About this study

Official title: A Phase I, Single Centre, Open-label Dose-escalation Study to Assess the Safety and Immunogenicity of Three Doses of 25µg or 50 µg of Meningococcal Serogroup B Outer Membrane Vesicle Vaccine MenPF-1

In this study the investigators are testing a new vaccine against Neisseria meningitidis, the leading infective cause of childhood death in the UK. This bug (also known as meningococcus) can infect the lining of the brain (meningitis) or the blood stream (septicaemia) and can affect all ages, but especially children, adolescents and young adults.

The bug is classified into different groups based on its outer capsule (or shell), and this study will test a new vaccine to protect against group B meningococcus (MenB) disease, which is the most common type in the UK.

Read more

Vaccines are given to prepare the immune system to fight an infection. Vaccines work by stimulating the immune system to produce specialised proteins (called antibodies) and white blood cells designed to kill the bug later in life if needed.

Vaccines against other types of meningococcus have been developed and saved many lives. However MenB is different because its outer capsule does not stimulate the immune system very effectively. There is therefore no broadly effective vaccine against MenB disease.

Read the detailed description

The vaccine the investigators are testing in this study is known as MenPF-1, and uses two bacterial proteins called PorA and FetA. PorA works to move particles across the bacterial cell wall, and FetA is needed to bind to iron that the bacteria need in order to grow. These proteins are found on almost all meningococcal bugs so they are an excellent target for the immune system, and it is thought that they could be the key to developing a new vaccine against MenB disease.

MenPF-1 is a type of vaccine known as an Outer Membrane Vesicle (OMV) vaccine. This means that it has been produced from 'blebs' of the meningococcal bug's outer membrane, released by the meningococcus both during natural infection and in the laboratory. These outer membrane vesicles contain the PorA and FetA proteins, so can be used to make vaccines. The techniques used to produce the OMVs to make MenPF-1 are the same as those used in other very similar safe and effective vaccines. The MenB strain that the investigators use naturally produces PorA protein, and has been genetically modified to produce increased amounts of FetA for the OMV vaccine.

MenPF-1 contains:

  • Many proteins, but especially PorA and FetA
  • Aluminium, which is safe and commonly used in many vaccines to better activate the immune system
  • Sugar and water for injection

It is worth noting that the vaccine product MenPF-1 is designed to work against MenB and, even if successful, would not protect against all forms of meningitis. Also, it is not a live vaccine and therefore cannot cause a meningitis infection.

What is being measured

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

  1. To investigate safety and tolerability of 25 µg or 50 µg of the serogroup B meningococcal protein vaccine MenPF-1

    This will be measured by the recording and assessment of the following local and systemic adverse events following administration of each vaccine dose:

    1. Tenderness and pain at the injection site
    2. Induration
    3. Redness
    4. Swelling
    5. Headache
    6. Malaise
    7. Myalgia
    8. Nausea and/or vomiting
    9. Fever
    10. Blood parameters
    11. Any unsolicited symptom(s) not listed above

    Measured: 20 weeks

Secondary outcomes (1)
  1. Immunogenicity

    Immunological assays to study the immune responses to vaccines, including:

    1. Serum bactericidal antibody (SBA) assay.
    2. Antibody concentration against vaccine antigens.
    3. Quantification of circulating vaccine-induced B-cells.
    4. Quantification of vaccine-induced, antigen specific T-cell responses and associated cytokine production.
    5. Serum opsonophagocytic activity.
    6. Gene expression profile after immunization and DNA storage for investigation of the genetic associations with the immune response.

    Measured: 20 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing MenPF-1. in people with Serogroup B Meningococcal Disease, run by University of Oxford at 1 site in United Kingdom.

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 7 inclusion and 17 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 7 Dec 2023. 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 Kingdom. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

To investigate safety and tolerability of 25 µg or 50 µg of the serogroup B meningococcal protein vaccine MenPF-1 (time frame: 20 weeks). 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 NCT01640652, which also lists 2 linked publications.

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 7 Dec 2023.
