What is being measured

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

  1. The Percentages Of Subjects Achieving Hemagglutination Inhibition (HI) Titers ≥40 Against A/H5N1 Strain.

    The optimal aH5N1c vaccine formulation was evaluated in terms of percentages of subjects achieving HI titers ≥40 against homologous A/H5N1 strain, three weeks after second vaccination with either low dose or high dose of aH5N1c vaccine, according to the Center for Biologics Evaluation and Research (CBER) criterion.

    The CBER criterion for the elderly population is met if the lower limit of the two-sided 95% confidence interval (CI) for the percentages of subjects achieving HI titer ≥40 meets or exceeds 60%.

    Measured: Baseline (day 1) and Three weeks after 2nd vaccination (day 43)

  2. The Percentages Of Subjects Achieving Seroconversion Against A/H5N1 Strain.

    Immunogenicity was measured in terms of the percentages of subjects achieving seroconversion or significant increase in HI titer against the vaccine strain, three weeks after receiving two injections of low dose or high dose of aH5N1c vaccine according to the CBER criterion.

    Seroconversion is defined as, a postvaccination titer ≥40 in subjects with a prevaccination HI titer <10; or in subjects with prevaccination HI titer ≥10, a minimum four-fold rise in postvaccination HI antibody titer.

    The CBER criterion for the elderly population is met if the lower limit of the two-sided 95% CI for the percentages of subjects achieving seroconversion for HI antibody titer meets or exceeds 30%.

    Measured: Three weeks after 2nd vaccination (day 43)

  3. Number of Subjects Reporting Solicited Local and Systemic Adverse Events, After Any Vaccination.

    Safety was assessed as the number of subjects who reported solicited local and systemic adverse events following vaccination with either low or high dose of aH5N1c vaccine.

    Measured: From day 1 through day 7 after any vaccination.

  4. Number of Subjects Reporting Unsolicited Adverse Events After Any Vaccination.

    Safety was assessed using the number of subjects who reported any unsolicited adverse events, adverse events possibly or probably related to study vaccine, serious adverse events (SAEs), new onset of chronic diseases (NOCDs), medically attended AEs, AEs of special interest (AESIs), AEs leading to withdrawal from study following vaccination with aH5N1c vaccine

    Measured: Day 1 through day 387 after any vaccination

Secondary outcomes (3)
  1. Geometric Mean Ratios (GMR) Against A/H5N1 Strain Following 2-dose Vaccination Schedule of Either Low Dose or High Dose aH5N1c Vaccine.

    Immunogenicity was measured as the GMR. The ratio of postvaccination to prevaccination HI geometric mean titers (GMTs) is reported.

    The criterion is met according to the European Committee for Medicinal Products for Human Use (CHMP) criterion if the geometric mean increase GMR (day 43/day 1) in HI antibody titer is >2.0 for subjects >60 years of age.

    Measured: Day 1; day 22; day 43 and day 387

  2. Percentages Of Subjects With HI Titers ≥40 Against A/H5N1 Strain

    Immunogenicity was assessed in terms of percentage of subjects achieving HI titers >40, three weeks after second vaccination with aH5N1c according to the CHMP criterion.

    The European Licensure (CHMP) criterion is met if the percentage of subjects achieving HI titers ≥40 is >60%.

    Measured: Day 1, day 22, day 43 and day 387.

  3. The Percentages Of Subjects Achieving Seroconversion Against A/H5N1 Strain

    Immunogenicity was assessed in terms of percentages of subjects achieving seroconversion in HI titers, three weeks after receiving two injections of either low dose or high dose aH5N1c vaccine according to the CHMP criterion.

    Seroconversion is defined as a postvaccination titer ≥40 in subjects with a prevaccination HI titer <10; or in subjects with prevaccination HI titer ≥10, a minimum four-fold rise in postvaccination HI antibody titer.

    The criterion is met according to the European (CHMP) guideline if the percentage of subjects achieving seroconversion is >30%.

    Measured: Day 22, day 43 and day 387

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Adjuvanted H5N1 pandemic influenza vaccine in people with Pandemic H5N1 Influenza, run by Novartis Vaccines at 23 sites in 4 countries.

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 18 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 30 Jan 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 23 sites in United States, Australia, Thailand, New Zealand. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 10 Aug 2015). 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?

The Percentages Of Subjects Achieving Hemagglutination Inhibition (HI) Titers ≥40 Against A/H5N1 Strain. (time frame: Baseline (day 1) and Three weeks after 2nd vaccination (day 43)). 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?

On the ClinicalTrials.gov record for NCT01766921, which also lists 1 linked publication.

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?
