About this study

Official title: Development and Validation of a Prognostic Transcriptomic Signature for Chronic Hypersensitivity Pneumonitis

Up to 150 patients with hypersensitivity pneumonitis will be enrolled at 7 clinical centers across the United States. Patients will be followed for 24 months to determine if biomarkers in the blood can predict disease progression.

Read the detailed description

Hypersensitivity pneumonitis is an immunologically mediated form of lung disease, resulting from inhalation exposure to a large variety of antigens. For unknown reasons, a subgroup of patients with HP without a known inciting antigen exposure develops chronic disease with progressive pulmonary fibrosis (the leading cause of death). Accurately identifying patients at risk of disease progression is necessary for prognosis and therapy.

Enrolled subjects will be followed for 24 months and complete 5 visits to one of the study centers. Blood biomarkers will be collected in addition to other clinical data to determine if these biomarkers can predict disease progression.

Questions about this trial

What is this clinical trial studying?

An observational study of Hypersensitivity Pneumonitis, run by National Jewish Health at 7 sites 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 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: under way, not looking for participants, as of the sponsor's last update on 9 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 7 sites 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?

This study is still under way. Results are not available in the source record yet.

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?

Time to absolute FVC (percent predicted) decline ≥10 percent (time frame: Up to 24 months). The study lists 40 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 9 Apr 2026.
