About this study

The goal of this study is to determine if there is a difference in shedding (primary objective) and in immunogenicity and safety (secondary objectives) between HIV-positive and HIV-negative children and young adults who are receiving the quadrivalent live-attenuated influenza vaccine (QLAIV).

Read the detailed description

QLAIV is an intranasal vaccine that works by using 4 different attenuated strains of influenza virus that will replicate in the nose and stimulate an immune response in recipients that should protect them if they are infected with one of those strains of influenza in the future. A couple of studies have shown an increase in duration that the viruses remain in the nose in immunocompromised people. Those studies were done using the trivalent vaccine, so the investigators would like to evaluate the quadrivalent vaccine, and there is still a need for additional data to help understand the duration of shedding. If shedding is prolonged in HIV-infected children and young adults, it would be important to know for contacts of those individuals who are very immunocompromised. Shedding will be measured by looking for influenza RNA in nasopharyngeal swabs taken at baseline, 2-5 days, 7-10 days and 14-21 days after the intranasal immunization.

The live-attenuated influenza vaccines have been shown to have increased effectiveness in children and they stimulate the immune system in a different way than the inactivated influenza vaccines (TIV or QIV). In this study, the investigators will have the opportunity to compare the immunogenicity of QLAIV, measured at baseline and 14-21 days post-vaccination, in HIV-infected and uninfected children, adolescents and young adults. Although prior studies of LAIV in HIV-infected and other immunocompromised children and adults have not shown any increase in serious adverse events, safety will be actively monitored for the first 30-45 days through a study-specific questionnaire administered at each clinic or phone visit and by asking the subjects to keep a diary of side effects. Safety will be monitored passively throughout the course of the study.

What is being measured

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

  1. Number of Participants With Shedding for at Least One of the Influenza Strains Included in the QLAIV in the First 21 Days After Vaccine Administration Days in HIV-positive and Control Groups.

    Measure PCR positivity for any of the influenza subtypes included in QLAIV between baseline (day 0) and the last study visit at 14-21 days after vaccine. Compare number of participants with PCR positivity for any of the vaccine-strain influenza virus strains in each patient group.

    Measured: 21 days

  2. Number of Participants With Shedding for at Least One of the Influenza Strains Included in the QLAIV Vaccine at Each of the 4 Study Visits, Days 0 (Baseline), 2-5, 7-10, and 14-21 in HIV-positive and Control Groups.

    Measure PCR positivity for any of the influenza subtypes included in QLAIV at visit 1 (day 0), visit 2 (days 2-5), visit 3 (days 7-10) and visit 4 (days 14-21). Compare number of participants with shedding for any subtype in each patient group. (The study was powered based on the 7-10 day data.)

    Measured: day 0-21 post-vaccine

Secondary outcomes (2)
  1. Number of Participants With Adverse Events Within 14 Days After Vaccination

    The investigators will compare the number of adverse events (AE) reported by AE category within 14 days after vaccination as reported by each participant. Data will reflect whether a participant ever reported the AE, and not the number of times the AE was reported.

    Measured: 14 days after vaccination for AEs; up to 30 days for unscheduled visits

  2. Number of Participants Reaching Seroprotection (HAI ≥ 40) Within the HIV-positive and Control Groups.

    The investigators will measure hemagglutinin inhibition (HAI) on blood samples #2 (14-21 days after vaccination) for all participants. The investigators will also compare the number of participants reaching HAI ≥ 40 for each virus sub-type contained in the vaccine.

    Measured: 14-21 days

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Quadrivalent Live Attenuated Influenza Vaccine in people with Human Immunodeficiency Virus (HIV), run by University of Colorado, Denver 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 11 inclusion and 20 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 20 Nov 2017. 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 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?

Yes. Results are posted in the registry (first posted 16 Oct 2017). 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?

Number of Participants With Shedding for at Least One of the Influenza Strains Included in the QLAIV in the First 21 Days After Vaccine Administration Days in HIV-positive and Control Groups. (time frame: 21 days). 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 20 Nov 2017; AzTrials last refreshed its copy on 8 Nov 2026.
