About this study

Official title: A Randomized Controlled Clinical Trial Assessing the Immunologic Response to an FDA-approved Influenza Vaccine Delivered Using an FDA-Cleared Jet Injection Vaccine Delivery Device or a Needle and Syringe

The primary objective of this study was to evaluate if administration of a seasonal flu vaccine using a jet injector device is comparable to traditional needle and syringe delivery for eliciting an immune response. A secondary objective was to compare the safety of the two delivery methods.

Read the detailed description

Needle-free jet injection devices create a fine stream of pressurized liquid that is able to deliver vaccines and other pharmaceutical products beneath the skin. Design aspects such as quality, pressure, orifice size, angle of injection relative to skin and injection stream coherence control the depth to which the product is delivered. This technology provides a safer delivery option for patients and healthcare staff by removing the need for needles for the administration of vaccines.

In addition to improved safety, additional benefits of using jet injectors include more consistent and reliable dose volume delivery, reduced vaccine waste, diminished need to transport large quantities of sharps, reduced risk of needle sticks, syringe reuse, and costs associated with sharps waste. Jet injectors offer a needle-free procedure to those individuals who are adverse to needles.

This study compared the efficacy of a disposable syringe jet injection device (Stratis) with traditional needle and syringe (NS) administration for the delivery of a trivalent inactivated influenza vaccine. Efficacy was evaluated by comparing measures of hemagglutination inhibition (HI); specifically GMTs, seroconversion and seroprotection. Safety of the two administration devices was evaluated by comparison of incidence of solicited local and systemic adverse events.

What is being measured

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

  1. Anti Influenza Hemagglutination Inhibition (HAI) Antibody Geometric Mean Titers (GMT)

    The GMT criterion for non-inferiority for the upper limit of the 95% CIs of the GMT ratio (GMT with Needle-Free / GMT with Needle and Syringe) antigen will not exceed 1.5 fold.

    Measured: 28 days

  2. The Percentage of Participants Achieving Seroconversion

    Seroconversion is defined as a 4-fold rise in HAI titer in post-immunization serum relative to pre-immunization serum, or if pre-immunization serum had an undetectable titer (<1:10), attainment of a post-immunization titer of ≥1:40.

    Measured: 28 days

Secondary outcomes (1)
  1. Percentage of Subjects With Solicited Local or Systemic Adverse Events

    Vaccine reactogenicity will be collected on a patient-completed diary card daily for seven days post-vaccination. The following adverse events will be solicited on the diary card: injection site tenderness, injection site pain, injection site redness, injection site swelling, injection site itching, injection site bruising, fatigue, muscle aches, headache, decreased appetite, fever, pruritus.

    Measured: 4 days

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Stratis Jet Injector, Needle and Syringe and 2011-2012 Fluzone trivalent inactivated influenza vaccine in people with Influenza Prophylaxis, run by PharmaJet, Inc. at 1 site 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 5 inclusion and 11 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 20 Jun 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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 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 20 Jun 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?

Anti Influenza Hemagglutination Inhibition (HAI) Antibody Geometric Mean Titers (GMT) (time frame: 28 days). 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 20 Jun 2019.
