About this study
Official title: Extent and Durability of Immune Response Following Seasonal Influenza Vaccination in Healthy Volunteers
This is an open-label, single administration dose study in adult healthy male and female subjects. After qualifying for the study, subjects will receive a single intramuscular injection of the FDA approved 2016-2017 quadrivalent influenza vaccine.
Read the detailed description
Subjects will be screened within 28 days prior to enrollment into the study. After qualifying for the study subjects will visit the clinical unit on Day l and will have pre-dose blood samples taken for humoral (serum) and cellular(peripheral blood mononuclear cells PBMCs) immunity testing and nasopharyngeal swabs for assessment of mucosa! immunity, and will then be given the vaccine.
Over the next 6 months, I 0-mL blood samples will be collected on Days 4, 8, 15, 29, 91 and 181 for HAI testing. Peripheral blood mononuclear cells will be collected on Day 8 to assess cellular responses. A nasopharyngeal swab will also be done on Day 29. Screening assessments will include clinical laboratory tests (hematology, chemistry, urinalysis (UA), drug and alcohol testing), vital signs, 12-lead electrocardiogram and physical examination.
Adverse events (AEs) will be monitored throughout the study.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Licensed seasonal influenza vaccine in people with Influenza, run by Altimmune, Inc. 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 7 inclusion and 32 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 26 Apr 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 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
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 26 Apr 2019). 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?
HAI Antibody Immune Response to Matched Influenza Strain H1N1 A/California/04/2009 Strain (time frame: Day 29 after vaccine). 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 26 Apr 2019.
