About this study

Official title: Evaluation of Natural Human Interferon Alpha Lozenges in the Prevention of Winter Colds and Flu in Perth, Western Australia

The aim of the study is to see if lozenges containing a low dose of interferon-alpha can prevent and/or reduce the severity of colds and flu. Starting about 1 month before the expected start of the winter colds and flu season in Perth, Australia, healthy volunteers will allow a lozenge containing interferon, or a lozenge containing no medicine (a placebo), to dissolve in their mouth once a day for 16 weeks. Blood tests at the start and end of treatment will determine whether interferon was able to prevent infections with cold/flu viruses. Once a week, volunteers will complete a survey about their cold/flu symptoms, medications taken, days of work missed, etc. to see if interferon was able to make their winter colds and flu less severe.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing interferon-alpha in people with Upper Respiratory Tract Infections, run by Ainos, Inc. (f/k/a Amarillo Biosciences Inc. at 1 site in Australia.

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 2 inclusion and 9 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 16 Sep 2011. 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 Australia. 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 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.

Yes. Results are posted in the registry (first posted 13 Jan 2011). 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?

Frequency of Influenza-like Illness (time frame: 16 weeks). 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 16 Sep 2011.
