Study groupRoleWhat they receive
GSK1247446A GroupExperimentalSubjects aged between 18 and 60 years, having previously received one dose of the AS03-adjuvanted GSK1247446A vaccine in the primary study NCT00374842, received a single dose of GSK1247446A vaccine adjuvanted with a half dose of AS03 adjuvant at Day 0 of the current follow-up study NCT00545025. The vaccine was administered intramuscularly, in the deltoid region of the non-dominant arm. Subjects in this group originated from either the GSK1247446A Formulation 1 or GSK1247446A Formulation 2 groups in study NCT00374862.
Receives: Biological: Influenza Vaccine GSK1247446A
Fluarix GroupActive comparatorSubjects aged between 18 and 60 years, having previously received one dose of Fluarix™ vaccine during the primary study NCT00374842, received one dose of Fluarix™ vaccine at Day 0 of the current follow-up study NCT00545025. The vaccine was administered intramuscularly, in the deltiod region of the non-dominant arm. Subjects in this group originated from the Fluarix Group in study NCT00374862.

What is being measured

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

  1. Number of Subjects With Any, Grade 3 and Related Solicited Local Symptoms

    Assessed solicited local symptoms were ecchymosis, pain, redness and swelling at injection site. Any = incidence of a particular symptom regardless of intensity grade. Grade 3 pain = pain that prevented normal everyday activity. Grade 3 redness/swelling/ecchymosis = redness/swelling/ecchymosis spreading beyond 50 millimeters (mm) of the injection site. All solicited local symptoms assessed were considered by the investigator as related to study vaccination.

    Measured: During a 7-day (Days 0-6) follow-up period after re-vaccination

  2. Number of Subjects With Any, Grade 3 and Related Solicited General Symptoms.

    Assessed solicited general symptoms were arthralgia, fatigue, fever [oral temperature equal to or above ≥ 37.5 degrees Celsius (°C)], headache, myalgia, nausea and shivering. Any = incidence of a particular symptom regardless of grade intensity or relationship with the study vaccination. Grade 3 symptom = symptom that prevented normal activity. Grade 3 fever = fever > 39.0°C. Related = symptom considered by the investigator to have a causal relationship to study vaccination.

    Measured: During a 7-day (Days 0-6) follow-up after re-vaccination

  3. Number of Subjects With Any, Grade 3 and Related Unsolicited Adverse Events (AEs)

    Unsolicited AE covers any AE 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 = any unsolicited AE regardless of intensity or relationship to vaccination. Grade 3 = unsolicited AE that prevented normal activity. Related = unsolicited AE assessed by the investigator as causally related to the study vaccination.

    Measured: During a 30-day (Days 0-29) follow-up period after re-vaccination

  4. Number of Subjects With Any and Related 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, result in disability/incapacity or are a congenital anomaly/birth defect in the offspring of a study subject. Related = SAE assessed by the investigator as causally related to the study vaccination.

    Measured: During the entire study period (Days 0-30)

Secondary outcomes (4)
  1. Titers for Serum Hemagglutination Inhibition (HI) Antibodies Against 3 Strains of Influenza Disease.

    Titers are presented as geometric mean titers (GMTs). The 3 influenza strains assessed were A/Solomon Islands (A/SOL), A/Wisconsin (A/WIS) and B/Malaysia (B/MAL). The seropositivity cut-off assay was 1:10.

    Measured: At Days 0 and 21

  2. Number of Seroconverted Subjects Against 3 Strains of Influenza Disease.

    A seroconverted subject was defined as a vaccinated subject who had either a pre-vaccination titer <1:10 and a post-vaccination titer ≥1:40 or a pre-vaccination titer ≥1:10 and at least a four-fold increase in post-vaccination titer. The 3 influenza strains assessed were A/Solomon Islands (A/SOL), A/Wisconsin (A/WIS) and B/Malaysia (B/MAL).

    Measured: At Day 21

  3. Number of Seroprotected Subjects Against 3 Strains of Influenza Disease.

    A seroprotected subject was defined as a vaccinated subject who had a serum HI titer ≥ 1:40. The 3 influenza strains assessed were A/Solomon Islands (A/SOL), A/Wisconsin (A/WIS) and B/Malaysia (B/MAL).

    Measured: At Day 0 and 21

  4. Seroconversion Factor for HI Antibodies Against 3 Strains of Influenza Disease.

    The seroconversion factor (SCF) was defined as the fold increase in serum Hemagglutination Inhibition (HI) geometric mean titers (GMTs) post vaccination compared to Day 0. The 3 influenza strains assessed were A/Solomon Islands (A/SOL), A/Wisconsin (A/WIS) and B/Malaysia (B/MAL).

    Measured: At Day 21

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Influenza Vaccine GSK1247446A and Fluarix™ in people with Influenza and Influenza, Human, 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 5 inclusion and 12 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 26 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 May 2013). 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 Subjects With Any, Grade 3 and Related Solicited Local Symptoms (time frame: During a 7-day (Days 0-6) follow-up period after re-vaccination). The study lists 4 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 26 Jun 2019.
