About this study

Official title: Randomised, Double-blind, Placebo-controlled, Phase I/II Study of Single Dose GHB16L2 Trivalent Influenza Vaccine in Healthy Adults

The purpose of this phase I/II trial is to evaluate safety and tolerability of a single dose of GHB16L2 administered by liquid nasal spray for vaccination against seasonal influenza virus infection. It is also performed to assess immunogenicity and pharmacokinetics (shedding).

Read the detailed description

GHB16L2 intends to provide a novel vaccination for influenza virus infection. 80 healthy volunteers will be included at a ratio of 1:1 for GHB16L2 or placebo. GHB16L2 will be administered once on day 1. Follow-up visits will be performed on days 2, 8 and 29.

    Measured: At day 29 (end of study)

  2. Determination of the presence of GHB16L2 in mucosal samples (viral recovery/shedding)

    Measured: 1 week post immunisation

  3. Immune response factor at day 29

    Immune response factors for HAI, MNA, IgA and IgG

    Measured: At day 29 (end of study)

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing GHB16L2 in people with Influenza, Human, run by AVIR Green Hills Biotechnology AG at 1 site in Austria.

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 17 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 10 Jan 2014. 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 Austria. 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 combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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?

Number of participants with Adverse Events (time frame: From baseline to 30 days after end of study). 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 NCT01369862, 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 10 Jan 2014.
