This outcome included only subjects who received two doses of the study product and results were tabulated per age stratum. The CHMP criterion was fulfilled if the post-vaccination point estimate for SPR was > 70% in subjects 18 to 60 of age or > 60% for subjects above 60 years of age .
Number of Subjects Who Were Seroprotected (SPR) for HI Antibodies Against the Flu A/California/7/2009 (H1N1) Virus Strain
Time frame: At Day 21
A seroprotected subject was defined as a vaccinated subject with a serum HI titer greater than or equal to (≥) 1:40, that usually is accepted as indicating protection. This outcome included only subjects who received two doses of the study product and the results were tabulated per age stratum. The CHMP criterion was fulfilled if the post-vaccination point estimate for SPR was > 70% in subjects 18 to 60 of age or > 60% for subjects above 60 years of age .
Geometric Mean Fold Rise (GMFR) for HI Antibodies Against Flu A/CAL/7/09 Strain of Influenza Disease
Time frame: At Day 21
GMFR was defined as the fold change in serum HI geometric mean titers (GMTs) post-vaccination compared to pre-vaccination. The flu strain assessed was Flu A/CAL/7/09. This outcome included only subjects who received two doses of the study product and results were tabulated per age stratum. The CHMP criterion was fulfilled if the point estimated for GMFR was > 2.5 in subjects 18 to 60 years old or > 2 for subjects > 60 years of age.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing GSK investigational vaccine GSK2340272A 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 10 inclusion and 18 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 Jun 2019. 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 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 18 Sep 2018). 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 (SCR) Subjects for Hemagglutination Inhibition (HI) Antibodies (time frame: At Day 21). The study lists 3 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 NCT00968526, 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 Jun 2019; AzTrials last refreshed its copy on 8 Nov 2026.
