About this study

Evidence in animals shows that losartan can prevent or reverse inflammation and lung damage due to smoking. The goal of this study is to determine whether this drug which is also used to treat hypertension can stabilize or improve lung function in people who have from chronic obstructive pulmonary disease (COPD).

Read the detailed description

Participants will be given either losartan in a dose of 50-100 mg per day for a period of one year. During that time, they will have lung function tests, breathing tests, and computed tomograms of the chest. These tests will determine whether there is inflammation in the lung and whether there is progressive involvement of the lung with COPD.

What is being measured

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

  1. Change in Percent Emphysema on CT Scan

    Percent emphysema calculated as percent of CT voxels less than -950 HU measured at TLC. Analysis limited to patients with 5-35% emphysema on CT scan at baseline.

    Measured: Change between baseline and month 12.

Secondary outcomes (1)
  1. Change in FEV1 (L)

    Change in FEV1 (L) post-bronchodilator from baseline to 12 months. Analysis includes only participants with 5-35% emphysema at baseline.

    Measured: Measured at Baseline and Month 12

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Losartan in people with COPD and Emphysema, run by Johns Hopkins University 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 1 inclusion and 1 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 Apr 2017. 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 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 25 Apr 2017). 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?

Change in Percent Emphysema on CT Scan (time frame: Change between baseline and month 12.). 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 Apr 2017.
