What is being measured

The primary outcome is the main question the study is designed to answer.

  1. seroconversion rate of hemoagglutination inhibition (HI) antibody titer

    evaluated for A/H1N1, A/H3N2, and B

    Measured: Day 29

  2. geometric mean titer (GMT) of HI antibody titer

    evaluated for A/H1N1, A/H3N2, and B

    Measured: Day 29

Secondary outcomes (6)
  1. seroprotection rate of HI antibody titer

    evaluated for A/H1N1, A/H3N2, and B

    Measured: Day 29

  2. GMT ratio of HI antibody titer

    evaluated for A/H1N1, A/H3N2, and B

    Measured: Day 1 and Day 29

  3. seroconversion rate of neutralizing antibody titer

    evaluated for A/H1N1, A/H3N2, and B

    Measured: Day 29

  4. seroprotection rate of neutralizing antibody titer

    evaluated for A/H1N1, A/H3N2, and B

    Measured: Day 29

  5. GMT of neutralizing antibody

    evaluated for A/H1N1, A/H3N2, and B

    Measured: Day 29

  6. GMT ratio of neutralizing antibody

    evaluated for A/H1N1, A/H3N2, and B

    Measured: Day 1 and Day 29

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing ASP7374 and approved egg-derived TIV in people with Influenza, run by UMN Pharma Inc. at 3 sites in Japan.

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 2 inclusion and 11 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 29 Sep 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in Japan. 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?

seroconversion rate of hemoagglutination inhibition (HI) antibody titer (time frame: Day 29). The study lists 2 primary outcomes in all. 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 29 Sep 2017.
