A Phase 1 study testing Fluzone in people with Influenza, run by National Institute of Allergy and Infectious Diseases (NIAID) at 2 sites in United States.
Trial summary
This study proposes to enroll 50 young infants, ages 10 to 22 weeks. Each of the fifty infants will receive two 0.25mL doses of preservative-free Fluzone®, given a minimum of 28 days apart but no more than 42 days apart.

About this study
Official title: Prospective Pilot Safety Study Administering Two Doses of Inactivated Influenza Vaccine to Infants 10-22 Weeks of Age
This study proposes to enroll 50 young infants, ages 10 to 22 weeks. Each of the fifty infants will receive two 0.25mL doses of preservative-free Fluzone®, given a minimum of 28 days apart but no more than 42 days apart. Preservative-free Fluzone® will not be administered at the same time as other routine vaccines. Approximately 2-3mLs of blood sample will be obtained prior to the first vaccination, approximately 4 weeks after the second vaccination and 6 months after the second vaccination for the measurement of immune response. The primary purpose of this study is twofold: 1.) To determine the safety of administering two doses of preservative-free Fluzone® to young infants and 2.) To determine the capability of inducing an immune response of administering two doses of preservative-free Fluzone® to young infants.
Read the detailed description
Influenza virus is an important global cause of morbidity and mortality. Influenza A or B viruses cause epidemics of disease almost every winter in the United States with an average of 36,000 deaths and 114,000 hospitalizations each year during 1990s (superscript 1). Children have the highest rates of infection while adults greater than 50 years of age have the highest mortality rates (superscript 2). Influenza, however, is associated with hospitalizations in young infants. In a survey of the Tennessee Medicaid database over many years, Neuzil et. al reported hospitalization rates in children less than 6 months of age that were much higher than in older children, and the rates approached those over 65 years of age (superscript 3). This is a prospective, phase l, open-label, self-contained, four visits over a period of 7 months, pilot study of 50 healthy infants, aged 10-22 weeks, with history of up-to-date routine immunizations, to assess safety and immunogenicity of administering 2 pediatric doses (with a minimum 4 weeks apart) of 0.25 ml of trivalent Influenza vaccine (Fluzone®). Each of the 50 infants will receive two 0.25mL doses of preservative free Fluzone®, given a minimum of 28 days apart but no more than 42 days apart. Preservative-free Fluzone® will not be administered at the same time as other routine vaccines. Approximately 2-3 mLs of venous blood will be obtained prior to the first vaccination, approximately 4 weeks after the second vaccination and 6 months after the second vaccination for the measurement of neutralization and HAI titers. Infants will be closely monitored during the influenza season for respiratory symptoms, fever, or other influenza-like illnesses. They will be seen during these episodes and nasal washes will be collected for a viral screen that will include culture for influenza virus, respiratory syncytial virus (RSV), adenovirus and parainfluenza virus and rapid test for influenza and RSV. Blood collected at the follow up visit, 6 months after the second dose of Fluzone®, will be used to measure post season antibody titers to strains of influenza A and B.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Fluzone in people with Influenza, run by National Institute of Allergy and Infectious Diseases (NIAID) at 2 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 6 inclusion and 9 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 Aug 2011. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 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 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.
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 Aug 2011.
