Study population: Community Sample

Who may be able to join

  • Written informed consent was obtained and documented (after the investigator has given oral and written information about the study to the subject).

  • Subject with a baseline oxygen requirement > 2 l/min via nasal cannula
  • Any known contraindication to MRI examination
  • Inability to provide informed consent
  • A language, communication, cognitive or behavioral impairment that might interfere with fully informed consent

About this study

The purpose of this study is to determine the MRI characteristics of Chronic Obstructive Pulmonary Disease subjects both at baseline and yearly for a period of 5 years, and to correlate these biomarkers with pulmonary function tests, CT scan, 6 Minute-walk tests, and respiratory questionnaires.

The central hypothesis is that quantitative assessment of the lung through magnetic resonance imaging of hyperpolarized 3He can detect early alterations in structure and function which are precursors to clinically apparent COPD and that these precursors can be used to predict progression of disease earlier and better than established clinical methods.

Novel assessments using 3He MRI will lead to new information about COPD and will be critical for characterizing disease response to therapy. A secondary hypothesis is that a variety of technical improvements in the techniques of hyperpolarized gas MRI will accelerate the translation of this relatively new modality to clinical use.

What is being measured

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

  1. Smoking-Induced Alterations in the Regional Alveolar Oxygen Tension Heterogeneity [Torr] in Smokers Compared to Healthy Controls and COPD Subjects

    To measure the specificity and sensitivity of Regional Alveolar Oxygen Tension Heterogeneity in differentiation of healthy smokers from healthy nonsmokers and COPDs

    Measured: 2 years from baseline (+- 2 months)

  2. Smoking-Induced Alterations in the Apparent Diffusion Coefficient [cm^2/s] in Smokers Compared to Healthy Controls and COPD Subjects

    To measure the specificity and sensitivity of Apparent Diffusion Coefficient in differentiation of healthy smokers from healthy nonsmokers and COPDs

    Measured: 2 years from baseline (+- 2 months)

  3. Smoking-Induced Alterations in the Specific Ventilation [unitless] in Smokers Compared to Healthy Controls and COPD Subjects

    To measure the specificity and sensitivity of Specific Ventilation in differentiation of healthy smokers from healthy nonsmokers and COPDs

    Measured: 2 years from baseline (+- 2 months)

Questions about this trial

What is this clinical trial studying?

An observational study of Chronic Obstructive Pulmonary Disease (COPD), run by University of Pennsylvania 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 3 inclusion and 10 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 12 Apr 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was stopped early (reason given: The longitudinal goal could not be completed due to CT scans not being performed at baseline.). 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?

Smoking-Induced Alterations in the Regional Alveolar Oxygen Tension Heterogeneity [Torr] in Smokers Compared to Healthy Controls and COPD Subjects (time frame: 2 years from baseline (+- 2 months)). The study lists 3 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 12 Apr 2016.
