About this study

The purpose of this study is to investigate the role of the pulmonary vasculature in the development and progression of chronic obstructive pulmonary disease (COPD). To accomplish this, an inhaled prostacyclin (iloprost) will be given to patients with COPD and changes in oxidative stress and lung volumes during exercise will be measured.

Read the detailed description

Chronic obstructive pulmonary disease (COPD), the 3rd leading cause of death in the US, is a progressive disorder for which new treatments are urgently needed, as existing therapies are focused primarily on symptom relief. Oxidative stress, in part arising from inducible nitric oxide synthase (iNOS) released by the pulmonary vasculature, is critical for the development and progression of COPD; a treatment strategy focused on the pulmonary vasculature is hypothesized to be beneficial in COPD patients. This will be studied with the use of an inhaled prostacyclin analogue, iloprost, which has been approved for pulmonary hypertension and investigated in small studies of COPD patients. Potential mechanisms include reductions in dynamic hyperinflation during exercise in COPD patients or improvements in oxidative stress

What is being measured

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

  1. Dynamic hyperinflation during maximal cardiopulmonary exercise test

    Dynamic hyperinflation will be measured as EELV/TLC ratio (end-expiratory lung volume/total lung capacity ratio) during exercise

    Measured: Acute response (exercise testing performed 30 minutes after study drug administration)

Secondary outcomes (10)
  1. Blood markers of oxidative stress

    8-isoprostane, superoxide dismutase, catalase, nitrite, malondialdehyde

    Measured: Acute response (measured 10 minutes, 30 minutes, 40 minutes, and 100 minutes after study drug administration)

  2. Blood markers of inflammation

    IL-1 beta, IL-6, IL-8, IL-10, IL-13, IL-18, TNF-alpha

    Measured: Acute response (measured 10 minutes, 30 minutes, 40 minutes, and 100 minutes after study drug administration)

  3. Dead space fraction

    Measured: Acute response (measured every 2 minutes during exercise, starting 30 minutes after study drug administration)

  4. B-type natriuretic peptide

    Measured: Acute response (measured 30 and 40 minutes after study drug administration)

  5. Partial pressure of oxygen

    Measured: Acute response (measured 30 minutes after study drug administration and every 2 minutes during exercise)

  6. Metabolic and gas exchange parameters during cardiopulmonary exercise test

    Measured: Acute response (throughout exercise, starting 30 minutes after study drug administration)

  7. Blood cyclic AMP levels

    Measured: Acute response (measured 10 minutes, 30 minutes, 40 minutes, and 100 minutes after study drug administration)

  8. Blood iloprost levels

    Measured: Acute response (measured 10 minutes, 30 minutes, 40 minutes, and 100 minutes after study drug administration)

  9. Exercise time and external work performed

    Measured: measured during exercise test 30 minutes after study drug administration

  10. Borg dyspnea and leg scores

    Measured: During exericse (starting 30 minutes after study drug administration)

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Inhaled iloprost 5.0 mcg in people with Chronic Obstructive Pulmonary Disease, run by Louisiana State University Health Sciences Center in New Orleans 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 5 inclusion and 8 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 Dec 2016. 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 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?

Dynamic hyperinflation during maximal cardiopulmonary exercise test (time frame: Acute response (exercise testing performed 30 minutes after study drug administration)). 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 Dec 2016.
