About this study
Official title: Safety and Immunogenicity Following Meningococcal and Pneumococcal Immunization Among Adult People Living With HIV: A Single Center, Non-blinded, Randomized Clinical Trial
MENPI is an investigator-initiated single-centre randomized controlled trial which aims to assess the efficacy and safety of meningococcal and pneumococcal vaccination in adults living with HIV receiving antiretroviral treatment.
Participants are randomized 1:1 to either a two-dose Menveo® and Bexsero® regimen or a Prevenar13®/Pneumovax23® prime-boost regimen at day 0 and day 60 and cross over on day 90. All participants will follow an identical follow up program including plasma collection, pharyngeal swab, and adverse event registration.
Immunogenicity will be determined on venous blood sampled at 30 days post-vaccination and yearly for five years.
- Conditions
- Hiv, Meningococcal Infections, Pneumococcal Infections
- Being tested
- Neisseria meningitidis oligosaccharide conjugate vaccine and recombinant protein-based vaccine, 13 valent pneumococcal conjugate vaccine and 23 valent pneumococcal polysaccharide vaccine
- Medical subject headings
- Acquired Immunodeficiency Syndrome, Meningococcal Infections, Pneumococcal Infections
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Neisseria meningitidis oligosaccharide conjugate vaccine and recombinant protein-based vaccineDrug
Also called Menveo® and Bexsero®
One dose (0.5 ml) of conjugate vaccine against meningococcal serogroups ACWY (Menveo®) and one dose of a recombinant protein-based vaccine against meningococcal serogroup B (Bexsero®) at day 0 followed by another dose (0.5 ml) of each vaccine at day 60.
13 valent pneumococcal conjugate vaccine and 23 valent pneumococcal polysaccharide vaccineDrug
Also called Prevenar13® and Pneumovax23®
One dose (0.5 ml) of pneumococcal conjugate vaccine (Prevenar13®) at day 0 and one dose (0.5 ml) of pneumococcal polysaccharide vaccine (Pneumovax23®) at day 60.
| Study group | Role | What they receive |
|---|---|---|

The primary outcome is the main question the study is designed to answer.
Change in immunogenic response from baseline, Menveo
A ≥4-fold rise in rabbit complement source (rSBA) for the four serogroups A, C, Y, and W-135. Seroprotection is defined as an rSBA titre ≥1:8 and patients will be classified as previously immune if baseline rSBA is ≥1:8.
Measured: Day 30 and year 1, 2, 3, 4, and 5 post-vaccination
Change in immunogenic response from baseline, Bexsero
A ≥4-fold rise in antibody titers against a panel of four meningococcal serogroup B reference strains between pre-vaccination and post-vaccination timepoints, or a post-vaccination antibody titre ratio of ≥1:4 for individuals who were seronegative before vaccination.
Measured: Day 30 and year 1, 2, 3, 4, and 5 post-vaccination
Change in immunogenic response from baseline, Prevenar13/Pneumovax23
A ≥2-fold rise in serum anti-capsular IgG GMC for 12 shared pneumococcal polysaccharides (1, 3, 4, 5, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F)
Measured: Day 30 and year 1, 2, 3, 4, and 5 post-vaccination
Secondary outcomes (5)
Number of participants with immediate adverse events
Measured: 30 minutes post-vaccination
Number of participants with short term adverse events
Measured: Day 5 post vaccination
Number of participants with long term adverse events
Measured: Day 90 post-vaccination
Streptococcus pneumoniae carriage rates
Proportion of study subject with a culture or PCR positive pharyngeal swab sample
Measured: Baseline and day 30 post-vaccination

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Neisseria meningitidis oligosaccharide conjugate vaccine and recombinant protein-based vaccine and 13 valent pneumococcal conjugate vaccine and 23 valent pneumococcal polysaccharide vaccine in people with Hiv and Meningococcal Infections, run by Thomas Benfield at 1 site in Denmark.
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 12 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: looking for participants now, as of the sponsor's last update on 6 May 2021. 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 Denmark. 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?
Contact Michaela Tinggaard, M.D. (22326800, michaela.tinggaard@regionh.dk), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in immunogenic response from baseline, Menveo (time frame: Day 30 and year 1, 2, 3, 4, and 5 post-vaccination). 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 NCT04875819, which also lists 10 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 6 May 2021.
