About this study

Official title: Proteomic Profiling for Influenza Vaccination, 2nd Study: FluMist

The purpose of this study is to look at changes that occur in blood and nasal swab samples after a person's immune system responds to receiving a flu vaccine. The investigators will look at the immune response in 50 healthy volunteers, between 21 and 49 years of age, after they have been vaccinated with 1 dose of a flu vaccine sprayed into the nose. A blood sample and nasal swab of each nostril will be collected from volunteers before they receive the flu vaccination. After receiving the flu vaccine, volunteers will record health changes and daily temperatures on diary cards at home for 21 days. Blood will be drawn and nasal swabs will be collected from each volunteer at each of the 6 study visits. Volunteers will participate in the study for approximately 1 month. This study is being conducted at the Glennan Center for Geriatrics and Gerontology at Eastern Virginia Medical School.

Read the detailed description

This is a nonrandomized, non-comparative study conducted in 50 healthy subjects, between 21 and 49 years of age, who have been vaccinated with 1 dose (0.5 mL) of Influenza Virus Vaccine Live, Intranasal FluMistTM, a live trivalent nasally administered vaccine. The central hypothesis is that immune responses to vaccination can be quantified by proteomic profiling of serum and nasal proteins, and that host responses to different infectious agents are unique and can be "fingerprinted" by proteomics. Using influenza virus vaccination, this study proposes to use mass spectrometry platforms to profile and characterize proteins from serum samples obtained from recipients. These samples will be used to develop a proteomic profiling system for monitoring vaccine response, and will eventually allow earlier detection/diagnosis of infection. Annually, natural influenza infections cause serious international public health problems that are particularly severe in elderly people, who account for more than 90% of influenza mortality. The current trivalent split virus influenza vaccine is cost-effective, but its efficacy is greatly reduced in the elderly population. The long-term goal of the investigators' approach is to develop tools useful for reducing the morbidity and mortality of influenza from natural and potential bioterrorism-related infections by improving measures of vaccine efficacy and early diagnosis. This study is being conducted at the Glennan Center for Geriatrics and Gerontology at Eastern Virginia Medical School. Solicited adverse events (AEs) and daily temperatures will be collected on diary cards for 21 days. Unsolicited AEs will also be collected throughout the duration of the study. Blood will be drawn and nasal swabs will be collected from each subject at each of the 6 study visits. Subjects will participate in the study for approximately 1 month. The primary objective of this study is to analyze serum samples before and after FluMist intranasal attenuated live-virus influenza vaccination to identify surrogate markers reflective of the immune response by using surface-enhanced laser desorption/ionization-time of flight (SELDI-TOF) and matrix-assisted laser desorption/ionization-time of flight (MALDI-TOF) mass spectrometry proteomic profiling tools reflective of the immune response. Concurrent T-cell activation, cytokine assays, and hemagglutination inhibition (HI) serologic assays will correlate cellular and humoral responses to influenza vaccination with protein profiling changes. Proteins obtained from intranasal swabs pre and post vaccination will be analyzed. The investigators anticipate identifying multiple host response proteins from this analysis using combinations of gel electrophoresis, MALDI-TOF and tandem MS/MS approaches. The secondary objective is safety. Data on solicited reactions will be collected from Day 0 to Day 14. The time of occurrence of AEs will be used to determine if there is a correlation with the time of increase in certain protein biomarkers. The primary endpoint is to identify surrogate markers reflective of the immune response in serum and/or nasal proteins and to correlate these markers to cellular and humoral responses (demonstrated with T-cell activation, cytokine assays, and the hemagglutination inhibition [HI] serologic assays) to influenza vaccination. The secondary endpoint is safety. Data on local reactions and solicited systemic reactions will be collected from Day 0 to Day 14 and categorized according to severity. Unsolicited AEs will be collected and categorized throughout the study by severity, duration, and relatedness to vaccine. The time of occurrence of AEs will be used to determine if there is a correlation with the time of increase in certain protein biomarkers.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing FluMist in people with Influenza, run by National Institute of Allergy and Infectious Diseases (NIAID) 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 8 inclusion and 33 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 27 Aug 2010. 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 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?

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.

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 27 Aug 2010.
