What is being measured

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

  1. Geometric Mean Titers (GMT) After 1 Dose of Cell Culture Derived Vaccine (cTIV).

    Pre and postvaccination geometric mean titers against all 3 strains were assessed by hemagglutination inhibition (HI) assay using egg derived antigen in adults and elderly subjects.

    Measured: 3 weeks postvaccination (Day 22)

  2. Geometric Mean Ratio After 1 Dose of the Cell Culture Derived Vaccine (cTIV)

    Geometric mean ratio (GMR) of Day 22 / Day 1 geometric mean antibody titers was assessed by hemagglutination inhibition (HI)assay using egg derived antigen in adults and elderly subjects.

    The criterion is met according to European (CHMP) guideline if the mean geometric increase GMR (Day22 / Day1) in HI antibody titer is >2.5 for adults and >2.0 for elderly subjects.

    Measured: 3 weeks postvaccination (Day 22)

  3. Percentages of Subjects With HI Titer ≥40 After 1 Dose of Cell Culture Derived Vaccine (cTIV).

    HI titer as assessed by hemagglutination inhibition (HI) assay using egg derived antigen in adults and elderly subjects.

    This criterion is met according to European (CHMP) guideline if the percentages of subjects achieving HI titers ≥40 is >70% for adults and >60% for elderly subjects.

    Measured: 3 weeks postvaccination (Day 22)

  4. Percentages of Subjects With Seroconversion or Significant Increase After 1 Dose of Cell Culture Derived Vaccine (cTIV).

    Proportion of subjects with either seroconversion (antibody increase from < 10 pre vaccination to ≥40 post vaccination) or significant increase (antibody titer of ≥10 pre vaccination and 4-fold antibody increase post vaccination).

    According to the CHMP criteria, the percentages of subjects achieving seroconversion or significant increase should be >40% for adults and >30% for elderly subjects.

    Measured: 3 weeks postvaccination (Day 22)

Secondary outcomes (1)
  1. Number of Subjects Reporting Local and Systemic Reactions

    To evaluate the safety and tolerability of cell culture derived vaccine (cTIV) in adults and elderly subjects in terms of number of subjects reporting local and systemic reactions after 1 vaccine dose.

    Measured: 3 days postvaccination

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing cTIV in people with Seasonal Influenza Vaccine, run by Novartis Vaccines at 2 sites in Germany.

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 7 inclusion and 26 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 24 Jan 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Germany. 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 17 Jan 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 Titers (GMT) After 1 Dose of Cell Culture Derived Vaccine (cTIV). (time frame: 3 weeks postvaccination (Day 22)). The study lists 4 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 24 Jan 2013.
