks after each vaccination. For each group, the GMT ratio relative to baseline and after 1, 2, or 3 vaccinations and the 95% 2-sided confidence interval was determined. A seroconversion of ≥50% of the subjects after 2 or more doses would meet the criteria for further vaccine development.

    Measured: 26 weeks

  2. Percentage of Subjects With 2-fold and 4-fold Increase IgG Antibody Conversion

    Percentage of subjects with ELISA 2-fold and 4-fold increase from baseline IgG antibody Conversion

    Measured: 26 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing 25ug Group B Meningococcal 44/76 MOS NOMV 5D Vaccine and 50ug Group B Meningococcal 44/76 MOS NOMV 5D Vaccine in people with Meningitis, Meningococcal, Serogroup B, run by U.S. Army Medical Research and Development Command at 1 site in United States.

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 5 inclusion and 10 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: finished, as of the sponsor's last update on 29 Oct 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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

Are results available for this study?

Yes. Results are posted in the registry (first posted 29 Oct 2018). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Safety: Severity Summary of Solicited and Unsolicited Adverse Events (time frame: 7 day f/u period after each vaccination). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 29 Oct 2018.
