What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • H5N1 Influenza VaccineBiological

    Two 0.5mL injections of H5N1 influenza vaccine containing 7.5μg of H5N1 antigen (A/Vietnam/1194/2004), administered 3 weeks apart, and one 0.5mL injection of H5N1 vaccine 12 months after the second dose, IM into the deltoid muscle (preferably of the non-dominant arm) or anterolateral thigh (depending on the muscle mass).

  • H5N1 Influenza VaccineBiological

    Two 0.25mL or 0.5mL injections of H5N1 influenza vaccine, administered 3 weeks apart, IM into the deltoid muscle (preferably of the non-dominant arm) or anterolateral thigh (depending on the muscle mass).

What is being measured

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

  1. safety and tolerability of, and magnitude of antibody responses to two 0.5mL intramuscular injections of an H5N1 influenza vaccineapart

    Measured: administered 3 weeks apart

Secondary outcomes (2)
  1. safety and tolerability of, and magnitude of antibodies to one booster dose with a H5N1

    Measured: 12 months after primary immunization

  2. safety profile of a H5N1 compared to a seasonal flu vaccinepersistence of specific antibodies

    Measured: 12 months after primary immunization

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing H5N1 Influenza Vaccine in people with Prophylaxis of Avian Influenza, run by Novartis Vaccines at 1 site in Finland.

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 1 inclusion and 4 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 Feb 2012. 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 Finland. 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?

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?

safety and tolerability of, and magnitude of antibody responses to two 0.5mL intramuscular injections of an H5N1 influenza vaccineapart (time frame: administered 3 weeks apart). 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 NCT00537524, which also lists 2 linked publications.

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 Feb 2012.
