Completed

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.

Detailed Description

This is a double-blind and randomized study in healthy adults. The duration of study will be approximately 90 days per participant. The study will include 4 visits: Day 1 (for vaccination), Day 4, Day 22 and day 90 (Follow-up visits). Safety and tolerability will be assessed by the rate of solicited, unsolicited, and serious adverse events.

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 to 49 years (Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

Exclusion Criteria:

  • Vaccination with 2013/2014-seasonal influenza vaccine and/or receipt of any vaccine in the 4 weeks preceding receipt of study vaccine and/or any vaccination planned within 3 weeks from the study vaccine
  • Diagnosis (by rapid test, performed at clinic/hospital laboratory) of laboratory-confirmed influenza in the 2013/2014 season
  • Acute exacerbation of bronchopulmonary infection (cough, sputum, lung findings) or other acute disease

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
Number of participants with Solicited Local Adverse Events (AEs)
Time Frame: Up to Day 8
The local AEs pain, erythema, and induration at the study vaccine injection site will be noted in the participant Diary from Day 1 to Day 8. The extent (largest diameter) of any redness or induration should be measured daily and recorded, along with any functional limitation of activity. Local AEs will be graded according to severity as mild (Grade 1), moderate (Grade 2), severe (Grade 3) and potentially life threatening (Grade 4).
Up to Day 8
Number of participants with Solicited Systemic Adverse Events (AEs)
Time Frame: Up to Day 8
The solicited systemic AEs headache, fatigue, myalgia, malaise, and shivering/rigors will be noted in the participant Diary from Day 1 to Day 8. Fever (defined as body temperature greater than 38.0 Celsius) is another solicited systemic AE. Local AEs will be graded according to severity as mild (grade 1), moderate (grade 2), severe (grade 3) and potentially life threatening (grade 4).
Up to Day 8
Number of participants with Unsolicited Adverse Events (AEs)
Time Frame: Up to Day 22
Unsolicited AEs are all AEs the participants are not specifically asked about in the participant Diary.
Up to Day 22
Number of participants with Serious Adverse Events (SAEs)
Time Frame: Up to Day 90
The SAE is a medical event that at any dose results in death, persistent or significant disability/incapacity, or drug dependency/abuse; is life-threatening, an important medical event, or a congenital anomaly/birth defect; or requires or prolongs hospitalization or is a suspected transmission of any infectious agent via medicinal product.
Up to Day 90

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 Seroconversion
Time Frame: Day 22
Number of participants with seroconversion will be the participants with a greater than or equal to (>=) 4-fold increase in hemagglutination inhibition (HI) antibody titer and a titer of >=1:40 at Day 22. HI against homologous strains will be measured with the HI test in serum.
Day 22
Number of Participants with Seroprotection
Time Frame: Baseline and Day 22
Number of participants with seroprotection is defined as number of participants with HI antibody >=1:40 at Day 22. HI against homologous strains will be measured with the HI test in serum.
Baseline and Day 22
Change From Baseline in Geometric Mean Titer (GMT) of HI antibodies
Time Frame: Baseline and Day 22
GMT and increase in GMT of HI antibodies from Baseline to Day 22 will be assessed.
Baseline and Day 22
