About this study
Official title: A Phase 1, Randomized, Placebo-Controlled, Double-Blind, Safety, Reactogenicity, and Immunogenicity of Recombinant M2e Influenza-A Vaccine Candidate ACAM FLU-A) in Healthy Adults
This multi-center study will be conducted in the United States with up to 80 healthy adult subjects. Subjects will be scheduled to receive a total of two (2) injections with 1 injection each administered.
Subjects will be randomized according to a randomization scheme.
Read the detailed description
All subjects will be followed up for 60 days post-randomization and through the influenza season. Following the influenza season, a subset of the subjects will receive a booster vaccine at the 12 month time point. The subjects will further be assessed at 2 days, 7 days, 15 days, 30 days and 6 months following the booster vaccination.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Influenza A Vaccine: ACAM FLU-A in people with Influenza, run by Sanofi at 3 sites 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 1 inclusion and 4 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 19 Jan 2012. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 3 sites 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. Some participants in this study may receive a placebo. 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?
Yes. Results are posted in the registry (first posted 16 Jan 2012). 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?
Number of Participants Reporting Adverse Events by System Organ Class After Vaccination With ACAM FLU A, or ACAM FLU A With Adjuvant, or a Placebo Vaccine. (time frame: Day 0 through Day 60 post-vaccination). The study lists 5 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 NCT00819013, which also lists 1 linked publication.
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 19 Jan 2012.
