Trial summary

The hypothesis for this trial is that the incidence of a pre-defined composite of common systemic hypersensitivity adverse events for Flublok recipients is non-inferior to that reported for licensed IIV recipients. Another hypothesis is that the safety and reactogenicity of Flublok is clinically acceptable, i.e. Read more about this study

About this study

Official title: Comparison of the Safety of Flublok® Versus Licensed Inactivated Influenza Vaccine in Healthy, Medically Stable Adults ≥ 50 Years of Age

The hypothesis for this trial is that the incidence of a pre-defined composite of common systemic hypersensitivity adverse events for Flublok recipients is non-inferior to that reported for licensed IIV recipients. Another hypothesis is that the safety and reactogenicity of Flublok is clinically acceptable, i.e. consistent with the overall safety profiles previously observed with Flublok and with the licensed comparator.

Read the detailed description

The Advisory Committee on Immunization Practices (ACIP) recommends that all people aged 6 months and older be immunized to prevent influenza. Currently the only approved influenza vaccine across the entire age group is inactivated influenza vaccine (IIV). A Biologics Licensing Application (BLA) for Flublok was approved by the FDA for influenza immunization of adults 18-49 years of age. Additional safety and, ultimately efficacy, data is needed to support use in adults ≥50 years of age, an important age group as adults ≥65 years of age are among those at increased risk of influenza complications.

What participants receive

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

  • FlublokBiological

    A Biologics Licensing Application (BLA) for Flublok was approved by the FDA for influenza immunization of adults 18-49 years of age. Flublok is produced using recombinant technology under serum-free conditions.

  • AfluriaBiological

    Afluria is approved for use in persons 5 years of age and older and is produced by inactivation and disruption of live influenza virus grown in embryonated chicken eggs.

AfluriaPlacebo comparatorAfluria, containing 3x15µg (45µg total), of trivalent, inactivated influenza vaccine (licensed IIV) containing influenza antigen derived from A/H1N1 and A/H3N2 and influenza B viruses in a total volume of 0.5 mL

What is being measured

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

  1. Number of Participants With Common Hypersensitivity Reactions as Measure of Safety

    Number of participants who experience a pre-defined common systemic hypersensitivity adverse event, including rash, urticaria, swelling or edema through Day 30 post-vaccine administration.

    Measured: 30 Days

Secondary outcomes (3)
  1. Subjects With at Least One Unsolicited Adverse Event in the 30 Days Following Vaccine Administration

    Subjects with at least one serious adverse event and subjects with at least one medically-attended unsolicited adverse event occurring during the 30 days following vaccine administration

    Measured: 30 Days

  2. Number of Participants With Local and Systemic Events Reported as a Measure of Safety

    Number of solicited local and systemic events of reactogenicity reported with the help of a memory aid during the seven days following vaccine administration.

    Measured: 7 Days

  3. Subjects With at Least One Hypersensitivity Event Reported on Day 0 and Days 0-7 Following Vaccine Administration as a Measure of Safety

    Subjects with at least one pre-defined common systemic hypersensitivity adverse event, including rash, urticaria, swelling or non-dependent edema on Day 0 and for Days 0 to 7 following vaccine administration

    Measured: 7 Days

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Flublok and Afluria in people with Influenza, run by Protein Sciences Corporation at 14 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 18 Feb 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 14 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 18 Feb 2015). 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 Common Hypersensitivity Reactions as Measure of Safety (time frame: 30 Days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01825200, which also lists 1 linked publication.

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 18 Feb 2015.
