InfluenzaPhase 1NCT00318058
Safety Study of an Adjuvanted Candidate Influenza Vaccine to Prevent Influenza Disease in the Elderly Population
A Phase 1 study testing influenza vaccine Fluarix, Adjuvanted Fluarix in people with Influenza, run by GlaxoSmithKline at 1 site in Belgium.
Trial summary
As influenza vaccine efficacy is reported to be lower in elderly subjects compared to healthy adults, probably as a result of immunosenescence, there is a desire to devise ways to increase the current vaccines efficacy for this target population. Read more about this study

About this study
Official title: A Phase I/II, Open, Controlled Study in Order to Evaluate the Reactogenicity and the Immunogenicity of GlaxoSmithKline Biologicals Influenza Candidate Adjuvanted Vaccine in an Elderly Population Aged Over 65 Years Previously Vaccinated in 2004 With the Same Candidate Vaccine
As influenza vaccine efficacy is reported to be lower in elderly subjects compared to healthy adults, probably as a result of immunosenescence, there is a desire to devise ways to increase the current vaccines efficacy for this target population. Adjuvants are known to boost immune responses, thus representing one way to increase the efficacy of the current GlaxoSmithKline Fluarix™ influenza vaccine in elderly subjects. The purpose of this study is to evaluate the immunogenicity and the reactogenicity of a revaccination with the adjuvanted GlaxoSmithKline influenza vaccine administered intramuscularly about 1 year after administration of the first dose of vaccine. For immunogenicity and safety evaluations, subjects who have already received Fluarix™ during the preceeding year will receive a dose of commercial vaccine and will form the control group of this trial.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing influenza vaccine Fluarix, Adjuvanted Fluarix in people with Influenza, run by GlaxoSmithKline at 1 site in Belgium.
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 9 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 8 May 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 Belgium. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
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?
Percentage, intensity and relationship to vaccination of local (at the injection site) and general signs and symptoms during a 21 day follow-up period after 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?
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 8 May 2017.
