About this study
Official title: A Randomized, Double-Blind Trial on the Safety and Immunogenicity of Inactivated Trivalent Influenza Vaccine in Pregnant Women
In pregnant women, flu may cause complications like pneumonia (infection of the lungs) or hospitalization. In the United States (US) it is recommend that all women get flu vaccine if they are going to be pregnant or deliver during the flu season but only a few studies have measured a pregnant woman's immune response (the body's defense against the flu) after getting the flu vaccine. About 200, 18-39 year old, inclusive, pregnant women in their second or third trimester (from 14 weeks of gestation to term, inclusive) will be enrolled in this US based study. Participation will be about 8 months in duration. Women will be randomized (assigned by chance) to receive either Fluzone® or Fluarix®. Blood collection will occur on Day 0 and 28 days post vaccination.
Read the detailed description
Influenza is a significant cause of morbidity and mortality in the United States (US), resulting in an average of 226,000 hospitalizations and 36,000 deaths each year. Pregnant women and infants are at an increased risk for the complications of influenza. Severe disease, emergency department visits and hospitalizations occur frequently in pregnant women and infants which are considered high risk populations. In the US, routine vaccination with inactivated trivalent influenza vaccine (TIV) is recommended for pregnant women or those who deliver during the influenza season. Few studies exist on the safety and immunogenicity of administration of seasonal inactivated TIV despite long-standing recommendations. Although influenza vaccination has been recommended during pregnancy, the rates of immunization remain low, at about 13 percent. This is a multi-site randomized, double-blind clinical trial in 200 ambulatory, medically stable 18-39 year old, inclusive, pregnant women in their second or third trimester of pregnancy (from 14 weeks of gestation to term, inclusive). Study subjects will be randomized 1:1 to receive one dose of a 2008-2009 seasonal inactivated TIV, either Fluzone® or Fluarix® (100 pregnant women per vaccine group). Once enrolled, a blood sample will be collected and each subject will receive a single 0.5 mL dose of a 2008-2009 seasonal inactivated TIV, either Fluzone® or Fluarix®. The vaccination will occur on Day 0. Subjects will be observed for approximately 15 minutes after vaccination. All subjects will maintain a memory aid recording oral temperature, and systemic and local adverse events (AEs) for 7 days after each vaccination. Subjects will be encouraged to take their temperature around the same time each day. Subjects will have a phone call on Day 2 for review of memory aid, concomitant medication assessment, and assessment of AEs. Subjects will have a phone call on Day 8 for AE assessment, concomitant medication assessment and review of memory aid. At approximately Day 28 after the vaccination, subjects will return to the clinic for immunogenicity blood sample collection, concomitant medication assessment, and assessment of any AEs. A targeted physical exam will be conducted, if indicated. At approximately Day 180 or 6 months after vaccination, subjects will have a phone call for assessment for any serious adverse events (SAEs). Unsolicited non-serious AE data will be captured Day 0 through Day 28. Maternal SAE data will be captured throughout the study period (Day 0 through Day 180, approximately 6 months after dose of vaccine). Maternal and infant SAE data will be collected when obtaining data on pregnancy outcome. Serum for immunogenicity evaluations will be obtained prior to the dose of vaccine (at Day 0); and one month after vaccination (at Day 28). Pregnancy outcome data will be captured by a review of medical records and a phone call to the subject. Data include any complications during labor and delivery for both the mother as well as the neonate, to include premature delivery or delivery by emergency cesarean section. Neonatal assessments will include but not be limited to gestational age, birth weight, Apgar scores, congenital abnormalities, infection, hematological and metabolic complications, admission to nursery or Neonatal Intensive Care Unit and the need for respiratory support. Blood samples collected will be tested in a central laboratory for the levels of hemagglutination inhibition (HAI) and microneutralization (MN) antibodies.

The data collection process followed a prospectively-defined list of complications reported for this outcome measure, some of which may have also been reported as serious adverse events if otherwise meeting those requirements.
Measured: At time of delivery.
Number of Participants Reporting Neonatal Complications.
Participants were contacted after delivery, and medical records reviewed, to collect neonatal complications. The data collection process followed a prospectively-defined list of complications reported for this outcome measure, some of which may have also been reported as serious adverse events if otherwise meeting those requirements.
Measured: At time of delivery.
Number of Participants Reporting Serious Adverse Events (SAE)
Serious adverse events included any untoward medical occurrence that resulted in death of the mother, fetus or infant; was life threatening to mother, fetus or infant; was a persistent/significant disability/incapacity; required in-patient hospitalization or prolongation thereof; was a congenital anomaly/birth defect in fetus or infant; or may have jeopardized the mother, fetus or infant, or required intervention to prevent one of the outcomes. All events are included regardless of association to vaccination.
Measured: Through 6 months post vaccination.
Number of Participants Reporting Unsolicited Non-serious Adverse Events Considered Associated With Vaccination
Unsolicited non-serious adverse events were collected from participants at follow up contacts, either by phone or in clinic, through 28 days after vaccination. Association to vaccination was determined by a clinician licensed to make a medical diagnosis and listed on the site's Federal Drug Administration's Form 1572.
Measured: Day 0 through Day 28 post vaccination.
Number of Participants Reporting Solicited Injection Site Reactions at Each Severity Based on the Functional Grading Scale
Participants recorded a daily maximum severity at which local reactions of pain, tenderness and swelling were experienced.

Participants recorded a daily oral temperature on a memory aid for 8 days (Days 0-7) after vaccination. The protocol defined mild fever as oral temperatures 37.8 to less than 38 degree Celsius, moderate fever as 38 to less than 39 degrees Celsius and severe fever as oral temperatures of 39 degrees Celsius or higher. Participants are reported at the highest severity experienced across the 8 days.
Hemagglutination Inhibition Assay (HAI) Geometric Mean Titer (GMT) Against Each Antigen in the 2008-2009 Seasonal Influenza Trivalent Influenza Vaccine
Time frame: Day 0 prior to and Day 28 after receiving single dose.
Blood was collected for HAI assay at Day 0 prior to vaccination and again at 28 days following vaccination. The HAI assay was conducted with the three antigens in the 2008-2009 seasonal inactivated TIV: Influenza B antigen, H1N1 antigen, and H3N2 antigen.
Number of Participants With a Four-fold or Greater Rise in HAI Antibody Titer Against Each Antigen in the 2008-2009 Seasonal Influenza Trivalent Influenza Vaccine
Time frame: Day 0 prior to and Day 28 receiving a single dose.
Blood was collected for HAI assay at Day 0 prior to vaccination and again at 28 days following vaccination. The HAI assay was conducted with the three antigens in the 2008-2009 seasonal inactivated TIV: Influenza B antigen, H1N1 antigen, and H3N2 antigen. A participant met the threshold of a four-fold increase in titer if the Day 0 titer was less than 10 (the assay's lowest level of detection) and the Day 28 titer was 40 or greater, or the Day 0 titer was greater than or equal to 10, and the Day 28 titer was an increase by four-fold or more.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Fluzone® and Fluarix® in people with Influenza, run by National Institute of Allergy and Infectious Diseases (NIAID) at 9 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 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 13 Jun 2012. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 9 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
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 6 Apr 2011). 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 a Serum Hemagglutination Inhibition Assay (HAI) Antibody Titer Greater Than or Equal to 40 Against Each Antigen Included in the 2008-2009 Seasonal Inactivated Trivalent Influenza Vaccine (TIV) (time frame: Day 0 prior to and Day 28 after receiving single dose.). The study lists 11 primary outcomes in all. 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 13 Jun 2012.
