October 18, 2017 updated by: Seqirus

A Phase IV, Single-centre, Open-label Study to Evaluate the Immunogenicity and Safety of the 2010/2011 Formulation of Enzira® Vaccine in Two Groups of Healthy Volunteers: 'Adults' (Aged 18 to 59 Years) and 'Older Adults' (Aged 60 Years or Older)

The purpose of this study is to determine whether the 2010/2011 Formulation Enzira vaccine is safe and elicits an immune response to seasonal influenza in healthy adults.

Study Overview

Status

Status

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
The Percentage of Evaluable Participants Achieving Seroconversion or Significant Increase in Antibody Titre.
Time Frame: Approximately 21 days after vaccination
As per the criteria specified in the CPMP/BWP/214/96 Note for Guidance on Harmonisation of Requirements for Influenza Vaccines. For haemagglutination inhibition (HI), seroconversion is defined as achieving a post-vaccination titre of ≥ 40 for those participants with a pre-vaccination HI titre of < 10; significant increase is defined as a four-fold or greater increase in HI titre for those participants with a pre-vaccination HI titre of ≥ 10.
Approximately 21 days after vaccination
The Geometric Mean Fold Increase (GMFI) in Antibody Titre After Vaccination.
Time Frame: Approximately 21 days after vaccination
GMFI is defined as the geometric mean of the fold increases of post-vaccination antibody titre over the pre-vaccination antibody titre.
Approximately 21 days after vaccination
The Percentage of Evaluable Participants Achieving a HI Titre ≥ 40 or Single Radial Haemolysis (SRH) Area ≥ 25 mm2.
Time Frame: Approximately 21 days after vaccination
Approximately 21 days after vaccination

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Frequency of Any Solicited Adverse Events (AEs)
Time Frame: During the 4 days after vaccination (Day 0 plus 3 days)
The number of participants reporting any solicited AEs.
During the 4 days after vaccination (Day 0 plus 3 days)
Frequency and Intensity of Any Unsolicited Adverse Events
Time Frame: After vaccination until the end of the study; approximately 21 days

Unsolicited adverse event (UAE) grading:

Mild: Symptoms were easily tolerated and there was no interference with daily activities. Moderate: Enough discomfort to have caused some interference with daily activities. Severe: Symptoms that prevented normal, everyday activities.
After vaccination until the end of the study; approximately 21 days

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit).
