About this study
This is an open study of the use of AdimFlu-V (2012-2013 season) vaccine in young healthy subjects. Subjects aged equal to or over 9 years old and less than 18 years old will receive one dose of vaccine (0.5 mL) by intramuscular injection into the upper arm. Subjects aged equal to or over 3 years old and less than 9 years old will received two doses of vaccine (0.5 mL) by intramuscular injection into the upper arm separated by 4 weeks (28 days). Safety outcomes included immediate reactions at the time of vaccination, solicited local and systemic reactions within 7 days after each vaccination, unsolicited adverse events observed since first vaccination to 28 days after the last dose of vaccination, and serious adverse events during the observation. Sera prepared from blood samples will be collected from each subject immediately prior to, and 4 weeks after each vaccination. Anti-hemagglutinin (HA) antibody titers will be determined using the WHO hemagglutination inhibition reference technique. The central laboratory who is responsible for antibody titrations will not be aware of the background of blood samples (e.g., pre- or post-serum), it is also called observer-blinded. All subjects will be followed, either by clinical visit or by telephone contact, for 8 weeks after the last vaccination for safety reasons.

What is being measured
The primary outcome is the main question the study is designed to answer.
The primary objective is to evaluate the immunogenicity profiles for influenza virus vaccine strains (2012-2013 season) of the AdimFlu-V.
Serum samples will be obtained prior to vaccination, and 4 weeks post each vaccination. Serum samples will be tested for anti-hemagglutinin (HA) antibodies by hemagglutination inhibition (HAI) and assays will be performed at Adimmune Corporation designated central laboratory. Subjects will be considered to be seronegative if serum HAI titer < 1:10. The seroconversion is defined as the post-vaccination serum HAI titer at least 1:40 for whom had negative pre-vaccination or a four-fold or greater increase in HAI titers in subjects who had positive pre-vaccination serum.
Measured: Change from baseline for anti-hemaglutinin (HA) antibodies by hemagglutinaton inhibition (HAI) at 28 days post immunization
Secondary outcomes (1)
The secondary objective is to evaluate the safety and tolerability profiles including the presence or absence of the pre-specified reactogenicity events and other serious/non-serious adverse events of the AdimFlu-V.
Reactogenicity events are pre-specified adverse events systematically recorded on diary cards (a grid of check boxes for each event and each day) during the immediate post-vaccination period by all participants. In general, reactogenicity events will be recorded for 7 days after each vaccination. The selection of the events to be collected systematically is based on events expected to occur with wild-type influenza infection including fever (≥38°C), runny nose or nasal congestion, cough, sore throat, muscle aches, headache, vomiting, nausea and malaise. Furthermore, the local (injection site) reactions will also be evaluated that include soreness/pain, swelling, redness, ecchymosis and limitation of arm motion.
In regard to the long term safety of the study vaccine, the significant and/or serious adverse event(s) will be recorded during the 8 weeks follow up after the scheduled last vaccination.
Measured: 7 days of each vaccination and 8 weeks after last vaccination

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing AdimFlu-V in people with Influenza, run by Adimmune Corporation at 1 site in Taiwan.
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 4 inclusion and 13 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 16 Jul 2018. 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 Taiwan. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
The primary objective is to evaluate the immunogenicity profiles for influenza virus vaccine strains (2012-2013 season) of the AdimFlu-V. (time frame: Change from baseline for anti-hemaglutinin (HA) antibodies by hemagglutinaton inhibition (HAI) at 28 days post immunization). 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 16 Jul 2018.
