Trial summary

Respiratory Syncytial Virus (RSV) is a virus that causes chest infections. It is the single most important cause of severe respiratory illness in infants and young children, and severe RSV infection early in life is associated with an increased risk of later developing asthma.

About this study

Official title: Analysis of the Immune Response to Respiratory Syncytial Virus (RSV) Exposure in a Paediatric Population

Respiratory Syncytial Virus (RSV) is a virus that causes chest infections. It is the single most important cause of severe respiratory illness in infants and young children, and severe RSV infection early in life is associated with an increased risk of later developing asthma. RSV also causes severe disease in elderly and immune-compromised adults, and the amount of RSV disease in the elderly is similar to that from seasonal flu. The virus is transmitted in the secretions of the upper respiratory tract of infected individuals and by contact with contaminated surfaces (such as toys). Hospital outbreaks, especially on paediatric and neonatal wards, are not uncommon.

Infection by RSV does not develop a natural long-lasting protection against re-infection (like, for example, measles does). In the USA nearly all children by 24 months of age have been infected at least once with RSV, and about half will have experienced two infections. There is no effective anti-viral drug to treat an infection and the only way of managing cases of severe infection is through supporting organs, such as the lungs, to withstand and recover from the illness.

There remains a real need to develop an effective vaccine to prevent severe infections caused by RSV. A better understanding of the way the immune system responds to RSV in children would aid the development of such a vaccine.

The purpose of this study is to increase our understanding of how the immune system responds to RSV. Only limited data is available on some important components of the immune response and this study is designed to measure these in more detail. This is done using a single blood sample.

A total of 35 children are anticipated to be recruited to this study, at ages when we expect to see differences in the immune response to RSV;

  • 5 infants aged between 2 and 4 months (Group 1), who have not yet been exposed to RSV
  • 20 infants aged between 6 and 12 months (Group 2), who will have had exposure to one single RSV season in the winter of 2011/12
  • 10 children aged between 3 and 6 years (Group 3), who have been exposed to RSV over several winter seasons

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Blood sampleProcedure or surgery

    An extra volume of blood is obtained, with prior consent, when phlebotomy is required for another unrelated clinical reason.

What is being measured

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

  1. To assess the induction of RSV-specific immune responses in blood following natural exposure

    The following assays characterise the primary objective:

    • Anti-RSV antibody concentration and neutralisation capacity
    • T-cell immune responses

    Measured: one year

Questions about this trial

What is this clinical trial studying?

An observational study of Respiratory Syncytial Virus Infections, 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 4 inclusion and 6 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 10 Sep 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 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.

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 assess the induction of RSV-specific immune responses in blood following natural exposure (time frame: one year). 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 10 Sep 2018.
