Any change that is due to change of health care provider, insurance company, etc, or is done for financial reasons, as long as in the same class of medication, will not be considered a violation of the inclusion criterion. Any change to prescription medication due to improvement of a disease outcome will not be considered a violation of the inclusion criterion.

About this study

Official title: Evaluation of the Safety and Cellular and Humoral Immune Response to Primary and Secondary Immunization With Subvirion H5N1 Vaccines Representing Different Clades

The purpose of the study is to evaluate safety and compare how the body reacts to 2 different strengths of the Clade (specific type of H5N1 virus) 2 H5N1 flu vaccine when given as a single vaccination with a high dose (90 mcg) or low dose (15 mcg) to volunteers who have received at least 2 doses of the Clade 1 H5N1 vaccine, in a previous National Institute of Health study or who have never received a H5N1 vaccine (naïve). Previously vaccinated subjects (in studies 04-0063, 05-0090, 05-0127) will receive either 15 or 90 mcg of H5N1 vaccine. Multiply boosted volunteers who participated study 05-0043 and received Clade 1 and 3 vaccines, will receive the same dose (15mcg). Vaccine naïve subjects will receive 2 doses of vaccine (15 or 90 mcg) separated by 28 days. Blood samples will be collected. 115 volunteers age 18-64 may participate in study related procedures for approximately 7 months.

Read the detailed description

In response to the steadily increasing number of reports of human infection with avian influenza A (H5N1) viruses, there is now a world-wide effort to develop and test potential candidate vaccines for this and other avian viruses with pandemic potential. The study will be conducted as a laboratory blinded assessment of the humoral and cellular immune response to A/Indonesia/5/05 vaccine in three populations: healthy adults who have previously received a clade 1 H5 vaccine in a Division of Microbiology and Infectious Diseases (DMID)-sponsored study; healthy adult recipients of prime-boost regimens representing two clades; and healthy adults with no previous H5 vaccination and who are not at risk for H5 exposures. Primed subjects are randomized to receive a single dose of either 15 mcg or 90 mcg of A/Indonesia/5/05 vaccine. Multiply boosted subjects are those who participated in study 05-0043, and have previously received both A/HK/97 (Clade 3) and A/VN/04 (Clade 1) vaccines. Because only a small number of such subjects are available, they will not be randomized but will all receive the same dose of vaccine. Unprimed subjects are randomized to receive 2 doses of 15 mcg or 90 mcg of A/Indonesia/5/05 vaccine separated by 28 days. In all groups, sera and peripheral blood mononuclear cells (PBMC) are obtained prior to and on days 3, 7, 14, and 28 after each dose. Primed and multiply boosted subjects also have sera and PBMC obtained on day 56. All groups will make a final study visit at 6 months following the last dose of vaccine (day 180 for primed and boosted subjects and day 208 for unprimed subjects). Approximately 115 subjects between the ages of 18 and 64 will participate in this study. The primary objective is to determine the safety of administration of the A/Indonesia/05 subvirion vaccine when administered to healthy, primed or unprimed adults. The secondary objective is to: determine the effects of priming with a clade 1 vaccine on antibody responses to revaccination with a clade 2 vaccine. The tertiary objectives are to determine the effects of priming on the repertoire and phenotypes of B and T cells generated in response to vaccination; to evaluate whether pre-existing immunity to seasonal influenza viruses impacts the specificity and magnitude of the cluster of differentiation marker (CD)4 T cell response to H5 vaccination and to describe the kinetics of the cellualr immune response to subvirion H5N1 vaccinatin in primed and unprimed individuals. The primary endpoint is reactogenicity, adverse event (AE) and serious adverse event (SAE) information, solicited in-clinic and via memory aids. The secondary endpoints are: levels of HAI antibody recognizing A/Indonesia/05 (Clade 2), A/Vietnam/04 (Clade 1) and representative Clade 2 subclade viruses, and levels of neutralizing antibody assessed by neutralization tests using the rgA/Indonesia/5/05 virus prior to and Days 3, 7, 14, and 28 after each vaccination. This study is linked to DMID protocols 04-063, 05-0090, 05-0043 and 05-0127.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Influenza Virus Vaccine, Monovalent A/H5N1 A/Indonesia/05/2005 in people with Influenza, run by National Institute of Allergy and Infectious Diseases (NIAID) at 1 site in United States.

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 9 inclusion and 20 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 1 Jan 2016. 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 United States. 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?

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?

Reactogenicity: Occurrence of vaccine-associated unsolicited adverse events through Day 28 after the last vaccination (time frame: Day 0 to Day 28 for primed and boosted subjects and Day 0 to Day 56 for unprimed subjects.). 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?

On the ClinicalTrials.gov record for NCT01086566.

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 1 Jan 2016; AzTrials last refreshed its copy on 7 Nov 2026.
