What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Participants With Solicited Injection-Site or Systemic Reactions After Receipt of the 2015-2016 Formulation of Fluzone Quadrivalent, Fluzone Intradermal Quadrivalent, or Fluzone High-Dose Vaccine
Solicited injection-site reactions: Pain, Erythema, Swelling, Induration, and Ecchymosis. Solicited systemic reactions: Fever, Headache, Malaise, Myalgia, and Shivering. Grade 3 solicited injection-site reactions: Pain, Significant; prevents daily activity. Erythema, Swelling, Induration, and Ecchymosis >100 mm. Grade 3 solicited systemic reactions: Fever, ≥ 39.0°C or ≥ 102.1°F; Headache, Malaise, Myalgia, and Shivering, Significant; prevents daily activity.
A participant (18 to < 65 Years) who was randomly assigned to receive Fluzone Intradermal Quadrivalent vaccine received Fluzone Quadrivalent vaccine instead; this participant was excluded from the Per-protocol analysis Set and was included in the Fluzone Quadrivalent vaccine Group in the Safety Analysis Set and the assigned group in the Full Analysis Set.
Measured: Day 0 up to Day 7 post-vaccination
Secondary outcomes (4)
Geometric Mean Titers of Influenza Antibodies Pre- and Post-Vaccination With the 2015-2016 Formulation of Fluzone Quadrivalent, Fluzone Intradermal Quadrivalent, or Fluzone High-Dose Vaccine
Anti-influenza antibodies were measured using an hemagglutination inhibition assay.
Measured: Day 0 (pre-vaccination) and 21 days post-vaccination
Number of Participants Achieving Seroprotection Pre and Post-Vaccination With the 2015-2016 Formulation of Fluzone Quadrivalent, Fluzone Intradermal Quadrivalent, or Fluzone High-Dose Vaccine
Anti-influenza antibodies were measured using an hemagglutination inhibition assay. Seroprotection was defined as the number of participants with a titer ≥ 40 (1/dilution) at pre-vaccination and 21 days post-vaccination.
Measured: Day 0 (Pre-vaccination) and 21 days post-vaccination
Number of Participants Achieving Seroconversion Following Vaccination With the 2015-2016 Formulation of Fluzone Quadrivalent, Fluzone Intradermal Quadrivalent, or Fluzone High-Dose Vaccine

Measured: 21 days post-vaccination
Geometric Mean Titer Ratios of Influenza Antibodies Post-Vaccination With the 2015-2016 Formulation of Fluzone Quadrivalent, Fluzone Intradermal Quadrivalent, or Fluzone High-Dose Vaccine

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Fluzone Quadrivalent vaccine, 2015-2016 formulation, No Preservative, Fluzone Intradermal Quadrivalent vaccine, 2015-2016 formulation and Fluzone High-Dose vaccine, 2015-2016 formulation in people with Influenza, run by Sanofi Pasteur, a Sanofi Company at 4 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 3 inclusion and 18 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 12 Dec 2016. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 4 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. 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 12 Dec 2016). 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 With Solicited Injection-Site or Systemic Reactions After Receipt of the 2015-2016 Formulation of Fluzone Quadrivalent, Fluzone Intradermal Quadrivalent, or Fluzone High-Dose Vaccine (time frame: Day 0 up to Day 7 post-vaccination). 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 12 Dec 2016.
