About this study
Official title: A Randomized, Double-Blinded, Controlled, Phase I Study in Healthy Adults to Assess the Safety, Reactogenicity, and Immunogenicity of Intramuscular Subvirion Inactivated Monovalent Influenza A/H5N1 Virus Vaccine Administered With and Without AS03 Adjuvant: Standard & Systems Biology Analyses
This is a single center, randomized, double-blinded, controlled, Phase I, small targeted prospective study in healthy male and non-pregnant female subjects, 18 to 49 years old, inclusive, designed to determine the safety, reactogenicity, and immunogenicity of an intramuscular subvirion inactivated monovalent influenza A/H5N1 (HA of A/Indonesia/05/2005) virus vaccine manufactured by Sanofi Pasteur administered at 3.75 mcg per dose given with or without AS03 adjuvant manufactured by GSK. In the study, each subject will receive two doses administered 28 days apart. This study will use a systems biology approach to assess the human early gene and protein signatures expressed at Days 1, 3, 7, and 28 after the first vaccination. The systems data will be integrated with immunogenicity and reactogenicity data to develop a systems model of the human immune response to A/H5N1 vaccine with or without AS03 adjuvant.
Read the detailed description
The long term goals of this project are to identify RNA or protein biomarkers within 1 to 7 days after vaccination in peripheral blood that will predict a successful immune response and protection against disease. Adjuvants are used to boost the response of vaccines by stimulating the innate immune response. However, the exact mechanism and safety of adjuvants is still debated. Systems biology is the study of complex biological processes as integrated systems with many interacting components. The goal of systems biology is to make biology more predictive. This proposal will use a systems biology approach to identify successful immunization biomarkers. The study will use fresh blood samples and patient data collected in the proposed VTEU-funded study. At selected time points, volunteers' blood samples will be collected and immediately processed. Using these specimens, we will identify and quantify changes in the whole transcriptome and proteome of the major immune cells to identify and quantify changes in gene expression. We will integrate the changes in gene expression with the changes in the immune cells response. We will use mathematical modeling of the accumulated data to identify RNA or protein biomarkers that significantly correlate with the observed serum hemagglutination inhibition assay (HAI) response,cytokine/chemokine response, and cell mediated immunity (CMI) responses. Ultimately, the predictive biomarkers will be the foundation for a simple, rapid, inexpensive test to quickly show protection against a pathogen or foreign agent after vaccination. This is a single center, randomized, double-blinded, controlled, Phase I, small targeted prospective study in healthy male and non-pregnant female subjects, 18 to 49 years old, inclusive, designed to determine the safety, reactogenicity, and immunogenicity of an intramuscular subvirion inactivated monovalent influenza A/H5N1 (HA of A/Indonesia/05/2005) virus vaccine manufactured by Sanofi Pasteur administered at 3.75 mcg per dose given with or without AS03 adjuvant manufactured by GSK. In the study, each subject will receive two doses administered 28 days apart.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing ASO3 Adjuvant and Influenza A/H5N1 Vaccine 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 25 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 21 Oct 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 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?
GMT of neutralizing antibody, proportion of subjects achieving a serum neutralizing antibody titer of 1:40 or greater, and frequency of 4-fold or greater increases of neutralizing antibodies in each group against the subvirion inactivated A/H5N1 virus (time frame: Approximately Days:1, 3, 7 and 28, after receipt of the first dose of vaccine.). The study lists 4 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 NCT01573312, which also lists 2 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 21 Oct 2019.
