About this study

Official title: Influenza Vaccine Efficacy Against Childhood Pneumonia in an Urban Tropical Setting

Pneumonia is the leading cause of child death worldwide. Data from Bangladesh indicates that influenza has a substantial association with pneumonia among children less than two years old. This study will use commercially available trivalent inactivated vaccine (killed vaccine) to see if it can prevent early childhood pneumonia among children less than two years old. The study will vaccinate children across three seasons (3 years), and look at the effect on the attack rate of pneumonia, as well as its effects on laboratory-confirmed influenza. It will also look at the effect on laboratory-confirmed influenza illness among the non-vaccinated household contacts of all ages of these children.

Read the detailed description

Pneumonia is the primary cause of child mortality worldwide. The global community is considering interventions to reduce pneumonia burden, including vaccines. Most attention is focused on bacterial vaccines. Influenza vaccine has not received attention due to lack of influenza burden data from high pneumonia endemic settings, and poor understanding of how influenza contributes, independently and with other pathogens, to childhood pneumonia burden. Data from Bangladesh indicate that influenza has a high incidence of over 10% per year among children < 5 years, and that among children who get influenza infection, 28% develop pneumonia, including severe pneumonia. Influenza-infected children who develop pneumonia are significantly younger (< 2y) than those who do not. Due to the high influenza incidence, and the high proportion of influenza-infected children who develop pneumonia, influenza is a major contributor to childhood pneumonia, not only in Bangladesh, but likely throughout the pneumonia endemic tropical and sub-tropical belt. Although trials have been conducted to examine influenza vaccine impact on influenza, none have been conducted specifically to determine the effect on childhood pneumonia, particularly among those < 2 years who are at highest pneumonia risk. We propose to conduct such a trial.

The project goal is to determine whether influenza vaccine (trivalent inactivated vaccine or TIV) can reduce childhood pneumonia burden including: influenza-associated, other aetiology-mediated, and overall pneumonia incidence. The specific objectives are to determine influenza vaccine efficacy on 1) early childhood pneumonia (children < 2 years), 2) laboratory-confirmed influenza and 3) the rates of influenza-specific complications including severe disease, hospitalisation, and otitis media. Secondary objectives include determining the effect of influenza vaccine on household transmission and associated complications among all age groups, the effect on proven non-influenza viral and bacterial invasive diseases, the occurrence of adverse events associated with the vaccine, and to measure immune responsiveness to influenza vaccine in these young children.

Critical milestones include comparison between vaccinated and vaccine-controlled children of 1) pneumonia incidence (vaccine efficacy against pneumonia), 2) influenza incidence (vaccine efficacy against influenza) 3) rates of other clinical syndromes (vaccine efficacy against other childhood morbidity). Milestones related to secondary objectives include comparison between vaccinated and vaccine-controlled children of 1) rates of laboratory-confirmed infection and clinical illness among household contacts and 2) rates of other invasive bacterial and viral diseases, and 3) rates of adverse events. We will also measure childhood immune responsiveness to influenza vaccine and relate that to observed rates of infection and clinical illness.

What is being measured

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

  1. Clinical pneumonia

    Children who present with age-specific tachypnoea, cough with crepitations on auscultation will be determined to have clinical pneumonia. If this occurs ≥14 days post two doses of influenza vaccine, they will be considered fully vaccinated. Comparisons will be made between groups on the number of such episodes.

    Measured: Up to 12 months post-vaccination

  2. Laboratory confirmed influenza infection

    Influenza infection will be determined by RT-PCR among children with signs and symptoms of febrile and/or respiratory symptoms, including pneumonia.

    Measured: Up to 12 months post-vaccination

Secondary outcomes (5)
  1. Indirect effects

    Laboratory-confirmed influenza will assessed by RT-PCR among household contacts who present with signs and symptoms of febrile and/or respiratory illness.

    Measured: Up to 12 months post-vaccination

  2. Epidemiological and clinical characteristics of influenza infection

    The epidemiological (seasonality and incidence) and clinical (important clinical syndromes, clinical course, complications and outcomes) characteristics of laboratory-confirmed influenza infection in this age group will be documented.

    Measured: Up to 12 months post vaccination

  3. Effect on non-influenza viral and bacterial invasive disease

    We will measure the influenza vaccine effect on invasive disease by other pathogens, including pneumococcus, Haemophilus, and several respiratory viruses.

    Measured: Up to 12 months post vaccination

  4. Immunogenicity

    We will obtain serum on a 20% subsample of children pre-dose 1, pre-dose 2 and 4 weeks post-dose 2 to determine the immune responsiveness to the vaccine.

    Measured: Within 4 months of vaccine administration

  5. Adverse events associated with the vaccine

    Adverse events will be monitored, beginning the day of vaccination and for the next 7 days (8 time points) using standardised questionnaires.

    Measured: Beginning Day 0 (day of vaccination) and for the next 7 days

A Phase 3 study testing Trivalent inactivated influenza vaccine in people with Pneumonia and Laboratory Confirmed Influenza, run by International Centre for Diarrhoeal Disease Research, Bangladesh at 1 site in Bangladesh.

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 1 inclusion and 1 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 25 Sep 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 Bangladesh. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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?

Clinical pneumonia (time frame: Up to 12 months post-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?

On the ClinicalTrials.gov record for NCT01319955, 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 25 Sep 2017.
