About this study
Official title: A Single Center, Open-Label, Phase I/II Study of Two 90-µg Doses of Intramuscular Inactivated Influenza A/H5N1 Vaccine in Healthy Adult Subjects
The purpose of this study is to see how antibodies (proteins that fight infection) are made after you receive the new H5N1 flu vaccine. The new H5N1 vaccine will be given to 50 healthy adult lab workers, aged 18 years and older. Subjects will receive two 90mcg injections (shots in the arm) of the vaccine about 1 month apart. Subjects will maintain a memory aid to record oral temperature and any response to the vaccine for 7 days after each immunization. Subjects will be contacted by telephone 1 to 3 days after vaccination. They will return to the clinic on Day 7. Blood will be drawn before each vaccination and on Days 56 and 180. Subjects may be involved in the study for about 6 months. It is anticipated that the vaccine will provide safe protection against influenza H5N1.
Read the detailed description
The purpose of this open-label, phase I/II study is to investigate the safety and immunogenicity of two 90-mcg doses of intramuscular inactivated influenza A/H5N1 vaccine in healthy adults, aged 18 years and older. Subjects will receive 2 doses of the vaccine separated by approximately 28 days. Subjects will maintain a memory aid to record oral temperature and systemic and local adverse events (AEs) for 7 days after each immunization. Subjects will be contacted by telephone 1 to 3 days after vaccination (approximately Day 2) to assess concomitant medications and the occurrence of AEs, and they will return to the clinic on Day 7 for AE and concomitant medication assessment, a targeted physical examination (if indicated), and review of the memory aid. Serum for immunogenicity evaluations will be obtained prior to the first vaccination (Day 0) and prior to the second vaccination (at Day 28), and on Days 56 and 180. Primary objectives are to determine the safety of subvirion inactivated A/H5N1 vaccine in healthy adults and to determine the immunogenicity of subvirion inactivated H5N1 vaccine in healthy adults approximately 1 month following receipt of each of two 90 mcg doses of vaccine. The secondary objective is to evaluate immunogenicity and the percent of subjects responding approximately 1 and 7 months after the first vaccination. Primary endpoints are: AE or serious adverse event information (solicited in-clinic and via memory aids, concomitant medications, and periodic targeted physical assessment); geometric mean titer (GMT) and frequency of 4-fold or greater increases in neutralizing antibody titers 28 days after receipt of second dose of the vaccine; and GMT and frequency of 4-fold or greater increases in serum hemagglutination inhibition (HAI) antibody titers against the influenza A/H5N1 virus 28 days after receipt of the second dose of the vaccine. The secondary endpoints are GMT and frequency of 4-fold or greater increases in neutralizing antibody titers in each group 1 month and 7 months after receipt of the first dose of vaccine; GMT and frequency of 4-fold or greater increases in serum hemagglutination inhibition (HAI) antibody titers in each group 1 month and 7 months after receipt of the first dose of vaccine; and development of serum antibody responses against antigenically drifted variants of H5N1 influenza viruses.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Inactivated Influenza A/H5N1 Vaccine (sanofi pasteur) 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 6 inclusion and 10 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 27 Aug 2010. 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 combined 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.
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?
Adverse event (AE) or serious AE information (solicited in-clinic and via memory aids, concomitant medications, and periodic targeted physical assessment). (time frame: 1 - 3 days after each vaccination to review any AEs and SAEs; approximately 1 week after each vaccination review any AEs and collect for 28 days following the 2nd dose of vaccine. SAEs will be collected throughout the study through day 180.). 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?
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 27 Aug 2010.
