About this study
Official title: Preparing for an Influenza Pandemic: A Phase I Study of a Parenterally Administered H5N1 Influenza Vaccine in Healthy Adults
The safety and tolerability of the pandemic A/H5N1 virosomal vaccine formulated with or without the 3rd generation ISCOM™ adjuvant for parenteral administration will be investigated locally and systemically and by using haematological, biochemical and immunological screening tests. The immunogenicity of the H5N1 vaccine will be assessed through the induction of local and systemic antibody and cellular immune responses. In a pandemic situation, an important aspect is the rapidity of the immune response to the H5N1 vaccine so the detailed kinetics of the immune response will be investigated. The capacity of the vaccine to elicit long lasting immunity and cross reactive immunity to H5 viruses will also be evaluated. Furthermore, the quality of the immune response induced by the vaccine will be studied. The vaccine will be administered as twice the normal human dose (30μg HA) with and without adjuvant, and in a dose sparing manor of half (7.5μg HA) and one tenth (1.5μg HA) of the normal human dose with adjuvant. Sixty subjects will receive two doses of virosomal H5N1 influenza vaccine (separated by 21 ± 4 days) by intramuscular injection into the deltoid muscle. Escalating doses will be separated by a period of one week. Four groups each containing 15 subjects will receive two doses of the pandemic virosomal A/H5N1 influenza vaccine containing:
Group 1 30µg HA IM, Group 2 1.5µg HA adjuvanted with 50µg 3rd generation ISCOM™ IM, Group 3 7.5µg HA adjuvanted with 50µg 3rd generation ISCOM™ IM, Group 4 30µg HA adjuvanted with 50µg 3rd generation ISCOM™ IM.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The safety and tolerability of the pandemic A/H5N1 virosomal vaccine formulated with or without the 3rd generation ISCOM™ adjuvant for parenteral administration will be investigated locally and systemically and by using haematological, biochemical and immunological screening tests. The immunogenicity of the H5N1 vaccine will be assessed through the induction of local and systemic antibody and cellular immune responses. In a pandemic situation, an important aspect is the rapidity of the immune response to the H5N1 vaccine so the detailed kinetics of the immune response will be investigated. The capacity of the vaccine to elicit long lasting immunity and cross reactive immunity to H5 viruses will also be evaluated. Furthermore, the quality of the immune response induced by the vaccine will be studied. The vaccine will be administered as twice the normal human dose (30μg HA) with and without adjuvant, and in a dose sparing manor of half (7.5μg HA) and one tenth (1.5μg HA) of the normal human dose with adjuvant. Sixty subjects will receive two doses of virosomal H5N1 influenza vaccine (separated by 21 ± 4 days) by intramuscular injection into the deltoid muscle. Escalating doses will be separated by a period of one week. Four groups each containing 15 subjects will receive two doses of the pandemic virosomal A/H5N1 influenza vaccine containing:
Group 1 30µg HA IM, Group 2 1.5µg HA adjuvanted with 50µg 3rd generation ISCOM™ IM, Group 3 7.5µg HA adjuvanted with 50µg 3rd generation ISCOM™ IM, Group 4 30µg HA adjuvanted with 50µg 3rd generation ISCOM™ IM.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Influenza vaccine in people with Influenza and Healthy, run by Rebecca Cox at 1 site in Norway.
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 6 inclusion and 12 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 18 Nov 2019. 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 Norway. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
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 13 Dec 2016). 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?
Solicted Adverse Events (time frame: three months). 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?
On the ClinicalTrials.gov record for NCT00868218, which also lists 6 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 18 Nov 2019.
