About this study

Official title: A Phase 4, Randomized, Double-blind, Placebo Controlled Study to Evaluate the Safety of 2 New of 6:2 Influenza Virus Reassortants in Adults

This prospective annual release study is designed to evaluate the safety of 2 new influenza virus vaccine strains to be included in FluMist Quadrivalent for the 2018-2019 influenza season.

Read the detailed description

This prospective. randomized, double-blind. placebo-controlled release study will enroll approximately 300 healthy adults 18 to 49 years of age (not yet reached their 50th birthday). Eligible subjects will be randomly assigned in a 4:1 fashion to receive a single dose of bivalent vaccine or placebo by intranasal spray. Randomization will be stratified by site. This study will be conducted at 2 sites in the United States of America. Each subject will receive 1 dose of investigational product on Day 1. The duration of study participation for each subject is the time from study vaccination through 180 days after study vaccination.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Bivalent influenza vaccineBiological

    A single dose of bivalent vaccine (10^7±5 fluorescent focus unit of 2 cold-adapted, attenuated, temperature-sensitive, 6:2 reassortant influenza strain) will be administered as intranasal spray on Day 1.

  • PlaceboOther

    A single dose of placebo matched to bivalent influenza vaccine will be administered as intranasal spray on Day 1.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percentage of Participants Reporting Fever (Oral Temperature >= 101 Degrees Fahrenheit) Through Day 8

    Percentage of participants with fever (oral temperature >= 101 degrees Fahrenheit) through Day 8 is reported.

    Measured: Day 1 through Day 8

Secondary outcomes (5)
  1. Number of Participants With Solicited Symptoms Through Day 8

    For this study, solicited symptoms included oral fever (> 100 degrees Fahrenheit), runny nose, sore throat, cough, vomiting, muscle aches, chills, decreased activity (tiredness), and headache.

    Measured: Day 1 through Day 8

  2. Number of Participants With Solicited Symptoms Through Day 15

    For this study, solicited symptoms included oral fever (> 100 degrees Fahrenheit), runny nose, sore throat, cough, vomiting, muscle aches, chills, decreased activity (tiredness), and headache.

    Measured: Day 1 through Day 15

  3. Number of Participants With Treatment-emergent Adverse Events (TEAEs) Through Day 8 and Day 15

    An adverse event (AE) is any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. The TEAEs are defined as events present at baseline that worsened in intensity after administration of study drug or events absent at baseline that emerged after administration of study drug.

    Measured: Day 1 through Day 8; Day 1 through Day 15

  4. Number of Participants With Treatment-emergent Serious Adverse Events (TESAEs) Through Day 29 and Day 181

    An adverse event (AE) is any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. A serious adverse event (SAE) is an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. The TEAEs are defined as events present at baseline that worsened in intensity after administration of study drug or events absent at baseline that emerged after administration of study drug.

    Measured: Day 1 through Day 29; Day 1 through Day 181

  5. Number of Participants With New Onset Chronic Diseases (NOCDs) Through Day 29 and Day 181

    An NOCD is a newly diagnosed medical condition that is of a chronic, ongoing nature and is assessed by the investigator as medically significant.

    Measured: Day 1 through Day 29; Day 1 through Day 181

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Bivalent influenza vaccine in people with Influenza and Healthy, run by MedImmune LLC 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 4 inclusion and 6 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 26 Dec 2019. 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. 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 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 26 Dec 2019). 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?

Percentage of Participants Reporting Fever (Oral Temperature >= 101 Degrees Fahrenheit) Through Day 8 (time frame: Day 1 through Day 8). 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 26 Dec 2019.
