Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 49 years
  • All sexes
  • Healthy volunteers accepted
  • Adult

Who may be able to join

  • Healthy adult male or female, 18-49 years of age
  • Willing and able to give informed consent prior to study enrollment
  • Able to comply with study requirements
  • Women of child-bearing potential must have a negative urine pregnancy test at vaccination, will be advised through the Informed Consent process to avoid becoming pregnant over the duration of the study, and must assert that they will employ an effective form of birth control for the duration of the study. Acceptable forms of birth control are: credible history of continuous abstinence from heterosexual activity, or prior surgical sterilization, hormonal contraceptives (oral, injectable, implant, patch, ring), barrier contraceptives (condom or diaphragm), and intrauterine device (IUD). Women with an adequately documented history of surgical sterility are exempt from urine pregnancy testing.

Who cannot join

  • Any ongoing, symptomatic acute or chronic illness requiring medical or surgical care.
  • Asymptomatic conditions or findings (e.g., mild hypertension, dyslipidemia) that are not associated with evidence of end-organ damage are not exclusionary provided that they are being appropriately managed and are clinically stable (i.e., unlikely to result in symptomatic illness within the time-course of this study) in the opinion of the investigator.
  • Acute or chronic illnesses or conditions which may be reasonably predicted to become symptomatic if treatment were withdrawn or interrupted are exclusionary, even if stable.
  • Acute or chronic illnesses reasonably expected to be associated with increased risks associated with influenza (e.g., cardio-pulmonary diseases, diabetes mellitus, renal or hepatic dysfunction, hemoglobinopathies) are exclusionary, even if stable.
  • Note that illnesses or conditions may be exclusionary, even if otherwise stable, due to therapies used to treat them (see exclusion criteria 2,5,8,9).
  • Participation in research involving investigational product (drug/ biologic/ device) within 45 days before planned date of first vaccination
Show all 18Show fewer
  • History of a serious reaction to prior influenza vaccination, known allergy to constituents of licensed TIV (e.g., egg proteins) or polysorbate-80.
  • History of Guillain-Barré Syndrome (GBS) within 6 weeks following a previous influenza vaccine.
  • Received any vaccine in the 4 weeks preceding the study vaccination and any influenza vaccine within six months preceding the study vaccination.
  • History of receipt of any avian influenza vaccine containing an H5 antigen, or known exposure to birds infected with an H5 virus.
  • Any known or suspected immunosuppressive illness, congenital or acquired, based on medical history and/or physical examination.
  • Chronic administration (defined as more than 14 continuous days) of immunosuppressants or other immune-modifying drugs within 6 months prior to the administration of the study vaccine. An immunosuppressant dose of glucocorticoid will be defined as a systemic dose greater or equal to 10mg of prednisone per day or equivalent. The use of topical, inhaled, and nasal glucocorticoids will be permitted.
  • Administration of immunoglobulins and/or any blood products within the three months preceding the administration of the study vaccine or during the study.
  • Acute disease at the time of enrollment (defined as the presence of a moderate or severe illness with or without fever, or an oral temperature >38.0°C on the planned day of vaccine administration.
  • Any condition that in the opinion of the investigator would pose a health risk to the subject if enrolled or could interfere with evaluation of the vaccine or interpretation of study results (including neurologic or psychiatric conditions deemed likely to impair the quality of safety reporting).
  • Known disturbance of coagulation.
  • Women who are breastfeeding or plan to become pregnant during the study.
  • Suspicion or recent history (within one year of planned vaccination) of alcohol or other substance abuse.

About this study

Official title: A Phase 2 Randomized, Observer-Blind, Dose-Ranging Study to Evaluate the Immunogenicity and SAfety of Quadrivalent Seasonal Virus-Like Particle (VLP) Influenza Vaccine (Recombinant) in Healthy Young (18-49) Adults

The purpose of this study is to determine the immune response of three dose levels of the Quadrivalent VLP vaccine in healthy young (18-49) adults. The study is broken down into four treatment groups. Each group will enroll 100 subjects, for a total of 400 subjects. Groups A-C will receive one of three dose levels of the Quadrivalent VLP vaccine, and Group D will receive a commercially available trivalent influenza vaccine (TIV). The study will also evaluate the safety and tolerability of the Quadrivalent VLP vaccine formulations.

What is being measured

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

  1. Immunogenicity of the quadrivalent VLP vaccine using HAI responses.

    Derived/calculated endpoints based on:

    Seroconversion rate (SCR) Seroprotection rate (SPR) Geometric mean titer (GMT) Geometric mean ratio (GMR)

    Measured: Up to 6 months

  2. Safety of three quadrivalent VLP vaccine formulations. adverse events, Medically Attended Events (MAEs), Serious Adverse Events (SAEs), and Significant New medical Conditions (SNMCs)

    Number and percentage of subjects with solicited local and systemic adverse events over the seven days post-injections; all adverse events (including adverse changes in clinical laboratory parameters) over 21 days post-injections; and Medically Attended Events (MAEs), Serious Adverse Events (SAEs), and Significant New medical Conditions (SNMCs) through six months.

    Measured: Up to 6 months

Secondary outcomes (1)
  1. Immunogenicity of each quadrivalent VLP vaccine formulation measured by neuraminidase inhibition (NAI)

    Derived/calculated endpoints based on:

    Two fold and four fold increases in NAI titer Geometric mean titer (GMT) Geometric mean ratio (GMR)

    Measured: Up to 6 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Quadrivalent VLP Vaccine and Comparator TIV in people with Influenza, run by Novavax at 5 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 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 23 Sep 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 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?

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.

What does the primary outcome measure?

Immunogenicity of the quadrivalent VLP vaccine using HAI responses. (time frame: Up to 6 months). The study lists 2 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 23 Sep 2016.
