About this study

Official title: Phase 2 Study to Evaluate the Safety of and the Immunogenicity to an Adjuvanted A(H1N1)v Influenza Vaccine in HIV-Infected Adults

This is a randomized, open label, phase II trial to evaluate the safety and immunogenicity of two different schedules of vaccination against influenza A H1N1 in HIV-infected individuals, in which each of the randomized groups will be compared with HIV-negative volunteers vaccinated with the regimen indicated by the Brazilian National Immunization Program. Will be included in the study HIV-infected patients, stratified by CD4 count (< 200 cells/mm3 or > 200 cells/mm3) at the time of screening for the study, not receiving antiretroviral therapy treatment or receiving stable treatment for at least 8 weeks, with no plans to change over the next 6 months, eligible to receive vaccine against influenza A H1N1. The control group will be formed by HIV-negative individuals, confirmed by serology performed at screening, eligible to receive vaccine against influenza A H1N1. Patients infected with HIV will receive one of two possible vaccination regimens: 1) 3.75 µg in two applications 21 days apart, 2) 7.5 µg in two applications 21 days apart. The volunteers in the control group will receive a single application of 3.75 µg dose of the vaccine. The study's hypotheses are: 1) The vaccine against the H1N1 virus promotes antibody titers above the level specified for protection (seroconversion), being as safe and well tolerated in patients HIV-1 infected as in non HIV-infected volunteers; 2) The proportion of seroconversion for H1N1 virus vaccine at a dose of 3.75 µg in HIV-1-infected patients is similar to the proportion of seroconversion induced by the same vaccine at a dose of 7.5 µg; 3)The proportion of seroconversion with one dose of the vaccine against H1N1 virus is similar to the proportion after the second dose.

What is being measured

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

  1. proportions of seroconversion

    proportions of seroconversion for influenza A H1N1 in each of the four subsets of HIV-positive patients, and in the control group

    Measured: 21 days after vaccination regimen

  2. proportions of seroprotection

    proportions of seroprotection for influenza A H1N1 in each of the four subsets of HIV-positive patients and in the control group

    Measured: 21 days after vaccination regimen

  3. Safety of the A H1N1 vaccine at two different regimens in HIV-infected adults

    Safety and tolerability of the vaccine against H1N1 virus in different doses and administration regimens in IV-infected adults

    Measured: 1 months after vaccination

Secondary outcomes (4)
  1. Prevalence of A H1N1 influenza symptomatic disease in the study population

    proportions of the vaccine's protective factor against influenza A H1N1 in each of the four subsets of HIV-positive patients and in the control group

    Measured: 12 months after vaccination

  2. Persistence of antibodies against H1N1 virus

    Evaluate the persistence of antibody titers against H1N1 virus after the vaccine series in HIV-infected patients and control group

    Measured: 12 months after vaccination

  3. Changes in HIV viral load and CD4

    Assess changes in HIV-1 viral load and CD4+ counts after the vaccine series.

    Measured: 12 months after vaccination

  4. Cellular immune responses to H1N1 vaccination in HIV-infected patients

    Determine the cellular immune responses and their correlation to the development and magnitude of responses to H1N1 virus, and compare the cellular immune responses

    Measured: 12 months after vaccination

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Adjuvanted vaccine against H1N1 influenza virus (GSK) in people with HIV Infection, run by Oswaldo Cruz Foundation at 1 site in Brazil.

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 11 inclusion and 11 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 18 Jul 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 Brazil. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

proportions of seroconversion (time frame: 21 days after vaccination regimen). 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 NCT01155037, which also lists 1 linked publication.

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 18 Jul 2018.
