About this study

Official title: Evaluation of Natural Human Interferon Alpha Lozenges in the Treatment of Chronic Cough in Patients With Chronic Obstructive Pulmonary Disease (COPD) or Idiopathic Pulmonary Fibrosis (IPF)

The purpose of this study is to determine whether lozenges containing interferon-alpha can reduce the frequency and severity of coughing in patients with chronic obstructive pulmonary disease (COPD) and idiopathic pulmonary fibrosis (IPF).

Read the detailed description

Both chronic obstructive pulmonary disease (COPD) and idiopathic pulmonary fibrosis (IPF) frequently lead to a chronic cough that negatively impacts the quality of life (QOL) for patients and those around them. This is a randomized, double-blind, placebo-controlled trial to determine whether interferon-alpha, delivered in low doses via orally dissolving lozenges given 3 times per day for 4 weeks, can reduce the frequency and severity of chronic cough in patients with COPD or IPF. Cough frequency will be assessed via 24-hour digital audio recordings made prior to entry, and at weeks 2 and 4 of treatment. Cough severity will be assessed via a 100-mm visual analog scale questionnaire completed by the subject prior to entry and then weekly during treatment. Subjects will also complete questionnaires regarding cough frequency, duration and intensity, QOL, dyspnea, and antitussive medication usage weekly during treatment. All questionnaires will be repeated weekly during a 4-week post-treatment observation period to assess durability of response.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing interferon-alpha lozenges in people with Pulmonary Disease, Chronic Obstructive and Pulmonary Fibrosis, run by Ainos, Inc. (f/k/a Amarillo Biosciences 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 12 inclusion and 5 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: stopped early, as of the sponsor's last update on 24 Apr 2012. 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. 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.

Are results available for this study?

The study was stopped early (reason given: Insufficient patient accrual). Results are not available in the source record.

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/severity of cough (time frame: weekly). 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 NCT00690885, 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 24 Apr 2012.
