Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Unknown

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

  1. Part 1 If study subject's legal guardians who decide voluntarily to participate the clinical trial, and sign the Informed Consent Form, study subjects eligible for participating this trial protocol were assigned to test group and receiving the test drug 1 time or 2 times.
  2. Part 2 If study subject's legal guardians who decide voluntarily to participate the clinical trial, and sign the Informed Consent Formed, study subjects eligible for participating this trial protocol were assigned to test group or control group with the ratio of 4:1 and receiving the test or control drug 1 time or 2 times.

The investigator will evaluate the efficacy and safety of the test product while clinical trial.

Blood samples will be collected at visit 1 and visit 5 for immunogenicity evaluation. The study subject and their legal guardians will be educated to daily record AEs after vaccination on the patient diary to evaluate the safety.

At visit1, blood samples will be collected from randomized study subjects and investigational drug will be intramuscularly injected. However, those who had not been vaccinated with influenza vaccine, will re-visit and have the 2nd vaccination, 4~5 weeks after the 1st vaccination.

After 4~5 weeks since last vaccination, study subjects will visit and blood sample will be collected. And the serious adverse events occurred during 180 days after the final vaccination will be checked through the telephone visit.

The study subjects with 1 dose of vaccine will have 4 visits including Visit 1~2 and Visit 5~6. The study subjects with 2 dose of vaccine will have 6 visits including Visit 3~4.

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.

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
Seroconversion rate for HI antibody after final injection
Time Frame: Post-vaccination (Day 28 or 56)
the percentage of study subjects with a pre-vaccination (Day 0) HI titer<1:10 and post-vaccination (Day 28) HI antibody titer≥1:40(Case1), or the percentage of study subjects with a pre-vaccination HI antibody titer≥1:10 and a minimum four-fold rise in post-vaccination HI antibody titer(Case 2)
Post-vaccination (Day 28 or 56)
Seroprotection rate for HI antibody after final injection
Time Frame: Post-vaccination (Day 28 or 56)
Post-vaccination (Day 28 or 56)

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
GMT
Time Frame: Post-vaccination (Day 28 or 56)
GMT(Geometric Mean Titer) of HI antibody titer before vaccination(Day 0) and after vaccination (Day 28)
Post-vaccination (Day 28 or 56)
GMR
Time Frame: Post-vaccination (Day 28 or 56)
GMR(Geometric Mean Ratio) of HI antibody titer before vaccination(Day 0) and after vaccination (Day 28)
