  • Prior receipt of blood, blood-derived products or immunoglobulins in the 6 months prior to administration of study vaccine, or planning to receipt such product during the study period.
  • Use of drugs that can affect immune response such as systemic corticosteroids (excluding topical preparations and inhaled preparations) or immunosuppressive drugs in the 30 days before study vaccination and/or in the first 28 days following study vaccination, with the exceptions that a short course of corticosteroids ≤10 days duration, or a single injection for a self-limited condition at least 2 weeks prior to enrolment will not exclude study participation.
  • Current intake of drugs that increase bleeding risk, e.g. anticoagulant medication (coumarin derivatives, low molecular weight heparin, DOAC).
  • Current anti-tuberculosis prophylaxis or therapy.
  • Use of non-steroidal anti-inflammatory drugs (NSAIDs) and/or planning a medical procedure under full anesthesia on the day of study vaccination and/or in the first 14 days following study vaccination with the exception of a medical indication.

About this study

Official title: A Randomized First-in-human, Observer-blind, 3-arm Study to Evaluate Safety, Tolerability, and Immunogenicity of a Single Administration of TETRALITE, a Novel Adjuvanted, Low-dose Influenza Vaccine

There is an obvious need for an affordable and more effective seasonal influenza vaccine. TETRALITE is a novel, inactivated, adjuvanted influenza vaccine combining a low dose of a licensed vaccine with the novel, potent LiteVax Adjuvant.

A licensed vaccine (Cohort 1) with a normal dose [15 ug per strain] and no adjuvant will be compared with two TETRALITE study vaccines with 1/5th of the licensed vaccine added with a low (Cohort 2) or high (Cohort 3) dose of LiteVax Adjuvant.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing TETRALITE in people with Influenza, run by LiteVax BV at 1 site in Belgium.

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 7 inclusion and 26 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 25 Jan 2024. 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 Belgium. 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 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.

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?

Safety and tolerability of a single, intramuscular injection with TETRALITE (time frame: 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 25 Jan 2024.
