Trial summary

Chronic lung diseases are disorders associated with abnormalities in any of the structures involved in the process of breathing and bringing oxygen into the lungs and blood. This includes abnormalities in the airways, lungs, blood vessels in and around the lungs, and the tissue covering the lungs (pleura). Read more about this study

About this study

Official title: Comprehensive Evaluation of the Etiology and Pathogenesis of Chronic Lung Disease (Screening Protocol)

Chronic lung diseases are disorders associated with abnormalities in any of the structures involved in the process of breathing and bringing oxygen into the lungs and blood. This includes abnormalities in the airways, lungs, blood vessels in and around the lungs, and the tissue covering the lungs (pleura).

The purpose of this research study is to evaluate patients referred to the Cardiovascular and Pulmonary Branch of the National Heart, Lung, and Blood Institute (NHLBI) in order to;

  1. Develop a better understanding of the causes and disease processes involved in disorders of the lungs
  2. Identify patients eligible to participate in other P-CCMB research studies
Read the detailed description

The chronic lung diseases are those disorders associated with functional and/or structural derangement to the alveolar structures, airways, pulmonary blood vessels, pleura and/or mediastinum. The purpose of this project is to permit the comprehensive evaluation of patients referred to the Pulmonary Branch of the National Heart, Lung, and Blood Institute (NHLBI) in order to: (1) develop an understanding of the etiology and pathogenesis of these disorders; and (2) identify individuals who will be suitable candidates for other NHLBI protocols. Testing and procedures will only be performed when medically indicated for the purposes of making a diagnosis or obtaining information likely to be useful in the management of the subjects' disease or condition.

Questions about this trial

What is this clinical trial studying?

An observational study of Pulmonary Disease, run by National Heart, Lung, and Blood Institute (NHLBI) 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 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 1 Jun 2022. 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 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?

N/A-screening protocol (time frame: 1 Visit). 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 1 Jun 2022; AzTrials last refreshed its copy on 7 Nov 2026.
