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

No

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
Seroprotection
Time Frame: Day 22 +/- 2 days
Seroprotection rate, defined as proportion of subjects with HI antibody titer ≥1:40 (The primary endpoints are the immunogenicity parameters for HA assessed via hemagglutinin inhibition method (HI). These parameters were analyzed according to the EMA "Note for guidance on harmonisation of requirements for influenza vaccines," 1997)
Day 22 +/- 2 days
Seroconversion
Time Frame: Day 22 +/- 2 days
Seroconversion rate, defined as proportion of subjects with ≥4-fold increase in HI antibody titer and with a titer of ≥1:40 (The primary endpoints are the immunogenicity parameters for HA assessed via hemagglutinin inhibition method (HI). These parameters were analyzed according to the EMA "Note for guidance on harmonisation of requirements for influenza vaccines," 1997)
Day 22 +/- 2 days
Geometric Mean Titer
Time Frame: Day 22 +/- 2 days
GMT of HI antibodies and fold-increase in GMT (The primary endpoints are the immunogenicity parameters for HA assessed via hemagglutinin inhibition method (HI). These parameters were analyzed according to the EMA "Note for guidance on harmonisation of requirements for influenza vaccines," 1997)
Day 22 +/- 2 days

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
Number of Participants With Local and Systemic Adverse Events, as a Measure of Safety and Tolerability
Time Frame: Baseline (Day 1) and 3 weeks after vaccination (Day 22 ± 2 days)

Solicited local and systemic AEs, Unsolicited AEs

Unsolicited AEs were collected from baseline (Day 1) to 3 weeks after vaccination (Day 22 ± 2 days).

Solicited local and systemic AEs were collected by subjects diary from Day 1 (day of vaccination) to Day 4
Baseline (Day 1) and 3 weeks after vaccination (Day 22 ± 2 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.
