About this study
Official title: Phase 1 Inpatient Study of the Safety and Immunogenicity of One Dose of Live Influenza A Vaccine H7N3 (6-2) AA ca Recombinant (A/Chicken/British Columbia/CN-6/2004 x A/Ann Arbor/6/60 ca), a Live Attenuated Virus Vaccine Candidate for Prevention of Avian Influenza H7N3 Infection in the Event of a Pandemic
Over the past decade, avian influenza (AI) has become a major health concern. The development of safe and effective vaccines against avian strains that infect people is important. The purpose of this study is to determine the safety of and immune response of an investigational AI vaccine in healthy adults against the H7N3 strain of avian influenza.
Read the detailed description
The current pandemic risk associated with avian influenza H7N3 infection is significant, as an increasing number of humans are infected. H7 influenza transmission usually occurs in humans when they are exposed through direct contact to infected poultry or surfaces and objects contaminated by infected poultry feces. A pandemic occurs when a new influenza subtype emerges that infects humans, causes serious illness, and spreads easily between humans. The development of a safe and effective vaccine is necessary. The purpose of this study is to evaluate the safety and immunogenicity of a one-dose administration of the live, attenuated AI virus vaccine, H7N3 (6-2) AA ca Recombinant (A/chicken/British Columbia/CN-6/2004 x A/Ann Arbor/6/60 ca).
This study will last approximately 180 days. Participation in this study includes one 12-day hospital stay in an isolation unit at the University of Rochester Vaccine Evaluation Isolation Unit at St. Mary's Hospital in Rochester, NY. All participants will receive one dose of vaccine in nasal spray form at study entry. Participants will be admitted to the isolation unit 2 days prior to vaccination. A targeted physical exam, vital signs measurement, and nasal wash will occur daily following each vaccination until discharge. Participants will be discharged after two consecutive nasal washes on or after Day 7 are negative. Blood and urine collection will occur at selected timepoints throughout the study. Follow-up outpatient visits will occur approximately at Days 28, 56, and 180. A nasal wash and adverse events evaluation will occur at each follow-up visit.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Live Influenza A Vaccine H7N3 (6-2) AA ca Recombinant (A/chicken/British Columbia/CN-6/2004 x A/Ann Arbor/6/60 ca) in people with Influenza and Virus Diseases, 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 3 inclusion and 27 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 3 Jan 2013. 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?
Frequency of vaccine-related reactogenicity events (time frame: During inpatient stage). 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 NCT00853255, which also lists 4 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 3 Jan 2013.
