About this study

Official title: Randomized, Parallel-group, Double-blind, Single-center Phase III Study to Assess the Immunogenicity and Safety of the 2011/2012-season Influenza Vaccine Formulated With HA Antigen From Two Suppliers, in Elderly and Young Adult Subjects Using the Current EMA Regulations as Guideline

What is being measured

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

  1. Geometric Mean Titer

    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)

    Measured: 3 weeks after vaccination (Day 22 ± 2 days)

  2. Seroprotection

    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)

    Measured: 3 weeks after vaccination (Day 22 ± 2 days)

  3. Seroconversion

    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)

    Measured: 3 weeks after vaccination (Day 22 ± 2 days)

Secondary outcomes (1)
  1. Number of Participants With Local and Systemic Adverse Events, as a Measure of Safety and Tolerability

    Solicited local and systemic AEs, Unsolicited AEs, Tolerability and acceptability

    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

    Measured: Baseline (Day 1) and 3 weeks after vaccination (Day 22 ± 2 days)

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Virosomal influenza vaccine (AdImmune HA Antigen) and Virosomal influenza vaccine (CSL HA Antigen) in people with Influenza, run by Crucell Holland BV at 1 site in Switzerland.

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 3 inclusion and 15 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 9 Sep 2013. 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 Switzerland. 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?

Yes. Results are posted in the registry (first posted 22 Mar 2013). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Geometric Mean Titer (time frame: 3 weeks after vaccination (Day 22 ± 2 days)). The study lists 3 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 9 Sep 2013.
