What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Seroconverted Subjects Against A/Indonesia/5/2005 (H5N1)
A seroconverted subject was defined as a vaccinated subject who had either a pre-vaccination (Day 0) reciprocal HI titer < 1:10 and a post-vaccination (Day 42) reciprocal titer ≥ 1:40, or a pre-vaccination reciprocal HI titer ≥ 1:10 and at least a 4-fold increase in post-vaccination reciprocal titer against A/Indonesia/5/05 virus 21 days after the second dose of Influenza A (H5N1) Virus Monovalent Vaccine, Adjuvanted.
Measured: At Day 42 post Dose 1 (Day 42 post Dose 1 = Day 21 post Dose 2)
Number of Seroprotected Subjects Against A/Indonesia/5/2005 (H5N1)
A seroprotected subject was defined as a vaccinated subject with serum Hemagglutination Inhibition (HI) titer ≥ 1:40.
Measured: At Day 0 and Day 42 post Dose 1 (Day 42 post Dose 1 = Day 21 post Dose 2)
Number of Subjects With Any Solicited Local Symptoms.
Assessed solicited local symptoms were pain, redness and swelling. Any = occurrence of the symptom regardless of intensity grade.
Measured: During a 7-day follow-up period (i.e., day of vaccination and 6 subsequent days) after each vaccine administration
Number of Subjects With Any Solicited General Symptoms.
Assessed solicited general symptoms were fatigue, headache, joint pain at other locations, muscle aches, shivering, sweating and temperature[defined as axillary temperature equal to or above 37.5 degrees Celsius (°C)]. Any = occurrence of the symptom regardless of intensity grade.
Measured: During a 7-day follow-up period (i.e., day of vaccination and 6 subsequent days) after each vaccine administration
Number of Subjects With Any Unsolicited Adverse Events (AEs).
An unsolicited AE covers any untoward medical occurrence in a clinical investigation subject temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product and reported in addition to those solicited during the clinical study and any solicited symptom with onset outside the specified period of follow-up for solicited symptoms. Any was defined as the occurrence of any unsolicited AE regardless of intensity grade or relation to vaccination.
Measured: During a 21-day follow-up period for each vaccine administration, as well as overall (Day 0 through Day 84)
Number of Subjects With Serious Adverse Events (SAEs)
Serious adverse events (SAEs) assessed include medical occurrences that result in death, are life threatening, require hospitalization or prolongation of hospitalization or result in disability/incapacity.

A Phase 3 study testing Influenza A (H5N1) Virus Monovalent Vaccine, Adjuvanted in people with Influenza, run by GlaxoSmithKline at 40 sites in 2 countries.
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 6 inclusion and 15 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 Jun 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 40 sites in United States, Canada. 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. Some participants in this study may receive a placebo. 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?
Yes. Results are posted in the registry (first posted 7 Feb 2014). 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 Seroconverted Subjects Against A/Indonesia/5/2005 (H5N1) (time frame: At Day 42 post Dose 1 (Day 42 post Dose 1 = Day 21 post Dose 2)). The study lists 7 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 NCT00616928, which also lists 1 linked publication.
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 Jun 2018.
