A Prognostic Transcriptomic Signature for Chronic Hypersensitivity Pneumonitis

Brief Title

A Prognostic Transcriptomic Signature for Chronic Hypersensitivity Pneumonitis

Official Title

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

Brief Summary

      Up to 135 patients with hypersensitivity pneumonitis will be enrolled at 5 clinical centers
      across the United States. Patients will be followed for 24 months to determine if biomarkers
      in the blood can predict disease progression.

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.
